Create or upload documents
Invoices, received documents, and receipts stay separated but ready for one monthly handoff.
Invoices, receipts, and accountant-ready evidence
Monthly accountant package without chaos
OnlineOffice helps freelancers and small businesses collect issued invoices, received documents, receipts, and bank movements into a clear monthly package for the accountant.
Evidence instead of month-end chasing
See which invoices, receipts, and received documents are ready and what is still missing before accountant handoff.
Invoices and documents in one flow
Save issuing companies, customers, PDF/XML/UBL outputs, received documents, bank movements, and exports.
Built for Slovak business reality
Slovak invoice fields, audit trail, malware scanning, backups, and clear PEPPOL/eInvoice readiness boundaries.
How the monthly package gets ready
OnlineOffice is not another file folder. It is a short workflow that shows what is ready for the accountant and what still needs to be completed.
Add bank movements
Movements are matched to invoices or documents so payment and missing-evidence status is visible.
See the month status
OnlineOffice shows ready items, missing receipts, and documents that still need review.
Hand over the package
A monthly ZIP, checklist CSV, and audit trail replace chaotic email threads.
For the business owner and the accountant
The value is not just the invoice. It is a calmer month-end: less chasing, fewer unclear items, and a clear evidence export.
Why it works
- The accountant can see what is ready and what is still missing.
- The business owner does not need to search for receipts in the car, wallet, or inbox.
- PDF, XML, UBL/eInvoice, and attachments stay connected to the document.
