How to Implement This with GTBuy

1. 1. Consolidate Your Parcel

   Use GTBuy's warehouse service to combine multiple items into one shipment. Heavier, consolidated parcels often benefit from better CPK rates compared to multiple small packages.

2. 2. Gather Quotes from Multiple Lines

   When ready to ship, request quotes from GTBuy for various available shipping lines (e.g., Air Cargo, Sea Freight, Express Couriers, Specialized Heavy Parcel lines). Ensure each quote includes the estimated weight (volumetric or actual)

3. 3. Calculate & Compare CPK Ratios

   Perform the CPK calculation for each shipping quote. Create a simple table to visualize the data:

   Shipping Line	Estimated Weight (kg)	Total Cost ($)	Cost-Per-Kilo ($/kg)	Estimated Time
   Air Economy	15.5	255.00	16.45	10-15 days
   Sea Freight	16.0*	120.00	7.50	35-50 days
   Express Heavy	15.0	310.00	20.67	5-7 days

   *Volumetric weight may apply. Always use the chargeable weight for calculation.

4. 4. Identify the Optimal Route

   In the example above, Sea Freightlowest CPKdelivery speed.

5. 5. Track and Record for Future Reference

   Maintain a log of your shipments, weights, costs, and carriers. Over time, you'll identify clear patterns—e.g., "For parcels over 20kg, Line X consistently offers the best CPK." This builds your own data-driven shipping intelligence.
