Built for Shopify-first fulfillment teams

Choose the right carton
before the label gets bought.

Cartonify gives merchants a packaging brain between Shopify and their shipping stack. Pull SKUs, fill missing dimensions, recommend the best box or satchel, and push the final package set back into fulfillment — including multi-package orders.

Made for the workflow you already have

Shopify upstream. Cartonify in the middle. Shipping tools downstream.

The architecture is deliberate: orders come from Shopify, packaging intelligence lives in Cartonify, and operational shipping tools receive the final package set. That keeps the control plane clean and avoids using label systems as the source of truth.

Core capabilities

Built for fulfillment teams that need operational answers, not just rate estimates.

Cartonify is about selecting the actual package before label print — especially when dimensions are incomplete, packaging rules vary, and some orders genuinely need more than one carton.

01

SKU sync + data cleanup

Pull variants and SKUs from Shopify, flag missing dimensions or weights, then export and re-import a CSV to clean up the catalogue fast.

02

Rule-aware cartonisation

Account for packaging weight, padding, satchel preference, fragile handling, and merchant-specific carton libraries instead of relying on a one-size-fits-all box list.

03

Multi-package from day one

Support orders that need two or more packages, show item-to-package allocation, and give operators a clean override path before syncing downstream.

04

Downstream connector layer

Write the final package decision back to Shopify first, then propagate it to ShipStation and Shippo so pack/label workflows stay aligned.

05

Exception visibility

See which orders are missing SKU data, which recommendations need review, and which syncs failed — with an audit trail rather than mystery behavior.

06

Embedded merchant UX

Live inside Shopify Admin as a proper embedded app, while still giving your ops team a packaging-focused workspace and a public landing page for install and conversion.

How it works

A clean packaging workflow from SKU sync to label-ready output.

1
Sync catalogues from Shopify

Import product variants, SKUs, and open orders. If dimensional data is patchy, Cartonify highlights exactly what needs filling.

2
Enrich via CSV or in-app edits

Bulk export missing rows, enrich dimensions and weights, then bring them back into a normalized merchant catalogue.

3
Recommend package sets

Generate a best-fit single or multi-package result with alternatives, warnings, and operator override controls.

4
Write back and sync downstream

Save recommendation metadata to Shopify first, then push the final package set into ShipStation or Shippo for shipping execution.

Draft pricing direction

Simple to start, flexible enough to grow with more orders and connectors.

This is placeholder pricing copy for now, but it gives the page a realistic commercial shape for review. We can tighten the actual plan later.
