👋 give me a minute to check on one thing - I think you would be able to model it with a single subscription that has a one-time item added in the first invoice, but I want to double check

[earnest flax]

Thank you! I should note that this would be a recurring yearly subscription. So every year we would re-charge them the base fee

[violet idol]

Ah, right I forgot that the fixed fee is annual

[earnest flax]

Ya so basically we charge them annually for 5000 events, and anything they use over that during the year, we would charge them monthly for

[violet idol]

Yeah using two subscriptions certainly works (but it's tricky since you have to keep them in sync). The only other way I can think of doing this is:

• create the subscription w/ the monthly price + a one-off invoice item for the annual fee
• when you create the subscription add metadata that tells you when the annual fee should be charged next
• have a webhook listener that listens for customer.subscription.updated to get the renewal events and check the metadata. If it's time to charge for the annual fee again, add the invoice item

[earnest flax]

Ya that's in line with what we were thinking too

Things like cancellations get a bit tricky because if they cancel, we would want the subscription to end at the end of the year and not the end of the month

[violet idol]

Yeah you'll have issues with both of these options really (for 2 subscription you need the logic to keep the two subs synced together and canceled at the same time, and with metadata you need extra logic to process it)

[earnest flax]

I'm going to try and convince stakeholders to use a threshold based approach instead. I think that would solve our problems

Thanks for the help!
