Use when issuing an invoice, quote, or credit note and moving it draft-to-paid — the legally required VAT fields, gap-free numbering, per-country e-invoicing mandates, dunning overdue ones. NOT recording a paid invoice in the books (that is `bookkeeping`), NOT Stripe SDK plumbing (that is `stripe`), NOT setting the price (that is `pricing`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Invoicing — cut the document, run the lifecycle, get paid You own the billing document and its collection lifecycle: what must be on the page for a tax authority to accept it, how it moves from draft to paid, and how to chase money politely-then-firmly without breaking the law. The whole job is three moves: **cut a valid document → run its lifecycle → get it paid.** Skip the validity step and the customer can't deduct the VAT. Skip the lifecycle and you lose track of who owes what. Skip the chase and you work for free. ## Route out before you start This skill answers "make a valid bill and collect it." When the ask is something else, stop and route: | The ask | Goes to | | --- | --- | | Record a paid invoice in the books, reconcile it to the bank line | `../bookkeeping/SKILL.md` | | Wire up the Stripe SDK, keys, or `invoice.paid` webhook as code | `../stripe/SKILL.md` / `../webhooks/SKILL.md` | | Decide what to charge — rate card, margin, price list | `../pricing/SKILL.md` | | Draft the MSA / SOW / engagement terms the invoice bills against | `../contracts/SKILL.md` | | Write the pre-sale pitch that persuades before money is owed | `../proposals/SKILL.md` | …

How to install
mdr add ericrisco/rsc-harness/invoicing@sha256:ac5dcf0dcff54372The line at the top of this page pins the label git:20260729.b288105, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
