Has your business complied with electronic invoicing regulations?

Has your business complied with electronic invoicing regulations?

According to Decree 123/2020/ND-CP , all businesses and household businesses with annual revenue exceeding 100 million VND are required to use electronic invoices . If you are in the following situation:

• Using MISA just for issuing invoices : The invoicing software is one thing, the inventory management is another, and the customer CRM is in Excel.
• Inventory management using Excel : One incorrect entry can cost millions, and discrepancies are constantly appearing during end-of-month inventory checks.
• Three software programs for three tasks : MISA for invoices, Excel for inventory, and a customer ledger; time-consuming and prone to errors.
• Multiple warehouses, multiple branches : It's difficult to know which warehouses have stock and which need more.
• Software costs pile up : MISA 1-3 million VND/year + inventory management tools + separate CRM

Over 5.5 million business households in Vietnam are required to switch to electronic invoices. Many businesses still use fragmented solutions, with invoices in one place, inventory in another, and customers in yet another.

Conclude

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

GTG CRM solves this problem by integrating electronic invoicing, inventory management, order management, and customer CRM into a single system. With all data connected, businesses can track operations more clearly, reduce manual processes, and operate more efficiently.

If you're looking for a solution that complies with electronic invoicing requirements while still managing all your sales operations, GTG CRM is a simple choice to get started.
