Hill's Till Slip Competition
Driving sales and growing Hill's opt-in database via WhatsApp
Rewarding pet parents
In early 2026, Hill's Pet Nutrition set out to achieve something simple but powerful: give pet parents another compelling reason to choose Hill's at shelf.
Rather than relying on traditional gift-with-purchase mechanics or couponing, the brand opted for a fully digital, till slip-led WhatsApp competition designed to drive measurable sales uplift while simultaneously growing its first-party database.
Techsys Digital was brought in to design and build the end-to-end solution.

Turning Purchases into Entries
Running from 15 January to 31 March 2026, the campaign invited pet parents to purchase any Hill's product and submit their till slip via WhatsApp for entry into a draw featuring:
Grand Prizes
Top-tier rewards for lucky pet parents
VIP Store Prizes
Outlet prizes tracked at store level
Every valid till slip equals one entry, meaning the more Hill's products purchased, the greater the chance to win. But this wasn't just about prize mechanics, it was about building long-term value.
Smart Technology, Seamless Experience
The competition was powered by Techsys SmartSlip™ technology, enabling real-time invoice validation and robust fraud mitigation. Each submitted till slip was automatically assessed against key criteria:
Invoice uniqueness
Valid Hill's purchase
Purchase date within competition period
Store identification where available
Smooth entry flow
If valid, pet parents received confirmation and were automatically entered into the draw. If unclear or unreadable, the system prompted resubmission with guidance, ensuring a smooth and fair experience.
Store-level tracking
Behind the scenes, the system also allocated entries to specific stores, enabling VIP outlet prize tracking and store-level performance analysis.
Built to Drive Sales — and Data
The primary objective of the campaign was clear: drive sales volume by providing another strong reason to purchase Hill's during the promotional period.
Secondary objectives included:
Specialty store switching
Encourage pet parents to choose pet specialty stores
Competition vs couponing
Test competition-led incentives versus traditional couponing
Grow opt-in database
Expand Hill's first-party opt-in consumer base
To support this, the WhatsApp journey captured high-quality first-party data before or alongside slip submission. All opt-in data was structured for integration into Hill's Snowflake CRM environment.
Intelligent Reminders & Re-Engagement
To maximise repeat purchase, the campaign included:
Four-week reminder
Reminder pushes four weeks after a user's initial entry
