The Problem

CoD stores receive daily Excel reports from logistics companies listing delivery outcomes. Staff were manually opening each file, finding each order in Shopify, and updating statuses one by one — hundreds of updates a day, with constant errors and customer complaints from delayed status changes.

Our Approach

The core problem was reliable matching: logistics spreadsheets come in inconsistent formats, tracking IDs don't always align cleanly with Shopify order data, and a duplicate update can corrupt fulfillment records. We had to solve all of that before touching a single order.

What We Built

Built a Rails automation system with a flexible Excel/CSV parser that handles column inconsistencies across different logistics providers. An order matching engine resolves tracking IDs to Shopify orders, then bulk-updates fulfillment and payment statuses via the Shopify Admin API. Duplicate prevention logic prevents double-processing. Admin dashboard for upload, monitoring, and reviewing failed syncs.
