Most aftermarket suppliers and manufacturers have strong visibility of one thing: sell-in. They know what they’ve shipped to distributors, buying groups, and motor factors. They know their own sales numbers by region, by account, by product line.
But sell-in data only tells half the story. It tells you what left your warehouse, not what’s actually moving at the point of sale. It doesn’t tell you whether your product is competitively priced in a given region, whether a competitor is gaining share in a category you dominate nationally, or whether a motor factor is sitting on excess stock of your product because demand has shifted.
What is sell-through data and why does it matter?
Sell-through data captures what actually happens at the motor factor level, real transactions between factors and their garage customers. This is the ground truth of the aftermarket. It shows which products are moving, at what price, in which regions, and at what velocity.
At Factor Sales, we aggregate anonymised sell-through data from motor factors across the UK. For suppliers, this creates a market-level view that’s simply not available from internal sales data alone. You can see not just your own performance, but the total addressable market for your categories, and your share of it.
How are leading suppliers using market intelligence?
The suppliers getting the most value from market intelligence are using it across three key areas:
- Range development: Identifying categories where market demand is growing but their product range has gaps. This turns range planning from a reactive exercise into a proactive growth strategy.
- Pricing strategy: Understanding how their products are actually priced at the factor level, not just the list price or the negotiated buy price, but the real street price. This insight is invaluable for renewal negotiations and promotional planning.
- Territory planning: Seeing regional performance at a granular level. A supplier might have strong national share in braking but discover they’re underrepresented in a specific region where a competitor dominates. That’s an actionable insight for their field team.
What does this mean for supplier renewals and negotiations?
Renewal season in the aftermarket has traditionally been a negotiation based on relationship, volume commitments, and rebate structures. Market intelligence changes the dynamic. When both parties can see objective market data, share of category, pricing benchmarks, regional performance, the conversation shifts from opinion to evidence.
Suppliers who arrive at renewals with a clear, data-backed view of the market are better positioned to justify their value proposition, identify mutual growth opportunities, and build longer-term partnerships based on shared visibility.
