Pros: Great idea, if it would only work as advertised. It's been an expensive experience, both financially and time wasted.

Cons: Expensive, so you'd expect quality performance and support. You'll be disappointed. I could never get the supposed integration with Freshbooks to work, and support was mindless and ineffective. I had to export the receipts to a google drive and manually enter them into Freshbooks, in order to get any usefulness from my one monthly subscription payment.

The worst part, was they upgraded me to an annual subscription without my consent, and their promised refund never showed. They they proceeded to make repeated attempts to charge my card for even more expensice annual subscriptions, claiming I had clicked a button to request this. (As if!) Fortunately, after the first charge, I changed my payment method to a card that wouldn't clear their expensive charges. (They don't give you the option to remove payment methods completely.)

Repeated chat complaints were ignored.

Overall: A royal pain, with very limited value received for an expensive product. Maybe you'll be lucky and get the promised value. I can only assume it sometimes works as advertised.
