Shops that sell loose or cut goods work the arithmetic out by hand on every sale. MiMi does it at the till instead. Staff open the app from a POS tile or from the product itself, type what the scale or tape reads, and the measured amount goes straight into the Shopify POS cart. Tap the container a customer brought and its weight comes off first. Stock moves in decimals, so 12.35 kg is still right after a 250 g sale. Sell by weight, volume, length or area on the POS hardware you already own.

• Deduct the customer's own jar or tub before the weight is counted
• Sell by weight, volume, length or area, each with its own POS tile
• Stock stays in decimals, so a part-sold sack or roll is never rounded off
• Set up hundreds of products at once using rules based on your tags
• Runs on the POS device you already have, with no extra hardware
