For accountants
Your client prepares. You sign off.
Your client sends Sybil every paper, from work and home. She sorts, matches and chases before anything reaches you, and only the Professional side ever does. You receive a closed, complete quarter, ready for your own software.
What you receive each quarter

A closed quarter
Your client closes the quarter once every proof is matched to its payment, then sends it to you in one tap.
The register, as CSV
One line per proof, numbered like the proofs themselves.
Numbered proofs
Each receipt and bill as a PDF, numbered to match its line in the register.
Original e-invoices
Peppol e-invoices as received or sent, in their original UBL format, next to their PDF.
A VAT summary
The quarter totals, with VAT and net amounts labelled in words.
Professional only
Your client keeps business and personal paperwork in one app. The pack sent to you is always Professional only: personal documents never leave their vault.
Before and around the books.
Where Use Sybil sits next to your work and your software.
| Accounting software | Your accountant | Use Sybil | |
|---|---|---|---|
| Who uses it | The bookkeeper | Them, for you | You, the owner |
| Which papers | The company's, once booked | What you remember to send | Every paper you receive, work and home |
| Your personal side | No | At tax-return time | Yes, in its own world, never in the pack |
| Contracts and dates | No | Rarely | Notice dates, renewals, payments to expect (ManCo) |
| Books, VAT, annual accounts | Yes | Yes, and signs | No. Prepares them a complete quarter |
How each line was prepared
- Each value shows where it came from: read by Sybil, confirmed by your client, or verified against the bank.
- Deductibility and VAT follow Belgian rules. Where Sybil could not read something, she asks your client before the quarter closes.
- Sybil gives facts, never advice. The books, the filings and the sign-off stay with you.
Where it arrives
The pack is sent to your document inbox, the address your client sets once in Use Sybil.
