The verdict in three sentences
A B2B e-commerce platform with negotiated pricing and pro ordering costs between 28,000 and 70,000 EUR in 2026, for 8 to 14 weeks of development. The heart of the project is the per-client pricing engine paired with a multi-buyer approval workflow, turning every account into an autonomous sales channel. The payoff: -35% sales time on order processing and an average B2B basket 5 to 20 times larger than B2C.
The B2B features that drive the quote
Not all features are equal. Here is the 2026 cost per module and what it unlocks on the sales side.
| B2B module | 2026 cost (EUR) | What it unlocks |
|---|---|---|
| Per-client price lists | 6,000 - 14,000 | Negotiated prices, contractual discounts |
| Volume discounts / tiers | 3,000 - 7,000 | Quantity-based degressive pricing |
| Online quoting + conversion | 4,000 - 9,000 | Price request, approval, order |
| Personalised catalogues | 3,000 - 8,000 | Range visible per account/zone |
| Approval workflow | 4,000 - 10,000 | Buyer -> approver -> order |
| Fast reorder / lists | 2,500 - 6,000 | One-click reorder, favourites |
| CRM integration | 4,000 - 11,000 | Accounts, history, opportunities |
A core of quoting + per-client pricing + reorder sits around 32,000 EUR. Adding the approval workflow and CRM integration pushes toward 60,000-70,000 EUR.
Why the B2B basket changes the equation
In B2B, the average basket is structurally high: a pro buyer orders in volume, reorders regularly and commits significant amounts. That is what justifies the investment.
| Metric | Typical B2C | B2B pro |
|---|---|---|
| Average basket 2026 | 45 - 90 EUR | 350 - 1,800 EUR |
| Order frequency | 2-4 /year | 1-4 /month |
| Manual processing cost | low | 8-15 min / order |
| Customer lifetime value | moderate | high, contractual |
| Sensitivity to listed price | high | negotiated price expected |
A basket 5 to 20 times larger means even a marginal gain in conversion or reorder quickly pays back the platform.
Mini case study
Sophie, e-commerce director of a professional hygiene distributor in Amsterdam, serves 210 pro customers. Before the portal, each order took 12 minutes of a sales assistant's time (32 EUR/loaded hour), i.e. 6.40 EUR/order. With 1,800 orders/year, that is 11,520 EUR/year of processing.
The portal automates 70% of orders: a ~8,064 EUR/year saving, on top of a 9% reorder uplift from favourite lists. For a 48,000 EUR investment and 800 EUR/month maintenance, the project pays back in under 3 years on time alone, and far faster once the revenue uplift is included.

FAQ
How much does B2B e-commerce with negotiated pricing cost?
Between 28,000 and 70,000 EUR in 2026. The per-client pricing engine and approval workflow are the most structuring line items.
What sales-time gain should I expect?
Around 35% on order processing, because customers enter their own recurring orders and access their negotiated prices 24/7.
Can multiple buyers be managed per customer account?
Yes, that is the approval workflow: a buyer prepares the order, an approver (purchasing manager) signs off before dispatch, with caps and roles.
Does online quoting replace the sales rep?
No, it frees them. Simple requests convert to orders without intervention; reps focus on negotiations and key accounts.
How much is maintenance?
Between 500 and 1,200 EUR/month depending on traffic and changes, i.e. 6,000 to 14,400 EUR/year, covering security, fixes and minor enhancements.
