F12 LabsWe build the Shopify features that aren't in the box.
F12 Labs makes Shopify apps and custom Shopify solutions: pricing and discounts on Shopify Functions, native bundles, cart tools, and integrations with the systems you already run.
Our apps
Each one does one job well, runs on Shopify's own features and starts with a free plan. Install them from the Shopify App Store.
Volume pricing, buy X get Y, free gifts and shipping discounts on Shopify Functions.
- Tiered and volume pricing
- Free gifts added to the cart
- Offer blocks for your theme
Native Shopify bundles from the exact variants you choose, priced from their products.
- Stock tracked from components
- Percentage-off or fixed bundle pricing
- REST API for ERP and PIM
The same cart on every device for signed-in customers, and a cart builder for your team.
- Carts saved to the customer record
- Guest items kept at sign-in
- Cart Helper in your admin
More on the way
We're building the next one now. If your store needs something Shopify doesn't do yet, tell us.
What we build
The same work that goes into our apps, for your store: we know where Shopify ends and how to extend it cleanly.
Apps for the Shopify App Store
Public apps from first sketch to App Store review: embedded admin, billing through Shopify, privacy webhooks and listing.
Like Discountly, Bundles Pro and CartSync ProDiscount and checkout logic
Shopify Functions for pricing rules the built-in discounts can't express, running inside Shopify's checkout.
See DiscountlyStorefront features that fit your theme
Theme app blocks and embeds that merchants place in the theme editor, with no theme code to edit or maintain.
See CartSync Pro and Bundles ProTools for your team, in the admin
Embedded pages and admin blocks that put the right information on the product, order or customer page staff already use.
See Cart Helper in CartSync ProIntegrations with your other systems
Connect Shopify to an ERP, PIM or warehouse through the Admin API and webhooks, or give those systems an API of their own.
See the REST API in Bundles ProCustom apps for one store
When no public app does what your store needs, a private app built for your workflow and nobody else's.

How we work
Three rules behind every app and every custom build.
Native first
We build on Shopify's own features, like native bundles, Functions and metafields, so checkout, orders and reports keep working the way Shopify intends.
Your data stays in Shopify
Store data lives in Shopify wherever it can. Our servers keep only what an app can't run without, and our privacy policies say exactly what that is.
Plain about limits
Every app page says what the app doesn't do as clearly as what it does, so you can decide before you install.
