A beautiful interface, best templates in the business (recently made even MORE customisable) and fantastic customer support.
I love the fact that they have helpful hints everywhere, so you immediately find answers to whatever it is you don't manage to do. It's pretty straightforward and user friendly.
Now MoneyPenny saves me time and endless frustrations. The developers doing a great job and the CS is very friendly and helpful.
The only problem i have found is that there is no easy way to apply prepayments to a specific client. Payments can only be applied to invoices which is not ideal.
I worked 5 years now with some other tools and EXCEL. That gives me frustration over frustrations especially when I need to sum up tasks.
MoneyPenny automates everything so I no longer need multiple spreadsheets, user names, passwords, time-trackers or multiple apps I was using before.
