Invonio vs sevdesk
sevdesk is a full accounting suite with a genuinely free entry tier. Invonio is purpose-built for e-invoicing only — nothing else. Here's how they actually compare.
Quick verdict:
sevdesk's free tier is a fair, low-volume option if you send 3 invoices a month or fewer and don't need bookkeeping yet. Once you outgrow that cap, or want bookkeeping, banking and tax filing in the same product, sevdesk's paid tiers cover more ground than Invonio. Invonio's free tier has no invoice-sending cap at all — issuing your own invoices needs a paid plan at any volume, but receiving, archiving and validating supplier invoices is unlimited and free, and you never pay for accounting features you don't use.

FAQ
Common questions
Not necessarily — if you want bookkeeping, banking and tax filing bundled with your invoicing, sevdesk's scope is a real advantage. Invonio makes sense specifically when you'd rather not pay for that bundle, or when you've outgrown sevdesk's free 3-invoices-a-month cap and don't want to move straight to a full accounting subscription just to keep sending invoices.
Per their public pricing page, the free tier is capped at 3 sent invoices per month — going over that requires upgrading to a paid tier. Invonio's paid tier has no invoice-count cap.
It isn't mentioned on their public pricing or XRechnung pages as of August 2026. That doesn't necessarily mean it's unsupported — check their current site or ask their sales team for the latest answer.
