For many entrepreneurs, national e-invoicing was their first forced contact with digitalisation: an obligation handed down by the tax authority, with deadlines, fines and a portal that does not forgive. But two years after it became mandatory, the companies that treated it as a simple box to tick are left with the same inefficient processes, plus one extra step. Those that used the moment to reorganise their workflows gained time, money and peace of mind. Here is how to join the second group.
What e-invoicing means, in brief
Romania's national e-invoicing system (RO e-Factura) requires companies to submit invoices in a structured electronic format (XML, the UBL standard) through the tax authority's virtual private space, within 5 calendar days of issue. The main rules in force in 2026:
- It applies to B2B and B2G transactions on Romanian territory, and since 2025 to B2C as well.
- An invoice becomes fiscally valid only after validation in the system; the PDF sent by e-mail is merely a copy.
- Failure to submit, or late submission, is penalised with fines depending on the taxpayer category.
- Received invoices must be downloaded from the system, not awaited by e-mail.
SAF-T (D406): the bigger brother
The SAF-T declaration (Standard Audit File for Tax) is a detailed XML file that contains practically the company's entire accounting: journals, ledgers, stock, assets. It is mandatory for all taxpayer categories, including small ones, and is filed monthly or quarterly depending on the VAT period. Where e-invoicing targets transactions, SAF-T targets the entire accounting structure – which means data must be clean at source, not corrected at month-end.
The three levels of digitalisation
From our experience with clients, companies sit at one of the stages below:
Level 1 – Minimum compliance. Invoices are issued in an invoicing program with a “send to e-invoicing” button. The accountant files SAF-T from their own data. It works, but information travels on paper and e-mail, and errors are discovered late.
Level 2 – Integrated workflows. Invoicing, stock and accounting sit in the same system or are integrated. An order from the online shop automatically generates the invoice, the invoice goes to the e-invoicing system, the payment is reconciled automatically with the bank statement. SAF-T comes out of the system without reprocessing.
Level 3 – Digital company. On top of level 2: CRM for customers, electronic signatures for contracts, digital archive, dashboards with real-time indicators, automations (payment reminders, contract renewals). The manager sees the state of the company from a phone, not from last month's report.
Most SMEs are at level 1 and should be at level 2. The cost difference is smaller than most people think.
Which software you need
| Need | Common solutions | Indicative cost |
|---|---|---|
| Invoicing with e-invoicing | SmartBill, FGO, Oblio, Saga | 5-30 EUR / month |
| Stock + invoicing + accounting | SME ERP, Odoo | 2,000-8,000 EUR implementation |
| Online shop – invoicing integration | WooCommerce/Shopify – invoicing connector | 100-400 EUR set-up |
| Electronic signature | Qualified certificate | 30-60 EUR / year |
| Electronic archiving | Cloud with EU backup | 5-20 EUR / month |
The concrete steps to reach level 2
- Map your workflows. Where orders come from, who issues invoices, who collects payment, who sends things to the accountant. Draw them on a sheet of paper; you will immediately see where work is duplicated.
- Choose a pivot system. Either the ERP or the invoicing program becomes the “source of truth”. Everything else integrates with it.
- Connect the website and the online shop. Orders must reach the system without manual re-entry. It is one of the most frequent integrations we build in our IT division.
- Automate e-invoicing in both directions. Automatic submission after validation, automatic download of supplier invoices.
- Give the accountant direct access. No folders, no spreadsheets. Clean data at source means SAF-T without reprocessing and without corrections.
- Train the team and set a single rule: what is not in the system does not exist.
What you gain, concretely
For a distribution client we measured the effects three months after integration: invoicing time dropped from 3 hours to 20 minutes per day, stock errors disappeared, and payments arrived on average 9 days sooner thanks to automatic reminders. The total investment was recovered in under a year.
Funding for digitalisation
Software, IT equipment, electronic signatures and digitalisation consulting are eligible expenses in the EU and national funding programmes open in 2026. We covered them in detail in our EU funding guide. A well-structured digitalisation project can be financed at 70-90%.
How we help
Our Digital Transformation service starts with a 2-3 day process audit and ends with systems implemented, integrated and the team trained. If you only need the website integrated with invoicing, or a bespoke system, the calculator gives you an immediate estimate, and the team replies within the same working day.
E-invoicing was not designed to make your life easier. But it can be used for exactly that purpose, if you treat it as a starting point rather than a destination.
