The verdict in three sentences
A food wholesaler in London taking 70% of orders by phone pays roughly EUR 12 per order in keying time, errors and call-backs, versus EUR 2 online. A B2B e-commerce platform with negotiated pricing per customer, ERP sync and quick order by SKU costs EUR 30,000 to 90,000 and ships in 4 to 6 months. With 1,800 active customers, payback is measured in months, provided you plan the customer migration and not just the technology.
What phone ordering really costs
The EUR 12 figure adds up sales assistant time (6 to 8 minutes per call), re-keying into the ERP, SKU errors (2 to 4% of lines), credit notes and out-of-stock call-backs.
| Item | Phone | Online |
|---|---|---|
| Order taking time | 7 min | 0 min (self-service) |
| ERP re-keying | 3 min | Automatic |
| Error rate per line | 2 to 4% | 0.3 to 0.5% |
| Average cost per order | EUR 12 | EUR 2 |
| Ordering window | 6 am to 2 pm | 24/7 |
| Average basket | Baseline | +8 to 15% (suggestions, history) |
For 1,800 customers ordering twice a week on average, about 187,000 orders a year, 70% by phone means 131,000 calls and over EUR 1.5 million in annual handling cost.
B2B platform budget in 2026
| Level | Key features | Budget | Timeline |
|---|---|---|---|
| Core | Catalogue, customer account, customer pricing, quick order by SKU | EUR 30,000 to 45,000 | 4 months |
| Standard | + two-way ERP sync, credit limits and minimum order, history | EUR 45,000 to 65,000 | 5 months |
| Advanced | + mobile app for chefs, suggestions, use-by dates and batches | EUR 65,000 to 90,000 | 6 months |
| Online payment | Card, direct debit, bank transfer, 30-day terms | Included or EUR 3,000 to 6,000 | + 2 weeks |
| Maintenance and hosting | Monitoring, updates, minor changes | EUR 800 to 2,000 per month | Ongoing |
The most underestimated item is ERP synchronisation: customer prices, family discounts, stock per warehouse and delivery status. It often represents 30 to 40% of the budget.
Features that make customers switch
Restaurants, bakeries and canteens order late at night or very early. Three features change behaviour: quick order by SKU or usual list, one-click reorder of last week's order and a clear cut-off time for next-day delivery. A 1% online discount for 3 months speeds up the switch.
| Month after launch | Target online share | Main lever |
|---|---|---|
| 1 | 10% | Activation by sales reps |
| 3 | 25% | 1% online discount |
| 6 | 40% | Usual lists and reorder |
| 9 | 50% | Mobile app |
| 12 | 60% | Targeted follow-up of key accounts |

Thomas, managing director of a fresh produce wholesaler in London, 1,800 customers and 187,000 orders a year. He moves from 30% to 60% online orders in 12 months: 56,000 orders switched × (EUR 12 - EUR 2) = EUR 560,000 in handling costs avoided per year, partly redeployed to prospecting. Investment: standard platform at EUR 60,000 and EUR 18,000 annual maintenance. Even counting only 20% of that gain as real savings (EUR 112,000), payback comes in under 9 months.
FAQ
Are our customers ready to order online?
Most under 45 are, and usual-list ordering wins over the rest. Target 25% at 3 months and 50% at 9 months, keeping the phone for urgent orders.
Can we keep our negotiated prices per customer?
Yes, the platform reads the ERP price lists: net prices, family discounts and minimum orders. It is the core feature, budget EUR 15,000 to 25,000 of integration work.
Which ERP is compatible?
Sage, Microsoft Dynamics, SAP Business One or a food-specific ERP with an API or scheduled exports. Without an API, a file sync every 15 minutes is often enough.
Should we offer card payment?
For new customers without an account, yes: card or direct debit secures the first payment. Account customers keep their 30-day terms.
How long for a pilot?
A pilot with 100 customers and the dry goods catalogue launches in 10 to 12 weeks for EUR 20,000 to 30,000, deductible from the full project.
