The verdict in three sentences
A food plant running 60 internal audits a month on paper loses 25 to 35 hours of re-keying every month and lets half of its corrective actions slip, whether it sits in Dublin or in Lomé. In Dublin, a custom quality audit app built by a local agency costs an estimated 35,000 to 80,000 EUR, while Kolonell builds the same scope for 2,500,000 to 4,000,000 FCFA (3,810 to 6,100 EUR) in 6 to 10 weeks. The return on investment comes less from saved paper than from non-conformities closed on time before a customer, ISO 22000 or FSSC audit.
What the app must do, and what each building block costs
The QHSE manager does not need a full quality ERP. They need to replace the audit binder, the personal camera and the corrective-action spreadsheet with a single tool that works on a tablet on the shop floor, even when Wi-Fi drops in the cold zone.
| Module | Concrete function | Share of budget (2026 ballpark) |
|---|---|---|
| Configurable audit checklists | Questions, scoring, weighting, versions by area (receiving, production, packing) | 20% |
| Offline mobile capture | Answers, time-stamped photos, auditee signature, sync when back online | 25% |
| Corrective action plans | Owner, due date, automatic reminders by email or WhatsApp, proof of closure | 20% |
| Non-conformity dashboard | Compliance rate by area, open NCs, average closing time, trends | 15% |
| PDF reports | Audit report generated at the end of the visit, export for the external auditor | 10% |
| Roles and traceability | Auditors, line supervisors, management, tamper-proof history | 10% |
A simple version (checklists, mobile capture, PDF report) sits at the low end, around 2,500,000 FCFA. Automatic reminders, a multi-site dashboard and fine-grained permissions push it toward 4,000,000 FCFA. Beyond that, for example with an ERP or temperature-sensor integration, the project moves into the medium app category, between 4,000,000 and 7,000,000 FCFA.
Dublin, Lomé, off-the-shelf software: comparing options
Before commissioning a build, compare it with subscription audit software. It deploys quickly but is billed per user and rarely designed for unstable connectivity.
| Option | Upfront cost | Recurring cost | Lead time | Limits |
|---|---|---|---|---|
| Paper + Excel (current state) | 0 | 25 to 35 h of re-keying per month | Immediate | Lost photos, forgotten follow-ups |
| International audit SaaS | 0 to 500,000 FCFA setup | 25 to 60 EUR per user per month (market estimate) | 2 to 4 weeks | Rigid checklists, cost grows with auditors |
| Custom app by Kolonell | 2,500,000 to 4,000,000 FCFA | Maintenance 35,000 to 120,000 FCFA per month | 6 to 10 weeks | Needs a clear specification |
| Dublin agency (market estimate) | 35,000 to 80,000 EUR | 10 to 20% of build per year | 10 to 16 weeks | Budget out of reach for many SMEs |
| Lone local freelancer | 1,000,000 to 2,000,000 FCFA (ballpark) | Variable | 8 to 20 weeks | Dependency on a single person |
With 10 users on a SaaS at 40 EUR per month, the annual bill reaches 4,800 EUR, about 3,150,000 FCFA, every year. The custom app pays for itself from the second year and remains the plant's property.
What to lock down in the specification
Three points prevent bad surprises. First, offline mode: a tablet must be able to record a full 80-question audit with 30 photos without network, then sync without duplicates. Second, photo compression: 30 photos of 4 MB per audit means 7 GB a month for 60 audits, so they must be shrunk to 300 KB on the device. Third, proof of closure: a non-conformity only closes with a photo or document, validated by QHSE, so it holds up in front of a certification auditor.
For hosting, plan a cloud server with daily backups. Maintenance of Kolonell custom web applications covers security updates, backups and small changes under three plans: 35,000, 75,000 or 120,000 FCFA per month.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Afi, QHSE manager at a juice and concentrate plant in Lomé (illustrative scenario), leads 4 internal auditors and 60 audits a month. Each audit currently needs 30 minutes of re-keying and formatting, 30 hours a month. At a loaded cost of 4,000 FCFA per hour, that is 120,000 FCFA a month, 1,440,000 FCFA a year. The app at 3,200,000 FCFA removes most of that re-keying. With Basic maintenance at 35,000 FCFA a month, the net saving reaches 85,000 FCFA a month and the investment is covered in just over 3 years. The real lever lies elsewhere: if the plant avoids losing a single distribution contract after an unfavourable customer audit, the project pays for itself several times over. A Dublin plant facing the same problem with a 50,000 EUR local quote would need a far larger saving to break even.
FAQ
How long does it take to deploy a quality audit app?
Allow 6 to 10 weeks from scoping to production for an app at 2,500,000 to 4,000,000 FCFA. A 2-week pilot on a single area of the plant is strongly recommended before rollout.
Does the app work without internet on the shop floor?
Yes, if offline mode is specified from the start. Answers and photos are stored on the tablet and then synced, and a mid-range Android tablet at around 230 EUR is enough.
Can we reuse our existing ISO 22000 or HACCP checklists?
Yes, current Excel checklists are imported and become configurable templates. The QHSE manager can then add or weight questions without a developer, which removes 100% of change requests for simple checklist edits.
What monthly cost should we expect after delivery?
Plan for cloud hosting, often 15,000 to 40,000 FCFA a month depending on photo volume, plus a maintenance plan between 35,000 and 120,000 FCFA a month. The total stays below a 10-user SaaS subscription.
Who owns the app's code?
The source code and data belong to the plant, and the transfer of rights is written into the contract. You can change provider without losing your audit history.
