How to handle instalment plan in the Manager?

I need your advice on the instalment plan we provide to our customers, how would you handle it in the Manager? If the fee is $3000 and we provide a plan for 3 payments, would you provide 1 invoice and let it deduct from it or having 3 separate invoices reminding the customer of the due. Or any suggestion to simplify the step? Thanks

It’s really up to you what’s your preference. Both methods are OK especially if you pay taxes on cash-basis.

I personally would create 3 separate invoices though.
