For marketplaces and apps
Labels for your sellers, rules included
Gun and gear marketplaces can’t just bolt on a generic label app: the rules differ for every item, seller and state. SmoothShip handles that, so your sellers print a correct label without leaving your site.
What the API does
- Check: the rules for an item, seller type and destination, with sources.
- Rate: USPS, UPS and FedEx prices for the lanes the rules leave open, our pick marked.
- Buy: the label, insurance and the required statements, kept on record.
- Track: tracking and carrier adjustments by webhook.
How your sellers pay
Each seller gets a SmoothShip balance under your platform. Money never mixes with your item payments, and your checkout stays your own. Dealers can connect their own UPS and FedEx firearm accounts.
