I have made my living as an IT consultant for over 23 years. I have always invoiced monthly and both my clients and I have been very pleased with this cycle.

Inundating one's clients with invoices increases their overhead and yours. It adds the risk of invoices being lost and can create discomfort on the part of the client by causing them to feel like they're being nickel and dimed to death. In addition there are plenty of times each month when a client needs remote support that takes only 15 minutes (my minimum time increment) - would the author of this article have me bill a client for 15 minutes several times a month? Or should I eat this time? Neither approach is fair or reasonable.

Who among us would put up with getting an invoice from our credit card companies each day we charge something? Companies are accustomed to monthly billing cycles for any service they depend on, be it credit cards, electricity or IT support.
