Numbers that matter to you
Invoicing, payment reminders, DSO tracking, and cash flow forecasting, automated, so you can focus on your work.
3 overdue invoices have no recent reminder.
Consider sending a follow-up to reduce further delay.
Built on infrastructure you already trust
Sound familiar?
Your clients receive the invoice but payment is weeks late. Every day outstanding is cash you can't use.
Reminder emails, awkward follow-up calls, spreadsheets tracking who owes what. There has to be a better way.
Know exactly how much cash is coming in this week, this month, this quarter, instead of guessing.
The payment lifecycle
Most tools stop at “invoice sent.” PayFlowAI manages the whole journey, from the moment you finish the work to the moment cash lands and your forecast updates.
You finish the work. PayFlowAI takes care of everything else until you're paid, invoicing, delivery, payment tracking, reminders, and cash flow forecasting, in one place.
How it works
Create
Describe the invoice in plain language or connect your tools. PayFlowAI generates a professional, compliant invoice in seconds.
Collect
Your AI collections agent takes over. It sends personalized reminders, tracks every open invoice, and escalates overdue payments, all automatically.
Forecast
See your incoming cash before it arrives. Track DSO, monitor AR aging, and always know where your receivables stand.
AI Collections Agent
PayFlowAI's AI agent monitors every open invoice, sends personalized reminders at exactly the right moment, escalates intelligently, and adapts its tone to each customer relationship, so you get paid faster without damaging relationships.
Features
Built for freelancers and small businesses who'd rather ship than chase invoices. Tell the agent what you want, PayFlowAI handles the busy work, so you can focus on the work that pays.
Hit ⌘K and just tell the agent. "Invoice Acme for 3 days consulting." It fills in line items, tax, and the due date, you approve.
Choose your tone, friendly, professional, or firm. PayFlowAI drafts the reminder, references the real invoice amount and due date, and sends it in your voice. Automated dunning, without the awkwardness.
Know which outstanding invoices are at risk, your average days to pay, and your cash flow forecast. No chart-digging required.
Contacts, payment history, and risk ratings, without the bloat of a full CRM. Built for solo freelancers.
Draft → Published → Pending → Partial → Completed. See every invoice's state at a glance.
Bill in EUR, USD, GBP, see one consolidated total in your home currency. FX handled automatically.
Drop in your logo and accent color. Every PDF, hosted link, and reminder email looks like you sent it.
Save the services you sell. Auto-fill rates, units, and tax codes on every new invoice in two clicks.
Turn on card payments with Stripe. Every invoice, PDF, hosted page, and reminder gets a Pay button, and payments reconcile themselves the moment they land.
Retainers and subscriptions bill themselves on schedule. PayFlowAI generates and sends each invoice automatically, so nothing slips through the cracks.

New · EU e-invoicing
Germany already requires every business to receive e-invoices, and the rest of the EU follows through 2030. PayFlowAI already creates them, validated XRechnung and ZUGFeRD, the right format chosen for each client. A plain-language guide, plus a tool that does it for you.
Integrations
Card payments and AI are built in today. More connections to your accounting, banking, and workflow tools are on the roadmap.
Roadmap items are directions we're exploring, not dated commitments. Tell us which integration you need most, it helps us prioritise.
