Trunk is an inventory sync tool that keeps stock levels matched across sales channels in real time. When an item sells on one channel, Trunk updates the quantity everywhere else, which helps prevent overselling for makers, retailers and resellers selling on several platforms. It supports eBay, Etsy, Shopify, Amazon, Walmart, Square, WooCommerce, Faire, Bandcamp, Limited Run, Goldbelly, Tundra, AIMS360 and QuickBooks Online. Features include low stock alerts, smart bundles and kits, and syncing duplicate SKUs within the same channel. Every plan includes unlimited sales channels and listings, and price is based on the number of fulfilled orders per month. Support is handled through live chat, email and an Intercom help center.

Open Billing in Trunk and look at Payment Method. If it says Shopify, you are billed through Shopify, so uninstall Trunk from your Shopify store to cancel automatically. If it lists a credit card, you are billed through Stripe; contact Trunk by live chat or email hello@trunkinventory.com and they cancel it right away.
Yes. Trunk's help center has an eBay collection covering which eBay regions and marketplaces are supported, adding SKUs as custom labels on eBay listings, syncing stock between multiple eBay stores, and why listing variants disappear when they go out of stock. eBay listings need SKUs so Trunk can link them to other channels.
An order is one customer purchase, even if it contains many items, and stock level changes are not counted. Canceled orders are not counted because only fulfilled orders are billed. About a week before each billing cycle Trunk rechecks your monthly orders and moves you up or down a tier automatically, with a notification.
The contact page offers live chat and email, and asks you to disable ad blockers so the chat widget loads. The help center confirms you can reach a human through the chat icon at the bottom right. Articles cover each supported sales channel, account management and pricing.
