Frequently Asked Questions

We support a variety of traditional formats, with Word, Excel, and PDF being the most common among our clients. We can also assist with annual reports in HTML format. If you have another format, please contact us to explore the possibilities.

Yes, there are some important points to ensure a correct iXBRL conversion:

Do not use images for tables
Sometimes Excel tables are pasted as images in Word or PDF. This is not allowed because images cannot be tagged and will appear as images in iXBRL. Always paste tables as real tables. If necessary, we can assist you.

PDF must be editable
A scanned PDF cannot be processed. Always provide an editable PDF.

Fonts and colors
Use standard fonts or include non-standard fonts in the pdf. Use colors in the RGB color space.

PDF/A-1a compliance
Ensure your PDF complies with the PDF/A-1a standard.

No hidden characters
Remove hidden characters from the document before submission.

No, as of early 2026, we only convert annual reports to the iXBRL format.
Our goal is to support you as efficiently and cost-effectively as possible in your electronic filing obligation — and iXBRL works best for that.

While we always strive to accommodate your needs flexibly, we recommend requesting and accepting our quote in a timely manner. This allows us to ensure that we can complete the conversion of your annual report on time.

We convert your draft annual report into iXBRL and provide a draft file for review by you and your auditor. We process the comments received in one review round before delivering the final version.

Filing through our service is not mandatory.
You may also choose to file the iXBRL annual report yourself via the Chamber of Commerce website using the upload functionality (authentication and authorization required).
Some auditors also offer their clients the option to electronically file the annual report directly via their own client portal. In that case, you can use the iXBRL file we provide for that route, without us filing on your behalf.

You can share your annual report with us in two ways: via our secure upload portal or by email.

Upload portal
You will receive a personal upload link to our secure portal. This is the most direct and secure way to share your files with us.

Email
If desired, you can also send us your annual report by email. We recommend using encrypted email or a password-protected ZIP file.

Whichever method you choose: data security is our highest priority. We adhere to strict standards to process your information securely and maintain our clients' trust.

Access to sensitive information is strictly limited to staff directly involved in the conversion process.
All team members handling your annual report have signed a confidentiality agreement. They declare that they use information solely within their work responsibilities and do not share it for personal purposes.

They also confirm annually that they — and their close family members — have no (financial) interests in our clients. Any changes in this status must be reported immediately.
This way, we ensure the confidentiality and integrity of your data throughout the entire process.
