Two supplier quotes, one wrong suffix and a price per 100

Convert the per-board BOM into run quantities

Open the Northlight practice files. The three BOM lines are DEMO-R-A, DEMO-C-B and DEMO-J-C. They are fictional identifiers used to show the review process, not parts recommendations.

• L1 needs 2 pieces per board: 20 for a run of 10 boards.
• L2 needs 1 per board: 10 for the run.
• L3 needs 1 per board: 10 for the run.

The total requirement is 40 pieces. Keep the per-board and per-run quantities visible so a supplier reply cannot accidentally be compared with the wrong basis. Preserve the original replies; a rejected row still belongs in the review record.

Read the price basis before comparing totals

Beta quotes L1 at $12 per 100 pieces. The extended cost of 20 is 20 × 12 ÷ 100 = $2.40. Multiplying the quantity by 12 without the divisor produces $240.00, a hundredfold error.

Alpha offers 25 of the requested L1 at $0.08 each: $2.00. That is a different purchase quantity, so awarding it requires acknowledging the 5 excess pieces. The smaller line total does not remove the need to inspect identity, expiry and other charges.

Resolve the suffix conflict and extra row

Beta replies to L2 with DEMO-C-BX, while the BOM requests DEMO-C-B. The changed suffix is an identity conflict. Reject that line in this practice job rather than treating it as an interchangeable part.

Alpha also includes an unrequested DEMO-X line: 4 pieces at $2.00, or $8.00. Its full quoted file total is $22.00, including that extra. Exclude the extra from the award, while retaining its row decision so the file total remains explainable.

Account for all six quote rows

1. Award Alpha L1: 25 × $0.08 = $2.00.
2. Award Alpha L2: 10 × $1.20 = $12.00.
3. Exclude Alpha DEMO-X as unrequested.
4. Leave Beta L1 unselected; its $2.40 calculation remains in the review.
5. Reject Beta L2 because the part identifier conflicts.
6. Award Beta L3: 10 × $2.50 = $25.00.

Alpha awarded lines: $14.00 + fixed charge $5.00 = $19.00
Beta awarded lines:  $25.00 + fixed charge $4.00 = $29.00
Combined draft: $48.00
Needed: 40 pieces · Purchased: 45 · Excess: 5

The $48.00 result follows these particular decisions and entered charges. It is not a claim that this is the globally cheapest supplier combination, and it does not add unentered tax, duty or currency conversion.

Review the draft before it leaves your desk

Check quantities, part identities, price basis, quote validity and fixed charges against the original supplier replies. Confirm the excess explicitly. The generated handoff is for review; nothing has been purchased or sent.

A corrected supplier reply should be reviewed in a new job. Preserve the earlier files and decision record so someone can explain which quotation supported the draft.

What ThjalfiQuote adds to the review

A spreadsheet can reproduce the example. ThjalfiQuote keeps the mapped BOM, supplier lines, identity conflicts, quantity-basis checks, row decisions and draft handoff in one workflow. The app refuses unresolved material conflicts and requires relevant confirmations before an award.

The published limits are 500 BOM rows, 2,500 quote rows and 8 suppliers. Inputs are CSV or TSV, with one file per supplier and one currency per job. XLSX, PDF and CAD imports, split awards and pack conversions are outside this version.

There is no autosave, live stock check, FX conversion or supplier sending. Download the handoff and retain your source files. The verified environment is Chrome 152 on Linux; other operating systems and phone use have not been verified.

This article independently parsed the original free BOM and quotes using exact rational arithmetic and checked the saved expected draft. It did not rerun the paid app. The illustrated screens are from its published Chrome test.
