Honestly, it sounds like you just need a spreadsheet to rope a few bits & bobs together. I'm with Jeff, focus more on what we're attempting to solve, less on the technology. The tech will come along.
That said, I'd rather hand someone an Azure SQL Database backed web page, than an Access backed anything. Yes, they are going to have to pay for Azure (and technically should be paying something for Access). However, they get backups, failover, most of the maintenance done for them, all stuff that you'll need to do in Access on your own, but on a more stable reliable platform.
Still, focus first on what problem you're solving, then find the tech to solve it.
