The verdict in three sentences
Automating an SME's invoicing workflow costs 10,000 to 28,000 EUR in 2026 for an OCR + matching + dunning setup integrated with the ERP (Sage, Cegid, or a local equivalent). The gain is twofold: cost per invoice cut by six (from 12 to 2 EUR) and days sales outstanding down from 52 to 34 days, meaning markedly better cash flow. With e-invoicing mandates advancing, now is the time to scope the project once and for all.
What the budget covers
Price depends on invoice volume, accounting integrations and the level of automated dunning. Here are the typical line items of a 2026 quote.
| Item | Description | Price 2026 |
|---|---|---|
| OCR + extraction | reading supplier invoices | 3,000 - 7,000 EUR |
| Matching | purchase order / receipt | 2,500 - 6,000 EUR |
| Customer dunning | automated scenarios | 2,000 - 5,000 EUR |
| ERP integration | Sage, Cegid, local ERP | 2,500 - 8,000 EUR |
| Acceptance + training | testing and onboarding | 1,500 - 3,000 EUR |
| Total project | 5-8 weeks | 10,000 - 28,000 EUR |
Maintenance runs 180 to 350 EUR/month to track formats, tax changes and dunning rules.
Before / after: the measured impact
Automation changes not only unit cost but also time freed and cash-flow speed.
| Indicator | Before | After |
|---|---|---|
| Cost per invoice | 12 EUR | 2 EUR |
| Days sales outstanding | 52 days | 34 days |
| Entry hours/month | 95 h | 15 h |
| Entry error rate | 6 % | 0.5 % |
| Manual dunning | yes | automated |
| Monthly close | 6 days | 2 days |
On 1,000 invoices/month, moving from 12 to 2 EUR is a 10,000 EUR monthly saving in processing cost, before the cash-flow gain.

As jurisdictions roll out mandatory e-invoicing in structured formats, a well-designed automated workflow integrates those formats and approved platforms natively, avoiding a rushed and costly compliance scramble.
Mini case study
Thomas, CFO of a 35-person industrial trading SME in Toronto, processed 900 supplier invoices/month at 12 EUR each -- 10,800 EUR monthly processing cost. He invests 19,000 EUR in an OCR + matching + ERP-integration workflow, plus 280 EUR/month maintenance. Cost per invoice falls to 2 EUR (1,800 EUR/month): a 9,000 EUR/month saving before maintenance, 8,720 EUR net. The investment is repaid in 2.2 months, and the 18-day DSO gain frees up working capital.
FAQ
