-- IMS system for co-ops.
 
-	- to own the means of production we also need to own the software
+## Motivations
-	- community ownership of the infrastructure that powers it is important for stability
+- to own the means of production we also need to own the software
-	- needs to support customer and worker co-ops
+- community ownership of the infrastructure that powers it is important for stability
-	- federation of co-op systems
+- needs to support customer and worker co-ops
+- federation of co-op systems
+- member only co-op are how small businesses should exist in a community
+
+## Design Requirements
+
+### Crawl
+- Member only co-ops
+- Handle looking up products
+	- SKU numbers
+	- PLU numbers
+	- UPC numbers
+- Non fixed quantity products
+	- what units do we use
+- IMS and POS system need to be able to operate independently
+- Track orders per account
+- generate inventory reports
+- Internationalization of UI
+	- Accessability for users of all backgrounds
+
+### Walk
+- inventory velocity reports
+- opt in item location lookup
+- integration into other systems to order supplies
+- track costs vs revenue
+	- broken down store wide
+	- broken down per member
+- accept payments for items
+	- cash
+	- multiple currencies?
+	- crypto???
+
+### Run
+- federation
+- Single Sign On
+- accept card payments for items
+	- the big processors
+	- whats europe doing nowadays
+	- SNAP/EBT
+- Product requests
+
+### Fly
+- nix config with a software suite that sets up all of the systems (POS, IMS, auth, member matrix server)
+
+## Design plan
+
+systems:
+
+- card payment bridge
+	- talking to credit card readers is complex and needs drivers. We should make some kind bridge software that runs on a very very cheap device like a pi or something.
+- payment system
+	- payment module should be separate from point of sale module so we can keep the concept of pricing as separate as we can
+	- track cost of items
+- point of sale system
+	- in charge of tracking what items are a part of what order
+	- requests preview information from payment module
+	- forwards order session to payment system
+	- send completed orders to inventory management system
+- inventory management system
+	- track what is in stock
+		- track estimation of how much product exists
+		- track shrink rates
+		- track product velocity
+	- get messages from point of sale system to update inventory amounts
+	- handle audits
+- finances system
+	- track revenue vs expenses
+	- forecast budget
+- authentication system (how do we track member id numbers relating to this?)
+- web portal
+- matrix server
