Tools we build

Accounts Receivable AI Agent

 Collect faster. Reply smarter.

The Accounts Receivable Agent is built to streamline and automate repetitive inbox tasks. Around 90% of incoming AR emails ask the same recurring questions, such as:

  • “Can I get a copy of invoice X?”

  • “I’d like to cancel my subscription.”

  • “Can you update my (email) address?”

  • “Can you add a PO number?”

  • “I want to change my credit card or bank account.”

This AI agent automatically processes those requests through integrations with tools like Outlook, Mollie, Stripe, Shopify, Exact Online, Payt, and your internal help center. It pulls relevant data from various sources and generates a ready-to-send draft email.

Lower DSO

Throughout my career at Channable and various ventures, I’ve consistently focused on optimizing financial processes. Whether leading finance teams, building B2B comparison platforms, or managing digital operations, one thing has become clear: manual finance work is holding businesses back.

That’s why I started NexFin AI — to bring smart AI solutions to financial workflows. I help companies automate and improve their financial operations using intelligent tools that eliminate inefficiencies and increase accuracy.

Why You Should Hire an AI Expert for Finance Automation

Finance teams across the world are under increasing pressure: close the books faster, reduce manual errors, and provide insights for strategic decision-making. Yet many departments still spend countless hours on repetitive tasks like invoice matching, payment reminders, and reconciliations.

This is where hiring an AI expert for automation in finance can be a game-changer. By combining artificial intelligence with workflow automation, companies can transform their finance operations from reactive to proactive.

The Case for Finance Automation

According to recent reports, over 60% of finance teams still haven’t implemented AI into their workflows. The main reasons? A lack of internal expertise, unclear ROI, and concerns about data security.

But the teams that have embraced AI are already seeing results:

  • 80–90% of AR emails handled automatically.

  • Month-end close reduced from 10 to 5 days.

  • Error rates in reconciliations cut by more than half.

The benefits are too significant to ignore. Automating repetitive finance processes doesn’t just save time — it directly impacts cash flow, compliance, and employee satisfaction.

What an AI Expert Brings to the Table

Hiring an AI expert means you don’t have to experiment blindly with tools or frameworks. Instead, you get a specialist who understands both finance processes and modern AI workflows.

An AI expert can help you:

  1. Identify the right use cases
    From accounts receivable to month-end close, the first step is mapping the processes that deliver the highest ROI when automated.

  2. Integrate AI with your existing stack
    Whether you use Exact Online, QuickBooks, or Stripe, an expert can connect these tools to AI models and automation platforms like n8n.

  3. Design smart workflows
    Imagine reminders that stop the moment a customer pays, or inbox replies that include the latest invoice and payment status. AI experts design these workflows to reduce DSO and manual effort.

  4. Ensure compliance and security
    Finance data is sensitive. An experienced expert will set up GDPR-compliant processes with EU hosting, encrypted connections, and audit logs.

  5. Upskill your team
    Beyond building workflows, a good AI expert trains your finance team to use and trust the new systems.

Example Use Cases

Here are some automation projects where hiring an AI expert pays off quickly:

  • Accounts Receivable Automation: Smart reminders + AI autoresponder for incoming emails.

  • Month-End Close: Upload PDFs with balances, and let AI draft journal entries directly into your ERP.

  • Data Reconciliation: Automatically match payments with invoices across multiple systems.

  • Dashboards & Reporting: Build real-time dashboards for DSO, cash flow, and AR status without manual exports.

Why Not Just Do It Internally?

Some CFOs assume their teams can experiment with AI on their own. The reality is that finance staff rarely have the time or technical skills for proper implementation. Without guidance, projects stall or remain surface-level experiments.

By hiring an AI expert, you skip the trial-and-error phase and move directly to proven solutions. This saves months of wasted effort and ensures a faster ROI.

Getting Started

If you’re ready to explore finance automation, start small. Pick one process — such as AR reminders — and let an AI expert design a workflow that delivers quick wins. Once your team sees the value, scaling to other processes becomes straightforward.

At Finance AI specialist, we help businesses implement AI-driven finance automation with tools like our accounts receivable AI automation and FinClose for month-end close.

Conclusion

Hiring an AI expert for automation in finance is not just about efficiency. It’s about building a smarter, more resilient finance function that can support growth and strategy. From automating AR to streamlining compliance, the opportunities are endless — and the sooner you start, the sooner you benefit.
