Why a Generic Payment Platform Is Crucial for the Company You Plan to Become

We all know that untimely optimization is the root of all evil. But I’d like to make the argument that when it comes to your corporation or side undertaking, you really should think about incorporating a payment gateway in a generic way to help scale and innovation to aid your increasing enterprise.

When I joined Roblox 5 several years ago, we ended up not the payments system that could electricity an yearly financial system of $1.9 billion in bookings (as of 12/31/2020), applying 11 payment associates with 59 various currencies across 99 supported countries. I’ll notify you how we obtained right here, and how making a generic payment platform upfront enabled us to ramp up as quickly as our business. Payments are frequently forgotten as a source of innovation and affect. But making your payments system the suitable way up front can open up new opportunities, enable for innovation and optimization, and build a competitive benefit for your enterprise.

To start with, what is a “generic payment platform?” I am working with this phrase as a wrapper for any gateway or processor that facilitates the receipt of payments from customers. I’ll be referring to the third parties that do the payment orchestration as payment providers or gateways. A generic payment system opens up centralized logging, fraud, metrics, security, and swapability of payment suppliers. A generic payment platform enables you to AB-check suppliers that may have better credit card completion fees in unique geographies or fraud prices in selected places. It also enables for computerized fallback if a provider goes down, which occurs far more than any of us would like.

You are bound to alter payment providers, especially credit rating card vendors, down the highway. If you believe your enterprise will be prosperous, the charges you are going to get as a 5-person garage shop vs. a world ecommerce platform are commonly distinct. Also, the service provider you chose early on may well not in good shape your demands as you develop — some of the most common suppliers have constrained intercontinental penetration. There are a lot of factors to switch suppliers and tying oneself to just one might signify you are hurting your bottom line with each purchase.

Roblox makes use of a wide vary of payment providers, and has also discontinued doing the job with just as a lot of. We at present have desktop suppliers, prepaid card companies, and application retail store companies. We have parted methods with at minimum 4 payment companies since I’ve joined Roblox.


I am heading to attract a higher-level architecture of what I imply by plug and participate in payment vendors. Roblox is on a microservice architecture, but if you’re just commencing out, you likely should not be. The logic beneath can be both a company or just separated at the software layer.

Recognize how payment processing is just one particular stage in the all round flow of the payment. Setting up out with one particular supplier is the suitable connect with, but be guaranteed to assume about what would occur if you resolved to include a 2nd. Would it be quick to update the routing logic or would it be another project with a whole lot of refactors? The encapsulation early on will also assist with pondering about safety and PCI Compliance.


I won’t go into a lot of specifics of how we lay out our data, because it may possibly not fit your use case, but at a substantial stage, I want to emphasize that the payment processing step need to be a phase that can easily be replaced and transformed. Do not tie your knowledge suppliers to the payment processor’s info layouts. I would even advise seeking at unique providers and how they take care of the concepts of auth, seize, and subscriptions, and come to a decision on a generic info keep with all payment supplier-specific logic encapsulated in a fully independent desk.

Data will most probably be most tricky for you to update afterwards. Imagine about what you are going to need to have from persistent vs. not-persistent details, and how very long you will will need this data saved. I would strongly suggest structuring the details to make it possible for for later on integrations with a subscription solution. Even however you may possibly not be pondering about subscriptions now, if your small business even has a likelihood to transfer down that road, system the information shops to accomodate for that. I will not go into all the rewards of a membership-based monetization strategy (there are a ton of sources online for that), but predictable income lets for you to program further more in advance for your enterprise.


Subscriptions are another place that will gain from generalizing away from payment service provider-precise logic. The subscription architecture for payment vendors is vastly distinct. Most 1-time payment buys adhere to the identical product of “charge the consumer now.” For subscriptions, however, a couple diverse types exist:

Make absolutely sure that all your subscriptions appear by way of just one central information pipeline with generic renewals, cancellations, and (most importantly) grace intervals. Some modals like the pull modal will permit a membership to continue to be energetic unless of course you hear back again from the company. If your services goes down or has ongoing timeouts you will be caught furnishing a product or service without having basically charging the user. This may be alright relying on what membership featuring you have, but our virtual currency has an intrinsic worth so we need to have to be excess watchful on membership renewals and cancellations.


I hope I was able to encourage you of heading the generic route from your early implementation of your payment gateways. I won’t suggest what payment service provider you must implement, but with any luck , you see that your choice of payment company isn’t the most significant selection. The most important selection is how to architect your process in the ideal way to have the choice to effortlessly change your payment service provider in the future.
