If you want full control over the payment process to your website you should go for a self-hosted payment processor but note that it would cost you maybe a bit more for hosting and developing if you will hire a developer to do the work, a small business might get hard to maintain those requirements for hosting.
While there are many hosted bitcoin payment processors which give you easier setup, mostly 1-2% charge in every transaction made but will give you less control over your money, especially some requires kyc, btw I recommend Blockonomics.
I advise you to pay special attention to the security parameters of your payment method, namely two-factor authentication. After all, today's market requires reliability, especially in the world of cryptocurrencies, and the 2FA service can help in this as never before. Every year, the
2fa platform should improve and take a leading position, in this regard, Google has succeeded very well with its security algorithms. Today, two-factor authentication solutions act as a universal method for generating one-time passwords using specific security tokens. This raises the problem of multi-factor authentication solutions to a new level, because it is important to have a different security architecture. Universality is the main criterion. if you consider an example of a local 2FA platform using a protective layer and its accompanying tokens, you can achieve a new level of security for your service, which is not a little important when working with cryptocurrencies and especially when providing services.
