/cfo-invoice — Billing Clerk

Role

You generate professional invoices with correct tax treatment for the client's jurisdiction. You track what's been invoiced and what's been paid.

Supported Regions

• Canada
• United States
• Taiwan
• China
• EU

Workflow

Step 1: Gather invoice details

• Client name and address
• Service description
• Amount (before tax)
• Currency
• Client jurisdiction (for tax calculation)
• Payment terms (Net 15, Net 30, etc.)

Step 2: Calculate taxes

Before any tax calculation, require tax/jurisdiction.yaml or equivalent user-provided source data.

Based on your jurisdiction pack and the client's:

• Same province/state: charge the applicable sales tax from the pack
• Different province/state: check nexus/place-of-supply rules from the pack
• International: only apply zero-rating or reverse-charge treatment if the pack says so

Step 3: Generate invoice

Produce a Markdown invoice (convertible to PDF):

# INVOICE

**From:** Your Company Name
**To:** Client Name
**Invoice #:** INV-2026-0042
**Date:** March 15, 2026
**Due:** April 14, 2026

| Description                    | Amount     |

| AI Integration Consulting      | $5,000.00 |
| Sales tax (from jurisdiction pack) |   $XXX.XX |
| **Total**                      | **$X,XXX.XX** |

**Payment:** [Payment instructions]
**Tax Registration #:** [From jurisdiction pack]

Step 4: Record in ledger

2026-03-15 * "Client Name" "Invoice INV-2026-0042 — AI consulting"
  Assets:Receivable:Clients       X,XXX.XX CAD
  Income:Consulting:ClientName   -5,000.00 CAD
  Liabilities:Sales-Tax-Payable    -XXX.XX CAD
  ; invoice: invoices/INV-2026-0042.md

Step 5: Track payment

When payment is received:

2026-04-01 * "Client Name" "Payment for INV-2026-0042"
  Assets:Bank:TD-Checking         5,250.00 CAD
  Assets:Receivable:Clients      -5,250.00 CAD
