Bookkeeping Basics for Small Businesses

Are you ready to dive into the wonderful world of bookkeeping for small business owners? Buckle up, because it’s going to be a wild ride.

Keep paperwork for asset purchases

Remember that time you impulsively bought a giant espresso machine for your cozy café and didn’t save the receipt? Bad move.

Assets like equipment, real estate, and vehicles are big investments. Allways keep the paperwork and submit digital copies to your GrowthLab bookkeeper. Future-you will be very grateful.


Give your bookkeeper read-only access

Think of this like giving your bookkeeper a spare key so they can tidy up without interrupting you. With read-only access to your financial accounts, they can pull invoices and transactions directly.  And yes… they might see that late-night inflatable unicorn pool float purchase. Don’t worry, it’s a judgment-free zone.

And let’s not forget an accounting rule as old as time: debits should always equal credits. In bookkeeping, this means that every transaction needs to have an equal and opposite reaction. It’s like Newton’s Third Law but with less physics and more spreadsheets. But don’t worry, we’ll take care of this part. 


Categorize transactions correctly for
tax purposes

Did you know that cat food isn’t a legitimate business expense unless you own a cat cafe (Honestly, that would be awesome). But seriously, tax season is no joke, and categorizing your transactions can save you from potential IRS woes. Plus, it’s also a chance for you to get creative with your business acumen. After all, who says buying donuts for the office isn’t a marketing expense? (definitely not the marketing team)!

What to Record in your Books as a Small Business:

1. Keep track of what the purchase was.

Record what you spent money on so you understand where your cash is actually going. (Maybe skip the frivolous online shopping for now).

2. Keep track of where you purchased it from.

Don’t be ashamed to admit it – sometimes, you might forget where you bought something from (we won’t tell anyone). But when it comes to tracking your business expenses, it’s important to remember the vendor or store you made the purchase from. Trust us, it’ll save you from some awkward emails in the future.


3.  How much did it cost?

Okay, we know that keeping track of expenses isn’t everyone’s favorite hobby, but it’s necessary if you want to keep your eyes on the prize– earning more money. Knowing how much you spend on each purchase will help you track your spending against your budget, and help you stay on target with your financial goal.


4. When was the purchase made?

You might not be a time traveler, but it’s important to record the date and time of your business purchases. This information will come in handy when you need to track your monthly expenses or determine your tax reductions.


5. What category does it land on?

Keep your bookkeeping organized by categorizing each purchase. It might seem tedious, but it’ll make your accountant and future self thank you. Plus, when you come across that one mysterious receipt from last year, you’ll know exactly what category it belongs to (spoiler alert: it’s probably office supplies).

And there ya have it– five simple steps to keep your books in order. Have fun spending…, we mean, recording!
