 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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!

 Trustindex verifies that the original source of the review is Google. 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.
