The verdict in three sentences
For an FMCG distributor in Lagos or Dubai running 45 field sales reps across 3,000 outlets, a custom order-taking app becomes cheaper than a per-seat SaaS within the first year of use. The budget falls in Kolonell's medium application bracket, 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), for a 3 to 4 month project. Success depends on two technical choices: an offline-first PWA and a reliable ERP sync, with no re-keying at head office.
What the app must do on the street
A rep in Lagos makes 25 to 35 calls a day across Ikeja, Surulere, Oshodi, Yaba and Lekki, often stuck in traffic between two outlets. Mobile data drops inside markets and warehouses, devices are entry-level Android phones bought for USD 80 to 130, and the battery has to last a 10-hour day. In Dubai the network is better, but reps cover Deira, Al Quoz and Sharjah, and the app still has to keep working in basements and loading bays.
The right architecture is a PWA (progressive web app): it installs from the browser without going through the Play Store, stores the catalogue and orders on the device, and syncs as soon as connectivity returns. Updates ship without the rep downloading anything.
| Module | Function | Expected effect |
|---|---|---|
| Offline catalogue | 800 SKUs, compressed images, prices per channel (wholesale, semi-wholesale, retail) | Orders taken with no signal |
| Discounts and promotions | Volume tiers, buy-10-get-1 deals, segment discounts | No more manual pricing errors |
| GPS routes | Daily visit plan, geotagged check-in at the outlet | Proof that visits really happened |
| Customer card | Last 3 orders, outstanding balance, credit limit | Suggested selling and credit control |
| Collections | Cash, bank transfer, POS, mobile wallets such as Opay or Paystack links, SMS receipt | Every payment traced |
| ERP sync | Orders, stock and customers every 15 minutes | Zero re-keying at the office |
| Supervisor dashboard | Visit rate, average basket, stock-outs by zone | Daily team management |
The hardest part is the ERP. Distributors in Lagos and Dubai commonly run Sage, Odoo, SAP Business One or Microsoft Dynamics. If the ERP exposes an API, the connector is direct. If it does not, scheduled file exchanges do the job, slower but robust. This choice must be settled during scoping because it drives 20 to 30 % of the budget.
Custom build or SaaS: the three-year maths
Order-taking SaaS tools sold to distributors in Nigeria and the Gulf charge, as a 2026 order of magnitude, USD 20 to 45 per rep per month. For 45 reps, the monthly bill runs from USD 900 to 2,025, before onboarding fees.
| Item | SaaS low (USD 20) | SaaS high (USD 45) | Kolonell custom build |
|---|---|---|---|
| Setup | USD 1,000 to 3,000 (configuration, order of magnitude) | USD 1,000 to 3,000 | 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR) |
| Monthly cost for 45 reps | USD 900 | USD 2,025 | 75,000 to 120,000 FCFA maintenance (114 to 183 EUR) |
| Annual recurring cost | USD 10,800 | USD 24,300 | 900,000 to 1,440,000 FCFA (1,368 to 2,196 EUR) |
| 3-year total excluding SaaS setup | USD 32,400 | USD 72,900 | 6,700,000 to 11,320,000 FCFA (10,204 to 17,258 EUR) |
| Code and data ownership | No | No | Yes |
| Local discount rules | Vendor dependent | Vendor dependent | Fully tailored |
Hosting for the custom build is quoted separately depending on volume and the chosen provider. Even with it added, the three-year gap stays large. SaaS keeps the edge in two cases: fewer than 10 reps (10 × USD 20 × 36 months = USD 7,200), or a six-month trial before committing.
A realistic 3 to 4 month timeline
| Phase | Duration | Deliverable |
|---|---|---|
| Field scoping | 2 weeks | Ride-alongs with 3 reps, mapping of discounts and credit rules |
| Mock-ups and testing | 2 weeks | Clickable prototype tested by 5 reps |
| Offline PWA development | 5 to 6 weeks | Catalogue, ordering, routes, collections |
| ERP connector | 2 to 3 weeks | Two-way sync |
| Pilot | 2 weeks | 8 reps in one zone, for example Ikeja |
| Roll-out | 1 to 2 weeks | 45 reps trained, supervisors equipped |
That is 14 to 17 weeks. The pilot is not optional: it is what surfaces forgotten discounts, outlets with no address and phones that are too old.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Chinedu, head of sales at a beverage and personal care distributor in Lagos, runs 45 reps and USD 1,200,000 in monthly revenue. Orders are written in paper books, then re-keyed by 3 clerks paid USD 250 a month each, USD 750 in total. Pricing and quantity errors trigger disputes and credit notes worth about 0.3 % of revenue, USD 3,600 a month.
With the app, one clerk stays on for checks: USD 500 saved. Disputes fall by two thirds: USD 2,400 saved. Gross savings reach USD 2,900 a month, or USD 104,400 over three years. On the SaaS side, a mid-range tool at USD 35 per rep would cost USD 1,575 a month, USD 56,700 over three years, forever. The custom build, even at the top of the medium bracket (7,000,000 FCFA, 10,670 EUR) plus Premium maintenance at 120,000 FCFA (183 EUR) a month, pays for itself in roughly four to five months of those savings, and the distributor owns the tool.
FAQ
Does the app really work without a signal?
Yes. Catalogue, customers and orders are stored on the phone, and the app can hold several days of orders before syncing. In field tests, 95 % of orders reach the ERP within 15 minutes of the visit.
Do we need new phones?
Not necessarily. Android 10 or later with 3 GB of RAM is enough. If the fleet must be replaced, budget roughly USD 100 per device as a 2026 order of magnitude, about USD 4,500 for 45 reps.
Can reps collect mobile money payments in the app?
Yes, through the payment providers' merchant APIs. Fees remain those of the provider, typically 1 to 1.5 % in 2026, and each payment is linked to the order and the route.
What does maintenance cost after launch?
Kolonell offers three levels: 35,000, 75,000 or 120,000 FCFA a month (53, 114 or 183 EUR). For 45 reps and an ERP connector, Standard or Premium is the right fit.
Who owns the code and the data?
The distributor, entirely. Data can sit with the hosting provider of your choice, and that line is quoted on request depending on volume.
