Switching from billing in arrears to billing in advance is one of the most impactful changes a pool service company can make — and one of the trickiest to communicate to customers. This free template gives you a ready-to-use transition schedule and customer-facing explanation to make the shift clear, professional, and low-friction.

A clear transition schedule Includes a sample three-invoice transition timeline that eliminates gaps and overlaps, so customers are never double-billed or left confused about what a given invoice covers.
Customer-ready language The explanation section is written for your customers, not your accountant. Plain language, no jargon, and a professional tone that reinforces trust.
Flexible and customizable The sample dates and service periods are examples — not prescriptions. Adjust the timeline to match your actual billing cycle and start date.
One less thing to write from scratch The hardest part of this transition is the communication. The copy is already done.

Is this the only way to transition to billing in advance?
No. This template represents one suggested approach. Your specific timing, customer base, and billing cycle may call for a different schedule. Use it as a starting point, not a strict rulebook.
Why does the transition require two invoices in one month?
The two-invoice month bridges the gap between the old model and the new one. It ensures no service period goes unbilled while avoiding double-billing customers for the same time window.
What happens if a customer's service changes mid-month?
The template includes language explaining that mid-month additions or cancellations will be handled with a pro-rated adjustment or credit, keeping the billing accurate without requiring a full invoice revision.
Do I need to be a Skimmer customer to use this?
The template is designed with Skimmer users in mind, but the transition schedule and customer communication are applicable to any pool service billing workflow.
