The verdict in three sentences
A 90-employee construction contractor owning 600 items of plant without knowing where they are ends up hiring formwork or a mini excavator that is sitting idle on another site. Plant management software with QR code inventory, tracked transfers between sites and statutory inspection follow-up avoids 15 to 25% of external hire. The market budget is EUR 25,000 to 60,000 (about GBP 21,000 to 51,000 or USD 27,000 to 66,000), and the project usually pays back within the year.
The hidden cost of a poorly tracked fleet
In a structural or masonry contractor running 8 to 12 sites at once across a metropolitan area, equipment moves constantly. The site manager calls the yard, the yard does not know, the project manager hires in. By year end, the external hire bill often exceeds EUR 200,000 while the company's own fleet sits underused.
| Indicator (2026 order of magnitude) | Spreadsheet and phone tracking | Plant software with QR codes |
|---|---|---|
| Utilisation of owned fleet | 45 to 55% | 65 to 75% |
| Avoidable external hire | 15 to 25% of hire budget | under 5% |
| Items lost or not found per year | 2 to 4% of fleet | under 1% |
| Overdue statutory inspections | 10 to 20% of items | 0 to 2% |
| Time to locate an item | 30 to 90 min | 2 min |
| Cost allocation per project | estimated at project end | automatic, to the day |
Statutory inspections are a subject of their own: scaffolding, lifting equipment, MEWPs and plant must be inspected on a regulatory schedule (LOLER and PUWER in the UK, OSHA in the US, equivalent rules across the EU). A lapse exposes the company after an accident and during health and safety inspections.
Functions and cost
Each item gets a durable QR code tag. The storekeeper, foreman or driver scans it when it leaves the yard and when it arrives on site, from a phone. The software therefore always knows the location, condition and the project bearing the cost.
| Module | Function | Market budget 2026 (order of magnitude) |
|---|---|---|
| Inventory and QR tagging | item record, photos, documents | EUR 6,000 to 12,000 |
| Mobile scanning app | check-out, returns, transfers, offline mode | EUR 6,000 to 14,000 |
| Planning and bookings | equipment requests per site, availability | EUR 4,000 to 10,000 |
| Statutory inspections | schedule, alerts, inspector reports | EUR 3,000 to 8,000 |
| Cost allocation per project | internal daily rate, export to job costing | EUR 3,000 to 8,000 |
| Dashboard | utilisation, hire, losses | EUR 3,000 to 8,000 |
| Total project | depending on scope | EUR 25,000 to 60,000 |
Off-the-shelf plant management products cost EUR 8 to 20 per item per year or EUR 40 to 90 per user per month, with limited configuration. Kolonell builds a business application remotely on its custom grid: medium, 4,000,000 to 7,000,000 FCFA (EUR 6,100 to 10,670) for inventory, scanning, transfers and inspections, complex, 7,000,000 to 15,000,000+ FCFA (EUR 10,670 to 22,870+) with planning and accounting link. Maintenance is 35,000, 75,000 or 120,000 FCFA per month (EUR 53, 114 or 183).
Making the rollout work on site
The best software fails if crews do not scan. Three rules matter: a scan in under 5 seconds, an app that works offline in basements, and clear ownership (the site manager confirms arrivals). Tagging 600 items initially takes 4 to 6 days for two people. A one-month pilot on 2 sites lets you adjust before company-wide rollout.

Sophie, finance director of a 90-employee structural contractor, records EUR 240,000 of external hire a year. The software avoids 20%, or EUR 48,000. Small tool losses fall from 3% to 1% of a fleet valued at EUR 900,000, saving EUR 18,000. Site managers save 45 minutes a week of searching: 10 people × 39 hours a year at EUR 50: EUR 19,500. Total gain: EUR 85,500 a year for a market-priced project at EUR 45,000 with EUR 5,000 of annual maintenance, paid back in 7 months.
FAQ
Do QR code tags survive site conditions?
Yes, if you choose polyester labels or engraved metal plates at EUR 1 to 4 each. They withstand concrete, pressure washers and UV for 5 years or more.
Does the app work without signal?
Yes. Scans are stored on the phone and synced as soon as the network returns, which covers basements and poorly served rural areas.
Can we track inspections by third-party bodies?
Yes. Each relevant item carries its last inspection date, the PDF report and an alert 30 days before the due date. An overdue item can be blocked from any check-out.
How long until we are operational?
Allow 3 to 4 months: 6 to 8 weeks of development, 1 week of tagging, a 4-week pilot on 2 sites, then rollout.
Can the software also manage hired-in equipment?
Yes. Hired equipment is logged with its planned return date, which avoids on average 5 to 10 days of unnecessary hire per machine per year.
