How it works

Three Steps. No software to learn.

1

Share

Upload your annual report in Word, Excel, PDF or XHTML - or simply email it. We confirm scope within one business day.

2

Receive

Within 5 business days you get back a validated iXBRL package and a friendly viewer to share with your auditor.

3

File

On your approval, we file with the Dutch Business Register and deliver proof of filing. You're done.

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 (or we build) stays yours.

Self-serve · platform

Tag it yourself in our editor.

For finance teams and accountancy firms who want control. Upload the report, drag-and-tag, validate live, file with one click. The taxonomy walks you through it.

  • Live taxonomy autocomplete and validation
  • Pulled figures from PDF, XLSX, DOCX, CSV
  • Mapping reused next year — tag once, file forever
  • Built-in viewer to share with your auditor

Managed · service

Send the report — we handle the rest.

A registered accountant tags it for you, answers the audit team's questions and files with KVK on your sign-off. The standard for one-off filers and complex group structures.

  • Full tagging by a registered accountant (RA)
  • Free revisions during the audit, included
  • Direct line to your accountant — name and email
  • Optional filing to KVK with proof of receipt

What you get

A report that reads like the original  and parses like data.

iXBRL is the international best practice for digital annual reporting: a presentable document for humans, with structured tags machines can read. We deliver both, plus a viewer so you can verify every tag before filing.

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 — 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.

  • NL-GAAP, IFRS and foreign-standard mappings
  • 2:403 / 2:408 group filings & consent declarations
  • Phased tagging — figures now, block tags next year
For accountancy and advisory firms

One workspace. Every client's filing.

Manage every client filing in one workspace, with progress, due dates and review queues laid out the way a firm actually works.

  • Multi-client portal with role-based access
  • White-label brand on the iXBRL viewer
  • Bulk taxonomy mapping across similar clients
  • Per-partner revenue dashboard and capacity planning

Frequently asked questions

iXBRL, questions answered.

Still wondering? Book a 20-minute call →

Self-serve, managed or a mix?

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.

Do you support filings outside the Netherlands?

Yes. Today: Dutch KVK (NL-GAAP and IFRS), HMRC iXBRL company accounts in the UK, and ESEF for EU-listed entities. Other jurisdictions are added as demand justifies.

Why is iXBRL mandatory now?

From financial year 2025 onwards, Dutch legal entities must file electronically with the Chamber of Commerce. iXBRL is the recommended format because it preserves the original layout while embedding machine-readable tags.

What does the price include?

Intake, conversion to iXBRL, 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.

Will my auditor be comfortable with this?

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.

What if the report changes after we send it?

Revisions during the audit are included. Re-tagging, re-validating and re-issuing the package happens at no extra charge.
