If you pay someone to keep your books and still cannot answer simple financial questions about your business, you’re reading the right article. These ten bookkeeping best practices give you a litmus test you can hold up against the service you hire or the one you already use. Get this wrong, and you file a tax return built on shaky numbers and incorrect financial records. Many accounting and bookkeeping firms’ practices would fail this test. We see it time and time again when we perform a Diagnostic Review. 

 

What “Best” Means Before You Judge Any Bookkeeper

Most owners judge a bookkeeping service by one thing: do the reports arrive on time for taxes? That tells you nothing about whether the numbers inside them are right.

Here is the standard I use. A best-in-class bookkeeping service:

• Matches every bank, loan, and credit card balance to the statement, in real time.
• Builds your books on your actual entity type and IRS filing basis.
• Records real transactions as they hit the account instead of forcing journal entries.
• Puts a human eye on every transaction.
• Leaves you in control of your own QuickBooks file.

This article is not for every owner. Some owners knowingly buy the good enough version to save money, and that is a legitimate call to make with your eyes open. I only care that you make it on purpose instead of by accident.

Bookkeeping Best Practice 1: Give Equal Weight to Your Balance Sheet

Almost every owner I meet watches the profit and loss statement and never opens the balance sheet. I understand why. Revenue and expenses feel like the fun stuff, and the balance sheet feels like boring paperwork.

That habit hides the numbers that decide what you owe and what you own. Your balance sheet holds your accounts receivable, your loan and debt balances, and the fixed assets you depreciate. Every bank, loan, and credit card balance on it must match the statement perfectly. When those balances drift, your numbers are wrong, and you cannot file an accurate return.

A law firm came to us after ignoring its balance sheet for about three years. Our diagnostic review turned up several bank and credit card accounts that the firm had stopped using, still sitting open on the balance sheet. Someone needed to close those accounts and record them correctly. We also found several bank, loan, and credit card balances that did not match the statements. Their CPA had been smoothing it all over each year with adjusting journal entries.

The firm agreed to fix the current year and then chose not to pay for three years of proper cleanup. They had the CPA sweep the prior years with journal entries instead. I told the owner plainly that those entries would not do everything a real balance sheet reconciliation does. He picked that road anyway, and that is the fork between best in class and good enough.

Your takeaway: open your balance sheet and compare three balances to your latest statements. If any of them disagree, you have a problem worth a phone call.

Bookkeeping Best Practice 2: Know Your Entity Type and Filing Basis Before Anything Else

Bad books are usually not a math problem. They are a foundation problem.

Your books have to sit on two facts: your entity type and your filing basis. Entity type means LLC, S-Corp, C-Corp, or sole proprietor. Filing basis means whether you file cash or accrual with the IRS. Each one records income and expenses differently, and at different times.

We recently picked up a business that a prior bookkeeper had been serving on an accrual basis. That business files on a cash basis as an LLC. Everything downstream of that mistake was wrong, no matter how neat it looked.

Entity type and filing basis are the first two questions we ask during interviewing. We ask them again at onboarding. Nobody double-checks a question they think they already answered, and that is exactly why we do.

Your takeaway: ask your bookkeeper today which entity type and filing basis your books use. If the answer takes more than a few seconds, keep pulling that thread. Additionally, go check what QuickBooks has you marked as in its’ system.

Bookkeeping Best Practice 3: Very few or No Year-End Journal Entries

Some firms ignore your books all year and then book everything by journal entry to 12/31. That is lazy accounting in my opinion, and I will stand behind it. It is box checking, not accounting.

Most owners never hear the real cost, because it does not show up on the tax return. It shows up in your reporting. Once a year, you hold a pile of catch-up entries; your month-over-month, quarter-over-quarter, and year-over-year comparisons stop meaning anything. The data holds errors, and it will not even compare to a clean year.

You lose the most useful thing bookkeeping gives you: trends you can trust when you make a decision. A tax return tells you what happened. Clean comparison reporting tells you what to do next.

Your takeaway: pull a month-over-month comparison report. If the last month of your year looks nothing like the other eleven, you know what happened.

Bookkeeping Best Practice 4: Never Automate Your Bookkeeping

Most advice you read says to automate everything you can and buy back your time. My answer is the opposite, and I will explain why.

QuickBooks automations and bank rules are never 100% accurate. The software’s AI does not know your spending and revenue patterns the way you do. The people who set up the rules are imperfect too, so there is always an exception the rule gets wrong. One bad rule repeats itself quietly, hundreds of times, until someone looks.

In ten years, I have never once seen fully automated books done correctly. Not once. A human eye on every transaction is the only quality control that works.

AI software will keep improving, and the core problem stays. Software still makes assumptions about your business that it cannot verify. Better guessing is still guessing regardless if its a human who does not understand accounting or a its a robot.

Your takeaway: ask whether anyone reviews each transaction, or whether rules do the sorting. The answer tells you what you are buying.

Bookkeeping Best Practice 5: You hold the Primary Admin seat in your QuickBooks file

Owners rarely think about who holds the Primary Admin seat until the day they want to leave a firm. Then it matters a lot.

The Primary Admin seat controls who gets into your QuickBooks file. It can grant access and revoke access, including yours. (User roles and access rights, 2026) Your CPA, tax attorney, bookkeeper, or assistant should never hold a seat more powerful than the one you hold.

CPA and tax firms often keep that seat rather than hand it to the owner. That gives the firm every bit of leverage in the relationship. It also makes the day you want to fire them awkward and slow.

My position has no exceptions. You stay Primary Admin, because it is your business and your data.

Your takeaway: log in and check the Primary Admin name on your file this week. If it is not you, ask for the transfer in writing.

Five More Bookkeeping Best Practices Worth Checking

The remaining five are shorter, and they still separate careful work from sloppy work.

1. Capture true cash basis data as it hits the bank, loan, or credit card account. Do not build the books out of journal entries.
2. Stay current. The farther you get from a transaction, the harder it is to remember what it was for, and the longer a bad habit runs.
3. Use the right level of detail. Too granular buries you. Too vague dumps every marketing expense into one bucket, so you cannot see ROI or change anything.
4. Use what QuickBooks Online already includes before adding outside apps. QBO covers tools owners often buy twice, such as project tracking and merchant processing, and extra apps bring sync problems. (QuickBooks Online Sync Conflicts, 2025)
5. Document fixed assets and attach statements. Log large purchases and fixed asset receipts so you can depreciate them properly and walk into tax season clean.

Your takeaway: score your current service on all ten. Three or more misses means you are paying for reports, not for accurate books.

Frequently Asked Questions

What should a bookkeeper ask me before they start working on my books?

Your entity type and your filing basis. Those are the first two questions we ask during interviewing, and we ask them again at onboarding. A bookkeeper who never asks whether you file on a cash or accrual basis is guessing at your foundation.

Is it okay for my accountant to catch up my books with year-end journal entries?

It checks a box, and it costs you your reporting. Entries booked to 12/31 make your month-over-month and year-over-year comparisons unreliable, because the data holds errors and will not compare to a clean year. You end up with a tax number and no trends you can trust.

Should my bookkeeper use QuickBooks automations and bank rules?

No. Automations and bank rules are never 100% accurate because the software does not know your patterns, and the person writing the rule can miss an exception. In ten years, I have never seen fully automated books done correctly.

Who should be the Primary Admin on my QuickBooks Online account?

You should, with no exceptions. That seat can grant and revoke everyone else’s access, including yours. When your CPA or bookkeeper holds it, they hold the leverage on the day you decide to leave.

Why does my balance sheet matter if my profit and loss looks fine?

Your balance sheet carries what customers owe you, what you owe on loans and credit cards, and the fixed assets you depreciate. Every one of those balances has to match the statement in real time. A clean P&L sitting on a broken balance sheet still gives you an inaccurate tax return.

The Bottom Line

Use these ten bookkeeping best practices as a litmus test for the service you are hiring or already paying. Reports arriving on time are not the standard. Accurate balances, the right foundation, human review, and your name on the Primary Admin seat are the standard.
