GST e-invoicing: does it apply to your shop yet?
A plain-language explanation of e-invoicing thresholds, IRN, QR codes on receipts, and what to do before the limit drops again.

What e-invoicing actually is
It is not an emailed invoice. It means your B2B invoice is reported to a government Invoice Registration Portal, which returns an IRN — a unique reference number — and a QR code that must be printed on the invoice.
Who it applies to
It applies above a turnover threshold, and that threshold has been reduced repeatedly since it was introduced. Because it keeps moving, the practical advice is simple: if you are anywhere near the current limit, get software that can do it before you are forced to.
B2C is different
For most retail counters, B2C invoices are not reported to the IRP. But above a turnover limit, B2C invoices must carry a dynamic QR code for payment. That is a display and printing question, and a customer display solves it neatly.
What to check in your software
Native IRP integration rather than an export-and-upload dance; IRN and QR printed on the thermal receipt; automatic cancellation within the permitted window; and a log you can hand to your CA.
Do not wait for the notice
Firms that switch after the threshold catches them spend a fortnight in a panic. Firms that switch before it treat it as a software setting. This is the cheapest compliance decision you will make.
