Hello - I just acquired a business, and I have the chance to start fresh with expense reimbursements and want to make the right decisions. What is considered the best "stack" (e.g. rippling, expensify, amex cards). Right now, the company is small (12 employees, 3 individuals with expense cards, ~10k of credit card expenses per month), but my plan is to do a rollup so I want to create a stack that will scale with the company.
