The short answer
Xero has a more developer-friendly API and connects more easily to Power BI, Power Query, and modern automation tools. Sage — particularly Sage 50 — is more widely used by UK accountants but its data is harder to extract automatically. If automated reporting is a priority, Xero has the edge. If you are already on Sage, switching is rarely worth the disruption — the connection can still be built, it just requires more work.
This question comes up regularly when I am working with UK businesses on their reporting. They are either choosing between the two for the first time, or they are already on one and wondering whether the other would make their data life easier. The honest answer is that the choice of accounting software matters less than most people think — and what matters far more is how well the connection to your reporting tools is built.
That said, Xero and Sage are genuinely different when it comes to data accessibility. Here is what those differences look like in practice.
How each platform handles data access
The practical difference for UK businesses
In practice, the difference comes down to how much technical work is required to get your financial data flowing automatically into your reporting tools.
With Xero, connecting to Power BI or Power Query requires setting up OAuth authentication and building the API queries — but the process is well-documented, widely supported, and relatively straightforward for someone with the right technical knowledge. We covered this in detail in our guide to connecting Xero to Excel.
With Sage 50 desktop, the data sits in a proprietary Pervasive database. You can access it via ODBC — which means writing SQL queries directly against the database — or via the Sage API, which has more limited coverage than Xero. It is workable but requires more technical knowledge and more careful handling of the data structure. Sage Business Cloud is significantly closer to Xero in terms of API accessibility.
Connecting to Power BI — the key comparison
Power BI is the most common destination when businesses want a live financial dashboard. Here is how the two platforms compare specifically for Power BI integration:
| Factor | Xero | Sage |
|---|---|---|
| Native Power BI connector | Yes — available in marketplace | Yes — but less comprehensive |
| API quality | Modern REST API, well documented | Sage 50: ODBC/legacy. Business Cloud: modern API |
| Ease of connection | Straightforward with technical knowledge | Sage 50: complex. Business Cloud: easier |
| Data refresh | Scheduled refresh works reliably | Works but requires more configuration |
| Third-party connectors | Large ecosystem, well supported | Fewer options, less community support |
| MTD compatibility | Built-in MTD submission | MTD supported across product range |
| UK accountant familiarity | Very high — widely adopted | Very high — long-established in UK |
Should you switch from Sage to Xero for better reporting?
This is the question I get asked most often — and my honest answer is almost always no, not primarily for reporting reasons.
Switching accounting software is a significant project. It involves migrating historical data, retraining your team and accountant, potential disruption to your financial processes, and a period of running two systems in parallel. The cost and disruption almost never makes sense just to get a better API connection.
A properly built Sage connection — via ODBC for Sage 50 or the API for Sage Business Cloud — will give you the same automated reporting outcomes as a Xero connection. It requires more technical work upfront, but the end result is the same: financial data flowing automatically into your Excel models or Power BI dashboards, refreshing on a schedule, without anyone exporting manually.
The exception is if you are choosing for the first time and automated reporting is a key priority from the start. In that case, Xero is the easier path — not because Sage cannot be made to work, but because the initial setup is less complex and the ongoing maintenance is simpler.
The honest verdict
Frequently asked questions
Can Sage connect to Power BI?
Yes. There is a native Sage connector available in the Power BI marketplace. For Sage 50 desktop, you can also connect via ODBC, which allows Power BI to query the Sage database directly. The native connector is more straightforward; the ODBC route gives more flexibility but requires more technical knowledge to set up correctly.
Can Sage data be pulled into Excel automatically?
Yes — via Power Query using either the Sage API or an ODBC connection for Sage 50. Once the connection is set up, Excel can pull your Sage data automatically on refresh, without any manual exports required. The setup is more complex than Xero but the outcome is the same.
Does Xero work with Making Tax Digital?
Yes. Xero is a fully MTD-compatible software and handles quarterly digital submissions directly. Sage is also MTD-compatible across its product range. For MTD specifically, both platforms are equally capable.
Which is better for a small UK business — Sage or Xero?
For most small UK businesses, Xero is the more modern and user-friendly choice, with better app integrations and a cleaner interface. Sage 50 has a long history in UK accounting and many accountants are deeply familiar with it — which has value. The right choice depends on your accountant preferences, the complexity of your accounting needs, and how important direct system integrations are to you.
I use QuickBooks — does the same apply?
QuickBooks Online has a modern API similar to Xero and connects well to Power BI, Power Query, and Excel automation tools. The same general principles apply — the connection can be built to automate your reporting in the same way as Xero or Sage Business Cloud.
