Materials inventory and cost of goods for small makers (candles, soap, jewelry, sewing, ceramics …) selling on Etsy, Shopify or at markets — in 5 languages (EN/DE/ES/PT/JA) and your own currency.

• Order import with automatic material deduction, included in $15/month: download your Etsy or Shopify orders CSV and every sold item takes its recipe’s materials out of stock at FIFO cost.
• The import shows what it will do before it does it: new lines, lines already imported (the same file twice adds nothing), cancelled and paid-back Shopify orders left out, items it does not know yet (map once, remembered) and materials that would run short.
• Month and year close: opening stock + purchases − personal use − closing stock = cost of goods sold, the parts behind it to the cent, gross profit after fees per product, saved closes and a CSV for your bookkeeper; the year view lists US Schedule C (Form 1040) 2025 Part III lines 35–42. VAT counted net or gross by your setting.
• Your data stays on your device and works without an account; export everything any time. Pro adds an encrypted cloud backup (locked in your browser with your passphrase) to restore on a second device.

Why monthly: every month you sell, buy materials at new prices and need that month’s cost of goods. Cancel and nothing is deleted — your data stays readable and exportable; imports, saved closes and the cloud backup stop.
