The verdict in three sentences
An open banking (PSD2) integration for automatic reconciliation costs EUR 5,000 to 20,000 in 2026 depending on the banks connected and matching rules. The payoff is immediate: reconciliation goes from hours to minutes and cash becomes visible in real time. An aggregator (Bridge, Powens) is enough to read accounts; custom work pays off for fine matching rules and deep accounting integration.
Integration costs in 2026
Two items shape the budget: access to banking data (aggregator) and building the reconciliation logic.
| Item | Detail | Price 2026 (EUR) |
|---|---|---|
| Aggregator integration | Account connection, bank OAuth | 5,000 - 10,000 |
| Reconciliation engine | Matching rules, exceptions | 6,000 - 15,000 |
| Full custom | Multi-bank + accounting + cash | 15,000 - 20,000 |
| Aggregator subscription | Per connected account | EUR 15 - 60/account/month |
| Maintenance | Reconnections, API changes | 12-18 %/yr |
The choice between a turnkey aggregator and custom integration depends on transaction volume and the accounting depth you expect.
| Criterion | Aggregator (Bridge, Powens) | Custom |
|---|---|---|
| Setup | fast (days) | weeks |
| Upfront cost | EUR 5,000 - 10,000 | EUR 15,000 - 20,000 |
| Matching rules | standard | fine, business-specific |
| Multi-bank | yes | yes |
| Accounting/ERP link | via connector | native |
| Best for | reading, cash view | full automated reconciliation |
Mini case study
Aminata, head of a 25-person distribution SME in Dakar with a French subsidiary, spends 14 hours/month manually reconciling 900 bank transactions across three accounts. She integrates an aggregator and a reconciliation engine for EUR 12,000 (plus EUR 40/account/month). The auto-match rate reaches 88 %; reconciliation time falls to 2 hours/month (12 hours saved) and cash is viewable every morning. Beyond the time saved (~EUR 4,800/yr loaded), she spots unpaid invoices faster and improves collection. Payback in about two years, accounting reliability included.
FAQ
What does PSD2 actually enable?
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
PSD2 (European open banking) allows, with the customer's consent, secure access to accounts via API. That is what lets aggregators read transactions without sharing banking credentials.
What auto-reconciliation rate can I expect?
A well-tuned engine often reaches 80 to 95 % automatic matching; the rest goes to an exception queue handled manually. The rate depends on the cleanliness of labels and references.
Aggregator or custom development?
An aggregator is enough to read accounts and track cash. Custom pays off for complex reconciliation rules and native integration with accounting or the ERP.
Are bank connections reliable over time?
PSD2 access requires periodic reconnection (consent renewal). Maintenance covers these reconnections and banks' API changes.
Is it compatible with West African banks?
Open banking coverage is more mature in Europe. In West Africa, teams often combine available bank APIs, aggregators and statement imports depending on the banks and mobile money.
