Hello! Yes, we have Wordpress developers here who can help you with your questions about Payment Gateway integration.
Regarding your inquiry, the requirements for integrating a Payment Gateway like Paypal or Card Payment on your e-commerce website do not typically include being registered with the DTI/BIR. However, it is essential to have a legal business entity to operate an e-commerce store and process online payments. It is recommended to register your business with the appropriate government agencies once you are ready to launch your online store officially.
In terms of submitting business documents to integrate a payment module, most Payment Gateway providers will require you to provide certain details about your business, such as your company name, address, contact information, and bank account details. Some may also request additional documents like a business registration certificate or a bank verification letter.
Since your business is still in the testing stage and unregistered with the DTI/BIR, you can explore using payment gateways that do not require extensive documentation for integration, such as PayPal's standard business account or Stripe. These options are more straightforward to set up and can be a good starting point for your e-commerce venture.
If you are looking for other suggestions, you may also consider using WooCommerce as your e-commerce platform since it seamlessly integrates with various Payment Gateways and offers a wide range of customization options for your online store.
