Gain unprecedented control over your transactions by participating in the authorisation decision.

Get in touch

Just-in-Time (JIT) Funding™ gives you unparalleled control of transactions by allowing you to automatically fund an account in real time during the transaction process.

This means you can:

Approve or deny each transaction based on your own business logic

Use your own rules, your own business logic, and your own data

Free up capital and improve cash flow

Maintain a zero balance on the card until you authorise and release funds in real time

JIT has been configured to work in one of two ways on our platform:

  1. Managed JIT – Allows us to make the authorisation decision, leveraging rules that you set on the platform
  2. Gateway JIT – Allows you to participate in the authorisation decision
