The monthly reverse-charge invoice to Apple and Google in three entries, as a PDF in the folder of your choice. For sole proprietors in Germany, with or without a small trade.
Every month the same invoice to Apple and Google, and every time the same fiddling with dates, numbers, and the reverse-charge note: StoreRechnung turns it into three entries. Amount, month, invoice number, save. The date of service (the last day of the month), invoice date, due date, and line text follow on their own, and the number continues from your last invoice. The PDF is a clean A4 invoice with your details, the store's address and VAT ID, and the reverse-charge note. It goes straight into a folder of your choice, for example in iCloud Drive, with names like 2026-09_APPSTORE-10.pdf. If an amount is wrong, you edit the invoice: same number, new PDF, the old file is replaced. During setup, you enter your address, VAT ID or tax number, and the next invoice number once, and see your invoice update live as you type. The details of Apple Distribution International and Google Ireland are included and can be changed. The overview shows your revenue per store and year. Invoices and business details sync between your devices through your own iCloud: no account, no server of ours, no tracking. The app is available in German.
