How to Manage Business Finances as a Non-Accountant Owner

To manage your business finances without being an accountant, set up a few habits and keep them: run business money through its own account, record income and expenses every week, read three numbers every month, set money aside for tax as you earn it, and keep your records for as long as the IRS can ask for them. An accountant or bookkeeper handles the technical work. Your job is to keep the records clean and to look at them regularly enough to act.

This page is about the owner's routine. For the detail behind each habit, see how to open a business bank account, how to manage cash flow, what is a profit and loss statement and how to create a business budget. Sole traders can also read how to manage freelance finances.

Keep business money separate

Run every business sale and purchase through a business account, and pay yourself from it in set amounts. Mixed accounts can make it hard to see what the business earns and slow down every conversation with your accountant.

Record income and expenses every week

Pick one time each week to enter what came in and what went out, and to keep the receipts with each expense. In the US, the IRS says (page last reviewed or updated May 1, 2026): "Good records will help you monitor the progress of your business, prepare your financial statements, identify sources of income, keep track of deductible expenses, keep track of your basis in property, prepare your tax returns, and support items reported on your tax returns."

Read three numbers every month

Once a month, look at:

• Revenue: what you invoiced or sold in the month.
• Gross profit: revenue minus the direct cost of delivering it, and that figure as a share of revenue.
• Cash: what's in the bank, and how many months of your usual spending it covers.

A month that looks profitable can still leave you short of cash if clients pay late, so read profit and cash together.

Set tax aside as you earn

Taxes can be easier to pay when the money is already set aside. In the US, the IRS says (page last reviewed or updated September 25, 2026): "Individuals, including sole proprietors, partners, and S corporation shareholders, generally have to make estimated tax payments if they expect to owe tax of $1,000 or more when their return is filed." Your accountant can tell you how much to put aside and which payment dates apply to you.

Keep records for as long as they can be asked for

In the US, the IRS says (page last reviewed or updated June 30, 2026): "The length of time you should keep a document depends on the action, expense, or event which the document records." It adds: "Generally, you must keep your records that support an item of income, deduction or credit shown on your tax return until the period of limitations for that tax return runs out." Your accountant can tell you which periods apply to you.

Worked example: a monthly check

Sample figures: in March a design studio invoices $18,000.00. Direct costs, such as freelancers and printing, come to $7,200.00, so gross profit is $18,000.00 − $7,200.00 = $10,800.00, which is $10,800.00 ÷ $18,000.00 = 60% of revenue. Overheads are $6,500.00, leaving $10,800.00 − $6,500.00 = $4,300.00 before tax. The studio has $27,400.00 in the bank and spends $13,700.00 in a usual month, so its cash covers $27,400.00 ÷ $13,700.00 = 2 months.

Work with your accountant, not around them

Send your accountant clean records on a schedule, ask them which numbers they'd like you to watch, and bring questions before you make a big purchase, take on debt or hire. Their advice can only be as good as the records you give them.

Where Billed fits

Billed's reporting page says: "See how profitable your business is with Income vs Expense report." It also says: "See your partially paid, past due and paid invoices in a glance with Invoice reports." On the spending side, Billed's expense tracking page says: "An expense in Billed records who you paid, when, how much and which category it belongs to, with the receipt attached to the same entry."

Mistakes to avoid

• Paying business costs from a personal account
• Leaving bookkeeping until tax time
• Watching profit but not cash
• Spending the money you'll owe in tax
• Throwing away records before the IRS's periods have run out

When this guide isn't for you

If your business has investors, inventory or several entities, you'll need more than these habits. Ask an accountant to set up the reporting you need.
