Bookkeeping Best Practices for Small Businesses

As your business grows, guesswork gets expensive. Sloppy books impede informed business decisions, hurt your cash flow, and can wreck your chances in an audit, financing round, or sale. This practical guide breaks down the tools, habits, and checklists you need to build a bookkeeping system that keeps pace with growth and gives you control over your numbers.

Burkland Brief:

• Cash flow problems are the #1 reason small businesses fail. To better manage your cash:
  • Keep business and personal finances separate
  • Automate where possible
  • Reconcile frequently (at least monthly) and close books on time
  • Monitor cash in, cash out, and what’s overdue
  • Maintain proper documentation, including receipts
  • Review and refine
  • Upgrade systems before growth outpaces them

1. Separate Business and Personal Finances

Mixing personal and business spending is one of the most common and damaging mistakes we see, especially in the early stages of a company’s growth. It muddies your financial picture, complicates taxes, and can even expose you to legal liabilities.

Use a dedicated business bank account and credit card. Pay yourself a salary or an owner’s draw, rather than casually pulling from business funds. It may seem like it’s no big deal in initial stages, but it makes you look unprofessional to potential investors, and could jeopardize future funding, audits, and reporting.

2. Automate Where Possible

Manual data entry wastes time, invites errors, and slows down your financial visibility. Automation improves both accuracy and efficiency of your financial processes. Further, your time is valuable, and the nominal cost of automation is well worth the return on your time.

Start with these high-impact automations:

• Use accounting software appropriate for your industry and projected growth: Options include QuickBooks Online, Rillet, Puzzle, Netsuite, or Xero. Avoid the temptation to stick with manual spreadsheets, which are difficult to navigate, prone to errors, and hard to scale as you grow.
• Rules and categorization logic: Most accounting platforms let you build rules (e.g., “All Uber charges = travel expense”) to auto-categorize frequent transactions.
• Bank and credit card feeds: Set up automatic transaction imports into your accounting software. This ensures nothing gets missed and reduces manual entry.
• Payroll sync: Use platforms like Gusto or Rippling that integrate directly with your accounting system to automatically record payroll runs, tax filings, and benefit deductions.
• Recurring invoices and payments: Automate client billing for retainers or subscriptions. Set up autopay for regular vendor bills to avoid late fees and save time.

These tools don’t replace oversight, but they reduce errors and free up your team to focus on strategic operations instead of data entry.

3. Stay Current, Don’t Let Books Pile Up

When your financials are months behind, you’re flying blind on cash, profitability, and runway.

Closing your books monthly (or weekly) helps you make informed operational decisions and catch problems early. It also ensures you’re always ready for tax filings, financing, or investor conversations. Timely books also prevent costly mistakes like overdrafts, missed payments, or forgotten receivables.

The longer you wait, the harder it is to catch up.

4. Reconcile Accounts Regularly

Reconciling your books means checking to verify that what’s recorded matches what actually happened in your bank, credit card, and loan accounts. It’s one of the most important ways to keep your financials accurate and catch small problems before they become big ones.

Here’s what smart reconciliation looks like:

• Reconcile monthly (or more often) without fail. Don’t wait until year-end. A regular monthly close helps you spot errors, fraud, or forgotten transactions early.
• Focus on cash accounts first. Start with your operating bank account and credit cards. These tend to have the greatest impact on cash flow and reporting.
• Match deposits and expenses line-by-line to your bank statements. Look for duplicates, missing items, and unexpected charges.
• Review uncleared transactions. If something’s been sitting unmatched for more than a month or two, it could be a duplicate entry, a wrong amount, or a payment you recorded but never actually made (like a check that was written but never sent).

Common issues reconciliations uncover:

• Duplicate charges or entries
• Canceled subscriptions that are still billing
• Customer payments that weren’t recorded
• Transfers recorded twice, or not at all

If your books are off by even a few hundred dollars every month, that adds up fast and throws off your financial reporting, tax filings, and cash flow projections.

5. Track Accounts Receivable and Payable

It’s not enough to know what you’ve sold or spent. You need to know what’s actually been paid and what’s still owed. Poor management of receivables and payables is a leading cause of cash flow issues, which the data shows is the #1 reason small businesses fail. If you’re not tracking the money in and out, you’re flying blind.

To stay on top of it, build these habits into your monthly process:

Accounts Receivable (AR):

• Establish a replicable process, making sure all parties involved understand their role and expected timelines. Documenting your AR process not only helps with consistency, clarity, and scalability in normal operations, but it is also critical for investor or audit diligence.
• Run an A/R Aging Report every month. Look for overdue invoices and follow up on anything 30+ days past due.
• Set clear payment terms on every invoice (e.g., Net 15, Net 30) and enforce them consistently.
• Send automatic invoice reminders at key intervals—immediately before and after the due date.
• Offer easy payment options (credit card, ACH, etc.) to reduce friction and get paid faster.
• Use tools like Bill, Stripe, or QuickBooks Online to automate invoicing and track collections in real time.

Accounts Payable (A/P):

• Establish a replicable process—like in AR, a process helps provide clarity, scalability, and helps comply with diligence requests. It also reduces fraud risk by separating invoice processing and payment duties.
• Track due dates and payment terms for every vendor bill to avoid late fees and damaged relationships.
• Batch payments once or twice a week instead of paying bills one at a time to streamline approvals and cash planning.
• Use software like Bill or Ramp to manage A/P, route approvals, and automate payments securely.
• Take advantage of early payment discounts if your cash flow allows. It’s free savings.

Keeping a close eye on AR and AP helps you project cash flow more accurately, reduce fraud risk, and make smarter decisions about spending, hiring, and growth.

6. Maintain Proper Documentation

Good bookkeeping requires more than good numbers. You also need the paperwork to back it all up.

Maintain organized, accessible records for every financial transaction: receipts, invoices, contracts, and expense reports. Without this supporting detail, your numbers can fall apart under scrutiny from an auditor, a potential investor, or even the IRS.

Here’s how to build good habits:

• Digitize everything. Use apps like Ramp, Expensify or QuickBooks receipt scanner to snap photos of receipts and upload them in real time.
• Attach documents directly to transactions in your accounting software so there’s a clear paper trail.
• Organize by category and date, don’t rely on random folders or your inbox.
• Store documentation securely in the cloud so it’s accessible when you need it and protected if someone leaves the company.
• Keep it consistent. Every vendor bill, reimbursement, and major contract should be backed up and easy to find.

Good documentation pays off when:

• You’re audited and need to show proof of expenses
• You’re raising capital or going through due diligence
• You’re preparing taxes and want to maximize deductions
• You’re selling the business and need to show clean books

If you don’t have documentation, you don’t really have the numbers.

7. Review Reports Monthly

Set time aside each month to review your core financial statements. This is how you catch problems early, validate your strategy, and make confident decisions based on facts, not gut feelings.

Focus on these three reports:

• Profit & Loss (P&L) Statement: Are your margins holding steady? Are expenses creeping up? Is revenue trending the way you expected?
• Balance Sheet: How much cash do you actually have? Are your receivables growing faster than collections? Is debt creeping up?
• Cash Flow Statement: Are you consistently burning or building cash? What’s driving it? Operations, investing, or financing activity?

What to watch for:

• Spikes or drops in key expense categories
• Growing liabilities that don’t seem to decrease month over month
• Slower sales or widening net losses
• Big swings in cash from one month to the next
• Numbers that don’t make sense or don’t match your expectations

Don’t just skim. Spend 30-60 minutes with your numbers. Make it a habit, and you’ll spot issues before they escalate and opportunities before they slip by.

8. Work with a Professional Bookkeeper

Bookkeeping may seem easy to DIY in the early days. However, getting your books set up correctly from the start will help you ensure your books are accurate and scalable. As your business grows, so does the complexity; more transactions, more accounts, more reporting requirements—all of which are easier to grow into if your books are set up correctly from the start. A professional bookkeeper can recommend the best tech stack for your specific business needs, set up an appropriate chart of accounts, and ensure integrations and system mapping are accurate and working correctly. A professional bookkeeper can also introduce efficient processes and a higher level of accuracy and sophistication to your financial reporting. They spot trends, catch inconsistencies, and ensure your books are ready for scrutiny. An outsourced bookkeeping team can give you even more support as your needs grow, without the cost of a full in-house hire.

If you’re still doing the books yourself, or relying on someone without formal training, it may be time to level up.

Symptom	What It Signals	Suggested Action
You don’t have a handle on AP/AR	Cash flow concerns	Implement and refine processes
You’re still using spreadsheets for core financials	Scalability risk	Migrate to cloud-based accounting software
Owner is still doing the books	Time + risk tradeoff	Hire a bookkeeper or fractional team
You’re guessing about cash flow	Incomplete visibility	Implement cash flow reporting
Reports are late, inconsistent, or inaccurate, or you aren’t sure how to interpret them	Lack of oversight or technical expertise	Bring in controller-level support

9. Prepare for Growth

If your accounting is not set up correctly from the start, you risk failure before you even get off the ground. Accurate financials are critical to drive operational decisions that will ultimately determine the success of your business. It’s worth noting that the financial function must grow as your company grows and adds complexities like contract revenue, multiple entities, international vendors, accrual accounting, GAAP compliance, and investor reporting.

Don’t wait until the cracks start to show. If your month-end close is sloppy, your reports are always late, or your leadership team is spending too much time chasing numbers, it’s time to invest in upgraded systems and financial oversight.

That might mean new software, improved processes, or bringing in a professional bookkeeper to help out. Whatever it takes to stay ahead of growth.
