Invoice Engine — Complete Invoicing & Accounts Receivable

A zero-dependency agent skill for end-to-end invoicing — from quote to payment to reporting.

Quick Start

When the user says "create an invoice" or "bill [client]":

Check if client exists in memory (see Client Registry below)
If new client → run Client Onboarding
Generate invoice using the Invoice Builder
Present for review → finalize
Track in the Invoice Ledger

1. Client Registry

Maintain a YAML client database in your workspace:

# clients.yaml
clients:
  - id: "CLI-001"
    name: "Acme Corp"
    contact: "Jane Smith"
    email: "[email protected]"
    address:
      line1: "123 Business Ave"
      line2: "Suite 400"
      city: "New York"
      state: "NY"
      zip: "10001"
      country: "US"
    tax_id: "US-EIN-12-3456789"
    payment_terms: "net-30"       # net-15, net-30, net-45, net-60, due-on-receipt, custom
    preferred_currency: "USD"
    default_tax_rate: 0           # 0 for B2B cross-border, local rate for domestic
