What trade customers actually need
B2B buyers are not browsing. They are placing a repeat order, checking whether something is in stock, chasing an invoice or getting a price approved before end of month.
The features that matter reflect that:
Company accounts with multiple buyers. Buyers, approvers and account managers under one company, with different permissions and visibility.
Customer specific pricing. Price lists, contract pricing, volume breaks and negotiated rates applied automatically rather than looked up by a rep.
Fast reordering. Order history, saved lists, bulk entry by SKU and CSV upload. A buyer reordering forty lines should not be clicking through a catalogue. Where the ordering interface itself is the priority, that is ecommerce website design work rather than an account or pricing exercise.
Quotes and approvals. Quote requests, negotiated pricing and internal approval steps before an order is submitted.
Payment and credit terms. Net terms, credit limits, purchase order references and invoice visibility.
Minimum order quantities and pack sizes. Enforced at the point of ordering, not corrected afterwards by a person.
Not every business needs all of these. Part of the work is deciding which ones genuinely change how customers order and which are complexity your team will end up maintaining for nothing.
