I absolutely loved using Solo for my business. As a small business owner, I'd much rather be out working with my clients than sitting behind a computer worrying about bookkeeping, GST and paperwork. Solo has made managing all of that so much easier and far less overwhelming. What I love most is how simple and intuitive it is. Linking my bank and IRD accounts means everything flows through automatically, so there are very few manual entries and far less time spent trying to keep on top of admin. I can quickly track income and expenses, keep an eye on GST, and see exactly where my business is at without needing to be an accountant. One of the biggest benefits for me has been cashflow planning. Being able to see what tax is due, when it's due, and having that information available at any time means there are no nasty surprises. It gives me confidence that I've set enough money aside and helps me make much better decisions about my business finances throughout the year. I also love that Solo is a New Zealand business built specifically with sole traders in mind. It understands the realities of running a small business here, and it feels like the app has been designed for people like me rather than trying to squeeze sole traders into software built for much larger companies. The support team have also been fantastic whenever I've had a question. They're friendly, responsive and genuinely helpful, which makes a big difference when you're running a business on your own. For me, Solo strikes the perfect balance between being professional and powerful enough to do what I need, while still being easy to understand and use day-to-day. It's become one of those tools that quietly works away in the background and makes running my business so much easier. I wouldn't hesitate to recommend Solo to other sole traders and small business owners. It's one of the best business tools I've invested in.

Absolutely loving using the Solo App!! I am a new user, after using an accountant over the last 3-4 years. Solo is very user friendly, and I wouldn't go back to using an accountant now. I can see clearly my income and expenses and the two times I have needed help, I have received help within minutes using the in-app chat line. Highly recommend!

Solo is great. It's turned-out to be a great solution for transitioning to my own business over the last few year. I've learned a lot in a process too. I also love the more straight-up and transparent subscription — just a monthly. Really helpful and responsive support too.

Just wanted to say thanks for making Solo! I've been doing my own accounts for years and get different things wrong every year. Love the simplicity and value of Solo, excellent support and development of new features. One less thing to worry about!

Common questions

Yes, you can use Solo with or without an accountant. Solo has been created from the ground up for beginners with no accounting knowledge to confidently manage their taxes, regardless of if they have an accountant.  We’ve also made it easy to share your Solo account with an accountant for additional support.

Solo is designed primarily for sole traders rather than companies. However, many people still use Solo to manage the accounting and tax of their registered limited company.
​
If you use Solo for your company there are a few limitations to be aware of. Such as, the income tax calculation in Solo is based on the personal income tax brackets rather than the company tax rate.

You don’t need to open or change bank accounts to use Solo. You can link your existing bank account/s and it doesn’t matter if you prefer to have a seperate business account, or have all your business and personal transactions mixed together.

You can connect as many banks and accounts as you need. Alternatively, you can also manually enter transactions into Solo or upload a transaction file from your bank.

Nope, the Solo subscription fee is all you’ll ever pay. There are no additional costs associated with using Solo. Regardless of how much you earn.

Solo was launched in early 2021 and has been continually improving ever since. We’re profitable, growing quickly and backed by a talented and dedicated local team who love what we do. You can read more about the early days of Solo on our blog.

Our approach to pricing is simple. We don’t raise prices on existing customers. That’s right, you will always be charged the price that you sign up at.

Solo doesn’t handle your money at any stage. Solo calculates your taxes, tax returns and shows you how much tax to put aside, but does not take the tax out of your income or make payments to IRD on your behalf.

You’re always in full control of money. So your tax money is always available if you need it in an emergency. You also have the option to earn bank interest on your tax until it become due, or park it on your mortgage account.

The best time to take control of your taxes is always now. You can start using Solo at any time during the financial year and Solo can also calculate tax for previous financial years.

We pride ourselves on providing unbeatable expert support from real and local humans. You can get in touch with us via Solo’s in-app chat or send us an email. We also provide phone or video calls on request to help you get set up.

Our support centre has a wide range of in-depth and practical help articles and videos covering every aspect of Solo. And if you’re new to self-employment, check out our popular beginners guide to self-employment on our blog.
