We are experiencing incorrect tax amounts on all Best Buy Canada orders imported through the direct ShipStation connector. The tax information is correct in Best Buy, but ShipStation appears to add the marketplace commission tax to the customer’s sales tax.
Example: Order 268136723-A
| Tax detail | Amount (CAD) |
|---|---|
| Customer sales tax shown in Best Buy | $55.89 |
Tax on marketplace commission (commission_taxes) | $4.47 |
| Tax displayed in ShipStation | $60.36 |
The ShipStation amount equals $55.89 + $4.47 = $60.36. Based on the API response reviewed during our support chat, the additional $4.47 is tax on Best Buy’s seller commission, which should remain separate from the sales tax paid by the customer.
Troubleshooting completed
We refreshed the store, checked the activity log, and reconfigured the Best Buy connection, but the issue remains. We also provided screenshots of the discrepancy and API response to ShipStation Support.
The support agent advised that the issue would be escalated to the API team to review the connector’s tax field mapping.
Requested resolution
Please investigate the Best Buy Canada connector and ensure that only customer sales tax is imported into the order tax field, excluding commission_taxes. Please also confirm how existing affected orders can be corrected and provide an update on the escalation.
This is urgent for us because it affects the accuracy of our imported order totals.
