Ask HN: What do you use for recurring billing?

65 pointstamalsaha00128 comments

I am looking for a simple solution for recurring billing. My requirements are:

- Per user per month. New users can be added or removed any time. Support for initial 14 day trial.

- Per user billing for annual subscription. New users can be added during the year.

I am looking for something that supports True Up accounting model. I have looked into Braintree and Stripe api. None of them seem to support anything beyond simple recurring billing.

What have you used for this type of common billing patterns in SAAS apps?

Roll your own. Start with a subscription table with a paid_through column, and a payment table for recordkeeping. Your billing code is a daily cron job running a single simple script, that selects all rows with paid_through less than current date, charges each user's card on file, and updates the two tables. Discounts, different subscription terms, receipts, dunning mails are all simple additions to the daily billing script that you can add as you grow.

This has worked for me with tens of thousands of customers and millions in billings, and I've never had to worry about being locked into some payment company's proprietary system. Whatever pricing scheme you initially come up with for your app probably won't be right. You might have 6 plans when you only need 2. You might find out you were charging a flat monthly rate when you really need to be charging per widget or per user or per server. The more you rely on someone else running your billing, the harder it will be to experiment and find the right way to do billing for your customers.

You can avoid being locked in to a payment processor for storing and charging payment info too. I use Spreedly (https://www.spreedly.com) which provides payment card tokenization and a single unified API for over 100 payment gateways. I can use Braintree today, Stripe tomorrow and ShinyPaymentStartup next year without changing any code or re-collecting billing info from customers.

This. Make it easy for yourself to avoid lock in. The code in question is not that complex either (100-200 lines)

+1 The few days you spend on this will save you many thousands of dollars in fees in the years to come. Great ROI. Having said that, I found Authorize.net to be a good way to go. No affiliation, just a happy customer.

> I found Authorize.net to be a good way to go

Authorize.net is just a payment gateway, an API between you and a merchant account provider. Since just about every API has existing client libraries you can use, they're no better or worse than each other.

What makes Authorize.net a bad choice is that you don't own any of the data you store with them. If you keep your customers' billing info in their CIM vault, it's never coming out. They won't give it to you, and they won't transfer it to another account.

That means if you ever want to change merchant account providers, or your account gets frozen, you're stuck. You need to re-collect every customer's billing info to continue their subscriptions on another platform, and that usually means a big chunk of your customer base will churn out all at once.

This is what using an independent payment vault solves.

That's true. One thing I like about CIM is it's trivially easy for me to be PCI compliant, because that particular sensitive data doesn't hit my server. But you're right - I can't export it.

Have they come out with a new integration method? Last time I looked at Authorize.net, all the sensitive data hit your server before you stored it in CIM via an API. You'd need quarterly vulnerability scans, SAQ-C or worse, all that onerous stuff.

I don't remember what they call it, but basically you pop-up a form that is loaded from their website that gets credit card info, etc, and then posts back to their site. So a credit card number never touches my server. It's very nice.

We actually built a similar version based using Braintree api. But somehow from all the hype of Stripe/Braintree, I thought it will be one click and go. But this requires continued time investment everytime I want to change something. Also, I am little worried that we will mess up money stuff. I just wanted to see what other people are doing. Looks like we should stick to our home grown solution.

This means you actually store customer credit card numbers and have to deal with PCI compliance? Is ensuring PCI compliance very onerous?

Nope, I don't store credit card numbers, payment info never touches my servers at all. I mentioned that I use Spreedly. Spreedly works exactly like Stripe Checkout if you've ever used that. You only store a token referring to payment info they're storing, and pass that token to the API to make charges against it as needed.

That's at least $200 to use Spreedly. What benefit have you gotten with it so far? Do you find yourself switching gateways to get lower rates, or do you just stick with one gateway?

Actually $150/mo for up to 5000 stored cards. The benefit is mostly peace of mind: a "PayPal horror story" type situation (frozen account), processor raising rates, or payment gateway having an extended downtime event are non-issues instead of major headaches or potential company-enders.

Is there reason example of a gateway that was down more than a day or 7? A big player like stripe just vanishing in the night?

Would rather spend $150 on some AdWords or something that has a more realistic chance to do something.

Can't stress enough how much I agree with this. I've seen far too many businesses off-loading all billing jobs to an external provider (Stripe, Braintree,...) and then facing troubles when subscriptions get a bit more diverse and greater flexibility and control is needed.

I've written about this in one of my posts (http://codeandtechno.com/posts/subscription-payments-use-ext...). Basically, let an external service handle the PCI compliance part (storing sensitive data) and just use their tokens in your billing implementation.

Just recently followed Dan's advice from an early comment of his [1]. Turned out being easier than other solutions to implement anyway. It's doing exactly what I need now, and not more. And it forces you to be very aware of this workflow. I hope I have the need to add the "simple additions" later.

I had to build a custom billing system for Cachoid too ( https://www.cachoid.com/ ). You definitely need the upfront time to build it from the ground up but it's worth it in the long run. I'm doing monthly recurring with Stripe and one-time also with Stripe and Paypal. And Bitcoin through Stripe.

I found that charging per server/FQDN (one FQDN === one service === one billing item) rather than per user provides more flexibility. But I'm not comfortable with single-homed APIs like Spreedly. What if it gets acquired tomorrow? It isn't something you can replace overnight.

I'd rather have a multi-homed setup with direct relationship with multiple gateways

Not thrilled with it but we use paypal for our reoccurring payments. Users trust it and don't have to fork over their credit cards, but I get scared every time someone lies and says they didn't authorize the charge and having to prove to paypal that they indeed did get what they ordered fearing they'll freeze our account or something. Also it does cause confusion where the subscription is managed at paypal instead of on our site. That said, it does work 99% of the time.

Chargebee works on top of payment gateways like Stripe or Braintree. They give you more flexibility around subscriptions than those payment gateways support out of the box. Plus they don't charge you a fee (excluding payment gateway standard fees) until you make your first $50k in revenue with them.

Your other best bet is Recurly. They have lots of options for subscriptions but it may not make sense if you don't have any revenue yet.

Yup, we've been using chargebee for about 4 years, can confirm they're great.

I've looked at all the providers and couldn't find one that was flexible enough and also isnt overcharging, I.e. paying for the service, credit card charges, payment gateway, etc.

That said, I've found cheddargetter to work quite nice. Has an API, includes the payment gateway, and provides enough flexibility for custom prices per subscription. So far I've implemented three startups with it.

Hope this helps.

Yes, I've also had a good experience with Paddle. It is easy to setup and also handles VAT/taxes.

use a provider if you can integrate in a day or two, then later think of rolling your own if you anticipate any issues. you could find a provider that might be interested in writing certain features for you or has a decent enough api for you to extend.
