Manufacturers: getting specified before the RFP comes out
By the time the RFP comes out, the game is mostly over. The decision was made months earlier, in the office of the person who wrote the spec, and most manufacturers were not there. That window is what decides your sales, not the bid.
- The specification window sits months before bids open and lasts a few weeks. It is the only moment your product can get into the spec.
- The person who specifies is not the person who buys. They are trying to reduce their professional risk, not to get the best price.
- Gartner measures that 67% of B2B buyers prefer a rep-free buying experience, in a survey of 646 buyers conducted in the fall of 2025.
- Bidding without being specified costs estimating time for a very low close rate, the share of bids that become sales. It is the worst-counted expense in this sector.
- The approved-equal clause is not an open door: it transfers to the engineer a verification job they have no reason to accept.

What is the specification window
The specification window is the period, upstream of an RFP, during which a designer writes the technical spec and chooses the products that will be named in it. It usually lasts a few weeks and closes well before the call for bids is published. A product that does not get in will later have to be defended as an equal, with a much lower success rate and a higher cost of sale.
When the decision is made
This article is written for manufacturers and distributors whose products go into projects designed by third parties: construction, industrial equipment, building mechanical systems, coatings, systems. It is about selling upstream, not about bidding.
A project's real calendar is longer than the one a manufacturer sees. The designer receives the mandate, studies the options, writes the spec, obtains the approvals, then the RFP comes out.
In a scenario with fourteen months between the mandate and bid opening, the specification window occupies about six weeks, nine months before the RFP. During those six weeks, the person writing compares products, reads data sheets and chooses the ones they will name.
Most manufacturers discover the project when the RFP comes out. They therefore arrive nine months too late for a decision already written, and they invest their sales effort at the moment it is worth the least.
This mechanic is invisible in reports. A company that tracks its close rate on bids never sees the projects where it was not specified, since it did not bid on them, nor the ones where the spec named a competitor. It believes it has a price problem when it has a calendar problem.
Who actually writes the spec
Treating the buyer and the designer as one person remains the costliest confusion in this sector.
The designer is an engineer, an architect, a technologist or a project manager. They do not pay for the product and do not order it. Their relationship with you is not commercial, it is technical, and they have no obligation to talk to you.
The buyer comes in later. They work with a spec already written, and their room to manoeuvre is limited to what that spec allows.
Two practical consequences. Your rep who visits the buyer arrives at the right place at the wrong time. And your sales tools, built to convince someone to buy, are of no use to the person who must decide to specify.
Gartner in fact measures that 67% of B2B buyers prefer a rep-free buying experience. One caveat on scope: the survey covers B2B buying in general, and it indicates a direction rather than identical behaviour among designers, whose relationship with suppliers follows other constraints.
What the specifier is looking for
They are not looking for the best product: they are looking to reduce their professional risk, and the whole file follows from that distinction.
An engineer who names a product engages their responsibility. If the product does not perform, does not ship on time or fails inspection, they answer for the choice to the client and sometimes to their order.
What they want is therefore precise: complete, verifiable technical data, up-to-date attestations and certifications, drawings they can integrate directly, confirmed availability, and a track record of comparable projects.
What does not interest them: your sales pitch, your competitive advantages, your company history. They do not read a product page like a buyer; they look for one precise data point and leave as soon as they have found it or seen that it is missing.
Your website bears the direct consequence: a product page built to sell fails with them, while a page built to be verified holds them. It is the same logic as product data, covered in our article on product data maturity.
The tools that make the difference
The downloadable guide spec. Specification text ready to drop in, in the format designers use. It is the most decisive tool in the file and the least common: you write the paragraph that names you yourself.
Technical files that can be used as is. Drawings, models, assembly details. A designer who has to redraw your product will pick the one they do not have to redraw.
Up-to-date, dated attestations. Certifications, test results, compliance with the applicable standards. An expired attestation on a website is grounds for immediate exclusion.
Comparable reference projects. Not your prettiest projects: the ones that look like theirs, with the constraints they face.
A reachable technical contact. Not a sales form. A number that lands on someone able to answer a calculation question the same day.
The first point deserves emphasis because it inverts the usual commercial logic. Supplying a guide spec means writing the text that wins for you yourself, and saving time for the person who decides. It is the best-returning investment in this entire sector.
What not being specified costs
The calculation runs on estimating time, and it surprises most management teams.
A technical bid means reading the spec, checking compliance, calculating quantities, getting supplier prices and producing the document. In a scenario, that represents about $2,800 of internal time.
Bidding on twenty RFPs where you are not specified therefore represents $56,000 a year, for a close rate that rarely tops 10% in that situation. The two sales won have to absorb the cost of the eighteen other bids.
Compare that amount to what producing the specification tools costs: a guide spec, clean technical files and up-to-date attestations represent a few dozen hours, invested once and reusable on every project.
The trade-off is never close, and it leads to an uncomfortable but profitable decision: stop bidding on RFPs where you are not specified, barring a specific reason, and reinvest that time upstream.
The approved-equal trap
The approved-equal clause looks like an open door, but it mostly transfers work.
When a spec names a product and adds that clause, it lets a bidder propose something else, subject to the designer's approval. In practice, the engineer must then verify your product, compare the data and stake their responsibility on a choice they did not make.
They have no reason to accept that extra work, especially on a short bid deadline. The approval rate for equals therefore stays low, and it depends almost entirely on how easy you make the verification.
What improves your odds, when you must take this route: a line-by-line comparison table with the named product, the matching attestations, and an answer within twenty-four hours. What reduces them: a sales sheet and a promise of equivalence without demonstration.
The lesson does not change: the equal remains an expensive catch-up, while the specification window remains the only route that costs little and pays durably.
What to establish before the next bidding season
These five questions move the sales effort from the bid to the moment the decision is made.
- On last year's bids, in how many cases were you named in the spec?
- What is your internal estimating cost per bid, and how many did you produce without being specified?
- Does a downloadable guide spec exist for your main products, in the format designers use?
- Are the attestations you publish online up to date and dated?
- If you stopped bidding without being specified, how much time would free up, and what would you spend it on?
The answer that holds up gives a share of bids where you were named and an estimating cost. A hollow answer talks about a price-competitive market. A vendor that proposes to raise your visibility with buyers without having asked who writes your specs is aiming at the wrong person at the wrong time.
Measuring your spec presence rate and building the specification tools is part of what we deliver in a paid audit.
What never gets delegated: the technical content of the guide spec, keeping the attestations up to date, and the decision to stop bidding without being specified. What gets delegated: measuring the spec presence rate, putting the technical files online, producing the content that answers designers' questions, and tracking projects upstream. A manufacturer that publishes a guide spec and files that can be used as is ends up named in projects it never heard about. A manufacturer that puts all its effort into the bid pays a high estimating cost to arrive nine months too late.
This point sits inside the plan described in the marketing plan and its budget.
Moving the sales effort to the moment it pays is at the heart of the Optimize the profitability of your digital campaigns goal.

Frequently asked questions about getting specified
How do you know whether you are specified?
Reread the specs of the RFPs you answered last year and count the ones that named you. That share is the most important indicator in your sector and almost no one tracks it. A low close rate with a low spec presence rate is a calendar problem, not a price problem.
What is a guide spec?
Specification text ready to drop in, written by you, in the format designers use. It describes the product in verifiable technical terms rather than sales arguments. It is the most decisive tool in the file: you write the paragraph that names you, and you save time for the person who decides.
Should you stop bidding without being specified?
Do the math before deciding. Twenty bids at $2,800 of estimating each represent $56,000 for a close rate that rarely tops 10% in that situation. The freed-up time, reinvested upstream with designers, generally produces more. Keep exceptions for strategic clients.
Is the approved equal a real possibility?
It is an expensive catch-up. The clause transfers to the designer a verification job they must do on a short deadline and stake their responsibility on. Your odds depend almost entirely on how easy you make it: a line-by-line comparison table, the matching attestations, an answer within twenty-four hours.
What content attracts designers?
Content that answers a precise technical question, not content that presents the company. A designer looks for a data point, finds it or sees that it is missing, and leaves. Publish the complete data, the assembly details, the special-constraint cases and the answers to the questions your technical service gets every week.
How long before you see an effect?
The cycle sets the delay. If the specification window sits nine months before the RFP, work started today produces its first effects a year later. That is long, and it is also what protects your position once won: your competitors face the same delay.
