Thank you, sir! Exactly the sort of breakdown we need!
The $100K figure has a sort of built in economy of scale for a 7-store local franchise chain. $30K of it is the server (and I am assuming that includes all software and support costs). That still means about $10K per store of individual hardware costs. The per store cost is about $17K if a central server is required. This is where the SaaS/cloud model will look much more attractive! Let somebody else worry about maintaining the vital central server; outsource the problem to experts!
Single store FIRMS cost is (hypothetically)
sign up costs = $2000
plus maybe 5 iPads= $2500
wifi router or three = $500 (plan for redundancy, we may need repeater for the back partyroom, etc.)
a wireless printer = $500 (if you throw in a year of ink?).
We are up to less than $6K hardware cost, about half of the single store hardware costs excluding server and software for your client, less than a third if the full distributed server-based system cost is figured.
We can even afford a nice laptop for the manager's office, a kitchen terminal to receive orders (if it is not an additional ipad serving this role) and a wifi-connected desktop for the hostess desk up front to manage reservations, and still be way ahead of the hardware costs of your hardwired POS system.
If we assume the hostess carries an ipad and phone to manage the reservations, then the additional terminal up front can be eliminated.
When you add in the economy of scale for multiple business locations included under the initial $2K signup fee, it gets even cheaper per store!
The only remaining question: how soon will the restaurant owner be getting his yacht? ;-)
