Freelance web developer
I've used Xero since 2014 as the accountancy software for my businesses, inluding for Si Novi, my Digital Product Studio based in Manchester. Using it almost daily has allowed me to become familiar with both the user-interface features of the app, plus the API and ways to integrate with Xero.
The Xero API is in constant development and has recently has some useful updates, including the ability to send email invoices to your customers via the API. It's possible to control almost all the invoice and purchasing functions via the API, which can mean businesses can fully integrate their back-office or operations software and processes, generating invoices and bills automatically.
