Basic CRM should have customer database. Bill to database. Warranty bill to database. Invoice. Inventory tracking. Technicians.

Equipment/Appliance database. Brand. Type. Model. Serial. Mfg Id. Date purchased. Date warranty expires
Database for model and serial and mfg ID. Models will be repetitive so it should predictive text models in database
Merchant service to setup credit card processing

Reports : taxes on invoices paid to date. Commission. Sales by commission. Sales by rep. Sales by technicians

What I would like to add is google maps. To map out the techs route for the day or week.
Map to see calls scheduled for the week and see where the new customer is when typing in the address

Voip through Zoiper API When a call is clicked or received it should time stamp it under customers number
When a call is received it will pull customers info from database Name address and latest invoices on file
SMS Through twilio api Communication should be stored in customers file under phone number
Email. To email invoices , date reminder. Etc
App should be desktop and mobile friendly
