# Step 8 — Jane creates the invoice for the completed SO and posts it.
# Test:
#   A) SO has invoice_status = 'to invoice' after delivery
#   B) Jane creates the invoice
#   C) Invoice draft has correct lines, taxes, payment terms
#   D) Jane posts → invoice posted, account moves balanced
#   E) Notification fires (best-effort)
