Accounting in Samut Sakhon

Accounting for food processing factories and labor-intensive businesses

Samut Sakhon is the nation's center for fisheries and seafood processing. Most of the businesses we handle here are processing plants, cold storage facilities, exporters, and wholesale raw-material suppliers. They share two features that make accounting harder than for typical businesses. First, raw materials are fresh and naturally lose weight during processing, so incoming weights never match outgoing output. Second, these operations rely on large workforces that include permanent staff, daily hires, and foreign workers who must have complete legal documentation. We handle accounting for Samut Sakhon businesses by making these two areas a primary focus, not an afterthought.

Production waste that must be provable

Food processing plants naturally have production losses — from trimming, moisture loss, and rejected items. These are costs for accounting purposes, but they must be provable as real and reasonable percentages of the production process. Businesses without daily production records can’t prove them when questioned, and often face adjustments. We design a system to record input/output weights at each stage that ties directly into the cost figures on the books.

Foreign workers: employment documents must match the accounts

Businesses with many foreign workers maintain two sets of documents that must align: employment documents required by labor and immigration law, and the payroll and contribution records in the accounts. When these don’t match, the problem often doesn’t start with tax — it starts with a labor inspection, and then spreads to the numbers on the books. Having a lawyer in the same office as the accounting team allows both sets to be reviewed together every month.
