Wave DueDrop + QuickBooks
Get paid faster without leaving QuickBooks. DueDrop reads your invoices, sends friendly heads-ups as due dates approach, and warm follow-ups on anything that slips past due — all on your behalf.

DueDrop Three things that change the day you connect QuickBooks.
Upcoming and overdue invoices both get the nudge they need.
DueDrop watches QuickBooks for both — invoices coming due (so the client has a heads-up before the due date) and invoices that slipped past due. Set separate cadences for each. Warm reminders before, firmer ones after.
Client context pulls automatically
Name, amount, invoice number, due date, and prior email history — all attached to every draft, whether it's a friendly heads-up before the due date or a follow-up on an overdue balance.
One source of truth — yours
What's in QuickBooks is what DueDrop acts on. The second you mark an invoice paid there, queued reminders stop here. No second spreadsheet, no double-nudges.
Three steps. Then it runs on its own.
Connect once — DueDrop handles the rest in the background.

+ DueDrop is requesting access to your QuickBooks account
- Read-only access to your invoice list and payment status
- Read customer names, emails, and invoice history
- No access to banking, payroll, or expense data
- No write access — we never modify invoices or records
DueDrop stays in sync with QuickBooks in real time.
Create an invoice, update a due date, or mark one paid — DueDrop sees it within seconds, without you refreshing, resyncing, or doing anything else. Reminders queue automatically: a gentle heads-up as an invoice approaches its due date, and firmer follow-ups the hour it ages past due.
When an invoice goes overdue, DueDrop drafts and sends a reminder.
The draft matches your tone, fills in the client's name and invoice details from QuickBooks, and sends from your connected email — on the cadence you set. No login required on your end.
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
