The verdict in three sentences
Automating the invoicing workflow is budgeted between 10 000 and 32 000 EUR in 2026, OCR and dunning included. The main gain isn't just saved entry time: it's the 15 to 30 % DSO reduction, meaning cash freed up. With e-invoicing becoming standard in 2026, automating is also a compliance move.
What the 2026 budget covers
An automated invoicing workflow chains reception, OCR reading, matching against purchase orders, validation, posting and dunning. Here are 2026 ballparks by scope.
| Scope | Key functions | 2026 price (EUR) | Timeline |
|---|---|---|---|
| Dunning | automatic follow-ups | 10 000 - 14 000 | 3-4 wks |
| Standard | OCR + dunning + reporting | 15 000 - 22 000 | 5-7 wks |
| Complete | OCR + matching + accounting | 23 000 - 32 000 | 8-11 wks |
| E-invoicing | 2026 compliance (Factur-X) | + 5 000 - 10 000 | by ERP |
| Run | monitoring + support | 300 - 800 /mo | ongoing |
The e-invoicing module is added to comply with the 2026 electronic invoicing timeline (Factur-X formats, approved platforms).
Automated steps and DSO gain
Each automated step cuts either processing time or payment delay. 2026 estimates for an SME billing 400 to 800 invoices/month.
| Step | Before | After automation | Impact |
|---|---|---|---|
| Invoice entry (OCR) | 6 min/invoice | 0.5 min | -90 % time |
| PO matching | 4 min/invoice | 0.5 min | -87 % time |
| Day-30 follow-up | manual, irregular | automatic | DSO -8 to -15 % |
| Day-45/60 follow-up | often forgotten | automatic | DSO -7 to -15 % |
| Receivables reporting | 5 h/mo | 0.5 h | 4.5 h saved |
For a company with 900 000 EUR in receivables and a 52-day DSO, a 20 % DSO reduction permanently frees roughly 34 000 EUR of cash.
Mini case study
Sophie, CFO of a 55-person services SME in Bordeaux, processed 600 invoices/month with two people and a 58-day DSO. A Complete project at 23 000 EUR automated OCR, matching and dunning. DSO dropped to 44 days (-24 %), freeing nearly 40 000 EUR of cash, and the team reclaimed 45 h/month. The investment pays back in under a year on time alone, not counting the cash gain.
