AI-powered emails
Claude writes personalized, professional reminders that match your tone, brand, and customer relationship.
Five-stage reminder sequence, every email needs your approval
Courtesy heads-up before the due date, then a five-stage reminder sequence from day 3 to day 30. Each reminder is drafted by AI and queued in your inbox with Approve, Edit, or Skip buttons. Nothing reaches a customer until you say yes.
You're always in control
Nothing is sent until you're ready. Review your imported invoices, preview exactly what your customers will receive, choose which overdue invoices to follow up on, and go live on your terms. Pause any invoice or stop all emails at any time from your dashboard.
Reads replies, pauses on disputes, flags resend requests
Every customer reply is read and classified — disputes, questions, payment promises, and resend requests. The sequence pauses on its own and you get a notification with the detected intent so you can decide the next step.
Dispute & pause management
Disputes pause reminders and notify you instantly. Questions pause for 3 days, "will pay" promises for 14 — then prompt you to resume when the pause window ends.
Payment verification & receipts
When payment is detected on your next sync, the reminder sequence stops. Your customer gets a branded payment receipt confirming the amount and date.
Create & deliver invoices
Not on Xero or QuickBooks? Create invoices directly in Unpaid — the delivery email arrives with your logo, branding, and payment link. You approve each delivery email by default; auto-send is an opt-in setting once you trust the drafts.
Weekly digest
Every Monday, get a summary of collections, reminders sent, pending actions, and email deliverability health.
Customer payment-risk scoring
Each customer gets a trust score from 0 to 100, built from their payment history in your account. Customers on the Australian Government's Payment Times Reports Register also show their reported payment times. Use both to prioritise follow-ups on the customers most likely to miss the next due date.

Every customer email crosses your desk first
For each overdue invoice, Unpaid drafts the reminder and queues it in your inbox. Click Approve, Skip, or Edit — no login needed, no surprise sends. You stay accountable for every message that reaches a customer.
Review the emails that matter
Every reminder — day 3, 7, 14, 21, and 30 — comes to your inbox for approval before sending. Each shows the customer, amount, escalation stage, and full email body. Approve it, tweak the wording, or skip it entirely.
Hi Michael,
I hope this message finds you well. I'm writing regarding invoice #INV-2024-089 for $4,200.00, which was due on January 28th.
I understand things can get busy, but I'd appreciate it if you could arrange payment at your earliest convenience...
Relationship alert: Acme Corp is a long-term customer (12 invoices, always pays within 21 days). Consider a softer tone for this reminder.
Pause and escalation safeguards
Unpaid flags when a customer was recently contacted, when a trusted client might find a late-stage reminder aggressive, or when someone's getting too many emails. So you never look unprofessional.
Everything at a glance
See what's been collected, what's overdue, and what needs your attention. Most users approve reminders straight from email — the dashboard is there when you want the full picture.

Hi Michael,
I wanted to touch base about invoice #INV-2024-089 for the Wilson project consulting work ($4,200).
It was due on January 28th — just wanted to make sure it hasn't slipped through the cracks.
Happy to chat if there are any questions about the scope.

Risk signals from official Australian sources
After you connect Xero or QuickBooks, Unpaid checks your customers against two official registers in the background. No setup, and it's included in every plan.
Payment Times Register check
We look up your customers on the Australian Government's Payment Times Reports Register, by the ABN recorded in Xero or QuickBooks, or failing that an exact match on the business name. Large businesses that report there get a rating from their reported payment times, from Fast Payer to High Risk. Most small businesses don't have to report, so they won't appear.
ABN and GST check
We look up each customer on the Australian Business Register, by the ABN recorded in Xero or QuickBooks, or failing that an exact match on the business name, and show their ABN status, GST registration and entity type. Each customer found on the register gets one flag on their profile and your dashboard, the first that applies: a cancelled ABN, an ABN that became active in the last 12 months, or no GST registration.

Frequently asked questions
Everything you need to know about Unpaid
Connect your accounting software in about 60 seconds, and keep creating invoices in Xero or QuickBooks as you do now — Unpaid picks them up on its next sync. You can also just BCC us on your invoice emails — no integrations needed. Your first reminders can go out within minutes.
Unpaid imports your invoices but doesn't send anything yet. You'll see a Go Live screen where you can review what's been imported, preview the exact emails your customers will receive, and choose which overdue invoices you want to follow up on. You can also hold overdue reminders for 24 hours if you want time to double-check. Nothing goes out until you're completely ready.
No problem. Just add your unique Unpaid BCC address when emailing invoices to customers. Our AI reads the email and any PDF attachments, extracts the invoice details, and starts tracking it automatically.
Emails are sent from your name and read like personal, hand-written messages — but you are always the human in the loop. AI drafts each reminder based on the customer and the invoice; you preview and approve every one before it sends. The result is professional, on-brand mail that you stand behind.
When a customer clicks "I've Paid", Unpaid pauses the reminder sequence and starts watching for the payment in your Xero, QuickBooks, or Stripe data. Once it lands, your customer gets a branded payment receipt, you get a "Payment Verified" notification, and the sequence stays closed. If the payment can't be verified after 3 days, you get notified so you can decide whether to send a polite follow-up.
Our AI detects dispute intent in customer replies and auto-pauses reminders for 7 days. You're notified immediately with the customer's message so you can resolve it directly. Reminders only resume once you're ready.
It starts before the invoice is even due — Unpaid sends a friendly courtesy reminder a couple of days before the due date so your client has time to arrange payment. If they miss it, a 5-stage overdue sequence kicks in: Day 3 (friendly nudge), Day 7 (follow-up), Day 14 (firm reminder), Day 21 (urgent), and Day 30 (final notice). Every stage is drafted by AI and queued in your inbox with Approve / Edit / Skip buttons — nothing reaches your customer until you say yes.
Yes, unless Xero or QuickBooks is connected. Then create your invoices there, as you do now, and Unpaid picks them up on its next sync (a Xero invoice once it's approved). Otherwise, an invoice you create in Unpaid goes directly to your customer with your logo and branding, gets an AI-crafted delivery email, and immediately enters the reminder pipeline.
Unpaid's AI reads every customer reply. If someone asks for the invoice again, it's flagged and a fresh delivery email is queued for your approval — with the original payment link and details — so you can approve and send it from your inbox instead of digging through your sent folder.
Absolutely. Choose from softer, standard, or firmer tones. You can also set regional styles and the AI will adapt its language and approach accordingly.
Yes. We use bank-level encryption for all data in transit and at rest. OAuth tokens are encrypted with separate keys, and we verify all webhook signatures. Your invoice data is synced securely and never shared.
Of course. We offer a 14-day free trial with full access to all features — no credit card required. Cancel anytime if it's not the right fit.
