Your Business Complying with Electronic Invoices Yet?
According to Decree 123/2020/ND-CP, all businesses and business households (HKD) with revenue over 100 million VND/year are required to use electronic invoices. If you are in a situation where:
- Using MISA only for issuing invoices: Invoice software in one place, inventory management in another, CRM customer data in Excel
- Managing inventory with Excel: One wrong row, millions lost, constant discrepancies at month-end inventory counts
- 3 software for 3 tasks: MISA for invoices, Excel for inventory, notebook for customers, time-consuming, prone to errors
- Multiple warehouses, multiple branches: Don't know which warehouse is in stock, which needs replenishment
- Accumulating software costs: MISA 1-3 million VND/year + inventory management tools + separate CRM
Over 5.5 million business households in Vietnam are transitioning to electronic invoices. Many businesses are still using fragmented solutions, with invoices in one place, inventory in another, and customers elsewhere.

Using electronic invoices according to Decree 123/2020/ND-CP not only helps businesses comply with legal regulations but is also a crucial step towards standardizing business processes. However, if data remains scattered across multiple software and Excel spreadsheets, businesses will continue to lose time and be prone to operational errors.
GTG CRM helps solve this problem by integrating electronic invoices, inventory management, order management, and customer CRM into a single system. When all data is connected, businesses can track their operations more clearly, reduce manual tasks, and operate more efficiently.
If you're looking for an electronic invoicing compliance solution that also manages your entire sales operation, GTG CRM is a simple choice to start with.
