Problem:
When restaurant staff split a table bill across covers, our POS sends the full order state to Mews as signed line items — the original sale as positives, then negatives for every item reallocated to the other covers. The connector passes these through unaltered to preserve line-by-line reconciliation with the POS fiscal log.

The result is that one guest's folio receives the entire table's order and then credits removing everyone else's food. A recent two-item POS receipt arrived in Mews as 19 bill lines: charges, then credits, netting to the correct amount. Wine, mains and sides belonging to other diners all appeared at full price on one guest's bill before being taken back off.

Nothing is wrong financially — every check reconciles to the penny and no guest has been mischarged. It is purely how the folio reads, and guests query it.

This is worse for long-stay properties. Our guests receive a consolidated monthly invoice, so these lines accumulate across a whole month on the same document rather than disappearing at checkout. Around one in five room-charged restaurant checks is affected. Any Mews property running a POS integration where staff split table bills will see this, and it bites hardest for long-stay, serviced-apartment and senior-living operators.

Solution:
Add an option to collapse exactly-offsetting bill lines on the printed bill or invoice — where the same product is posted at a value and reversed at the same value within one order — while leaving both entries fully intact in the ledger, the accounting export and all reporting.

A rendering change only. Nothing netted, suppressed or removed from the accounting data, so the audit trail between POS and PMS is unaffected.
