EDIT

I apologize for misunderstanding the question.

one of the options I could find was

Payment Instruction

where you could specify the transaction as "Incoming" or "Outgoing"

As thomj1332 pointed out "Money Flow" is also an option

One of the options I find is:

Payment Instruction

where you can specify the transaction as "Incoming" or "Outgoing".

I think these words can describe what you need

For "Incoming"

Influx

Definition of influx

noun: influx; plural noun: influxes

an arrival or entry of large numbers of people or things. "a massive influx of tourists"

an inflow of water into a river, lake, or the sea. "the lakes are fed by influxes of meltwater"

For "Outgoing"

Efflux

noun: efflux

1. the flowing out of a substance or particle. "the same active efflux of sodium from the cytoplasm to the external medium" material that is flowing out.

I found this appropriate for your needs since you are dealing with money, these words are used in describing the flow of money
