When a customer receives their bill, that email isn’t just a little notification — it’s a crucial chance to make sure they remember to pay their invoice on time. After all, email inboxes tend to get crowded, which means regular reminders get overlooked — and then due dates get missed.
But there’s a simple way to cut through the noise and make sure bills are paid promptly every month: add to calendar links.
With AddEvent, you can easily embed add to calendar links directly into your billing or invoice emails, or add to calendar buttons on your billing website pages. Regardless of what payment provider or email tool you’re using to communicate with your customers, our calendar links integrate smoothly into your existing workflows.
Instead of hoping your email gets opened again in time to pay that bill, make sure the due date ends up somewhere your customer is guaranteed to see it: on their personal calendar.
Depending on how your existing system is set up, AddEvent can easily be integrated.
Our automated add to calendar links work great to provide your customers with an add to calendar link that’s been dynamically personalized for their unique event, such as the due date and time, instructions on how to pay their bill, etc.
And you can install these automated ATC links in just minutes — it’s as simple as adding a short snippet of code to your website, landing page, or email template. And these work across all major calendar platforms, be it Google, Apple, Outlook, Yahoo, etc.
It’s seamless. No coding. No custom development. Just one powerful link your team can drop into any billing communication.
Most people don’t live out of their email inbox — they live by their calendars.
Research shows that 23% of those surveyed schedule everything in their calendar, while only 12% use their inbox to make sure things get done.
So even if they forget the email, the reminder lives on. And when the due date rolls around? They’ll get a notification, just like any other appointment.
This small change can significantly reduce missed payments, late fees, and customer churn — without adding a ton of new work to your tech stack.
One of Australia’s largest customer communications providers used AddEvent to solve a growing issue for their utility client: too many late payments, even with regular email reminders.
By adding calendar links to billing emails, they gave customers a new way to remember due dates. Adoption was instant — and years later, it’s still in place.
As their IT manager shared, “None of our customers have asked us to remove it!”
The reminder isn’t just convenient — it’s effective.
Once you’ve seen how well calendar links work for billing reminders, you’ll find plenty of other opportunities to use them:
If your message involves a specific date and action, calendar links help make it stick.
