Contractor invoicing guide
How to send an invoice that is easy to understand and pay
A practical guide to sending a professional invoice: what to include, copy-ready email and text examples, payment instructions, and a respectful follow-up schedule.
Short answer
Create an invoice with your business details, your client’s billing details, an invoice number, itemized work, a total, a due date, and payment instructions. Check the recipient, download the PDF, and send it with a short message explaining what it covers and when payment is due. Keep a copy and confirm payment before sending reminders.

A reminder that starts by checking with you.
Here’s an example of the overdue-invoice check and client text preview. It’s a demonstration—not a real conversation or delivery.

A friendly reminder from Corbin Ridge Repairs: invoice HM-2026-0412 for $615.10 is past due. Please check your invoice for payment details. If you’ve already paid, thank you!
Sending reminders requires membership. A client text follows your explicit “still unpaid” confirmation; silence does not trigger one.
1. Confirm who should receive the invoice
The person who hired you may not be the person who pays you. Before sending the first invoice, ask for the correct billing name, email address, and any purchase order or project reference. For a business client, ask whether invoices belong in an accounts-payable inbox or a supplier portal.
Agree on the scope, price, and payment terms before work begins. If the client needs a W-9 or other vendor paperwork, ask how to submit it securely. Do not put tax identification numbers into an ordinary text message.
- Confirm the billing contact and spelling of the client’s name.
- Include the project or purchase order reference if one is required.
- Ask about required paperwork and approval steps before the due date.
2. Build a complete, professional invoice
A good invoice answers three questions without another conversation: what am I paying for, how much do I owe, and how do I pay? Use specific descriptions rather than a single vague line such as “services.”
- Check quantities, rates, discounts, and the balance due.
- Apply taxes only when appropriate for your situation; verify applicable rules separately.
- Keep payment details accurate and never include account passwords or card details.
| Include | Useful example |
|---|---|
| Your name and contact details | Your business name, billing email, and business address |
| Client and project | Client’s billing name and website redesign project |
| Unique invoice number | INV-2026-014; do not reuse an earlier number |
| Issue date and due date | Issued October 25; due November 9 under agreed Net 15 terms |
| Itemized work | Homepage design: 6 hours × $85 = $510 |
| Total and prior payments | Show the total, any agreed deposit already paid, and remaining balance |
| Payment instructions | The agreed payment method and the verified recipient details |
3. Send the PDF with a short invoice email
Use a subject that the client can search for later. Attach the invoice PDF, mention the project and due date in the message, and make the next action clear. Avoid sending only an unexplained attachment.
The following is a fictional example. Replace the names, amount, dates, and payment instructions with your actual agreed details.
4. Use SMS when it is an agreed contact channel
A short text can draw attention to an invoice, but use a phone number the client provided for business communication and respect their preferences. Identify yourself, say which invoice you mean, and avoid sensitive financial information.
When using QuickDollar membership, choose the supported delivery channel and review the recipient before sending. A provider accepting a message is not proof that the client read it.
5. Make the payment method unambiguous
“Pay me by Venmo” is incomplete if the client does not know your correct username. State the agreed method and verify the destination before sending. If you change payment instructions, confirm the change through a trusted contact channel.
QuickDollar displays your payment instructions; it does not process the client’s invoice payment. The client pays you directly using your agreed method. Any fees or availability depend on that payment service, not on the invoice PDF.
- Use the invoice number as the payment reference where possible.
- Give the client a way to ask about payment instructions.
- Verify money has arrived before marking an invoice paid.
6. Follow up based on the facts, not just the calendar
First check whether payment has already arrived and whether the client reported a problem. If the invoice is overdue, resend the reference and remaining balance, ask whether anything is blocking approval, and keep the tone professional.
QuickDollar’s automatic payment checks ask the member whether an overdue invoice has been paid. An explicit “No” authorizes a client reminder; the system should not be described as blindly texting clients every day. Humorous reminders are optional—use them only when they fit the relationship.
| Situation | Next step |
|---|---|
| Invoice just sent | Keep the PDF and a record of where it was sent. |
| Client says they cannot find it | Verify the address and resend through the agreed channel. |
| Due date has passed | Check incoming payments, then send a concise reminder if still unpaid. |
| Client disputes the work or amount | Resolve the issue directly before repeating reminders. |
| Payment received | Record the payment and stop unnecessary follow-ups. |

Frequently asked questions
Can I send an invoice without an account?
You can create and download a QuickDollar invoice PDF without an account, then send it yourself from your own email. Sending through QuickDollar requires membership.
Should I send a PDF or just an email?
A PDF provides a consistent invoice document, while the email explains the context and next step. Sending both is often useful; follow the client’s required billing process.
Does sending an invoice guarantee payment?
No. Clear invoices and appropriate reminders can make the process easier, but payment depends on the client, your agreement, and any disputes or approval requirements.
How do I avoid sending a reminder after the client paid?
Check the payment account and update your records before reminding the client. QuickDollar’s automatic checks ask the member about payment before a client reminder is authorized.
