Build

POS export -> customer segmentation -> WhatsApp loyalty -> review request -> win-back campaign

The store had buyers, but no repeat-purchase memory

Customer phone numbers existed in POS exports, but the team did not know who bought what, who had not returned, or who should receive which offer. Broadcasts were generic and discount-heavy, causing poor response and opt-outs.

Segmented WhatsApp journeys based on purchase history

We cleaned customer data, segmented buyers by category and recency, and built WhatsApp journeys for review requests, loyalty offers, product replenishment, birthdays, and inactive-customer win-back. Messages were based on purchase behavior instead of blanket discount blasts.
