Pretty good, with room to grow.
Overall this app does what I need to do — just create simple PDF invoices for my independent contractor IT work. But there’s a lot of room for improvement in the usability department. For example, the ability to rearrange line items would hugely convenient. Also would be nice if the developer made it a little more clear how to get the PDF out of the app — as is you can just drag it out of the little preview pane and onto the desktop, but this wouldn’t be terribly obvious for a novice user. Finally, a little more spacing (or the ability to customize the design, or at least bolding the title of each line item) on the generated PDF invoice would go a long way; currently I find myself adding a line of underscores in the description of each line item to keep them more visually separated on the final product.
Overall, it works and is a viable replacement for Billings in my world. But I hope they bring some usability improvements in later versions. The only feature I’m missing is Billings’ built-in timeclock.
