Operational finance, accounting-ready
Customer invoicing, supplier bills, payments and statement runs — designed to feed Xero cleanly.

What Finance & Invoicing is for
MDMS handles the operational finance side of a dealership and keeps it accounting-ready. Raise customer invoices and credit notes, run supplier bills and supplier payment runs, and produce statements and aged receivables reports so you always know who owes what and when it is due. The finance tools are designed to feed your external accounting platform cleanly, rather than trying to replace it.
Invoicing draws straight from the rest of the business: you can invoice from a sales order, a work order or a rental contract without re-entering any of the detail. Reconcile payments as they come in, then sync the results to Xero so your accountant always works from accurate, up-to-date numbers. Operations and accounting stay aligned without the usual double handling between systems. Staged work order invoicing and moving average parts costing are available as optional feature packs.
