A Modern Back Office Tech Stack for Small and Midsize Businesses

For many business owners, the back office just works—until it doesn’t. A payroll run goes sideways, bills pile up, or your bookkeeper sends over a report that raises more questions than answers.

That’s usually when the question comes up: Are we using the right systems?

Your technology stack—the tools powering your accounting, payroll, HR, and benefits—is more than software. It’s the foundation behind your business.

At Tenth Avenue Group, we work with business owners who know their current setup isn’t working but aren’t sure how to fix it. Upgrading systems can feel risky. Even if the software is affordable, there’s time, training, and disruption to consider. But when it’s done right, the payoff is real.

Here’s the back office tech stack we recommend for most small to midsize businesses:

• QuickBooks Online – A cloud-based accounting platform that keeps your books clean and accessible.
• Bill.com – Automate payables and approvals without losing control or visibility.
• Gusto – Payroll, HR, and benefits all in one user-friendly system.
• Guideline – A modern 401(k) platform that integrates seamlessly with Gusto.
• Ramp – A corporate card and spend management platform that helps you control costs, automate accounting, and close the books faster.

These aren’t niche platforms—many growing businesses rely on them every day. They’re trusted, well-supported, and built to scale.

We’ve helped a number of companies modernize their back office, reduce manual work, and get clearer financial visibility. If your current tech stack feels outdated or disconnected, it might be time for a change.

Let’s talk about how the right systems can make your business stronger, simpler, and easier to run.
