The Missing Link Between Your Estimate and a Signed Contract.
We turn QuickBooks estimates into legally binding, e-signed contracts for service businesses—automatically.
The “Accept Estimate” button is not a contract.
7 million service businesses run on QuickBooks. None of them get a legally binding, e-signed contract out of it. Instead, they’re stuck rebuilding one by hand—every single time.
One click. From estimate to signature.
ContractFlow collapses eight disconnected manual steps into a single, automated workflow that lives inside the tool service businesses already use every day.
Auto-Populated Contracts
Pulls customer data and pricing directly from QuickBooks. Zero manual entry, zero copy-paste errors.
ESIGN-Compliant
Legally binding e-signatures with a full, tamper-evident audit trail on every contract.
Industry-Specific Templates
Purpose-built for HVAC, plumbing, electrical, landscaping, and beyond—not generic legal boilerplate.
Admin Dashboard
Track every pending and signed contract in one place, synced back to QuickBooks in real time.
A massive market, hiding inside a workflow nobody else owns.
Niche SaaS outperforms horizontal platforms.
Vertical SaaS companies achieve 35–60% higher customer retention than horizontal competitors, because their products become embedded in daily operational workflows—not just another tab left open.
The only tool built for the QBO-using service business.
Everyone else asks service businesses to change how they work. We don't.

A conservative path to $7M+ ARR within the QuickBooks ecosystem alone.
The QuickBooks ecosystem provides access to ~2.8M service businesses in our primary target segment — construction, IT, and software services. Projections below use conservative conversion benchmarks against comparable niche SaaS tools with strong product-market fit.
These projections cover the QuickBooks ecosystem only. A single unified accounting API connects to 50+ platforms, including Xero, FreshBooks, and Wave — expansion beyond QuickBooks multiplies the addressable market by 3–4x with minimal added engineering.
Not a concept. A live product.
