Electrical Contractor Forms are printed specifically for the electrician and covers all the details of a job. We use 20lb NCR carbonless paper stock with 2, 3 or 4 parts. Forms can be numbered and perforated as required. You also have the option to print as a booklet with 50 invoices per book or they can be printed as individual forms glued at the edge. You can customize your invoice, work order or receipts by adding a logo and your company contact information.
