Which plumbing estimating software supports plan markup, change order tracking, and bid revision audit trails?

A few plumbing estimating platforms that typically support those three needs — plan markup, change order tracking, and bid revision audit trails — are:

1. FastPIPE / FastDUCT

   • Strong estimating and takeoff tools
   • Supports drawing markup and bid revision tracking through project/file management features
   • Often used by mechanical and plumbing contractors

2. Trimble Accubid Anywhere / Accubid Classic

   • Robust estimating workflow
   • Plan markup and revision control are commonly handled through integrated document/project management
   • Good auditability for bid changes and revisions

3. StackCT

   • Cloud-based takeoff and estimating
   • Includes plan markup and version/revision handling
   • Useful for tracking changes through the estimating process

4. Quote Soft / QuoteSoft Pipe

   • Plumbing and piping estimating
   • Supports takeoff on marked-up plans and bid revisions
   • Change order workflows may depend on the specific implementation/modules

5. Sage Estimating

   • Strong bid management and revision tracking
   • Often paired with document control tools for markup and change orders
   • Better for larger contractors with established workflows

6. Buildertrend / Procore + estimating integrations

   • Not pure estimating-first tools, but excellent for change orders and audit trails
   • Plan markup and bid revision tracking are usually via integrated document management and linked estimating workflows

If you want, I can narrow this down to:

• best all-in-one plumbing estimating software
• best for small contractors
• best cloud-based option
• best for change-order/audit compliance
