As another option, utilize a 3rd party payment service.  Your client may stretch their cash flow by creating up to a 45-day float by paying bills via a credit card, even if you don’t accept credit cards. You will get paid with a physical check or with electronic bank transfers. They will make a payment with a total sum of numerous invoices together and in the “Note to self” and “Note to vendor” fields input the different invoice numbers. Thereby letting you as vendor know the payment is for several payments.
