The verdict in three sentences
A wholesaler delivering to 600 restaurants, hotels and caterers across London that still takes orders through voice notes and calls at 11 pm loses money on every keying error. A B2B ordering platform costs between 40,000 and 100,000 GBP in the London market in 2026, delivered in 10 to 14 weeks, with a realistic target of 70 % fewer order errors. The real gain comes from an "order by 10 pm, delivered next day" rule and controlled payment collection, on delivery or at 15 days.
Why voice notes stop working at 600 customers
The head chef of a Shoreditch hotel sends a 40-second voice note at 11 pm: "the usual, but double cream and no unsalted butter". The next morning at 6 am, the picker has to interpret it, find "the usual" and guess the pack size. At 600 customers, this creates omissions, disputes and credit notes. A platform replaces the voice note with a basket prefilled with the customer's usual products, their negotiated prices and a clear cut-off time.
| Indicator (2026 order of magnitude) | Orders by voice note | B2B ordering platform |
|---|---|---|
| Keying time per order | 6 to 10 minutes | Under 1 minute (entered by the customer) |
| Picking error rate | 8 to 12 % | 2 to 4 % (70 % fewer errors targeted) |
| Disputes and credit notes per month | 40 to 70 | 10 to 20 |
| Order cut-off time | Unclear, up to midnight | 10 pm, next-day delivery |
| Tracking of 15-day receivables | Notebook or spreadsheet | Automatic SMS and WhatsApp reminders |
| Stock visibility for the customer | None | Out-of-stock items hidden in real time |
Platform budget in London
Scope drives price. An 800-SKU catalogue with customer-specific pricing, a mobile app for chefs and a driver interface do not cost the same as a basic order form. The ranges below are 2026 orders of magnitude for the London market. For reference, the same scope in Dakar costs 4,000,000 to 8,000,000 FCFA (about 6,100 to 12,200 EUR).
| Component | Market range (GBP) | Timeline |
|---|---|---|
| Catalogue, customer accounts, negotiated prices | 15,000 to 30,000 | 4 to 5 weeks |
| "Usual order" basket and one-click reorder | 5,000 to 10,000 | 2 weeks |
| Cut-off time, slots and delivery rounds | 6,000 to 15,000 | 2 to 3 weeks |
| Payments: on delivery, 15-day terms, cards and direct debit | 6,000 to 15,000 | 2 to 3 weeks |
| Driver app (signed delivery note, photo) | 5,000 to 15,000 | 2 weeks |
| Integration with stock management software | 3,000 to 15,000 | 1 to 2 weeks |
| Total full platform | 40,000 to 100,000 | 10 to 14 weeks |
For clients in West Africa, Kolonell prices this type of project as a medium-complexity custom application, between 4,000,000 and 7,000,000 FCFA (6,100 to 10,670 EUR), and above 7,000,000 FCFA for complex multi-warehouse projects. Standard maintenance is 75,000 FCFA per month (110 EUR): fixes, backups, security updates and small changes.
15-day credit without losing control
Hotels and caterers rarely pay upfront. The platform must handle a credit limit per customer, automatically block a new order beyond the authorised balance and send reminders at day 15, 20 and 30. Small restaurants pay on delivery, by card or bank transfer, with a receipt generated on the driver's phone. The dashboard shows the total outstanding balance and at-risk customers every morning.
Mini case study
Michael, managing director of a fresh produce and dairy wholesaler in London (illustrative scenario), delivers to 600 foodservice customers. He handles 180 orders a day, 10 % of which contain an error. Each error costs on average 25 GBP (product returned, second driver trip, goodwill gesture), so 450 GBP a day and about 11,700 GBP a month over 26 working days. With a 70,000 GBP platform and the error rate down to 3 %, the monthly cost of errors falls to about 3,510 GBP: 8,190 GBP saved per month. After a maintenance budget of 1,500 GBP a month, the net saving is 6,690 GBP and the investment pays back in about 10 to 11 months, not counting the time freed for the staff member transcribing voice notes.

FAQ
Will chefs really order through an app?
Yes, if ordering takes under a minute and shows their usual products. A target of 60 % of orders placed online after three months is realistic, with the rest still coming by phone and keyed in by the team.
Can we keep WhatsApp as a channel?
Yes. The platform sends the order summary, the payment link and reminders by WhatsApp. Customers keep their habit, but the order is structured.
How much for only 200 customers?
A reduced scope (catalogue, customer pricing, cut-off time, payment on delivery) can start around 25,000 to 40,000 GBP in London, delivered in 6 to 8 weeks.
How do we handle fresh produce prices that change every week?
The team updates prices by file import or directly in the interface. Customers see the new price before confirming, which removes disputes over the invoiced amount.
What does maintenance include?
Monitored hosting, daily backups, fixes, security updates and a monthly allowance of minor changes. Kolonell's Standard plan is 75,000 FCFA per month (110 EUR).
