Connect EPS SOS and Zoho Invoice. Payments and charges in your accounting, with Arbol.
How it works
A EPS SOS member writes to or calls your organization.
Arbol answers and asks for the EPS SOS order and authorization before offering a slot.
The appointment's payment or charge is recorded in Zoho Invoice.
Your team reconciles from Zoho Invoice, with every payment next to its appointment.
