I spent the last couple of months of 2018 completing a new app called Pocket Invoicer. I noticed that Estimate Maker was quite successful, and enhancing it enough to make it handle invoices was quite easy, and always the plan. I wanted it to be out in the wild to be sure I had no major bugs before adding what would be more crucial functionality.
Unfortunately, invoicing has more competition than estimating, and my little invoicing app is not doing very well. I’m going to drop the price on it yet again to see if I can’t get it to be at least as successful as Estimate Maker. I tried changing the name to ‘Invoice in your pocket’ to see if it was the fact that invoice isn’t in the name that was causing it to rank so poorly in search. But that did not help.
