The verdict in three sentences
An Amsterdam beverage distributor delivering to 900 shops, cafés and restaurants loses time and sales every day with phone orders: data entry mistakes, stock-outs discovered at loading, poorly tracked customer credit. A B2B ordering app with prices per customer category, capped credit and online payment can be built in 3 to 4 months for 6,100 to 10,670 EUR (4,000,000 to 7,000,000 FCFA) at Kolonell. The return comes mainly from higher order frequency and fewer unpaid invoices, not only from call centre hours saved.
What the app must do in 2026
The typical customer is a corner shop in De Pijp, a brown café in the Jordaan or a hotel bar near Zuidas. Orders are placed on a smartphone, often in the evening after closing. The app must be light, work offline while preparing the basket and speak the trade's language: crates, packs, kegs, bottle deposits (statiegeld).
| Feature | Essential version | Full version | Field impact |
|---|---|---|---|
| Catalogue | 150 to 300 SKUs, photos, price per crate or pack | Promotions by area, recommended products | Order in under 2 minutes |
| Pricing | 3 categories (shop, horeca, wholesaler) | Negotiated prices per customer, volume discounts | No more price errors |
| Trade credit | Credit limit shown per customer | Automatic block above the limit, SMS reminder | Fewer unpaid invoices |
| Payment | Invoice on delivery | iDEAL, SEPA direct debit, invoice at 14 days | Traceable collection |
| Deposits | Manual entry | Tracking of crates, kegs and deposit bottles per customer | Fewer lost containers |
| Delivery | List of the day's orders | Routes optimised by area, photo proof of delivery | 10 to 20% fewer kilometres |
| Field sales reps | Ordering on behalf of the customer | Targets, geolocated visits, dashboard | Sales management |
Budget and options in 2026
2026 order of magnitude for the Dutch market, excluding devices and SMS subscriptions.
| Option | Initial cost | Recurring cost | Timeline | Limitations |
|---|---|---|---|---|
| WhatsApp Business + spreadsheet | 0 to 250 EUR | Heavy manual time | 1 week | No credit, no stock, errors |
| Off-the-shelf order-taking SaaS | 500 to 1,500 EUR setup | 25 to 60 EUR per user per month | 4 to 8 weeks | Generic, weak deposit handling |
| Kolonell, ordering app (medium complexity) | 6,100 to 10,670 EUR (4,000,000 to 7,000,000 FCFA) | Maintenance 50 to 180 EUR per month | 3 to 4 months | Scope must be precisely defined |
| Kolonell, full platform with ERP and advanced routing | 10,670 to 22,870+ EUR (7,000,000 to 15,000,000+ FCFA) | Maintenance 110 to 180 EUR per month | 4 to 6 months | Higher budget |
| Payment fees | None | iDEAL about 0.25 to 0.35 EUR per transaction, SEPA 0.35 to 0.80 EUR | Activation 1 to 2 weeks | Fee on each collection |
Most distributors start with the medium version: customer app on Android, iOS and web, back office, capped credit, iDEAL and SEPA payment, route list. Optimised routing and accounting ERP integration come in a second phase.
Mini case study
Daan, sales director of a beverage distributor in Amsterdam (illustrative persona), has 900 active customers ordering 3 times a month on average with a basket of 130 EUR. His 5-person order desk takes every order by phone. Unpaid invoices amount to 2.5% of revenue.
Calculation: 900 × 3 × 130 = 351,000 EUR of monthly sales. If the app lifts frequency to 3.3 orders a month through reminders and promotions, the gain reaches 35,100 EUR of extra sales per month. At a 12% gross margin, that is about 4,200 EUR of extra margin per month. Bringing unpaid invoices down from 2.5% to 1.5% recovers another 3,500 EUR per month. A 9,000 EUR app pays back in a little over a month at full speed, provided 60% of customers adopt it, which requires a real onboarding plan for the sales reps.

FAQ
Will shop owners really order through an app?
Yes if it is simpler than calling: one-tap reorder, clear prices, instant confirmation. Allow 3 to 6 months to reach 50 to 70% adoption, with sales reps installing the app at the customer's premises during visits.
Do we need a native app or a website?
A progressive web app (PWA) covers both: it installs like an app, weighs under 2 MB and runs on any recent smartphone. Native store apps can be added for about 1,500 to 3,000 EUR.
How do we manage trade credit?
Each customer has a limit, for example 800 EUR, and the app blocks new orders above it until the balance is settled. SMS or WhatsApp reminders go out automatically at 7 and 15 days.
Which payment methods should we offer B2B customers?
iDEAL covers most Dutch businesses for immediate payment, SEPA direct debit suits recurring customers, and invoice at 14 days remains the norm for established accounts. Above 3,000 EUR per order, bank transfer is still offered.
Can the app connect to our accounting software?
Yes, via API or automatic export to Exact Online, AFAS, Twinfield or Odoo. Allow 3 to 6 weeks depending on the quality of existing data.
