B2B e-commerce for wholesale: what you need to get right

Many wholesale businesses still run on email, phone calls and PDF price lists. A buyer emails an order, someone retypes it into the accounting system, and a week later the invoice goes out. It works, but it is slow, error-prone and hard to grow.

A B2B store lets your trade customers order online, at their own prices, whenever suits them. But wholesale buying works very differently from retail, so a standard online store is not enough. Here is what to plan for.

How B2B buying differs from retail

A retail shopper buys a few items, pays by card and leaves. A wholesale buyer is often a business with several staff members, several delivery locations, negotiated prices and an agreement to pay later. They reorder the same products regularly and want to do it quickly.

• Prices differ by customer, and sometimes by quantity.
• Orders are larger and often follow minimums or case packs.
• Payment is frequently on terms, such as net 30, rather than at checkout.
• Buyers may need a quote approved before placing an order.
• Accuracy of stock levels matters more, because one order can clear a shelf.

Wholesale pricing and catalogs

Your platform needs to show each buyer their own prices once they log in, while the public sees retail prices or nothing at all. Look for support for price lists or catalogs assigned to specific customers, volume pricing that drops as quantity rises, and quantity rules such as minimums and case increments.

Shopify, for example, includes B2B catalogs, volume pricing and quantity rules on its standard plans, with limits on how many catalogs you can run. At the time of writing, its higher Shopify Plus tier removes the catalog limit and adds features like deposits and partial payments. Plan details change, so check the current feature list for your plan before you commit.

Company accounts and permissions

In B2B, your customer is a company, not a person. A good setup lets you create a company record with multiple locations and multiple buyers attached, each with appropriate permissions. A purchasing manager might see all locations, while a store manager only orders for their own branch.

Decide early how new trade customers will sign up. Most wholesalers do not want anyone to see trade pricing automatically. A common approach is an application form, a manual approval step, then an invitation to the store.

Quotes, invoicing and payment terms

Large or unusual orders often need a conversation before anyone commits. Look for a quote or draft order feature, where a buyer submits a request, your team adjusts it and the buyer approves. Shopify's B2B tools, for instance, let orders be submitted as drafts for review before they are confirmed.

For payment, support the terms your customers already have. That usually means net payment terms with invoices sent after the order, plus the option to pay by card for buyers who prefer it. Storing a card on file for each company location can speed up repeat orders and invoice payments.

Connecting your ERP and inventory

The real time savings come from integration. If your store, accounting and inventory systems talk to each other, orders flow straight through without retyping. Prices updated in your ERP appear on the store, and stock levels stay accurate across channels.

Some ERPs have ready-made connectors for popular platforms. Others need a custom integration built on their APIs. When scoping this work, list each piece of data that has to move, which direction it moves and how often. Prices might sync nightly, while stock levels and new orders need to move within minutes. Plan for what happens when a sync fails, too, so a missed update is noticed rather than silently ignored.

A typical wholesale integration moves a handful of things:

• Customer accounts, price lists and payment terms from the ERP to the store.
• Stock levels from the ERP or warehouse system to the store.
• New orders from the store to the ERP for fulfilment and invoicing.
• Shipping and invoice status back to the store, so buyers can see it in their account.

Where to start

You do not need everything on day one. Many wholesalers launch with logged-in pricing, quick reordering and invoices on terms, then add quotes and deeper ERP integration once buyers are using the store.

Our honest recommendation: start by mapping how a typical wholesale order moves through your business today, from first email to final payment. That map will tell you which features matter most and which integrations will save the most time.
