I'd like to make a calculator for backend operations in travel industry, which will calculate prices per day, per person, which will allow database to be uploaded. For now, I'm doing most of a manual stuff, which doesn't allow to scale too much.
Existing solutions on the market is expensive and quite heavy to manage, need separate manager to upload and monitor every details.
What I need is simple solution to build or pay to use?
Any ideas? Please share.
