TL;DR

CheckoutSmart and Brand Allies are both UK platforms that generate verified product reviews on grocery retailer websites using real shoppers. CheckoutSmart, founded in 2012, is the established player with automated “Always On” review monitoring, proprietary benchmarking data, and a client list of large manufacturers like Heineken and Mars. Brand Allies, launched in 2024 and powered by Redwigwam’s 250,000-strong shopper community, offers pay-per-verified-review pricing alongside in-store compliance audits and discreet product recalls. Your choice depends on budget model, brand size, and whether you need services beyond reviews.

Why This Comparison Matters

Eighty-five percent of grocery products listed on UK retailer websites need new, up-to-date reviews, according to CheckoutSmart’s own quarterly analysis. The average grocery review rate sits between 0.1% and 0.3%, compared to 2% to 5% on Amazon. That gap is why platforms like CheckoutSmart and Brand Allies exist: they recruit real shoppers to buy products, try them, and post genuine reviews on retailer PDPs.

If you manage the digital shelf for a UK FMCG brand, you have probably encountered both names. This guide breaks down what each platform actually does, where they overlap, and which one fits different brand profiles.

Quick Comparison Table

What Is CheckoutSmart?

CheckoutSmart is a London-based shopper marketing and review generation platform founded in 2012 by Paul Lees and Chris Howarth, both with backgrounds at Procter & Gamble, Mars, and Heinz. The company has raised $2.4M in funding, employs around 16 people, and works with over 100 FMCG partners in the UK. It also acquired German cashback app Scondoo to expand into Europe.

The platform runs three solutions:

SmartReputation (Always On): This is CheckoutSmart’s flagship product. It continuously monitors SKU-level review health across all major UK grocery retailers. When a product drops below their defined standards, the system automatically triggers new review generation. Those standards are specific: at least 30 reviews per SKU per retailer, the top three reviews no older than six months, and a star rating within 1.5 stars of the category average.

SmartActivation: Cashback campaigns designed to drive trial and boost rate of sale. Shoppers receive instant cashback for purchasing specific products, which has been a core offering since 2014.

SmartInsights: An AI-powered analytics tool built for FMCG teams, designed to understand category hierarchies and real shopper language rather than generic text patterns. CheckoutSmart also runs an AI Consumer Panel that researches how AI-powered product discovery is changing shopper behaviour.

Their published client list includes Heineken, Arla, Lactalis, Müller, Mars, McCormick, Carlsberg Britvic, General Mills, Dr Oetker, and Tropicana. In terms of results, Kellogg’s reported a 32% ongoing increase in sales from new reviews delivered by CheckoutSmart, and the platform generally claims a 25% to 35% uplift in online sales once a minimum of 30 reviews are in place. Their stated ROI at gross margin level is 6x to 12x, meaning £6 to £12 back for every £1 spent.

CheckoutSmart has also built significant thought leadership. Their quarterly Top 150 rankings analyse how the UK’s largest FMCG manufacturers perform on online shopper reputation. Combined with original research (a 3,710-shopper survey with Profitero on review influence) and the AI Consumer Panel, they often become the first name a brand team encounters when researching the review gap.

What Is Brand Allies?

Brand Allies is a managed-service shopper advocacy platform launched in 2024 as the retail and FMCG sub-brand of Redwigwam, a staffing marketplace with over a decade of operating history and Maven/NPIF funding. It is registered as RWW Group Limited, based in Liverpool.

Brand Allies operates three service lines:

Online Product Reviews: Real shoppers from Redwigwam’s 250,000-strong UK community purchase products with their own money and post verified reviews on retailer websites. Coverage includes Tesco, Sainsbury’s, Morrisons, Waitrose, Ocado, Boots, Iceland, Holland & Barrett, Amazon, and TikTok Shop.

In-Store Activations: Field audits covering promo compliance, POS visibility checks, and distribution monitoring. This builds on technology piloted with Kellogg’s through Redwigwam’s “24/7 Availability” programme, where Kellogg’s Head of Field Sales publicly confirmed “a successful pilot that delivered a great ROI.”

Discreet Product Recalls: Shoppers physically remove faulty products from shelves without triggering a public FSA alert. This is closer to a market withdrawal than a formal recall and is a service no other UK review platform currently offers.

Homepage client logos include Coca-Cola, Strong Roots, Little Moons, Bol Foods, and Jordans. The pricing model is pay-per-verified-review with no SaaS lock-in or enterprise minimum spend.

Key Differences Between CheckoutSmart and Brand Allies

Pricing Model

This is probably the sharpest dividing line when comparing CheckoutSmart vs Brand Allies. CheckoutSmart operates as a managed service with bespoke pricing. There are no public price lists, and the engagement model is typically oriented toward larger manufacturers with dedicated ecommerce budgets. Brand Allies charges per verified review, removing upfront budget risk.

For a deeper breakdown of what review generation typically costs, see this review pricing guide.

The practical difference: if your brand has a consistent annual budget for digital shelf management, CheckoutSmart’s Always On model makes sense as a standing investment. If you operate in quarterly NPD cycles or need to prove ROI before committing to an annual contract, pay-per-review lets you start smaller.

Service Scope

CheckoutSmart’s three pillars are reviews, cashback activations, and AI-powered insights. Brand Allies’ three pillars are reviews, in-store compliance audits, and discreet product recalls.

No other UK provider currently bundles reviews, field audits, and recall capability under a single contract. For brand teams that struggle with in-store compliance alongside review gaps, consolidating under one supplier reduces vendor management overhead.

CheckoutSmart’s strength lies in the other direction: its analytics and benchmarking data. The SmartInsights AI tool and quarterly Top 150 reports give brand teams ammunition for internal presentations and retailer negotiations. Brand Allies doesn’t yet publish equivalent data.

Ideal Client Profile

CheckoutSmart’s client roster is dominated by large multinational FMCG manufacturers. Their engagement model, managed service pricing, and broad SKU monitoring are built for companies that list hundreds of products across every major retailer.

Brand Allies works with both enterprise names (Coca-Cola) and challenger brands (Strong Roots, Little Moons). The pay-per-review model and absence of minimum spend thresholds make it more accessible to brands that are earlier in their retail journey or working with tighter budgets. If you’re a challenger brand figuring out retail execution options, this flexibility matters.

Activation Speed

CheckoutSmart typically runs a pilot over 4 to 8 weeks. Brand Allies claims activation in hours rather than weeks, because Redwigwam’s workforce is already ID-verified and geo-indexed across the UK. The speed difference is most relevant for NPD launches or seasonal products where review coverage needs to appear quickly.

Retailer Coverage

Both platforms cover the core UK grocery retailers: Tesco, Sainsbury’s, Morrisons, Waitrose, Ocado, Boots, and Iceland. The differences sit at the edges. CheckoutSmart includes Asda and Superdrug. Brand Allies includes Holland & Barrett, Amazon, and TikTok Shop.

For health and beauty brands or DTC-to-retail brands expanding into newer channels, Brand Allies’ TikTok Shop and Holland & Barrett coverage is a meaningful differentiator. For brands selling through Asda or Superdrug, CheckoutSmart has the edge.

Thought Leadership and Data

CheckoutSmart wins this category decisively. Their quarterly Top 150 rankings, the Profitero research partnership, published case studies, and AI Consumer Panel create an information ecosystem that FMCG teams encounter long before they start comparing vendors. That research found that the number of reviews is the single biggest influence on retailer search ranking, a correlation confirmed across five of the top six UK supermarkets.

Brand Allies is building content but is still early. Its parent Redwigwam has press coverage and a longer public track record, but Brand Allies itself has fewer than two years of published material.

How Both Platforms Generate Reviews

The underlying mechanism is essentially the same for both platforms. A real shopper purchases the product with their own money, either in-store or online. They upload proof of purchase (receipt or order confirmation) to the platform. They receive a cashback payment. They are then invited, not required, to leave a review on the retailer’s website.

This distinction matters. Neither platform guarantees that reviews will be positive, and neither platform scripts or pre-approves review content. The shopper writes what they think. This keeps the process on the right side of authenticity, but it also means some reviews will be three stars, not five.

Both platforms describe their reviews as 100% authentic and verified. For a fuller explanation of what verified reviews mean and why that label matters, see our glossary entry.

Review Standards: The 30-Review Threshold

CheckoutSmart has published a clear benchmark: 30 reviews per SKU per retailer, with the top three reviews under six months old and the star rating within 1.5 stars of the category average. When a product drops below any of these thresholds, their Always On system triggers new review generation automatically.

This aligns with broader industry data. Research consistently shows that the first 30 reviews represent a credibility threshold. Below that number, shoppers are significantly less likely to trust the product page. Above it, the star rating itself becomes the dominant conversion factor. CheckoutSmart’s own shopper survey of 3,710 respondents ranked the top review elements: star rating first, number of reviews second, recency a close third.

Brand Allies does not publish a formal review standard, but operates in the same reality. Both platforms exist because grocery PDPs are desperately under-reviewed.

See how review pricing works across different service models.

Review Compliance in the UK

Both platforms operate in a regulatory environment that tightened significantly in April 2025. The Digital Markets, Competition and Consumers Act (DMCC Act) 2024, which came into force that month, gives the CMA power to impose fines of up to 10% of global annual turnover for serious consumer law breaches, without needing a court order. That is a fundamental shift in the risk profile of non-compliance.

The ASA’s guidance on incentivised reviews draws a specific line. Providing incentives to encourage people to leave genuine, unbiased reviews is potentially acceptable. Directly incentivising consumers to leave positive reviews is problematic. Both CheckoutSmart and Brand Allies sit on the acceptable side of this line by design: shoppers receive cashback for purchasing, and leaving a review is optional. There is no requirement for the review to be positive.

That said, both platforms operate in a grey zone. Shoppers who receive cashback may feel an implicit pressure to be generous, even if no explicit instruction exists. Retailer moderation teams can and do reject reviews they suspect are incentivised. This is not a flaw unique to either platform. It is the structural challenge of any review generation service in the UK.

For brand teams evaluating either platform, the key compliance questions are the same. Are reviews disclosed as incentivised where required? Is there any screening or filtering of negative reviews? Can you demonstrate to the retailer (and to the CMA if needed) that the process is transparent?

Which Platform Suits Your Brand?

Choose CheckoutSmart if:

• You manage a large SKU portfolio across all major UK retailers and need automated, always-on monitoring.
• You want proprietary benchmarking data (Top 150 rankings, AI Consumer Panel) to support internal and retailer-facing presentations.
• Your budget supports a managed service engagement without per-unit pricing.
• You need cashback activation campaigns alongside review generation.
• You are expanding into European markets (Germany via Scondoo).
• Published case studies and quantified ROI (the Kellogg’s 32% uplift, the 6x to 12x gross margin return) are important for your business case.

Choose Brand Allies if:

• You want pay-per-verified-review pricing with no SaaS commitment or minimum spend.
• You need in-store compliance audits, POS checks, or discreet product recalls alongside reviews, under one contract.
• You are a challenger brand or mid-size manufacturer without the budget for a standing managed service.
• You need coverage on Holland & Barrett, Amazon, or TikTok Shop.
• Speed matters: you need reviews live in days rather than weeks for an NPD launch or seasonal push.
• You want access to a 250,000-strong UK shopper community that is already ID-verified and geo-indexed.

Can you use both? Yes. Some brands use CheckoutSmart for always-on review maintenance across their core range while running targeted Brand Allies campaigns for NPD launches or specific retailer gaps. The two platforms are not mutually exclusive.

Frequently Asked Questions

Are incentivised reviews legal in the UK?

Yes, provided the incentive encourages an honest review rather than a specifically positive one. The ASA’s CAP Code and the DMCC Act 2024 prohibit fake reviews and require disclosure of material connections. Both CheckoutSmart and Brand Allies design their processes so that reviews are optional and unscripted. Read more about UK review compliance rules.

How many reviews does my product need per retailer?

The widely cited threshold is 30 reviews per SKU per retailer. Below that, shoppers are less likely to trust the product listing. CheckoutSmart uses this as one of three Always On triggers. Above 30, the star rating and recency of reviews become more influential than raw count.

Do reviews stay up permanently?

That depends on the retailer. Most UK grocery retailers display reviews indefinitely, but recency matters. CheckoutSmart’s research shows that shoppers rank review freshness as the third most important factor after star rating and volume. A product with 50 reviews that are all two years old will underperform one with 30 recent reviews.

What happens if a retailer rejects a review?

Both platforms face this. Retailer moderation teams may reject reviews they suspect are incentivised, duplicated, or insufficiently detailed. Neither platform can guarantee a 100% acceptance rate. This is why review velocity (a steady flow of submissions over time) matters more than a single large batch.

What is CheckoutSmart’s “Always On” model?

It is a continuous monitoring service. CheckoutSmart tracks every SKU in your portfolio across every covered retailer. When a product falls below their three benchmarks (30 reviews, top three under six months, rating within 1.5 stars of average), the system automatically generates new reviews. You do not need to brief individual campaigns.

Does Brand Allies offer anything beyond reviews?

Yes. Brand Allies operates three service lines: online product reviews, in-store compliance audits, and discreet product recalls. No other UK review platform bundles all three under a single contract.

Which platform has better retailer coverage?

Both cover the core UK grocery retailers. CheckoutSmart adds Asda and Superdrug. Brand Allies adds Holland & Barrett, Amazon, and TikTok Shop. Your choice depends on where your products are listed.

How much do these services cost?

CheckoutSmart uses bespoke managed-service pricing, which is not publicly listed. Brand Allies charges per verified review with no minimum spend. For a broader look at the market, see this pricing comparison guide.
