60 seconds: what BudgeHQ does and how it works.
Sound familiar?
You did the work. You sent the invoice. And now you're the one losing sleep over it.
You can't write the email
You've rewritten the same message 4 times and it still sounds wrong. Too aggressive? Too passive? You hit delete again.
You don't want to seem pushy
They're a good client. You don't want to damage the relationship. But rent is due and that invoice is 30 days late.
You don't know when to escalate
Is 45 days overdue bad enough for a formal notice? When do you mention late fees? When is it time for legal action?
How it works
Three steps. Under 60 seconds. No more agonizing over phrasing.
Enter your invoice details
Client name, amount, due date, and how many times you've already followed up.
Pick your tone and stage
Choose warm, professional, or firm. Select friendly reminder through pre-dispute notice.
Copy and send
Get a ready-to-send subject line and email body. Copy to clipboard or download the message.
What a follow-up looks like
This is a static example of one Friendly Reminder. Drop your details in to picture it — then sign up and BudgeHQ writes a fresh message for your tone, your stage, and how late they actually are.
Hi Sarah,
I hope this message finds you well. I wanted to reach out regarding the outstanding invoice for $3,500, which was due 14 days ago.
I understand things can get busy, and I appreciate your attention to this matter. Could we arrange payment this week? I'm happy to discuss if there are any questions about the invoice.
Best regards

This is what BudgeHQ actually writes
Three stages of the same overdue invoice — from gentle nudge to final notice. Every message matched to the tone you choose.
Quick nudge on invoice #204
Hi Sarah, hope your week's going well! Just a friendly heads-up that invoice #204 ($1,850) was due last Friday. I know these things slip through the cracks — could you let me know when I can expect payment? Happy to resend the invoice if that helps.
Tone: Warm
Invoice #204 — now 21 days past due
Hi Sarah, I'm following up on invoice #204 for $1,850, which is now three weeks past its due date. I've sent one previous reminder. Please confirm today when payment will be made. If there's an issue on your end holding this up, I'd rather know now so we can resolve it.
Tone: Professional
Final notice: invoice #204 (45 days overdue)
Sarah, despite two previous reminders, invoice #204 ($1,850) remains unpaid 45 days past due. Please remit payment within 5 business days. If payment isn't received by then, I'll have to pause all current work and consider further steps to recover the amount owed.
Tone: Firm
A note from the founder
Built by one person, for the part of freelancing nobody enjoys.
BudgeHQ is built and run by me, Jeremy Smith — not a big team. It does one job: hand you the right words when an invoice is late, so the follow-up goes out in a minute instead of getting pushed to next week.
It will never email your clients for you. You read the message, change whatever you want, and send it from your own inbox — you stay in control of what goes out and when.
If something feels off or you want a tone we don't have yet, tell me. Support requests come straight to my inbox.
— Jeremy Smith, Founder, BudgeHQ
“Couldn’t I just ask ChatGPT?”
You could. But a blank chatbot makes you do all the thinking — and forgets it all the next day. BudgeHQ is built for this one job, and it remembers.
A blank chatbot
- You have to know exactly what to ask — tone, timing, how firm to be — every single time.
- Guesses at how hard to push. One wrong word can bruise a good client.
- Forgets everything the moment you close the tab. You re-type the details every time.
- Won't tell you when a situation has gone too far.
BudgeHQ
- A purpose-built form. Fill in the blanks and the right message comes out.
- Three tones and four escalation stages built in — from a friendly nudge to a pre-dispute notice.
- Keeps every client and unpaid invoice in one place, ready to follow up in a click.
- Flags the risky ones — like 90+ days overdue — so you know when to change your approach.
Never lose track of who owes you
Writing the email is half the battle. The Client Tracker remembers the other half — every open invoice, how late it is, and who’s next to chase.
Every unpaid invoice in one place
See each client and open invoice at a glance, with exactly how overdue each one is.
One click to follow up
Turn any tracked invoice into a ready-to-send follow-up — client, amount and dates already filled in.
Mark it paid, keep it clean
Paid invoices drop off your list automatically, so you only ever see what still needs chasing.
Your private ledger
BudgeHQ never contacts your clients. It’s your own record of who owes you — you decide when to send.

Questions before you start
Straight answers about what BudgeHQ does — and doesn't do.
Does BudgeHQ contact my client?
No. BudgeHQ writes the email — you copy it and send it from your own inbox. It never emails, messages, or calls your clients, and nothing goes out unless you send it.
What do I get on the free plan?
One complete follow-up per month — subject line and email body — with every tone and stage unlocked. No credit card required.
What happens after I use my free message?
Your free message resets on the 1st of every month. If you need more before then, Solo is $19/month for unlimited messages plus the Client Tracker.
Can I edit the email before I send it?
Yes. The message is copied to your clipboard (Solo can also download it as a file), so you can change anything you like in your own email client before sending.
Which tones and stages can I choose?
Tones: Warm, Professional, or Firm. Stages: Friendly Reminder, Second Follow-up, Final Notice, or Pre-Dispute. Pick the combination that matches your client and how late they are.
Can I cancel Solo?
Yes, any time. Your payment receipt from Lemon Squeezy (our payment processor) includes a link to manage or cancel the subscription, or contact support and we’ll take care of it.
Is this legal advice?
No. BudgeHQ writes follow-up emails; it isn’t a law firm and doesn’t give legal advice. If a client still won’t pay after a Final Notice, talk to a lawyer or look into your local small-claims process.
