Feature Introduction

Electronic invoicing is a key feature of GTG CRM that helps businesses manage all incoming and outgoing invoices centrally, automatically, and efficiently.

Electronic Invoice Interface

Why is Electronic Invoice Management Necessary?

In business, there are two most important concepts:

Concept	Describe	Invoice type
Revenue	The amount of money collected from sales	Output invoice (issued to the customer)
Expense	The amount of money used to buy goods for resale.	Input invoice (issued to you by the supplier)

GTG CRM makes generating and managing invoices incredibly easy!
