Zynk connects HaloPSA to your accounting and ERP systems, keeping service, procurement, and finance data in sync without manual re-entry. Service requests, contracts, purchase orders, billable time, and invoices flow automatically between HaloPSA and the systems you already run on, with two-way sync across Customers, Invoices, Invoice Payments, Purchase Orders, Sales Orders, and Suppliers. The result is less admin, fewer invoicing errors, and real-time financial oversight of your contracts and service agreements.
