Sign inMagic Quote for building subcontractors
Describe the job. Get a bid-ready quote.
Skip the enterprise bid-management platform. Describe the scope in plain language and Magic Quote pulls out the line items and prices you mentioned, then hands you an editable quote or change order — sendable for a real e-signature in the same document.
e.g. “Change order for the Miller job — additional outlet run, $180 materials, 3 hours labor at $75/hr”
Free on every plan, including Free. No credit card required.
How it works
1. Describe the job
A sentence or two — the scope you're quoting or the change order, quantities, and the prices you already have in mind.
2. Review the line items
Edit descriptions, quantities, prices, and tax rate — sales tax rules vary by state, so you're always in control of what goes on the quote. Totals recompute live from your numbers, not the AI's.
3. Send for signature
Confirm and it becomes a normal SignedBy document — fields, audit trail, ESIGN/UETA compliant, ready for the GC or owner to sign.
Not another bid-management platform
BuildingConnected, PlanHub, and SmartBid are built for GCs running formal bid solicitations across a big subcontractor network — takeoffs, invitations-to-bid, bid leveling. If what you actually need is to get a fast, professional quote or change order in front of a GC or property owner and get it signed, Magic Quote does that one job, for free, with no setup and no ongoing commitment.
Math you can trust
The AI never calculates a subtotal, tax amount, or total — it only reads the numbers you describe. Every total on screen and in the final PDF is computed by SignedBy's own code, and recalculates instantly if you change a quantity, price, or tax rate.

Does this replace BuildingConnected, PlanHub, or SmartBid?
Not for formal bid solicitation — those are built for GCs running takeoffs and invitations-to-bid across a large subcontractor network. Magic Quote is for the other side of that relationship: turning a plain-language job or change-order description into a proper, editable, signable quote or bid, for free.
Does it handle sales tax?
Set your own tax rate — sales tax on labor and materials varies by state (and whether labor is even taxed at all), so Magic Quote doesn't guess for you. Whatever rate you enter, SignedBy's own code — not the AI — computes the tax amount and total, and recalculates instantly if you edit anything.
Can I use this for a change order, not just a new bid?
Yes — describe the added scope and price the same way, and it becomes its own line-item document ready to sign. Many subs use Magic Quote specifically for the fast-turnaround change orders that come up mid-job, where a full re-bid process doesn't make sense.
Is an e-signed quote or change order legally binding?
Yes — under the U.S. ESIGN Act and UETA (adopted in nearly every state), an electronic signature carries the same legal weight as a wet-ink one, backed by a timestamped, IP-logged audit trail SignedBy records on every document. This is general information, not legal advice for your specific situation.
What plan do I need?
None — Magic Quote is free on every plan, including Free. Sending the finished quote for signature follows the same document limits as any other SignedBy document (3/month on Free, unlimited on Starter+).
Does it work in Spanish?
Yes — English, Spanish, French, German, Portuguese, Dutch, and Italian are all supported. Pick a language on the describe step and everything switches, including the quote PDF itself — useful if your crew, your GC, or your customer's first language isn't English.
