Is Backbone an alternative to Runple?

Yes — for freelancers and small businesses whose core is hours, invoices and quotes. Backbone adds dunning with interest, receipts and an AI assistant. If you need inventory and warehousing, Runple is the better fit.

What is the main difference between Backbone and Runple?

Runple is a broad business suite (trading, inventory, finance); Backbone is a focused back office for service businesses. In Backbone an assistant drafts documents from one sentence, and ZUGFeRD e-invoices are included — in return, Backbone deliberately skips inventory and bookkeeping.

Are Backbone invoices compliant in Austria?

Yes. Backbone checks the §11 öUStG / §14 UStG mandatory details while you write and adds the small-business and reverse-charge notes.

Can I try Backbone for free?

Yes — for 7 days. You put a card on file at Stripe, €0.00 is due today, and you can cancel monthly. There is no permanently free plan.

Backbone vs. Runple: focused instead of a business suite

Runple positions itself as broad business software with inventory, warehousing and finance features. Backbone (formerly Billy) takes the opposite path: a focused back office for service businesses — time tracking, invoices, dunning and receipts, with an AI assistant that does much of it on request.

If you need to model stock levels and trading processes, Runple belongs on your list. If you are a service business that mainly bills its work and wants to get paid, Backbone is the faster choice.

Why freelancers pick Backbone over Runple

The broader the suite, the more menus stand between you and a finished invoice. Backbone keeps the path short — from the hour logged to the invoice paid.

Backbone in detail

When Runple is the better choice

To be fair: if you sell physical products with stock management, Runple has features Backbone deliberately lacks — and Runple runs three-stage dunning even on its free plan. For pure service businesses a suite’s breadth is dead weight, and that is exactly where Backbone is faster and simpler.
