Frequently Asked Questions
Can I sync inventory from a supplier CSV file automatically?
Yes, you can point syncX to a CSV file hosted on an FTP server, HTTP URL, or upload it manually. On paid plans, the app will fetch and process the file on a schedule as frequently as every 15 minutes.
Does it work with multiple suppliers at the same time?
Yes, paid plans support multiple feed sources. Each feed can have its own format, field mapping, and sync schedule, so you can aggregate inventory from several suppliers into one Shopify store.
Can I export my Shopify inventory to other channels?
Yes, the Pro plan includes inventory export feeds that you can provide to third-party marketplaces, warehouses, or partners, keeping your stock data flowing in both directions.
How does the bundling feature handle inventory?
When a bundle sells, Trunk automatically deducts the correct quantity of each component product from your inventory. If a component runs out of stock, the bundle is also marked as out of stock to prevent overselling.
Can Trunk sync inventory between Shopify and external marketplaces?
Yes, Trunk syncs inventory in real time across Shopify, eBay, Etsy, Amazon, Walmart, and other channels. Stock changes on any connected channel are reflected everywhere within seconds.
Does it support multi-location inventory in Shopify?
