Log a business expense
Business spending is logged like anything else but kept out of your personal budget.
Log it the way you log anything, by voice or by hand. By voice you can just say so: "business expense", "work expense", "for work", "reimbursable", "company card" or "client dinner" all route the entry to the right business type on their own.
By hand, scroll to BUSINESS EXPENSE in the category picker and choose the type that fits, like Meals, Travel or Software. To move something you already logged, open it and tap Category: picking a business type saves immediately, with no Save button to look for.
From then on it stays out of your way. A business expense never counts against your monthly coins, your daily allowance, or the daily and weekly totals in your Journal, because those figures are what you spent personally. It still appears in your Journal on the day it happened, grouped below your personal transactions and marked with a briefcase, since it is part of your record even though it is not part of your budget.
To see only business spending, open the peek on the Budget screen and tap the Business pill next to Personal. Business is tracked month by month, so that pill appears with your month coins and not your year ones.
