Shopify: Mass Uploads

Editing a large catalog one product at a time is slow, and one bad CSV can undo the work.

Big Catalogs Without the Busywork

Your catalog has grown past what anyone can update by hand. New products wait in a spreadsheet, prices fall out of date, and variants end up with the wrong images.

We handle mass uploads, updates and data management using Shopify’s bulk operations API, CSV imports and custom scripts. That keeps your catalog accurate and up to date, even with thousands of SKUs.

How a Bulk Upload Runs

1

Map Fields

We match your ERP, product system or spreadsheet export to Shopify’s format, then write the scripts that convert it.

2

Prepare Media

Images get compressed and resized, then matched to the right products and variants, with alt text where you want it.

3

Load Catalog

Products, variants, images and metafields go in through Shopify’s bulk operations API, which is built for large volumes.

4

Schedule Imports

If your catalog changes often, we set up a recurring import that pulls, converts and pushes updates on a schedule.

Why Choose System Strats

We’ve built Shopify operations for a range of brands. Catalog data feeds everything else in the store, so we treat each upload as an operations job as well as a data task.
