An Invoice of 107,000 Baht Pays 104,000 Into the Bank — Thai Withholding Tax Is Computed on the Pre-VAT Base

Thai withholding tax is always computed on the amount before VAT. A service invoice of 100,000 baht plus 7% VAT totals 107,000, but the 3% withholding applies to the 100,000 base — 3,000 baht — so 104,000 is what actually arrives. Why computing it on the gross total skews every invoice in the same direction, why services are withheld on but pure goods sales generally are not, and why the withheld money is not lost, only slow.

How Long Should a Quotation Hold Its Price — Why 30 Days Is the Thai Standard, and Why the Expiry Date Is the Closing Tool Everyone Overlooks

The price-validity line is not a ritual at the bottom of a quotation — it is the ceiling on the cost and currency risk you carry on the customer's behalf, and the most legitimate reason to make a closing call. How to set the validity period to match the product, how to use the near-expiry window as the golden moment, and how to handle an already-expired quote without damaging the relationship.

A Quote Register with Win Rate — Why Most SMEs in Thailand Cannot Tell You What Percentage of Quotes They Win

A quotation produced in Word and sent as a PDF into LINE always disappears into the chat history — no register, no status, no count of why deals were lost. How to set up a quote register that makes follow-up systematic, and how to compute win rate the way the sales-management literature actually defines it: won ÷ (won + lost), decided quotes only.

Following Up on a Quote in Thailand Without Being Rude — Face-Saving Scripts and the Cadence That Works

Many Thai customers reject a price by going silent, because saying "too expensive" out loud feels like making the seller lose face — how to follow up in a way that opens the door to negotiation instead of forcing a yes/no, with a three-beat script: the first follow-up, the pre-expiry call, and the graceful close after a long silence — and why the cadence must be counted in working days, never on holidays.

The 13-Week Cash Flow Forecast — The Turnaround Profession's Standard Tool, and Why Thai SMEs Should Have One Before They Need It

Why it must be direct method, why thirteen weeks, why a negative balance does not mean death in the Thai SME context, and why a forecast never compared against actuals loses everyone's trust within a month.
