You may want to do some bookkeeping jobs yourself and get an expert to help with others. Maybe you’re still figuring out double entry bookkeeping, or you’re nervous about payroll mistakes, or you simply hate chasing unpaid invoices. That’s normal many business owners handle the parts they feel comfortable with and outsource the rest.
At first, DIY bookkeeping can feel manageable. A few receipts, a couple of invoices, some quick entries in your accounting software it doesn’t seem too hard. But as your business grows, so does the complexity. Suddenly, those “simple tasks” eat up hours of your week, and one small mistake could lead to penalties or missed tax deductions.
What Business Owners Often Handle Themselves
Most small business owners start out doing their own bookkeeping, and that makes sense. In the early days, the volume of transactions is low, and the stakes don’t feel as high. A spreadsheet and a few apps can get the job done. Here are the common tasks that owners usually keep on their own plate:
- Entering expenses into accounting software: Simple purchases like office supplies or fuel are easy to log if there aren’t too many transactions.
- Sending basic invoices: If you only invoice a few clients each month, it feels manageable. But once payments pile up, tracking who’s late becomes a chore.
- Tracking receipts in a folder or app: A quick photo of a receipt works fine until hundreds of them stack up and you can’t find what you need at tax time.
- Watching bank balances: Checking your account daily gives peace of mind, but it doesn’t replace knowing whether your books actually match.
Where DIY Bookkeeping Breaks Down
As the business grows, the simple system that once worked starts showing cracks. More clients, more staff, and more transactions quickly turn bookkeeping into a specialized job. These are the areas where most owners hit roadblocks:
- Payroll: Taxes and filing requirements differ by state and change often. Missing a deadline or underpaying, even by accident, can lead to penalties.
- Reconciliation: When you’re handling a handful of transactions, matching books to bank statements feels easy. But with hundreds of entries, small errors snowball into major headaches.
- Expense categorization: Mislabeling a business lunch as “meals” instead of “client entertainment” might seem harmless but multiplied over a year, these errors can mean missed deductions.
- Tax prep: Piling everything up for year end means rushed entries, forgotten receipts, and more stress than necessary.
The Hidden Costs of Doing It All Yourself
The biggest danger of DIY bookkeeping isn’t just making a mistake it’s not realizing how much it’s costing you in other areas. What looks like saving money on professional help often creates hidden losses:
- Lost time – Those evenings spent reconciling accounts are hours you could use for sales, training staff, or just relaxing with your family.
- Missed deductions – Without expert knowledge, many small but valuable write offs slip through the cracks. Over time, that can add up to thousands in overpaid taxes.
Stress and second-guessing – The constant worry of “Did I do this right?” takes a toll. And if the IRS comes knocking, being on your own makes it even worse..

Finding the Right Balance
The good news is, it doesn’t have to be all or nothing. You don’t need to outsource everything, but you also don’t have to shoulder it alone. Many business owners find a hybrid system works best:
- You handle: receipts, invoices, and day to day expense logging the tasks that keep you close to your numbers.
- Your bookkeeper handles: payroll, reconciliations, tax filings, and reporting work that requires precision and expertise.
- Together, you review: monthly or quarterly reports to stay aligned on goals and spot issues before they grow.
