Specification Sales: How to Get Technical Products Specified

Specification is often talked about as though it were an architect's activity that manufacturers hope to benefit from. That is a narrow view. Specification is a commercial process that runs across engineered and technical products of every kind — structural systems, components, control systems, materials, plant and equipment — and it is influenced by a wider set of people than architects alone: consulting engineers, technical buyers, main contractors' technical departments, OEM design teams and end-user engineering functions.

Getting specified matters because it changes the shape of the sale. A product named in a specification is the default; every alternative has to argue its way past it. That is worth a great deal of margin protection and competitive advantage, but only if the business behind the product understands that specification is won upstream, well before the tender, and has to be actively defended once it is in place.

This article sets out specification selling as a commercial discipline: who actually influences a specification, how the process runs from first contact to defended position, where technical businesses lose specifications they thought were secure, and how to build a repeatable process around it rather than relying on occasional, unmanaged relationships.

What does 'specified' actually mean for a technical product?

A product is specified when it, or a tightly defined equivalent, is named in the documentation that governs what gets bought on a project or programme. That documentation might be an architect's specification, a consulting engineer's technical schedule, an OEM's approved parts list, a main contractor's preferred supplier list, or an end user's engineering standard. The mechanism differs by sector, but the commercial effect is the same: whoever is specified starts every subsequent conversation from a position of advantage.

Being specified is not the same as being ordered. A specification can be softened to 'or equal approved', substituted at procurement, value-engineered out, or quietly dropped if nobody defends it. Businesses that treat specification as the finish line rather than a stage lose work they believed was secure.

Who actually influences a specification?

The influencer is rarely one person, and it is rarely only the person with the job title that suggests authority. A realistic map usually includes several of the following, and the mix depends entirely on the market.

Specification window

The period during which a design or standard is genuinely open to influence — before a decision has hardened into habit, precedent or a signed-off document. Approaching an influencer after the window has closed produces polite meetings and no commercial result.

Why do technical businesses struggle to get specified?

Three patterns account for most of it. First, activity is aimed at buyers rather than specifiers — the sales effort goes into the tender stage, by which point the specification is already fixed and the conversation is about price against a named or equivalent product. Second, technical credibility is assumed rather than built: data sheets are sent, but nobody has done the design support, sample testing or site-specific engineering work that actually earns a specifier's confidence. Third, there is no process for finding out which projects and programmes are at the design stage now, so specification activity is opportunistic rather than planned.

How does a specification sales process actually run?

The process is sequential and each stage has a distinct purpose. Skipping a stage — jumping from first contact straight to asking for a specification — is the most common reason specification activity produces meetings but not results.

1. 01Identify programmes and projects at design or standard-setting stage, before the specification window closes.
2. 02Map who actually influences the specification on that project or programme, not just who holds the buyer relationship.
3. 03Build technical credibility with that influencer through relevant data, design support, samples or case evidence — not a generic product pitch.
4. 04Secure a named or tightly defined specification, and get it documented rather than verbally agreed.
5. 05Track the specified project or standard through to procurement, because value engineering and substitution happen after specification, not before it.
6. 06Defend the specification actively when challenged, with the same technical evidence that won it in the first place.

What is the difference between construction specification and engineering specification?

Construction specification tends to run through named documents at defined project stages, with a relatively well-understood cast of architects, engineers and contractors. Engineering and industrial specification is often less formal and more durable: a component qualified into an OEM's design, or a material written into an end user's engineering standard, can stay specified for years without a single further sales conversation, but is also far harder to dislodge a competitor from once it is in place. The commercial implication is the same in both cases — the effort has to happen while the specification is still open, and the value of holding it justifies sustained investment in the relationship.

A worked scenario

A manufacturer of a technical fixing system supplies mainly through merchants and reacts to tenders as they appear, winning roughly one in six on price. Reviewing twelve months of lost tenders shows the same competitor's product named as the basis of design in most of them, because that competitor's technical team has been supporting the relevant consulting engineers directly for two years. The manufacturer redirects part of its business development effort away from tender response and towards identifying projects at design stage, supporting the same class of consulting engineer with load data and site-specific technical input, and tracking those relationships through to specification. Within a comparable period, the tender win rate on projects where they held the specification themselves is materially higher than on projects where they were simply invited to quote — an entirely expected result of competing from ahead rather than behind.

Common mistakes in specification sales

• Treating specification as a marketing output (data sheets, CPD sessions) rather than a tracked commercial process with named projects and outcomes.
• Approaching specifiers only after the design has effectively been fixed.
• Assuming a specification wins the order automatically, and withdrawing attention until the tender lands.
• Failing to identify who genuinely influences the specification, and investing in the wrong relationship.
• No record of which projects are specified, at what stage, or what needs to happen to defend the position.
• Reacting to a substitution challenge only after it has already succeeded.

How do you measure whether specification activity is working?

What should you do next?

Start by mapping which of your target markets actually run on specification, who influences it, and how far in advance the specification window opens relative to order. Build a short list of live projects or programmes at that stage now, and resource the relationship-building and technical support work needed to win a named position — then put a tracking discipline in place so a specification is followed through to order rather than assumed to be safe once granted.
