Commission (GP) rates on Thai e-commerce platforms have gone up 2-3 times so far in 2026, and one large brand says its online selling costs have risen about 5-6% since the start of the year. Platforms have not said where the increases will stop. Check your online P&L including packing and shipping, since the real cost can match offline retail. Consider spreading sales to lower-commission Thai platforms and your own website, and keep in mind that raising prices may be the last resort.
