/ THE SHORT ANSWER
- 01Preserve original clauses next to normalised fields.
- 02Compare equivalent quantity, scope and commercial assumptions.
- 03Require explicit decisions on substitutions and exclusions.
/ dotSuper point of view
Quotation automation is valuable when it exposes non-equivalence before a purchasing decision.
Keep the supplier's qualifications visible
Compare equivalent quantities and scope before comparing price.
Route substitutions, omitted inspection and unclear tooling ownership to the responsible engineer or buyer.
Translation should make differences easier to inspect, not smooth them into an apparently standard offer.
DITP provides information and matching support for buyers engaging with Thai suppliers.
Such channels can help identify candidates, but the buyer still needs a transaction-specific comparison of what each supplier actually offers.
[1]
Thai and English quotations can describe the same product family while differing in pack quantity, inspection scope, tooling assumptions and delivery basis.
A table containing only translated product name and unit price hides the details most likely to change the decision.
Build a comparison record with three layers
The second extracts structured fields with a source location.
The third records the buyer's normalised interpretation and any assumptions needed to make the offers comparable.
Keep proposed substitutions distinct from confirmed compliance.
If a supplier offers an alternative material or process, label it as an engineering decision.
Do not let the assistant convert an approximate match into a statement that the requirement has been met.
Record what is missing.
An empty inspection field should mean unspecified until clarified, not inspection included.
The difference between no charge and no information is particularly important when comparing offers that use different document formats.
Use a maintained bilingual glossary for recurring technical and commercial terms.
Preserve product codes, units and quoted numbers directly from the source where possible.
A reviewer should be able to inspect the original wording without opening another disconnected application.
Use a comparison checklist before ranking prices
DotSuper's proposed application here is a reviewable extraction workflow, where the assistant prepares evidence and people decide unresolved technical and commercial differences.
[2]
Define a comparison basis before asking the model to rank suppliers.
State the quantity, required specification, included services and assumptions about future orders.
An attractive ranking is meaningless if each row describes a different scope.
Use the following checklist to decide which fields can be normalised and which need a supplier question.
Keep every adjustment traceable so finance can reproduce the comparison and engineering can challenge unsupported equivalence.
| Field | Question before comparison |
|---|---|
| Quantity and pack | Are the same number of units included? |
| Material and process | Does the offer match the requirement? |
| Tooling | Who pays, owns and maintains it? |
| Inspection | Which checks and records are included? |
| Delivery basis | Which costs and handovers are assumed? |
| Exclusions | Which unresolved items could change the price? |
Worked hypothetical: tooling changes the cheaper offer
Supplier A quotes THB90 per part plus THB20,000 tooling.
Supplier B quotes THB105 per part including tooling for the stated order.
Assume equivalent technical scope solely for this calculation.
Supplier A's first-order cost is THB110,000: 1,000 multiplied by THB90, plus THB20,000.
Supplier B's corresponding cost is THB105,000: 1,000 multiplied by THB105.
Supplier B is THB5,000 lower for this hypothetical first order.
The difference may reverse on repeat orders if tooling is reusable and no additional charges apply.
The buyer must clarify ownership, maintenance and expected order quantities before using a longer-term comparison.
Those assumptions are commercial questions, not facts the assistant can infer.
The team also finds that Supplier B's English summary omits an inspection qualification present in the Thai attachment.
It leaves that item unresolved and requests clarification before selecting either offer.
The arithmetic helps frame the decision but does not complete it.
Resolve differences and improve the next comparison
Their decisions should name the requirement, the proposed difference and the accepted outcome.
A general approval of the comparison table is too vague.
Treat quoted lead time as conditional on its stated trigger.
It may begin after drawing approval, tooling approval or another event in the offer.
Preserve that condition rather than normalising every phrase into a date from purchase-order issue.
Keep currency and tax assumptions explicit.
If offers use different currencies, finance should define the conversion basis and timing for the comparison.
The assistant can apply an approved method, but should not invent a current exchange rate or tax treatment.
Detailed comparison takes effort and can delay low-consequence purchases.
Use the full workflow where technical or commercial differences matter.
For standard catalogue items with established terms, a narrower comparison may be sufficient and easier to maintain.
Track which fields most often require follow-up and which extracted values reviewers correct.
Separate language errors from missing supplier information.
Better prompting cannot recover a term the quotation never states.
Turn repeated clarifications into a better request-for-quotation form.
Ask suppliers to state tooling, inspection and exclusions in defined fields while retaining their original offers.
Standardising the request can improve comparisons more than adding another model.
Evaluate the assistant using both straightforward and deliberately difficult quotation pairs.
Include offers with conflicting attachments, different units and incomplete scope.
Success means the system flags consequential uncertainty as well as extracting ordinary fields correctly.
The next useful exercise is one completed comparison with original clauses, normalised values and signed decisions on differences.
That record shows whether AI preparation makes the buyer's work clearer and where human technical judgement must remain explicit.
