How Invoice Emails Work (and the Free Cap)

Two ways to deliver an invoice

Every invoice has a public URL. You can copy the link and send it however you want (text, email, DM) — that doesn't count against any quota and works on every plan. You can also click Send Invoice from inside the app, and WaffleInvoice emails the invoice through our delivery infrastructure with your branding.

The 25/30-day free cap

Free accounts get 25 invoice email sends per rolling 30-day window. "Rolling" means we look back 30 days from now, not at calendar months. So if you sent 5 emails on day 1, by day 31 those 5 are no longer counted and you have them back.

• Only invoice emails sent via Send Invoice count.

• Copy-link shares do not count.

• Estimate emails do not count.

• Resends of the same invoice each count once.

• Failed deliveries we retry do not double-count.

The 5/day cap for new accounts

Brand-new accounts (less than 14 days old) also have a 5-emails-per-24-hours cap. This is layered on top of the 25/30-day cap as a fraud guardrail — fraud rings tend to spin up an account and immediately fire off dozens of invoices, and the daily cap stops that pattern cold without slowing real users down. After 14 days, the daily cap automatically lifts.

What you see when you hit a cap

When you click Send Invoice and you've hit either cap, you'll see a modal explaining which cap was hit and how many hours until it resets. You'll also get an Upgrade to Pro button that lifts both caps immediately.

What still works when you're capped

• Creating and editing invoices.

• Sharing the invoice link manually (copy + paste).

• Downloading invoice PDFs.

• Recording manual payments.

• Sending estimate emails.
