For most consumer packaged goods brands, the relationship with the end consumer is mediated by a retailer. The brand invests in advertising, shopper marketing, and trade promotions, but the till receipt belongs to the supermarket, not the manufacturer. The loyalty programme, if there is one, tends to belong to the retailer too.
That dynamic has real consequences for CPG brands. Without a direct relationship with consumers, there is no first-party data. Without first-party data, personalisation is impossible, campaign targeting is blunt, and it is extremely difficult to prove that any particular marketing investment actually changed purchase behaviour.
A well-designed CPG loyalty programme changes this equation. It creates a direct channel between brand and consumer, captures behavioural data that the retailer will never share, and builds the kind of ongoing engagement that turns occasional buyers into committed brand advocates. Getting it right takes strategic thinking, the right mechanics, and a technology platform that can operate across retail environments without friction.
Loyalty programmes in retail banking, hospitality, or airlines work because the brand controls the transaction point. When a customer buys a flight or uses a credit card, the brand knows immediately and can reward accordingly.
CPG brands do not usually have that luxury. Products are bought at dozens of different retailers, through multiple channels, in different formats. The brand rarely sees the transaction data directly. A CPG loyalty programme has to work around this structural reality, which means it needs its own mechanics for capturing proof of purchase and attributing consumer behaviour to the brand rather than the retailer.
The choice of mechanic is not just a technical decision. It shapes how many consumers will actually participate, what kind of data you will collect, and what your FMCG customer loyalty strategy can realistically achieve in the first 12 months. Starting with a clear picture of your consumer base and their digital behaviours is essential before committing to a mechanic. The table below sets out how the three main options compare.
| Mechanic | How it works | Consumer effort | Fraud exposure | Data richness |
|---|---|---|---|---|
| Receipt scanning | Shopper photographs a receipt and uploads via an app or microsite | Medium - requires keeping the receipt and a purchase-time or post-purchase step | Duplicate or manipulated images; needs robust image validation | High - retailer, basket value, and date, sometimes full basket detail |
| On-pack codes | A unique code inside or on the packaging is entered online to claim a reward | Low once the code is found, but discovery depends on pack design | Bulk code harvesting and resale; needs rate limiting and anomaly detection | Medium - confirms the specific product bought, not where or basket context |
| Retailer data partnership | A commercial agreement gives the brand access to purchase data through the retailer's own loyalty scheme (e.g. Sainsbury's Nectar360 in the UK) | None - happens automatically inside the retailer's existing programme | Low direct fraud risk, but data is shared on the retailer's terms | High but retailer-controlled - rich purchase history, gated behind commercial terms and GDPR clean-room rules |
Real programmes often combine more than one row. PG Tips ran its Cuppa Club as a pure on-pack scheme in the UK between 2013 and 2015, giving shoppers points from under the pack lid to redeem against merchandise. Brandfire's own on-pack work for Irish and UK brands, including Avonmore Cream's summer promotion and Hunky Dory's Movie Night campaign, paired a code on the pack with an instant digital reward rather than a slow-burn points balance, trading a smaller data footprint for a much lower barrier to entry.
Building a CPG loyalty programme is not without its complications, and understanding them upfront makes for better programme design.
| Barrier | Why it matters | How to manage it |
|---|---|---|
| Retailer relationships | Most major grocery retailers run their own loyalty schemes and can be wary of a supplier brand running a competing mechanic in-store | Get trade alignment before launch; a data-sharing arrangement like Sainsbury's Nectar360, which lets FMCG suppliers access shopper data through a privacy-safe clean room, shows what a relationship that benefits both sides can look like |
| Consumer effort | Receipt scanning and code entry both require an extra step after purchase, and every added step costs registrations | Keep the ask simple, make the reward compelling enough to justify it, and communicate the offer clearly at the point of sale |
| Fraud | On-pack codes are vulnerable to bulk harvesting and resale; receipts can be duplicated or manipulated | Build in validation logic, rate limiting, and anomaly detection from day one, the same controls behind Brandfire's receipt-upload work for Aldi and for SuperValu & Centra |
| Ongoing engagement | Getting consumers to register is the easy part; without a reason to come back, registration numbers look healthy while the programme functions as a one-off promotion | Plan the communication strategy for the second, third, and tenth purchase, not just the first |
On-pack execution is where most CPG loyalty programmes live or die. The packaging is the one touchpoint the brand controls regardless of which retailer the consumer buys from, which makes it uniquely valuable for driving programme registration and ongoing participation.
Effective on-pack mechanics are clear, prominent, and compelling. The consumer should be able to understand the offer in under five seconds: what they need to do, what they will get, and where to go to claim it. A QR code linking directly to the registration page reduces friction significantly compared to a URL the consumer has to type. The UK's Cuppa Club scheme (see above) ran for two years on this model, but a slow-building points balance is a harder sell than an instant reward, which is why more recent on-pack mechanics lean towards immediate gratification wherever the reward catalogue allows it.
The offer itself needs to justify the effort. A chance to win a prize worth entering once a year will not drive the repeat engagement that builds a loyalty database. Instant rewards, cumulative earning mechanics (buy X products to unlock Y), or milestone rewards for ongoing purchase are all more effective at sustaining participation. Brandfire's Hunky Dory on-pack campaign took the instant-reward route, pack codes unlocked a free movie download immediately rather than requiring accumulated points, and Glenisk's Disney Pixar movie partnership combined on-pack activation with in-store display and a digital experiential layer, giving families a reason to engage beyond the pack itself.
Packaging lead times in FMCG are long, which means on-pack loyalty mechanics need to be planned well in advance of the programme launch date, typically 12 to 18 months for a full product range update. For brands that need to move faster, a neck tag, a case sticker, or a shelf barker can deploy on-pack mechanics in a much shorter timeframe.
The link between on-pack creative and the digital registration journey needs to be seamless. Consumers who scan a QR code and land on a generic homepage, rather than a dedicated programme landing page, are highly likely to abandon before registering. Every step of that journey should be tested before launch.
The strategic value of a CPG loyalty programme is only partly in the rewards. The larger prize is the first-party data that the programme generates. In an era of cookie deprecation, tightening privacy regulation, and increasing scrutiny on third-party data sources, owning a direct relationship with your end consumers is a significant competitive advantage.
What data can you realistically collect? At a minimum, a receipt-based or code-based CPG programme will give you registration data (email, basic demographics), purchase data (what product, at what retailer, when), and engagement data (how the consumer interacts with your communications and digital content). A retailer data partnership, such as Sainsbury's Nectar360 arrangement with FMCG suppliers, can go further still, matching a brand's own customer data against the retailer's purchase history inside a GDPR-compliant clean room, without either side handing over raw customer records.
Over time, with the right platform and communication strategy, you can enrich that data significantly. Attitudinal data from surveys. Preference data from in-app interactions. Social amplification signals from share mechanics. Cohort analysis on what drives higher purchase frequency and what predicts churn.
This data has value beyond the loyalty programme itself. It feeds product development. It informs media buying. It builds the case for category growth conversations with retail buyers. According to a McKinsey study on FMCG data strategy, companies that use consumer data effectively to personalise experiences generate 40% more revenue than their peers.
An effective FMCG customer loyalty strategy begins with commercial objectives, not programme mechanics. Before deciding whether to use receipt scanning or on-pack codes, before choosing a reward catalogue, before briefing creative, you need to know what success looks like.
Growing your registered consumer database for future CRM activation is one possible goal. Driving trial of a new product variant is another. Defending market share against a competitor's own promotion is a third. Each objective shapes the programme differently.
Once objectives are clear, the strategy should address four things: the acquisition mechanic (how you get consumers to register), the retention mechanic (how you keep them engaged beyond the first purchase), the data strategy (what you will collect, how you will store it, and how you will use it), and the measurement framework (how you will know whether the programme is delivering commercial value).
The temptation in FMCG loyalty is to make the programme too complicated. Tiered earning structures, multiple reward types, gamification layers: these can work in high-frequency categories with engaged, digitally active consumers, but they add cost and complexity that is hard to justify in a category with low per-unit margins and infrequent purchase cycles. Start with a clear, simple mechanic. Add complexity only when you have the data to prove it adds engagement rather than friction.
Brandfire's sales promotions team has worked with CPG and FMCG brands across Ireland and international markets to design on-pack loyalty mechanics that balance consumer engagement with commercial rigour, from Avonmore Cream's summer on-pack promotion to Aldi's nationwide receipt-upload footfall drive. The approach is always to start with the brand's specific objectives and work backwards to the mechanic, rather than applying a template. For brands considering the wider promotional landscape alongside a loyalty mechanic, our guide to choosing an FMCG promotion agency in Ireland covers what to look for in a partner.
Running a CPG loyalty programme at scale requires a technology platform that can handle high volumes of code validation or receipt processing, manage reward fulfilment across a diverse reward catalogue, power personalised communications across email and mobile, and provide robust analytics.
The temptation to build bespoke is real in FMCG, particularly for brands that have complex product structures or unusual retailer relationships. But the build-versus-buy decision should be made carefully. Custom platforms take longer to deliver, cost more to maintain, and tend to lack the out-of-the-box integrations that modern CRM and data infrastructure demand.
Purpose-built loyalty platforms with FMCG-specific functionality (receipt processing engines, barcode validation, fulfilment integrations, fraud detection) can be deployed faster and at a lower total cost of ownership than most custom builds. They also benefit from ongoing product development driven by other programmes on the same platform.
Whatever technology you use, the platform needs to sit within a clear data architecture. Consumer data collected through the programme should feed your CRM, your CDP, and your analytics tools. It should be governed by a clear privacy policy that explains to consumers exactly what data you are collecting and why. GDPR compliance is non-negotiable, and the consent architecture for a loyalty programme that tracks purchase behaviour needs to be designed carefully from the start.
Brandfire's rewards platform is built to handle the specific demands of FMCG and CPG programmes, including on-pack code validation, receipt scanning, multi-retailer purchase attribution, and real-time reward issuance. It has powered receipt-validation mechanics for Aldi and for SuperValu & Centra, and integrates with the CRM and data tools that enterprise CPG brands already use.
The CPG loyalty programmes that deliver the strongest commercial results share a few common characteristics.
Consumer-centricity comes first. The reward proposition starts with what the target consumer values, not with what is cheapest to offer, and the registration journey gets tested obsessively to remove friction. Personalisation is there from the start, even if the early version is relatively simple.
Trade engagement tends to separate the programmes that last from the ones that quietly fade. The retailer knows about the programme before it launches, and where possible is a partner rather than a bystander, with the data arrangement reflecting that, in the way Nectar360 formalises data-sharing between Sainsbury's and its FMCG suppliers. In-store point-of-sale material drives awareness and registration from the first day of availability.
Measurement is built in, not retrofitted. The analytics infrastructure is in place before the programme goes live, not added after the first disappointing quarterly review, and the team knows exactly what they are tracking and what they will do if those numbers slip.
None of this happens by accident. FMCG loyalty programmes carry a specific set of operational challenges, packaging timelines, fraud management, retailer relationships, high-volume fulfilment, that are easiest to navigate with partners who have dealt with them across multiple deployments before.
A CPG loyalty programme is not a quick win. It requires upfront investment in strategy, technology, and creative, and it takes time for the consumer database to grow to a size where the data assets become genuinely powerful.
But the brands that make that investment consistently are building something that competitors without a direct consumer relationship cannot easily replicate. A database of identified, consented, engaged consumers who have demonstrated preference for your brand is a strategic asset with value well beyond any individual campaign.
The question for CPG marketing leaders is not whether building that asset is worthwhile. The question is where to start, and how to build it in a way that delivers commercial returns at every stage rather than only at the end.
If you are working through that question for your brand, talk to the Brandfire team. We have been designing and delivering CPG and FMCG loyalty programmes in Ireland and internationally since 2012, and we can help you find an approach that fits your category, your trade relationships, and your commercial ambitions.
What is a CPG loyalty program?
A CPG loyalty program is a structured scheme run by a consumer packaged goods brand, rather than the retailer that sells its products, to identify individual shoppers, reward repeat purchase, and build a first-party data asset. Because the brand does not usually control the till, it has to earn that relationship through its own mechanics, most often receipt scanning, on-pack codes, or a data-sharing partnership with a retailer.
Which loyalty mechanic should a CPG brand choose - receipt scanning, on-pack codes, or a retailer data partnership?
Match the mechanic to what you can control and what the reward can justify. On-pack codes suit a brand with a strong, well-designed pack and a reward simple enough to explain in five seconds. Receipt scanning suits a brand that needs richer purchase context (which retailer, basket value) and can tolerate a slightly higher drop-off from the extra upload step. A retailer data partnership needs no consumer action at all, but only works where a retailer is willing to share data commercially, which is a trade negotiation, not a technology decision. Many mature programmes end up combining more than one mechanic rather than picking a single one.
Are there real examples of CPG brands running their own loyalty schemes?
Yes. Beyond the UK's PG Tips Cuppa Club, referenced above, Brandfire has delivered on-pack and receipt-based mechanics for brands including Avonmore Cream, Hunky Dory, Aldi, and SuperValu & Centra, each attributing a purchase back to the brand or retailer running the promotion regardless of which specific till the sale passed through. What they share is a mechanic simple enough that a shopper understands the ask before they've finished unpacking their bag.
What first-party data can a CPG loyalty program realistically collect?
At minimum, registration data (email, basic demographics), purchase data (product, retailer, and purchase date), and engagement data (how the consumer responds to your communications). With the right platform and a longer-running programme, that expands into attitudinal survey data, in-app preference signals, and cohort analysis on what drives repeat purchase versus what predicts a lapsed member. This is the asset that lets a brand personalise media and product decisions without depending on a retailer to share its own data.
What is the biggest risk to a CPG loyalty program's success?
Retailer relationships, more often than technology or budget. Most major grocery retailers run their own loyalty schemes and can be wary of a supplier brand running a competing mechanic inside their stores. Getting trade buy-in before launch, and structuring the mechanic so it complements rather than competes with the retailer's own programme, is usually the difference between a scheme that gets in-store support and one that gets quietly deprioritised at shelf level.
Should a CPG brand build its own loyalty platform or buy one?
Buy, in the large majority of cases. Purpose-built loyalty platforms with FMCG-specific functionality, receipt processing, barcode validation, fulfilment integrations, and fraud detection, deploy faster and cost less over the programme's life than a custom build, and they benefit from product development shared across every other brand on the platform. Custom builds are occasionally justified for brands with unusually complex product structures or retailer relationships, but that should be the exception, not the starting assumption.
We'll help you choose the right mechanic for your category and retailer relationships, and build the technology to run it without friction.
