5 Things to Consider When Planning Your Next Sales Promotion

Sales promotions are among the most effective revenue-boosting tools a brand has, giving customers a compelling reason to choose one product over another at the exact moment they're deciding. But a promotion that works well on paper can go wrong in five distinct ways, and each one shows up after launch rather than before it. Getting them right up front is what separates a campaign that delivers from one that quietly loses money or draws regulatory attention.

This guide breaks down the five areas worth locking down before a brief goes to sign-off: the technology behind the mechanic, the budget model, risk protection, reward selection, and legal compliance in Ireland and the UK.

The five areas at a glance

Technology	Which mechanic and platform fit your customer base?	Entry experience, fraud exposure, lead times	Receipt validation vs. code-on-pack
Budget	Fixed cost or per-redemption?	Budget certainty vs. exposure to over-performance	Fixed fee promotion guide
Risk protection	Fixed fee, prize indemnity insurance, or both?	Who absorbs the cost of an unexpected outcome	Fixed fee promotion guide
Reward selection	Is the reward proportional and relevant?	Participation rate, perceived value, brand fit	Choosing rewards for a sales promotion
Legal compliance	Does the mechanic trigger a permit or licence?	Fines, forced campaign changes, reputational risk	Gaming and Lotteries (Amendment) Act 2019 / Gambling Act 2005

1. Technology

The technology behind a promotion shapes the entire customer experience, and the right choice depends on the mechanic, not brand preference. On-pack promotions with unique codes need careful planning around print lead times and stock rotation. Receipt and image-recognition technology lets customers photograph a receipt and upload it through a promotional website or text message, which suits high-volume grocery and retail mechanics where proof of purchase matters more than a printed code.

The differences show up clearly across Brandfire's own campaigns. Aldi's Electric Picnic promotion ran a receipt-upload mechanic across 160-plus stores nationwide, where the platform had to hold up under national footfall. Topline's Big Paint Sale went a step further, pairing AI-assisted receipt validation with a skill-based judging engine so winners were assessed on entry quality rather than a random draw. Hunky Dory's Movie Night promotion took the opposite route: an on-pack code mechanic with instant digital reward delivery, so every valid entrant received their reward immediately rather than waiting on a draw.

Platform choice (social media, SMS, WhatsApp, or a dedicated web app) should follow the same logic. ILAC Rewards built a receipt-based mobile app because footfall and repeat engagement across 60-plus shopping centre stores needed an always-on channel, not a one-off campaign microsite. A promotion aimed at occasional purchasers usually doesn't need that level of infrastructure; one aimed at driving habitual, repeat behaviour often does.

2. Budget

Budget structure determines what kind of promotion is realistic to run. A competition with a defined number of prizes has a fixed cost regardless of how many people enter: ten prizes cost the same whether 500 or 50,000 customers take part. A per-customer reward, such as a discount, gift-with-purchase, or cashback offered to everyone who qualifies, scales directly with redemption, and can exceed budget if the promotion performs better than forecast.

Most campaigns discover at this point that they've underestimated one of four cost components: technology, prizes, fulfilment, and management. Avonmore Cream's summer on-pack promotion is a useful reference point. It was built on a fixed fee structure from the outset, wrapping all four components into a single number regardless of how many of the thousands of available prizes were claimed. Our fixed fee promotion guide covers how those four components are priced and where campaigns typically run into unplanned costs.

3. Risk protection

A fixed fee and prize indemnity insurance both protect against financial exposure, but they solve different problems, and brands regularly confuse the two. A fixed fee is a pricing model. The promotions partner absorbs the cost of higher-than-forecast redemption in exchange for one agreed number, which is why it suits high-volume mechanics like receipt uploads or on-pack codes, where participation is genuinely hard to predict.

Prize indemnity insurance is a different instrument. It covers a specific, low-probability, high-value prize rather than general redemption risk, such as a "match the jackpot number" mechanic or a single embedded winning code. Premiums typically run between 3% and 15% of the total prize value, based on the odds of a payout. Most standard promotions need one protection or the other, not both. Our fixed fee promotion guide sets out how to tell which applies to a given mechanic before it's built into the brief.

4. Picking the right reward

The reward has to be proportional to the product value and the effort a customer puts in, and it has to match the target audience. A reward pitched at the wrong demographic, or one that feels disproportionate to what's being asked of the customer, suppresses participation no matter how well the mechanic is built.

Glenisk's partnership with Disney Pixar's Elemental is a clear example of matching the reward to the audience. A children's organic yogurt brand tied its on-pack promotion to a family film, giving the reward direct relevance to the household actually buying the product, reinforced with in-store displays and an experiential screening event rather than a generic voucher. Instantor Rewards shows the same principle applied to a very different audience. Built for Sanbra Fyffe's plumbing trade network, a tiered rewards structure gives trade customers a reason to keep engaging over the long term, rather than a one-off prize that loses relevance after a single redemption.

The "everyone is a winner" approach works well when the reward can be kept modest and the goal is broad participation rather than headline prize value. Every qualifying customer receives something, rather than competing for a few prizes. Hunky Dory's instant movie download for every valid code is a good example of this mechanic done well.

5. Legal compliance

Legal requirements differ sharply between Ireland and the UK, and a promotion running in both markets needs to satisfy both regimes rather than picking one.

In Ireland, the Gaming and Lotteries (Amendment) Act 2019 is the relevant law whenever a promotion both requires a purchase and selects winners at random. A promotional lottery with a total prize fund up to 2,500 euros needs no permit. Between 2,500 and 5,000 euros, a local Garda Superintendent's permit is needed, and the application window opens 60 days out from launch, not the week before. Above that threshold, a District Court licence is needed. Terms and conditions compliant with the Advertising Standards Authority for Ireland's (ASAI) Code are required regardless of prize value.

In the UK, the relevant framework is the Gambling Act 2005, which defines a lottery by whether entrants must pay to take part. Free prize draws and genuinely skill-based competitions (where the skill element is significant enough to deter a meaningful proportion of entrants, or to stop a meaningful proportion of them from winning) fall outside that definition and need no licence. That doesn't remove every obligation. The UK Code of Non-broadcast Advertising and Direct & Promotional Marketing, known as the CAP Code, still requires a clear "no purchase necessary" statement. It also requires a genuinely free entry route whenever a promotion encourages a purchase without strictly requiring one.

Hunky Dory's on-pack promotion is a useful reference here too: lottery licensing guidance was built into the campaign design from the outset, rather than checked as an afterthought once the mechanic was finalised. That ordering matters more than which market a brand is launching in.

Getting the plan right before the brief goes out

None of these five areas work in isolation. The reward choice affects the budget model. The budget model affects which risk protection makes sense. The mechanic affects both the technology and the legal position. Locking down all five before a brief is finalised is what turns a promotion from a campaign with unknown exposure into one with a clear, defensible plan finance and legal can both sign off on.

Frequently Asked Questions

What is the biggest planning mistake brands make with a sales promotion?

Locking in the reward and mechanic before checking the budget model and legal position. A promotion that looks compelling on a whiteboard can carry open-ended redemption risk or trip a lottery licensing threshold - both are far cheaper to catch at the planning stage than after launch.

Is a fixed fee the same as promotional risk insurance?

No. A fixed fee is a pricing model: one agreed cost that absorbs redemption risk from over-performance. Prize indemnity insurance is a separate product that covers a specific low-probability, high-value prize. Most promotions need one or the other, not both - see our fixed fee promotion guide for the full breakdown.

Do I need a lottery licence for a sales promotion in Ireland?

Only in specific circumstances. Under the Gaming and Lotteries (Amendment) Act 2019, a promotional lottery tied to a purchase with a total prize fund up to 2,500 euros needs no permit. Between 2,500 and 5,000 euros requires a Garda Superintendent's permit, applied for at least 60 days before launch. Above that, a District Court licence is required.

Does the same legal test apply in the UK?

No, and this catches out brands running the same mechanic in both markets. Ireland's exemption depends on prize value; the UK's depends on whether entry costs anything at all. A free entry route or a genuine skill test keeps a UK promotion outside the Gambling Act 2005, but the CAP Code still expects a visible no-purchase-necessary line wherever the promotion nudges people toward buying.

How do I decide between a competition mechanic and a per-customer reward?

Ask which risk you'd rather carry. A capped-prize competition gives budget certainty by design, because the cost is set before a single entry arrives. A per-customer reward gives every qualifying customer a guaranteed pay-off, which usually drives stronger participation, but it hands the redemption risk to the brand unless it's priced on a fixed fee basis. Match the choice to how much budget certainty this campaign needs.
