原文外掛簡介
Heute Kleinunternehmer, morgen mit Umsatzsteuer — KleinBooks wächst mit.
KleinBooks brings the German business workflow — Angebot → Rechnung (quote → invoice) — directly into your own WordPress admin. No second tool, no monthly SaaS subscription. Start as a Kleinunternehmer (§19 UStG); when your business passes the €25,000 limit, switch to Regelbesteuerung (standard VAT) with one confirmed click and keep working in the same tool.
Free
Write quotes (Angebote) and convert them to an invoice in one click
Invoices with the German mandatory fields (§14 UStG) and sequential numbers
Clean PDF invoices & quotes in three templates (DIN 5008 layout that fits a window envelope), sent by email
Your own e-mail texts for invoices, quotes and Stornorechnungen — shown and adjustable before every send
Clients, and expenses with categories, recurring costs and receipt upload
Dashboard and a Taxes overview: revenue, expenses, profit and an estimated tax reserve
§19 thresholds (€25,000 previous year / €100,000 current year) with a warning before you reach them
Kleinunternehmer ↔ Regelbesteuerung switch — 19 % / 7 % VAT, net / VAT / gross on invoices and quotes, USt-IdNr, input VAT (Vorsteuer) on expenses and a VAT-owed (USt-Zahllast) overview. Invoices you already issued keep their tax treatment.
Pro
KleinBooks Pro (€69 / year incl. 19% German VAT, i.e. €57.98 net; the VAT follows your country, businesses with a VAT ID pay net; 14-day free trial without credit card that ends automatically) is a separate paid version that adds the bookkeeping side. It is sold by our authorised reseller (Merchant of Record) Freemius, Inc.:
GoBD lock — sent invoices can no longer be changed; corrections go through a proper Stornorechnung (own number) and an optional correction invoice
DATEV export (EXTF, SKR03/SKR04) for your tax advisor
USt-Voranmeldung — your quarterly or monthly VAT return figures (Ist or Soll taxation) with PDF
ZUGFeRD / Factur-X e-invoices — for VAT-registered businesses (issuing becomes mandatory from 2027/2028); Kleinunternehmer are exempt from issuing e-invoices
AfA / Abschreibung — depreciation of assets
The free version is an invoicing tool: sent invoices stay editable. GoBD lock with Storno is part of KleinBooks Pro.
