Three different estimates are not necessarily three equivalent proposals. Check that contractors priced the same scope before comparing payable totals, timing and warranty.
Define the required result, quantities and units. State whether materials, delivery, preparation, waste removal and handover belong in the price. Identify mandatory requirements and alternatives separately. A labour-only proposal cannot be compared directly with one that also includes materials.
Check priced lines, additional work, the declared VAT treatment and confirmation of the final total. Exclusions should be explicit. Do not treat a missing price as zero or assume that all contractors are VAT registered. The responsible person should confirm the tax treatment applicable to the specific purchase.
A low price should not hide a missing mandatory line, unconfirmed scope or absent document. Bendria's comparison workflow uses structured proposal data and review status. A contractor's declaration is not the same as reviewed compliance. Changes to requirements or a proposal version need a fresh review.
A promise of two weeks needs context: from which date, are materials available, and does work depend on weather or resident access? Compare planned start, duration and bid validity. Payment terms, deposits and staged payments can also affect the practical choice.
A warranty duration alone does not explain coverage or exclusions. Review submitted documents, validity and responsibility for work and materials. Technical or qualification checks may require a competent professional. A platform comparison does not replace that assessment.
The organiser should explain the choice: complete scope, appropriate timing, acceptable terms or another pre-agreed criterion. Agree any price, duration and warranty weights before selection. A score supports a decision; it does not guarantee objective quality or future performance.
Assume both proposals target the same roof repair outcome. The lower headline price alone is not enough to select the first proposal.
| Criterion | Proposal A | Proposal B |
|---|---|---|
| Displayed final total | €8,500 | €9,000 |
| Waste removal | Excluded; price unknown | Included |
| Start and duration | Start unconfirmed; 10 days | Agreed start; 8 days |
| Warranty conditions | Clarification needed | Submitted for review |
Ask A to clarify the missing scope and conditions first. An unknown extra cost is not €0. Only after obtaining comparable, reviewed proposals should you decide whether the difference is justified by shorter timing and clearer terms. This example does not recommend a particular contractor.
The building organiser prepares a tender, common scope and requirements. Contractors submit structured proposals; a responsible reviewer checks the evidence, compares options and records the selection rationale. Public listings should not contain resident contacts or internal documents.
