Squirrels.ai
Best for: Companies that want to autonomously follow up with their customers about overdue invoices without hiring additional staff.
Squirrels.ai’s AI AR Collections Specialist sends payment reminders across phone, text, and email, effectively handling customer follow-ups at scale.
Most traditional reminder tools send basic, template-based reminders via a single channel (say, email) and disengage when a customer responds. Someone from the AR collections team has to step in and take over the conversation.
Squirrels.ai doesn’t stop there; it replies to responses while referencing your collections playbook, keeping the context intact. For eg, when a customer responds with a payment-related query, the AI understands the intent, and replies with the exact info needed.
Businesses across industries, such as healthcare, SaaS, legal, or manufacturing, can leverage the AI agent to automate their collections process. You can train it simply by uploading your knowledge base, including company policies, SOPs, escalation rules, and more.
Key features of the platform:
- Automated reminders: Automatically reminds and follows up with accounts with overdue invoices.
- Multi-channel outreach: Sends reminders through voice, text, and email.
- Context-aware conversations: References past conversations while engaging with customers.
- Customizable collections playbooks: Businesses can train the AI by uploading a company-specific collections playbook.
- ERP and accounting integrations: Integrates seamlessly with ERPs and accounting software, such as Nimble Accounting, Zoho, etc.
What makes Squirrels.ai different?
Unlike other tools that simply organize collections tasks, Squirrels.ai is designed to focus on sending collection reminders and following up.
For all your overdue invoices, you can upload the contact information to the platform, and the AI agent will automatically initiate the outreach via email, voice, and text. It follows your sequence and collections playbook when engaging with contacts by phone, text, or email.
The platform captures every conversation and automatically assigns contact status (paid, promised to pay, disputed, etc.) based on their reply.
This makes it highly valuable for businesses that spend considerable time manually contacting customers for pending payments.
When you should consider other tools: Companies that require comprehensive credit risk modeling, financial forecasting, or full order-to-cash management.
Squirrels.ai offers both monthly and annual pricing, with standard credits granted upfront. You can buy additional credits to scale your collections outreach.

Finance teams can quickly get answers to queries about their customers, invoices, balances, aging, and payments. For ease of understanding, Billie can also provide answers in a table or chart.
Biller Genie sends both mailed and printed invoices, reminders, and follow-ups. Thus, it is ideal for businesses that spend excessive amounts of time emailing customers to clear pending invoices.

How to choose the best AI collections software for your business
There are hundreds of AI collections software options. You should carefully consider various factors that should help you choose the right solution. Your comparison should include automation level, communication channels, integration capabilities, and more.
Let’s dig into five important factors you can consider when choosing the best AI collections tool for your business:
1. Level of collections automation
Some tools automate basic payment reminders. Others can independently communicate with customers, respond to questions, and capture payment commitments.
Determine whether you need workflow automation, AI-assisted collections, or autonomous AI agents.
2. Communication channels
Customers respond differently to email, phone calls, and text messages.
If your team frequently calls customers about overdue invoices, consider software that supports AI-powered voice conversations alongside email and SMS.
3. ERP and accounting integrations
Your collections software should work with your existing financial systems.
Look for integrations with QuickBooks, NetSuite, SAP, or your current accounting solution.
Verify whether the integration supports invoice data, customer records, payment statuses, and collections outcomes.
4. Reporting and payment visibility
Effective collections management requires visibility into outstanding balances and customer responses.
Look for software that helps your team track overdue invoices, payment commitments, collections activities, and Days Sales Outstanding (DSO).
5. Implementation and total cost
Evaluate the total cost of ownership, not just the subscription fee.
Consider implementation expenses, integration requirements, communication charges, training, and ongoing administration.
A platform with extensive functionality may not deliver better value if your main objective is automating repetitive collections follow-ups.
