I really enjoy the pay by invoice feature. My clients love the secure pay option. It saves me time so I don't have to stand at a doorstep while the customer finds cash. I can send them the invoice and head out to the next job.
I feel like it makes my job a lot easier. Keeping track of who owes what and how and what they paid. The route tool makes it where a lot of the aspects of the job are almost on autopilot.
I have been using it for about 3 months now, going from pen and paper and manually typing up invoices it's a huge time saver when it comes to collecting payments and keeping records.
