Late payments do more than delay revenue. They create extra administration, weaken cash flow visibility and force finance teams to spend time on follow-ups that could be handled more efficiently.
Collie payment reminder software helps businesses automate that process from invoice upload to completed payment. Instead of relying on spreadsheets, repeated emails and manual phone calls, teams can manage reminders, payment links and payment tracking from one platform.
Collie is the self-service payment reminder solution from Collectmaxx, created for businesses that want a professional way to reduce overdue payments without building complicated workflows.
The platform combines more than 20 years of payment reminder experience with AI-supported automation, guiding each open invoice through voice, SMS and email reminders.
Following up on overdue invoices often involves checking due dates, reviewing customer data, writing messages and recording responses manually. As invoice volumes grow, this work becomes harder to manage consistently.
Collie automates much of that routine activity, helping finance teams spend less time on repetitive communication and more time maintaining accurate records and supporting day-to-day business operations.
Getting started is designed to be straightforward. Businesses can upload outstanding invoices through an Excel or CSV file instead of completing a lengthy technical implementation.
Before any payment reminder is sent, Collie checks the uploaded information for missing details. This helps reduce errors and ensures the platform has the customer data needed to begin the reminder process.

Many automated payment reminder tools require users to define every trigger, delay and escalation rule before a campaign can begin. That setup can be time consuming, especially for smaller finance teams.
Collie removes much of that complexity by creating the reminder sequence automatically using Collectmaxx payment reminder experience and AI technology.
Different customers respond to different types of communication. A quick reminder by email may be enough for one person, while another may respond more quickly to SMS or a professional reminder call.
Collie adjusts the reminder journey based on how the customer responds, helping businesses use the right channel at the right moment without asking employees to manage every decision manually.
Relying on a single communication channel can make payment collection less effective, especially when customers overlook email or do not recognize an unfamiliar message.
Collie uses voice, SMS and email within the same automated reminder workflow, giving businesses more opportunities to reach customers while keeping communication professional and consistent.
Email remains an important part of invoice management because it gives businesses enough space to explain the open invoice clearly and provide a direct route to payment.
Collie sends professional reminders on behalf of the business, using the company name, logo and recognizable sender details so customers understand who the message relates to and why they are receiving it.
Every reminder should make the next step easy. When customers need to search through previous messages, locate bank details or request another invoice copy, payment is more likely to be delayed.
Collie can include a secure payment link in email and SMS reminders, allowing customers to move from the message to online payment in just a few clicks.
Invoice follow-ups often involve many small tasks, including reviewing records, writing messages, placing calls and confirming payment status.
Collie brings these activities into one automated process, helping finance teams save time and manage more invoices without increasing manual effort at the same rate.
AI-powered outreach drives higher payment rates.
Accelerated payments ease financial strain.
Small businesses often feel the impact of late payments quickly, while growing teams face a rising volume of invoices and follow-ups.
Collie provides a self-service way to automate payment reminders without requiring a large accounts receivable team or a complicated implementation project.
Collie is built by Collectmaxx, a company with more than 20 years of experience in payment reminders.
That experience is used to shape the reminder sequence, communication channels and payment journey inside the platform, giving businesses a self-service tool built around established payment knowledge.
Collie combines automated payment reminders, branded emails, SMS reminders, natural voice calls, secure payment links and real-time tracking in one self-service platform.
It also supports invoice uploads through Excel or CSV, checks files for missing information and uses AI-supported logic to guide the reminder sequence.
