Ensure accurate, auditable handling of POS invoice refunds posted to reservations or paymasters—preventing manual billing errors and enforcing a consistent financial trail.

***

### **Business Value**

* Preserves financial integrity between POS and guest billing.
* Enforces correct workflow and audit trail for all POS pay-to-room postings.

***

### **Use Cases**

* A guest settles a restaurant bill by charging it to their room, but later needs a refund.
* The cashier or accountant tries to reverse the revenue posting manually from the reservation or paymaster billing.
* The system now blocks manual cancellation or adjustments, guiding users to process refunds correctly from POS.

***

### **How to Use This Feature**

1. When a POS invoice is paid to a reservation or paymaster using “Pay to Room”, the system automatically posts the revenue on the guest’s billing.
2. If a refund is required for this invoice, **do not** attempt to cancel, split, or adjust the posting from the reservation or paymaster billing screens.
3. Instead, process the refund **directly from the POS system** for the original invoice.
4. If you attempt to cancel or adjust such a posting from billing, you’ll see a validation message:
   * *“Posting is linked to POS invoice \$invoice number, Please refund from POS.”*
5. This ensures all reversals are properly recorded in both POS and billing systems, maintaining a clear financial record.

***

### **Additional Notes & Validations**

* Manual cancellation, splitting, or adjustment of POS pay-to-room revenue postings is blocked from both Reservation and Paymaster Billing.
* Refunds must always be processed from the POS for these postings.
* This behavior helps avoid errors that previously led to stuck invoices or inconsistent financial data.
