Channel loyalty
How manufacturers can see secondary and tertiary sales
Most manufacturers know what they sold to distributors and little after that. What secondary and tertiary sales are, and the ways to see them, from distributor reports to scans in the channel.
In short
Primary sales are from the manufacturer to its distributors; secondary sales are from distributors to retailers and dealers; tertiary sales are from retailers to the end user or the trade professional who fits the product. Manufacturers see primary sales in their own systems, secondary sales mostly through distributor reports, and tertiary sales rarely at all. The most reliable way to see past the first tier is a record made where the product moves: a scan of a unique code at the counter, the workshop or the site, linked to who scanned it.
Ask a manufacturer what it sold last month and it can answer to the unit. Ask where those units are now, which shops sold them and who used them, and the answer is usually an estimate. The gap between what was shipped and what was sold is where stock builds up, where competitors win counters and where trade spend disappears.
This guide explains the three levels of sales, why the later two are hard to see, and how the main ways of measuring them compare.
What are primary, secondary and tertiary sales?
| Level | From and to | Who usually records it | Typical source | Typical delay |
|---|---|---|---|---|
| Primary | Manufacturer to distributor | The manufacturer | Its own ERP and invoices | None |
| Secondary | Distributor to retailer, dealer or sub-dealer | The distributor | Distributor reports or a distributor management system | Days to weeks |
| Tertiary | Retailer to end user or trade professional | Often nobody | Audits, surveys, claims or scans | Weeks, or never |
Some industries use slightly different terms. "Sell-in" usually means primary sales, and "sell-out" means sales out of the channel, to the end user. The idea is the same: the further the product travels from the factory, the less the manufacturer knows.
Why are secondary and tertiary sales hard to see?
- The data belongs to someone else. Distributors and retailers record their own sales, in their own systems, and share what they choose.
- Reports arrive late and incomplete. By the time a monthly distributor report is checked, the month is over.
- Incentives can distort the numbers. When schemes pay on reported sales, some reports will be generous.
- The channel is wide. A brand may have hundreds of distributors and tens of thousands of retailers, many of them small and not digital.
- The person who decides is not in any system. The mechanic, electrician or painter who chose the product does not appear on any invoice.
What are the ways to measure sales past the distributor?
| Method | What it shows | Strengths | Limits |
|---|---|---|---|
| Distributor reports | Secondary sales, as reported | Simple; covers all distributors who report | Late; incomplete; can be shaped by schemes |
| Distributor management system | Secondary sales from distributor invoices | More complete and timely than reports | Needs every distributor to use it; says little about tertiary sales |
| Retail audits and field surveys | Stock and sales at sampled shops | Independent; can cover competitors | Samples only; expensive; periodic |
| Invoice uploads and claims | Purchases by retailers or the trade | Direct evidence of a transaction | Slow to check; easy to fake; heavy for participants |
| Unique codes scanned in the channel | Where each unit was sold, fitted or used, and by whom | Unit level; close to real time; tied to a person and place | Covers only units that are scanned, so participation matters |
Most brands combine methods. Distributor data covers volume; scans in the channel show where the product actually went and who chose it.
What can scan data show?
When each unit carries a unique code and the people who sell or fit it scan it, every scan records a product, a person, a place and a time. Over weeks, that shows:
- Where stock sits. Which areas and counters move the product and which hold it.
- Who sells and fits it. The retailers, mechanics, electricians and painters behind the sales.
- Which products move. Sales by product and pack size, by area.
- Where the brand is losing. Counters whose scans drop while demand in the area holds, which often means they have switched to a competitor.
- Whether schemes work. Sales before, during and after a scheme, in areas with and without it.
What are the limits of scan data?
Scan data only covers the units that are scanned. If only half of mechanics take part, the data shows half the picture, and probably the more engaged half. Three things help:
- Give each role a reason to scan, usually a reward paid quickly.
- Track participation alongside sales, so a fall in scans is not mistaken for a fall in sales.
- Compare with primary and secondary data, so gaps stand out.
How to start measuring sell-out
- Pick one category and one region where the brand most needs visibility.
- Put a unique code on each unit, linked to product and batch at the time of printing.
- Decide who scans and why, whether counter, mechanic, electrician or painter, and what each earns.
- Map the distribution tree, so each scan can be linked to the distributor and retailer that supplied it.
- Build a few views that people will use, such as sales by area, counter and product, and counters at risk.
- Review monthly, and expand once participation is steady.
Rewards are what make people scan, so programme design and visibility go together. How to build a dealer loyalty programme and how to run a mechanic loyalty programme cover that side.
What to measure
- Scan coverage. Scanned units as a share of units shipped into the area.
- Active counters and trade professionals, monthly.
- Sales by area, counter and product, and how they change.
- Counters at risk. Those whose scans are falling.
- Days from dispatch to scan, which shows how long stock sits in the channel.
Where Rewardix fits
Rewardix ties every reward to a verified scan at the counter, the workshop or the site, so the brand sees sell-out past the distributor by region, counter and SKU without waiting for distributor claims data. Scan data also shows which counters are slowing while demand holds, while there is still time to act. See the platform page, or the fasteners page, where stock moves through several tiers of distribution.
Frequently asked questions
What is the difference between secondary and tertiary sales?
Secondary sales are sales from a distributor to a retailer or dealer. Tertiary sales are sales from that retailer to the end user, or to the trade professional who fits the product, such as a mechanic or electrician. Manufacturers usually see secondary sales through distributor data, and tertiary sales rarely without a way to record them at the counter or on site.
Is a distributor management system enough to see sell-out?
A distributor management system improves the record of secondary sales, because it captures distributor invoices directly. It says little about what retailers then sell, or who uses the product. For that, a brand needs a record made at the counter or on site, such as a scan of a unique code on each unit.
How accurate is scan data as a measure of sales?
It is exact for the units that are scanned and blind to those that are not. Its accuracy as a measure of total sales depends on participation. Track the share of shipped units that are scanned in each area, and compare scan data with primary and secondary sales, so changes in participation are not read as changes in demand.
