eInvoicing Explained: Get Paid Faster and Dodge Invoice Scams

Most Australian businesses still think emailing a PDF invoice counts as electronic invoicing. It doesn't — and that misunderstanding is costing you money, slowing down your payments and leaving the door wide open to one of the nastiest scams going around. Here's what eInvoicing actually is, why it's worth ten minutes of your time, and how to switch it on in the software you already use.

What eInvoicing actually is (and isn't)

eInvoicing is the exchange of invoice data directly between two accounting systems. When you send an eInvoice, your software packages up the invoice as structured data — ABNs, line items, amounts, due date — and delivers it straight into your customer's accounting software, where it lands as a ready-to-approve bill. No PDF, no email, no one retyping numbers at the other end.

The delivery happens over the Peppol network, an international framework the Australian and New Zealand governments adopted as the standard. Think of Peppol as a telephone network for invoicing. You don't care what brand of phone the other person owns — if you're both connected, the call goes through. Same here: you might use Xero and your customer might use MYOB or SAP, but because both systems are plugged into Peppol, the invoice arrives perfectly formatted either way. The ATO runs the Australian end as the local Peppol Authority, but it can't see your invoices — the network just routes them, addressed by ABN.

What eInvoicing is not: a PDF attached to an email. A PDF is just a picture of an invoice. Someone still has to open it, read it, key it into their system and hope they didn't fat-finger a digit. Every one of those steps costs time and creates a place for mistakes — or fraud — to creep in.

Why bother: the numbers

The ATO's research on invoice processing costs is blunt. Between printing, posting, keying, chasing and fixing errors, a paper invoice costs around $30 to process end to end, and an emailed PDF isn't much better at around $27. An eInvoice comes in at under $10.

How the invoice arrives	Typical cost to process (ATO research)
Paper	around $30
Emailed PDF	around $27
eInvoice	under $10

If you only send a handful of invoices a month, that's nice but not life-changing. Send or receive a few hundred and the savings get serious — and that's before you count the soft benefits: invoices can't go to spam, can't sit unopened in someone's inbox for a fortnight, and arrive as a draft bill the customer can approve in two clicks. Less friction between "invoice sent" and "invoice paid" is exactly what your cash flow needs.

There's a hard payment-speed incentive too if you sell to the Commonwealth. Under the government's Supplier Pay On-Time or Pay Interest policy, federal agencies must pay correctly rendered invoices on contracts up to $1 million within 20 calendar days — but where both sides use Peppol eInvoicing, that maximum drops to 5 calendar days. Miss the deadline and the agency has to pay you interest (where the amount accrued is over $100). Five-day payment terms, backed by an interest penalty, is about as good as payment terms get in this country.

The big one: eInvoicing kills invoice interception scams

Here's the part that should get your attention even if you couldn't care less about processing costs.

Payment redirection scams (also called business email compromise) work like this: a scammer gets into an email account — yours, your supplier's, or somewhere in between. They wait and watch. When a genuine invoice goes out as a PDF, they intercept it, change the BSB and account number, and send it on. Everything else about the invoice is real, so the customer pays without blinking — straight into the scammer's account. By the time anyone notices, the money's gone, and you're stuck in an ugly argument about who wears the loss.

This isn't a fringe problem. The National Anti-Scam Centre's figures for 2025 show Australians reported $2.18 billion in total scam losses, with payment redirection scams accounting for $166.8 million of it — one of the top five loss categories, and the one that hits businesses hardest. Real estate, construction, legal and trades businesses are favourite targets because they routinely send big invoices.

eInvoicing shuts this scam down at the structural level. The invoice never travels through email, so there's nothing sitting in an inbox to intercept and doctor. It moves software-to-software through accredited access points on the Peppol network, addressed to your customer's ABN. There's no PDF to tamper with and no human transcribing bank details from an attachment.

One honest caveat: eInvoicing stops invoice interception, but it doesn't vet the sender's character. A scammer with a genuine ABN could still send you a fake bill, and if a supplier says their bank details have changed, still verify it by phone on a number you already have. eInvoicing removes the biggest attack surface; it doesn't replace basic scepticism.

Where government adoption is at in 2026

The government has been pushing eInvoicing hard for a few years, and 2026 is when the screws tighten:

Commonwealth agencies — all non-corporate Commonwealth entities have been required to be able to receive Peppol eInvoices since 1 July 2022. The current policy goes further: eInvoicing is being made the default for federal procurement, agencies are expected to have at least 30% of the invoices they receive coming through the Peppol network from 1 July 2026, and to be able to send eInvoices by December 2026.
NSW — state agencies have been required to be able to receive eInvoices since 1 January 2022, and NSW remains the most advanced state on adoption.
Other states and territories — South Australia, Victoria, Tasmania and the ACT have enabled eInvoicing across various agencies without hard mandates, and hundreds of state bodies and local councils are now on the network.
Business-to-business — still voluntary. Treasury consulted back in 2021–22 on a "Business eInvoicing Right" that would have let a Peppol-enabled business legally require its trading partners to send eInvoices, but no legislation has come of it (as at August 2026). Don't wait for a mandate to force your hand — the practical benefits stand on their own, and if a B2B requirement does eventually land, you'll already be sorted.

The plain-English takeaway: if you sell to government, eInvoicing is rapidly becoming the expected way to bill them — and it gets you the 5-day payment terms. If you sell to other businesses, it's optional but increasingly common, especially among bigger customers.

How to switch it on

Here's the good news: if you use one of the major accounting packages, the hard work is already done. Peppol is built in — you just have to register, which takes minutes. (If you're still choosing software, our accounting software comparison covers the main players.)

Xero

Check your ABN is entered correctly in Settings → Organisation details.
Go to Business → Bills to pay, click Receive eInvoices, then Register to receive eInvoices and follow the prompts.
To send, raise an invoice as normal — if your customer's ABN is registered on the Peppol network, Xero gives you the option to send it as an eInvoice instead of (or as well as) email.

MYOB

Click the settings (gear) menu → Sales settings, then open the eInvoicing tab.
Follow the registration steps to confirm your ABN and business details. MYOB's eInvoicing runs through its partner access point and is free to set up.
Once registered, you can send eInvoices from the invoice screen, and incoming eInvoices from suppliers land in your software ready to code and approve.

QuickBooks Online

QuickBooks doesn't have Peppol registration baked into its Australian settings the way Xero and MYOB do. Instead, you connect an ATO-accredited Peppol service provider (an "access point") that integrates with QuickBooks — providers like LinkFor, LUCA Plus, MessageXchange and Storecove all play in this space, and some have free or cheap entry tiers. The ATO publishes a register of accredited eInvoicing providers on ato.gov.au, which is the safest place to pick from.

Whichever platform you're on, if the setup screens aren't your idea of fun, this is a five-minute job for your bookkeeper or BAS agent — ask them to register you next time they're in your file.

What it costs

For most small businesses: nothing extra. Sending and receiving eInvoices in Xero and MYOB is included in your existing subscription — no per-invoice network fee at typical small business volumes, no new hardware, no separate contract with Peppol. Your software provider (or accredited access point) handles the plumbing. QuickBooks users may pay a small amount for a third-party access point depending on the provider and volume, but free tiers exist. Compared with what you're currently spending in staff time pushing PDFs around, it's one of the rare genuine free lunches in business admin.

Should you switch now or wait?

Switch now if you:

Sell to Commonwealth or NSW government agencies — 5-day payment terms are the fastest money in the country, and agencies increasingly expect it.
Send or receive a decent volume of B2B invoices — the time savings compound quickly.
Have ever been targeted (or burnt) by a payment redirection scam, or handle invoices big enough that one intercepted payment would really hurt.
Already use Xero or MYOB — it's free and takes ten minutes, so there's no real reason not to register to receive even if you keep emailing invoices to customers who aren't on the network yet.

Fair reasons to wait:

You invoice consumers, not businesses. Peppol is a business-to-business and business-to-government network — your retail customers can't receive eInvoices, so email and payment links remain the right tools there.
You have a tiny number of B2B customers and none of them are registered yet. You can send an eInvoice only to a business that's on the network, so check with your regular customers — although registering to receive costs you nothing in the meantime.

Either way, eInvoicing runs happily alongside your existing invoicing. It's not a switch you flip for every customer at once; your software simply uses Peppol where it can and email where it must. Registering doesn't change your GST or BAS obligations — it just means cleaner data flowing into them.

Key takeaways

eInvoicing sends structured invoice data software-to-software over the Peppol network — think of it as a telephone network for invoicing. An emailed PDF is not an eInvoice.
ATO research puts the cost of processing a paper invoice at around $30 and a PDF at around $27, versus under $10 for an eInvoice.
Because eInvoices never pass through email, they can't be intercepted and doctored — payment redirection scams cost Australians $166.8 million in 2025 alone.
Commonwealth agencies pay eInvoices on contracts up to $1 million within 5 days or pay you interest; from 1 July 2026 federal agencies are expected to receive at least 30% of invoices via Peppol.
eInvoicing is built into Xero and MYOB and free to switch on; QuickBooks users connect via an ATO-accredited access point.
B2B eInvoicing remains voluntary (as at August 2026) — but if you use Xero or MYOB there's little reason not to register now.
