Once someone purchases an extension, the marketplace sends us order and customer details. Some of our extensions used license keys that we needed to (1) generate and (2) send to customers ASAP.
As these marketplaces don't have any API we were literally keeping our eyes peeled for any new email in our company's inbox to manually generate and send the license (imagine this nightmare).
We tried out a couple of pretty expensive solutions ($500+/mo) but the result was not as good as we wanted. So we finally came up with our own internal solution that saved us hundreds of hours (and a lot of money). We are using it a couple of years already and finally launched it as a SaaS product so everyone can use it.
We don't have any special expectations about how helpful it will be to other people and businesses so we are still experementing and collecting user feedbacks. However, we have our first users coming (mostly) from Quora.
This is very motivating and we are working hard to make of Parsio.io a powerful email parser suitable for everyone.
We are actively collecting user feedbacks so we are open for discussion and advices.
Could this kind of tools be helpful for your business or project? What's the price you are ready to pay?
