The Challenge:
Manual AR grind throttled cash flow
For Colliers, like many service-based companies, managing accounts receivable can be a frustratingly manual and time-consuming process. Teams tend to generate ad-hoc reports on overdue invoices, and then take the time to craft individualized follow-up notes that must balance the right amount of nudging, pestering and insistence. Customers in turn frequently requested copies of invoices, or full statements of accounts, which AR staff had to compile manually while further delaying the processing of the invoices.
Recent surveys suggest over 80% of businesses chase a customer down from 1-4 times for overdue payment, showing the case for an automated solution. But businesses often struggle with how to best integrate automated workflows into their existing structures.
Given the challenge, Colliers recognized the importance of finding the right invoice processing automation solution to help turn this time-consuming menial task into a cash-collection machine on autopilot.
Automate aging-report workflow:
AR staff spent hours exporting aging lists, isolating 60-day-plus invoices, and hand-writing reminder emails; the new system had to surface overdue items automatically and generate standardized, on-brand outreach in seconds.
Embed friction-less digital payments:
Because collectors relied on an ad-hoc process, only a small fraction of invoices were paid online last year. Colliers needed built-in, secure “pay-now” buttons that could accompany every notice and dramatically boost same-day settlement.
Give customers self-service documents & cut DSO:
Each request for a missing invoice or full Statement of Account triggered a manual scramble, slowly adding to the share of receivables aging past 90 days. The solution had to make it easier for the AR team to pull key documents on demand in order to shorten the cash-collection cycle.
“We were constantly throwing employee hours at the problem, hiring a bigger administrative team, which both was costly and carried significant risk. We had pushed as far as we could with the idea of outsourcing to make up for productive capacity.”

The Solution:
StackDC’s AI Workflow Automation Tool Unity
Unity’s core no-code automation platform and Cash Collector module add-on turned this labor-intensive afterthought into a proactive cash-flow engine, paying for itself in months and compounding returns every billing cycle.
Key Deliverables:
Automated Collections Workflow
Unity’s core document workflow automation system allowed Colliers to transform its AR and invoicing workflow, providing customizable workflows that reduce the time and effort required for creating invoices and following up with clients until cash hits the books.
Preset Dunning Template Ladder
Pre-written emails escalate from polite nudge to legally-framed notice and dispatch automatically by invoice age, balance, and customer tier. This keeps accounts on a transparent schedule, drives increased collections, and frees time for higher value work all while protecting customer relationships.
Embedded Pay-Now Links
Unity’s integration with payment gateways like Stripe allows for payment links to automatically be populated in every notice. Dedicated payment tracking simplifies the cash reconciliation process and cuts any “check is in the mail” manual payment delays.
Analytics and Smart Thresholds
Sortable tables, customizable reports and dashboards easily surface at-risk invoices while presenting the key data finance teams need to forecast cash flow.
IP Protector Module
Colliers also implemented Unity’s Paywall functionality to protect its intellectual property-based product. Now, instead of releasing appraisal reports and then invoicing for payment, customers are notified that a deliverable is ready, but must pay the invoice to access it.
