Shopify Partner development services

Custom Shopify app development, proven in production.

When off-the-shelf apps cannot solve how your store actually sells, we build the one that does. Our custom Shopify app development is running in live stores today — including the Farmer Brad Weighted Variant app, built for selling food by weight.

Selling by weight, solved

Built for a working farm store on Shopify

Selling food by weight is awkward in a standard Shopify catalog — a package of beef is never exactly one pound. The Weighted Variant app lets Farmer Brad list products with approximate weights and per-pound pricing, then charges customers for the exact weight of what ships.

Per-pound pricing with approximate package weights on every listing
Orders adjust to the exact weighed amount before payment is captured
Works alongside regular fixed-weight products in the same store
Runs in the Shopify admin — no spreadsheets or manual refunds

What we build

Custom apps for the way your store sells.

Every custom app we build runs inside your Shopify admin and works on any plan level — and with Shopify POS added to any plan if you also sell in person.

Weighted and unit-based selling

Sell by the pound, ounce, or any unit — approximate weights at listing time, exact charges when the order ships.

Workflow and automation apps

Automate the repetitive parts of your operation — order routing, approvals, tagging, and notifications that fit how you work.

Inventory and fulfillment tools

Track stock across locations, sync with suppliers, and keep fulfillment moving without spreadsheets.

Reporting and integrations

Custom dashboards and connections to the other tools your business runs on, built into the Shopify admin.
