Internal Controls Checkup: Protecting Your Professional Services Firm

Why Internal Controls Are Important

If you’re a lawyer, dentist, or professional service provider, your skills are the heart of your business. But just as important as your expertise are the systems you use to protect your firm from errors, fraud, and financial risks.

Internal controls aren’t just about following rules—they help you build client trust, ensure your processes are accurate, and keep your business running smoothly. Whether it’s tracking billable hours or protecting sensitive client information, having the right controls in place can make a big difference.

Here’s a simple guide to help professional service firms like yours evaluate and strengthen their internal controls.

Cash Flow: Keeping Your Finances in Check

For professional firms, handling cash and payments is part of everyday business. Without good controls, it’s easy to lose track of where money is going.

Divide Tasks: Don’t let one person handle payments and reconcile accounts. Split these tasks between employees, or check them yourself regularly.

Track Client Payments: Are you keeping a clear record of client retainers and other payments? Mismanaging these funds can damage client trust.

Deposit Daily: Make sure all payments are deposited at the bank daily to reduce the risk of errors or theft.

Use billing software that connects to your accounting system to avoid manual mistakes.

Billable Hours and Fees: Your Revenue Drivers

Accurately tracking the time you spend on client work and the fees you charge is key to your firm’s success.

Use Time Tracking Tools: Make sure everyone in your firm uses reliable software to track their hours. This prevents missed billing opportunities.

Review Regularly: Compare hours worked to hours billed to catch mistakes.

Check Invoices: Double-check invoices for errors like undercharging or duplicates.

Sending detailed invoices to clients not only reduces disputes but also builds trust by showing transparency.

Data Security: Protecting Sensitive Information

Professional firms handle private client data, from legal case files to medical records. If this information isn’t well-protected, it could lead to major problems.

Limit Access: Only give employees access to the files they need for their job.

Back Up Data: Regularly back up client records using secure, encrypted cloud storage.

Check Your Systems: Review your cybersecurity measures often to fix weak spots.

Add two-factor authentication (2FA) to your systems for an extra layer of protection.

Accounts Receivable: Keeping Payments Flowing

Managing accounts receivable means more than just collecting payments—it’s about keeping cash flowing steadily.

Bill Quickly: Send invoices as soon as services are provided. The faster you bill, the faster you get paid.

Remind Clients: Send monthly statements to clients with outstanding balances to keep them informed.

Monitor Aging Reports: Regularly check reports showing overdue payments to see which clients need follow-ups.

Automate payment reminders to reduce the time spent chasing overdue invoices.

Team Accountability: Building a Strong Foundation

Your team plays a big role in your firm’s success, but it’s important to set clear expectations and monitor their work.

Separate Responsibilities: Don’t let one person handle billing, collecting payments, and keeping records. Spread these tasks out.

Train Employees: Make sure your staff understands your firm’s standards and best practices through regular training.

Do Spot Checks: Conduct surprise audits of petty cash or expense reimbursements to catch issues early.

Set up a system where employees can report concerns anonymously. This encourages accountability and transparency.

Client Trust: Your Most Valuable Asset

Trust is the foundation of professional service firms. Having strong internal controls shows your clients that their money, time, and information are in safe hands.

Annual Reviews: Review your internal controls with your team every year. It’s a great way to catch inefficiencies and fix risks before they grow.
