When a retailer proposes a scan-based trading arrangement, they are proposing that you fund the stock in their stores until a shopper buys it. It is frequently a good deal. It is never a free one.
This guide explains how scan-based trading works, how it differs from consignment and sale-or-return, what the supplier gains and gives up, whether the model applies in Indian retail, and what it takes operationally to manage inventory you own inside a store you do not control.
What is Scan-Based Trading?
Scan-based trading (SBT), also called pay-by-scan, is a distribution model in which the supplier retains ownership of goods after delivery to the retailer. The retailer pays only when an item is scanned at the point of sale. Until that scan, the stock sits on the retailer’s shelf but on the supplier’s balance sheet.
The model depends on shared data. The retailer’s POS system reports each scan back to the supplier, generating itemised settlement and giving the supplier store-level visibility of what is actually selling.
Consignment vs Scan-Based Trading vs Sale or Return
These three terms are used interchangeably and should not be. They share the same ownership principle and differ in how and when money moves – which is the part that affects a supplier’s cash flow.
| Consignment | Scan-based trading | Sale or Return (SOR) | |
|---|---|---|---|
| Ownership | Supplier, until sold | Supplier, until scanned | Supplier, until sold |
| Settlement trigger | Periodic stock reconciliation between visits | Each scan at the till | Agreed review period |
| Invoice form | Lump invoice for the interval’s movement | Itemised, typically aggregated daily | Statement at period end |
| Data required | Physical count at each visit | EDI-linked POS feed | Retailer sales report |
| Unsold stock | Remains, or is collected | Remains until sold or withdrawn | Returned or carried forward |
| Common where | Traditional trade, specialist retail | US grocery and DSD categories | Indian modern trade, e-commerce, fashion, beauty |
The practical distinction is speed and granularity. Consignment tells you what moved between two visits. SBT tells you what moved this morning, at this store, at this price. SOR sits between the two and is the arrangement Indian brands most commonly encounter.
How Scan-Based Trading Works, Step by Step
- Agreement : Supplier and retailer settle terms in advance – pricing, promotional treatment, shrink liability, settlement frequency, and how disputes are resolved.
- Delivery : Goods are delivered to the store or distribution centre. No invoice is raised and no payment is due.
- Shelf placement : The stock is merchandised onto the shelf, priced and positioned. Ownership remains with the supplier throughout.
- Sale : A shopper buys the item and it scans at the till.
- Data transmission : The scan is reported back to the supplier, usually via EDI.
- Settlement : The retailer pays for scanned units, less the agreed margin, on the agreed cycle.
- Reconciliation : Periodically, physical stock is counted against scanned sales and delivered quantity. The difference is shrink – and who absorbs it is the term that matters most.
What the Retailer Gains
- No upfront inventory cost : Working capital that would sit in stock is freed for other use.
- Reduced inventory risk : Unsold stock is not a write-down.
- Greater willingness to range new products : With no purchase risk, retailers will trial products they would otherwise decline – which is genuinely valuable to a supplier launching a range.
- Lower handling burden : Where the supplier services the shelf, store labour is released for other tasks.

What the Supplier Gains
- Access and range expansion : The single strongest argument for accepting SBT. Retailers list products under consignment that they would not buy outright, which can open distribution that is otherwise closed to a challenger brand.
- Store-level POS data : Visibility of what sells, where and when, at a granularity most Indian suppliers never obtain in any other way. This alone can justify the arrangement.
- Control of the shelf : Because the supplier services its own stock, it controls facings, placement and replenishment rather than relying on store staff.
- Preferred-vendor positioning : Shared risk tends to produce a closer commercial relationship and earlier involvement in category decisions.
- Faster settlement than consignment : Per-scan invoicing shortens the cash cycle relative to interval-based reconciliation.
What the Supplier Takes On
This is the half most guidance omits, and the half a finance function will ask about first.
- Working capital across every stocking outlet : Stock in three hundred stores, unpaid until scanned, is a balance sheet commitment. Model it before agreeing store counts, not after.
- Shrink, damage and expiry : Theft, breakage and date-expired stock occur in a store the supplier does not staff. Where liability sits is the most negotiated and most disputed clause in any SBT agreement.
- Replenishment responsibility : Availability becomes the supplier’s problem. An empty facing is lost revenue the retailer has no financial reason to prevent.
- Reconciliation cost and dispute risk : Reconciling delivered, scanned, damaged and returned units is continuous administrative work, and disagreement over quantities is routine rather than exceptional.
- Dependence on the retailer’s data accuracy : Mis-scans, till errors and unrecorded shrink all resolve into supplier losses. You are settling against numbers you cannot independently verify unless you generate your own evidence.
- Systems burden : EDI integration, inventory tracking by location and ownership, and settlement reconciliation all require capability the supplier must build or buy.
Does Scan-Based Trading Work in India?
Why classic SBT is rare in Indian retail
Scan-based trading in its full form requires three things, point-of-sale scanning at every outlet, retailer willingness to share SKU-level POS data with suppliers, and EDI infrastructure connecting the two.
In India, the first is absent across most of the trade – the majority of outlets are general trade kirana and standalone stores with no POS to scan from. The second is uncommon even in modern trade, where store-level sales data is treated as commercially sensitive. The third is limited to larger organised players.
So a brand reading about SBT in international guidance and expecting to implement it across an Indian distribution footprint will be disappointed. The model does not port.

Sale or Return: the model Indian brands actually sign
What does exist here, widely, is Sale or Return. The brand ships stock to a retailer or marketplace, ownership is retained, and payment is made only for units sold at the end of an agreed period. Unsold units are returned or carried forward.
SOR is established in Indian e-commerce and modern trade, and is common in fashion, beauty, books, electronics accessories and premium consumer goods – categories where demand is hard to forecast and retailers resist purchase risk.
The commercial substance is the same as SBT the brand funds the stock and carries the risk. What differs is settlement mechanics and data granularity. The obligations set out above apply in full – and the reconciliation problem is worse, because settlement rests on a periodic retailer report rather than a per-scan feed.

Quick commerce and shifting inventory ownership
Quick commerce is renegotiating inventory ownership at speed. As platforms expand assortment across thousands of dark stores, brands are increasingly asked to hold stock in locations they cannot visit, cannot audit and cannot merchandise, with availability varying by pincode.
For a brand, this compounds the core SOR problem, ownership without visibility. Before agreeing to platform-side consignment terms, establish what stock-level reporting you will receive, at what frequency, and what recourse exists when reported and actual stock diverge.
Scan-Based Trading Software and Systems
The software category serving SBT is vendor-managed inventory and EDI integration. Platforms in this space ingest retailer POS feeds, drive replenishment against actual sales, and automate settlement and reconciliation.
What to establish when evaluating:
- Which retailers it already connects to : EDI integration is retailer-specific. A platform without an existing connection to your chain is a project, not a purchase.
- Settlement and reconciliation handling : Whether it generates itemised settlement, tracks shrink, and produces a dispute-ready audit trail.
- Ownership-aware inventory tracking : Stock must be tracked by location and by owner, which standard inventory systems frequently cannot do.
- What it does not do : This is the important one. VMI and SBT software reports what the POS feed says. It does not verify that the shelf is stocked, that the product is correctly positioned, or that reported shrink is genuine. Vendors in this category say so themselves – suppliers own inventory performance but generally lack the means to actively manage it. The software is the visibility layer. The store visit is a separate problem.
Before You Sign: What to Negotiate
- Shrink liability and its ceiling – Who absorbs it, at what percentage, and what evidence is required to contest a shrink claim.
- Settlement frequency and terms – Daily, weekly or monthly, and the payment window after each cycle.
- Data access – What POS or sales data you receive, at what granularity and frequency, and in what format.
- Store count and phasing – Working capital scales directly with outlets. Phase the rollout rather than committing to a full estate at signature.
- Who merchandises the stock – If it is you, that is a field cost to budget. If it is the store, expect availability to be worse and set the expectation accordingly.
- Reconciliation process and dispute resolution – How counts are conducted, how often, who attends, and what happens when the numbers disagree.
- Damage, expiry and withdrawal – Who bears date-expired stock, and on what notice you may withdraw slow-moving lines.
- Exit terms – How the arrangement ends and how remaining stock is valued and recovered.
The Operational Reality of Owning Stock You Cannot See
Sign an SBT or SOR agreement and a new operational obligation arrives with it. You now own inventory distributed across stores staffed by people who do not work for you and have no financial interest in whether your stock sells.
- Nobody replenishes your shelf unless you do, Store staff prioritise stock the store has paid for. Yours is not that stock.
- Shrink claims arrive without evidence, Reported losses are difficult to contest without independent documentation of what was on the shelf and when.
- Expiry becomes your write-off, Date-sensitive stock left unrotated is a supplier loss, and rotation is a physical task somebody has to perform.
- Reconciliation is only as good as the count. A count you did not witness is a number you are accepting on trust.
- Availability determines the return. The entire economic case for SBT depends on the stock selling. Every hour a facing sits empty, your capital is deployed and earning nothing.
How PPMS Manages Supplier-Owned Inventory In-Store
Software tells you what the retailer’s POS reported. It cannot tell you what is on the shelf. PPMS operates the layer that can.
Merchandising your own stock
PPMS merchandisers service supplier-owned inventory during store visits – moving stock from backroom to shelf, maintaining facings and planogram position, rotating date-sensitive lines, and flagging replenishment before a facing empties. Under a consignment model this is not a visibility exercise; it directly protects the capital you have deployed.
Independent evidence for reconciliation
Every visit is captured through FRAMe, our proprietary field application, with geo-tagged and time-stamped photographs of shelf and stock condition reaching your dashboard the same day. FRAMe‘s back-end auditing module validates and scores submitted work independently of the person who performed it.
For an SBT or SOR arrangement, this is the evidential base that shrink and reconciliation disputes turn on. A photographed, geo-verified record of what was physically present, when, is a materially stronger position than accepting a retailer’s count.

Frequently Asked Questions
1. How does scan-based trading work?
The supplier delivers stock but retains ownership. The retailer pays only when an item is scanned at the till, with the scan reported back via EDI and settlement generated per item. Until the scan, the stock sits on the retailer’s shelf and the supplier’s balance sheet.
2. What does “scan” mean in retail?
It refers to the moment a product is read at the point of sale. Under scan-based trading, that moment is also the moment ownership transfers and payment becomes due – which is why the model is also called pay-by-scan.
3. What are scan sales?
Sales recognised only when the item scans at the till. Stock delivered but not yet scanned is not a sale for the supplier, regardless of how long it has been in the store.
4. What is the difference between consignment and scan-based trading?
Both leave ownership with the supplier. They differ in settlement: consignment reconciles at intervals and produces lump invoices for the period’s movement, while scan-based trading settles per scan and produces itemised invoices, typically aggregated daily. SBT is faster and more granular, and requires POS data integration that consignment does not.
5. What is Sale or Return, and how does it differ from SBT?
SOR is the model most commonly used in Indian modern trade and e-commerce. The brand retains ownership and the retailer pays for units sold at the end of an agreed period, returning or carrying forward the rest. The commercial substance matches SBT; settlement is periodic rather than per-scan, and data granularity is lower.
6. Is scan-based trading used in India?
Rarely in its full form, because it requires POS scanning at every outlet, retailer willingness to share SKU-level data, and EDI infrastructure – none of which is widespread in Indian retail. Sale or Return is the equivalent arrangement Indian brands actually encounter.
7. What are the risks of scan-based trading for suppliers?
Working capital tied up across every stocking outlet, shrink and damage liability in stores you do not staff, responsibility for replenishment and availability, ongoing reconciliation cost, dispute risk over quantities, and dependence on the accuracy of the retailer’s scan data.
8. Who is responsible for stocking the shelf under scan-based trading?
Usually the supplier, and it is worth confirming in the agreement. Store staff prioritise inventory the store has paid for, so supplier-owned stock left to store replenishment tends to show worse availability – which directly undermines the economics of the arrangement.
