Recurring Billing Complexity
Founders and small teams struggle to manage recurring billing, failed payments, proration, and subscription tracking as they scale.
In their words
when you click the subscription button to add to the cart it will always only show the base price
I either go sign up for yet another service just for that one task, or I do it manually.
I've tried various apps in different combinations with each other and I can't find anything that correctly translates the add-on costs to the subscription charge.
Also dealing with deferred revenue recognition which our current setup just ignores completely, so that's a bonus pain point.
for me its auth and permission state, i keep rebuilding it. what id want on day one is one place that owns it
even simple changes like plan upgrades take days to process, and a lot of basic operations seem to require CSV workarounds
I have to implement rate limiting, RLS, handle migration files, create policies that enforce the correct payment flow and so much more.
he has to WhatsApp us at least 3 to 4 times just to get a single small UPI payment cleared
I want people to be able to visit the website and enable their subscription for weekly service, they can add their information, and pay to enable the service.
there is no auto debit for stablecoins the way there is with cards or ACH, so somebody has to physically go and initiate the transfer every single cycle
When a user subscribes to the site they get access to the first month of content, then for each month they maintain the subscription they get the next month
Adobe support was completely unwilling to help or hand over the account or to help us at all
thinking of all the transaction fees to every service I’d pay for…
Bluesky
cancellation happens in the UPI app itself I don't have to faff around in the SaaS and deal with potentially some dark patterns.

Where they talk
- r/SaaS
- r/SideProject
- r/micro_saas
- r/microsaas

Tools they use today
- Stripe
- Shopify
- Lemon Squeezy
- RevenueCat
- Paddle
- PaymentKit
- Seal Subscriptions
- Supabase
Why those fall short
- models get payment flows wrong; each project rediscovers the boring layer
- competitors offer free/freemium countdowns, so charging per countdown pushes users away
- Stripe cannot handle complex proration and mid-cycle upgrades cleanly
- 1% of gross grows with scale; data locked in vendor schema; dashboard poor
- webhooks arrive out of order and overwrite correct subscription state
