Free tools for multichannel sellers
Small things we needed and could not find an honest version of. Nothing to sign up for, no email, and every number checked against its source rather than copied off another calculator.
Square fee calculator
What Square keeps on a sale, and the exact volume at which Plus or Premium earns its subscription back. Square repriced in 2026 and most calculators still quote the old rates. Rates re-checked against Square's own pages automatically. Open the square fee calculator →
SKU generator
Every variant code at once, plus the one thing other generators leave out: which of your channels would trim it. Amazon cuts at 20 characters and does not tell you. Limits read from our own integrations, not from a help centre. Open the sku generator →
Each one is the short version of a problem QuickSync solves the long way
A SKU that fits every channel is the thing that lets one sale take a unit off the other seven shops. A fee you can predict is the thing that makes a second sales channel worth opening. The tools answer those questions once; the product answers them every day.
The tools are the easy half
Keeping one stock count behind up to eight shops is the other. QuickSync matches products by SKU across every channel you sell on, and tells you which ones it could not pair.
No credit card. After the trial, syncing stops if you walk away. Nothing is removed from your shops.
