Has Your Business Complied with Electronic Invoices Yet?

Is Your Business Compliant with E-invoicing?

According to Decree 123/2020/ND-CP, all businesses and business households (HKD) with revenue exceeding 100 million VND/year are required to use e-invoices. If you are currently in a situation where:

• Using MISA only for issuing invoices: Invoice software in one place, warehouse management in another, customer CRM in Excel
• Managing inventory with Excel: One wrong line can cost millions, monthly inventory checks consistently show discrepancies
• 3 software for 3 tasks: MISA for invoices, Excel for inventory, notebook for customers, wasting time, prone to errors
• Multiple warehouses, multiple branches: Don't know which warehouse is stocked, which needs replenishment
• Overlapping software costs: MISA 1-3 million VND/year + warehouse management tools + separate CRM

Over 5.5 million business households in Vietnam are transitioning to e-invoices. Many businesses are still using fragmented solutions, with invoices in one place, inventory in another, and customers elsewhere.

Double-Entry Accounting According to VAS - Bookkeeping within the Platform

Conclusion

The use of e-invoices according to Decree 123/2020/ND-CP not only helps businesses comply with legal regulations but is also a crucial step in standardizing business processes. However, if data remains scattered across multiple software and Excel spreadsheets, businesses will continue to waste time and be prone to operational errors.

GTG CRM addresses this issue by integrating e-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 are looking for an e-invoicing compliance solution that also manages your entire sales operation, GTG CRM is a simple choice to get started.
