How this guide was prepared. Last updated October 2026. It draws on Brandmovers' experience designing loyalty, promotions and receipt-validation programs for consumer brands, including the program examples cited below. It also draws on US consumer protection and privacy rules, each checked at its source. |
CPG brands build first-party data without retailer data by giving consumers a reason to identify themselves and share proof of purchase directly with the brand, commonly by uploading a receipt in exchange for points, entries or rebates, and by adding reasons to engage between purchases.
Consumer packaged goods brands sell through retailers, so the retailer sees the basket, and the shopper when they use a retailer loyalty account, while the brand sees shipments. Retailer loyalty programs, retail media networks and syndicated data give brands some visibility, but usually aggregated, delayed or on the retailer's terms. A direct program changes that: each verified purchase adds to a record the brand controls. This guide explains the data gaps CPG brands face, how receipt validation works and what it captures, which mechanics generate useful data, the legal and privacy rules that apply, how to measure the program and what to look for in a platform partner. The guide to CPG loyalty fundamentals covers program strategy more broadly, and the guide to building customer loyalty for CPG brands follows the full path from anonymous buyer to repeat customer.

CPG brands do not own the point of sale, so they usually cannot credit purchases automatically or see who bought, and every data point has to be earned directly from the consumer.
A hotel, airline or retailer captures each transaction at its own checkout and can credit a loyalty account without the member doing anything. A CPG brand sells to a retailer, which sells to the consumer. Three gaps follow:
A direct loyalty relationship does not replace retailer data. It adds verified, individual-level purchase records for the consumers who choose to take part.
A consumer photographs a receipt, the system reads it, checks that it includes a qualifying product and has not been used before, screens it for fraud and credits the reward.
Receipt validation has three stages:
The technical guide to receipt validation covers these steps in more detail, and the guide to receipt recognition benefits covers the business case.
Online and delivery orders arrive as emails or app screenshots rather than paper receipts, so confirm the program accepts digital receipts from the channels its consumers use. Unique codes printed on or inside packs are another route that avoids receipt reading, at the cost of packaging changes.
A receipt captures verified purchase facts for one transaction; over time, a member's receipts build an individual purchase history that aggregate retailer data cannot show.

Two limits matter. Receipts represent only the consumers who choose to take part, so members' purchases are not a sample of all buyers. And capturing the whole basket means collecting data about other brands' products and potentially sensitive purchases, which raises the privacy questions covered below.
One receipt is a transaction; a year of receipts from an active member suggests whether they are a regular buyer or a promotion responder, which products they buy and whether their buying is rising or falling. Receipts record what members choose to submit, not everything they buy, so treat the history as a strong signal rather than a complete record.
As receipts accumulate, a brand can:
The value compounds only if members keep submitting, so the mechanics need to give them reasons to engage between purchases.
Mechanics tend to generate useful data when they combine a purchase step with a reward worth the effort, and give members reasons to return between purchases.
Purchase-linked sweepstakes and instant wins need a free alternative method of entry, receipt and basket data is personal information with notice and consent duties, incentives for reviews must not depend on sentiment, and incentivized posts need disclosure.
This is general information, not legal advice.
Screen every receipt for reuse, editing and generation, watch for patterns across accounts, and scale checks to the value of the reward.
Image-editing and generative tools make fake receipts easier to produce, so visual review alone is not enough at scale. Controls include duplicate detection across accounts, checks for signs of editing or generation, consistency checks against known retailer formats, submission-velocity and shared-identifier checks across accounts, and caps on rewards per member per period. Hold high-value rewards for review, and give members a quick way to resubmit or appeal a rejected receipt, since overly strict checks turn honest buyers away. The guide to detecting and preventing loyalty program fraud covers controls in more depth.
Measure incremental sales with test and control markets or member holdouts, what each verified member costs and how much of your sales the program actually sees.
Look for accurate receipt extraction across major US retailers, layered fraud controls, loyalty and promotions on one member record, clear data ownership and promotions legal expertise.

Evaluation area |
What to ask |
What good looks like |
|---|---|---|
|
Receipt extraction |
How accurately are line items read and matched to products across the retailers your consumers use? |
Tested accuracy on your own products and retailers, with a clear process for unreadable receipts |
|
Fraud controls |
How are duplicates, edited receipts and coordinated accounts detected? |
Automated, layered checks with manual review for high-value rewards |
|
Basket data |
Does the platform capture all line items, and can capture be limited to what the program needs? |
Configurable capture, aligned with the privacy notice |
|
Loyalty and promotions |
Do sweepstakes, instant wins and rebates run on the same member record as the loyalty program? |
One member record, so every receipt updates the purchase history |
|
Data ownership |
Who owns the data, and can it be exported in a structured format? |
The brand owns and can export its data |
|
Promotions compliance |
Who drafts official rules, builds the AMOE and handles state requirements? |
In-house or dedicated promotions legal expertise |
|
Security |
Which independent audits cover the platform? |
Current third-party attestations such as SOC 2 Type II |
BLOYL™, Brandmovers' loyalty platform, includes OCR receipt validation, built-in fraud protection, a promotions builder for sweepstakes, contests, instant wins and bonus events that runs alongside the loyalty program, a dynamic rules engine, a rewards catalog of 100,000+ options and bidirectional CRM and CDP data flows. Its analytics include A/B testing against a control group. Brandmovers also has in-house legal for promotions and holds SOC 2 Type II and PCI DSS. See the loyalty platform overview for details.
CPG brands will not get individual-level data from retailers by default. A direct program built on receipt validation, with mechanics that give consumers reasons to engage between purchases, gives brands verified purchase histories for the consumers who take part. The data is only as good as the design: build the free entry route into purchase-linked promotions, handle basket data with notice, consent and restraint, control fraud, and measure incremental sales with test and control markets or member holdouts rather than counting members' purchases as lift.
