Automatic payment reminders

What reminders do

Mortar can email clients on your behalf when an invoice is coming due or overdue, so you don't have to chase payments manually. Reminders go out at three points:

Only one reminder goes out per invoice per check — a client won't be double-emailed if more than one stage becomes eligible at once.

Reminder emails are written in a warm, designer voice — they read like a nudge from your studio, not a collections notice — and always state the current amount actually outstanding (not the original invoice total, so a partial payment is reflected).

Turning reminders on or off

Reminders are on by default for every studio — there's nothing to switch on to start using them.

• Studio-wide: Settings → Billing has a toggle to turn automatic reminders off (or back on) across all your invoices.
• Per invoice: an individual invoice can be paused from its detail page if you're handling that one directly with the client and don't want an automated nudge going out.

Reminders only go out for invoices that: have a due date, aren't drafts, aren't void, and still have an outstanding balance.

FAQ

Will reminders go out for old invoices the moment I turn this on? No — there are launch-safety limits so a studio's reminders don't suddenly email every unpaid invoice it's ever sent. An invoice more than 30 days overdue won't get the first overdue reminder, and one more than 60 days overdue won't get the second — only invoices in their normal, current window get chased.

Can I customize the reminder wording? Not per-invoice today — reminders use a fixed studio-branded template. Contact support if you need a specific exception.

Does a reminder count as "resending" the invoice? No — reminders and manually clicking Resend on an invoice are separate. Resending uses the same email but is something you trigger yourself; see Creating and sending invoices.
