FAQ
Questions, answered.
What is accounts receivable automation?
Accounts receivable automation handles the work between finishing a job and getting paid: creating invoices, delivering them, tracking payment status, following up on overdue invoices, and showing what you’re owed. PayFlowAI brings these steps together so you spend less time on manual admin.
How does PayFlowAI help with payment follow-ups?
PayFlowAI writes reminder drafts from the invoice details, in a tone that suits each stage from friendly to firm, and you review and send them. On Pro, automated reminders go out on a schedule you set around due dates. Outstanding and overdue invoices stay visible in one place.
Can I create invoices in natural language?
Yes. With Natural Language Invoice Creation you describe the invoice in plain English in the ⌘K command bar, for example, "Invoice Acme for 3 days consulting," and the agent drafts the invoice with line items, tax, and due date for you to review and approve.
Does PayFlowAI support European e-invoicing?
Yes. PayFlowAI supports ZUGFeRD and XRechnung for EU/EEA sellers, built to EN 16931. Requirements vary by country — Germany and Belgium currently have live B2B e-invoicing mandates — so check the rules that apply to your business. See e-invoicing details →
Who is PayFlowAI for?
