Which format for which package
- Moneybird reads the UBL: use the address under External invoices
- SnelStart doesn't read a UBL sales invoice yet, but it does read the PDF: choose "UBL file and PDF as two attachments" or "PDF only", and put [verkoop] in the subject
- Yuki lists PDF as its file format: choose the PDF
- e-Boekhouden.nl, Informer, Exact Online, Twinfield and others: choose what your package reads; we explain it for each package
We keep these instructions up to date using each package's own help pages.
