My clients love the invoices that And.co produces, mainly because of its "pay me" button that a lot of them find super convenient. It's the best freelancing productivity tool I've used so far.
It's ridiculously easy and seamless. Everything can be done in 5 clicks or less.
Since a lot of things are done for you, there isn't much room for customization, but it's a fair trade-off.
It was advertised as a free tool, and they just introduced a pro plan and limited all the features. :(
Was free for some time
UI/UX is messed up. Unstandard controls, strange navigation...
