If I give credit terms of 30 days to my debtor/customer, but they only pay 60 days after my credit term, will my debtor/customer be penalised by Finaxar?

Finaxar will not penalise your debtors/customers. 

Do note however that debts are monitored based on the financing period after an invoice's issuance date. Assuming we approved your debtors/customers for a 90 day financing period, if we do not receive your debtors/customers' payment within 90 days, our system will automatically classify these invoice(s) as ineligible. This will impact the amount of available funds you can draw down.
