Product contracts vs. service contracts: what changes in the proposal
Buying a thing and buying work are evaluated differently. How specs, labor, past performance, pricing and risk shift between a product bid and a service bid.
A proposal team that has written fifty service bids can still lose its first product bid, and the reverse is just as common. The documents look alike, with the same sections and the same instructions to offerors, but the buyer is asking a different question in each.
When the government buys a product, it is asking: does this thing meet the specification, arrive on time, and cost the least for what it is? When it buys a service, it is asking: will these people, organized this way, deliver an outcome we can only partly describe in advance? Most of what changes in the proposal follows from that difference.
How the requirement is written
A product requirement is usually a specification: dimensions, performance, standards, quantities, delivery dates. Either the item conforms or it does not. The proposal's job is to prove conformance clearly and make it easy to check.
A service requirement comes in one of three shapes, and the shape tells you how much room you have:
- A statement of work (SOW) says what tasks to perform and often how. Little room for a better approach; win on execution and price.
- A performance work statement (PWS) says what outcome is required and how it will be measured, and leaves the method to you. FAR Part 37 states a preference for this performance-based approach. Your method is now part of what is evaluated.
- A statement of objectives (SOO) gives the goals and asks you to write the PWS yourself. The approach is the proposal.
Read which one you have before you plan a single section. A team that answers a SOO the way it answers a SOW hands in a compliant document that says nothing about how it will succeed.
What the evaluators score
Both kinds of acquisition can be decided on lowest price technically acceptable (LPTA) or on a best-value tradeoff, where a higher-rated, higher-priced offer can win. In practice the balance differs:
| Product | Service | |
|---|---|---|
| What "technical" means | Conformance to the specification, test data, certifications | Approach, staffing, management plan, transition |
| Past performance | Delivery record, quality escapes, warranty history | Relevance of similar work, at similar scale, for similar buyers |
| Key personnel | Rarely evaluated | Often named, with résumés and commitment letters |
| Price | Unit prices, quantity breaks, delivery and logistics | Labor categories, rates, hours, escalation, and their realism |
| Main risk to the buyer | A defective or late item | Turnover, a weak transition, scope creep |
For a product, a technical volume should be short, exact and traceable to the spec. For a service, the technical volume is where the competition happens, because two companies with the same price can propose very different ways to staff and run the work.
Pricing a service is pricing people
A service price is built from labor categories, rates and hours. Evaluators check more than the total. A realism review asks whether the hours and rates you proposed could actually deliver the work; an offer priced too low can lose for exactly that reason, because it signals either a misunderstanding of the requirement or a plan to cut staff after award.
Service contracts also carry labor rules that product contracts do not. Many service contracts are covered by the Service Contract Labor Standards (formerly the Service Contract Act), which set minimum wages and fringe benefits for covered employees by locality. A price that ignores the applicable wage determination is not a low price; it is a noncompliant one.
A product price has its own traps: the Trade Agreements Act and Buy American rules on where an item comes from, shipping terms, and warranty costs that belong in the price rather than in a footnote.
Past performance means different things
For a product, the strongest past performance is evidence of consistent quality and on-time delivery of the same or similar item. For a service, relevance is judged on scope, size and complexity: did you do this kind of work, at this scale, for a similar customer? A long record of small help-desk contracts does not count for much on a large enterprise IT services bid, however good it was.
That is why the decision to bid on a service contract depends so heavily on which of your past contracts you can cite, and how close each one is to this requirement.
How performance is managed after award
The buyer's view of risk shapes the whole proposal. For a product, the government inspects and accepts deliveries under its quality assurance clauses (FAR Part 46). For a service, it usually writes a quality assurance surveillance plan (QASP) that says how it will measure your performance against the PWS standards.
Write the service proposal with the QASP in mind. If the PWS says response times will be measured monthly, the proposal should say how you will hit them, how you will know before the customer does when you are slipping, and what you will do about it.
Commercial items blur the line
FAR Part 12 covers commercial products and commercial services, bought with simpler procedures and contract terms closer to private-sector practice. Software subscriptions, cloud services and many professional services are commonly bought this way. A commercial buy still asks the product or service question underneath; it just asks it with less paperwork, and often with more weight on price and published terms.
A short checklist before you plan the response
- Name the shape. Specification, SOW, PWS or SOO? That decides how much of the proposal is approach.
- Find the basis of award. LPTA or tradeoff, and the relative weight of technical, past performance and price.
- List what is evaluated about people. Key personnel, résumés, letters of commitment, clearances.
- Check the labor rules and sourcing rules that apply to the price.
- Pick your past performance early. If you cannot name three relevant references now, the bid decision should account for it.
The difference in one line
A product proposal proves the thing meets the spec at the best price. A service proposal proves these people, organized this way, will deliver an outcome, at a price that makes that believable. Decide which one you are writing before you write it.
