Saasybill vs Chargebee: Which One Is Right for Your SaaS Business?
Chargebee is a capable product built for a specific kind of company. If you're a small-to-mid SaaS business on Xero, it's probably not the right fit. Here's an honest look at the difference.
If you're looking at billing tools for your SaaS business, Chargebee will come up quickly. It's one of the more established names in the space, it has a long feature list, and it handles subscription complexity reasonably well. For a certain kind of company, it's a good product.
But "established" and "right for you" aren't the same thing. Chargebee is built for a specific scale and a specific set of assumptions, and if your business doesn't match those assumptions, you'll pay for features you don't need and create problems you didn't have.
Here's what the actual comparison looks like.
What Chargebee does
Chargebee is a full billing platform. It handles subscription management, invoicing, revenue recognition, dunning, multi-currency, tax compliance, and integrations with a long list of payment gateways. It's designed for companies with complex billing requirements, global operations, and dedicated finance teams who can manage the implementation and ongoing configuration.
It integrates with Xero, but the integration works in one direction: Chargebee runs your invoicing, and it pushes summary data back to Xero. Your invoicing lives in Chargebee, not in Xero.
What that means in practice
If you're currently running your invoicing through Xero, switching to Chargebee means your revenue data moves out of Xero and into Chargebee's system. Xero becomes a downstream recipient of data rather than the source of truth. What comes back to Xero is usually summarised, not itemised, which means your Xero reporting stops reflecting the full picture of what's happening in the business.
For your accountant, this matters. They work in Xero. If the data in Xero is incomplete or aggregated in a way that doesn't match the underlying transactions, reconciliation becomes harder and the reporting they rely on becomes less reliable. You've solved a billing problem and created an accounting problem.
Then there's the cost. Chargebee's Starter plan is free up to AUD 350K of cumulative billing, then 0.75% on everything after that. At $30K/month in billing, that's $225/month going to Chargebee on top of whatever else you're paying. The Performance plan removes the percentage and moves to a flat AUD $9,588/year, billed as a monthly commitment, but it caps your billing volume at AUD $130K/month. Beyond that you're on Enterprise pricing, which means talking to sales before you know what you'll pay. For a tool whose core job is generating invoices, that's a meaningful cost at every stage.
Where Chargebee makes sense
None of this is a criticism of Chargebee as a product. It makes sense for companies that have genuinely outgrown Xero as a billing system, are operating in multiple countries with complex tax requirements, and have the team and budget to support it. If you're at that scale, Chargebee is worth evaluating seriously.
If you're a B2B SaaS company with 20 to 300 customers on a small number of plans, mostly in one or two countries, and you're using Xero as your accounting system, Chargebee is almost certainly more than you need and the trade-offs don't work in your favour.
What Saasybill does differently
Saasybill is not a full billing platform. It's a billing layer that sits on top of Xero and handles the subscription logic that Xero doesn't do natively.
You define your pricing plans, attach subscriptions to customers, and Saasybill handles the rest. At each renewal, the invoice is created directly inside Xero. Proration when someone changes plans, credit notes, mid-cycle adjustments: all of it lands in Xero as proper invoices, the same way they would if you'd created them manually. Your accountant sees exactly what's happened, in the system they already use, without any extra steps.
Xero stays as the source of truth. There's no data sync to manage, no summarised journal entries to reconcile, and no revenue data living in a third-party system.
There are no transaction fees. Saasybill charges a flat monthly subscription and nothing else, regardless of how much you bill through it.
The honest comparison
| Saasybill | Chargebee | |
|---|---|---|
| Invoicing lives in | Xero | Chargebee |
| Xero data | Complete, itemised | Summarised sync |
| Transaction fees | None | 0.75% on Starter after free tier |
| Setup complexity | Low | Medium to high |
| Best for | 20 to 300 customers on Xero | High volume, complex or global billing |
| Pricing model | Flat subscription | % of revenue or AUD $9,588/yr + cap |
Which one to choose
Most small-to-mid SaaS companies on Xero are paying for complexity they don't have and giving up accounting clarity they do need. The 0.75% transaction fee compounds quietly on Starter, and the Performance plan at AUD $9,588/year is a significant recurring cost for a company that mostly needs invoices generated on time and reconciled correctly in Xero.
Chargebee does things Saasybill doesn't: multi-entity support, on-demand discounting, contract terms, global tax handling. If those are genuinely part of how your business operates, it's worth evaluating. But if what you actually need is reliable subscription billing that keeps Xero accurate and your accountant out of spreadsheets, paying AUD $9,588 a year for features you'll never touch is just overhead.
