The verdict in three sentences
A public body that must inventory 18,000 assets across 6 sites ahead of a donor audit cannot rely on spreadsheets and paper forms: gaps with the accounting register would be impossible to justify. A QR code asset inventory app, running offline on a smartphone, lets teams record, photograph, geolocate and reconcile every asset within weeks. At Kolonell, this kind of app ranges from 2,500,000 to 15,000,000+ FCFA (3,810 to 22,870+ EUR) depending on complexity, delivered in 2 to 4 months, with labels and hardware on top.
Why paper inventories fail under audit
Donors and lenders (World Bank, African Development Bank, EU, bilateral agencies) increasingly require proof of physical existence for funded assets: computers, vehicles, furniture, generators, technical equipment. In Kinshasa and in many public agencies elsewhere, inventories are still done on printed sheets, keyed in later at head office, with asset numbers painted on or worn away.
| Indicator (2026 order of magnitude) | Paper inventory | Offline QR app |
|---|---|---|
| Assets recorded per agent per day | 80 to 150 | 300 to 500 |
| Time for 18,000 assets with 10 agents | 12 to 22 field days + 3 weeks of data entry | 4 to 6 field days, data available instantly |
| Data entry error rate | 3 to 6% | under 0.5% |
| Proof of existence for the auditor | signature on a list | time-stamped photo and GPS position |
| Reconciliation with accounting register | manual, over several weeks | automatic, discrepancy list in one click |
| Tracking movements after the audit | rarely updated | transfers and disposals logged |
Time savings matter, but the decisive argument for a finance director is traceability: every line of the audit report links to a photo, a date, an agent and a location.
The full budget: software, labels and fieldwork
QR labels cost 0.25 to 0.70 USD each depending on material: polyester for office furniture, anodised aluminium for vehicles and exposed equipment. For 18,000 assets, plan 4,500 to 12,600 USD in labels, plus a 5 to 10% buffer for losses and new purchases.
| Item | Scope | Budget | Timeline |
|---|---|---|---|
| QR labels | 18,000 assets + 10% buffer | 4,950 to 13,860 USD (2026 order of magnitude) | 3 to 6 weeks to print and deliver |
| Kolonell simple level | offline inventory, QR scan, photo, Excel export | 2,500,000 to 4,000,000 FCFA (3,810 to 6,100 EUR) | about 2 months |
| Kolonell medium level | + register reconciliation, discrepancy list, multi-site, roles | 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR) | 2 to 3 months |
| Kolonell complex level | + depreciation, transfers and disposals, accounting integration, donor dashboards | 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR) | 3 to 4 months |
| Maintenance | fixes, monitoring, backups | 35,000 / 75,000 / 120,000 FCFA a month (53 / 114 / 183 EUR) | ongoing |
| Smartphones, hosting, on-site training | depends on agents and sites | on quote | per schedule |
An entry-level Android smartphone is enough: the camera reads QR codes and GPS records the position. There is no need for industrial handhelds for a one-off inventory.
Rollout method across 6 sites
The sequence that works: import the existing accounting register into the app, even if incomplete, then run a pilot site of 1,000 to 2,000 assets for one week. The pilot exposes poorly defined categories, assets that cannot be labelled and network issues. Then teams of 2 agents per site work in parallel: one labels and scans, the other photographs and records condition (good, worn, out of service).
Offline mode is essential: many administrative buildings have weak or unstable coverage. Data is stored on the phone and synced in the evening over office Wi-Fi. At the end, the app produces three lists for the auditor: assets found and matching, assets found but missing from the register, register assets not found.

Jean-Pierre, finance director of a public body in Kinshasa, must present a certified inventory of 18,000 assets within 4 months. On paper, 10 agents at 120 assets a day need 15 field days, then 3 weeks of data entry: about 35 working days. With the app, 10 agents at 400 assets a day finish in 5 field days, with no re-keying. At a daily agent cost of 40 USD, he saves 30 days x 10 agents x 40 USD = 12,000 USD in labour, roughly the label budget. The biggest effect is an audit-ready discrepancy report with photo evidence. These amounts are estimates to confirm against the body's actual costs.
FAQ
Do agents need an internet connection in the field?
No, the app works fully offline and syncs once a network is available. A phone can store several thousand records with photos before syncing.
Which labels suit vehicles or outdoor equipment?
Anodised aluminium labels, around 0.60 to 0.70 USD each, withstand heat, humidity and abrasion. Polyester at 0.25 to 0.40 USD is enough for office furniture and IT.
Does the app calculate depreciation?
Yes at the complex level, using acquisition date and value imported from the register. Rates per category, for example 33% for IT equipment, are configured to your accounting rules.
Will donor auditors accept the report?
For each asset the report provides a time-stamped photo, a GPS position and the agent's name, which meets proof-of-existence requirements. Final acceptance rests with the auditor, with whom the export format can be agreed in advance.
How many agents need training?
A team of 10 to 12 agents is enough for 18,000 assets on 6 sites. Training takes about 2 hours per agent, on the pilot site.
