Unknown store
What you see
On the POS, on the Till tile (or in the admin, on the Till close page), a message appears with this title when you open, close or reopen the till. The title is “Unknown store”. Code: ZP-TILL-LOCATION-UNKNOWN.
What happened
This location is not one of the shop’s stores in zrsPOS.
What to do
The store must exist in Settings › Stores with its own série. Add or fix it there, then try again. A Shopify location that is not used for sales (a warehouse, for example) does not have a till.
Can zrsPOS do it for you?
No. This one needs a person.
Still stuck?
Write to support@zrspos.com and quote the code ZP-TILL-LOCATION-UNKNOWN, with the store, the till (if the store has several) and what you were doing. For the way the Till works, see the till close manual.
