Monthly subscription / recurring payment

Hello, I could not find (maybe still does not exist for Litecart) the add-ons for a monthly subscription.
Explanation:
I sell 1 pack of dry algae (or fruit juice or anything else) for 10 usd.
Customers can buy it. I would like the customers to choose between buy it or subscribe to receive the same order once a month (till he will request cancellation).
Of course, I can create a separate product as a subscription but then I have to manually create the order once a month.
Is there a way to repeat the order automatically once a month? Like a recurring payment module.

Waiting for suggestions.
Thank you.

This functionality is not yet supported. It would require a separate payment flow.
I have no date for when this would be added. I need to get the next bigger milestone ready first.
I do like the idea of it.

Is there a public list of milestones? I'm interested in this as well.

No sorry, the amount of time needed to keep such a list updated made me prior the development instead.
It's a shame I know. I'm just trying to be as effective I possibly can by prioritizing.

If enough backers are interested in this. The sooner an add-on can be developed.
The most common cause for features not being developed is that no one want's to pay for it or there are not enough backers who simply only wanna pay the addon price. And without financers I simply prioritize other paid assignments instead.

What's the price?

The development cost for this could be maybe around 550-950 €.
It all depends on the details.

For subscriptions I assume you also want to automatically charge your customers on a monthly basis.
So you would also need an add-on or implementation for stored payment details and automatic payment methods.

@tim
Yes, need also implement with the payment gateway that could be Stripe and Paypal.
I am interest in this. Please note my interest is not an order yet... need to see the development of the project with the customer but would be a nice thing.

I'm also using Stripe and Paypal. I do not think that those payment methods need to create new orders for customers on a monthly basis as it is possible to make "subscription" products on Paypal and Stripe. They take care of the rebilling.

For those payment methods I think the only thing that needs to be added is the ability to "cancel" the previously purchased subscription product. The customer could cancel from Stripe or Paypal but the integration would be nice.

For a new payment method that I created (integrating with btcpayserver) I would like a new invoice created each month or year for each customer that previously paid. I would want those invoices emailed. I would also want a way for them to cancel. That's about it.

1. create and email an invoice for subscribed customers on a monthly/yearly basis.
2. allow customers to cancel.
3. (optional) allow customers to cancel recurring charges on Paypal and Stripe.

Ok so a Stripe and Paypal vendor specific subscription management tool. You would do monthly deliveries with yearly payments? I recommend creating an order each month for withdrawn stock items. But if the monthly part is automized by the payment service provider no such orders will be created.

When I think of this I think of the option in the cart or on the product page to enable subscriptions for some items to enable monthly repurchases of them. A page under the account to maintain them and how often to be charged for them. I would then create a monthly job to process all subscriptions. I feel payment is the hard part. Every payment service provider does something differently and that can be a problem. Some payments can be automatically charged, some require a payment link, and some setting them up as subscription services.

LiteCart's checkout should only be used for the first period's payment.

I think we are on the same page. The checkout should only be used for the first period's payment. Totally agreed.

That seems like a change to the Stripe add-on and Paypal add-on to allow for making a payment intent for an existing recurring product (on Stripe's/Paypal's end).

From there Litecart has nothing to do with it unless you give the customer the option to cancel from Litecart (this seems optional to me as they can cancel from Paypal or Stripe).

New payment method add-ons will need to come with their own job module. I'm writing a cryptocurrency-based job module. I intend for it to be freely available to anyone that wants it. Can I make a pull request for it so you can review it?

I'm still interested in paying for any modifications necessary to the Paypal and Stripe add-ons.

How would the checkout handle a mixed order of both single purchase items and subscriptions?

Do you have any thoughts or wireframes how to manage items with subscriptions?

My interest is to make it as useful as possible for most.

Hello,
people should be able, if possible, to handle mixed order.
Example: 1 bottle 10 eur and 1 cup (different article) every month = 12 eur/month. Total order: 10+12=22 eur, the next order will be automatically submitted (to Paypal? Stripe? 2checkout?) and automatically paid without the need of the customer to confirm it (as long as the subscription is not cancelled) and it will be 12 eur only as the subscription is for the cup only, not for the bottle.
Another useful option is this kind of discount:
1 cup 14 eur, 1 cup each month is 12 eur each month each cup.
Here an example: https://www.amazon.com/Nootropics-Focus-Neuro-Energy-Supplement/dp/B084CVJT68 probably you need a VPN from USA to see it. Anyway I attached the screenshot.
So the price of the setup including the synchronization with the payment gateway will be around 500 usd?

I agree with your assessment there in that people are getting used to subscription discounts. Not sure if that sort of thing can be implemented in a simple add-on (or series of add-ons) or if that is a fundamental change to the underlying system.

500usd would be a steal. 

I don't have much on wireframes. I am a developer but I'm still wrangling with restyling litecart to look the way I want it to.
I could work on creating a wireframe. It would be very specific to me, though.

I use plantuml as I like flat text. It probably won't be pretty but it will convey the idea.

As long as we can nail a concept for the backend to maintain these subscription offers. I appreciate a vast wireframe concept for the backend management.

E.g. Enable/disable
Discount amount
Frequency/Intervals
etc.
