Frequently Asked Questions

How does TomeSync handle one-of-a-kind items?
TomeSync is purpose-built for single-copy inventories. Our engine treats catalog items as unique entities. The moment a transaction is detected (via live webhook listeners), the engine instantly locks the master DB record and updates remaining channels to zero before the buyer transaction fully propagates, preventing duplicate sales.
What marketplaces does the engine support?
TomeSync currently supports direct real-time integrations for eBay, Shopify, WooCommerce, Holiday Book Co, and dynamic custom webhooks. We have AbeBooks, Biblio, and Amazon SP-API integrations currently in private development.
How does the 7-day trial and subscription work?
When the app goes live, you can register and connect your first channel for free. After 7 days, to maintain real-time sync across multiple active channels, you will be prompted to subscribe to the flat $25/month tier. There are never any setup fees or percentage fees on your books.
How can I join the private beta?
Simply submit your professional email address in the waitlist form at the top of this page. Since we are restricting access to a limited number of antique and rare book dealers during our early launch, we will review your shop information and send you a private invite link once your slot is ready.
