Two ways to file
Software
or service.
Your call.
Most providers force a choice: hire an expensive conversion bureau every year, or buy clunky software you have to learn yourself. We do both, and let you switch any year. The mapping you build, stays yours.

Mandatory e-filing deadline
From financial year 2025, Dutch e-filing is mandatory for all legal entities. First filings are due in 2026.
What you get
A report that reads like the original and parses like data.
XBRL is the international standard for digital annual reporting: structured financial data that regulators, lenders and analysts can read directly. We produce (i)XBRL output ready for KVK, HMRC or your ESEF regulator from your draft annual report and submit it on your behalf.
Bring what you have
Send us whatever you have.
Most clients send Word or Excel. We also work with HTML, XHTML and PDF. If your report lives somewhere else, just ask — we'll find a way to ingest it.

Integrations
Imports trial balance from your bookkeeping*
No more re-keying balance-sheet rows from a PDF.
*For an additional fee you can connect your accounting platform once and we will pull trial balances, mapping suggestions and prior-year comparatives with updates at the same time as when your book keeper does
Auditor support
Your auditor will have questions.
We'll answer them.
A direct technical line between our registered accountants and your audit team. They get tag-level answers in writing, you stay out of the loop, and revisions during the audit are included at no extra cost.
Edge cases, handled
Group reports.
Foreign GAAP. Article 2:403.
If your filing is anything other than a standalone NL-GAAP report, whether a group annual report, an Article 2:403/408 consent, or a report prepared under IFRS or a foreign standard, we still take it. The taxonomy variant, dimensions and consent declarations are part of the standard service.
Frequently asked questions
Still wondering?
Both — and you can switch any year. Some clients tag year one with our managed service, then take year two and three into the self-serve editor because the mapping is already done. The mapping stays yours regardless.
Today: Dutch KVK (NL-GAAP and IFRS), HMRC XBRL company accounts in the UK, and ESEF for EU-listed entities. Other jurisdictions are added as demand justifies.
From financial year 2025 onwards, Dutch legal entities must file electronically with the Chamber of Commerce. XBRL is the recommended format because it preserves the original layout while embedding machine-readable tags.
Intake, conversion to XBRL, full taxonomy tagging at the level required for the financial year, validation against the SBR Business Register rules, a viewer for your auditor, all revisions during the audit, and direct filing with KVK plus the filing receipt.
Yes. We deliver a viewer that lets the audit team click a number and see the tag concept, period, unit and dimensions. We also answer their technical questions directly — at no extra cost.
Revisions during the audit are included. Re-tagging, re-validating and re-issuing the package happens at no extra charge.
