Pricing · Packing Engine

Pay for the box you actually need.

MaxFill prices every shipment from the packing engine up. It computes the most space-efficient box for each order and validates it against carrier rules, so you only ever pay real, optimized shipping cost, at competitive rates.

01

Analyze items

Reads the length, width, height, and weight of every product in the order.

02

Optimize layout

Finds the most space-efficient arrangement of items to minimize wasted volume.

03

Size the box

Calculates the exact box dimensions needed for the shipping container.

04

Validate rules

Checks carrier limits for maximum dimensions, girth, and volume.

05

Return box + rate

Outputs final box specs, packing details, and the optimized shipping rate.

[ Why it matters ]

Efficient packing is lower cost.

01

Cost savings

Smaller boxes mean lower shipping costs. The engine never bills you for shipping air.

02

Carrier compliance

Packages that meet size and dimension rules avoid surcharges and delivery delays.

03

Customer satisfaction

Properly packed items arrive safely and on time, every time.

04

Operational efficiency

Automated packing decisions reduce manual work and human error.

[ What determines your rate ]

From box specs to a real carrier rate.

Once the engine sizes the optimal box, MaxFill prices it against your carrier rate tables, so the number you see is the number it actually costs to ship.

[ FAQ ]

Pricing, answered.

The packing engine analyzes your items, finds the most space-efficient arrangement, and calculates the optimal box. That box's dimensions and weight are then priced against your carrier rate tables, so the rate reflects the real, optimized cost to ship.

The engine packs items into a single box when it can, and splits them across multiple boxes when necessary, pricing each one so the overall shipment stays optimized.

Yes. Every package is validated against carrier requirements for maximum dimensions, girth, and volume, so you avoid surcharges and delivery delays.

Analyzing, optimizing, sizing, validating, and returning the box specs and rate all happen automatically in under a second.

Stop paying to ship air.

Connect your store and let the packing engine price every shipment at its real, optimized cost.
