ServicesShipping & freight integrations

Shipping logic,
matched to operations

Flat rates break the moment products get heavy, oversized, or regulated. We build carrier integrations and rate logic that quote what fulfilment actually costs — including freight and LTL.

What this covers

Freight and LTL workflows

Large-item and palletized shipping quoted and booked correctly — the workflows most Shopify stacks ignore.

Carrier and rate integrations

Live rates from the carriers you actually use, with fallbacks that never show a customer an error.

Dimensional and zone logic

Weight, dimensions, zones, and product classes driving rates — encoded once, tested, and maintainable.

Split and multi-origin shipments

Multiple warehouses, drop-ship vendors, and partial fulfilment modeled without spreadsheet glue.

You are in the right place if

You sell furniture, equipment, or anything a parcel network refuses
Checkout shows shipping prices that regularly lose money or lose orders
Your carrier or 3PL integration relies on manual re-entry
Delivery promises differ by product, region, or stock location

Work like this runs as a scoped $10k+ engagement: blueprint first, then build, then launch QA — with a named technical owner and no silent outsourcing of the thinking.
