Employer procurement · Comparing commercial assumptions
Compare Manpower Quotations Against the Same Operating Brief
A lower quoted figure is useful only when you understand what it buys. Two proposals can use the same headcount and describe different duties, coverage, supervision or support arrangements. Build a comparison record around the employer's actual brief, then separate agreed terms from assumptions that still need answers. This guide explains that workflow without ranking suppliers or treating a proposal as confirmed availability.
Freeze the comparison baseline
Give every proposal reviewer the same dated requirement brief. Include locations, task boundaries, coverage windows, requested working positions, proposed duration and the questions awaiting review. Record which version each supplier used. If one response addresses an earlier version, resolve the difference before treating the offers as equivalent.
Distinguish requested working positions from the number of individuals needed for a roster. A position covered during two separate windows may require a different arrangement from one covered during a single window. Neither a city name nor a broad title explains that distinction. Attach the schedule and ask each proposal to identify its coverage assumptions.
Keep changes in a visible revision record. If operations adds another work area after proposals arrive, mark the added duties and ask how they affect scope and commercial terms. Do not quietly add the work to the comparison sheet while retaining the original price as if it covered the revised requirement.
Normalize units before comparing totals
Record the quoted unit exactly as supplied: for example, a stated period, agreed shift or another contractual unit. Identify what quantity and duration the proposed total represents. Do not convert a price to a different basis unless the conversion assumptions are explicit and accepted for the comparison.
Keep different commercial components separate. Identify whether supervision, materials, equipment, transport, accommodation or relief arrangements are included, excluded or unanswered. An unanswered item is not a zero-cost inclusion. Request clarification rather than estimating an unverified charge and presenting the estimate as a supplier's offer.
Record currency, the treatment of any stated taxes or charges, validity and payment assumptions from the proposal. Refer unanswered commercial or tax questions to the appropriate reviewer. This guide does not determine legal or tax treatment and does not supply a market price.
Use an assumptions matrix
| Field | What to compare | How to record a gap |
|---|---|---|
| Duty scope | Included tasks, excluded tasks and work areas | Mark the missing boundary and request a revised scope |
| Coverage | Positions, windows, period and relief assumptions | Keep unconfirmed roster assumptions open |
| Quoted unit | Unit, quantity, duration and stated total | Request the basis before calculating equivalence |
| Site support | Supervision, materials, equipment and access responsibilities | Name the party expected to accept each responsibility |
| Transport and accommodation | Included arrangements and employer responsibilities | Ask for an explicit inclusion or exclusion |
| Change and replacement | Request, review, acceptance and commercial adjustment process | Do not infer an immediate replacement commitment |
Use consistent status labels such as stated, clarified and unresolved. Keep the source quotation and clarification reference beside each entry. A spreadsheet cell is a summary of evidence; it should not replace the underlying statement or become a new promise.
Work through a fictional comparison
For illustration, an employer requests three warehouse-support working positions at one site during a specified coverage window. Picking and packing are included; equipment operation is excluded. Proposal A states the coverage but leaves transport responsibility unanswered. Proposal B identifies transport responsibility but omits the relief assumption. No price or supplier identity is asserted in this example.
The reviewer should not declare either proposal fully comparable yet. Ask A to resolve transport and B to explain coverage during absence or schedule changes. Check that both responses refer to the same brief and retain the equipment-operation exclusion. Record any effect on the quoted unit and terms rather than assuming the clarifications are free additions.
Suppose operations then requests another coverage window. That is a revision to the requirement, not a clarification of the original three positions. Update the baseline, identify the changed window and request the necessary commercial review. Three working positions still do not establish the final number of individuals or an accepted start date.
Separate evidence review from commercial comparison
A clear price basis does not establish a supplier's authority or an individual's suitability. Keep the contracting entity, relevant permissions, role evidence and site prerequisites in a separate review record with the responsible reviewer. Use the supplier review checklist for that evidence workflow.
Likewise, documentary review does not resolve an unclear duty boundary or support responsibility. Procurement and operations should reconcile the two records: identify what is accepted, what is still conditional and who will resolve each condition. Avoid turning an unresolved question into a favourable score simply because the proposal is concise.
Close the review with an acceptance record
Before recommending an award, identify the final brief version, proposal version, clarifications and remaining conditions. Record the intended contracting parties and the people responsible for commercial and operating decisions. Distinguish an internal recommendation from a binding acceptance or confirmed assignment.
Use a short closeout checklist: scope matched; units understood; support responsibilities explicit; coverage assumptions reviewed; evidence review assigned; open conditions recorded; changes controlled. Retain excluded duties where they matter to site planning. A preferred proposal should not erase those boundaries.
Prepare a new brief with the requirement-brief guide, review outsourcing responsibilities, or send the actual requirement through the quotation route. Share business planning inputs rather than unnecessary personal documents. The worked example is illustrative and establishes no supplier rating, staffing inventory, price or deployment guarantee.
