Asking the customer to reorder instead of buying them back
Pet food, supplements, cosmetics, cleaning products — the repeat purchase is built in, yet most stores pay to reacquire the same customer through ads.

Situation
Consumable categories have a repeat purchase built into them.
Most stores still pay to reacquire the same customer through ads instead of simply asking them to reorder.
Approach
The system connects to ikas or Shopify, reads order history and infers each product’s consumption cycle.
Messages are timed to land shortly before the customer runs out, with a direct path back to the basket. No app to install, no e-mail to ignore.
The engineering constraint is the interesting part: WhatsApp Business messaging is template-gated and rate-limited, so templates, opt-out handling and scheduling all have to be modelled properly — get it wrong and you lose the channel, not just the campaign.
Result
Repeat revenue comes back through a reminder rather than through paid reacquisition.
Because the channel rules are modelled, the system runs continuously rather than per campaign.
