Cheap Recurring Payments with Stripe and AWS Lambda
- PaulRobinson 9y agoThis is what people are missing on Lambda. It's pay-to-play, and for 90% of the sites out there, they're paying too much in comparison. If you're running server instances 24x7 for an application that is doing < 25 requests/minute on average, you would probably find your hosting costs come down (perhaps to zero) and your reliability would increase considerably if you moved to Lambda-style applications. serverless.io is a decent framework to get started (allows for local dev and testing, manages deployment) and is agnostic in terms of deployment target: AWS, IBM, Google coming soon, etc. The only reason we're not rolling it out everywhere at work is because it assumes all developers are deploying directly from their term with god-like CloudFormation access. Nope, nope, nooope. We just need to build the deploy pipeline for it, and then off we go.
- jjeaff 9y agoBut are they really paying too much? I can't think of a lot of products out there, especially those that have a recurring subscription, that don't required some sort of database. So you need a server running a database anyway. It seems that the subscription logic would be a very negligible addition to the instance you have to be running anyway. To me it seems like the only sweet spot for lambda on a large scale would be for those that have consistent usage of a small instance that have some extra functions that need to be highly scalable and are very inconsistent.
- kagx 9y agoFor data storage, you can use aws DynamoDb (NoSQL), which has some generous monthly free tier.
- simonpantzare 9y agoYou could use DynamoDB and S3 for persistence if you're taking the AWS route.
- PaulRobinson 9y agoThere are multiple alternatives to running your own DB service, and again, all pay-per-use. In the original article the author suggested on a successful subscription a write to the MailChimp API (because that's the product). In that example, MailChimp is the DB. You don't have to run a copy of a DB locally if you architect things like that. Obviously if the call fails, you need to think about what you fall back to, which is why error handling is such a critical piece of the the Lambda ecosystem - as it should be for every ecosystem, really.
- lsaferite 9y agoIn this case you should really just dump the subscription on a queue (SQS) and process the payment to mailchimp on a different thread that can deal with errors.
- avip 9y agoIt's serverless.com
- PanMan 9y agoDid you mean serverless.com? serverless.io is a parked domain...
- deleted 9y ago[deleted]
- encoderer 9y agoThis is doubly true with their generous free tier. It applies per-region so for some tasks you can spread workloads out across regions and reduce costs. Cronitor runs about 6 million multi-second lambda invocations a month for $20.
- mherrmann 9y agoIt's unbelievable how easy this is with Stripe in comparison to PayPal. I had to do the latter a week ago and it was horrible [1]. It's no wonder Stripe is so successful. [1]: https://fman.io/blog/paypal-for-saas-99-problems/ https://fman.io/blog/paypal-for-saas-99-problems/
- PetahNZ 9y agoIsn't that why they made Braintree
- venning 9y agoNot sure if you're implying that PayPal "made Braintree" or just that someone made it, but PayPal didn't acquire Braintree until 2013, after being founded in 2007 [1]. [1] https://en.wikipedia.org/wiki/Braintree_(company) https://en.wikipedia.org/wiki/Braintree_(company)
- deleted 9y ago[deleted]
- scandox 9y agoUse Braintree and have to say I like it. Paypal are a tad evil though.
- amelius 9y agoCertainly, it's not rocket science either. I wonder why we don't see much more competition though.
- fenesiistvan 9y agoThe problem is that Stripe is still not usable in the half of the world, including my country, Romania.
- neximo64 9y agoYou can use Atlas cant you?
- fenesiistvan 9y agoIt is a bit overkill to establish a US company just to be able to accept payments. The only real alternative is PayPal at this moment.
- gerenuk 9y agoCheck out fastspring.com
- fenesiistvan 9y agoWe are using share*it: https://www.mycommerce.com/ https://www.mycommerce.com/ Mostly same as your suggestion.
- mrunkel 9y agoWhat is Atlas in this context?
- klausjensen 9y agoStripe's offering to set up a company in the US, with bank accounts and everything. https://stripe.com/atlas https://stripe.com/atlas
- mrunkel 9y agoAhh. thanks. I googled for Atlas, but as you can imagine, lots of things came up..
- l5870uoo9y 9y agoStripe charges 2.9% + $0.30 per transaction, the others mentioned have a monthly fee and then lower transaction fees. So Stripe isn't remarkably cheap.
- jhall1468 9y agoDepends. Developing intregrations has a cost, and until you're processing enough to offset the difference, using something other than Stripe is bad business.
- wonderwonder 9y agoIt is not cheap. It is however, remarkably well designed and easy to integrate with, provides excellent support via their freenode channel and allows for most of the outside of normal range issues to be easily handled on their dashboard. I integrated with it for one of our sites and now have to integrate with cybersource for another and the difference in documentation alone is night and day.
- the-dude 9y agoFor those who are unaware : Stripe charges significantly less for within EU transactions ( like 1.4% or something ).
- Mojah 9y agoI've been using Laravel Spark [1] for recurring payments built on top of Stripe, and at a 100$ one-time fee for Spark and a small server setup (that I needed for the service in the first place) I think it's a cheap option for recurring payments, too. [1] https://spark.laravel.com/ https://spark.laravel.com/
- aantix 9y agoI did something similar with aMember a few years back. Supports many payment processors; a one time fee. API, etc. https://www.amember.com/ https://www.amember.com/
- oliwarner 9y ago~3%, dirt cheap?! Why are so many of you so happy to throw so much cash away to process money? I know Stripe is lovely to integrate but as a business you have to shop around. In the UK (and EU) card processing is much cheaper. Stripe is closer to 2% but if you shop around, you'll find somebody who'll offer you 0.8-0.9%, give you free terminals and no monthly contract fees. Edit for those asking: Worldpay and Handepay are the best rates I've seen recently. Both for online and off. But again, don't just cluster around one company, harass a few yourself. They're willing to compete.
- kagx 9y agoWould you mind sharing those companies? I'm especially curious since Stripe is not supported in my Country.
- gajus 9y agohttps://www.paydoo.com/pricing https://www.paydoo.com/pricing is one example, > starting at 0.59% + £0.20 adapted to industry type and risk level
- oliwarner 9y agoPhwoar! Edit: Weird that they don't appear to service bricks and mortar retail. They can be much more secure (cardholder present, PIN entered, telephone verified) and therefore lower risk.
- therealmarv 9y agoThat's really interesting. Do you have more examples? Thank you for the suggestion. Stripe is only the best known and is well integrated with other systems. When you use something like Paydoo you have to write e.g. your invoice email system yourself (and for stripe there are third party services which can handle that for you). So Stripe has benefits regarding the ecosystem around it. Edit: Seeing there is also a currency conversion fee (is there something similar on stripe?). I mean with currency conversion+paydoo regular rates you get close to Stripe rates!
- cpt_snowcrash 9y agoI never got around getting the true value prop of recurring solutions such as chargebee etc when used on top of stripe. Stripe already provides excellent recurring subscription payments api out of the box, so why use any of these services. Am I missing something ?
- therealmarv 9y agoSometimes they offer this: UI on top of API, generated invoices (PDF/email).
- keerthiko 9y agoWe transitioned from Stripe to Chargebee importing our Stripe stuff. It was a solid 2 man-months of engineering (of our 4-person company) and we questioned the cost through the process, but it has really paid off. Stripe was a great starting point for us to collect direct payments, but as we grew Chargebee has proven very worthwhile. The main value is central customer and subscription database, which muxes multiple payment methods: Credit Card (via Stripe), Amazon payments, and Paypal. This alone has doubled our monthly paying customer growth. Next it allows us to create invoices, subscriptions and customers data to put in the same database for customers from other channels -- mostly this is our iOS users who have to subscribe via iTunes (due to Apple TOS) -- now we can manage their data in the same place. It is also an integrated coupon management system, hosts custom styled payment/subscription management pages (as opposed to just a tiny payment widget like Stripe), supports more flexibility like trial periods, switching between subscription plans, adding credits to a user's account. We've moved all our non-iOS customers to Chargebee for about 6 months now, and really happy with it.
- robinjfisher 9y agoHave you done any formal ROI on the move to Chargebee? I moved from Chargify to Stripe about a year ago (to save on cost) and the biggest challenge was getting customers to re-enter their card details for Stripe. I offered a coupon for 50% off a month's subscription to entice them to do so but still resulted in a couple of months of paying both Chargify and Stripe while I chased the errant customers.
- Denzel 9y agoThis is simple and cool. You'd still need some way to authorize subscribers on your website, no? Therefore, you couldn't create a serverless subscription blog/website... unless I'm missing something.
- robinjfisher 9y agoThe example given in the article is a pay-to-subscribe mailing list run on Mailchimp where you can use an API call to add the paying user to the list.
- ousta 9y agoid rather use XRP
- ctcliff 9y agoI maintain a small open source library for managing payments websites that uses this architecture [1]. My Lambda costs have been about $0.04 per transaction. Also you can provision AWS from the browser using a CloudFormation template and a Launch Stack URL [2].

- ajainy 9y agoThanks for article. Though I known about Lambda for long time, but this is one nice example, how Lambda can be used. Now I am planning to use to develop some zapier like integrations. -=-= Having said that, before you jump into making free payment forms for your static site, keep PCI compliance in mind. (even if stripe is rendering form using js).
- floodfx 9y agoThis is pretty cool but to be pedantic this is actually API Gateway proxying requests to AWS Lambda not just a Lambda function. Zappa and other Serverless Frameworks sort of obfuscate the fact that API Gateway is setup in front of Lambda but that is what is happening here. Again, cool example.
- dheera 9y agoNow if only my property manager could get with the beat and take electronic payments ... I still have to bike over to their office and drop off a physical check every month because they don't take anything else.
- ferentchak 9y agoCan you use bill pay from your bank?
- livingparadox 9y agoSome banks will even send the check on your behalf. I use Simple bank and they can automatically mail out checks on your behalf, if you set it up.
- dheera 9y agoI think so, but it requires me to call them to set up, I hate calling and being put on hold. And also, phone calling usually involves walking out to the street so I can get reception, yell my social security number in front of a bunch of strangers walking by, and somehow verify my account number and various transactions from my account which I can't do without going back inside, logging in from a computer and checking them, and then having the call dropped because I went inside. Or having my phone battery cop out halfway through being put on hold. I hate phone calling. It's easier to bike to my property manager's office 12 times to drop off checks than make a single phone call to my bank to set up something that should be doable from a web page.
- clintonb 9y agoMost banks allow you to setup bill pay online. The bank will mail a check on your schedule. No need for phones.
- dheera 9y agoI wish. Both of my banks bring up messages saying to call customer service when I click on their respective Bill Pay links. So much for "online" banking. We're back in the 80's.
- likelynew 9y agoI can see many cases where there is need for more control. Yes, we can start and end manually, but is it acceptable to be that flaky with payments. I mean, I have managed my personal server in pretty ad-hoc way and more often than I expected there are some problems with something. I don't think I can trust myself with lambda.
- stevekemp 9y agoRemember that if you use stripe subscriptions you absolutely must setup a webhook, or otherwise examine your logs every month. Why? If a customer is subscribed to a "plan", and their payment fails it is retried three days later, then five days later, then eight days later, and if all three payments fail they're quietly unsubscribed without any notification being sent to you! I have a toy project which has paying customers and last month realized I'd had people using my SaaS for over a year without having paid me. A few failures in a row meant they were unsubscribed, and since I didn't read the reports every month I didn't notice. I reworked my payment system now, to subscribe to webhooks and ensure I find out promptly in the future. Not a huge deal at my volume, but a surprise I could have lived without.
- loader 9y agoBoth webhooks and looking at your subscription settings are important. Here's some documentation on how to do both. https://stripe.com/docs/webhooks https://stripe.com/docs/webhooks https://stripe.com/docs/subscriptions/lifecycle https://stripe.com/docs/subscriptions/lifecycle The webhooks are important because stripe doesn't email you about failed payments you need to do that on your own. And the default for a 3 time failed subscription over a 15 day period is to remove the subscription which you can easily change to keeping it but labeling it unpaid among other things.
- olegkikin 9y agoOut of curiosity, did any of these customers return?
- stevekemp 9y agoI had three users who were really affected, and all of them paid up. None of them "left" really, they were receiving a service from me, just not paying for it. The user who had a years free service I wrote down a little - they should have paid around £140, and I suggested we'd be good if they paid £100. Perhaps I went too easy on them, but I was trying to be nice and it wasn't their fault I'd not been paid, not directly. The other couple of users ranged from 2-8 months of non-payment, or so, and I agreed with each that I'd bill them the full amount as a one-off charge.
- bigtunacan 9y agoI've seen several comments on here about how high a percentage is being charged by credit card processors and this is something I've wondered about for a while. There are some sites where I feel like I must be missing something. As an example; https://www.sendmoneytoschool.com https://www.sendmoneytoschool.com. The site is used to pay online with a credit card for your children's school lunch and it typically charges a $1.50 "convenience fee". It is my understanding that they are not charging schools for the use of this service (I may be mistaken); at Stripe or PayPals fee rates this service would be losing money. Every $100 would incur at least a $2.00 fee. Here a low cost processor like Worldpay and Handepay would allow for a profit; albeit a very small one.
