Summary: With Sage 100 overdue invoice automation, AR teams can eliminate manual follow-up, reduce Days Sales Outstanding, improve cash flow, and free up staff to focus on higher-value work.
This should sound familiar: you send a batch of invoices. Most are paid on time, but a few aren’t, and one is only partially paid. Now your AR department has to track down which invoices are overdue and manually draft reminder emails one by one. For businesses sending dozens or hundreds of invoices a month, this isn’t just a tedious time-waster. It causes real cash-flow problems.
The good news is that Sage 100 can be set up to automate your invoice reminders, so the right customers get the right nudge at the right time, without anyone on your team having to think about it.
How to Set Up Overdue Invoice Automation in Sage 100
The goal is to get Sage 100 to handle invoice follow-up for you. Here’s what that looks like in practice:
- Your system scans Sage 100 continuously for overdue invoices.
- When it finds one, it alerts the appropriate staff members by email, instant message, or text. Your choice.
- It automatically generates a reminder email with the relevant invoice details and a copy of the invoice attached.
- It sends that email to the correct client contact.
- It continues sending reminders on a schedule you define until the invoice is paid.
- Optionally, it can place overdue customers on a credit hold until their balance is cleared.
Why Sage 100 Overdue Invoice Automation Helps You Get Paid Faster
It’s easy to see how automation saves time. But if you look a little deeper, you’ll see how it also helps you collect faster. The key is its effect on your DSO.
What is DSO?
DSO, or Days Sales Outstanding, is a metric that measures how long it takes you to collect payment after making a credit sale. A low DSO (roughly 30–45 days) indicates healthy collections; a high DSO (60+ days) points to slower payments and a greater risk of bad debt. Credit insurance company Atradius describes high DSO as “a red flag for financial pressure” that “can drive up borrowing costs, limit strategic investment, and strain supplier relationships.”
Keeping your DSO low isn’t just smart. It’s critical.
How to Lower Your DSO
Late payments are the primary driver of a high DSO, so the most direct way to lower it is to collect late payments faster. This means sending reminders sooner and more consistently.
Here’s how that plays out:
- Your team receives overdue invoice alerts immediately, rather than waiting days or weeks for someone to run a report.
- Your Sage 100 system automatically drafts and sends payment reminders, rather than requiring your AR staff to carve time out of a busy week.
- Follow-up reminders go out on schedule, without anyone having to remember to send them.
As a result of those reminders, most of your customers will pay their overdue invoices faster.
How to Add Invoice Automation to Sage 100
Sage 100 overdue invoice automation isn’t built in, but you can get it with Sage Alerts & Workflow.
What Is Sage Alerts & Workflow?
Sage Alerts & Workflow monitors your Sage 100 data and triggers automated notifications and workflows based on conditions you define, like an invoice crossing its due date.
Because it’s an add-on for Sage 100, it has a low additional cost. Before committing, it’s worth running a simple estimate to calculate your return on investment (ROI).
How to Calculate Your ROI
Ask your AR person to track the time they spend identifying overdue invoices and writing reminders for one month. Then multiply that by their fully loaded rate (salary, benefits, payroll taxes, PTO, and other overhead).
Sage Alerts & Workflow typically costs around $200/month for comprehensive Sage 100 monitoring and workflows for unlimited users. If your AR person’s fully loaded time on invoice reminders alone exceeds that, the math works in your favor.

More Than Invoice Reminders
Sage Alerts & Workflow covers more than overdue invoices. A few examples of what else it can do:
- Inventory monitoring. When a shipment can’t be filled or is back-ordered, Sage Alerts & Workflow can automatically notify your warehouse staff and account managers.
- Sales activity notifications. If a customer hasn’t placed an order in an unusually long time, the salesperson or sales manager receives an automatic alert.
Sage Alerts & Workflow can monitor virtually any data point in your Sage 100 system and trigger the appropriate notification or workflow in response. Curious to learn more?
