The verdict in three sentences
A B2B reseller portal costs between 45,000 and 130,000 GBP in London in 2026, depending on credit-line handling, discount complexity and the number of account tiers. The main gain is network loyalty: a reseller who orders self-service, sees their credit balance and tracks deliveries lifts their average order value by 10 to 20 %. The differentiating brick is not the catalog but financial management: authorized credit lines, net terms and automatic blocking on overdraft.
What a reseller portal really bills
Budget concentrates on three zones: reseller account approval, the discount engine and credit-line handling.
| Line item | 2026 range (GBP) | Cost driver |
|---|---|---|
| Reseller accounts + approval | 5,500 - 13,000 | KYC, tiers, documents |
| Negotiated pricing + volume discounts | 10,000 - 27,000 | Number of rules, brackets |
| Credit lines + net terms | 8,000 - 23,000 | Auto-block, due dates |
| Order + delivery tracking | 4,500 - 13,000 | Carriers, tracking |
| ERP / accounting integration | 9,000 - 25,000 | API, reconciliation |
| Reseller dashboards | 3,500 - 10,000 | KPIs, exports |
| UAT + network rollout | 4,500 - 12,000 | Number of resellers |
A solid portal starts at 45,000 GBP; with advanced credit, multi-currency and real-time ERP, it exceeds 120,000 GBP.
Credit lines and self-service: the double effect
Credit management is not just convenience: it secures your credit risk while smoothing orders.
| Mechanism | Before | After portal |
|---|---|---|
| Reseller credit visibility | opaque | real time |
| Block on overdraft | manual, late | automatic |
| Order processing time | 1 - 2 days | immediate |
| Orders outside hours | rare | 25 - 40 % |
| Average order value | baseline | +10 to 20 % |
| Dunning cost | high | -30 to 50 % |
Self-service also transforms the rep: from order-taker to account developer, with alerts on resellers whose activity is falling.
Mini case study
Sarah, sales director of a professional cosmetics brand in London (140 resellers, 2,400 orders/month), rolls out a portal at 85,000 GBP. Before, 30 % of her team's time went to data entry and credit chasing. After, average order value rises from 500 to 570 GBP (+14 %), or +168,000 GBP/month in revenue. Dunning drops 40 %, saving 1.5 admin FTEs. Payback in under 6 months on the order-value effect alone.

FAQ
How does this differ from a standard B2B store?
A reseller portal adds the financial and relational layer: credit lines, net terms, partnership tiers and targets. That is 18,000 to 40,000 GBP more than a plain B2B catalog.
How do you manage credit lines and risk?
Each reseller has a credit ceiling; beyond it, the order is blocked or sent for approval. The portal syncs with accounting for a real-time balance, cutting dunning by 30 to 50 %.
Can we have multiple reseller tiers?
Yes: Silver, Gold, Platinum with distinct grids, discounts, free shipping and terms. Rules are configurable without redevelopment.
How long to roll out the network?
The platform ships in 12 to 18 weeks; resellers are then onboarded in waves over 4 to 8 weeks with short training.
Does the portal handle multi-currency?
Yes, useful for international networks: GBP, EUR, USD and FCFA with configurable rates. Budget 3,500 to 9,000 GBP for this brick.
