Dueflo
AI that collects overdue invoices for QuickBooks users
Hey Indie Hackers, I'm Abdulaziz, a full-stack developer from Tashkent, Uzbekistan. I built Dueflo — an AI-powered invoice collection tool for US small businesses using QuickBooks Online.
The problem I kept hearing: Business owners doing great work but writing off thousands every year because chasing payments felt too awkward. A freelance designer told me she wrote off $12,000 last year because she didn't want to "bother" her clients. $12,000. Gone. Because of social anxiety around asking for money she already earned.
56% of US small businesses are owed money from unpaid invoices right now. The average? $17,500 sitting uncollected. If you're running QuickBooks and have invoices 30+ days overdue, this is built for you.
So I built Dueflo.
How it works:
→ Connect QuickBooks Online in 30 seconds
→ Dueflo finds every overdue invoice automatically
→ AI writes a unique, personalized email for each client — referencing the specific work delivered
→ Sends Tuesday–Thursday at 10am (highest open rates)
→ Escalates in tone over 45 days — from friendly reminder to final notice
→ Stops automatically the moment invoice is paid
→ Clients never know Dueflo exists
Plans start at $49/month. If you've got overdue invoices sitting in QuickBooks right now, sign up — 14-day free trial, no card required.

I ran into the same thing with client work, the painful part wasnt finding the overdue invoice, it was writing reminder 2 once the thread got awkward. I tried QuickBooks nudges first, looked at tools like Dueflo, and now I'm building ChaseFlow around the same chase layer for smaller freelancers, ngl the social-anxiety angle is the part I'd lean into harder.
This is brilliant Abdulaziz. The $12,000 designer story alone is enough to go viral in the right communities, freelancers and small business owners would share this everywhere if they saw it. Have you thought about a content strategy around these kinds of stories to drive more QuickBooks users to Dueflo?
the psychological shield framing is spot on. we build agent deploy infra on our side and the hardest part was always the handoff moment too - knowing when the agent should step back and hand the thread to the human. sounds like you nailed that. quick q: how do you handle clients who reply-all or loop in their accountant mid-sequence? that edge case always broke our early flows
that's actually elegant. keeps you in the thread even when clients do the typical reply-all chaos. clean solution
Good edge case. When a client replies-all or loops in their accountant, the reply lands in your inbox - Dueflo sets the reply-to as your own email, so the client is essentially emailing you, not some automation tool.
The sequence keeps running unless you manually pause it from the dashboard (one click). So if an accountant jumps in saying 'we'll pay by Friday,' you pause the sequence, handle it yourself, and resume or close it once resolved.
Clients never see any mention of Dueflo - the emails come from your name, your domain, your tone. To them it looks like you wrote it.
Abdulaziz, the story of the $12,000 freelancer is the insight hidden in your post.
She didn’t fail to send a follow-up email since she failed to send it out of embarrassment. Dueflo is not only an automated email service but also a psychological shield against the awkwardness many freelancers cannot identify. It is more significant than being an "invoice tool."
Curious to know what happens once the client responds to the AI-generated email? That is the point of transition, where trust is either maintained or broken.
I am currently working as a Behavioral UX consultant, and this domain is my interest area. I would be glad if you let me review your product from that perspective.
Thanks - the psychological angle is actually the core insight behind Dueflo. Most AR tools focus on automation mechanics, but the real blocker is the business owner's discomfort. Once you remove that, collection happens naturally.
On client responses: when a client replies, it lands directly in the owner's inbox - Dueflo sets the reply-to as their own email, so the client is just emailing them as normal. They never see any mention of Dueflo.
The sequence doesn't auto-pause - the owner sees the reply and decides what to do. If the client says "paying Friday," they pause the sequence with one click and handle it themselves. If it's just an acknowledgement, they let it keep running. Full control stays with the owner at every step.
That trust-transition moment you're describing - where the owner needs to step in personally - is exactly why we kept it manual rather than trying to automate the response handling. Automation gets you to the conversation; the human closes it.
Would genuinely welcome your UX perspective, especially around that handoff point. Happy to jump on a call or share early access if you want to see how it flows in practice.
The transition from the automated conversation (as described above) to a human at that handoff point is where many different tools typically see drop-off, and this is not related to the technical side of automation, rather it is behavioural. When owners receive their first human response, the perceived risk increases, and many freeze up.
I would like to conduct a targeted behavioural audit of that transition to help determine where the UI gives owners an indication to jump in, whether the way the UI frames the second response contributes or alleviates anxiety for the owner, and whether using the “pause with one click” feature provides a sense of control or if it feels like the system is transferring ownership of the conversation to the owner.
I typically perform structured 72-hour audits of the following:
- Drop-off points
- Friction maps
- Copy and flow items that need to be adjusted/changed
If you are open to it, I will complete the audit based on early access and ensure that you receive an actionable output rather than just the bullet points in a report that will go into a folder.
