B2B Platform for Wholesalers: Off-the-Shelf or Custom?

Your wholesale customers order the way they did ten years ago: by email and phone. Sales reps retype orders into the ERP, mixing up product codes along the way, and the buyer waits until the next day for a confirmation. Meanwhile, your competitors give their customers a panel with individual prices and stock levels, available around the clock. A B2B platform for wholesalers has stopped being a gadget - increasingly, it is the price of keeping your customers. The practical question remains: subscribe to an off-the-shelf platform or build a custom one?

What a B2B platform for wholesalers must include

A B2B panel is not "an online store for companies". Wholesale has its own rules, and four of them are non-negotiable:

• Individual price lists - every buyer sees their own prices and discounts, negotiated with their sales rep, not a public price list.
• Credit limits - control of trade credit and overdue payments before an order enters fulfilment.
• Reordering from history in three clicks - wholesale is repeat buying; the customer wants to repeat the last order and adjust quantities, not browse a catalogue.
• ERP and warehouse integration - stock, prices and documents must flow automatically from systems such as Comarch Optima, Subiekt or enova, the ERPs common in Poland. A panel without integration creates a second, manual job instead of removing one.

Off-the-shelf platforms: when they are enough

Subscription B2B platforms make sense when your process is standard: a catalogue without complex variants, discount-group pricing, one warehouse, typical documents. You get a fast start and a predictable monthly cost. The limits are well known too: fees grow with users or turnover, a non-standard process has to be bent to fit the system, and ready-made ERP connectors are often shallow - they sync products but will not carry your discount or reservation logic. We wrote about comparing the two approaches honestly in off-the-shelf system or custom software.

When a custom platform earns its keep

A custom B2B platform wins where your competitive edge lives in a process no off-the-shelf product will handle:

• Product configurators - made-to-measure products, set assembly, cutting to size: the customer builds an order that used to require a call with a sales rep.
• Non-standard quoting - requests for quotation, negotiations, offers valid for a set number of days, multi-level approvals.
• Multi-warehouse - availability and delivery time calculated per location, transfers between warehouses.
• Margins and terms per customer - pricing policy as an advantage: promotions for selected groups, quantity thresholds, individual logistics terms.

Off-the-shelf or custom - a quick comparison

Roll out in stages: start with an MVP

A custom platform is not built for a year behind closed doors. The sensible path is staged: first an MVP - an ordering panel with individual price lists and stock synchronisation with your ERP, then credit limits, documents and settlements, finally configurators and analytics. The first stage is an investment from PLN 25,000, and every next one closes a specific process - you pay for value you can see. We explain why an MVP is the safest start in our post on building an app MVP, and the traps of connecting to accounting and warehousing in system integration in a company.

How to start the decision

Write down three things: how a wholesale order is taken today, which parts of the process are non-standard, and how many hours a month manual retyping costs you. If the process is typical - trial an off-the-shelf platform. If your advantage lives in the non-standard parts - price a custom one. We build such platforms as part of our e-commerce solutions, working remotely across Poland.
