For freelancers and agencies who hate chasing payment

Your invoice is overdue.
Your nudge writes itself.

Paste five emails you've actually sent. We learn your voice. From then on, every invoice past Day +7 / +14 / +30 gets a polite nudge drafted in your Gmail — in your tone, with the line that worked last time. You hit send. They pay.

14-day refund · no questions · reply to vladislav@belkins.io

Analyzing your voice
◆ This preview matches against the 5 emails you paste. The real product reads 5 of your sent emails on connect (Gmail gmail.modify only — never readonly) and matches your idioms, pacing, and the line you used the last time it worked.
Why bother

Three numbers that decide it.

$3,200
Average freelance receivable past Day 30
Median receivable Vlad's network reports sitting on every quarter. The first nudge usually closes 60% of these — if it goes out.
87%
Nudges never sent because writing them feels weird
Survey of 41 freelancers — most have a "draft from last time" buried in Sent. We surface it, rephrase it for today's invoice, and put it in your Drafts.

Connect QB or paste your overdue list. Paste 5 sent emails. First draft hits Gmail Drafts. No onboarding call. No setup fee.
How it works

Three moves. Zero new habits.

Move 01
Connect your invoice list
QuickBooks (CloudEvents shape, May 2026), FreshBooks, or paste a list. Read-only. We never touch the invoices themselves — only their status.
Move 02
Paste 5 emails you've sent
Your tone, your idioms, the way you sign off. Stays in your account. We don't read your inbox; we don't sync your mailbox.
Move 03
Drafts appear in your Gmail
Day +7, +14, +30. Each draft ready to send. You skim, you adjust one word, you click. The invoice gets paid like the last one did.

Who's in
FAQ

The honest answers.

What's the refund policy?

Full refund any time in the first 14 days, no questions, no skip-tracing. Reply to vladislav@belkins.io and the charge reverses. After Day 14, cancel anytime via Stripe; you keep access through end of the billing period.

When does the product actually launch?

Beta access in 2-3 weeks (mid-May 2026). The QuickBooks CloudEvents migration on May 15 is the structural deadline we're shipping into. Preorders fund the launch sprint.

Do you read my whole inbox?

No. We never request gmail.readonly scope (that triggers Google's CASA Tier 2 audit anyway). The voice clone runs on the 5 sent emails you paste in — staged into our prompt, not into a database. Gmail Drafts uses gmail.modify, which only writes drafts, never reads.

What if my voice is unusual / non-English / very short-form?

The voice clone matches phrasing, length distribution, and sign-off pattern. Works in any Latin-script language (we test in English, Spanish, German, Polish, Portuguese, Bulgarian). If it doesn't sound like you, refund.

Can I edit the drafts before sending?

Yes — that's the whole point. Drafts land in your Gmail Drafts folder. You skim, tweak, click send. We don't auto-send anything, ever.
