Define the purchasing question
A comparable request for quotation gives every supplier the same specification, quantity and charge boundaries.
Send the same approved scope to suppliers, record exceptions, then compare offers within equivalent groups. The downloaded files are empty and illustrative worksheets, not certifications.
Collect measurements that match the calculation
Assign a revision-controlled SKU and describe required material, dimensions, tolerances, print, usable quantity, quality evidence, delivery schedule and receiving location. Leave unknown values explicitly unconfirmed.
Use complete BOM costs for two qualified systems and add assembly and order charges once. This compares whole systems, while supplier comparison pages compare offers within one packaging specification.
- A complete BOM cost per good product (currency)
- B complete BOM cost per good product (currency)
- A assembly per product (currency)
- B assembly per product (currency)
- A order freight and setup (currency)
- B order freight and setup (currency)
- Equivalent good products (units)
Work through an illustrative case
Total = Good products × (Complete BOM cost + Assembly) + Order freight/setup
A totals EUR 6,300 and B totals EUR 6,200 for 10,000 good products.
Replace these illustrative inputs with measured data or a quotation for the same scope. Change one assumption at a time so that a difference can be traced to a dimension, quantity, charge or process change.
Avoid the expensive comparison error
A supplier can quote a low unit price while excluding tooling, minimum order or delivery. Do not turn a missing charge into zero when importing the offer into a comparison.
- Use measured quantities and charges valid for this exact specification and period.
- Cost calculations do not qualify performance, protection or a supplier.
Case: turn the specification into a filled request
Define SKU BOX-01, artwork revision A, an internal 400 × 300 × 200 mm requirement and 10,000 accepted boxes. Record board and performance requirements from approved evidence rather than inventing a grade from geometry.
The RFQ builder includes known measurements and marks missing fields for supplier confirmation. Ask for original price unit, MOQ and tier thresholds, delivery boundary, one-time tooling ownership, repeat charges and quote validity. Review the generated file before sending it.
Common questions
What should I verify before using this result?
Assign a revision-controlled SKU and describe required material, dimensions, tolerances, print, usable quantity, quality evidence, delivery schedule and receiving location. Leave unknown values explicitly unconfirmed.
Does this calculation approve the packaging?
No. It estimates only the stated quantity, conversion or cost boundary. Technical performance and any required test or supplier approval remain separate.
