How to separate business money from personal money
In a small business, mixing the accounts seems inevitable: the owner pays a supplier with a personal card, takes money from the business account when things get tight at home, and at the end of the month nobody can say whether the business made a profit. Separating the accounts is what lets you know how much the business really earns and how much you can spend without putting it at risk.

Why is mixing them so common?
At the start, the business and the owner are almost the same person. Money comes into one account, goes out of another, and everything seems to work as long as something is left at the end of the month. The problem shows up when things get tight: the business pays the child's school, the household covers the supplier, and the numbers of one get mixed with those of the other.
With mixed accounts, the business may be losing money and the owner only finds out when the cash runs out. The opposite also happens: the business is doing well, but the household is always tight because the owner doesn't know how much can be taken out safely.
What is the first step?
One bank account for the business and another for you, and a simple rule: everything that belongs to the business goes through the business account, even when it is small. Revenue comes in there, suppliers and taxes are paid from there, and the personal card stops paying business expenses.
Money only moves from the business to you through an agreed withdrawal, never by the shortest route. In the first months, it is worth noting every exception that slips past the rule. That is what shows where the accounts still cross.
How much can I take out of the business?
The safest way is to set a fixed monthly amount that the business can pay even in a weak month, instead of withdrawing according to what the household needs. That amount, the owner's salary (pró-labore in Brazil), is your pay for working in the business, and it is what you build your personal budget on.
Profit is taken out after the month closes and the result is known, not before. Part of what is left stays in the business as a cash reserve, for weak months and for growth. The form of each withdrawal and the tax on each one are for your accountant to define; planning makes sure the withdrawal fits both the business's cash and your household budget.
How do I know whether the business really makes a profit?
Money in the account and profit are different things. Profit is what is left from sales after the costs and expenses of the period are paid, and it appears in a report called the income statement (DRE in Brazil). Cash is the money that actually came in and went out, and it appears in the cash flow.
A business can make a profit and run out of cash, and it can have cash while losing money. A business that sells on credit, for example, records the sale today and gets paid months later. Looking at both numbers every month, separate from the household numbers, is what avoids the surprise.
What if the business needs my money?
It happens: a weak month, an investment, an unexpected bill. Putting personal money into the business is not a problem, as long as it is recorded for what it is and does not get lost among the accounts.
Your money that goes into the business needs a record, as a loan or as an increase in your investment in the business. Agree on the form with your accountant. That way, when the business recovers, you know how much it owes you, and the numbers of one do not hide those of the other.
Where BASE comes in
At BASE, your personal life and your business sit on the same platform, separate, each with its own numbers. The business area brings the income statement (DRE), the cash flow statement (DFC) and the cash position, and the platform shows the effect of one on the other: how much to take out, what that does to the cash and what is left for your life.
The business area is included from the Essencial plan, at R$ 149 a month, in which an advisor builds the diagnosis and the plan with you.
