What's New in USELY Invoicing & Bookkeeping
1.7
September 15, 2026
E-invoices, end to end: • When you import an e-invoice (XML), the original is now stored with the expense and can be shared at any time. • An imported PDF (including ZUGFeRD) becomes the receipt itself instead of being saved as an image only. • The DATEV receipt package includes the XML original next to the receipt image, so your accountant gets the e-invoice as is. • Smaller improvements and bug fixes.
