Host a portal where my users can sign up, select and change their products, input and change their credit card, see past statements, and generally manage their subscriptions & payment info.

I just want to be able to charge one off fees without the need for a subscription.

1) Provide a way so that my users have SSL pages on a subdomain of Chargify, such as https://myservice.chargify.com. 2) Provide SSL with a completely custom domain, such as https://secure.myservice.com

Push data to quickbooks for the bean counters. Pull clients from quickbooks would be nice too

Assume our customer can customize the look of this statement, such as with their logo

I'd like to be able to let a user subscribe to several products at the same time, and manage his or her subscriptions over the api.

When adding a new product to a users account, they should be billed immediately for the new product, but when it's time for reoccurring bill, the subscriptions should be prorated such that they only get billed once a month.

This, along with the 'product creation through api' would make chargify nearly perfect for me.

Allow configuration to send an email a few days before the users trial is to end.

Would like the ability when creating a subscription to ignore the trial of a product. This would be great when a customer has previously had a trial and we do not want to offer the trial again. Perhaps a simple flag in the Subscription API to bypass trial if product has one.

1) Provide a means for users to view past statements. 2) Provide a means for users to download past statements as nicely formatted PDFs.

Send a statement/invoice to my customer, but do NOT bill their credit card, do NOT do any dunning, I'll handle Accounts Receivable. Maybe provide an interface where I can mark accounts as paid, but that's a nice-to-have as long as I already have the invoices somehow (ie, copies emailed to me when they're sent out).

Your metering today allows customers to consume units and pay at the end of the month with.

I'd like to give our customers the ability to prepay for a number of units and then "consume" them until they run out.

It would be good to have the ability to be upfront with my customers and send them an email 2 days before payment is going to be taken.

I want my customer to be charged my setup fee only *after* they have received any trial time that I offer with their plan. This is really true if the trial is free. Sellers who offer non-free / lower-cost trials may not need this as much.

For testing purposes, it would be nice to be able to change the subscription state on demand (trialing, cancelled, active, etc) to make sure my app responds to them properly.

I realize this is by design, but it creates problems to not be able to delete customers and subscriptions. We had the same customer some how signup for the same subscription 4 times.

Push data to Xero (too) for the bean counters. Pulling customers from Xero would be nice too (too).

This is great for people signing up in the middle of their trial period. One would be able to specify the subscription start date in x-remaining-trial-days.

Allow logo and color change. Better yet, the ability to have the subdomain at a non-chargify.com domain.
