Software is supposed to make reconciliation automatic.

Most of the time, it does.

But “most of the time” is exactly the gap we get paid to close.

We asked our senior accountant what habits help him deliver consistent work. His answer wasn’t a new piece of software.

“One thing I always try to do is compare information across different platforms and make sure everything is consistent. I compare the bank activity with QuickBooks and Bill.com to make sure the systems are communicating correctly and the information matches.”

Three systems. Cross-checked by a person, not just trusted to sync correctly on their own.

Our newer team member’s habits look almost the opposite and somehow land in the same place.

“I print a lot. I print statements, documentation, emails. I keep tabs by hand. You use a notepad, write down what you see in the moment, so you can come back to it.”

Different generation. Different method. Same underlying instinct:

Don’t just trust that everything lines up. Check.

Here’s what that actually catches:

• A sync error between Bill.com and QuickBooks that would otherwise sit unnoticed for weeks
• A transaction that posted twice, or not at all, because two systems disagreed quietly
• A detail that would have been easy to forget by month-end, but wasn’t, because someone wrote it down the moment they saw it

Software failures are rarely dramatic. They’re small, quiet, and easy to miss which is exactly why they need a human cross-check, not just a dashboard that assumes everything’s fine.

Automation handles the routine. People catch the exception.

So the question is: does anyone on your team actually check whether your systems agree with each other, or does everyone just assume they do?
