Is there a way of incorporating bitcoin into payment gateways, such as PayPal, Sage etc???

Not into those but there are various ways to run them side by side. Here's a comment that I just made the other day with regards to a different use case but it's also valid for your question:
^{- Since you're not going to use it in a brick-and-mortar store, then ignore what I said in regards to Blockonomics needing a workaround.}

I'd recommend going with either "Blockonomics ^{[easy to set up but depending on how you want to use it, it may require a workaround of some sort]}" or "BTCPay ^{[it takes longer to set up but you'll be in full control]}".
^{- Other options: Bitcoin Payment Processors}

The only problem with that is you have to always update the prices because it is volatile and minor change in the market could be a profit or a loss for your company.

The above gateways would easily take care of that part.
