How it sells itself

Buchfink erstellt aus jeder bezahlten Bestellung automatisch eine Rechnung mit lückenloser, fortlaufender Nummer. Bei ganzer oder teilweiser Erstattung entsteht die passende Stornorechnung von selbst. Jede Rechnung enthält die strukturierten Daten der E-Rechnung im ZUGFeRD-Format. Belege lassen sich als ZIP für die Steuerkanzlei exportieren.

Zu jeder Bestellung erstellt Ruth automatisch eine GoBD-konforme Rechnung mit lückenloser, fortlaufender Nummer – dazu Korrekturen und Stornos. Steuerrecht erkennt Ruth automatisch: §14, OSS, Reverse-Charge, EU-B2B, Drittland und Kleinunternehmer §19 – bucht auf die richtigen Konten. Unklare Fälle hält Ruth an statt falsch auszustellen (§14c-Schutz).

Key points

How Shoplist compares apps

Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 14, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
