The Business screen
Where you manage your expense types and export a tax year.
Open More and tap Business. This is the management side of business spending; to browse the expenses themselves, use the Business pill in the peek on your Budget screen instead.
EXPENSE TYPES lists your business categories as pills, things like Meals, Travel and Software. Tap one to rename it or change its color, or tap + Add type at the end of the row to make a new one, which needs a name and a color and can take an emoji.
Under the export section, pick a tax year. You can choose the current year or either of the two before it, and the current one is already selected.
Then tap Export {year} expenses. Carlo builds a spreadsheet of every business expense in that year, with the date, amount, type, payee and note, and hands it to your share sheet so you can mail it to yourself or send it straight to whoever does your taxes.
A year with nothing in it cannot be exported. Its button reads No {year} expenses and stays inactive, so pick another year.
