The verdict in three sentences
A B2B ordering portal turns every reseller into an autonomous client: they order 24/7 with their negotiated prices, pay on terms (net-30/net-60) and reorder in two clicks. The realistic 2026 budget runs from 25,000 to 70,000 EUR for the portal, plus 8,000 to 25,000 EUR to connect your ERP. The return is measurable: -30 to -50 % of calls to sales and an average order value up ~18 %.
Modules and their cost
A B2B portal is built from blocks. You rarely start with everything: the MVP covers catalog, per-client pricing and ordering, the rest comes in phases.
| Module | What it does | 2026 cost |
|---|---|---|
| Multi-user client accounts | Buyer/approver roles per company | 4,000 - 8,000 EUR |
| Catalog + per-client price lists | Contract pricing, volume discounts | 6,000 - 12,000 EUR |
| Ordering + fast reorder (CSV/history) | Reorder in 2 clicks | 5,000 - 10,000 EUR |
| Online quotes (quote-to-order) | Price request, approval, conversion | 4,000 - 9,000 EUR |
| Net-30/net-60 credit + credit limit | Payment on terms, auto-block | 5,000 - 12,000 EUR |
| ERP connector (Sage, SAP B1, Odoo) | Synced stock, prices, orders | 8,000 - 25,000 EUR |
| Invoicing area + reminders | Invoices, credit notes, payment tracking | 3,000 - 7,000 EUR |
MVP vs full platform phasing
Launch fast, measure, extend. Here are two typical scopes and their timelines.
| Scope | Content | Budget | Timeline |
|---|---|---|---|
| MVP | Accounts, catalog, per-client pricing, ordering | 25,000 - 35,000 EUR | 8 - 12 weeks |
| Intermediate | + online quotes + ERP connector | 40,000 - 55,000 EUR | 14 - 18 weeks |
| Full | + net-30, credit limit, invoicing, reminders | 55,000 - 70,000 EUR | 20 - 26 weeks |
The MVP often captures 70 % of the value: resellers move online, the phone frees up. Credit terms and the ERP come in phase 2 once adoption is proven.
Sales-time savings
A salesperson spends huge time keying in orders received by phone, email or fax. The portal absorbs them.

| Credit tracking / reminders | 15 min/client | automated | ~80 % |

Mini case study
Karim, sales director of a building-materials trader in Singapore, manages 180 resellers who each place on average 6 phone orders/month. Each order takes 15 min of a salesperson: 180 x 6 x 15 min = 270 hours/month, i.e. ~1.7 FTE at 3,200 EUR loaded. A 48,000 EUR portal (intermediate with ERP) shifts 75 % of orders online, freeing ~200 hours/month. Annual value of recovered time: ~200 h x 12 x ~20 EUR = ~48,000 EUR/yr. The portal pays back in a little over a year, before even counting the +18 % average order value.
FAQ
What is the difference between a B2B portal and a classic online store? The portal assumes an identified client with contract prices, payment on terms and multi-user accounts. A B2C store shows a single public price and requires immediate payment.
Do we need to connect the ERP from the start? Not necessarily. An MVP can run on CSV export/import. The real-time connector (8,000 to 25,000 EUR) becomes a priority when order volume makes manual sync unsustainable.
How do we manage net-30 payment risk? You cap a credit limit per client, automatically block orders beyond it, and pair automated reminders with credit insurance if needed. The credit-limit module costs 5,000 to 12,000 EUR.
What is punchout? It is a standard that connects your portal to the e-procurement system of your large clients. Useful for key accounts, it adds 6,000 to 15,000 EUR to the project.
How long for a first usable portal? An MVP ships in 8 to 12 weeks. A full platform with ERP, net-30 and invoicing takes 20 to 26 weeks.
