Paladin Data Corporation builds Paladin Point of Sale, a retail POS and inventory management platform for hardware, lumber/building supply, pharmacy, feed/seed, pet, and general retail stores. An unofficial API lets you programmatically pull inventory, item pricing, stock-on-hand, customers, and sales/invoice data—and push updates like new invoices, stock adjustments, and online orders back into Paladin.

Paladin Data Corporation is an independent retail software provider with 45+ years of industry experience, best known for Paladin Point of Sale—a point-of-sale and inventory management platform for independent and multi-store retailers. Stores use Paladin to run checkout, manage inventory and pricing, process purchase orders, connect to distributor EDI networks, and bridge in-store and online sales.

Supergood reverse-engineers authenticated Paladin sessions and the eCommerce API surface to deliver a resilient, normalized API layer over your Paladin Point of Sale deployment—across single-store and multi-store operations.

Yes. Supergood handles per-store sessions and rolls inventory, sales, and purchasing data up across locations, so multi-store retailers integrate once instead of per install.
Paladin provisions API credentials through its client portal and support. Supergood works with your provisioned access and authenticated sessions, and we help confirm the right setup during the integration assessment.
Hardware, lumber, pharmacy, and feed/seed stores carry different units of measure, attributes, and EDI catalogs. Supergood preserves store-specific item fields rather than forcing a generic schema.
Yes. Supergood pulls stock-on-hand and pricing and pushes updates back as orders are captured, keeping PaladinShop and third-party storefronts consistent with in-store inventory.
