How to Automate Recurring Invoices for Retainer Clients

The Retainer Opportunity: Why We Need Automated Billing

Signing retainer clients is the best way to secure recurring revenue. But creating the same monthly invoice for $5,000, sending it to the client, and following up on payments is a chore. Automating this process with recurring invoice software keeps billing on time and secures your cash flow.

The problem is manual entry. If you manage 10 retainer contracts and create invoices manually, it is easy to forget to bill or make errors. Automating invoices ensures they are sent on time, every time, reducing payment delays.

  2. Intervals: Set the billing frequency (e.g. Monthly, Weekly) and the start date.
  3. Action: Choose to save as a draft for review or send automatically.
