[SOLVED] Promotions, Discount, CB Subs

Hello Team,

My client wants to use a discount voucher against CB Subs plan with recurring monthly payments. I have added the voucher in promotions, the discount of which is the same value as the monthly payment. Needless to say that when I tested the voucher it ended up as an error and did not complete. I am guessing this is because the value was reduced to 0.00 so nothing for the payment gateway to process.

Is there any way this can work? If not, is there any other way the client can use a voucher to give a free month when the plan is a monthly payment?

Many thanks
David

Most payment gateways do not allow $0 recurring subscriptions. You can only do $0 for the initial purchase for the majority of them.

Is there any way this can work? If not, is there any other way the client can use a voucher to give a free month when the plan is a monthly payment?

Yes, don't allow the promotion to apply to the recurring part of the plan. Only have it apply to initial payment. You can do this by setting "For Autorecurring payments subscriptions only: Second and following auto-recurring payments amounts" to "No" under the Advanced tab of your promotion.

Hi Kyle,

I had already tried that but I did notice that somehow I hadn't selected a plan. In the screenshot I have included all settings from that tab.

The subsequent test caused the same result - no error but did not complete.

Error
Submitted payment request didn't return an error but didn't complete. Please contact site administrator to check error log.

Summary
Art. Num. Item Price
Subscription Plan: 1 month for 3cellhosting £4.99 per one month
Sub-Total £4.99
One month free − £4.99, then £0.00
Total for first payment Free, then £4.99 per one month

Am I missing something?

Checked history and here is the error...

So it looks like there is an issue with Stripe when payment value is zero.

Kind regards

Have added a bug ticket to look into this further. Stripe does not support $0 recurring subscriptions, but it should ideally just put the Stripe subscription into a trial state and push the start date of the recurring amount. It does this already if you actually set an Initial Price/Duration for your plan, but looks like you just have a Regular Price/Duration and are discounting that which is trying to tell Stripe to create a $0 recurring subscription.

So a workaround is probably to use the following in your plan.

Is the first amount and period different: Different first period and price for Registration and Upgrade
First payment price of plan: 4.99
Initial validity duration: 1 month
Regular Price of plan: 4.99
Regular Validity duration: 1 month

That should allow your coupon to discount that first payment price without impacting the recurring part.

Hi Kyle,

OK, tried that but with same result.

Attached is screenshot of front end result.



The history log shows the same stripe error.

Here are the plan price settings...



Many thanks
David

Ok, I don't have any further workarounds to suggest at this time. I'll have to investigate this further (starting today) to see why that's happening.
