Terms of use

Last updated: 2026-11-11.

These terms are between you and Tenhatch (“we”), Calabasas, CA, USA, support@tenhatch.com. By installing or using PastDue you agree to them for the business whose Stripe account you install it in.

What PastDue does

PastDue adds the late fee or interest you set to your Stripe invoices that are past their due date, and gives your customer a statement of what they owe. It acts in your Stripe account with the permissions you accept, once a day and when you press "Check overdue invoices now". It starts in preview, which charges nothing.

Your fees are your responsibility

You decide whether to charge late fees or interest, how much, and to whom. You are responsible for making sure your rule is allowed by the law that applies to you and your customers, and that your customers agreed to it. PastDue charges exactly the rule you set. PastDue is not legal, tax or accounting advice. Check each fee it adds, and stop or void any that should not be there.

Free and Pro

• Preview is free: PastDue shows the fees it would add and charges nothing.
• PastDue Pro adds the fees and sends the statements for one Stripe account: $19 a month or $190 a year, paid in advance on Stripe's checkout, with the first 14 days free. Sales tax may be added where the law requires.
• Plans renew automatically. You can cancel at any time from the link in your receipts or by writing to us; Pro then stays on until the end of the period paid for. Uninstalling the app does not cancel Pro by itself.
• Refunds within 14 days of a charge, no questions asked: write to us.

Stripe

PastDue is an independent product by Tenhatch. It is not made or endorsed by Stripe. Stripe is a trademark of Stripe, Inc. PastDue depends on Stripe's services; how Stripe treats your invoices and emails is set by your agreement with Stripe.

Fair use

Use PastDue only for your own business's invoices and within the law. Do not try to get around its plans, copy or resell it, or interfere with its service.

No warranty, and limits

PastDue is provided as is. We work to keep it running as Stripe changes, but we make no promise that it runs without interruption or that every fee is added on its exact day. To the extent the law allows, we are not liable for indirect or consequential losses, and our total liability is limited to what you paid us for PastDue in the 12 months before the claim.

Changes and law

We may update these terms; when we do, the date at the top changes. These terms are governed by the laws of California, USA.
