It's not just a website. They were merging at least three different enterprise level backend plus deploying the front end to thousands of locations. That's a gigantic effort.
Large companies do pay software vendors to fly out and deploy new browser based software at their locations. Deploying means training staff, hardware integrations, etc. I’ve had several clients over the years request this. If you have someone willing to fly out to do it for a fat bonus check, why not?
