Tip four: Quarterly or Annual Billing. If your service has a consistent billing amount, ask your client if you can invoice them on a quarterly or annual basis? You may even be able to invoice them a base amount quarterly or annually and then send them a separate invoice that adjusts for additional services. Keep in mind that many large companies have annual budgets so it is not that uncommon for them to allow you bill annually, even annually in advance if you can do this at the start of their budget cycle.
