ETA: they do actually have work that needs to be done and it is the work this company described.
I work for a specialized contracting company. We were contacted by a property management company asking for a bid on a repair to a Walgreens. My boss went to the store to look and also got contact information for the building owner directly from the store. The property management company stated they will not pay a down payment, and when they pay the invoice it will be Zelle or Venmo only. Obviously a red flag. The contact for the property management saw that we emailed the store owner the estimate as well and just called freaking out. We are fairly certain this is a scam, but we can't find or figure out how exactly it would be. Thanks!
