Xero for NZ Landlords: Syncing Your Rental to Your Accountant

I will start with the honest part, because it matters and because someone always asks. I do not use Xero for my own four rentals. My accounting is simple. A handful of properties, rent in, a known set of expenses out, one annual chat with a person who knows the tax rules better than I do. A spreadsheet handled it for years, and then RentManager handled it.

So why did I build a Xero integration into RentManager? Because most landlords are not me. Most landlords with a few properties have an accountant, and in New Zealand that accountant almost certainly works in Xero. If you have an accountant, the question is not really "do I want Xero". The question is "how do I get my rental numbers into Xero without re-typing them, or worse, without handing over a folder of receipts in July".

That is the job this feature does. This article explains what it syncs, how it works, and where it honestly sits today.

Why a property tool should talk to Xero

A landlord's year produces a steady trickle of accounting events. Rent arrives, ideally on time. Rates and insurance go out. A hot water cylinder fails and a plumber sends an invoice. An inspection turns up a small repair. None of it is complicated on its own. The problem is the gap between where those events happen (your bank account, your property tool, your inbox) and where they need to land (your accountant's Xero file).

Most landlords bridge that gap with effort. They keep a shoebox, or a spreadsheet, or a shared folder, and at the end of the financial year they hand it over and the accountant re-keys it. You pay for that re-keying. It is slow, and it is the part of the process where numbers get dropped or mis-coded.

The point of an integration is to delete that gap. If your property tool already knows a rent payment happened, it should be the thing that tells Xero. You should not be the courier.

What syncs into Xero

RentManager pushes three kinds of record into your connected Xero organisation, automatically, as you work:

Rent payments become invoices

When you match a rent payment in RentManager - whether it came in through bank sync or you matched it by hand - that payment is pushed to Xero as a sales invoice, already marked paid, against the right tenant and property. Residential rent is synced GST-free, which is how the IRD treats it, so you are not creating a GST headache that is not really there.

Expenses become bills

Every expense you record - rates, insurance, repairs, maintenance, management fees if you use a manager - becomes a bill in Xero. The category you chose in RentManager travels with it, so the expense is already coded in a way that lines up with how rental income and expenditure is reported on an IR3R.

Tenants become contacts

Add a tenant in RentManager and they show up as a contact in Xero. That is the small plumbing detail that makes the rest work: an invoice needs a contact to belong to.

It goes both ways

A sync that only pushes is half a feature. RentManager also listens.

When an invoice is marked paid inside Xero, RentManager hears about it through a webhook and records the payment on its side, so the two systems do not drift apart. And supplier bills that arrive in your Xero inbox - including Peppol e-invoices, which are becoming normal for NZ trades - are matched back against your tradies and turned into expenses in RentManager. So a plumber's e-invoice can become a tracked, categorised property expense without you copying a single figure.

Under the hood it is built to the standard Xero expects of a serious integration: OAuth 2.0 (RentManager never sees your Xero password), signed webhooks so a fake "invoice paid" message cannot sneak in, idempotency so nothing double-posts, and automatic retries if Xero is briefly busy. I mention that not to show off the plumbing, but because an accounting sync that quietly gets it wrong is worse than no sync at all.

How you turn it on

Inside RentManager, open Accounting, choose Xero, and sign in to your Xero organisation. That is the whole setup. From that point the sync runs on its own. There is no "sync now" button to remember - new payments and expenses reach Xero within seconds of you entering them.

If you want the visual version of all this, the Xero integration page has a plain summary of what connects to what.

The honest status

Three things worth saying plainly, because I would want them said to me.

It is on the Standard plan and above. The Xero sync is not part of the entry-level Starter plan. If you have enough properties to be thinking about Xero, you are almost certainly on Standard or higher already, but it is worth knowing.

We are not on the Xero App Store yet. Listing an app on the Xero marketplace carries a monthly fee that only makes sense once enough landlords are connected to cover it. We are not there yet, so for now you connect from inside RentManager directly rather than finding us in the Xero store. The integration itself is fully live - the marketplace listing is a separate marketing step, not a measure of whether the feature works.

It is genuinely uncommon. There is not a lot of New Zealand-built rental software, and what exists tends to offer an import-only link, or none at all. A live, two-way sync built specifically around NZ residential tenancy rules is rare. I am not going to pretend that is a permanent moat, but it is true today.

If you do not use Xero

Then you do not need any of this, and that is fine. RentManager produces its own income and expense reports, and a tidy annual summary, and plenty of landlords (me included) hand that straight to their accountant or their own IR3R without Xero in the loop. If you want the wider picture of how the numbers side works, I wrote a separate piece on landlord accounting software in NZ.

The Xero integration exists for the landlords whose accountant has already told them which tool to use. For them, this removes the most tedious, most error-prone hour of the rental year. That seemed worth building, even for someone who does not use Xero himself.

If that is you, you can start a free RentManager trial and have Xero connected a minute later.
