Stop writing
reminder emails.
Get paid faster.

Connect your accounting software in about 60 seconds. You can create invoices directly in Unpaid — they sync to your accounting software and your customers receive them with your branding and payment link, just like normal. Or keep creating invoices in Xero or QuickBooks and we'll sync them. 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 — whether or not you've connected an accounting software. If Xero, QuickBooks, or Stripe is connected, invoices you create in Unpaid sync to your accounting software automatically and arrive with your usual payment link and branding. If you're using Unpaid via BCC only (no accounting software connected), the invoice lives in Unpaid and goes directly to your customer with your logo and branding. Either way, every invoice gets an AI-crafted delivery email and immediately enters the reminder pipeline. You can keep creating invoices in your accounting software too — Unpaid picks them up on the next sync.

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 send it with one click 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.
