FAQ
The register says "No stock location — cannot sell". Open Sales → Registers, edit the register and choose its Stock location.
A product shows out of stock at the till but we have it. The till only sells stock from its own location. Move or receive stock into that location in Products → Warehouses.
Can I delete a register? Not once it has taken money, because its shifts are financial records. Disable it instead.
Can two cashiers share a till? Yes, one after the other: the first closes their shift, the next opens a new one.
Returns at the counter? Use Return or refund on the register (see Ring up a sale).
