Systems &Processes Used to Pay Vendor Invoices Across Multiple Properties & Entities

[Chico Ford]

We own several properties that our company self manages.  These properties are located in other states in smaller towns and span multiple legal entities and bank accounts.  Many of our vendors request payment same day as the work is completed.  What systems and processes are you using to pay these vendors?  I don't want to hand our onsite property manager checkboooks to pay these invoices.  Any advice would be greatly appreciated.
