Shirtology — Shopify multi-store ops

The problem we walked into.

Running several Shopify stores from one back office means making the same catalogue change three times over. At ten thousand products, a sync that fails halfway leaves the stores less consistent than before it started — so the team stopped trusting it and went back to doing it by hand.

How we framed it.

A sync that resumes exactly where it stopped instead of starting over, so a dropped connection costs seconds rather than an afternoon. Invoices generate close to the customer rather than queueing behind everything else.

What we shipped.

One dashboard for every store: catalogue sync at ten-thousand-product scale that survives interruption, wholesale customer tagging, and an invoice pipeline that renders quickly under load.

• Catalogue sync across stores that resumes after an interruption rather than restarting
• One dashboard for several Shopify stores at once
• Wholesale customer tagging and pricing
• Fast PDF invoice generation that holds up under load
• A test suite covering scale and security before anything ships
