First make the offers answer the same request
Freeze the reference bottle, cap, water product, required good output, label, final pack and equipment boundary. Record each offer's revision and currency. If one proposal is machine-only and the other includes bottle making or packing, do not rank their printed totals as equivalent offers.
Ask each supplier to state the output proposed for every priority format and how it will be demonstrated. If a project requires a 1.5 L format but an offer quotes only a 500 ml catalog rating, the comparison has a technical gap before it has a price difference.
Worked scope comparison: two hypothetical offers
Illustrative example only: a buyer uses purchased PET bottles, has prepared water available, and requests filling, labeling, coding and finished-pack handling. The rows below are not actual supplier offers, prices or recommendations.
| Required item | Hypothetical offer A | Hypothetical offer B | Next action |
|---|---|---|---|
| Output for approved bottle | Catalog speed only | Bottle-specific proposal; test pending | Obtain the same output and test basis from both |
| Labeling and coding | Labeler included; coder absent | Both identified as included | Price A's coder and confirm integration |
| Conveyor connection | Open | Conveyor length stated; controls owner open | Confirm both mechanical and control boundaries |
| Second bottle format | Parts not listed | Parts listed; sample review pending | Confirm approved formats, parts and changeover method |
| Installation | Remote guidance | Site work offered as an option | Choose the required service basis, then price it equally |
Calculate an evaluated scope, not an invented final cost
For each offer, start with the quoted included equipment. Add only the options required by the agreed brief, then confirmed costs for omitted equipment, integration and agreed delivery/site obligations. Compare recurring costs separately and only where consumption, replacement intervals and operating assumptions are documented.
Unknown gap costs remain ‘not priced’. If offer A still lacks a priced coder or integration task, its evaluated total is incomplete; adding zero would create false precision. Avoid double-counting an option already included in a revised offer. Use a consistent currency/date basis if conversion is necessary and record the source rather than assuming exchange rates.
Use technical gates before a supplier score
A weighted score should not hide an unresolved requirement that could make the equipment unsuitable. Review bottle/cap compatibility, required output, scope completeness, test evidence and support responsibility first. Hold selection-critical gaps for written clarification instead of averaging them into a good overall score.
- Acceptable for comparison: required performance and scope are answered, with evidence and remaining conditions identified.
- Conditional: an alternative can be evaluated, but its effect, cost and approval remain explicit.
- Open: a selection-critical answer, responsibility or required price is missing; request clarification before approval.
Keep the chosen offer connected to acceptance
Record why one offer was selected, which alternatives were not chosen and which clarifications changed the decision. Carry the selected equipment, approved formats, documents and acceptance method into the technical agreement. Close or explicitly assign open items; a new quotation revision should not silently restore an earlier omission.
Allot Tech can support the organization of supplier responses. A checklist or scorecard does not certify a supplier, establish factory ownership or guarantee performance; the underlying project evidence still has to be reviewed.
Questions to close before purchase
How can I compare offers with different equipment lists?
Create one required equipment-and-service list, map both offers to it and mark every row's supply state. Ask for the missing items and selected options to be priced on that common basis before ranking totals.
Can a lower BPH machine be the better offer?
A larger catalog number alone does not establish a better fit. Compare the required good output on the approved bottle, the supporting equipment and the agreed test conditions. Do not choose an offer that leaves the actual production requirement unresolved.
Should an unknown cost be estimated as zero?
No. Keep it unpriced and identify who must clarify it. An incomplete evaluated total should be shown as incomplete, not presented as cheaper than a fully scoped offer.
What you should leave with
- A shared comparison basis
- A row-by-row difference register
- A cost comparison that keeps unknowns open
- A documented shortlist decision
