try it on one job
Put it on one job. If it isn't better than what you do now, take your money back.
Most shops already do this in-house, on a Sunday, in a spreadsheet nobody else can check. You do not have to change that. Run one job through this instead and compare the output.
$79 USD, one job
One-time. Nothing recurring, nothing to cancel later.
30-day money back
Ask and it is refunded. No reason required, no phone call.
90 days of revisions
Regenerate the document as the job changes, free.
100% credited if you subscribe
Subscribe within 30 days and everything you spent on documents comes off the first invoice.
Trying one job costs you nothing but the time to type in the numbers.

how we treat you
The terms, in full, in plain words.
Your price never increases while you're subscribed
When list prices rise, they rise for new customers. Yours is the price you signed up at, for as long as you stay.
Cancel anytime, in one click
Self-serve in the billing page. No retention call, no notice period, no 'contact us to cancel'.
Refunds are instant and unconditional
30 days on anything you buy. We do not ask why, and we do not make you argue for it.
The calculators are never paywalled
Single-run calculations with their citations are free forever and need no account. That is not a trial — it is the deal.
Public prices, everywhere
Every price is on this page, in USD. No quotes, no 'talk to sales', no discount you only get by threatening to leave.
Your data stays yours
Export your documents whenever you like. Cancelling does not delete your projects or reach back into PDFs you already have.
what this is not
Where the line is.
This is a code-cited electrical documentation package. It is not a stamped plan set, and not an engineer's seal. Where your jurisdiction requires a P.Eng or PE stamp, you still need one.
What an authority having jurisdiction accepts varies by jurisdiction and by reviewer. We do not promise acceptance, and you should be suspicious of anyone who does. You remain the licensed person submitting the work, and every value must be verified against the installed system before it is energised.
Marine outputs cite ABYC E-11 and are marked DRAFT until a licensed reviewer signs off those tables. How we verify our tables.
side by side
What changes between plans.
The calculations are identical on every tier. What you pay for is the deliverable and the workflow.
