Billcove

Billcove is a deliberately small invoicing tool sold once for €15 rather than rented monthly. It targets freelancers and German Kleinunternehmer who send a modest number of invoices and resent paying a recurring fee for the privilege. You set up your business details once, then write, number and issue invoices with the fields German small-business rules expect, including the Kleinunternehmer VAT note. There is no client portal, no accounting suite, no expense tracking and no bank reconciliation — the scope stops at producing a correct, professional invoice document and keeping a record of what you have sent. That narrowness is the whole pitch. For a solo operator issuing a handful of invoices a month, a €15 one-off replaces something like €10-20 a month indefinitely, and the maths stops being close after the first quarter. It comes from Kevin Koellen's Focus2Grow studio in Hoyerswerda, which has shipped a family of similarly scoped one-time-purchase tools. The trade-off is real: you will outgrow Billcove if you need recurring billing, multi-currency handling, payment collection or a proper bookkeeping trail, and a one-time purchase means feature development is not funded by your subscription. Judge it as a tidy replacement for an invoice spreadsheet rather than as a rival to full accounting software.
