Before you start

  • You know the total job amount.
  • You know when the customer should be billed for each part of the work.

When to use a payment schedule

Use a payment schedule when one invoice at the end is not enough. Deposits, progress billing, fixed milestones, named schedules, and final-balance invoices help the office collect cash while longer work is still underway.

Do this

  1. 1

    Start from the quote or job

    Open the quote or job that needs staged billing before creating invoices.

  2. 2

    Choose the billing style

    Pick deposit, remaining balance, percentage, fixed milestone, or named payment schedule based on how the customer agreed to pay.

  3. 3

    Name each step clearly

    Use labels like Deposit, Materials, Phase 1, Completion, or Final Balance so the customer understands why the invoice arrived.

  4. 4

    Review due dates and amounts

    Confirm every step has the right amount, due date, and customer-facing note before sending.

  5. 5

    Track what is already billed

    Before sending the next invoice, check the job billing summary so you do not double-bill or skip the final balance.

Most common mistake

Owners often create a manual invoice without checking the job's billing schedule first. Start from the job or quote whenever possible so the invoice stays connected to the approved work.
