Send the Right Reminder at the Right Moment

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.

Reach Customers Through Multiple Channels

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.

Send Professional Email Reminders

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.

Include Secure Payment Links

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.

Save Time Across Invoice Management

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.

Built for Small and Growing Businesses

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.

Why Businesses Choose Collie

Businesses choose Collie because it automates a process that is often repetitive, time consuming and difficult to manage consistently.

The platform combines professional communication, secure payment links and real-time visibility without requiring complex reminder schedules or a large technical setup.

Get Paid Faster With Less Manual Work

Late payments should not require hours of emails, phone calls and manual tracking.

Collie helps businesses automate payment reminders, simplify online payments and keep communication professional while giving finance teams more time for the work that supports the wider business.

Upload Your Invoices

Upload an Excel or CSV file containing the relevant invoice and customer information.

Collie checks the data before reminders begin, helping identify missing details that could prevent successful communication.

Start the Automated Reminder Journey

Once the file is ready, Collie begins sending reminders through the channels included in the journey.

The platform adjusts the sequence according to customer response rather than requiring the team to build every reminder workflow manually.

Guide Customers to Payment

Email and SMS messages can include secure payment links, allowing customers to pay online through the Mollie payment environment.

This shortens the path from reminder to payment and reduces the need for additional follow-ups.

Track Progress in Real Time

The dashboard shows which invoices have been paid and which remain open.

Teams can review reminder activity and payment status from one place instead of maintaining separate spreadsheets.

Frequently asked questions

Have more questions? Our experts can help.

Use SMS for Timely Notifications

SMS gives businesses a direct way to send timely notifications about upcoming or overdue payments, particularly when customers may not see an email immediately.

Collie sends clear and friendly SMS reminders that explain the open invoice and provide a simple link to the available payment journey.

Add Natural Voice Reminders

Some customers respond more effectively to a phone call than to a written message, but making reminder calls manually can require a significant amount of staff time.

Collie can place automated voice reminders using a natural and professional voice, helping businesses add phone calls to the reminder process without assigning an employee to every call.

Use Recognizable Local Numbers

Customers are more likely to answer a call when the number appears familiar and relevant to their location.

Collie uses local phone numbers for automated reminder calls, helping the communication feel more trustworthy and reducing the chance that the call is dismissed as unrelated or suspicious.

Keep Every Message Professional

Payment reminders need to be clear enough to encourage action without damaging client relationships. Messages that feel aggressive, inconsistent or disconnected from the brand can create unnecessary tension.

Collie helps businesses maintain professionalism by using structured reminder journeys, recognizable branding and respectful language across email, SMS and voice.

Make Paying Easier

The payment process should not become another obstacle after the customer has decided to act. A complicated journey can turn a timely response into another missed payment.

By including direct payment links within reminder messages, Collie helps customers complete payments online without searching for additional information or contacting the finance team.

Process Payments Through Mollie

Collie uses Mollie to process online payments, giving businesses a familiar and established payment environment.

Companies can connect an existing Mollie account or create a new one during sign-up, allowing the payment journey to be set up as part of the onboarding process.
