When modelling invoice financing within Float the general rule of thumb is to budget for the drawdowns from the financing facility rather than for the individual invoices.
Any invoices which are included in the financing agreement should be excluded from the cash flow, with budgets then entered to reflect when the cash from the financing facility will be drawn into the bank account.
For example, if 80% is available when an invoice is raised, a budget for 80% of the value would be entered into the cash flow with a budget for 20% set for later when the remaining 20% will be released.
This is a simplified example and all situations can vary so if you have any questions around the specifics of a given situation just drop us a message.
