Get paid without sounding like collections.

DueDrop reads the email thread you already have with each client and drafts the next overdue-invoice follow-up in your voice.

Review it first. Send it from your own inbox. And the moment your client replies, DueDrop stops.

So it sends the overdue notice on Thursday.
Your inbox knows
“Hey Sarah — sorry, this one's on me. Check goes out Friday.”
So DueDrop says nothing until Friday has passed.

Quick check-in on invoice #2847

Hey Marcus,

Just circling back on the March invoice — the $2,400 was due on the 23rd and I wanted to make sure it didn't slip through the cracks on your end.

No rush, but if it's easier you can click this link to view and pay it online. Otherwise just let me know if you'd like me to resend or split it up.

Thanks,
Sarah

The difference

No reminder templates to write.

Most invoice tools ask you to write a message once and then send some version of it to everyone. DueDrop starts somewhere else: the conversation you already had with this client. It looks at how you write to them, what you call them, how formal the relationship is and what has already been said — then drafts the next follow-up for this invoice.

  • — No reminder library to build.
  • — No {FirstName} template to perfect.
  • — No pretending every client relationship sounds the same.
A template, sent to everyone

Subject: Payment reminder — Invoice #2847

Hi Marcus,

This is a reminder that invoice #2847 is now overdue. Please remit payment at your earliest convenience.

Thank you.

What DueDrop drafts for this client

Subject: Quick check-in on the March invoice

Hey Marcus,

Just wanted to circle back on the March invoice and make sure it didn't get buried. Let me know if you need me to resend anything on my end.

Thanks,
Sarah

You see the draft before it goes anywhere.

Reply-aware

Paid isn't the only signal that matters.

Your accounting system can tell you whether an invoice is still unpaid. It cannot tell you that your client emailed twenty minutes ago to say the check goes out Friday.

DueDrop watches the thread as well as the ledger. When your client replies, the follow-up cadence for that invoice pauses automatically — even though the payment hasn't landed yet and the invoice still reads overdue.

No automated nudge arriving the morning after they already answered you.

How it works

From overdue invoice to human follow-up.

Your accounting system tells DueDrop which invoices are overdue. Your inbox tells it how you already talk to that client. DueDrop drafts the follow-up — and every account starts in review mode, so nothing sends until you approve it.

STEP 01

Connect your tools in five minutes.

Link QuickBooks, Xero, FreshBooks, or Wave on one side — Gmail, Outlook, Yahoo, or Zoho Mail on the other. OAuth only, read-only where it can be, and you can revoke access any time.

Password-free sign-in
· bank-grade encryption
STEP 02

DueDrop drafts it. You approve it.

It reads prior threads with each client to match your tone, then drafts the reminder, chooses a send window you set, and queues it — all without you opening the app. And the moment a client replies, DueDrop pauses the cadence for that invoice automatically.

STEP 03

Sent from your inbox. Stopped by their reply.

Reminders go out through your actual Gmail, Outlook, or Yahoo account — not a relay, not a "noreply" domain. Replies land in your inbox as normal. Your clients see a note from you, because technically, it is.

What Marcus sees when your DueDrop reminder arrives. No badge. No "sent via." It's from you — because it's sent from your address.

(The send lands in your DueDrop audit log — invisible to your client.)

Already have invoice reminders in QuickBooks or Xero? Good.

You may not need DueDrop. QuickBooks, Xero, FreshBooks and Wave all include automatic reminders, you can edit the wording, and they're part of what you already pay for. If a scheduled message you write once is getting your invoices paid, use the feature you already have.

DueDrop is for the follow-up that should read like the next email in an existing client relationship — not another billing notification.

Built-in reminders
  • Know the invoice status
  • Send the message you configured in advance
  • Follow a schedule based on the invoice
  • Stop when the invoice is marked paid
DueDrop
  • Knows the invoice status and the client conversation
  • Drafts each follow-up from that conversation
  • Writes in the way you already write to that client
  • Pauses when the client answers, not just when the invoice is paid

That's the difference. If it isn't worth $49 a month to you, the built-in reminders are genuinely fine.

FAQ

Reasonable questions, answered.

Why wouldn't I just use the invoice reminders in QuickBooks or Xero?
You should, if a standard scheduled reminder does the job — it's included in what you already pay for. DueDrop is different because it drafts each follow-up from your existing conversation with that specific client, and pauses when the client replies rather than only when the invoice is marked paid. It's built for businesses where the relationship matters as much as the invoice.
Does DueDrop send anything as soon as I connect it?
No. Every new account starts in review mode: DueDrop prepares the draft and waits for you. Edit it, approve it, or skip it. You decide when — or whether — you want any of it to run automatically, and you can switch that on per client rather than all at once.
What does DueDrop need access to in my email, and why?
Enough to read the prior thread with the clients you invoice — that's what each draft is written from — to send approved follow-ups through your mailbox, and to notice replies so it knows when to stop. Your accounting connection is read-only; we never modify your records. It's OAuth throughout, so we never see or store your password, and you can revoke either connection at any time from your DueDrop account or directly in Google or Microsoft.
Will my clients know this was sent by software?
No. The email leaves your actual Gmail, Outlook, or Yahoo account, from your address, with your signature. There's no "sent via" footer and no branded chrome — it reads like an email you typed yourself, because it's written from the way you already write to that client. One thing worth knowing: by default DueDrop adds open tracking (a 1×1 pixel) and wraps links so you can see whether a reminder was read. You can switch both off in your settings, and then nothing at all is added to the email.
Does it use AI? What happens if it writes something weird?
Yes — it uses a language model to draft, but every reminder follows your past emails as a tone guide and the copy is short and conservative by default. You can review drafts before they send, or flip on full auto-send for clients you trust. You can pause or edit any draft with one click.
How does it know when an invoice is overdue?
It syncs with your accounting tool (QuickBooks, Xero, FreshBooks, or Wave) to read invoice status, due dates, and payment records. When something crosses the threshold you set — 3, 7, 14 days — it queues a reminder.
What if someone replies to a DueDrop email?
The reply lands in your inbox exactly like any other email. DueDrop watches for replies and automatically stops the reminder cadence for that invoice. If someone says "payment is coming Friday," nothing else gets sent until you decide.
Is my data secure?
OAuth tokens only — we never store your email password. All data is encrypted at rest and in transit. We only request the permissions needed to read invoice status and send from your address. You can revoke access in one click, and we delete your data on cancellation.
What industries does this work for?
Any service business that sends invoices: agencies, consultants, HVAC, plumbing, electrical, general contractors, accountants, law firms, property managers, staffing, architects, engineers, logistics — if you use QuickBooks/Xero/FreshBooks/Wave, it works.
Can I customize when and how often reminders go out?
Yes. Set the cadence (e.g. day 3, 14, 30), send windows (business hours only), escalation tone, and which clients are excluded entirely. You can override any default per-client.
What happens after the 14-day trial?
If you don't add a card, the account simply pauses — no charge, no ghost subscription. If you do subscribe, it's $49/month, cancelable in one click from your account page.

Your next overdue invoice doesn't need another template.

Connect your accounting system and your inbox. DueDrop will draft the first follow-up from the conversation you already have with that client — and nothing sends until you approve it.
