Invoice #1042 — due Friday
"Hi Sam, quick heads-up that invoice #1042 ($2,400) is due Friday — payment link below. Is there anything you need from my side before then (PO number, vendor form, a re-send)? Thanks again for the brand sprint."
For freelancers who hate chasing
65–70% of late invoices get paid after a single reminder — most are a buried email or an avoidance spiral, not a "no." Duebell turns the follow-up into a system: polite, escalating reminders in your name that go out on schedule and stop the moment your client replies. Policy, not personal.
Early invites go out in order. No spam — one email when your door opens.
“I rewrote the same reminder four times — and never sent it.”
“The real cost wasn’t the amount. It was the drag.”
“Waiting longer never improved the relationship — or the odds of getting paid.”

How it works
STEP 1
Client, amount, due date, payment link. Works with PayPal, Stripe links, Wise, or a plain PDF invoice. Two minutes, no accounting software.
STEP 2
Duebell drafts four emails matched to the relationship — new client, long-term, or sensitive. Edit anything. Nothing sends without your OK.
STEP 3
Polite, then firmer, on a schedule — business hours, their timezone. A reply or a payment stops everything instantly.
The sequence
Every email sounds like you wrote it — because you approved it. Here's the default rhythm for a Net-30 invoice.
Invoice #1042 — due Friday
"Hi Sam, quick heads-up that invoice #1042 ($2,400) is due Friday — payment link below. Is there anything you need from my side before then (PO number, vendor form, a re-send)? Thanks again for the brand sprint."
Re: Invoice #1042
"Just floating this back up in case it got buried — #1042 was due Friday. Link's here again. If it's already on the way, ignore me!"
Invoice #1042 — now 9 days past due
"Following up on #1042 ($2,400), now 9 days past due. Could you confirm payment by Thursday? If something's off with the invoice, tell me and I'll fix it today."
Final notice — invoice #1042
"#1042 remains unpaid, 16 days past due. Please settle by March 3. I'd much rather resolve this simply — the payment link is right here."
Client replied at any point? The sequence pauses itself. Paid? It stops — and can say thanks.
Relationships intact
Emails go out under your name; replies land in your inbox. Your client talks to you, never to a tool. No robot voice, no third-party letterhead.
Duebell is software you use to send your own reminders for your own B2B invoices. You stay in control of every word — we just make sure the words actually get sent.
Late-fee wording and legal-rights mentions (like NY & CA freelancer payment laws) are optional toggles — off by default, there when you need leverage. Everything firm gets declared up front — the late-fee line, the pause rule — so when it triggers, it reads as process, not punishment.
Autopilot is opt-in. Until you turn it on, every email waits for your click. Most people relax after the first recovered invoice.

Who's ringing the bell
I'm Han — building Duebell solo. It started with a question I asked 30+ freelancers: how do you actually deal with a client paying late? Their answers wrote half of this product — the pre-due wording, the day-after rule, a final notice that reads as process, not punishment. The research is public: read the thread on Indie Hackers. And hello@duebell.co isn't a support desk — it's just me on the other end.
Questions at the door
Emails are sent under your name from a verified Duebell address, and every reply goes straight to your real inbox. To your client it reads as you — because it is you; you approved every word. Direct Gmail sending is on the roadmap.
No. Duebell is software you use yourself to follow up on your own business-to-business invoices, in your own name. We never contact your clients on our letterhead, and Duebell isn't for consumer debts.
Solo is $19/month for up to 15 active invoices; Pro is $39 for unlimited. The first 20 founding members lock $9/month for life — founding checkout is open now. If it recovers one late invoice, it's paid for itself for years.
Founding invites go out first, in waitlist order, within the next few weeks. You'll get exactly one email when your door opens.
Because the reminder was never the hard part — the writing is. The alarm fires, and the awkward email still has to be drafted, so it gets snoozed for days. One freelancer told us their calendar system collapsed the moment 3–4 invoices were open at once. Duebell replaces the blank screen with a 30-second review: the draft is already written, in your voice, and it stops the moment your client replies.
They would if Duebell auto-blasted your clients — it doesn't. Every email waits for your approval, the sequence pauses the instant a client replies, and the tone matches the relationship (new, long-term, sensitive). What we heard in research, from people who actually enforce their terms: clear, consistent follow-up resets relationships more often than it ends them. It's the silence and resentment that do the damage.
