# `PUT /article/{sku}/prices`

Protected. Requires a valid session cookie (`credentials: 'include'`).

Replace POS prices by SKU (net > gross; price=net, tax=taxRate %)

Replace-all prices for the company POS customer group.
`net` takes precedence over `price` (legacy alias for net) and `gross`.
`tax` and `taxRate` both specify the tax rate percentage (e.g. 19 for 19%), not monetary tax.
When `gross` is provided, net price is computed as `gross / (1 + taxRate / 100)`.
Prices are strictly scoped to the company's designated POS customer group (customergroupId returned on GET).
Empty `prices` clears all POS prices. Returns the same shape as GET by SKU.
