Invio vs Solo
These are two different answers to two different questions. Solo is a tax and accounting app: it calculates live income tax, GST and ACC figures from connected bank accounts, with invoicing built in alongside. Invio is invoicing software at a flat monthly price, and leaves tax and bank data to you or your accountant. So the question is not which is better. It is whether you want live tax numbers and a bank feed, or the invoicing sharp.
We make Invio. Read our side with that in mind. Every statement about Solo below links to Solo's own published page.
