Hello house, lately I have been thinking of launching a Web based services of which I'm targeting the USA market.. I have been thinking of the best payment gateway that more secure and highly accessible.
If you have been using one before, kindly share your experience, the process involved and the cost of running.

Stripe seems like the no-brainer choice for a US market

Thanks, will check out the requirements

If you're based in Nigeria which i highly presume, you can't open a stripe account
unless you wanna go through the incorporate-me-abroad path, stressful, more money
stripe is living on past glory these days
there are newer tested and trusted coys that favour new entrants in the market e.g
Paddle, ChargeBee and Recurly to mention a few.
Dig deep.
