Customer-specific B2B pricing is more than a discount field. The storefront must recognize the buyer, select the right price group, apply quantity rules consistently, and keep every other pricing tier private. A short test plan can catch mistakes before an approved dealer places a real order.
1. Define the pricing dimensions
Write down the dimensions that can change a buyer’s price: customer group, item, variant, unit of measure, minimum quantity, effective dates, currency, tax treatment, and shipping rules. Microsoft’s customer price group documentation uses many of these fields explicitly. MightyMerchant documents separate retail and wholesale product prices, shipping prices, order minimums, and quantity-pricing fields.
2. Make buyer assignment explicit
Use a small, named set of price groups and record who owns assignment changes. MightyMerchant describes approved wholesale accounts and account price groups, while Shopify’s B2B storefront example passes buyer context when requesting contextual prices and quantity breaks. The operational lesson is simple: test with the same identity and account context the buyer will actually use.
3. Build a compact test matrix
- Signed out: wholesale prices remain hidden.
- Retail account: retail pricing and minimums apply.
- Approved wholesale account: only its assigned tier appears.
- Second wholesale tier: the same SKU shows the intended alternate price.
- Quantity boundary: test one unit below, at, and above each break.
- Variant boundary: verify every priced size, color, pack, or unit.
- Cart and checkout: line price, discount, shipping, tax, and total remain consistent.
- Expired or future agreement: effective dates behave as expected.
4. Test privacy as well as arithmetic
A correct total is not enough if a buyer can see another group’s pricing. Check product pages, search results, quick-order screens, saved orders, cart pages, emails, and downloadable documents. Repeat the test in a fresh browser session so an administrator’s session does not hide an access problem.
5. Keep a change record
For each pricing change, record the affected group, products, quantity thresholds, start and end dates, approver, and test result. Re-run the compact matrix after catalog imports, pricing-rule changes, and account reassignments. This creates a practical handoff between sales, operations, and the person maintaining the store.
