1. Book review queue

A book must be checked before export. The eBay CSV creates drafts, not live listings, and does not include private image URLs. Add scans to eBay when reviewing the draft.

2. Upload book scans

Choose the original front and rear JPEGs from your Mac. Originals are stored privately in Supabase. The rear scan is the best place to read an ISBN.

Text recognition runs in your browser and may take time on the first use. It suggests text; always check the edition. No automatic crop is applied to original scans.

Open a book with Edit, then select “Identify & Research Book”. You can also use newly selected scan files.

Illustrative eBay fee estimate: 10.25% plus 30p per order up to £10 (40p above £10), before possible VAT on fees, promotions and other charges. Check the actual fees for each product category. Do not treat these as confirmed eBay charges.

4. Measurements & automatic postage

Check the book measurements; ResellerRobot recommends the D/1 or E/2 envelope and Royal Mail 2nd Class Click & Drop price. You do not have to choose a postal class. Final packed thickness and weight should be checked before buying the label.

Automatic Mac scan arrivals

For hands-free uploading, run the ResellerRobot Mac helper. It creates new entries in the Review Queue above as each front/rear pair arrives. Click Refresh inventory to see the new arrivals. Newly arrived books are automatically checked for ISBNs while this page is open; any results require your review. The manual batch uploader remains available as a backup.

Automatic ISBN lookup is available for new scans. Your existing edits and measurements are preserved.

Manual batch upload (backup)

Choose the scanned JPEG files together (you can select all in Finder). Odd scan numbers are fronts and the next even number is the back. Review every pair before saving. This does not watch the Mac folder in the background.

Select scanned images

Choose Scan 1.jpeg, Scan 2.jpeg, and so on. Missing, repeated or unnumbered files will be flagged.
