Checkout rates that match how you actually ship

Flat rates and Shopify defaults train buyers on the wrong promise. ShipManta Shipping Rates profiles price the cart the way the warehouse builds the box.

The problem

Checkout offers cheap ground. The cart is live food that always ships express. Margin disappears before the label exists.

What stores report

Alongside date-picker threads, merchants want custom methods with honest pricing — zones, product groups, and surcharges that match operations. When checkout lies, the warehouse either absorbs the loss or changes the method after payment.

How ShipManta solves it

Shipping Rates profiles define zones, groups, tiers, combination rules, and triggers. You clone a live profile, test a cart through the real engine, then activate. Diagnostics answer “why did this cart get Live Food Flat Rate?” from the same code checkout uses.
