The verdict in three sentences
A London fresh produce wholesaler serving 600 restaurants that receives its orders by text message at night should plan EUR 25,000 to 55,000 (about GBP 21,000 to 47,000) for a B2B ordering portal in 2026. The return on investment comes first from a 70% cut in ordering errors and the elimination of manual data entry, well before any extra revenue. The three non-negotiable features are a daily price list, orders placed by 11 p.m. delivered next day and Direct Debit, on a realistic 4-month timeline.
The real cost of the midnight text message
Before pricing the portal, price the current situation. A chef texting three crates of tomatoes and 2 kg of sea bass at 11:40 p.m. creates manual re-entry, unit errors and credit notes.
| Item (600 customers, 2026 estimate) | Text and phone orders | With portal |
|---|---|---|
| Orders per night | 380 | 380 |
| Entry time per order | 3 min | 0 min (direct integration) |
| Entry hours per month | 480 h | 40 h (checks) |
| Entry cost (EUR 32 fully loaded per hour) | EUR 15,360 per month | EUR 1,280 per month |
| Ordering error rate | 4% | 1.2% |
| Credit notes and returns per month | EUR 6,800 | EUR 2,040 |
| Invoicing delay | D+3 | D+0 |
The drop from 4% to 1.2% errors is the 70% reduction targeted. On these items alone, savings exceed EUR 18,000 a month, which makes a EUR 40,000 portal profitable in under 3 months.
What the budget covers
| Module | 2026 range (EUR, excl. VAT) | Detail |
|---|---|---|
| Catalogue and daily price list | 4,000 to 8,000 | Automatic import of market prices every morning |
| Restaurant accounts and negotiated prices | 4,000 to 9,000 | Per-customer price lists, multi-site groups |
| Quick order and usual lists | 3,000 to 7,000 | Reorder yesterday's list in 2 taps |
| 11 p.m. cut-off and route planning | 3,500 to 8,000 | Deadline, zones, delivery slots |
| Direct Debit and invoicing | 4,000 to 9,000 | Mandates, due dates, reminders, e-invoices |
| ERP or management software integration | 4,500 to 10,000 | Stock, order and invoice sync |
| Mobile PWA and QA | 2,000 to 4,000 | Tests with 20 pilot restaurants |
| Total | 25,000 to 55,000 | 4-month timeline |
The high end corresponds to a legacy ERP without an API, which requires a custom connector. In the UK, plan for Making Tax Digital compatible invoicing; in France the same module covers the e-invoicing mandate that started in September 2026.
B2B payment methods compared
| Method | Unit cost 2026 (estimate) | Best for |
|---|---|---|
| Bacs Direct Debit | EUR 0.25 to 0.40 | Regular restaurants, monthly invoice |
| SEPA B2B Direct Debit (EU customers) | EUR 0.35 to 0.80 | Higher-risk accounts, no refund right |
| Card | 1.2 to 1.8% + EUR 0.25 | New customers, pay at order |
| Faster Payments transfer | EUR 0 to 1 | One-off payments |
| Cheque | EUR 1.50 to 3 handling | To be phased out |
For 600 customers invoiced fortnightly, moving from cheques to Direct Debit saves about EUR 2,500 a year in handling and cuts average payment time by 12 days.

Claire, sales director of a fresh produce wholesaler in London (Park Royal), manages 600 restaurant accounts. She invests EUR 42,000 in the portal. After 6 months, 75% of orders go through the portal: night-time data entry falls from 480 to 160 hours a month, saving EUR 10,240 monthly, and credit notes fall by EUR 4,000. Total gain: about EUR 14,000 a month, a 3-month payback. The two night-shift order clerks move to quality control.
FAQ
How much does a B2B ordering portal for a food wholesaler cost in London?
Plan EUR 25,000 to 55,000 (about GBP 21,000 to 47,000) in 2026 for 600 customers, a daily price list and Direct Debit. Maintenance adds EUR 400 to 900 a month.
Will chefs actually use it?
Yes, if ordering takes under 2 minutes on a phone: the reorder-usual-list feature does most of the work. Adoption typically reaches 50% at 3 months and 75% at 6 months with sales rep support.
How do you handle the 11 p.m. cut-off?
The portal blocks next-day orders after 11 p.m. and offers the following slot. Exceptions remain possible for key accounts, with manual approval.
Is the portal ready for e-invoicing rules?
It should be, especially if you also sell to France, where receiving e-invoices became mandatory in September 2026. Budget EUR 3,000 to 6,000 for connection to an approved platform.
What timeline should we plan?
Four months, including a one-month pilot with 20 restaurants. Launching outside peak season, in January or September, limits risk.
