How do I bill I bid properly and keep my inventory right?
So, let’s say I install a minisplit, and I’m an electrician,
I buy parts in bulk for electrical so my inventory is important, and I install the parts and send the customer a bill for labor and materials, no break down. Just match the signed bid amount.
Once the job is paid I will just delete the labor and materials lines and add the actual labor costs and actual materials used and then a line that shows my profit, but the customer can see the invoice once I edit it? So I usually just end up making a new one
Anyways, this is annoying because so many of my customers and filing rebates for these mini splits and they want a copy of the invoice, but I have already voided the thing and replaced it with one that tracks my inventory and breaks down the actual costs.
How do I do this better?
