dont forget sales tax even if you dont charge it on your jobs of say
iots tax exempt theres still paperwork to do, the sales tax license
allows you to avoiid paying sales tax on stuff you buy

Yes, if it is for resale or for use in manufacturing. Not everything
qualifies. The MA DOR does audit businesses also so keep those receipts.
It may be cheaper to pay the tax on materials and not charge tax for your
labor and avoid having to do the reports. Check the state laws to be sure
you are doing it correctly.
