Ask HN: How do you build a payments app like Venmo?
I understand the MSB MTL side of the business and the regulatory barriers of entry, but how difficult is it to create a payments application that allows businesses to perform Bank Transfers and Credit/Debit transfers between two parties?
- idax 8y agoAny payments developers out there? What does it take to connect to different banking systems to transfer funds and how do you go about it?
- masudrhossain 8y agoBuilding from scratch or using an API? You can use plaid.com for that. It also integrates with stripe.com pretty well too.
- idax 8y agoIdeally building from scratch because the platform relys on taking a small percentage of each transaction for revenue.
- idax 8y agoPlaid seems like an incredible company, going this route would save a huge amount of engineering initially, but would cut into revenues. I might explore this further. Thanks!
- pepper_sauce 8y agoIf you're in the EU, read up on PSD2. It's opening up payments significantly.
- idax 8y agoUS Based, but I read an article about it. Pretty interesting.
- wilde 8y agoHow much are you willing to spend per transaction? With Stripe or Braintree it’s trivial but expensive. Are you targeting just the US market and dollars? Going directly with a bank is cheaper but more complex [1]. And unless you’re adding significant value you’ll probably need a money transmitter license in your state. And if you’re planning on letting any asshole on the internet use this, you need an anti-fraud strategy because settlement times are measured in days and there are plenty of ways that money can be sent but never refunded. Good luck! [1] http://engineering.gusto.com/how-ach-works-a-developer-perspective-part-1/ http://engineering.gusto.com/how-ach-works-a-developer-persp...
- idax 8y agoThanks for this. That link is extremely helpful and goes in depth to the ACH Networks from a developers perspective. Cheers!
