B2B E-commerce Infrastructure — Wholesale, Distributor & Dealer Portals
We'd design a custom commerce platform for your wholesaler, distributor, or dealer network — customer-specific pricing, credit limits, approval flows, multi-buyer accounts, and deep ERP integration.
B2B commerce is not a slightly more complicated version of B2C — it is a different category of system, with a different data model, different user behaviour and different operational risks. In B2C a customer adds to cart, swipes a card, leaves. In B2B a customer sees their own price list, checks their credit limit, picks a payment term, sends the order into an approval workflow, the order is confirmed a week later by senior procurement, the invoice lands on the account, and payment arrives by wire transfer 60 days later. Trying to bend an off-the-shelf B2C platform around this workflow — simulating customer-specific everything through a stack of plugins — blows up both the monthly cost and the maintenance load within a year. So we'd ask B2B clients an honest question on day one: do you run a standard B2C model, or is this genuinely B2B? If the second, the cheap-looking entry price of an off-the-shelf platform turns into the most expensive path over a three-year horizon.
Typical Problems in B2B Commerce Operations
Customers call a sales rep for every order — 'what's the price, is it in stock, when can it ship' — and the phone runs all day, even though 95 percent of those queries can be automated.
Stock changes in the ERP (SAP, NetSuite, Dynamics, Logo, Mikro) and the e-commerce catalogue stays stale; the same SKU shows three different numbers across three systems, customers order items that are actually out of stock.
Customer-specific price lists are managed in spreadsheets — five different dealer tiers, five different lists, seasonal campaigns layered in manually; one mistake leads to a dealer placing orders at the wrong price.
Credit limit and payment-terms data is invisible at order time; the order is placed, the invoice is cut, and only then does the ERP credit check reject it — creating friction between the customer and the operations team.
Field sales reps work outside the system: paper forms, WhatsApp messages, evening Excel data entry — missed entries, lost collections and zero real-time visibility for management.
Our Approach
When we build a B2B platform we'd spend the first week on the data model and customer segmentation, not on code. The real complexity of B2B lives not in the UI but in the relational model behind it: customer types (wholesaler, distributor, dealer, key account), the pricing logic that applies to each type, payment terms, credit limits, visibility rules, multi-buyer relationships (multiple purchasing users within the same buying company), and approval chains. Skipping that clarity and jumping to architecture is the single most reliable way to rewrite the project in month six.
On the architecture side we'd default to headless commerce: the storefront layer (a Next.js customer portal plus a React Native rep app) separated from the commerce API (Medusa.js or a fully custom NestJS / FastAPI backend), with a B2B-aware business-rules engine between them. When a user logs in, the system loads price lists, payment terms, visible products and approval flows dynamically based on who they are and which buying company they belong to. On the ERP side we have reusable adapter patterns for SAP Business One, Oracle NetSuite, Microsoft Dynamics 365 Business Central, and regional Turkish ERPs like Logo Tiger, Mikro Fly and Netsis; stock changes can propagate to the commerce layer within 30 seconds to 2 minutes via webhooks or polling depending on what the ERP supports. Orders would flow into the ERP through an idempotent queue, so a network outage or an ERP downtime window does not lose orders — retry logic handles it. Credit limit and account balance can be fetched from the ERP either at order time or from a TTL-bound cache invalidated on every sale.
For the field side we'd ship a React Native app for the sales rep — visit planning, fast order entry from the customer's own price list, real-time credit limit checks, payment collection (where a mobile POS is in scope), GPS-stamped visit logs and daily performance reports. The customer portal and the rep app share the same backend API: an order entered in the field appears in the customer's portal moments later. B2B infrastructure is the area where our architectural experience under the e-commerce hub is deepest, and reusable design templates can take a mid-size wholesaler or a multi-dealer distributor from kickoff to a production-grade release in roughly 12 to 20 weeks.
Process
ERP Data Model Discovery
We map the existing ERP database, account structure, price list logic, credit regime, multi-warehouse setup and current order flow. The actual state of the ERP is often different from what the client believes it to be, and naming that gap early saves months later.
Customer Segmentation & Pricing
Customer types (wholesaler, distributor, dealer, key account), per-type price lists, visibility rules (who sees what), payment terms and the approval matrix are configured — and all of it remains editable through the admin panel, not hardcoded.
Order Flow & Credit Limit Engine
The order pipeline — credit limit check, payment-term selection, multi-buyer approval chain, idempotent ERP sync, stock reservation, retry logic — is built and load-tested against realistic peak traffic.
Sales-Rep Mobile App
React Native rep app: customer visits, fast order entry, credit and account inquiry, collection, GPS-stamped activity, daily reports. iOS and Android from a single codebase, App Store and Play Store releases handled by us.
Operations Dashboard
Management-level reporting across the organisation: order volume, credit utilisation, dealer performance, rep activity, category-level sales and campaign impact (Metabase plus PostHog). Per-customer margin visibility included where the ERP exposes cost data.

We typically reach for the following — adapted per project to your existing ERP, customer segmentation, and payment requirements.
