Digital Change Orders is a mobile-first tool that lets contractors create, send, and get change orders signed โ€” right from the jobsite.

The Problem

Change orders are one of the biggest sources of payment disputes in the industry. Contractors do extra work based on verbal agreements, then clients deny agreeing to the price. The paperwork process is slow enough that most contractors skip it when they're busy - which is exactly when they need it most.

How It Works

  • Create a change order in under 2 minutes from your phone
  • Describe the change, set the price, and send it for approval instantly
  • Collect a digital signature on-site before any extra work begins
  • Every change order is timestamped and stored automatically

Who It's For

General contractors, remodelers, subcontractors, and specialty trades who want to stop losing money on undocumented scope changes. Whether you're running one job or five, Digital Change Orders makes sure every change is documented and signed before work starts.

Why It Matters

No signature, no work. That's the rule that protects your margins. Digital Change Orders makes following that rule fast enough that there's no excuse to skip it - even when you're running between jobsites.

Questions & Answers

As answered by people managing SQLZOO and Digital Change Orders.

What makes your product unique?

Digital Change Orders's answer:

Most change order tools are buried inside massive project management platforms that cost $50-300/month and take weeks to learn. Digital Change Orders does one thing and does it fast - create a change order, price it, send it, and get it signed, all from your phone in under 2 minutes. No training, no bloated features, no app download required for the client signing it.

Why should a person choose your product over its competitors?

Digital Change Orders's answer:

Competitors like Procore, Buildertrend, and CoConstruct force you to buy an entire project management suite just to handle change orders. Digital Change Orders is purpose-built for the moment you're standing on the jobsite and the client says "can you also do this?". You pull out your phone, write it up, get their signature, and the work is documented before you pick up a tool. It's faster, simpler, and cheaper than any alternative.

How would you describe the primary audience of your product?

Digital Change Orders's answer:

General contractors, remodelers, subcontractors, and specialty trade contractors - especially small-to-mid-size companies running residential and light commercial projects. These are builders who don't need a $200/month platform but can't afford to keep losing money on undocumented scope changes.

What's the story behind your product?

Digital Change Orders's answer:

Built by ex-contractors who have lost thousands on verbal change agreements that clients later denied. The "I'll write it up later" approach doesn't work - later never comes when you're juggling multiple jobsites. Digital Change Orders was created to make the documentation process so fast that there's no excuse to skip it, even on your busiest day.

Which are the primary technologies used for building your product?

Digital Change Orders's answer:

Web-based application built for mobile-first use. Works in any browser on any device - no native app installation needed. Digital signatures are collected and timestamped electronically.

Who are some of the biggest customers of your product?

Digital Change Orders's answer:

  • Independent general contractors
  • Residential remodeling companies
  • Specialty trade subcontractors
  • Custom home builders
