The verdict in three sentences
A cement, rebar and roofing sheet trader with 4 depots in Conakry and GNF 25 billion in receivables from resellers can no longer manage customer risk with ledgers and a spreadsheet consolidated on Fridays. Trading management software blocks a sale as soon as a reseller exceeds its credit limit, traces every inter-depot transfer and keeps a till in GNF and USD reconciled every evening. Depending on scope, the project falls in Kolonell's medium range (FCFA 4,000,000 to 7,000,000) or complex range (FCFA 7,000,000 to 15,000,000+), with a 4 to 6 month timeline and the final amount set in the quote.
Where building materials traders lose money in Conakry
Building materials trading in Guinea runs on thin gross margins, often 6 to 12 % on cement and 10 to 18 % on rebar and roofing, with credit extended to hardware stores and contractors driving volume. Losses rarely come from one big default, but from many small leaks.
| Leak | Observed symptom | 2026 order of magnitude impact |
|---|---|---|
| Credit without limits | A reseller keeps collecting goods while 90 days overdue | 2 to 5 % of receivables become uncollectable |
| Stock gaps between depots | Transfers on paper, receipts not checked | 0.5 to 1.5 % of stock a year |
| Multi-currency till | USD receipts converted at a rate that varies by cashier | 1 to 3 % gaps on USD takings |
| Uncontrolled pricing | Discounts granted verbally by sales staff | 1 to 2 margin points lost |
| Late chasing | Overdue list produced once a month | Average payment time 15 to 30 days longer |
| Unreconciled mobile money | Orange Money or MTN MoMo payments matched by hand | Several hours a day of reconciliation |
Functional scope of fit-for-purpose trading software
| Module | Key function | Business rule to configure |
|---|---|---|
| Customers and credit | Limit per reseller, payment schedule, automatic block | Override only by the finance director |
| Sales and collection slips | Quote, order, depot collection slip | Floor price per item and customer category |
| Multi-depot stock | Container receipts, transfers, cycle counts | Transfer confirmed on dispatch and on receipt |
| GNF and USD till | Receipts, daily rate set by management, daily close | Till gap explained before closing |
| Mobile money | Import of Orange Money and MTN MoMo statements, matching | Automatic matching by reference |
| Collections | Aged balance, SMS reminders, payment promises | Escalation at 30, 60 and 90 days |
| Dashboard | Receivables, margin per depot, stock turnover | Mobile access for management |
The software must cope with frequent power and internet cuts: depot entry has to keep working offline and sync when the connection returns. That requirement rules out many purely online tools designed for Europe.
Packaged software or custom build: how to decide
Packaged sales management software deployed by a local integrator costs, as a 2026 order of magnitude, EUR 25 to 60 per user per month, plus setup. It works if your rules are simple. Custom becomes relevant when credit control, the dual-currency till and offline mode are central to the business.
| Criterion | Package with integrator | Kolonell custom build |
|---|---|---|
| Upfront investment | Setup varies by integrator | Medium FCFA 4,000,000 to 7,000,000 or complex FCFA 7,000,000 to 15,000,000+, in the quote |
| Recurring cost | Per-user licences, EUR 25 to 60 a month | Maintenance FCFA 75,000 or 120,000 a month |
| Offline mode at depot | Rarely native | Designed in from day one |
| Blocking credit limit | Often just a warning | Hard block with override workflow |
| GNF and USD till | Depends on package | Daily rate enforced, gaps logged |
| Timeline | 2 to 4 months | 4 to 6 months |
Mini case study
Mr Camara, finance director of a Conakry trader, carries GNF 25 billion in receivables across 420 resellers. Each year, about 4 % of receivables, or GNF 1 billion, end up as losses or debt write-offs.
- With blocking limits and reminders at 30, 60 and 90 days, the target is to bring losses down to 1.5 %, or GNF 375 million.
- Estimated gain: GNF 625 million a year, about EUR 66,000 at an indicative rate of GNF 9,450 per EUR.
- Stock gaps cut from 1 % to 0.4 % on an average stock of GNF 12 billion: a further GNF 72 million.
- Custom cost assumption, top of the complex range: FCFA 15,000,000 (EUR 22,870) plus FCFA 120,000 a month maintenance.

FAQ
Does the software work during internet outages?
Yes, depot terminals record sales, collections and receipts offline, then sync as soon as the connection returns. Credit checks use the last known balance, refreshed at least hourly in normal conditions.
How are USD payments handled?
Management sets a daily rate that cashiers cannot change. Each USD receipt is converted at that rate, and the till close shows GNF and USD balances separately, with any gap above zero requiring an explanation.
Can Orange Money and MTN MoMo be integrated?
Merchant statements are imported and matched to invoices automatically by reference. Depending on API access available from operators in Guinea, direct connection is assessed during discovery and priced in the quote.
How long to bring all 4 depots live?
Allow 4 to 6 months in total, with a pilot depot live by month three or four. The other three follow 2 to 3 weeks apart, each after a full opening stock count.
What does maintenance include?
Kolonell offers FCFA 35,000, 75,000 or 120,000 a month depending on level, covering fixes, backups and support. For 4 depots and a multi-currency till, Standard or Premium is recommended.
