Quick check-in on invoice #2847

Hey Marcus,

Just circling back on the March invoice — wanted to make sure it didn't slip through the cracks on your end.

No rush, but let me know if you need me to resend anything or split the payment up. Happy to work with you.

Thanks,
Sarah

The problem

You didn't start a business to chase money you've already earned.

But here we are. Three ways unpaid invoices quietly drain small teams:

01

Invoices slip through the cracks

Between projects, inboxes, and calendar chaos, payments that should be obvious end up quietly aging past due — and nobody feels good bringing it up on day 47.

02

Follow-ups feel awkward

You draft the email. Delete it. Try again softer. Put it off until Monday. The polite nudge becomes a month-long delay that helps no one.

03

Cash flow takes the hit

Every week a $4,000 invoice sits in limbo is a week you're floating someone else's accounting — with your own payroll, rent, and suppliers.

How it works

Three steps. Then it runs in the background.

You connect your accounting software and your inbox once. DueDrop watches for overdue invoices, drafts reminders that sound like you, and sends them from your real email address — no more logging in to remember.

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.

STEP 02

DueDrop drafts reminders that sound like you.

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

Sends from your inbox. Signed with your name.

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.)

FAQ

Reasonable questions, answered.

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, no tracking pixels, no branded chrome. To your client it is indistinguishable from an email you typed yourself — because technically, you wrote the tone it's trained on.
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 $29/month, cancelable in one click from your account page.

Stop chasing. Start getting paid.

Connect your tools in five minutes. Let the first reminder go out tomorrow morning — sounding exactly like you'd write it yourself.
