yeah, you'll need an office 365 subscription, it costs i think 5$ a month, but you can budget your montly income on your phone in an app, or if you want to go the whole nine yards on an entra domain, you can do accounting on excel for the whole company using a shared onedrive

writing a word document on an iphone may sound tedious, but its ok. you wont be able to write an essay, but you can edit and write documents for work it, and outlook is included for those on corporate vpns

so yeah, this also works on android i think, but androids a mess, but on your iphone you can have full access to your windows corporate account hosted on windows server or entra on your phone, great for on the go or on vacations

enjoy
