Payment gateways development

Services for developing e-commerce payment gateway

Let’s say you launched your own ecommerce business – online store. You developed an attractive, user-friendly design, filled it with product cards, and integrated it with a CRM system. The point is small – to install a payment gateway to maintain merchant account. But is it “small”?

Developing a payment gateway for e-commerce

A payment gateway is a service that will allow you to accept payments from customers. It authorizes visitors and processes transactions on their cards (both debit and credit). The gateway must ensure the smooth passage of all transactions so that, as a result, funds for the goods purchased on your site are credited to your account. It is easy to understand that inside the gateway, the user’s confidential data must be encrypted in order to transfer it in the required format from your portal to the payment processor (to the bank).

The gateway not only provides the possibility of making a payment – its task is to facilitate the “financial connection” between your website, the buyer’s bank (from which the transfer will be made using his card) and your own credit institution, where this money will be credited. Of course, safety is paramount here. And it provides an encryption module, which not only needs to have the necessary certification, but it also needs to be correctly installed and configured. You need in services for developing e-commerce payment gateway.

OnePix specialists have all the necessary competencies to compile and configure the processing software node (this is another name for the payment gateway). However, it seems reasonable to consider this system in more detail, focusing on its main characteristics. This is necessary so that you can correctly assess your own strengths when deciding how to create a gateway.

What to look for when choosing ecommerce payment gateway?

The system that processes payments on your site should be consistent with the business model you have formed. The point is that the final amount payable can be composite and depend on many parameters. The processing platform should be able to correctly and visually calculate it.

What you need to pay attention to when choosing services for developing e-commerce payment gateway:

  1. System scalability. It must have the ability to increase productivity. At the start of your project, perhaps 1 transaction per minute will be enough (also not bad). But if your business grows, it is quite possible that the number of transactions will exceed 20 units per second. And the processing system is obliged to cope with this flow of transfers without interruption. Replacing a payment gateway is always a very big problem for the owner of an online store, since his resource will be forced to be disabled for some time.
  2. Functional extensibility. This means the ability to add new features to the processing system that increase its performance. In particular, we can talk about the processing of additional payment methods, the addition of certain forms of reporting, online payments, domestic transaction, international transactions, alternative payment methods, other service modules and payment options. It is very important to foresee this at a very early stage so as not to subsequently switch to another payment gateway. OnePix software developers place particular emphasis on the potential associated with functionality. Let payment gateways work not too fast, but it must have the ability to upgrade.
  3. Continuity of work. Unfortunately, it is impossible to ensure the complete absence of any failures in the payment gateway system in ecommerce industry. However, it is not possible to do without technical payment gateway support at all. In general, the processing service should work 99.99% of the time, which means that technical customer support (services online) should function 24 hours, 7 days a week. At the same time, of course, DevOps engineers must be present in the state, who have the technical capabilities to ensure its sustainability.

Challenges faced by the developer

If your project initially does not provide for a high volume of payments, then it will require a minimum of options, which means that there will be no problems with setting up. However, if the business scales up in the future, the number of transactions will multiply, every time you have to add new payment method, on and on, as online payment function from other countries and alternative payment options will need to be accepted. In a place with this, the number of nuances and difficult moments that will need to be addressed will increase. Let’s analyze them sequentially.

Connecting to the API

To the great regret of the developers it is impossible to connect to the API of the processing service by making some minor change to program code of any payment gateway option. Here it is required to take into account the peculiarities of payment process and information exchange: whether the receipt of money is confirmed or not, whether there was a disconnect or everything went smoothly. Absolutely all the nuances will have to be taken into account, because the customers need the stable operation of the gateway under any external circumstances.

Connecting a processing service is objectively difficult. And even a team of experienced developers (such as OnePix specialists) can take up to 3 weeks to complete this. That’s why our programmers pay special attention to this, so that the connection is made without problems.

Design an online payment system

Commissions for different banks and payment systems vary. Of course, the customer is interested in processing fees at the lowest rates, but in order to ensure this, one has to resort to artificial routing. However, one payment gateway provider interacts better with domestic transactions, another processing service is specializing on international payments – their currency conversion fee is the lowest one. And the most popular payment gateway providers generally guarantee better commissions when interacting with any payment network (international fees per transaction here are the least ones). Therefore, several processing services must be connected to the gateway at once. Organizing multiple gateways on the site at once is an extremely difficult event, after all, because of setup expenses at least.

OnePix specialists use an additional software “layer” in order to determine the source of the payment. So you can choose the best rate of processing fees. At the same time, it should be taken into account that the chosen route may not always be beneficial for the processing company, which is interested in ecommerce sites paying the highest possible gateway fees. In order not to encounter a direct ban, the software module must be able to initially determine the route of the funds in order to guarantee the highest speed and reliability of the transaction.

Router development is universal, reliable “payment solution”. It’s not that important for a mobile ecommerce with a small payment flow. However, if this is a development store on marketplace then it is strongly recommended to foresee it initially, since it will be much more difficult and expensive to integrate it later. Best payment gateways includes such modules from the very beginning.

Designing electronic payment system

The buyer just fills in the fields with his card data and clicks “Pay”, but a lot of online transactions take place inside the payment gateway. All of them must flow clearly, consistently and without delay. Only in this case it will be possible to say that the payment gateway works without failures.

Here is a rough list of these “events”:

  • the processing company requests the buyer’s bank and receives transaction data from it;
  • the bank contacts the hosted payment service of the point of sale;
  • the state of payer merchant accounts, the processing center and the bank serving the online store is updated with the corresponding SMS sent to user accounts. After that checkout process starts.

For the client all these Shopify payments of order management should take less than a second – pressing a button, paying, checking an updated invoice. OnePix specialists pay a lot of attention to the resource intensity of the payment gateway being designed, since the speed of its operation directly depends on this.

The best payment gateway integration process

You need to understand that the most payment gateways options are the separate software modules (like a plug-in) that is built into the architecture of the developed ecommerce site and increases its functionality (now it becomes possible to make online purchases on the resource, and not just look at the product). However, it should be noted that this special “software application” is not cheap, which means that there will be a lot of people who want to optimize their costs, especially in a small businesses environment. We will tell you what options exist for this and try to choose the most reasonable way to acquire a payment gateway. It should be noted right away that all the methods discussed below have been encountered by OnePix programmers more than once, so the conclusion is so categorical.

Modul producing at payment gateway software development company

The more in demand a computer program (or a separate module), the more expensive it is. This is probably the most expensive way to get services for developing e-commerce payment gateway. This is a law to remember, when applying for some kind of software product to the open market. And do not think that professional developers will “pity” you and give you a discount.

Here it is worth proceeding from a different point: as a rule, if you already have some kind of commercial Internet resource, then you also have a development team that created it. Imagine that you will create a processing system on your own – and so third-party professionals will charge you much more than you can spend in the process of your own development. After all, one should not forget about the high rate of return adopted in the IT industry.

Rent a payment gateway for ecommerce website

Renting a processing system is a very non-trivial move. In short, it is fast, efficient, and at first glance, not very expensive. However, any lease is a rent, that is, an expense item that will not be connected in any way with your revenue or the accumulated total margin. Sales may not go as intensively as indicated in your forecasts, that is, instead of 2-3 per minute there will be 1 in 5 minutes, but you will have to pay for the rental of the gateway at the full rental rate. You should not out of the blue add risk to your business project by increasing the items of protected expenses. OnePix financial managers categorically advise against doing this.

Payment gateway purchase

Buying is always good: you get a finished product, you don’t have to pay anything after that, you have a working software module. The only bad thing is that the cost of the processing system can be a sum with a large number of zeros. In addition, you should not discount the configuration, debugging, and setup fees in order for the processing module to meet all your requirements.

Development by hired specialists from OnePix

Many get lost looking at the deadline for launching an online store, for example, and evaluating current results. Independent development in this case seems to be something that cannot be handled under any circumstances. And this is the main mistake.

Simply hire a team of highly qualified, competent developers from OnePix, and you will receive required services for developing e-commerce payment gateway. The result will be ready in time and at a very reasonable price. Conclude smart contracts with selected specialists and specify in them the obligations of the parties, guarantees, all your requirements (for example, the mandatory annual PCI DSS certification of the processing system), as well as the terms of remuneration – in a mandatory connection to the finished result.

As our rich practice shows, this is the most effective way to create and run any software package. And this is reasonable: if you want something to work, entrust the creation of it to professionals! We are looking forward to establishing long-term cooperation with you.

How we work

We break down the work into stages
Task
Prototype
Design
Frontend
Backend
Release
Support
Task
Technical specification is a document that describes the goals, requirements, and functionality of a web project under development, and also defines clear timeline for its implementation. The technical specification is essential for the success of any project as it ensures that the client receives exactly the product agreed upon.The technical specification is the basis for communication between the client and the developer and serves as a guide for all stages of development.The clear project structure provided in the document protects the client from additional unplanned expenses that may arise without it.
Task
Prototype
Wireframing process is creating visual flowcharts that define the interface architecture and arrangement of all elements on the pages of the website or mobile application. Such prototypes demonstrate and determine where exactly and in what proportions functional blocks will be implemented. A prototype forms the basis, and then designers create a visualization of the project. Recommendation materials and references agreed upon with the client and reflected in the technical specifications can also help the designers. Generally, the materials relate to colors, shapes, and logos that should organically appear on the new site.
Prototype
Design
The modern approach assumes the presence of block elements for arranging content on pages. Under this approach, any new page can be assembled of existing elements in an original or standardized layout. It makes further content management easier even in cases when a client decides to do it on their own. When the layouts and elements are ready, they are sent to the client for approval.
Design
Frontend
Then design layouts are sent to the front-end developer, whose task is to turn the template into code and connect the layout with the control system. First, a home/landing page is created. Then, all subpages are added following the site hierarchy. Dynamic elements and adaptability for mobile devices are implemented after the static layout is ready. Then, layout files go through testing by an expert who scans for bugs on the user side using various devices and browsers, checks the code validity, and whether the final layout corresponds to the initial one. The results of this stage are provided to the client.
Frontend
Backend
In our company, QA (quality assurance) occupies a special place. We not only do testing as such, but we also ensure the quality of the final product. The process starts with the communication with our clients who inform us about their general needs and the ultimate goal. At this point, we figure out how to make sure that the final product will be spotless. Further, (at the stages of design creation, development, implementation) we responsibly keep on pursuing our goal - creation of an excellent product. This implies design development that fully satisfies our customers & the application of the latest technologies & writing autotests for catching bugs at the earliest stage & compiling a complete project documentation (test plan, checklists, test cases, etc.)
Testing
Release
This stage comes before delivery to the client and includes final testing of the project, code review, code optimisation, and project launch. It is important to test all the aspects so that a user doesn’t face any errors in the release version and a client doesn’t miss the commercial benefit. Each software module and all the visual elements are thoroughly checked for errors and breakdowns. We use code validators and cross-code reviews to ensure that the project complies with current web standards and meets all the requirements of the technical specification. Valid code is required for cross-browser and cross-platform compatibility, as well as for SEO. After the site has been thoroughly checked, the next step is uploading the project to the server. After successful uploading, the project is checked again to ensure its integrity and exclude possible errors.
Release
Support
Maintenance after project delivery includes monitoring, improvements, and regular updates. It is important to remember that a website is more of a service than a product. Submitting and uploading the site to the client’s server is not enough. It is necessary to monitor the website under load within 1-3 months to ensure that it works correctly for mass use. That will adjust its performance if the client’s business has a seasonality factor. For example, a feedback system added to the website will enable the detection of possible problems that only end users face. In this case the highest priority is to fix the problems as quickly as possible - If you don't, one day you may find your clients prefer using a different site.
