To Get Started
Why I built this
Zachary Reshetar, founder of Boltstrike, on the jobsite
ZACHARY RESHETAR
Founder & Foreman

I DIDN'T LEARN THIS IN AN OFFICE.
I LEARNED IT IN THE TRENCH.

I've spent my whole life on jobsites — swinging the hammer, running the crews, and doing the estimates at the kitchen table long after everyone else clocked out. I've run my own renovation company and led jobs for some of the biggest builders in the business.

And everywhere I went, it was the same thing: a job is won or lost before the first nail goes in. I watched big builders with every tool money could buy still hand their crews software made by people who'd never priced a job or chased down a deposit.

So I built the tool I always needed: the discipline of the big builders, without the bloat that kills the work. Fast estimates. Clean proposals. A deposit schedule that matches how you actually get paid.

The other guys made software for contractors. I built it as one.

FAQ

Questions?
Answered.

Do I need to download or install anything?
No. Boltstrike opens right in your browser at boltstrike.app — nothing to install. On your phone, add it to your home screen from Safari or Chrome and it launches just like a regular app.
Does it work without internet on the job site?
Yes. You can build estimates and export your Excel workbook with no signal at all. Your work stays on your device and syncs back up once you’re online.
What devices does it work on?
Any phone, tablet, or computer with a browser — iPhone, iPad, Android, Mac, or PC. It’s built mobile-first, so it works the same in the truck as it does at the desk.
Can I use my own cost codes?
Absolutely. Rename, add, reorder, or delete any code or category to match your company’s system, then export your code library and load it on any of your devices.
Is there a free trial?
Yes — every plan starts with a 3-day free trial. You’re not charged until day 4, and you can cancel anytime before then. Plans start at $12.99/mo — see the pricing below.
Can I cancel anytime?
Yes. Cancel whenever you want and keep access through the end of your billing period. No long-term contract, no cancellation fees.
Can I send estimates to my clients?
Yes. Export a clean Excel workbook or PDF, or share straight from your phone. Your client just receives the file — they don’t need an account or the app.
Is my data safe?
Your connection is encrypted, and Boltstrike has backup & restore built in so your estimates aren’t stuck on one device. You stay in control — export or delete your data anytime.

Still have a question? Email support@boltstrike.app — a real person (the founder) gets back to you.
