Extend Your Payment Layer.
Add card-present switching and a white-label gateway to your platform. Field39 connects via API as another provider in your stack — so you can offer POS, e-commerce, and terminal management without a 12-month build.
Your merchants need more than online payments.
Platforms that handle e-commerce well still leave card-present and terminal demand on the table — and a white-label gateway is a revenue stream most never tap.
No Card-Present Infrastructure
Your platform handles online, but your merchants also need to take payments in person — at the counter, the table, or the kiosk.
ISVs Want Embedded Terminals
Retail, hospitality, parking, and events software all want terminal payments built into the platform — not bolted on by a third party.
White-Label Gateway Revenue
Offer your merchants a gateway they can brand as their own — a new revenue stream that runs on infrastructure you control.
Field39 plugs in as another provider in your stack.
Switch39 and IPG39 connect to your orchestration layer over HTTP/JSON — adding card-present switching and a white-label gateway behind your existing routing.
New channels, new revenue, no rebuild.
Extend the platform you already run with capabilities your merchants are asking for — on predictable, per-transaction pricing.
Card-Present Channel
Add POS and terminal payments to your platform via Switch39 — the channel your merchants need but you don’t have today.
White-Label Gateway
Offer your merchants a gateway they can brand as their own, running on IPG39 behind the scenes.
Multi-Acquirer Routing
