What it does
Trunk connects sales channels and keeps their stock quantities linked by SKU. Pro adds bundles and duplicate listings within the same channel. A signed-in account is required; all features are available in a 14-day trial without a card, then a paid plan is needed.
Trunk normally links matching SKUs across different sales channels. Within one channel, it links only one listing per SKU and flags duplicates. If two listings deliberately sell the same item, open that channel's Advanced settings and enable duplicate-SKU syncing. Linking starts immediately; a parenthesized number shows how many listings share the inventory record.
Pro's bundles let singles and multipacks draw on shared components. An assembled product can depend on available parts. Each bundle has fixed dependencies: customer-designed combinations need their own SKUs and configurations.
Essential starts at USD 35/month and Pro at USD 39/month for up to 100 orders. Both allow unlimited channels and listings; higher order volumes cost more. Pro includes bundling and duplicate-SKU controls. Before each billing cycle, Trunk can move the account's volume tier up or down with notice. Stock adjustments are not orders.
To inspect the order count, open your account name > Settings > Billing. A subscription is required after the trial.
