Why these are free
SpoilStack is $99 a month, flat, unlimited users. It keeps the job record after the bid: machines, haul counts, daily logs, extra work tags (T&M), rain delays, photos, plans, and closeout backup. These free tools do one piece of that by hand.
If you use them and want the rest, start a free 14-day trial.
Frequently asked questions
Are these tools really free?
Yes. Every calculator, generator, and checklist on this page is free to use with no signup, no email, no watermark, and no usage limits.
Do you store my data?
No. Anything you type stays in your own browser using local storage on your device. It is never sent to a server or saved to an account.
Do I need an account to use them?
No. There is nothing to sign up for. Open a tool, fill in the form, and download or print the result.
What is the difference between the free tools and the SpoilStack app?
The free tools each handle one task by hand, like a single haul ticket or volume estimate. SpoilStack is the paid app ($99 a month flat, unlimited users) that keeps the whole job record between bid and closeout: jobs, machines, haul counts, daily logs, plan markups, photos, documents, and branded closeout packages, all offline-first and synced across your crew.
Can I use the tools on my phone?
Yes. The tools work in any modern mobile or desktop browser, so you can use them in the field from your phone or tablet.
