The verdict in three sentences
For a distributor serving 650 garages with 12,000 SKUs, WhatsApp orders are expensive in errors, counter time and sales lost in the evening and on Sundays. A custom B2B webshop at USD 20,000 to 42,000 pays off once those losses are measured, provided it rests on three pillars: search by plate number or OEM reference, negotiated prices per garage account and capped customer credit. A standard Shopify or WooCommerce store cannot handle those three cleanly without heavy development.
What the webshop costs, feature by feature
| Feature | 2026 budget (USD, excl. VAT) | Business impact |
|---|---|---|
| 12,000-SKU catalogue, product pages, photos, fitment | 4,200 to 7,500 | Foundation of search |
| Search by plate, model or OEM reference | 3,300 to 8,300 | Fewer wrong parts |
| Garage accounts, discounts and price lists | 2,500 to 5,000 | No more phone haggling |
| Customer credit, balances and limits | 2,500 to 5,000 | Bad-debt control |
| Paystack or Flutterwave, transfer, cash on delivery | 2,000 to 4,200 | Faster collection |
| Stock sync with the ERP | 3,300 to 7,500 | Reliable availability |
| PWA app for mechanics | 2,200 to 4,300 | Ordering from the workshop |
| Total | 20,000 to 42,000 | Live in 4 months |
The most underestimated item is data: cleaning labels, linking OEM references and cross-brand equivalents often takes 4 to 6 weeks on the distributor's side, in parallel with development.
WhatsApp, standard store or custom build
| Criterion (2026 estimate) | WhatsApp orders | Standard store | Custom B2B webshop |
|---|---|---|---|
| Upfront cost | USD 0 | USD 5,000 to 10,000 | USD 20,000 to 42,000 |
| Yearly cost | 2 dedicated sales staff, about USD 8,000 | USD 1,000 to 2,500 | USD 2,500 to 5,000 maintenance |
| Wrong-part rate | 6 to 10% | 4 to 6% | 1 to 2% |
| Per-garage pricing | Case by case | Difficult | Native |
| Credit and balances | Notebook or Excel | No | Native, with automatic block |
| After-hours orders | Lost | Yes | Yes, with scheduled pickup |
Card and transfer payments through Paystack or Flutterwave cost around 1.5% locally, with caps on large transactions. Cash on delivery stays open for garages without a credit account, with the driver recording collection in the app.
A 4-month timeline
- Month 1: scoping, catalogue import, search and garage account mockups.
- Month 2: catalogue, search and price list development.
- Month 3: customer credit, payments, ERP connection.
- Month 4: pilot with 30 garages, fixes, rollout to all 650 accounts.
The pilot is decisive: it reveals badly linked references before every customer sees them.
Mini case study
Tunde, managing director of an auto parts distributor in Lagos, handles 180 orders a day, 7% of them wrong parts. Each return costs about USD 11 (round-trip delivery, counter time), so 180 x 7% x 11 = USD 139 a day, around USD 42,000 over 305 working days. Cutting errors to 2% brings the loss down to USD 12,000. Annual gain: about USD 30,000, before counting evening sales. For a USD 30,000 webshop, payback comes in roughly 12 months.

FAQ
Is plate-number search possible in Nigeria?
Yes, from a model, engine and year table maintained by the distributor and enriched with a fitment database. Budget USD 3,300 to 8,300 depending on data depth, with an 85 to 95% match rate at launch.
How are different garage prices handled?
Each garage account is tied to a price list or discounts by product family. The garage sees its net price at login, which removes most negotiation calls.
Is customer credit secure?
Limit and balance are checked on every order: above the cap, the order switches to card, transfer or cash on delivery. Automatic reminders usually cut average payment time by 10 to 20 days.
Do we need to replace our current ERP?
In most cases no: syncing stock and orders every 5 to 15 minutes is enough. The connector costs USD 3,300 to 7,500 depending on how open the software is.
What does maintenance cost?
Allow USD 200 to 420 a month for hosting, updates and support, so USD 2,500 to 5,000 a year.
