Don't make mistakes payment processing company How to choose a company! Important points in organizing in-house requirements and screening and operation

When launching an e-commerce site or online sales, choosing a payment processing company company is crucial.
The reason is that the service you choose will change the payment method you can deploy, the ease of operation, and even the scalability in the future.

However, there are many cases where they do not know "which company to choose" or "what criteria to compare", and make decisions based only on fees and rankings.
Choosing the wrong payment can lead to fatal problems for your business, such as delays in reviewing the start of the payment, fraud damage, and increased operational load.

In this article, we will organize the structure of payment processing company company and explain in detail everything from understanding the current situation of the company to selection criteria and points to check before implementation.
Gain the foundational knowledge to determine the right payment configuration for your company.

payment processing company Why is it difficult to choose a company?

payment processing company It is easy to stumble when choosing a company for the following reasons:

1. payment processing company It is difficult to understand the differences between companies
2. There is a lot of comparative information and no judgment criteria
3. payment No experience in implementation, making it difficult to make decisions within the company

First of all, if you organize "why it is difficult to decide", it will be easier to see the comparison axis necessary for your company.

payment processing company It is difficult to understand the differences between companies

payment processing company One of the reasons why it is difficult to choose a company is that it is difficult to see the differences between each company.

All companies have many explanations such as "responding to diverse payment method", "supporting implementation", and "improving operational efficiency", and it can be said that it is difficult to grasp the difference just on the surface. Therefore, even if it looks like a similar service, there are differences in the way the review is payment method conducted, the payment cycle, and the scope of support, which can actually be handled.

If you compare the name and impression alone, you may choose a service that does not suit your company. First of all, it is essential to look at what is the same and what is different.

There is a lot of comparative information and no judgment criteria

payment processing company It is easy to get confused when comparing companies because, while there is a lot of reference information, it is difficult to determine the judgment criteria that suit your company.

When you search, you will find many ranking articles and comparison sites, but the items that are emphasized are different for each article. Some are centered on fees, while others prioritize visibility and introduction Actual, making it difficult to see the conditions required for your company just by reading it as it is.

The more information you have, the easier it seems to choose, but if you compare without an axis, your judgment will be more likely to waver. It is important to determine your company's priorities first.

payment No experience in implementation, making it difficult to make decisions within the company

payment If you have little experience in implementation, it is difficult to make decisions within the company. Since payment is directly related to sales, it is difficult for the person in charge to make decisions alone, and opinions from sales, accounting, system departments, etc. are also involved.

However, the emphasis on each department is different. Sales is about sales opportunities, accounting is about payment management, and the system is concerned about the load of coordination, so it is difficult to get the story together. In addition, when you are implementing it for the first time, you may not know what to check and stop in front of comparison.

Therefore, it is necessary to proceed from a perspective while organizing the judgment materials.

payment processing company Company Structure and Roles

payment processing company In order to choose the right company, it is important to first understand what kind of role the service has. If you compare without knowing how it works, it will be easier to focus only on fees and features.

Here, we will sort out the basic roles of payment processing company companies and explain why they are important for businesses.

payment processing company What is a company that manages payment processing in bulk?

A payment processing company company is a company that intervenes between e-commerce site and online service providers, credit card companies, and various payment processing business parties to help multiple payment method contract, connect, and process sales. A payment processing company company is a service that allows you to manage multiple payment method processes together.

When selling products and services on an e-commerce site, each user has a different payment method they want, such as credit cards, QR code payment, and buy now pay later. It can be cumbersome for businesses to contract these payment separately and manage them separately.

Therefore, it is the payment processing company company that intervenes and organizes the procedures. Since the point of contact can be unified, it is easier to reduce the burden of introduction and operation. The more companies that want to handle multiple payment together, the more likely it is to feel the need.

merchant screening to payment management

payment processing company The company not only provides payment method, but also assists with pre- and post-implementation operations.

For example, you need merchant screening to use Credit card payment, and they may be able to coordinate the application and confirmation process. In addition, one of its roles is to be able to organize sales data, manage payments, and even prepare refund processing mechanisms. Since the number of items managed individually by the business is reduced, it is easier to reduce the burden of accounting and operation.

Since payment is a business that is directly related to sales, it is important to see it as a supporter, including daily management, rather than just providing payment method.

Playing a role in intervening with credit card companies and payment processing business

payment processing company The company is responsible for entering between the e-commerce site, the credit card company, and each payment processing business party, and is responsible for coordinating contract, connection, and sales processing. When businesses interact with each company individually, the burden of contract procedures and management is likely to increase.

In that respect, if you use a payment processing company company, it will be easier to unify the contact point and reduce the time and effort when introducing it. It's also important for the efficient operation of multiple payment method.

How to choose a company that is prone to failure payment processing company

payment processing company If the company chooses the wrong perspective, the burden will likely increase after implementation. In particular, if you make a decision based only on superficial comparisons, there will be situations where you feel that it is "different from what you expected" after the start of operation.

Here we will sort out common selection mistakes.

You choose a payment processing company company based on commissions alone

If you choose a payment processing company company for fees alone, you may add another burden after implementation.

payment Fees are the first item to focus on because they are directly related to costs.

However, in actual operation, initial costs, monthly costs, payment cycles, refund support, and support coverage are also factors that have a significant impact on the business.

For example, even if the fee seems low, a longer period of time to deposit can affect your cash flow.

Additionally, limited support may result in increased internal verification work. It's important to look at and judge not only the cost, but also the entire operation.

Judge by ranking and popularity

Choosing based solely on ranking and popularity tends to lead to failure.

The reason is that a company that you have heard of a top service or name may not necessarily be a good fit for you. Ranking articles have different publication criteria for each article, and it can be difficult to understand what is important.

Also, even if you are a well-known company, if it does not match the payment method and business flow you need, you will find it difficult to use it after implementation. Comparison articles are helpful, but you don't want to end your judgment with just that.

It is essential to check the perspective in light of the company's conditions.

Compare your company's requirements without organizing them

If you start comparing without organizing your company's requirements, it is easy to shake the axis of judgment.

payment processing company Each company has different sales forms and scope of service. Therefore, even if you do not organize your company's products, billing methods, necessary payment method, and internal operation system, you will not be able to see whether it is suitable for your company.

The more comparison items you have, the more likely you are to choose, but if the premise remains ambiguous, it is easy to mismatch the situation after introduction, such as "I can't use it as expected". First of all, it is necessary to verbalize the current situation of the company and then proceed to comparison.

Understand the current situation of your company that needs to be sorted out before selection

Now, let's sort out the basic conditions of your company that you want to check before comparing payment processing company companies.

If you organize your sales methods, sales forecasts, and operational structure in advance, it will be easier to determine which functions you need and which are not.

Here, let's take a look at the basic items you should check before making a choice.

Organize sales formats (product sales, digital content, each time, recurring payment)

The first thing you want to check is how your company will sell your products and services. Whether it's merchandise or digital content, pay-as-you-go or recurring payment, the payment features you need will change.

For example, if your focus is on one-time purchases, basic payment functionality may be sufficient.

On the other hand, if you plan for a monthly or subscription plan, you also need to be able to respond to recurring payment and manage billing errors. If you choose these sales forms without organizing them, you may find a lack of functionality after implementation.

First, let's clarify how we sell our company.

Assume expected sales scale and business growth

The next thing you want to look at is the scale of sales at the start of the business and how much growth you expect to grow in the future.

If you choose a payment processing company company based only on your current size, it may be difficult to operate when the number of transactions increases. Even if the number of orders is small immediately after launch, it is not uncommon for the number of orders to increase due to the expansion of sales channels and advertising measures.

At that time, the ability to respond to the number of transactions, payment conditions, and ease of adding functions will affect it. Even if it seems to be fine at the moment, if it does not suit future growth, it will need to be reviewed. It's important to think not only about the present, but also about the business scale a little ahead.

Review fraud risk and operational posture

Before implementing payment, you should also review the risks of fraud and the internal structure that can handle them.

While payment can lead to sales, it can also lead to fraudulent orders and chargeback actions. For example, if you are dealing with high-value products or digital products, you may be able to offer products before you even notice the damage. Therefore, it is important to think about how much you will focus on fraud countermeasures.

You also need to organize who will be in charge of refund correspondence and order confirmation, and how much operational work can be done within the company. Depending on the operational structure, it may be better to choose a payment processing company company with enhanced fraud detection capabilities and support systems.

Identify the payment method you need

payment processing company Before choosing a company, it's important to first organize the payment method you need for your company. This is because if the user doesn't have the payment method they want to use, it will lead to abandonment in the middle of the purchase.

GMO Payment Gateway's "payment method Usage Intention Survey 2025" shows that credit cards and PayPay tend to be used more in both product and service e-commerce.

In addition, the usage rate of PayPay is 30.4% for product sales e-commerce and 41.2% for service e-commerce, indicating that the payment method that is easy to choose varies depending on the product.

In order to determine which payment fits your customer base, it is important to consider the payment structure based on these survey results.

How to choose the right payment processing company company for your company

payment processing company When choosing a company, it's important to look not only at the price but also on the criteria if it fits your business. First, use the following checklist to visualize the conditions you need for your company.

Check which payment method are supported

The first thing you want to make sure is that your customers support the payment method they want to use. payment Limited methods can easily lead to abandonment mid-purchase.

For example, some people use credit cards, while others prefer QR code payment or buy now pay later, such as PayPay. Which payment method you need depends on the products you sell and the customer base.

Therefore, don't just look at the number of responses, but also make sure you have the right payment for your users. If you look at the presence or absence of recurring payment, it will be easier to prevent mismatches after implementation.

Check system linkage (EC cart and accounting)

payment processing company When choosing a company, you should also check whether it is easy to link with the e-commerce cart and accounting software you are currently using. payment Even if the functions are in place, if you have to manually perform order management and accounting processing, the daily operational burden will be heavy.

For example, if you manually enter sales data every time, it is easy to miss confirmation or make input errors. On the other hand, if the system is linked, it will be easier to manage order information and sales information together.

Before implementation, it is important to check how much efficiency can be achieved while comparing it with the current business flow.

Check scalability (overseas support, payment addition)

payment processing company The company should not only see if it fits the business today, but also if it can accommodate future changes. Even if it looks good enough at launch, the functionality you need may change as your sales channels expand and the number of deals increases.

If you want to start selling overseas in the future, you may need to support multi-currency or overseas issued cards. You may also want to start with a credit card and want to add QR code payment or buy now pay later later.

If you choose a service that can flexibly respond to these changes, it will be easier to reduce the hassle of switching later.

fraud Review measures and security measures

payment processing company When choosing a company, you should check the fraud measures and security measures. Because while payment generates sales, there is also a risk of fraudulent orders and information leakage.

Especially when dealing with high-value products or digital products, the impact of damage cannot be overlooked. Therefore, it is important to look at what measures are in place before implementation.

When checking, it will be easier to make a decision by looking at the following items.

• Does it support identity authentication?

• Is there a fraud detection mechanism?

• Do you have a system in place to monitor suspicious transactions?

• Are there standards for information management?

• What kind of confirmation work is required on the company's side?

If you understand these points in advance, it will be easier to anticipate operation after implementation. In order to continue selling with peace of mind, security is an item that should be checked as soon as possible.

Review merchant screening content and deployment timeline

Before introducing the service, you should also check how the review will proceed and the schedule until the service starts.

payment may not be available immediately after application, and it may take some time to verify the merchant screening and required documents. If you have a set start date, prolonged review may affect the launch date and campaign launch.

In addition, depending on the products handled and sales methods, there may be more items to check. Therefore, it is essential to understand how long the review will take and what to prepare in advance.

In order to ensure a smooth implementation, you should compare not only the price but also the realistic flow to start.

Check your inquiry response and support coverage

You should also check the ease of handling inquiries and the scope of support before contract. This is because payment is not the end of the introduction, but after the operation begins, you will find things you want to check.

refund There are situations where it is difficult for the person in charge to make decisions on how to proceed with processing, how to view payment confirmation, and how to respond to payment errors. Therefore, it is important to see in advance how much support you can get when you are in trouble.

When checking, it is easier to compare by looking at the following items.

• Is the contact point easy to understand?

• Can we consult both before and after the introduction?

• refund Is there a notice on cancellation or cancellation?

• Is the scope of response clear in the event of a failure or error?

• Is the means of communication such as phone and email suitable for your company?

• Japanese languages are available for support (for global payment processing company companies)?

In order to reduce the burden on the company, look at the support system along with the functions and fees.

Check your payout cycle

payment processing company You should also check the company's payout cycle beforehand. Because even if sales occur, they are not always credited immediately.

For example, if you have a long time to payout, you may incur payment of your ad spend and purchases first, which can affect your cash flow. Immediately after launch, there are cases where there is no cash on hand, so the timing of the deposit cannot be overlooked. If you know when sales money will come in, it will be easier to plan your finances in advance.

refund ・Cancellation ・ chargeback Check how to respond

Once operational, you may need to respond to refund, cancellations, and chargeback. This is because depending on the content of the product or service, there may be cancellations and payment problems after ordering.

In addition to customer refund requests, you may also be required to take chargeback action on transactions that suspect fraud. If you proceed with such a response without knowing the procedure, it is easy to miss confirmation.

It is important to understand the flow in advance and decide who will respond to it in order to stabilize the operation.

Check accounting processing and operational load

When you implement payment, you will not only check sales, but also take care of accounting and day-to-day administrative tasks. The more payment you have, the easier it is to do more detailed tasks, such as confirming payments, reconciling sales, and verifying refund processing.

When it comes to checking whether the transaction data and accounting processes match, the more manual work there is, the greater the burden. Also, if the number of people in charge is limited, other tasks may be wrinkled.

There are loads that are difficult to see before introduction, so it is necessary to assume the time and effort required for operation.

payment processing company Points to check in advance when selecting a company

Next, compile a checklist of items you want to check to reduce mismatches after implementation.

When checking, it will be easier to organize by looking at the following three points.

• contract Conditions

• Implementation Schedule and Review Period

• Support after the start of operation

contract Conditions

When looking at the quote, make sure to check not only the payment fees, but also the entire contract terms.

Even if the amount seems low, the actual burden will vary depending on the initial cost, monthly cost, and cancellation conditions.
In addition, if you do not look at the refund costs and payment conditions, you may incur unexpected costs after the start of operation.

contract If you organize the conditions beforehand, it will be easier to prevent deviations after implementation.

Implementation Schedule and Review Period

contract Before you do it, check the number of days until the introduction and the review period.

payment may not be available immediately after application, and it often takes time to prepare and merchant screening the necessary documents.
If you have a set start date or campaign time, the delay in review will affect your business plan as it is.

If you know what to prepare at what stage, it will be easier to proceed calmly.

Support after the start of operation

Before contract, you should also check the support content after the start of operation.

payment is not the end of the introduction, because refund processing, payment confirmation, and error handling occur after you start using it.
If it is difficult to know who to consult in such a situation, the burden on the person in charge is likely to increase.

If you look at the scope of response and contact methods in advance, it will be easier to move in case of trouble and stabilize your daily operations.

As explained in this article, in order not to make a mistake in choosing a payment processing company company, it is important to first clarify your company's sales form, expected sales, fraud risk, and management system, rather than fees or popularity, and to make a decision based on the axis of judging the payment structure that suits your company.
