Quick, no-signup calculators for the sums every ecommerce seller runs. Nothing is stored — enter your numbers and get the answer.
The exact stock level at which to reorder, so a delivery lands as you would otherwise run out.
The buffer that keeps you selling when demand spikes or a delivery runs late.
Your real net profit and margin on an eBay sale, with fees, postage and costs included.
These calculators answer one question each. Salync answers them continuously — tracking live stock and sales across eBay, Shopify, Amazon and UK marketplaces, and flagging reorders, low stock and margins automatically.
