Help us find the problem

Include your Gruffin username, app version, Windows version, what you were doing, and the exact error message. For billing issues, include the billing email and Stripe receipt or invoice number.

Connections and dashboard

Connect from Settings → Connections → Connect eBay Seller Account. Review eBay’s permissions in your browser, return to Gruffin, and refresh connection status. Then open Dashboard → Refresh. Sales analytics require Professional or Enterprise access.

Product research

Try an exact brand and model, barcode, or ISBN. Review the source and variant before using imported details. New web research can take time. If a result looks wrong, send the search text and a description of the mismatch so we can investigate.

Subscriptions and cancellation

Open Subscription in Gruffin to view your plan, refresh billing status, open the Stripe billing portal, or cancel future renewals. Contact support if you cannot access cancellation controls. A website account is separate from your desktop workspace.

Refunds and privacy

Read the 30-day subscription Refund Policy for refund requests. For privacy or data requests, see the Privacy Policy and contact support.

Sales are not updating inventory

Refresh Orders and confirm that the payment is complete. The eBay custom label, Gruffin SKU, and linked Excel item ID must identify the same item. Gruffin uses exact matching rather than guessing from a product title. An unmatched order is left unchanged. Repeated refreshes do not deduct a recorded sale again.

Receiving a return

Use Returns to check the marketplace feed and select an awaiting-arrival request. Record physical receipt and inspection before adding units back to sellable stock. Damaged items can be received and held out of stock; partial arrivals can leave the request open. Refund-only outcomes do not move inventory. Log refunds here after handling the actual money through the original provider.

If an older request lacks its original quantity or order value, refresh marketplace returns before receiving it. Feed lookback limits may restrict older order details. Contact support with the order ID and SKU if the original details are unavailable.

Excel permissions, conflicts, and changed headings

Excel sync is started from Inventory and reviewed before applying. Write-back is off until you enable it for the linked workbook. To stop linking, open Workbook setup and choose Unlink workbook; the spreadsheet remains intact.

If both sides changed, choose the correct value in the preview or leave Skip selected. If a sale or an Excel edit occurs after preview, close it and create a fresh comparison. Close Excel before write-back. Gruffin creates a backup before approved Excel writes and reports its location when the sync completes.

Reordering source columns is supported when headings stay the same. If Excel headings are renamed or duplicated, review the mapping instead of forcing a sync. App heading changes made through Column names do not change the mapping. Formula cells, protected worksheets, and unmapped columns are not overwritten. Sync does not append or delete Excel rows.

For older .xls workbooks, save a copy as .xlsx to use linking. CSV and .xls imports remain available separately. Keep long identifiers and identifiers with complex number formats as text in Excel so their exact digits are preserved.
