Disputing a charge on your account
Billing & Payments
3 min read Updated August 2026
If a charge on your invoice looks incorrect — a rate that doesn't match your quote, a surcharge you don't recognise, or a duplicate charge — raise it as soon as you notice it so it can be reviewed against your original booking and quote.
How to raise a billing question
Locate your invoice number and shipment reference — this lets our team look up exactly what was booked and quoted.
Note which line item looks wrong and why (for example "quoted at $X, invoiced at $Y").
Open a ticket under Support in the Client Portal, email billing@zargologix.com, or use Contact. Billing questions are reviewed by our finance team against the original quote and booking record.
Most discrepancies come down to estimated versus verified chargeable weight, or duties and taxes assessed at a different amount than the estimate — both are explained in Understanding your ZargoLogix invoice.
