EU e-invoicing readiness and digital accounting for mid-market companies
EU e-invoicing 2027 is not an IT project — it is an operational change affecting every euro your company invoices. We prepare you ahead of time, without last-minute chaos.
From 1 January 2027, mandatory electronic invoicing for all B2B transactions enters force across multiple EU markets. Companies that do not prepare will face penalties, blocked payments, and operational chaos. What the solution is, why not to delay, and where the typical mistakes are — that is what our digital accounting practice is about.
Digital accounting is not just about meeting regulation. It is about transforming accounting from paper archive into a real-time data flow. Invoices are processed automatically via OCR, payments are matched via API directly from the bank statement, and the monthly close takes hours instead of weeks. Because of that, you can see in real time who owes you what, which orders are profitable, and where money is leaking.
At PTR Group we deliver implementation end-to-end — from auditing the current state, through software selection, data migration, automation setup, to team training. We work with Money S3, Pohoda, OmegaSEnergie, and other regional accounting systems, extending them with an automation layer. The goal: after implementation you have an agenda that is simultaneously cheaper, faster, more accurate, and regulation-compliant.
What you get
OCR processing of received invoices
An invoice arrives by email or post — the system automatically extracts company ID, tax ID, amounts, line items, order number. The accountant only reviews and approves. With 200+ invoices a month you save 30–50 hours of administration and error rate drops below 1 %.
Automated payment matching
The bank statement is pulled via API every day and the system automatically matches payments to invoices and orders. Manual matching — two hours daily for your accountant today — shrinks to handling only the exceptions the system cannot match itself.
Banking API integrations
Direct integration with regional banks (Tatra banka, VÚB, Slovenská sporiteľňa, ČSOB, Komerční banka) via their official APIs. No manual statement downloads, no copying numbers from e-banking into accounting. Real-time cash flow visibility directly in the accounting system.
E-invoicing 2027 ready setup
We implement structured electronic invoices aligned with the upcoming national standard (PEPPOL or national API). After implementation you can send and receive e-invoices in real time, with no paper alternative. Audit-ready documentation in case of tax authority inspection.
Accounting system — migration or upgrade
If your current accounting software cannot handle e-invoicing and API integrations, we propose a migration to a modern system or an upgrade of the existing one. We work with Money S3, Pohoda, Stormware Aviso, OmegaSEnergie, and Helios. Migration without downtime — old and new systems run in parallel until everything stabilises.
Accounting team training
Even the best automation fails if the accountant does not use it. We train your accounting team (internal or external) on the new workflow, document the processes, and stay on as support for the first 60 days after go-live.
How we work
Accounting agenda audit (1–2 weeks)
We map your current state: accounting software, monthly invoice volume, data flows, places with manual intervention. We identify gaps relative to e-invoicing 2027 and propose the order of steps. Output: a short document with ROI estimate (typically 40–60 hours saved per month) and implementation plan.
Implementation & migration (4–8 weeks)
Deployment of OCR, the matching engine, and banking API integrations. If needed, accounting software migration. We run in parallel with the manual process for the first 2–4 weeks until it is clear the automation has equal or better output. Then we switch over.
Stabilisation & e-invoicing readiness (2–4 weeks)
The first 30 days in production require fine-tuning — exceptions, edge cases, regulatory detail. After stabilisation we set up the e-invoicing 2027 configuration so you are ready well in advance, not the day before the deadline. We document everything for audit purposes.

Frequently asked questions
When exactly does e-invoicing become mandatory?+
The current schedule (as of May 2026) assumes mandatory B2B e-invoicing in multiple EU markets from 1 January 2027, with transitional periods of 6–12 months for smaller firms. Details and current legislative status are covered in our standalone e-invoicing 2027 article. We recommend starting implementation no later than Q3 2026 to leave room for tuning.
How much does digital accounting implementation cost?+
Fixed price from €8,000 depending on company size and complexity. Small company (up to 200 invoices monthly, single accounting software) from €8,000. Mid-size company (500–2,000 invoices, multiple systems) from €15,000. For corporations, pricing is by scope. Monthly automation operating costs €200–600.
How long does implementation take?+
Typically 2–3 months from kick-off to a stable production state. Audit 1–2 weeks, implementation 4–8 weeks, stabilisation 2–4 weeks. Our fastest delivery was 6 weeks (simple firm with 100 invoices a month), slowest 4 months (complex multi-entity setup).
Will this replace our accountant?+
No — on the contrary, it makes them more effective. The accountant stops spending time on manual data re-keying and starts doing what adds value: controls, exceptional situations, tax optimisation, communication with authorities. For smaller firms one accountant handles 2× more transactions; for larger firms you can redeploy capacity to more strategic tasks.
Which accounting software do you work with?+
Money S3, Pohoda, Stormware Aviso, OmegaSEnergie, Helios — the most common regional accounting systems. If you have a different system, we evaluate whether integration is possible or whether migration makes sense. For very small firms we recommend cloud solutions (Superfaktura, FlexiBee) which are e-invoicing ready.
If we move to new software, where does our data go?+
Migration is part of the implementation. We export all data from the old system, clean and transform it into the new structure, and import it with full auditability. The old database stays archived for any inspection. No lost data, no downtime — migration runs in parallel with live operations.
