Part 2 of this series explores how to customize the Next.js storefront to add a Wholesaler login form and display B2B products.

Medusa B2B Part 2: Set Up B2B Storefront - Featured image

Notice Medusa is under active development, so the content of this post may be outdated. Please check out our documentation instead.

In part 1 of the B2B series, you learned how to set up your Medusa server for a B2B ecommerce use case. You set up a B2B Sales Channel, Customer Groups, and Price List. You also added an endpoint that checks whether a customer is a B2B customer or not.

In this part of the series, you’ll customize Medusa’s Next.js storefront to add a Wholesaler login screen and a different way of displaying products for B2B customers. You’ll also explore how the checkout flow works for B2B customers.

You can find the full code for this tutorial series in this GitHub repository.

Install Next.js Storefront

In your terminal, run the following command to install the Next.js Storefront:

1
npx create-next-app -e https://github.com/medusajs/nextjs-starter-medusa b2b-storefront

This installs the Next.js storefront in a newly created directory Copy to clipboardb2b-storefront.

Then, change to the Copy to clipboardb2b-storefront directory and rename the Copy to clipboard.env.template file:

12
cd b2b-storefront
mv .env.template .env.local

Install Dependencies

To ensure you’re using the latest version of Medusa dependencies, run the following command to update Medusa dependencies:

1
npm install @medusajs/medusa@latest @medusajs/medusa-js@latest medusa-react@latest

In addition, install Copy to clipboardaxios to send requests to the custom endpoint you created in the previous tutorial:

1
npm install axios

Add Sales Channel Environment Variable

You’ll be using the Sales Channel you created in the first part to retrieve B2B products for B2B customers and to set the correct Sales Channel for B2B customers’ carts.

So, you need to set the ID of the sales channel in an environment variable.

If you’re unsure what the ID of the sales channel is, you can send a request to the List Sales Channel admin endpoint. You should find a Sales Channel with the name “B2B”. Copy the ID of that Sales Channel.

Then, add the following environment variable in Copy to clipboard.env.local:

1
NEXT_PUBLIC_SALES_CHANNEL_ID=<YOUR_SALES_CHANNEL_ID>

Where Copy to clipboard<YOUR_SALES_CHANNEL_ID> is the ID of the B2B Sales Channel.

In this section, you’ll add a login page specific to B2B customers. This requires adding some new pages and files, but also customizing existing logic.

Change AccountContext

The Next.js storefront defines an Copy to clipboardAccountContext that allows you to get access to customer-related data and functionalities across your storefront. You need to make changes to it to add a new variable to the context: Copy to clipboardis_b2b. This variable will allow you to check whether the customer is a B2B customer or not throughout the storefront.

In Copy to clipboardsrc/lib/context/account-context.tsx, add the Copy to clipboardis_b2b attribute to the Copy to clipboardAccountContext interface:

1234
interface AccountContext {
  //...
  is_b2b: boolean
}

Then, at the beginning of the Copy to clipboardAccountProvider function, add a new state variable Copy to clipboardis_b2b:

1234
export const AccountProvider = ({ children }: AccountProviderProps) => {
  const [is_b2b, setIsB2b] = useState(false)
    //...
}

Next, add a new callback function Copy to clipboardcheckB2b inside the Copy to clipboardAccountProvider function:

123456789101112131415161718192021222324
import axios from "axios"
import { useRouter } from "next/router"
import { MEDUSA_BACKEND_URL, medusaClient } from "@lib/config"
//...

export const AccountProvider = ({ children }: AccountProviderProps) => {
    //...
    const checkB2b = useCallback(async () => {
    if (customer) {
      //check if the customer is a b2b customer
      const { data } = await axios.get(`${MEDUSA_BACKEND_URL}/store/customers/is-b2b`, {
        withCredentials: true
      })
      setIsB2b(data.is_b2b)
    } else {
      setIsB2b(false)
    }
  }, [customer])

    useEffect(() => {
    checkB2b()
  }, [checkB2b])
    //...
}

This function sends a request to the Copy to clipboard/store/customers/is-b2b endpoint that you created in part 1. It then changes the value of the Copy to clipboardis_b2b state variable based on the response received.

You also run this callback function in Copy to clipboarduseEffect which triggers the function whenever there’s a change in the callback. In other words, whenever the Copy to clipboardcustomer is changed.

You also need to set the value of Copy to clipboardis_b2b back to Copy to clipboardfalse when the customer logs out. You can add that in the Copy to clipboardhandleLogout function in Copy to clipboardAccountProvider:

12345678
const handleLogout = () => {
    useDeleteSession.mutate(undefined, {
      onSuccess: () => {
        //...
        setIsB2b(false)
      },
    })
  }

Lastly, pass Copy to clipboardis_b2b in the Copy to clipboardvalue prop of Copy to clipboardAccountContext.Provider:

12345678910
return (
    <AccountContext.Provider
      value={{
        //...
        is_b2b
      }}
    >
      {children}
    </AccountContext.Provider>
  )

These are all the changes necessary to enable checking whether the customer is a B2B customer or not throughout the storefront.

There’s also one last change to make that enhances the customer experience. Change the Copy to clipboardcheckSession function in Copy to clipboardAccountProvider to the following:

12345
const checkSession = useCallback(() => {
  if (!customer && !retrievingCustomer) {
    router.push(router.pathname.includes("wholesale") ? "/wholesale/account/login" : "/account/login")
  }
}, [customer, retrievingCustomer, router])

Previously, the function redirects the customer to Copy to clipboard/account/login if they were trying to access account pages. To ensure that a guest customer gets redirected to the wholesaler login page when they try to access a wholesale page, you add a condition that determines where the guest customer should be redirected.

Change StoreContext

The Next.js storefront also defines a Copy to clipboardStoreContext that manages the store’s regions, cart, and more.

In this section, you’ll make changes to the Copy to clipboardStoreContext to ensure the correct sales channel is assigned to B2B customers’ carts.

In Copy to clipboardsrc/lib/context/store-context.tsx, change the Copy to clipboardcreateNewCart function in the Copy to clipboardStoreProvider function to the following:

123456789101112131415161718192021222324252627282930313233343536373839404142
import { MEDUSA_BACKEND_URL, medusaClient } from "@lib/config"
import axios from "axios"
import React, { createContext, useCallback, useContext, useEffect, useState } from "react"
//...

export const StoreProvider = ({ children }: StoreProps) => {
    //...
    const createNewCart = async (regionId?: string) => {
    const cartData: {
      region_id?: string,
      sales_channel_id?: string
    } = { region_id: regionId }

    if (process.env.NEXT_PUBLIC_SALES_CHANNEL_ID) {
      //check if customer is b2b
      const { data } = await axios.get(`${MEDUSA_BACKEND_URL}/store/customers/is-b2b`, {
        withCredentials: true
      })

      if (data.is_b2b) {
        cartData.sales_channel_id = process.env.NEXT_PUBLIC_SALES_CHANNEL_ID
      }
    }

    await createCart.mutateAsync(
      cartData,
      {
        onSuccess: ({ cart }) => {
          setCart(cart)
          storeCart(cart.id)
          ensureRegion(cart.region)
        },
        onError: (error) => {
          if (process.env.NODE_ENV === "development") {
            console.error(error)
          }
        },
      }
    )
  }
    //...
}

Previously, this function only passed the region ID to the Copy to clipboardcreateCart mutation. By making the above change you check first if the customer is a B2B customer and add the Copy to clipboardsales_channel_id field to the data to be passed to the Copy to clipboardcreateCart mutation.

Next, change the Copy to clipboardresetCart function in the Copy to clipboardStoreProvider function to the following:

1234567891011121314151617181920212223242526272829303132333435363738394041
export const StoreProvider = ({ children }: StoreProps) => {
    //...
    const resetCart = async () => {
    deleteCart()

    const savedRegion = getRegion()

    const cartData: {
      region_id?: string,
      sales_channel_id?: string
    } = { region_id: savedRegion?.regionId }

    if (process.env.NEXT_PUBLIC_SALES_CHANNEL_ID) {
      //check if customer is b2b
      const { data } = await axios.get(`${MEDUSA_BACKEND_URL}/store/customers/is-b2b`, {
        withCredentials: true
      })

      if (data.is_b2b) {
        cartData.sales_channel_id = process.env.NEXT_PUBLIC_SALES_CHANNEL_ID
      }
    }

    createCart.mutate(
      cartData,
      {
        onSuccess: ({ cart }) => {
          setCart(cart)
          storeCart(cart.id)
          ensureRegion(cart.region)
        },
        onError: (error) => {
          if (process.env.NODE_ENV === "development") {
            console.error(error)
          }
        },
      }
    )
  }
    //...
}

This change is similar to the previous change. It ensures that the correct sales channel ID is assigned to the cart when it’s reset.

Finally, change the Copy to clipboardensureCart function inside Copy to clipboarduseEffect to the following:

1234567891011121314151617181920212223242526272829303132333435363738394041424344454647
useEffect(() => {
    const ensureCart = async () => {
      const cartId = getCart()
      const region = getRegion()

      if (cartId) {
        const cartRes = await medusaClient.carts
          .retrieve(cartId)
          .then(async ({ cart }) => {
            if (process.env.NEXT_PUBLIC_SALES_CHANNEL_ID && cart.sales_channel_id !== process.env.NEXT_PUBLIC_SALES_CHANNEL_ID) {
              //check if b2b customer
              const { data } = await axios.get(`${MEDUSA_BACKEND_URL}/store/customers/is-b2b`, {
                withCredentials: true
              })
              if (data.is_b2b) {
                //update cart's sales channel
                const response = await medusaClient.carts.update(cart.id, {
                  sales_channel_id: process.env.NEXT_PUBLIC_SALES_CHANNEL_ID
                })

                return response.cart
              }
            }
            return cart
          })
          .catch(async (_) => {
            return null
          })

        if (!cartRes || cartRes.completed_at) {
          deleteCart()
          await createNewCart(region?.regionId)
          return
        }

        setCart(cartRes)
        ensureRegion(cartRes.region)
      } else {
        await createNewCart(region?.regionId)
      }
    }

    if (!IS_SERVER && !cart?.id) {
      ensureCart()
    }
    // eslint-disable-next-line react-hooks/exhaustive-deps
  }, [])

Similar to the previous changes, this ensures that when the storefront is opened and the cart is retrieved, the correct sales channel is assigned to the cart.

Change the Nav Component

To ensure customers can access the wholesale login page, you’ll add a new link to the navigation bar.

In Copy to clipboardsrc/modules/layout/templates/nav/index.tsx add the following in the returned JSX above the Account link:

123456
<Link href="/wholesale/account">
    <a>Wholesale Account</a>
</Link>
<Link href="/account">
  <a>Account</a>
</Link>

The login page should display a login form for the customer.

To create the login form, create the file Copy to clipboardsrc/modules/wholesale/components/login/index.tsx with the following content:

12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667686970717273747576777879808182838485868788
import { FieldValues, useForm } from "react-hook-form"
import { MEDUSA_BACKEND_URL, medusaClient } from "@lib/config"

import Button from "@modules/common/components/button"
import Input from "@modules/common/components/input"
import axios from "axios"
import { useAccount } from "@lib/context/account-context"
import { useCart } from "medusa-react"
import { useRouter } from "next/router"
import { useState } from "react"

interface SignInCredentials extends FieldValues {
  email: string
  password: string
}

const Login = () => {
  const { refetchCustomer, is_b2b } = useAccount()
  const [authError, setAuthError] = useState<string | undefined>(undefined)
  const router = useRouter()
  const { cart, updateCart } = useCart()

  const handleError = (_e: Error) => {
    setAuthError("Invalid email or password")
  }

  const {
    register,
    handleSubmit,
    formState: { errors },
  } = useForm<SignInCredentials>()

  const onSubmit = handleSubmit(async (credentials) => {
    medusaClient.auth
      .authenticate(credentials)
      .then(async () => {
        refetchCustomer()
        if (process.env.NEXT_PUBLIC_SALES_CHANNEL_ID && cart?.sales_channel_id !== process.env.NEXT_PUBLIC_SALES_CHANNEL_ID) {
          const { data } = await axios.get(`${MEDUSA_BACKEND_URL}/store/customers/is-b2b`, {
            withCredentials: true
          })
          if (data.is_b2b) {
            updateCart.mutate({
              sales_channel_id: process.env.NEXT_PUBLIC_SALES_CHANNEL_ID
            })
          }
        }
        router.push(is_b2b ? "/wholesale/account" : "/account")
      })
      .catch(handleError)
  })

  return (
    <div className="max-w-sm w-full flex flex-col items-center">
      <h1 className="text-large-semi uppercase mb-6">Welcome back</h1>
      <p className="text-center text-base-regular text-gray-700 mb-8">
        Sign in to your wholesale account
      </p>
      <form className="w-full" onSubmit={onSubmit}>
        <div className="flex flex-col w-full gap-y-2">
          <Input
            label="Email"
            {...register("email", { required: "Email is required" })}
            autoComplete="email"
            errors={errors}
          />
          <Input
            label="Password"
            {...register("password", { required: "Password is required" })}
            type="password"
            autoComplete="current-password"
            errors={errors}
          />
        </div>
        {authError && (
          <div>
            <span className="text-rose-500 w-full text-small-regular">
              These credentials do not match our records
            </span>
          </div>
        )}
        <Button className="mt-6">Enter</Button>
      </form>
    </div>
  )
}

export default Login

This login form shows the customer the fields Copy to clipboardemail and Copy to clipboardpassword. When the customer submits the form and they’re authenticated successfully, you check if the customer is a B2B customer and accordingly update the cart’s sales channel ID.

This is important as products can only be added to a cart that belongs to the same sales channel.

The login template component will be displayed on the Login page.

Create the file Copy to clipboardsrc/modules/wholesale/templates/login-template.tsx with the following content:

123456789101112131415161718192021222324
import Login from "../components/login"
import { useAccount } from "@lib/context/account-context"
import { useEffect } from "react"
import { useRouter } from "next/router"

const WholesaleLoginTemplate = () => {
  const { customer, retrievingCustomer, is_b2b } = useAccount()

  const router = useRouter()

  useEffect(() => {
    if (!retrievingCustomer && customer ) {
      router.push(is_b2b ? "/wholesale/account" : "/account")
    }
  }, [customer, retrievingCustomer, router, is_b2b])

  return (
    <div className="w-full flex justify-center py-24">
      <Login />
    </div>
  )
}

export default WholesaleLoginTemplate

In this template, you first check if the customer is already logged in and redirect them to their account page based on whether they’re a B2B customer or not.

If the customer is not logged in, you show the Copy to clipboardLogin form component.

Create the file Copy to clipboardsrc/pages/wholesale/account/login.tsx with the following content:

12345678910111213141516171819
import Head from "@modules/common/components/head"
import Layout from "@modules/layout/templates"
import LoginTemplate from "@modules/wholesale/templates/login-template"
import { NextPageWithLayout } from "types/global"

const Login: NextPageWithLayout = () => {
  return (
    <>
      <Head title="Sign in" description="Sign in to your Wholesale account." />
      <LoginTemplate />
    </>
  )
}

Login.getLayout = (page) => {
  return <Layout>{page}</Layout>
}

export default Login

This is the login page that the customer sees when they access the Copy to clipboard/wholesale/account/login path. It shows the Copy to clipboardLoginTemplate component.

Add Wholesale Account Page

The last part you’ll add to finish the Wholesale login functionality is the account page for wholesalers. This page is shown when the B2B customer is logged in.

Create the file Copy to clipboardsrc/pages/wholesale/account/index.tsx with the following content:

12345678910111213141516171819202122232425262728293031323334
import AccountLayout from "@modules/account/templates/account-layout"
import Head from "@modules/common/components/head"
import Layout from "@modules/layout/templates"
import { NextPageWithLayout } from "types/global"
import OverviewTemplate from "@modules/account/templates/overview-template"
import { ReactElement } from "react"
import { useAccount } from "@lib/context/account-context"
import { useRouter } from "next/router"

const Account: NextPageWithLayout = () => {
  const { customer, is_b2b } = useAccount()
  const router = useRouter()

  if (customer && !is_b2b) {
    router.push("/account")
  }

  return (
    <>
      <Head title="Wholesale Account" description="Overview of your account activity." />
      <OverviewTemplate />
    </>
  )
}

Account.getLayout = (page: ReactElement) => {
  return (
    <Layout>
      <AccountLayout>{page}</AccountLayout>
    </Layout>
  )
}

export default Account

In this page, you first check whether the customer is logged in but they’re not a B2B customer. In that case, you redirect them to the Copy to clipboard/account page which is used by other types of customers.

On this page, you show the same Copy to clipboardOverviewTemplate that is shown by default for customers. This is for the simplicity of the tutorial. If you want to display other information to B2B customers, you can make the changes on this page.

Make sure the Medusa server you created in part 1 is running. Then, run the following command to run the Next.js storefront:

1
npm run dev

Open the storefront at Copy to clipboardlocalhost:8000 and click on the Wholesale Account link in the navigation bar. This will open the login page you created.

In part 1 you created a customer in a B2B customer group. Use the email and password of that customer to log in.

Once you’re logged in, you’ll be redirected to the Copy to clipboard/wholesale/account page.

Create B2B Products Page

In this section, you’ll customize the current product page (available on the page Copy to clipboard/store) to show products as a list of variants in a table. This makes it easier for B2B customers to view available products and their variants and add big quantities of them to the cart.

Change ProductContext

Another context that the Next.js storefront defines is the Copy to clipboardProductContext which manages a product’s options, price, variants, and more.

You’ll be customizing this context to expose in the context the Copy to clipboardsetQuantity function that allows setting the quantity to be added to the cart.

In Copy to clipboardsrc/lib/context/product-context.tsx, add in the Copy to clipboardProductContext interface the Copy to clipboardsetQuantity function:

1234
interface ProductContext {
  //...
  setQuantity: (quantity: number) => void
}

Then, add the function to the object passed to the Copy to clipboardProductActionContext.Provider's Copy to clipboardvalue prop:

12345678910
return (
    <ProductActionContext.Provider
      value={{
        //...
        setQuantity
      }}
    >
      {children}
    </ProductActionContext.Provider>
  )

Please note that the function is already defined in the context with the Copy to clipboardquantity state variable.

Create ProductActions Component

The Copy to clipboardProductActions component is a component that displays a button and a quantity input and handles the add-to-cart functionality. It’ll be displayed for each variant in the products table.

Create the file Copy to clipboardsrc/modules/wholesale/components/product-actions/index.tsx with the following content:

123456789101112131415161718192021222324252627282930313233343536373839
import { Product, Variant } from "types/medusa"
import React, { useEffect, useMemo, useState } from "react"

import Button from "@modules/common/components/button"
import { isEqual } from "lodash"
import { useProductActions } from "@lib/context/product-context"

type ProductActionsProps = {
  product: Product
  selectedVariant: Variant
}

const ProductActions: React.FC<ProductActionsProps> = ({ product, selectedVariant }) => {
  const { updateOptions, addToCart, inStock, options, quantity, setQuantity } =
    useProductActions()

  useEffect(() => {
    const tempOptions: Record<string, string> = {}
    for (const option of selectedVariant.options) {
      tempOptions[option.option_id] = option.value
    }

    if (!isEqual(tempOptions, options)) {
      updateOptions(tempOptions)
    }
  }, [selectedVariant.options, options])

  return (
    <div className="flex flex-col gap-y-2">
      <input type="number" min="1" max={selectedVariant.inventory_quantity} value={quantity} disabled={!inStock}
        onChange={(e) => setQuantity(parseInt(e.target.value))} className="border p-2 w-max mt-2" />
      <Button onClick={addToCart} className="w-max my-2">
        {!inStock ? "Out of stock" : "Add to cart"}
      </Button>
    </div>
  )
}

export default ProductActions

This component uses the Copy to clipboarduseProductActions hook which exposes the values in the Copy to clipboardProductContext. In Copy to clipboarduseEffect, it preselects the options in the current variant.

It displays a quantity input and an add-to-cart button. Both the value of the quantity input and the add-to-cart handler are managed by Copy to clipboardProductContext.

Create ProductPrice Component

The Copy to clipboardProductPrice component handles showing the correct variant price to the customer. It’ll be used to show the price of variants in the products table.

This component uses the Copy to clipboarduseProductPrice hook which makes it easier to manage the price of a variant, then display the price to the customer.

Create Products Component

The Copy to clipboardProducts component is the products table that will be shown to the B2B customer.

Create the file Copy to clipboardsrc/modules/wholesale/components/products/index.tsx with the following content:

export default Products

This component retrieves the products in the B2B Sales Channel and displays them in a table. It also shows pagination controls to move between different pages.

For each product, you loop over its variants and display them one by one in different rows. For each variant, you use the Copy to clipboardProductActions and the Copy to clipboardProductPrice components you created to show the quantity input, the add to cart button, and the variant’s price.

Change Store Page

Currently, the store page displays products in an infinite-scroll mode for all customers. You’ll change it to display the Products table for B2B customers, and the infinite-scroll mode for other customers.

Change the content of Copy to clipboardsrc/pages/store.tsx to the following:

12345678910111213141516171819202122232425262728293031323334353637383940414243

import Products from "@modules/wholesale/components/products"
import RefinementList from "@modules/store/components/refinement-list"
import { StoreGetProductsParams } from "@medusajs/medusa"
import { useAccount } from "@lib/context/account-context"
import { useState } from "react"

const Store: NextPageWithLayout = () => {
  const [params, setParams] = useState<StoreGetProductsParams>({})
  const { is_b2b } = useAccount()

  return (
    <>
      {!is_b2b && (
        <>
          <Head title="Store" description="Explore all of our products." />
          <div className="flex flex-col small:flex-row small:items-start py-6">
            <RefinementList refinementList={params} setRefinementList={setParams} />
            <InfiniteProducts params={params} />
          </div>
        </>
      )}
      {is_b2b && (
        <>
          <Head title="Wholesale Products" description="Explore all of our products." />
          <div className="flex flex-col small:flex-row small:items-start py-6">
            <Products params={{
              ...params,
              sales_channel_id: [process.env.NEXT_PUBLIC_SALES_CHANNEL_ID || ""]
            }} />
          </div>
        </>
      )}
    </>
  )
}

Store.getLayout = (page) => <Layout>{page}</Layout>

export default Store

You first retrieve Copy to clipboardis_b2b from Copy to clipboarduseAccount. Then, if Copy to clipboardis_b2b is false, you display the Copy to clipboardInfiniteProducts component. Otherwise, for B2B customers, you display the Copy to clipboardProducts component that you created.

When you hover over the Store link in the navigation bar, it currently shows a dropdown with some products and collections. As this is distracting for B2B customers, you’ll remove it for them.

In Copy to clipboardsrc/modules/layout/components/dropdown-menu/index.tsx, retrieve the Copy to clipboardis_b2b variable from the Copy to clipboardAccountContext:

1234567
import { useAccount } from "@lib/context/account-context"
//...

const DropdownMenu = () => {
    const { is_b2b } = useAccount()
    //...
}

And change the returned JSX to the following:

123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113

If Copy to clipboardis_b2b is true, the dropdown is hidden. Otherwise, Copy to clipboardis_b2b is shown.

Test Products Page

Make sure your Medusa server is still running and restart your Next.js storefront.

Then, open the Next.js storefront and, after logging in as a B2B customer, click on the Store link in the navigation bar at the top left. You’ll see your list of product variants in a table.

Notice how the prices of the variants are different than those shown to other customers. These prices are the prices you defined in the B2B Price List.

You can also test the prices with quantity-based conditions you added to the Price List. For example, if the condition was that product Medusa Hoodie’s variant S should have a different price if its quantity in the cart is more than 10, try changing the quantity to 10 or more and clicking Add to Cart. You’ll see a different price for that variant in the cart.

Test Checkout Flow

The checkout flow is pretty similar to those of regular customers:

Add a couple of items to the cart from the table.
Click on the My Bag link at the top right of the navigation bar.
Click on Go to Checkout.
Fill out the Shipping Address information and choose a Fulfillment method.
Choose a payment method. Since in this tutorial you didn’t add any payment methods, you’ll use the manual payment method. However, you can integrate many other payment methods with Medusa such as Stripe or PayPal, or create your own.
Click on the Checkout button.

This places the order on the Medusa server. Please note that Medusa does not capture the payment when an order is placed; it only authorizes it. You’ll need to capture it from the Medusa admin.

View Order Details on Medusa Admin

Run both the Medusa server and Medusa admin you created in part 1. Then, access the Medusa admin on Copy to clipboardlocalhost:7000.

After logging in, you should see the list of orders in your store. In the list, you can see the payment status of the order, the sales channel, and more.

You should find the order you just created in the list. Click on the order to view its details.

On the order details page, you can see all the details of the order such as the items ordered, the payment and fulfillment details, the customer’s details, and more.

Capture Payment

To capture the payment of the order:

Scroll to the Payment section.
Click on the Capture Payment.

If you chose the Test payment provider during checkout, this will not actually do anything other than change the payment status of the order. If you’re using other payment providers such as Stripe, this is when the payment will actually be captured.

Conclusion

By following this two-part tutorial series, you should have the basis of a B2B ecommerce store built with Medusa. You can perform much more customizations and add additional features to your store including:

Add a payment provider. As mentioned, you can add payment providers like Stripe and PayPal, or create your own.
Create a Fulfillment Provider.
Integrate search engines such as Algolia or MeiliSearch.
