The verdict in three sentences
Automating data entry with OCR + intelligent extraction (IDP) costs between 8,000 and 20,000 EUR in 2026 for a dedicated solution, or 0.01 to 0.05 EUR/page via a SaaS API. Accuracy reaches 95 to 99 % depending on document quality. The gain: -80 % entry time and a sharp drop in re-entry errors.
SaaS OCR or dedicated solution: a matter of volume
A SaaS OCR API bills per page: ideal to start and for low-to-medium volumes. A dedicated solution (engine trained on your documents, business rules, accounting integration) costs more to build but becomes cheaper and more accurate at high volume.
| Monthly volume | Recommended solution | 2026 indicative cost |
|---|---|---|
| < 500 pages | SaaS OCR API | 0.02 - 0.05 EUR/page + setup |
| 500 - 2,000 pages | API + extraction workflow | 3,000 - 8,000 EUR setup + usage |
| 2,000 - 8,000 pages | Light dedicated solution | 8,000 - 14,000 EUR |
| > 8,000 pages | Full dedicated solution (IDP) | 14,000 - 20,000 EUR |
| All volumes | Maintenance & models | 150 - 500 EUR/month |
At 5,000 pages/month, an API at 0.03 EUR/page costs 150 EUR/month of usage, but without validation or integration it is just a brick. Value comes from the complete workflow: extraction, checking, purchase-order matching, posting to accounting.
The real gain, item by item
| Document | Manual entry time | After OCR + extraction | Target accuracy |
|---|---|---|---|
| Supplier invoice | 3 - 5 min | 20 - 40 s (validation) | 96 - 99 % |
| Delivery note | 2 - 4 min | 15 - 30 s | 95 - 98 % |
| Expense report | 2 - 3 min | 15 - 25 s | 95 - 98 % |
| Purchase order | 3 - 5 min | 20 - 40 s | 96 - 99 % |
| Statement / contract | 5 - 10 min | 1 - 2 min | 90 - 96 % |
Human validation does not disappear: you move from full entry to checking doubtful cases (low-confidence fields). That is where the 80 % time saving is won.
Mini case study
Nadia is accounting manager at a 60-person construction SME in Lille. Her team processes ~3,500 supplier invoices/month, entered by hand, a combined ~200 hours/month. She invests 13,000 EUR in a light dedicated solution plus 350 EUR/month.
With an 80 % reduction, time drops to ~40 h/month, saving 160 hours/month (~1,920 h/year, ~67,000 EUR at 35 EUR/h). Even valuing only part of that reassigned time, the investment pays back in under 4 months, and entry errors (duplicates, amounts) fall sharply.

FAQ
What accuracy can I expect from OCR in 2026?
95 to 99 % on clean, structured documents like invoices. Handwritten or poor-quality documents lower accuracy, hence the value of a targeted validation step.
SaaS API or dedicated solution?
Below 500-2,000 pages/month, an API at 0.01-0.05 EUR/page is enough. Beyond that, a dedicated solution (8,000-20,000 EUR) becomes more accurate and cheaper at volume.
Do I still have to validate manually?
Yes, but only low-confidence fields, not every document. You move from full entry to exception checking, which explains the 80 % gain.
Does OCR integrate with my accounting software?
Yes, via API or structured files. Posting invoices directly into accounting is part of the workflow and avoids any re-entry.
How long to deploy?
Allow 4 to 8 weeks for a dedicated solution, including training on your documents, checking rules and accounting integration.
