How Agencies Can Automate Client Payment Reminders

Agencies rarely bill just one client. Between retainers, project invoices, and one-off work, keeping track of who owes what and when to follow up becomes its own job. Manually checking due dates and emailing clients about unpaid invoices takes time, and it’s easy for an overdue invoice to slip past unnoticed when you’re managing several at once.

Luckily, this process is easily simplified using the right automation tools.

Introducing Direct Invoices

Direct Invoices by Digages is a WordPress plugin that lets you build payment reminders directly into your invoicing workflow, so you’re not manually tracking due dates or sending follow-up messages client by client. Once configured, reminders go out automatically based on the due date you’ve set on each invoice, i.e., before it’s due, and again if it becomes overdue, reducing the manual follow-up work that eats into an agency’s time.

Setting Up Automated Invoice Reminders

Here’s how reminders work in Direct Invoices and how to configure them.

1. Where Reminders Are Configured

Go to Invoices → Settings → General → Invoice Preferences. This is where the reminder system lives, alongside your other invoice-wide preferences like currency and starting invoice number.

2. Which Reminder Settings Are Available

Under Invoice Preferences, you’ll find:

  • Automatically remind customers about unpaid invoices — a toggle to turn the reminder system on
  • Auto Reminder: Days Before Due Date — configures how many days ahead of the due date a reminder is sent
  • Auto Reminder: Days After Due Date — configures a follow-up reminder if the invoice becomes overdue

3. How Reminder Timing Works

You set the number of days for each of the two settings above. For example, setting “Days Before Due Date” to 3 sends a reminder three days ahead of the deadline, and setting “Days After Due Date” to 2 sends a follow-up two days after it’s passed without payment.

4. How Reminders Relate to Invoice Due Dates

Reminders are tied directly to the Due Date you set on each invoice under Invoice Details. Without a due date, there’s no anchor point for the reminder schedule to work from, which is why setting one on every invoice matters, not just for record-keeping but for the reminder system to function at all.

5. How This Helps Agencies Follow Up with Clients

Once configured, this setting applies across your invoices, meaning you don’t have to remember to follow up with each client individually. The system handles the before-due-date nudge and the after-due-date follow-up automatically, based on the due dates you’ve already set when creating each invoice.

Combining Reminders with Recurring Invoices

For agencies with retainer clients, reminders become even more useful when paired with Recurring Invoices. When you enable Recurring Invoice under Invoice Options and set a billing schedule and end date, Direct Invoices generate and send a new invoice each cycle, and your reminder settings apply to each of those invoices automatically, without needing to reconfigure them every month.

This means a retainer client on a recurring monthly invoice gets the same before-and-after-due-date reminder treatment every cycle, without you touching the settings again after the initial setup.

Tracking Outstanding Invoices

Reminders reduce manual follow-up, but you still need visibility into which invoices are actually outstanding. The Invoices dashboard shows every invoice’s status:

  • Draft — created but not sent
  • Sent — delivered, awaiting client action
  • Paid — client has indicated payment, pending your verification
  • Hold — under review while you confirm payment
  • Completed — payment verified
  • Overdue — due date passed without payment
  • Cancelled — no longer active

For an agency managing multiple clients, the Overdue status is the one worth checking regularly; it tells you which invoice reminders haven’t resolved and which may need a more direct, personal follow-up. You can review invoices individually or use bulk actions to send reminders to several overdue invoices at once.

Conclusion

For agencies juggling multiple clients, the real cost of manual invoice follow-up is the ongoing attention it takes to track due dates across every client at once. By setting due dates on every invoice and configuring automatic reminders once under Invoice Preferences, Direct Invoices handles the before- and after-due-date follow-up automatically, leaving your team to focus on the invoices that genuinely need a personal touch.

If your agency is still tracking due dates manually, Direct Invoices is a practical way to build reminders into your existing WordPress invoicing workflow. Get started with Direct Invoices and set up automated reminders for your clients today.
