Calculate your salary legally while still having control over the numbers — Why is this important?

Are you facing this problem?

Mr. Dung runs a service company with 18 employees in Ho Chi Minh City. Every month-end, his accountant spends nearly two days on an Excel file: keying in salaries, calculating social insurance, cross-referencing progressive personal income tax brackets, and then copying numbers to the accounting software. A single tax bracket error throws off the entire sheet, and he only discovers it when an employee raises a concern.

He had tried a payroll software before, but he encountered the opposite problem: he couldn't see what rates and thresholds the software was using, and he couldn't make any adjustments. When the regional minimum wage changed mid-year, or when his company's situation differed from the "default," he had to email the provider and wait. He was caught between two extremes: manual calculation was prone to errors, while using software meant losing control.

What you truly want to achieve

Mr. Dung wants a middle ground: a system that calculates payroll automatically and accurately, yet is transparent and adjustable — so he (and his accountant) can see precisely which legal figures are being applied, know their legal basis, and make adjustments when needed without waiting for anyone. He wants payroll finalization to automatically post to the accounting ledger, with the correct accounts and period — eliminating a second round of manual entry. And if his company opens a branch in another country in the future, he wants to use the same system instead of buying new software.

In other words: automation to reduce errors, while retaining control over the numbers.

How GTG CRM helps you achieve this

GTG CRM places the HR & Payroll module right next to sales and accounting, designed with the principle of "you are in control of the numbers":

Pre-built national data set. Select Vietnam (other countries are being prepared), and the system is already equipped with social insurance/health insurance/unemployment insurance contributions, employer contributions to the trade union fund, progressive personal income tax brackets, regional minimum wage levels, and year-to-date accumulation calculations. The default figures are provided by GTG, based on the Social Insurance Law 2024, Employment Law 2025, Personal Income Tax Law 2025, Trade Union Law, along with Decree 105/2026/ND-CP and Decree 293/2025/ND-CP — Mr. Dung (or his accountant) can review and adjust them according to the company's reality.

You can view and adjust all numbers yourself. In the Payroll Settings, you can open any item (rates, thresholds, brackets, caps) and adjust it to your company's actual situation; the next payroll period will use these changes. Not satisfied? Reset to default with a single click to revert to the GTG-provided figures.

All changes are tracked. Who changed which rate, from what old value to what new value — all of it is recorded. This is data that affects actual salaries, so an audit trail is essential.

Payroll finalization automatically posts to the ledger. When you finalize a payroll period, the salary expense journal entry is posted directly to the general ledger (Debit Salary Expense / Credit Employee Payables + Accruals), just like invoices are accounted for — ending the need for a second manual entry.

The key point regarding responsibility: GTG does not "guarantee" legal figures for you and leave you to bear the consequences if they are wrong. GTG provides a transparent and adjustable default — while you (or your accountant) are the ones who review, adjust, and take ownership of the final numbers. This is exactly how a professional payroll system should operate: the tool handles the calculations and bookkeeping, while the business owner retains decision-making authority.

Results you will get

Reduced errors and time savings: automatic payroll, social insurance, and personal income tax calculations, finalized in minutes instead of two days of Excel work.

Peace of mind with control: clearly see every legal figure, know its source, and adjust it yourself when laws change — no more waiting for the provider.

Audit trail: every rate change is recorded, transparent for accounting and settlement.

No double entry: payroll costs are automatically posted to the correct ledger account and period.

Scalable: with the same system, currently paying salaries to Vietnam standards; other countries are being prepared.
