Nautilus connects to the UPS Developer API for label generation, rate comparison, and tracking. Like the FedEx integration, customers with their own UPS account use their negotiated rates.
Inventory data, where you need it.
Three things the UPS integration does well, that you'd otherwise be doing by hand.
Rate shopping
Compare UPS Ground, 2nd Day Air, Next Day Air Saver, and Next Day Air rates before printing. Service level rules can be configured per order weight, declared value, or required delivery date.
Access Point delivery
Route shipments to UPS Access Points (pharmacy and convenience store locations) for customer convenience and signature-on-pickup security. Useful for high-value or apartment-complex deliveries.
SurePost
UPS SurePost (UPS Ground Saver) is supported for lightweight residential deliveries. The package ships UPS Ground and is handed off to USPS for last-mile delivery, which is cheaper than UPS Ground but slower. Best for low-margin products.
Bidirectional sync. No manual entry.
Data moves between Nautilus and UPS in both directions, near-real-time.

Four steps to live.
The same four steps whichever platform you connect.
Connect
Authenticate with one click. Nautilus uses OAuth — no API keys to copy, no credentials to store.
Map
Match your products, locations, and accounts. Nautilus auto-maps by SKU where possible.
Sync
Turn sync on. Changes made in either system carry over to the other automatically.
Verify
Run the sync health check. Nautilus flags any mismatches before they become problems.
What the integration does, in numbers.
UPS questions, answered.
Yes. The UPS Developer API requires a UPS account number and shipper account. Customers without one can use UPS through ShipStation or Shippo instead. The UPS account signup process is straightforward but approval isn't instant; plan accordingly.
UPS Ground is end-to-end UPS delivery. UPS Ground Saver hands the last mile to USPS, which is typically slower and cheaper. A common split is Ground for higher-value items and Saver for low-margin items where the delivery date is less critical.
Yes, but with one rule: pick one tool to be the label generator. We recommend moving all label generation into Nautilus and retiring UPS Worldship for that account. If you have non-Nautilus shipments (internal transfers shipped through UPS), Worldship can handle those separately without conflicting.
Surcharges come back from UPS's rate API at quote time. The quotes Nautilus shows include surcharges, so packers see the actual final rate, not a base rate that has hidden costs added later. During peak season (typically mid-November through January), UPS's peak surcharge updates weekly; Nautilus picks up the changes automatically.
