Split Payments will be enabled in new Floranext systems by default.
If you need to add this setting, go to Settings > POS Settings > POS Settings and find the option for Split Payments. Set this to Enabled and save.
The option will appear in the Take Payment menu of the Take Order screen:
To split a payment across different tenders, in the payment amount screen you will select the type of payment and enter the amount of the first tender, then click the "+ Split Payment" link in the corner. You can split payment among up to 5 different payment types.
NOTE: Split Payments can only be processed from the Take Order Screen. Orders that have already been processed as COD/Pay Later payment method cannot be paid for with split payments.
