Xero to Odoo Migration: What Moves, What Stays Behind, and When to Cut Over
Moving from Xero to Odoo? Here's what data comes across, what stays in Xero, how opening balances work, and the best cutover timing for Australian businesses.
By Josh Craig, Director, Auboros ·
Deciding to leave Xero usually takes months. The migration itself takes weeks, and most of the anxiety in between comes from one question: what actually happens to my data? It’s a fair thing to worry about. Your Xero file holds years of invoices, bills, payroll records and BAS history, and the idea of moving all of that into a new system sounds risky.
Here’s the part that surprises most people: a good Xero to Odoo migration moves far less data than you’d expect. The skill isn’t in dragging everything across. It’s in knowing what to bring, what to leave behind, and where to draw the line in time. This post walks through exactly that, based on the migrations we run for Australian businesses.
What moves in a Xero to Odoo migration
Three categories of data come across in almost every migration. Each one is exported from Xero, cleaned up, and loaded into Odoo using its standard import tools, which accept CSV and Excel files for pretty much any record type.
Master data: contacts, accounts, and products
Customers, suppliers, your chart of accounts, and your product or service list form the foundation. This is also the best data-cleaning opportunity you’ll ever get. Every Xero file we’ve migrated carries duplicate contacts, dead accounts, and products nobody has sold in years. Migrate the mess and you’ve just paid to move rubbish into a new house.
The chart of accounts deserves particular care in Australia. Odoo’s Australian localisation ships with a local chart of accounts and GST tax codes already configured, so the job is mapping your Xero account codes onto it rather than rebuilding from scratch. Getting the tax mapping right here is what keeps your first Business Activity Statement (BAS) out of Odoo clean.
Open items: what’s still in flight
Unpaid customer invoices, unpaid supplier bills, and outstanding credit notes come across as individual records. They have to, because you’ll be receipting payments against them in Odoo. Anything already paid and settled stays behind as history.
Opening balances: the line in time
Everything else arrives as one journal entry. You run a trial balance in Xero dated the day before cutover, and that becomes an opening balance journal in Odoo: every asset, liability and equity account, matched to the cent. From that date forward, Odoo is the system of record. This single entry is where migrations succeed or quietly fail, which is why it gets reconciled against Xero before anyone processes a live transaction.
What stays behind, and what to do about it
Historical transactions generally don’t move. Five years of paid invoices and old bank reconciliations add little day-to-day value inside Odoo, and importing them properly costs real money. But you can’t just delete them either. The Australian Taxation Office requires most business records to be kept for five years, and some company and employee records for longer.
You have three practical options, and most businesses use a combination:
- Keep the Xero subscription on a reduced plan for a year or two as a read-only reference, then export and cancel.
- Export everything to files: reports, transaction listings and attachments saved to storage you control. Cheapest long-term, slightly clunkier when an auditor asks a question.
- Import summary history into Odoo, such as monthly journal totals for the prior year or two, so year-on-year reporting works without importing every document.
A few things need re-establishing rather than migrating. Bank feeds don’t transfer, so you’ll connect your bank to Odoo fresh and set a clean statement starting point. Payroll is its own workstream: employee records, leave balances and year-to-date figures need careful setup in whichever payroll arrangement you land on, and Single Touch Payroll (STP) reporting continues without gaps. If you’re weighing up the connector route instead of a full migration, we’ve covered what an Odoo Xero integration actually syncs separately, and third-party connectors on the Odoo app store can bridge the two systems during a transition.
When should you cut over from Xero to Odoo?
The textbook answer is 1 July. Starting a new financial year in a new system means one clean set of books per year, one system per tax return, and an opening balance that matches your closing audited position. If you’re reading this in July or August having just missed that window, you have not missed your chance.
The start of any BAS quarter works nearly as well. For most Australian businesses that means 1 October, 1 January or 1 April. Cutting over on a quarter boundary means each BAS is prepared from a single system, which your bookkeeper will thank you for. Mid-quarter cutovers are possible, but someone ends up stitching two systems together for one lodgement, and that’s an avoidable headache.
There’s also a staged path. Plenty of businesses stand up Odoo for operations first, keep Xero running the books, and move accounting across a quarter or two later. We’ve written about running Odoo and Xero together, and it’s a legitimate transition strategy rather than a failure to commit. The trap is treating it as permanent when it was meant to be a bridge.
“The migrations that go wrong are almost never a technology problem. Someone decides they want five years of transaction history recreated in Odoo, the project drags for months chasing perfect history, and meanwhile nobody has agreed what the opening balance is. Flip the priorities. Nail the opening balance, bring the open invoices, keep Xero as your archive, and you’re live in weeks with books you can trust.”

How long does the migration take?
The data migration itself is typically two to four weeks of elapsed time inside a broader implementation: extract and clean, trial import into a test database, verify, then the final cutover run. The wider project around it, configuring modules, training people and testing workflows, is what sets the overall timeline, and we’ve broken that down in our Odoo implementation guide for Australian businesses.
The single biggest factor you control is data quality. A business that spends a fortnight cleaning contacts and products in Xero before extraction will migrate faster and cheaper than one that hands over the file as-is. The trial import matters just as much: you want every surprise to happen in the test database, not on go-live weekend.
When staying on Xero is the right call
Honesty time. If Xero still fits, keep it. A business with straightforward invoicing, no inventory, a single entity and no operational sprawl doesn’t need an ERP, and Xero itself now markets higher tiers aimed at growing businesses to stretch that ceiling further. The move to Odoo makes sense when the pressure is operational: stock in multiple locations, manufacturing, field teams, multiple entities, or a stack of disconnected apps taped around the accounting file. We’ve set out the signals in detail in our guide on when to upgrade from Xero to an ERP. If those signals aren’t flashing yet, a migration buys you complexity you don’t need.

FAQ
Frequently asked questions
How long does a Xero to Odoo migration take?
The data migration itself usually takes two to four weeks: extraction, cleaning, a trial import, verification, then final cutover. It sits inside a broader Odoo implementation, which for most Australian small and mid-sized businesses runs eight to sixteen weeks depending on scope.
Can I import my Xero transaction history into Odoo?
You can, but most businesses shouldn't import all of it. Standard practice is to bring master data, open invoices and bills, and opening balances, with monthly summary journals if you want prior-year comparatives. Full line-by-line history is expensive to migrate correctly and rarely worth it.
Do I lose my Xero data after migrating to Odoo?
No, and you're required to keep it. The ATO's record-keeping rules mean most business records must be retained for five years. Businesses typically keep Xero on a reduced plan as a read-only archive for a period, export complete reports and attachments to their own storage, or both.
Can I run Xero and Odoo at the same time during the transition?
Yes. A common staged approach runs Odoo for operations while Xero keeps the books, connected by an integration, with accounting moving across at a quarter boundary later. It works well as a bridge, though running both permanently means ongoing double-handling and reconciliation overhead.
