In most cases, Let’s Encrypt certificates provide the same level of encryption as paid ones. The main difference is the type of validation: Let’s Encrypt only does Domain Validation, while paid certificates can offer Organization Validation or Extended Validation, giving extra “trust” signals (like showing the company name in the address bar). For many e-commerce sites, that added verification can help reassure customers they’re dealing with a legitimate business. However, if you’re just starting out or have a smaller store, a free certificate can still keep your data secure. The bigger factor is making sure your entire site and payment process adhere to security best practices SSL alone isn’t the whole story. If you feel your brand needs that extra layer of trust, then a paid certificate might be worth it, but you can always start with a free SSL and upgrade later if needed.
