When to use this template

Prepare billing details online, then generate an invoice PDF ready to send. Use this after work is completed or at a milestone payment point defined in the contract, to formally request payment from the client for services rendered and materials supplied.

What to include

  • Invoice number, invoice date, payment due date, and reference to the contract or work order number so the client can match the invoice to the approved job.
  • Itemized line items matching the contract breakdown: description of each task completed, quantity, unit price, and extended amount for labor and materials separately.
  • Credits and adjustments: deposit already received, progress payments applied, retainage withheld, approved change order amounts, and any discounts.
  • Payment instructions: accepted payment methods, bank account details for wire or ACH, mailing address for checks, and late payment penalty terms.
  • Total amount due, payment terms (Net 15, Net 30), and a note referencing the completion certificate or sign-off that confirms the work was accepted.

Common questions

Can I create and edit this Invoice online before issuing it?
Yes. Update line items, taxes, due dates, and payment terms in-browser before export.
Can I save this Invoice format for recurring billing?
Yes. With an account, save it and reuse billing structure for repeat customers or milestone invoices.
Can I generate a client-ready PDF from this Invoice?
Yes. Export a clear PDF invoice you can email immediately or attach to your accounting flow.
Should I invoice at completion or at milestones?
For jobs over a few thousand dollars, invoice at milestones defined in the contract. This keeps your cash flow steady and reduces the risk of a large unpaid balance.
What if the client disputes a line item on the invoice?
Ask the client to pay the undisputed portion immediately and resolve the disputed item separately with documentation from the contract or change orders.
Do I need to include my license number on the invoice?
Some states require it. Including your license and insurance information on every invoice reinforces professionalism and may be needed for the client's records.
How should I number my invoices?
Use a sequential system that includes the year, such as 2026-001. This makes tax filing and payment tracking simple as your business grows.
How do I get customers to pay faster?
Send the invoice immediately after completing the work, include clear payment terms and a due date, and make it easy to pay. A professional invoice with a specific deadline gets paid faster than a casual text.
What should I do about late-paying customers?
Follow up with a past-due notice after the payment deadline. Having a documented invoice with clear terms makes it much easier to collect or escalate to collections if needed.
Should my invoice match my original estimate?
Yes. If the final amount differs from the estimate, the invoice should clearly show what changed and reference the approved change order. Surprises on the invoice destroy customer trust.
