At The Maven Group, we bill all partner customers monthly. This happens on the 15th of every month. At this time, an invoice with your fixed monthly charges will be sent to you including any additional one time charges incurred during that month (i.e. new equipment, supplies, etc.).
For example. On approximately January 15 of a given year, you will receive your monthly invoice. Terms on the invoice are NET10 and due for that period of monthly service. You will then receive another invoice on Feb 15 and so on. We only bill monthly to our customers and accept payment via check, but special needs can be accommodated to fit payment systems, etc.
NOTE: As of 04/20/2017, we are still working with QuickBooks support to remedy an issue where random invoices are being sent for the forthcoming month automatically without our intention. Please note that payment is due ONLY for the month of the invoice. For example, if you receive a July invoice in June, the July invoice is not due. You will receive another invoice (same invoice number) on the 15th of July which includes the correct amount due at that time. I apologize for the inconvenience.
Let me know if you have any questions or need any special arrangements.
