The question I get asked most often
Sales directors at deep-tech companies ask me the same question in slightly different forms: "How do I make these cycles faster?" "Why does it take so long to get a PO?" "What can I do to accelerate the decision?"
The honest answer is: you can compress the cycle at the margins, but you cannot fundamentally change its length — not in any way that matters. And spending energy trying to is often counterproductive. Understanding why takes about five minutes, and it changes everything about how you manage your pipeline.
What the buyer is actually deciding
When an OEM buyer selects a component supplier, they are not making a purchasing decision. They are making an engineering decision with procurement consequences. The component gets designed into the product architecture. The PCB layout is optimised around its footprint. The software stack is written to its interface. The manufacturing process is built around its handling requirements. The quality system references its specifications. The supply chain is structured around its lead times and packaging.
Changing that component mid-production — after it's been designed in — is extremely expensive. It requires re-qualification of the affected subsystems, potentially new regulatory submissions, retraining of manufacturing staff, renegotiation of supply terms, and in some sectors (automotive, medical, aerospace) it triggers a formal change control process that can take 12-18 months by itself.
Given this, the caution that characterises OEM procurement is not bureaucratic slowness. It is entirely rational risk management in response to a decision with a decade of consequences. They are not being slow. They are being appropriately careful about a 7-10 year commitment.
The cycle length is a function of what's being decided, not how well you're selling.
The structural factors that set the floor
Even in the best case — qualified supplier, enthusiastic champion, budget available, no competitive alternative — an OEM sales cycle has a structural minimum driven by the buyer's internal processes:
Technical evaluation: Most OEM buyers will not approve a new component without an evaluation period. Even if your product is perfect, they need to run it in their environment, integrate it into their test setup, and confirm performance under their conditions. This typically takes 3-6 months for a serious evaluation.
Supplier qualification: After the technical evaluation, the supplier qualification process begins. This involves financial due diligence, quality system audit, supply chain risk assessment, and legal review. Depending on the sector and the buyer's internal processes, this takes 3-9 months.
Design-in: The component then needs to be designed into the product — PCB layout, firmware integration, mechanical integration depending on the component type. This is the engineering team's work and it operates on engineering timelines, not sales timelines. 3-12 months is typical.
Production ramp: Once the design is complete, there's typically a pilot production run before full production begins. This is another 3-6 months.
Add these up and you have a structural minimum of 12-30 months from first contact to first production purchase order, even in a smooth, well-managed deal with a motivated buyer. This is not a negotiating position. It's physics.
What you can actually influence
You cannot compress the buyer's internal qualification process. You cannot make their procurement committee meet more frequently. You cannot accelerate their engineering design schedule or their product roadmap decisions. You cannot make their regulatory submission process faster.
What you can influence is your position within that process — and that matters enormously. The difference between winning and losing in OEM markets is rarely about closing technique. It's about where you are in the evaluation when the formal process begins.
Specifically, you can influence: whether you're included in the evaluation at all (which requires awareness and relationships built before the evaluation starts), how your product is positioned relative to alternatives (which requires understanding the evaluation criteria before they're set), how smoothly the qualification process goes (which requires preparation and relationships with procurement, not just R&D), and how quickly design-in proceeds (which requires proactive application engineering support).
The salespeople who appear to "close faster" in OEM markets are usually not compressing the cycle — they're entering it earlier, at a point where they can shape the evaluation before the criteria are formalised. Entry point is everything.
The pipeline management implications
If you accept that cycle length is structural, your approach to pipeline management needs to reflect that reality in several ways.
Time-to-qualify matters more than close rate. In a 24-month average cycle, the most important metric is how quickly you move from "identified opportunity" to "evaluation started." Every month of delay at the front end is a month of delay at the back end. The salespeople who obsess over close rates in OEM markets are measuring the wrong thing.
Early-stage and late-stage deals need completely different management. An early-stage deal (trigger identified, initial contact made) needs relationship investment, technical credibility building, and positioning work. A late-stage deal (evaluation complete, in commercial qualification) needs procurement relationship management, documentation support, and internal champion coaching. Applying the same management style to both is inefficient and often counterproductive.
Forecast accuracy requires knowing where you are in the buyer's process. A deal in "negotiation" in your CRM may be in "preliminary supplier review" in the buyer's process — which means it's months earlier than it looks in your forecast. The only way to forecast accurately in OEM markets is to know the buyer's process well enough to map your stages to theirs, not just track your own activities.
Pipeline coverage needs to be much larger than in shorter-cycle businesses. With 18-30 month cycles and meaningful failure rates at each stage, you need 4-6x pipeline coverage to hit your annual number. Most OEM sales organisations are chronically underpipelined because they apply coverage ratios designed for SaaS businesses.
How to talk about this with leadership
One of the hardest parts of managing OEM sales is explaining cycle length to leadership who have experience in shorter-cycle businesses. The temptation is to present every deal as "nearly closed" to manage expectations — which creates exactly the forecasting problems described above.
A more effective approach is to shift the conversation from "when will this close?" to "where are we in the buyer's process?" If you can map your deals to the buyer's internal stages — technical evaluation, supplier qualification, design-in, pilot production — you can have a much more honest conversation about realistic timelines that is grounded in buyer behaviour rather than your own wishful thinking.
This also gives you a more defensible position when deals take longer than expected. "We're in the supplier qualification stage and their procurement team is running a parallel review of two other suppliers" is a much better explanation than "the deal is taking longer than expected" — because it tells leadership what's actually happening and what would need to change to move things forward.
The conclusion that actually helps
Stop trying to make OEM cycles faster. Start trying to enter them earlier, position yourself better at each stage, and build enough pipeline to sustain your business while deals run their natural course. The organisations that win consistently in OEM markets have accepted the structural reality of long cycles and built their commercial operations around it — larger pipelines, longer planning horizons, more investment in early-stage relationship building, and better qualification processes to distinguish deals worth pursuing from deals that will never convert.
The ones that struggle are the ones applying short-cycle sales management to long-cycle markets — setting quarterly targets that don't align with deal timelines, underpipelining because coverage ratios are too low, and burning sales team credibility with leadership by overpromising on deals that are structurally months away from closing.
