zigndoc's value prop in one sentence: stop losing deals because contracts didn't get signed in time.

had a contractor tell me he used to lose 2-3 days waiting on signed contracts. with zigndoc it's same-day 90% of the time. that's the ROI story i'm trying to tell.

a user told me they stopped losing deals because contracts weren't getting signed in time. zigndoc sent the reminder, the client signed, work started the next morning.

Still building Zigndoc for a narrow use case: contractors who need a clean way to send agreements, collect signatures, and keep signed PDFs in one place.

Zigndoc update: working on template support so contractors can reuse agreement structures without recreating them from scratch every time.

Building Zigndoc in public — a simple e-signature tool for contractors to upload PDFs, send signing links, collect signatures, and keep signed documents organized without the usual complexity.

what i've learned building zigndoc: contractors don't care about technology. they care about getting the job approved and starting work. technology is just the invisible layer that makes that happen faster.

zigndoc is live at zigndoc.com. if you're a contractor and your current process is emailing PDFs and waiting forever, give it a try.

Zigndoc is getting closer to the kind of product I want it to be: focused, simple, and useful for real contractor paperwork instead of bloated with random features.

got a DM asking if zigndoc works for landscaping contracts. yes. fencing quotes. yes. HVAC service agreements. yes. if it's a PDF a contractor needs signed, it works.

Zigndoc was built for the contractor who's tired of emailing PDFs back and forth and chasing physical signatures. Digital should be faster, not more complicated.

someone signed a zigndoc document on their phone while sitting in a client's driveway. that's exactly the use case i built it for. outdoor, mobile, fast.

zigndoc is free to try. no credit card. no setup. upload a PDF, send a signing link, see how it works. if it doesn't work for you, i want to know why.

zigndoc's growth channel right now is word of mouth between contractors. one uses it, tells another on a job site, they sign up. that's the distribution i'm betting on.

had a contractor tell me zigndoc saved him an hour on a job site because he didn't have to drive back to the office to collect a signature. that's the win.
