Supplier Price Comparison Sheet
The comparison sheet is the record of why a supplier won: quotations side by side, judged on more than the price line, with the reason written down. The free Excel file below carries a three-supplier form and a multi-item sheet, and the unit price calculator further down does the per-unit arithmetic live. No signup and no email required.
Scope: this is a private organization’s internal record. Government bodies follow the public procurement rules and the e-GP system, which this form does not replace.
Looking for a quotation (ใบเสนอราคา) form? The supplier issues the quotation; the comparison sheet lines up the quotations you receive.
Bilingual Thai and English, A4. Two working sheets: a comparison form (one purchase, up to three suppliers as columns, criteria from quotation reference to warranty as rows, then the selection, its reason and three signatures) and a multi-item sheet with per-supplier totals that calculate automatically. Free to use and adapt.

Unit price calculator
The arithmetic of the sheet, done live: enter up to three offers with their pack sizes and the calculator puts them on one per-unit number, VAT included. Nothing you type leaves this page.
Enter a price and pack size on at least two offers to compare.
VAT is calculated at the standard 7%. Delivery fees are spread across the pack.

Where the comparison sits in the purchasing flow
The requisition asks for the item, purchasing requests quotations, and the comparison sheet lines up the quotations before a purchase order goes to one supplier. It is the record auditors ask for when they ask “why this supplier?”.
The completed sheet, with the quotations filed behind it, is the evidence. The selection line names the winner, the reason line says why in one or two sentences, and the signatures show who compared, who checked and who approved.
What to compare beyond the price line
The criteria rows on the form, and what each one catches:
| Criterion | What it catches |
|---|---|
| Specification compliance | An offer that misses the requested specification can mean buying again later. Judge against the requisition, not the brochure. |
| VAT treatment | One price quoted including VAT against two quoted excluding it skews the comparison by 7%. Align them before comparing totals. |
| Delivery time | A price that arrives six weeks late can cost more than the difference. Compare the promised dates as well as the numbers. |
| Credit and payment terms | 30-day credit against payment-before-delivery is a real financial difference the price column does not show. |
| Warranty and after-sales | For instruments: warranty length, parts availability and who answers when it breaks. The row exists so the answer is on record. |
| Price validity | A quotation that expires before approval finishes is a comparison that has to be run again. Record the valid-until dates. |

Common questions
Do we always have to choose the lowest price?
No. The lowest offer wins by default only when everything else is equal; a supplier can legitimately win on specification fit, delivery, credit terms, warranty or parts support. What purchasing must do is write the reason on the selection line, so the decision can be defended later without reconstructing it from memory.
How many quotations do we need?
Whatever your organization’s purchasing policy says. Two or three is the common requirement, often waived below a value threshold. The form carries three supplier columns because three is the widespread convention; leave a column blank when policy requires fewer.
Is this the form government agencies use?
No. Government procurement in Thailand is governed by the public procurement act and runs through the e-GP system, with its own documents and thresholds. This sheet is the internal record a private organization keeps. If you are selling to or buying for a government body, see our guide to e-GP supplier registration.
Is the download really free? Do I need to register?
Yes, it is free, and no. There is no signup and no email form. Download the file, put your organization’s name on it, and adapt the criteria rows to your purchasing policy.
