When a delivery arrives, photograph the invoice, upload the PDF or spreadsheet, or forward the email. ShelfIn reads each line, including item codes, barcodes, cases, pack sizes and costs, and matches it to your Shopify products. It remembers each supplier's items and pack sizes, so the next invoice matches by itself. Check everything on one screen, then confirm: stock is added at the location you choose and unit costs are updated. Nothing changes until you confirm, and you can undo for 7 days.

• Reads PDFs, phone photos, emailed invoices and Excel or CSV files
• Matches lines to your products by saved match, barcode, SKU or name
• Turns cases into units with each supplier's pack sizes
• Updates stock and unit costs only after you confirm, with a 7-day undo
