Before you write
Two things that answer most questions.
The in-app guide
Once you are signed in, the Guide in the sidebar walks through connecting your accounting software, setting up cadences, the AI voice and messaging, payments, and reconciliation. Most how-to questions are answered there.
Your connected books
diol connects to QuickBooks Online and Xero with your permission, reads your invoices and customers, and writes payments and credit notes back so your books stay reconciled. You can disconnect at any time from Settings, which revokes access and removes the stored tokens. The privacy policy and terms cover how that data is handled.
