Seeking advice for payment gateway integration for my online startup offering services and bookings online.
Razor pay is technically very new while PayU has been around for quite sometime. I've shopped on websites using both and PayU was a little more efficient compared to Razor and also integrating PayU does not take a lot of time.
Pay u is doing much better then others....
It's important to take into consideration a few things as a start like which markets are you targeting, how many visitors you are expecting? Then narrow down the choice to a few and then see pricing based on expected volumes, etc. You wouldn't want to end up with a complex integration that would do the job but be a big overhead.
Depending on how you are building your website - custom vs a ready solution, e.g. shopping cart modules, you could use some of the built-in payment gateways.
It's preferable to use Stripe. We've used it. It turns out it has well defined/documented APIs being dev friendly for web/mobile systems.
You should also take a look at Sage Paynent Solutions.
My opinion is going for Pay u. Because Pay u is much better then other payment gateways.
Payu money is doing great work
Whichever solution you choose, make sure your technical architecture allows you to painlessly switch payment gateways in the future. From my experience, it is not uncommon to switch every 1-2 years for cost reasons.
