The verdict in three sentences
A security company with 650 guards loses contracts not because guards skip their patrols, but because it cannot prove the patrols to the client. A guard tour system with QR checkpoints, a digital daily occurrence log and missed-patrol alerts costs between 2,500,000 and 15,000,000+ FCFA (3,810 to 22,870+ EUR) with Kolonell depending on scope, compared with a per-guard subscription for foreign SaaS tools. Measured gains are fewer client disputes and overtime cut by 15 % thanks to scheduling based on real data.
Why the paper logbook is no longer enough
Clients such as banks, embassies, head offices and warehouses now require patrol reports, whether you operate in Yaoundé, Accra, Nairobi or Johannesburg. When a theft happens at 3 a.m., the client's first question is simple: who walked past the warehouse, and when? With an occurrence book filled in at the end of the shift, the answer is not defensible. The contract is often terminated, or a penalty is deducted from the monthly invoice.
| Field problem | Consequence | Indicative cost (2026 ballpark) |
|---|---|---|
| Patrol not proven after an incident | Penalty or contract termination | USD 500 to 3,500 per month of lost contract |
| Occurrence book filled in afterwards | Report disputed by the client | 4 to 8 hours of dispute handling |
| Undetected absent guard | Post uncovered overnight | Loss and liability risk |
| Poorly tracked overtime | Overstated payroll | 10 to 20 % extra cost on night shifts |
| Manual monthly client reports | 2 to 3 days per supervisor | Delayed invoicing |
How a QR checkpoint patrol system works
Weatherproof QR tags are placed at each checkpoint: gate, car park, plant room, rear fence. The guard scans each point with an entry-level Android phone, and the app records time, GPS position and guard identity. If something is wrong, the guard takes a photo and writes a note in the digital occurrence log. If a point is not scanned within its window, an alert goes to the night supervisor by push notification and SMS.
The client receives a daily or weekly automatic report listing patrols, incidents and photos. A QR tag costs a fraction of a dollar, against several dollars for an NFC tag, which makes rollout across 200 sites affordable.
| Option | Cost (2026 ballpark) | Strengths | Limits |
|---|---|---|---|
| Paper occurrence book | Almost nil | Simple | No defensible proof |
| Electronic touch-probe wands | USD 250 to 500 per reader | Rugged | No real time, manual download |
| Foreign guard tour SaaS | USD 5 to 12 per guard per month | Quick start | 650 guards: USD 3,250 to 7,800 per month |
| Kolonell simple application | 2,500,000 to 4,000,000 FCFA (3,810 to 6,100 EUR) | QR patrols, log, alerts | Scheduling and payroll out of scope |
| Kolonell medium application | 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR) | Plus scheduling, client reports, portal | 10 to 14 weeks |
| Kolonell complex application | 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR) | Plus payroll, invoicing, multi-city | Structural project |
Features to prioritise for a 650-guard company
Start with the core that protects your contracts: QR checkpoints, occurrence log, alerts and client reports. Then add shift scheduling linked to real scans: a guard who clocks in at 6:12 p.m. instead of 6:00 p.m. no longer generates a phantom overtime hour. Finally, a client portal where the customer checks the history directly becomes a sales argument in tenders, where large companies increasingly require digital traceability.
Mini case study
Daniel runs a 650-guard security company. Overtime costs him the equivalent of USD 30,000 a month, mostly on night and weekend shifts. By linking schedules to real scans, he cuts overtime by 15 %, saving about USD 4,500 a month.

Last year he also lost two warehouse contracts worth USD 1,500 a month each after thefts with no proof of patrol, USD 36,000 in annual revenue. With a medium Kolonell application at 7,000,000 FCFA (10,670 EUR) and Standard maintenance at 75,000 FCFA (114 EUR) per month, the investment is recovered in under 3 months from avoided overtime alone. A foreign SaaS at USD 8 per guard would cost him about USD 5,200 every month, indefinitely.
FAQ
What phone do guards need?
An entry-level Android smartphone is enough, roughly USD 75 to 120 in 2026. The app works offline and syncs scans as soon as the network returns.
Can a guard cheat by photographing the QR code?
Each scan also records GPS position and a server-locked timestamp. A scan made more than 50 metres from the checkpoint triggers a verification alert.
How long does it take to equip 200 sites?
Allow 2 to 3 weeks to install tags after go-live, site by site. Training a guard takes less than 30 minutes.
Can the client access reports?
Yes, through an automatic email report or a secure client portal. The client sees patrols, incidents and photos for every night.
What does maintenance cost?
Kolonell maintenance ranges from 35,000 to 120,000 FCFA (53 to 183 EUR) per month depending on service level. Extra modules such as payroll are quoted separately.
