A unit of measure conversion is a factor, and it applies in a specific direction. A case of twenty-four is not the same fact as twenty-four eaches per case, and inverting one by mistake produces a price that is out by a factor of five hundred and seventy-six rather than a factor of twenty-four.
The place this bites is the boundary between the ERP and the storefront. The ERP prices in a base unit, usually the one the warehouse counts in. The buyer wants to purchase in a sales unit. If the integration sends the base price and the storefront displays it against the sales unit, every price on the site is wrong, and it is wrong in a way that looks plausible enough to survive a demo.
Ask three questions before you publish. Which unit does the ERP hold the price against, which unit will the buyer see, and where does the conversion happen. If nobody can answer the third question, the conversion is not happening anywhere.
Why it decides a platform
Selling in a unit the ERP does not price in is a classic source of wrong prices on a B2B storefront. If the sales unit and the base unit differ and the connector does not convert, the number on the page is wrong by whatever the conversion factor is.
Also called: UOM, UOM conversion, unit of measure.
