Duct estimating software vs. an outsourced takeoff

Dedicated duct and piping estimating software — FastDuct and FastPipe from FastEST, PlanSwift, Trimble's mechanical products and others — has been around a long time and is built by people who understand the trade. If you have used one and liked it, this page probably is not for you.

What you are actually choosing between

Software sells you capability. A service sells you output. Both cost money; they cost it differently.

	Duct estimating software	FlowLogic Estimating
The purchase	A license, usually annual, often per seat	A flat price per plan set
Time to first takeoff	Install, configure, learn, build your item database	Send a link
Who counts the fittings	You, with better tools	Us
Cost in a slow quarter	The same	Zero
What you own afterward	The tool and the setup work you invested	The takeoff

The setup cost people forget

The license is the visible number. The invisible one is configuration: your material list, your labor units, your gauge and seam rules, your fitting library. Getting a duct estimating package properly dialed in for one shop is real work, and it is usually done by the person who can least afford the hours.

That investment pays back if you bid enough. It is dead weight if you bid twelve jobs a year.

Where the software is the better buy

• High, steady bid volume. The license gets cheap per job in a hurry.
• A dedicated estimator. Somebody who will get fluent and stay fluent.
• You need it tied into fabrication. Several packages feed downstream shop systems. If you use that, it is a real advantage a service cannot match.
• You want the estimating knowledge to live in your shop. Tools are how that knowledge gets institutionalized.

Where this makes more sense

• You bid in bursts and the license sits idle between them.
• You are the estimator and the owner and the one answering the phone.
• You want to know what a takeoff on a specific job costs before committing to a year.
• You have software already but are past capacity this bid season and need overflow help.

That last one comes up more than people expect. Using a service alongside software is not a contradiction — it is how you catch a busy month without hiring.
