One checking account, one card, and both the business and the household run through them. It is how a great many sole proprietorships start, and it is not a disaster for the financial statements; it is a sorting job. The accounting idea that makes it work is the owner draw.
The owner draw
Money that leaves the business for the owner’s own use is a draw. It is not an expense of the business, so it does not reduce profit. It lives on the Balance Sheet, in equity, as money taken out. The grocery run, the car payment on the family car, the transfer to the personal savings account: all draws. Money the owner puts in from personal funds is the reverse, a contribution, and it is not revenue.
Once personal lines are marked as draws, the Profit and Loss that remains is the business’s, even though the account was shared. That is the whole trick.
Sorting a shared account
- Obvious personal payees: the grocery store, the streaming service, the kids’ school. Mark the payee once and every transaction with that payee follows.
- Obvious business payees: suppliers, software, the trade insurance. Category by payee again.
- Mixed payees: the gas station, the big-box store, the phone bill. Decide a rule and apply it consistently. A phone used mostly for the business can be treated as a business expense with a personal portion drawn out, or the other way round; the preparer will tell you which they prefer. The thing not to do is decide differently each month.
- Transfers to personal accounts: always draws.
What it looks like on the statements
The Profit and Loss shows only business revenue and expenses. The Balance Sheet shows the account balances as they really are, and in equity, one line for owner draws and one for contributions. A reader sees immediately how much the owner took out of the business during the year, which is a number worth knowing in its own right: see why the bank balance is not the profit.
How Rekonix Lite handles it
Every transaction gets a first category, and anything that looks personal is offered as an owner draw. You confirm or change categories by payee, so a year of grocery runs is one decision. Transfers to your personal accounts are recognized as money leaving the business. The result is a business Profit and Loss from a shared account, with the draws where they belong.
Next year
Open a business account and a business card and move everything you can onto them. It does not change the accounting, but it turns next year’s sorting job into almost nothing, keeps the business’s cash visible at a glance, and is what any lender, preparer or buyer expects to see. The year you have now is still recoverable; the next one can simply be clean.
