Accounts Payable And Expense Best Practices

Welcome to The Profit Ledger — your go-to spot for smart bookkeeping tips, tutorials, and tools for small business success. Whether you’re a solopreneur or scaling your team, we help you take control of your finances with confidence.

Managing your bills and expenses may not be the flashiest part of running a business — but it’s one of the most important. A strong accounts payable (AP) and expense management process helps you:

  • Protect your cash flow
  • Build trust with vendors
  • Stay audit-ready
  • Avoid duplicate or fraudulent payments

Let’s break down some simple, effective best practices that every small business should follow.


🔹 1. Separate Business and Personal Expenses

If you’re still running everything through one credit card or checking account, it’s time to fix that. Mixing personal and business expenses is a recipe for tax headaches, inaccurate reports, and missed deductions.

✅ Best Practice: Open a dedicated business bank account and credit card. Run everything business-related through them.


🔹 2. Create a Centralized AP Process

Don’t rely on memory or scattered emails to track your bills. A standardized AP workflow reduces errors and keeps things moving — even if you’re wearing all the hats.

✅ Best Practice: Use a single system (like QuickBooks, Xero, or even a shared Google Drive + spreadsheet) to track:

  • Vendor names
  • Invoice numbers and due dates
  • Payment status
  • Approval notes

🔹 3. Require Documentation for Every Expense

No receipt, no reimbursement. That should be your motto — whether you’re handling expenses yourself or managing a team.

✅ Best Practice:

  • Save digital copies of all receipts (apps like Dext, Expensify, or even a Dropbox folder work well).
  • Tie each expense to a category in your chart of accounts.
  • Match each receipt to a vendor bill or credit card charge.

🔹 4. Use a Consistent Approval Process

Approvals shouldn’t live in text messages or your memory. Having a simple, written process keeps things transparent and defensible.

✅ Best Practice:

  • Create a 1-step or 2-step approval rule (e.g., “All expenses over $500 require approval from the owner”).
  • Use digital tools (like email chains, comments in spreadsheets, or expense management apps) to leave an audit trail.

🔹 5. Schedule Payments Strategically

Paying bills immediately isn’t always the best strategy. If your vendor terms allow Net 30, use that time to manage cash flow wisely.

✅ Best Practice:

  • Review payment terms for each vendor
  • Set reminders for due dates
  • Batch pay bills weekly or bi-weekly
  • Prioritize bills that avoid late fees, affect operations, or offer early payment discounts

🔹 6. Track Recurring Expenses Closely

Recurring charges like software subscriptions or utilities can add up — and sometimes stick around long after you’ve stopped using them.

✅ Best Practice:

  • Review auto-pay accounts quarterly
  • Cancel unused services
  • Record recurring charges as monthly accruals in your books

🔹 7. Reconcile Regularly

Reconciling your AP ledger with your bank and credit card statements catches errors, prevents duplicate payments, and ensures your books are accurate.

✅ Best Practice:

  • Reconcile credit cards monthly
  • Reconcile bank accounts at least monthly
  • Compare vendor statements to your internal records quarterly

🔹 8. Digitize and Automate Where Possible

Manual processes work until they don’t. As your business grows, automation can save time and reduce costly mistakes.

✅ Best Practice:

  • Use accounting software with AP and expense modules
  • Set up bank feeds to auto-import transactions
  • Explore tools like Bill.com, Melio, or Expensify to automate approvals, payments, and reimbursements

🔹 9. Review AP Aging and Expense Reports Regularly

Your AP Aging Report shows what you owe and when. Your expense report shows where your money is going. Reviewing both regularly helps you make better decisions.

✅ Best Practice:

  • Review AP aging weekly to avoid missed payments
  • Review monthly expenses by category to spot overspending or trends

🔹 10. Set Expense Policies (Even if It’s Just You)

Even solo business owners need policies. Set clear rules around:

  • What can be expensed
  • When reimbursements are submitted
  • Approval thresholds

✅ Best Practice: Write a simple 1-page expense policy. It’ll come in handy as your business grows.
