The verdict in three sentences
A finance director at a 50-person SMB who still ticks off 2,000 to 6,000 bank lines by hand every month loses 3 to 5 days of close time. A bank feed connector (30 to 150 EUR per month) paired with matching rules tailored to your flows reconciles 80 to 95 % of lines automatically. The return on investment lands within 6 to 12 months, and the monthly close moves forward by about 3 days.
Where manual reconciliation time goes
Bank reconciliation is expensive because it mixes repetitive tasks (matching a customer transfer to an invoice) with ambiguous cases (one payment covering five invoices, bank fees deducted, partial credit notes). As long as everything runs through a CSV export and a spreadsheet, the accountant handles both kinds of lines at the same pace.
| Item (50-person SMB, 2026 order of magnitude) | Manual reconciliation | Automated reconciliation |
|---|---|---|
| Bank lines per month | 2,000 to 6,000 | 2,000 to 6,000 |
| Lines matched with no intervention | 0 to 20 % | 80 to 95 % |
| Monthly accounting time | 3 to 5 days | 0.5 to 1 day |
| Monthly close | D+10 to D+15 | D+7 to D+12 |
| Internal cost (loaded, 45 EUR/h) | 1,080 to 1,800 EUR/month | 180 to 360 EUR/month |
| Errors caught late | Frequent at year end | Flagged daily as exceptions |
| Cash visibility | Monthly | Daily |
The gain comes mostly from the "exceptions only" rule: the tool proposes a match, and a human only reviews the 5 to 20 % of lines with a discrepancy.
The three automation levels and their cost
Not every SMB needs custom development. The right level depends on volume, the number of banks and the complexity of business rules (deposits, split payments, payment platforms).
| Level | Scope | 2026 cost (market, order of magnitude) | Target match rate |
|---|---|---|---|
| Native accounting software module | Bank feed + simple rules (amount, label) | 30 to 150 EUR/month | 60 to 75 % |
| Connector + advanced setup | Multi-bank aggregation, per-counterparty rules | 150 to 400 EUR/month + 1,500 to 4,000 EUR setup | 75 to 88 % |
| Custom matching rules | Rules engine, grouped payments, tolerated gaps, ERP API | 4,000 to 12,000 EUR + connector | 85 to 95 % |
| Annual support | Rule tuning, new accounts | 10 to 15 % of the project per year | Keeps the rate |
At Kolonell, a custom matching engine connected to your ERP falls within our custom application grid: simple application at 2.5 to 4 M FCFA (3,810 to 6,100 EUR), medium complexity at 4 to 7 M FCFA (6,100 to 10,670 EUR) when several entities and currencies are involved. Maintenance then runs at 35,000, 75,000 or 120,000 FCFA per month (50, 110 or 180 EUR) depending on the support level.
What to scope before signing
- Bank access: in Europe, aggregation runs on PSD2 open banking (consent renewed every 180 days depending on the bank). Check coverage for each of your banks.
- Business rules: list your 10 most frequent discrepancy cases (FX fees, early payment discounts, Stripe payouts net of fees). These are what lift the rate from 70 to 90 %.
- Audit trail: every automatic match must stay traceable (rule applied, date, user who approved the exception). Your auditor will ask.
- ERP output: direct API posting or import file, tested on a full month before going live.

Claire, finance director of a 50-person manufacturing SMB near Lyon (illustrative case), handles 4,000 lines per month across three banks. Her team spends 4 days on it, about 32 hours at 45 EUR loaded: 1,440 EUR per month. After automation (custom project estimated at 9,000 EUR and a connector at 120 EUR per month), 6 hours of exception handling remain, or 270 EUR. Net monthly saving: 1,440 minus 270 minus 120, so 1,050 EUR. The project pays back in about 9 months, and the close moves from D+12 to D+9.
FAQ
Does automated reconciliation replace the accountant?
No. It handles 80 to 95 % of simple lines and leaves the discrepancies to the accountant, around 100 to 600 lines per month for an SMB of this size. The time freed goes to cash analysis.
How long does implementation take?
Allow 2 to 4 weeks for a configured connector, and 6 to 10 weeks for custom rules, including a full month running in parallel with the old process.
Is my bank data safe?
PSD2-licensed aggregators access accounts read-only. Require EU hosting, data encryption and access logs kept for at least 12 months.
At what volume does the investment make sense?
Below 500 lines per month, the native accounting module is often enough. Above 1,500 lines or 3 banks, custom rules usually pay back in under 12 months.
Can it handle Wave or Orange Money payments from an African subsidiary?
Yes, provided statements are pulled daily via API or export. The 1 % fee taken on each transaction must be modelled as a tolerated-gap rule.
