01 / INSTALL

From zero to first label
in ten minutes.

No "talk to onboarding." No multi-day setup call. Three steps, then your counter is live and the carrier-portal swamp is behind you.

STEP 01

Free ShipEngine signup

Open PostalSwift, paste your free ShipEngine API key during onboarding. Every carrier lights up at commercial rates instantly — no per-label fee from us.

STEP 02

Plug in FedEx & UPS (optional)

Have negotiated rates? Grab free developer API keys from FedEx Web Services and UPS Developer Kit, paste them in. Your accounts, your bill, your rates — we're not in the middle.

STEP 03

Hardware auto-detects

Plug in your USB scale, scanner, Dymo 4XL, receipt printer, cash drawer — PostalSwift picks each one up automatically. Scan a package, drop it on the scale, hit Rate Shop. Cheapest label prints. You're live.

System requirements

PostalSwift is a native Electron app — runs locally, sips memory, doesn't need a server.
