For QuickBooks Online
QuickBooks knows the invoice. DueDrop knows the conversation.
Keep QuickBooks as your source of truth. DueDrop reads the email thread you already have with each client, drafts the next overdue-invoice follow-up in your voice, and pauses the moment the client replies.
It starts in review mode, so nothing sends until you approve it.

Invoice #2847 · Northlane Design
QuickBooks knows
$2,400.00 · 14 days overdue
Your inbox knows
“Hey — sorry, this one's on me. Check goes out Friday.”
DueDrop uses both. So nothing goes out on Thursday.
QuickBooks already has invoice reminders.
QuickBooks Online lets you schedule up to three automatic reminders, time them up to 90 days before or after the due date, and edit the subject line and message. If a scheduled message you write once is all you need, use the feature you already pay for — this page isn't trying to sell you a second copy of it.
DueDrop adds the part QuickBooks doesn't have: the conversation happening in your inbox.
- which invoice is overdue
- who owes it and how much
- when it was due
- when it gets paid
- how you normally talk to this client
- what the existing conversation sounds like
- where the conversation left off
- whether the client has already replied
- One message you wrote in advance goes to every customer, however different those relationships are.
- The reminder is sent by QuickBooks, not from the mailbox you normally email that client from.
- It follows the schedule regardless of what the customer said to you last week.
- It stops when the invoice is marked paid — not when the customer replies to say payment is on the way.
No template required.
Instead of asking you to write the perfect overdue-invoice email once and reuse it forever, DueDrop reads the existing thread with that client and drafts the next message.
Hi Marcus,
This is a reminder that invoice #2847 is overdue. Please submit payment at your earliest convenience.
Thank you.
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 anything resent on my end.
Thanks,
Sarah
When your client answers, the follow-ups stop.
QuickBooks knows whether an invoice has been paid. DueDrop also knows whether the conversation has changed. If your client replies “payment is going out Friday”, the cadence for that invoice pauses automatically — even though the invoice still reads overdue in QuickBooks.
No automated follow-up landing after your client has already answered you.
QuickBooks stays the source of truth.
Connect QuickBooks and DueDrop reads the invoice information it needs — invoices, customers, due dates and payment status. The connection is read-only; we never create, modify or delete anything in your account.
Then connect your mailbox so DueDrop can draft from your existing client threads and send approved follow-ups from your own address. Your first messages stay in review mode until you approve them, and you can revoke either connection at any time.

Questions before you connect anything.
Does DueDrop replace the reminders in QuickBooks? +
No, and you can run both if you want — though most people turn the QuickBooks ones off for the clients they hand to DueDrop, to avoid two messages about the same invoice. QuickBooks stays your source of truth for invoicing and payment status; DueDrop only handles the follow-up email.
Does DueDrop change anything in my QuickBooks account? +
No. The QuickBooks connection is read-only. DueDrop pulls invoice status, due dates, customer details and payment records, and never creates, modifies or deletes anything in your books.
How quickly does it notice a payment? +
QuickBooks sends DueDrop a webhook, so a payment is usually picked up within seconds. Any queued follow-ups for that invoice stop immediately — you never have to remember to cancel anything.
Does this work with QuickBooks Desktop? +
Not yet — QuickBooks Online only. Desktop uses a fundamentally different sync model. If you're on Desktop and want this, tell us; the demand signal helps us prioritise.
What if I have several QuickBooks companies? +
Each needs its own DueDrop workspace, because QuickBooks scopes its OAuth tokens to a single company. Your subscription covers every workspace you create, so there's no extra charge for the second company.
What does DueDrop need from my email? +
Enough to read the prior thread with the clients you invoice — that is what each draft is written from — to send approved follow-ups through your mailbox, and to notice replies so it knows when to stop. It is OAuth throughout, so we never see your password, and you can revoke access at any time from your DueDrop account or directly in Google or Microsoft.
