In business operations, managing invoices and products are two key factors that determine operational efficiency and legal compliance. To understand the importance of automation solutions, we need to analyze the needs of each customer group in detail.

Analyzing Customer Needs by Group

1. Household Business

According to Government Decree 01/2021, household businesses have the following characteristics:

  • Unlimited liability : The head of the household is liable with all personal assets for business activities.
  • Lack of legal personality : Operating under the name of an individual, not as an independent legal entity.
  • Quantity limit : Each individual/household is only allowed to register one business.
  • Integrated financial management : All income from personal and business accounts is counted as household income.

Financial management challenges

Household businesses often face the following difficulties:

  1. Difficulty separating personal and business income : All accounts are considered sources of household income.
  2. Double tax calculation method : Applying both the declaration method and the lump-sum method as prescribed.
  3. Separation of accounts required : Decision 3389 recommends opening separate accounts for business operations.
  4. Managing input invoices : It is necessary to keep complete records of expense invoices for accurate tax declaration.

Specific needs

  • A simple, user-friendly product management solution for homeowners without in-depth accounting knowledge.
  • Automatically collect and categorize input invoices (expenses) from various sources.
  • Simple financial reports help capture monthly revenue and expenses.
  • Issue invoices quickly for retail customers.

2. Small and Medium-sized Enterprises (SMEs)

Operating characteristics

  • Having legal personality : Limited liability within the scope of registered capital.
  • Staff size : 5-50 employees, requiring clear delegation of authority.
  • Multiple sales channels : Online, offline, dealers, distributors
  • Accounting system : There is a dedicated accounting department.

Management challenges

  1. Large volume of invoices : Hundreds of input/output invoices per month
  2. Managing diverse products : Multiple SKUs, multiple suppliers, multiple units of measurement.
  3. Complex tax reporting : Input/output VAT, corporate income tax settlement.
  4. System integration : Requires connection with accounting software (MISA, MISA AMIS, etc.)
  5. Traceability : Managing shipments, expiration dates, and origin of goods.

3. Large Businesses & Corporations

Operating characteristics

  • Large scale : Over 100 employees, multiple branches and subsidiaries.
  • Multi-industry : Operating in various business sectors.
  • ERP system : Already has a comprehensive management system (SAP, Oracle, etc.)
  • Complex process : Multi-level delegation of authority, strict approval process.

Introducing GTG CRM Solution

After a detailed analysis of the needs of each customer group, GTG CRM provides a comprehensive solution with two core features :

Automatic Electronic Invoice Generation
