sevDesk is a bookkeeping suite; Backbone is a back office. sevDesk writes invoices and, in its accounting plans, also does cash-basis accounts (EÜR), profit and loss and the German VAT return via ELSTER. Backbone does no bookkeeping. It ties together time tracking, invoices and quotes, dunning, receipts and bank statements, and hands everything to your accountant in one package. On top sits an AI assistant you talk to, inside Backbone or from Claude and ChatGPT.
The short decision: if you want to do your own bookkeeping in the tool, sevDesk fits. If you bill hours and your accountant does the books, Backbone fits.
In short: the difference
sevDesk starts from bookkeeping, with invoicing as one part of it. Time tracking is an add-on.
Backbone starts from the work: you track hours per client and project, turn them into an invoice, Backbone chases it if it stays unpaid, and matches your receipts to bank transactions. At month end you download a ZIP for your accountant.

Worked example for a freelancer who tracks and bills hours, billed monthly: with sevDesk that is "Rechnung" plus time tracking, €11.90 + €4.90 = €16.80 excl. VAT. With dunning levels and recurring invoices you need "Buchhaltung": €25.90 + €4.90 = €30.80 excl. VAT. Backbone Solo is €19 incl. VAT, about €15.97 net at Germany's 19 % or €15.83 at Austria's 20 %, for 1 user; dunning on a schedule starts with Studio (€29).
When sevDesk is the better fit
- You want classic bookkeeping software that does it all in-house. EÜR, P&L and the VAT return via ELSTER, right from the program. Backbone leaves the books to your accountant.
- Your accountant works with DATEV. sevDesk offers a DATEV/ADDISON interface. Backbone delivers a ZIP of files plus a CSV report.
- You prefer menus and forms to asking an assistant. sevDesk's help agent Sevi answers questions about the program; the work itself you do in the program.
- You don't mind assembling your setup from modules. Time tracking (€4.90) and each extra user (€5.90) are add-ons; dunning levels and recurring invoices start with "Buchhaltung".
- You invoice public authorities today. sevDesk already writes XRechnung; in Backbone it is coming soon.
When Backbone is the better fit
- You'd rather ask than click. Say "Invoice Kinetik for September's hours" and Backbone does it, in the app or right inside Claude, ChatGPT, Gemini or Grok. It asks you before anything is sent.
- You want it to feel light. Hours, invoices, reminders and receipts live in one calm place. Nothing to assemble, no add-ons: time tracking, invoices, dunning and receipts are in every plan.
- The admin should run in the background. From Studio, reminders go out on schedule, with statutory interest for Germany and Austria worked out for you. Receipts find their transactions on their own.
- Your accountant does the books. Then you don't need a bookkeeping suite. You need complete receipts, one clean export, and your evenings back.
- You work as a team. Everyone tracks time in the same place, and your bookkeeper gets their own login.
Switching from sevDesk
There is no direct import from sevDesk. This is how you move over cleanly:
- Old invoices stay in your archive. Download your issued invoices from sevDesk as PDFs and keep them. Germany requires 8 years for invoices (§ 14b(1) UStG, § 147(3) AO), Austria 7 years (§ 132(1) BAO).
- Continue your numbering. In Backbone, set the next invoice number under Settings › Numbering, e.g. RE-2026-0148 if your last one in sevDesk was RE-2026-0147.
- Add your clients. Create clients with billing address, VAT ID and payment terms. You can also ask Backbone AI to do it in the chat.
- Upload receipts and statements. Receipts as PDF or image, statements as PDF or CSV. Backbone reads and matches them.
- Start at the turn of a month. That way each month's paperwork sits in one place.
