Combined payments, accounting and refunds

Invoice ownership and allocation

Invoices remain attached to the resident payer's billing account. One combined provider charge does not create a new billing account and does not move an invoice to a different user.

Journal entries and audit

Settlement is atomic. Either every component records its canonical mutation, balanced source-linked journal entry, and exactly-once audit, or none of those writes commit. Invoice, amenity, and event histories remain independently legible.

The provider processing fee posts once for the aggregate charge. It is not duplicated in each component JE.

Refunds

Refund the invoice, amenity, or event component through its normal domain workflow. Kore targets the exact component allocation, enforces its remaining principal cap, and preserves the other components.

Combined-payment refunds return component principal only. They do not return the resident card surcharge or reverse the provider's processing cost merely because one component is refunded.

Never create a compensating manual entry or charge the resident again while a captured bundle is processing. Escalate unresolved or unattributed provider refunds through the reconciliation playbook.
