Pro Tips for Enhanced Accuracy
Account for Volumetric Weight
For lightweight, bulky items, carriers charge based on volumetric (dimensional) weight. Note which shipments incurred volumetric charges to better predict when it will apply.
Segment by Shipping Line
Different lines (EMS, DHL, SAL) have vastly different pricing structures. Calculate separate averages for each line you regularly use.
Include Exchange Rates & Fees
Log the final charged amount in your local currency, including any payment processing fees, for a complete view of your expense.
Take Control of Your Logistics Budget
Turning the LoveGoBuy spreadsheet into a predictive tool requires minimal effort but delivers maximum financial clarity. By consistently tracking weights and fees, you move from reactive paying to proactive planning. Start logging your next shipment—your future budget will thank you.
