Many businesses using the Profilo S900 ECR ECR POS assume they are blocked by a “credit card single-transaction limit” when a high-value payment fails. In practice, this is often not a real bank POS limit. The issue usually appears because, above a certain threshold, the device requires the sale to be completed through the invoice/e-document workflow rather than the standard receipt flow.
Important: To access the Invoice menu, the Sale screen must be empty. Do not enter any amount first. If an amount has already been typed, cancel or clear it and return to a blank sale screen.
Step by step:
1) Open the Sale screen (make sure the amount field is blank).
2) Enter the Invoice menu.
3) Select Invoiced Sale.
4) Choose the correct option:
- If the customer is an e-Invoice taxpayer → select e-Invoice.
- If not → select Invoiced Sale (often works as an e-Archive flow, depending on device wording).
5) When asked “Will the invoice be issued later?” choose Yes.
6) Enter the requested customer details (company tax number or personal ID, according to the device flow).
7) When asked “Enter amount now?” choose Yes.
8) You will return to the Sale screen. Now enter the amount.
9) Complete the payment by selecting Cash or Credit Card.
This is why users often search for phrases like “Profilo S900 ECR single transaction limit” or “cash register POS credit card limit” when a high-value payment fails. In many cases, the practical solution is simply switching to the correct invoiced sale workflow and completing the transaction through the Invoice menu.
