RFQ practice
How to build a decision-ready industrial RFQ: a practical guide to comparable bids and better project decisions
Most bid comparisons fail before the bids arrive, because each supplier answered a slightly different question. This framework shows what to put in the request so the answers can be compared — and how to normalize them when they still differ.
Short answer
A decision-ready RFQ states measurable requirements, acceptance criteria, capacity and operating duty, interfaces and utilities, compliance expectations, installation and commissioning duties, service and warranty terms, and a common commercial schedule. It also tells suppliers how bids will be evaluated. When bids arrive, normalize them to one scope and lifecycle basis before comparing prices.
What is a decision-ready RFQ?
A request for quotation (RFQ) is decision-ready when every qualified supplier can price the same scope without guessing, and the buyer can compare the answers line by line. It is less about length than about removing ambiguity.
The test is simple: if two suppliers read the RFQ and make different assumptions about capacity, utilities, scope or acceptance, the RFQ is not finished.
Key point: Ambiguity in the RFQ becomes price differences that are not real.
How do you write requirements suppliers can price?
Separate what is mandatory from what is preferred, and describe performance rather than a particular design wherever possible. Performance requirements let suppliers propose their best solution while keeping the result measurable.
| Requirement type | What it states | Example of the form |
|---|---|---|
| Performance | The result the equipment must achieve | Throughput, product quality, temperature, losses |
| Operating conditions | Where and how it will run | Ambient range, hours per day, product variability |
| Mandatory constraints | Non-negotiable limits | Footprint, available power, hygiene zoning |
| Preferences | Desirable but tradeable features | Brand of components, level of automation |
| Information required | What the bid must contain | Drawings, utility consumption, spare-parts list |
How should capacity and operating duty be specified?
Capacity is meaningless without its conditions. State it with the product, the operating pattern and the basis of measurement.
- Nominal and peak throughput, with the unit and the product it refers to
- Product properties and their range: size, moisture, temperature, density or similar
- Operating hours, shifts, days per year and expected changeovers
- Expected availability or planned downtime, if you have a target
- Growth allowance, if the design should accommodate later expansion
How do you define interfaces, utilities and battery limits?
Interfaces are where scope gaps hide. Define each connection point and who delivers up to it.
| Interface | What to specify |
|---|---|
| Electrical | Voltage, frequency, available capacity, connection point, who supplies cabling |
| Water and drainage | Pressure, flow, quality, discharge limits, connection points |
| Compressed air, steam, gas | Pressure, quality, capacity, who supplies distribution |
| Controls and data | Communication protocol, integration with existing systems, who programs what |
| Mechanical | Upstream and downstream equipment, transfer heights and speeds |
| Civil and building | Foundations, floor loads, openings, who builds them |
What acceptance criteria belong in the RFQ?
Acceptance criteria turn requirements into tests. Include them in the RFQ so suppliers price the tests and design for them. Typical stages are a factory acceptance test (FAT) before shipment and a site acceptance test (SAT) after installation.
- State each measurable criterion and its tolerance
- Define the test method, duration and the product to be used
- State who provides product, utilities and personnel for each test
- Define what happens if a test fails: correction, retest and responsibilities
- Link payment milestones to passed tests where appropriate
How should compliance be reviewed?
Compliance depends on the country, sector and product. Ask suppliers to state which standards and regulations their equipment is designed to, and to provide the related documentation. For example, machinery placed on the EU market falls under the EU Machinery Regulation (EU) 2023/1230; other markets have their own rules.
The buyer remains responsible for confirming which requirements apply to the project. Food-safety, animal-health, electrical, pressure-equipment, environmental and building rules usually need review by qualified local professionals before the RFQ is finalised.
What should you request for installation, commissioning, service and warranty?
- Installation: what the supplier supervises or performs, and what the buyer provides
- Commissioning: start-up support, duration and the condition for handover
- Training: who is trained, for how long and in which language
- Documentation: manuals, drawings, certificates and their language
- Spare parts: recommended start-up and two-year lists, priced separately
- Service: response times, remote support, local presence and rates
- Warranty: duration, start date, what is covered and excluded
- Delivery terms: the Incoterms® rule and named place, so freight and risk transfer are clear
How do you normalize bids for a fair comparison?
Hypothetical example — not market data
Normalization adjusts every bid to the same scope and basis before prices are compared. Do it the same way for every supplier and keep the adjustments visible.
| Hypothetical bid | Quoted price | Missing scope (estimated) | Normalized price |
|---|---|---|---|
| Supplier A | USD 820,000 | Installation USD 60,000 + spares USD 25,000 | USD 905,000 |
| Supplier B | USD 870,000 | Spares USD 25,000 | USD 895,000 |
| Supplier C | USD 940,000 | None | USD 940,000 |
Normalized bid = quoted price + estimated cost of exclusions (+ lifecycle items, if compared)
- List every inclusion and exclusion per bid against the RFQ scope
- Estimate the cost of each exclusion using one consistent assumption
- Align delivery terms, currency and payment schedule
- Add lifecycle items you can estimate: energy, consumables, spares, service
- Score technical fit and risk separately from price
In this illustration the lowest quoted bid is not the lowest normalized bid. The normalized figure is still not the decision: technical fit, delivery time, references you can verify and risk must be scored alongside it.
Key point: Compare normalized bids, then weigh price against technical fit and risk.
When should you consult technical, financial and regulatory experts?
- Technical: when the process is new to your organisation, when performance guarantees matter, or when interfaces span several suppliers
- Financial: when the project needs external financing, when currency or payment terms carry risk, or when lifecycle cost drives the decision
- Regulatory and legal: for permits, product and food-safety rules, animal health, environmental limits, import requirements and contract terms
- Independent inspection: for factory acceptance tests or quality checks you cannot attend yourself
Which questions should the RFQ ask every supplier?
Ask the same questions of every bidder, in the same order, so the answers can be placed side by side.
- Which requirements do you meet in full, in part, or not at all?
- What assumptions did you make where our RFQ was silent?
- Which performance values will you guarantee, and how will you test them?
- What is excluded from your price, and which Incoterms® rule and named place apply?
- What utilities, foundations and site works must we provide?
- What is your dated delivery slot, and which components drive lead time?
- Where are service staff and spare parts, and what response time do you commit to?
Key point: Identical questions are what make answers comparable.
Decision-ready RFQ checklist
- Mandatory requirements separated from preferences
- Capacity stated with product, conditions and measurement basis
- Every interface and utility connection defined with an owner
- FAT and SAT criteria, methods and responsibilities included
- Compliance documentation requested; applicable rules confirmed locally
- Installation, commissioning, training, documentation, spares, service and warranty specified
- Incoterms® rule, currency and payment schedule stated
- Common commercial schedule and evaluation criteria shared with all bidders
Common costly mistakes to avoid
- Sending a supplier's own specification to its competitors
- Stating capacity without product properties or operating hours
- Leaving utilities and civil works as 'by others' without naming who
- Omitting acceptance tests, then negotiating them after award
- Comparing bids with different delivery terms or currencies
- Choosing on quoted price before normalizing exclusions

Frequently asked questions
How many suppliers should receive the RFQ?
Enough to create real comparison without overwhelming evaluation. Many buyers aim for three to five qualified suppliers, but the right number depends on the market and the complexity of the scope.
Should the RFQ specify a design or a performance?
Prefer performance wherever possible, with mandatory constraints stated clearly. Specify a design only where compatibility or regulation requires it.
What is bid normalization?
Adjusting each bid to the same scope, terms and basis — by estimating the cost of exclusions and aligning delivery terms and currency — before comparing prices.
Is the lowest normalized bid the best choice?
Not automatically. Score technical fit, delivery time, verifiable references and risk alongside the normalized price.
