The verdict in three sentences
An OCR + AI data extraction pipeline costs 12,000-20,000 EUR in 2026, integration with your business software included. A firm frees up 5 to 12 hours of data entry per week and cuts re-keying work by 40%. Accuracy reaches 92 to 98% with a human validation layer on critical fields.
What the budget covers
Extracting data from supplier invoices, contracts or statements requires a chain: scanning, OCR, structured AI extraction, validation, then injection into the business software (Sage, Cegid, a legal DMS). Here is the 2026 breakdown.
| Item | Range (EUR) | Timeline |
|---|---|---|
| OCR + AI extraction pipeline | 8,000 - 16,000 | 4-7 wks |
| Validation and correction interface | 2,000 - 3,000 | 2 wks |
| Business software integration | 4,000 | 2-3 wks |
| Testing and model tuning | 1,000 - 2,000 | 1 wk |
| Project total | 15,000 - 25,000 | 8-12 wks |
The OCR + AI item varies with document diversity. Homogeneous invoices cost less than a mix of multi-page contracts, tables and scans of varying quality.
Cost per page and governance
Beyond the project, each processed page has a marginal cost (model API calls, storage, validation). Here are 2026 orders of magnitude by monthly volume.
| Monthly volume | API cost/page | Human validation | Total cost/page |
|---|---|---|---|
| < 1,000 pages | 0.04 - 0.08 EUR | 0.15 EUR | ~0.20 EUR |
| 1,000 - 5,000 pages | 0.03 - 0.06 EUR | 0.10 EUR | ~0.14 EUR |
| 5,000 - 20,000 pages | 0.02 - 0.04 EUR | 0.06 EUR | ~0.09 EUR |
| > 20,000 pages | 0.01 - 0.03 EUR | 0.04 EUR | ~0.06 EUR |
On governance: EU data hosting, encryption, access logs and retention periods. For a firm, client confidentiality often requires processing in an EU region and a GDPR data-processing agreement.
Mini case study
Sylvie, admin manager at an accounting firm in Lyon (14 staff), processed 2,800 supplier invoices a month by hand. Data entry took 9 hours/week at 30 EUR/hr loaded, i.e. 1,170 EUR/month. After an 18,000 EUR project, entry dropped to 3.5 hours/week (validation only): 455 EUR/month. Monthly saving: 715 EUR, plus the disappearance of VAT errors. ROI is reached in 25 months on data entry alone, cut to 14 months once error and penalty reductions are included.

FAQ
What accuracy can we really expect?
Between 92 and 98% on standard fields (amount, date, number) in 2026. Rare or handwritten fields stay lower, hence the targeted human validation layer.
Do we need high volume for it to pay off?
From 1,000 to 1,500 pages per month, automation becomes worthwhile. Below that, a light iPaaS setup or a pay-per-use SaaS fits better.
Where is sensitive data stored?
For a firm, we favour EU hosting with encryption and a GDPR processing agreement. Some models can run in a private environment where confidentiality demands it.
Can extraction plug into our business software?
Yes: Sage, Cegid, ACD, or a legal DMS via API or structured import. Integration is about 4,000 EUR of the budget.
How much does processing one page cost in production?
Between 0.06 and 0.20 EUR per page depending on volume, human validation included. The higher the volume, the lower the unit cost.
