How it works

How BidProof reviews your solar proposal

Upload the documents you have, confirm a few details, and get a second read paid for by you — before you sign.

Choose a review and share your documents

Upload your proposal for Bid Review ($49). For Bid + Contract Review ($99 total), send the contract you would sign and the proposal so we can compare them. PDFs, photos, and screenshots work.

Confirm what we read, and tell us what matters

We extract the numbers from your documents and ask you to confirm the important ones. Goals are optional. If you are still deciding what you want from solar, we review the proposal on its face.

Pay, then we run the checks

You pay for the review, then we check the published categories against independent data. Where a check cannot run, the report says “not checked” rather than guessing.

Read the report and take questions back to the seller

You get a plain-language result, findings, and a list of questions. The report is yours to keep or share. It is not legal, tax, financial, or engineering advice.

What you should know up front

Who it is for

Residential homeowners in the United States who have a solar proposal and have not signed — or who still have a cancellation window they can use. We do not review commercial projects, and we do not rank installers.

When information is missing

We run every check we can. The rest are marked “Not checked,” with the information needed to assess them. We explain what we couldn’t check and why, without inventing information to fill a gap.

If you only have the proposal

Start with Bid Review for $49 if you have a proposal. Bid + Contract Review costs $99 total. If your contract arrives later, contact support to arrange its review for $50 more on the same previously reviewed proposal. Contact support.

Plain answers

What documents do I need?

Send your solar proposal for Bid Review. For Bid + Contract Review, include the contract you would sign and the proposal so we can compare them. If you only have the contract, we explain what we could not compare without the proposal. PDFs, photos, and screenshots are fine. An electricity bill is optional but recommended. Upload one recent bill, including its 12-month usage history if shown, to help us check the proposal against your electricity use.

Can I add my contract later?

Yes. Start with Bid Review for $49. If you've already paid for that proposal, email support@bidproof.com when its contract is ready. Include the email address used for your review and your original order or report link. We'll arrange the contract review for the same proposal for $50 more, bringing your total to $99. Contact us before paying for another review, and send the contract before you sign.

How long does a review take?

Automated reviews are completed instantly. If your bid needs a human review, expect your report within 2 business days, usually sooner.

Is this legal, tax, or engineering advice?

No. BidProof is an independent document review. It is not a law firm, and it does not certify a system’s engineering.

Who actually reviews the proposal?

Software runs the published checks against independent data. Plain-language writing makes the result readable. When a review needs a person, an experienced reviewer takes it.

Ready for a second read?

Start with the documents you have. We will tell you what we could check — and what we could not.
