How to Run a Successful Window and Glass Company
Seven money habits we see separate steady window and glass companies from stressed ones.
Bid from real material costs
Custom glass and windows carry long lead times, so price from current supplier costs.
Take deposits for custom orders
A deposit covers special-order materials so you are not financing them yourself.
Track materials to jobs
Tag every supplier invoice to a job so costs are not lost.
Review profit job by job
Look at margin when each job closes and adjust pricing on the ones that miss.
Keep business and personal money separate
One business account and card per company makes your books accurate and your taxes simpler.
Keep subcontractor paperwork current
Get a W-9 and certificate of insurance before the first payment.
Set cash aside for payroll and taxes
Move money into a separate account as you earn it so payroll and tax bills are never a surprise.
