Hummingbird Recurring Billing

gistfile1.txt

Here's how it's going to look like from the end user perspective:

1 hour before my PRO membership ends, if I am on a recurring plan 
Hummingbird will try to charge my credit card. If it succeeds 
everything is good. If it fails my subscription will run out and 
Hummingbird will try to charge my credit card again tomorrow, 3 
days from now and 5 days from now. I will receive an email from 
Hummingbird if the charge is successful, and a different email 
every time charging my card fails.

If I am not on a recurring plan I will get an email 1 day before 
my subscription runs out urging me to get on a recurring plan.

From an implementation point of view:

We will be adding Sidetiq for recurring jobs. There will be a 
number of jobs to handle this logic.

1. Hourly job that extends the subscription of every user whose
subscription runs out in the next hour.
2. Daily job that will handle credit card processing failure. It 
will pick up users whose subscription ran out 1 day ago, 3 days 
ago and 5 days ago.
3. Daily job that sends an email to all PRO members who are not 
on a recurring plan, and whose subscription runs out in the next 
24 hours.

Looks good, I still sort of feel like we should be relying on Stripe for this however.
