Can you Add a float value and cash up?

@RickH, what you’re asking for is indeed possible, but it’s a tall order.

You should look at the Tutorials for Payouts and Expenses done by both myself and @Jesse, and become familiar with the Accounting System in SambaPOS, then tailor it to your needs.

The original Tutorial is simple, and gets you started with adding Cash to float.

Then we have mine (Method Q) for Payouts and Expenses.

And @Jesse continued even further (Method K).
