綠界科技（ECPay）是台灣常見的第三方金流服務平台，其交易手續費主要依照不同付款方式而有所差異。對於一般會員（包含個人賣家與商務用戶）而言，平台會依每筆交易收取一定比例或固定金額的費用。根據官方公告，自2025年4月1日起部分費率進行調整，目前主要的金流交易手續費大致如下。

在信用卡付款方面，若使用國內信用卡，平台會收取每筆交易金額的2.75%作為手續費，且每筆最低收費為5元。若消費者選擇ATM虛擬帳號付款，手續費則為交易金額的1%，每筆最低收取15元。若使用超商代碼繳費，每筆會收取固定30元的費用；而超商條碼繳費則為每筆15元。至於行動支付方面，Apple Pay也已納入收款方式，並預計自2025年4月1日起全面開放相關收款功能，實際費率仍需依綠界官方最新公告為準。

需要特別注意的是，上述所有交易手續費皆為未稅價格，在結算時還需要額外加計5%的營業稅，因此商家在計算實際成本時應將稅金一併納入考量。

除了每筆交易所產生的手續費之外，使用綠界金流服務時也可能出現其他相關費用。例如當商家將綠界帳戶中的資金提領至非永豐銀行的銀行帳戶時，平台會收取每筆15元的跨行提領費。如果帳戶屬於特定合約方案，或長時間未使用，也有可能產生帳戶管理費，部分案例每月約為500元，實際情況仍需以商家與平台簽訂的合約內容為準。

另外，許多商家也會搭配綠界的電子發票服務。一般新用戶在第一年通常可以享有一定數量的免費開立額度，例如約20,000張電子發票。若超過免費額度或進入第二年使用期間，則可能需要支付額外的年費或服務費。

整體而言，綠界科技的收費結構主要由「交易手續費」與「附加服務費用」兩部分組成。對於電商或線上商家而言，在導入金流服務前先了解不同付款方式的費率與可能產生的附加成本，能夠更準確地評估營運成本並選擇最適合的收款方式。

ECPay is a widely used third-party payment service provider in Taiwan. Its transaction fees vary depending on the payment method used. For general members, including individual sellers and business users, the platform charges a certain percentage or a fixed fee for each transaction. According to the company’s official announcement, some rates were adjusted starting on April 1, 2025. The main payment processing fees are generally structured as follows.

For credit card payments made with domestic cards, the platform charges a transaction fee of 2.75% per transaction, with a minimum fee of NT$5. If customers choose to pay through an ATM virtual account transfer, the fee is 1% of the transaction amount, with a minimum charge of NT$15 per transaction. For convenience store code payments, a fixed fee of NT$30 is charged for each transaction, while convenience store barcode payments cost NT$15 per transaction. In terms of mobile payments, Apple Pay has also been included as a supported payment method, and its full payment collection function has been available since April 1, 2025. The exact processing fees for this method should be confirmed through ECPay’s latest official announcements.

It is important to note that all the transaction fees mentioned above are quoted before tax. During settlement, an additional 5% business tax must be added. Therefore, merchants should take the tax component into account when calculating the actual cost of using the service.

In addition to transaction fees, there are several other potential costs associated with using ECPay’s payment services. For example, if a merchant withdraws funds from their ECPay account to a bank account that is not with Bank SinoPac, a cross-bank withdrawal fee of NT$15 per transaction will be charged. In some cases, accounts tied to certain contract types or those that remain inactive for a long period may also incur an account maintenance fee. In some situations, this fee may be approximately NT$500 per month, although the actual amount depends on the specific contract terms between the merchant and the platform.

Many merchants also use ECPay’s electronic invoice service. New users typically receive a certain number of free electronic invoice issuances during the first year, often around 20,000 invoices. If the number exceeds the free quota, or once the first year has passed, merchants may need to pay an additional annual fee or service charge.

Overall, the pricing structure of ECPay mainly consists of two components: transaction processing fees and additional service-related costs. For e-commerce businesses and online merchants, understanding the fee structure of different payment methods and the potential extra charges in advance can help them more accurately estimate operating costs and select the most suitable payment solutions.
