Auto Invoice Chaser for Freelancers

A tool that connects to your invoicing and automatically sends polite, escalating payment reminders to clients who haven't paid, so freelancers get paid faster without the awkward chasing.

Market timing

Why now

Freelancing exploded post-2020, over 70 million Americans now freelance, and late payment is consistently their #1 complaint. At the same time, invoicing and payment APIs (Stripe, QuickBooks, Wave) matured enough that a solo dev can plug into a freelancer's existing payment flow in days, not months. The big invoicing suites bury chasing as a minor feature, but a focused, cheap tool that does ONE thing, get you paid without the awkward emails, fits how freelancers actually adopt tools: one painful problem at a time.

Red Flags

Pro

It's a feature, not obviously a company. Bonsai, FreshBooks, and QuickBooks all bundle invoice reminders. Winning means being dramatically better or cheaper at the one job, a narrow wedge.

Freelancers are famously price-sensitive and tool-fatigued. Converting a free spreadsheet-and-email habit into a $12–29/mo subscription is a real adoption hurdle; many try free and churn.

Integration dependency: you live at the mercy of Stripe/QuickBooks/Wave API terms. If a platform restricts access or builds the feature natively and well, your wedge narrows overnight.

Competitor Breakdown

Pro
Bonsai$25–$79/mo

A full freelance-business suite, overkill and pricey if you just want automated chasing, with heavy onboarding.

FreshBooks$19–$60/mo

Accounting-first; late-payment reminders are buried, not smart, and not escalating.

Manual email & spreadsheetsFree

The awkward status quo, freelancers hate sending 'just following up' emails, which is exactly the pain you remove.

Who it's for

Solo freelancers and small agencies (designers, developers, consultants) who invoice clients and routinely wait 30–90 days, or chase awkwardly, to get paid.

How you'll get customers

Where your first customers realistically come from:

  • Freelancer communities, r/freelance, Indie Hackers, and designer/dev Slacks, lead with a free 'late payment script' before pitching.
  • SEO, Rank for 'how to get clients to pay on time' and 'late payment reminder template'.
  • Tool marketplaces, List in the Stripe and QuickBooks app directories where freelancers already manage invoices.

How to start

1
Build the core loop: connect a freelancer's Stripe or QuickBooks, detect unpaid invoices past due, and auto-send a polite reminder sequence.
2
Recruit 10 freelancers from r/freelance and designer Slacks to run it on real overdue invoices and measure days-to-payment.
3
Turn 'got paid 12 days faster on average' into proof and write SEO content around 'how to get clients to pay on time'.
4
Add escalating tone options and a 'late fee' nudge, then charge $12/mo for up to 10 clients.

  • Define the exact customer in one line: Solo freelancers and small agencies (designers, developers, consultants) who invoice clients and routinely wait 30–90 days, or chase awkwardly, to get paid.
  • Talk to 10 of them, ask about the problem, don't pitch. Look for real frustration.
  • Collect a waitlist or take a pre-order to prove they'll act, not just nod.
  • Build the smallest version that delivers the core value, a landing page plus one working feature. Don't polish.
  • Cover the skill gaps yourself or partner up: Web development, Invoicing/payment API integrations (Stripe, QuickBooks), Email automation, Freelancer-community marketing.
  • Put it in front of 1–3 friendly early users and fix whatever confuses them.
