THE PLATFORM
DeltaRate brings your orders, shipments, rate cards and invoices into one place. It works out what each shipment should have cost, compares that with what you were billed, and shows your team exactly what matched, what didn’t and what needs review.
Free during beta. Built for ecommerce finance and operations teams.

ONE PLATFORM, THREE JOBS
Expected cost
Know what every shipment should cost before you approve the invoice. DeltaRate applies your agreed rate cards to your shipment details to calculate an expected cost for each charge.
Discrepancy checking
Compare every billed line with its expected cost. Incorrect rates, duplicate fees and unexpected surcharges are flagged with the evidence behind them, ready to dispute or ignore.
Spend visibility
See how couriers, warehouses, services and surcharges add up, and which orders are profitable once logistics costs are counted.
KNOW THE EXPECTED COST
Every courier and 3PL invoice is a claim about what you owe. DeltaRate tests that claim against your own data. It reads the shipment details (weight, dimensions, service, destination) and applies the rate card you agreed, so each charge has a clear expected cost.
• Rate cards applied per shipment: your agreed rates, not list prices.
• Courier and 3PL charges: delivery and fulfilment costs checked in the same place.
• Rate card versions tracked: the right rates applied for each shipment date.

FIND BILLING DISCREPANCIES
Manual spot checks miss what volume hides. DeltaRate compares billed amounts with expected costs across the whole invoice, not a sample, and flags where they differ.
• Incorrect rates: charges that don’t match your agreed rate card.
• Duplicate fees: the same charge billed more than once.
• Unexpected surcharges: fees that appear late or weren’t expected for that shipment.
• Weights and fees: weight and dimension recalculations, fuel surcharges, remote area fees, and 3PL fees for pick and pack, storage and handling.

SEE WHAT NEEDS REVIEW
Some charges can’t be checked because something is missing: no matching order, an unknown service or an incomplete rate card. DeltaRate doesn’t guess. It shows which charges couldn’t be checked and why, so your team knows exactly what to fix.

REVIEW THE EVIDENCE
Every result comes with its working: the billed amount, the expected cost, the rate applied and the shipment data behind it. Finance can approve with confidence. Operations can raise a query with the facts in hand.
When a charge is wrong, DeltaRate helps you prepare the dispute. Record the outcome, whether credited, refunded or otherwise, so you can see what has been recovered. Not worth chasing? Ignore it and move on.

COMPLETE VISIBILITY
Analysing invoice charges alongside order and shipment data shows which orders are profitable, which aren’t, and where logistics costs quietly outweigh margin. Break spend down by courier, warehouse, service and surcharge, and spot the patterns behind rising costs.

WHAT WE CHECK
Shipping and fulfilment invoices are hard to check by hand. Rates change, surcharges appear late, weights and dimensions get recalculated, and every courier and 3PL formats data differently. DeltaRate checks:
✓
Missing data detection
Flags line items with missing or incomplete data.
✓
Shipping zone verification
Checks billed zones against the courier’s zone tables.
✓
Duplicate charge detection
Finds charges entered twice on the same invoice.
✓
Billed weight verification
Checks billed weight against actual and dimensional weight.
✓
Shipment charge consolidation
Groups charges by tracking number to show whether each shipment is billed in full across invoices.
✓
Cost comparison
Compares pre-invoice cost estimates with what you were actually charged.
✓
Shipment weight mismatch
Compares your Shopify fulfilment weight with the billed weight.
✓
Cross-invoice double billing
Spots tracking numbers billed on more than one invoice.
✓
Fulfilment date mismatch
Compares your Shopify fulfilment date with the shipment date on the invoice.
✓
Delivery rate validation
Checks delivery charges against the ceilings in your uploaded rate card.
✓
Fuel surcharges and remote area fees
Checks these extra charges are applied correctly.
✓
3PL fulfilment fees
Checks pick and pack, storage and handling fees against your agreed rates.
