More detail
Plenty of trades sell by the unit, and for them this is a non-issue. The trades that price by weight, where a scale sets the amount, have a particular requirement that not every POS supports the same way.
Rather than assume, ask the Veira team how price-by-weight or scale entry works for your trade. If it is not yet supported, it is better to know that up front than to discover it at the counter.
