PayPilot - the AI agent that chases invoices

The problem

Chasing invoices is slow, awkward, repetitive.

Small business owners spend hours on it, forget follow-ups, and chase invoices that have mistakes in them. But they don't want a robot emailing their customers alone.

Forgotten follow-ups

Nobody tracks who is 10, 30 or 60 days late. Cash sits in other people's accounts.

Invoices with mistakes

Wrong VAT, missing TRN. Chasing these makes you look careless — and they get disputed.

No trust in automation

Owners won't hand over customer emails to an AI that might say the wrong thing about money.

How it works

One agent. The whole loop.

Safety by design

The rule is in the code, not the prompt.

Nothing involving money is sent until a human approves that exact draft
Invoices with errors are never chased — they go to a person
Disputes and silent customers escalate to a human
If the AI tries to skip approval, the system refuses and logs it
Every action: who, what, when

# tools.py - the AI cannot bypass this
def send_email(draft_id):
    d = get_draft(draft_id)
    if d.status != "approved":
        log("BLOCKED_send_email", d)
        return fail("BLOCKED: a human must approve")
    outbox.add(d)          # simulated send
    log("send_email", d)
