I can't see all bills in the tablet
Updated
This can happen if a user with the role of waiter or storekeeper is logged on to the tablet. They will then only see their bills for the last 24 hours. A user with the newbie role does not have access to bills at all, and all senior roles (waiter/cashier, place manager, stock chief and merchant) will see receipts for the last 30 days. You will then find the entire bill history in your web administration.
