Petty Cash for Field Personnel

I'm in the transition process with my acquired company and am trying to find a solution for my field personnel to have "petty cash" for small purchases. While I'm in the process of getting credit cards for the company and fuel cards for the fleet, I was considering a reloadable pre-paid debit card option for the field personnel. Has anyone used a service like Dash prepaid that they would recommend? I would like something that integrates with QuickBooks Online and I can control and monitor the spending across the team. Company credit cards may be the solution in the longer term but with the new entity making it a bit tougher I'm thinking that this may be a solution in the interim.
