Optimize every box.
Reduce every cost.

Ship-ify intelligently groups order items into your available boxes so you ship fewer packages and pay less for shipping.

How Ship-ify Works

You control the payload. We optimize the packing.

1

Define & Dispatch

Send your order items with dimensions and available box inventory via a single POST request to our endpoint.

You define the payload—items, boxes, constraints—for every request. Full control, no surprises.

2

Intelligent 3D Grouping

The shipify-ultra algorithm instantly calculates the mathematical best-fit, virtually test-packing items to maximize density.

Our engine evaluates rotations, placement strategies, and box combinations to minimize wasted space.

3

Execute & Save

Receive optimized packing instructions and utilization metrics in <50ms, allowing you to print labels and reduce dimensional weight costs immediately.

JSON response includes box assignments, exact item positions, and efficiency stats ready for your warehouse or label system.

Algorithmic Box Selection & Density Optimization

Reduce shipments by maximizing every cubic inch.

Example 1: Volume Optimization

Without Ship-ify

3 separate boxes for a 5-item order
Boxes half-empty, paying for air
Higher DIM weight = higher shipping cost
3 boxes, 4,200 in³ billed
Excess packaging and dimensional charges

With Ship-ify

Powered by Shipify-Ultra algorithm
Same 5 items fit in 2 optimized boxes
33% fewer packages to ship
Lower DIM weight, lower cost
2 boxes, 2,800 in³ billed
33% reduction in billed volume
92%
Volumetric Efficiency
Reduced by 4 lbs
DIM Weight Reduced

Example 2: Weight Threshold Optimization

Without Ship-ify

1 oversized box for an 8-item order
58 lbs triggers UPS Additional Handling fee
Paying for empty space inside the box
1 box, 5,400 in³ billed + $28.50 surcharge
Overweight penalty and wasted dimensional volume

With Ship-ify

Powered by Shipify-Ultra algorithm
Same 8 items split into 2 right-sized boxes
29 lbs each — under the 50 lb threshold
33% less billed volume, no surcharges
2 boxes, 3,600 in³ billed, $0 surcharges
33% less volume + $28.50 surcharge avoided
88%
Volumetric Efficiency
Reduced by 6 lbs
DIM Weight Reduced

Examples based on typical multi-item orders. Packages over 50 lbs incur carrier surcharges (~$28.50 with UPS as of 2025). Actual savings vary by order composition, box inventory, and carrier.

Who Ship-ify is for

  • E-commerce teams shipping multi-item orders where box selection materially affects cost
  • Developers who want a clean, deterministic API instead of building and maintaining packing logic
  • Operations teams tired of packing decisions being made by guesswork on the warehouse floor
  • Businesses with five or more box sizes that suspect they're over-boxing orders
  • Teams spending enough on shipping that a 10–20% reduction would more than cover the subscription

Who Ship-ify is probably not for

  • Single-SKU businesses where every order ships in the same box
  • Companies using a 3PL that fully controls packing and box selection
  • Very low-volume shippers (the free tier is available if you want to experiment)
  • Teams without the ability to integrate an API

What Ship-ify Does Not Do

We do one thing well and integrate cleanly with your existing stack

Does not buy or print shipping labels

Does not negotiate carrier rates

Does not replace your WMS or OMS

Does not manage carrier accounts

Ship-ify is a pre-rating optimization layer. Run it before you rate and label, and keep using your existing systems.

Everything You Need to Optimize Shipping

Powerful features to reduce shipping costs and improve efficiency

8 Packing Algorithms

From first-fit to our proprietary shipify-ultra, choose the perfect algorithm for your use case.

Custom Box Sets

Save and reuse box configurations. Includes official carrier templates from USPS, Canada Post, and more.

Usage Analytics

Track API usage, monitor costs, and get insights into your shipping optimization.

3D Visualization

See exactly how items are packed with interactive 3D previews.

Batch Processing

Process up to 50 orders at once with our high-performance batch API.

Detailed Error Diagnostics

When requests fail, get actionable suggestions for fixing malformed input—not just error codes.

Simple, Transparent Pricing

Start free and scale as you grow. No hidden fees.

Most businesses save 20-40% per shipment using multi-box optimization & intelligent packing.

Why we charge per item, not per API call: Batching multiple orders into a single API call is more efficient for everyone. Charging per item optimized aligns with our CPU costs and encourages you to batch orders for maximum efficiency.
