Accounting Samut Prakan

Accounting for factories, warehouses, and import-export businesses

Accounting for factories, warehouses, and import-export businesses

Samut Prakan has one of the highest concentrations of factories and warehouses in Thailand, and it sits on the main goods gateway. Businesses we serve here share two characteristics: high-value inventory that turns quickly, and a large workforce made up of monthly salaried staff, daily workers, and subcontractors. These two areas are where accounting mistakes happen most easily, because the numbers move every day but are recorded monthly. We provide accounting for Samut Prakan businesses with a focus on keeping stock figures and payroll figures in the accounts aligned with reality each month — not discovering large variances at year-end.

What we handle

Monthly bookkeeping, transaction recording, and trial balance preparation
File withholding tax (ภ.ง.ด.1/3/53) and value-added tax (ภ.พ.30)
Close annual financial statements, file ภ.ง.ด.50/51, and submit to the Department of Business Development
Prepare payroll, payslips, and remit social security contributions
Take over from previous accountant, and perform a retroactive account review before accepting the engagement

Fast-moving inventory vs. records that fall behind

Warehouses that receive and dispatch goods every day often use a separate inventory system from the accounting system. When the two systems are not reconciled on a regular basis, discrepancies accumulate until the year-end count turns into a large unexplained sum. This is both an accounting problem and a difficult question when someone asks. What we set up is a monthly reconciliation point between the warehouse system and the books, so that variances are caught while they are still small and traceable.

Multiple types of employees in one factory

Most factories have regular staff, daily workers, and workers from subcontractors. These three groups have different compensation methods, tax withholding rules, and social security obligations. When they are all paid through the same payroll cycle, mistakes tend to recur every month without anyone noticing. We separate the calculation methods for the three groups clearly in the payroll system, and have a lawyer in the same office check that employment documents for each group match the actual payment method.

Besides the usual tax invoices, you must provide the full set of import customs documents and related import expenses, because the true cost of goods is made up of several components that arrive at different times. We will specify exactly what to keep from the first month.
