The verdict in three sentences
For a security company with 600 guards in Dakar, the real purpose of a guard tour app is proof the client cannot dispute: timestamp, geolocation, incident photo. A custom solution costs, as a 2026 order of magnitude, between 4,000,000 and 9,000,000 FCFA (6,100 to 13,720 EUR), plus 2,000 to 8,000 FCFA per NFC checkpoint. It pays for itself as soon as it prevents two or three penalties of 5 to 10% on large contracts.
Why the paper logbook no longer satisfies clients
Clients in Dakar (banks, industrial sites in the Mbao area, Almadies residences, embassies, warehouses at the Autonomous Port) increasingly demand verifiable reporting. A logbook signed at 3 a.m. no longer convinces a security manager who has found a door left open. Recent contracts include penalties of 5 to 10% of the site's monthly invoice for each unmanned post or missed patrol.
A guard tour app answers three questions: did the guard go to the right place, at the right time, and what did they see? Each checkpoint (an NFC tag or QR code fixed to a wall, door or valve) is scanned with the duty smartphone. The app records the time, GPS position, guard identity and, when needed, a photo and a voice note in Wolof or French.
| Control method | Unit cost 2026 | Proof reliability | Limits |
|---|---|---|---|
| Paper logbook | 3,000 FCFA per logbook | Low, easy to falsify | No real-time check |
| Radio call to the control room | Radio 150,000 to 300,000 FCFA per post | Medium | No usable written record |
| Laminated printed QR code | 500 to 1,500 FCFA per point | Good with a photo | Can be photographed and rescanned elsewhere |
| NFC sticker tag | 2,000 to 4,000 FCFA per point | Very good | Requires an NFC-capable phone |
| Rugged anti-vandal NFC tag | 5,000 to 8,000 FCFA per point | Very good | Longer outdoor installation |
| Bluetooth beacon | 10,000 to 20,000 FCFA per point | Excellent, passive detection | Batteries replaced every 1 to 2 years |
For 120 client sites with an average of 8 checkpoints, you need 960 tags. With standard NFC, the hardware budget is around 2,900,000 FCFA (4,420 EUR) including installation, based on an average cost of 3,000 FCFA.
What the app costs in 2026
International guard tour SaaS tools charge 5 to 15 EUR per guard per month. For 600 guards, the annual bill reaches 36,000 to 108,000 EUR (23 to 70 million FCFA), without Wave payments or a Wolof interface. That is what pushes mid-sized companies toward a custom app they own.
| Module | Market range 2026 (order of magnitude) | Timeline |
|---|---|---|
| Guard mobile app (Android, offline mode) | 1,500,000 to 3,000,000 FCFA | 5 to 7 weeks |
| NFC and QR scanning, timestamp, GPS | 500,000 to 1,000,000 FCFA | 2 weeks |
| Incident report with photo and audio | 600,000 to 1,200,000 FCFA | 2 to 3 weeks |
| Shift and relief scheduling | 800,000 to 1,800,000 FCFA | 3 to 4 weeks |
| Client portal with automatic PDF reports | 600,000 to 1,500,000 FCFA | 3 weeks |
| SMS and WhatsApp alerts to supervisors | 300,000 to 600,000 FCFA | 1 week |
| Full project total | 4,000,000 to 9,000,000 FCFA | 3 to 5 months |
Offline mode is essential: in an underground car park or a sheet-metal warehouse, the network drops. The app stores scans locally and syncs them once the connection returns, without losing timestamps. Also budget one entry-level NFC Android phone per post, 60,000 to 90,000 FCFA (90 to 140 EUR) each in 2026.
At Kolonell, a business app of this scope falls under the medium-complexity custom app grid, 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), with Standard maintenance at 75,000 FCFA (110 EUR) per month.
The features that make the difference with clients
The client portal changes the commercial relationship. A bank's security manager receives a PDF report every morning: planned patrols, completed patrols, gaps, incidents with photos. Penalty disputes are settled with data instead of statements.
Three features are often underestimated: the man-down alert (no phone movement for 15 minutes), the silent panic button and shift check-in by geolocated selfie. They protect guards as much as clients and strengthen your bid in tenders.

Mini case study
Illustrative scenario: Moussa, operations director of a 600-guard security company in Dakar, manages 120 sites. His average billing is 1,500,000 FCFA per site per month. In 2025 he paid 14 penalties averaging 7%, that is 14 × 105,000 = 1,470,000 FCFA, and lost a 2,400,000 FCFA per month contract for lack of evidence.
He invests 6,500,000 FCFA in the app, 2,900,000 FCFA in NFC tags and 75,000 FCFA per month in maintenance. If the tool prevents two thirds of penalties (980,000 FCFA) and retains a single contract of similar size (28,800,000 FCFA annual revenue, about 5,700,000 FCFA margin at 20%), the annual gain is close to 6,700,000 FCFA (10,210 EUR). Payback is around 17 months, before counting tender wins.
FAQ
QR code or NFC: which one for patrols in Dakar?
NFC is more reliable, because a QR code can be photographed and rescanned from the guard booth. An NFC tag costs 2,000 to 8,000 FCFA versus 500 to 1,500 FCFA for a laminated QR code. Many companies combine both: NFC for sensitive points, QR for low-risk zones.
Does the app work without internet?
Yes, if it is built offline-first. Scans are stored locally with their timestamp and synced as soon as the network returns, often within 30 seconds.
How long does it take to roll out to 600 guards?
Allow 3 to 5 months of development, then 4 to 6 weeks of rollout in waves of 100 guards. A 2-hour training per team is usually enough if the interface is in French and Wolof.
Can the reporting be billed to clients?
Some companies add an option of 25,000 to 50,000 FCFA per site per month for the client portal and automatic reports. Across 120 sites, this can fund the tool in under two years.
Is guard geolocation a legal issue?
In Senegal, Law 2008-12 on personal data requires informing guards and limiting tracking to working hours. A declaration to the CDP, the data protection authority, is recommended before rollout.
