Offline‑first PWAs are essential for street sellers and market stalls. This 2026 guide shows how to implement resilient checkout, caching and on‑device promotions.

Hook — Sell Even When the Grid Doesn't

In 2026, the difference between a missed sale and a loyal customer is often network resilience. Offline‑first PWAs let agora sellers collect payments, record inventory and deliver promotions without full connectivity.

Key features for seller PWAs

Offline cart persistence and queued sync.
On‑device coupons and cached promotions.
Compact asset footprints to reduce cold start times.

Architecture notes

Use a cache‑first service worker strategy for product assets, and an incremental sync for orders to avoid conflicts. Tie local ads to on‑device inference for personalized upsells with privacy preserved.
