The verdict in three sentences
In 2026, automating supplier-invoice extraction via OCR/AI costs 6,000 to 22,000 EUR as a dedicated project, or 0.2 to 0.5 EUR per invoice as SaaS. Shipped in 4 to 8 weeks, the system reads each invoice, extracts the key data (supplier, amount, VAT, due date) and cuts data-entry time by 60 to 80 %. The project-vs-SaaS choice hinges on one variable: your monthly invoice volume.
What a modern invoice OCR actually does
A 2026 invoice OCR doesn't just read text: it understands the document structure, identifies fields even across varied layouts, and automatically matches the invoice to the right purchase order or supplier. AI handles cases where older OCR failed (partially handwritten invoices, exotic formats).
The gain comes from removing manual entry and reducing errors. The correct-extraction rate generally exceeds 90 to 95 % on standard invoices, with remaining cases flagged for human review.
| Extracted data | 2026 reliability | Manual entry avoided |
|---|---|---|
| Supplier name | 97-99 % | 15-20 s/invoice |
| Net / gross amount | 96-99 % | 20-30 s/invoice |
| VAT rate and amount | 94-98 % | 20-25 s/invoice |
| Date and due date | 95-98 % | 10-15 s/invoice |
| Invoice number | 96-99 % | 10-15 s/invoice |
Dedicated project or SaaS: the volume threshold
The math is simple: SaaS bills per invoice (0.2 to 0.5 EUR), a dedicated project is a fixed cost amortized. Beyond a certain volume, the project becomes cheaper and makes you independent.
| Invoices/month | Annual SaaS cost (0.35 EUR) | Amortized project cost (12,000 EUR/3 yrs) | Better option |
|---|---|---|---|
| 200 | 840 EUR | 4,000 EUR | SaaS |
| 500 | 2,100 EUR | 4,000 EUR | SaaS |
| 1,000 | 4,200 EUR | 4,000 EUR | Break-even |
| 2,000 | 8,400 EUR | 4,000 EUR | Project |
| 4,000 | 16,800 EUR | 4,000 EUR | Project |
Under 800 invoices/month, SaaS remains the best fit; beyond 1,000, a dedicated project becomes profitable and offers full control of the data.

Mini case study
Karim, administrative manager of a 40-employee distribution SME in Lille, processes 1,500 supplier invoices a month entirely by hand, about 30 hours a week split across two people. Kolonell deploys an OCR/AI solution with matching for 16,000 EUR. Measured gain: -75 % of entry time, i.e. 22.5 hours per week freed. At a loaded cost of 26 EUR/hour, annual savings reach about 30,000 EUR. Payback: about 6 months, after which both employees refocus on control and supplier relations.
FAQ
Does the system read every invoice? It handles PDFs, scans and photos with 90 to 95 % reliability on standard invoices. Ambiguous cases are flagged for human validation rather than processed silently.
Dedicated project or SaaS, how to choose? Under 800 invoices/month, SaaS at 0.2-0.5 EUR/invoice is cheapest. Beyond 1,000/month, a dedicated project amortizes and keeps you free of a subscription.
Does it integrate with my accounting? Yes. Extracted data flows into your accounting tool (Pennylane, Sage, QuickBooks) via API, avoiding re-entry and completing the automation chain.
How long to set up? Expect 4 to 8 weeks depending on volume and the diversity of supplier formats. A learning phase on your real invoices improves reliability in the first weeks.
Is there still human control? Yes, but reduced. Humans no longer key data: they validate flagged cases and supervise. This shift from entry to control is what creates the gain.
