Use when checking Australian tax invoices, recipient-created tax invoices (RCTIs) or Peppol eInvoices before GST credits are claimed or supplier invoices are issued.
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
# Tax invoice, RCTI and eInvoice review ## Inputs Purchase and sales invoices for the period (PDF, paper or Peppol eInvoice), the GST transaction report they support, supplier and customer ABNs, any written RCTI agreements, dated GST-registration evidence for both purchasers and suppliers, the entity's GST accounting basis and reporting period, and the supplier master's current payment details with its change history. ## Workflow 1. Tie the invoice population to the GST report. Every credit claimed needs an invoice or a documented reason one is not required; list credits with no document and documents with no credit. 2. Separate purchase and sales invoices in the tie-out. Test each purchase invoice against the tax invoice information requirements for its value band, taken at use time from the ATO page and GSTR 2013/1. Test each sales invoice against the applicable requirements before issue. Record which required detail is missing rather than judging the invoice as a whole. Where an invoice mixes taxable and non-taxable items, check it shows which items are taxable, the GST payable and the total. …

How to install
mdr add ryanduguid/australian-accounting-skills/tax-invoice-review@sha256:d17e36ae154edfd4The line at the top of this page pins the label git:20260929.d54ec02, 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.
