Accounting in Ang Thong

Accounting for mid-sized contract manufacturing and food processing businesses.

Accounting for mid-sized contract manufacturing and food processing businesses.

Ang Thong is home to many mid-sized contract manufacturing and food processing businesses across several districts. Many produce goods for other brands under their own names. This business model has specific accounting considerations: raw materials may be supplied by the client and are not owned by your business, and the manufacturing fee is often linked to actual production volume, not the input received. Without clear separation from the outset, your inventory will include items that don't belong to you. We handle accounting for Ang Thong businesses by first making the ownership of raw materials clear.

Client-Supplied Raw Materials in Your Factory

When a client supplies raw materials or packaging for manufacturing, those items are in your possession but are not owned by your business. In accounting, they are not inventory. However, you need a verifiable system to track how much was received, used, and remains, because it's both a contractual responsibility and something auditors will look at during inventory checks. That's why we set up two separate ledgers from the beginning.

Manufacturing Fees Based on Actual Output

Contract manufacturing agreements typically base fees on the quantity of goods produced that pass quality standards, not on the raw materials received. So the question of who bears the cost of damaged or defective output is primarily a contractual matter. If the contract is vague, it leads to disputes with the client and unaccountable cost figures. That's why we have a lawyer in the same firm review the contract first, then we structure the accounting entries accordingly.
