Backbone vs. ProSaldo.net: invoices and receipts or Austrian bookkeeping?
ProSaldo.net is a classic among Austrian business tools: invoicing, cash-basis accounting, VAT returns (UVA) and FinanzOnline integration in one place. Backbone (formerly Billy) is an invoicing and receipts platform with an AI assistant — focused on getting your invoices written fast, actually paid, and your receipts to your tax advisor in order.
The honest framing: if you want to do your own bookkeeping including UVA, ProSaldo.net gives you the complete Austrian package — Backbone does no bookkeeping, no UVA and has no BMD export. If you mainly want to write professional invoices fast and leave the books to your tax advisor, Backbone gives you more automation for the money.
Why freelancers pick Backbone next to ProSaldo.net
ProSaldo.net is an accounting product with an invoicing module. Backbone puts the invoice at the center — and automates the part that otherwise slips: following up.
- Invoice from one sentence: "Invoice Huber GmbH €2,000 for consulting" — the assistant drafts, you confirm
- Dunning with statutory interest and the €40 flat fee where the law allows — in ProSaldo.net it is manual per open item
- Clean templates (Basic, Minimal) with your logo and accent color, live preview while you write
- §11 UStG mandatory-detail check while you write, notes for the small-business rule and reverse charge
- Compliant for German clients too (§14 UStG) — without a second tool; receipts and statements as a ZIP for your accountant

When ProSaldo.net is the better choice
To be fair: ProSaldo.net is deeply rooted in the Austrian tax system — UVA filing and FinanzOnline integration included, with a 30-day trial. If you do your books entirely yourself, that is a real argument. Backbone does not cover that part: no cash-basis accounting, no UVA filing (a UVA template is coming soon), no BMD export — your accountant gets a ZIP with receipts, invoices, statements and a CSV report.
