When to Send an Invoice: Best Practices for Getting Paid Faster

Timing is everything when it comes to getting paid. Research shows that invoices sent within 24 hours of project completion are paid 1.5x faster than those sent a week later. Here is how to optimize your invoicing timing.

Send Immediately After Completing Work

The best time to send an invoice is the same day you finish a project or milestone. The work is fresh in your client's mind, they are satisfied with the result, and they are most motivated to process payment quickly.

Use Milestone Billing for Large Projects

For projects over $5,000, consider breaking payment into milestones: 50% upfront before starting, 25% at a midpoint, and 25% on delivery. This protects your cash flow and reduces risk if the project scope changes.

Set Up Recurring Invoices for Retainer Clients

If you have clients on monthly retainers, set up recurring invoices so you never forget to bill. InvoiceQuick Pro handles recurring billing automatically — set the amount, frequency, and start date, and invoices go out on schedule.

Avoid Invoicing at the Wrong Time

Don't send invoices on Friday afternoons (they get buried over the weekend), on holidays, or during known busy periods for your client. Tuesday through Thursday mornings tend to get the fastest response rates.

Follow Up Before the Due Date

Send a friendly reminder 3-5 days before the invoice is due — not after. A proactive nudge is less awkward than a collection call and gets you paid without damaging the relationship.
