Frequently asked questions

Is FirmFlow a real alternative to Karbon?

For small accounting and bookkeeping firms — yes. FirmFlow covers the core Karbon use cases: client management, recurring invoicing, time tracking, document sharing, e-signatures, and team messaging. We do not have advanced workflow automation; Karbon has more there.

How much will I save by switching from Karbon?

Karbon charges €59-€80 per user per month. A 5-person firm pays €295-€400/month or €3,540-€4,800 per year. FirmFlow is €29/month flat for 5 users — €348 per year. That is 90% savings.

Can I move my client data from Karbon to FirmFlow?

Yes. Export contacts, clients, and invoice history from Karbon as CSV files and import to FirmFlow. We provide a step-by-step migration guide. Document files transfer manually.

Does FirmFlow have email integration like Karbon?

Not yet — Karbon email-as-tasks feature is one of its strengths. FirmFlow uses in-platform secure messaging instead. If email triage is critical to your workflow, Karbon may still be a better fit.

Is FirmFlow built for accounting firms specifically?

FirmFlow is built for professional service firms — accounting, law, and consulting. Many of our features (client portal, e-signatures, recurring invoicing, time tracking) directly serve accounting firms. Karbon is more accounting-specific in its workflow tooling.
