Why apps fail for most local businesses
App stores, install friction, update costs, and near-zero retention unless you already have massive demand. A hungry customer will open WhatsApp or a browser. They will not hunt for your APK.
The stack that actually works
Mobile-friendly website or catalog + WhatsApp notifications + optional automation for status updates. Add payments when your fulfillment is stable. Keep aggregators if they bring volume — and protect a direct channel for regulars.
When an app might make sense later
High repeat frequency, strong brand, and a reason for loyalty features can justify an app — after web ordering already works. Build the habit on the web first.
Implementation order we recommend
Clear offer on a mobile site → structured order capture → WhatsApp confirmations/updates → inventory guardrails → only then consider heavier products.
