Pay application software for plumbing subcontractors
DrawPrep helps plumbing subcontractors break scope into underground, rough-in, top-out and fixture lines and prepare G702/G703-style pay applications. Inspection records and backup documents stay attached to the period they support.
Billing challenges in plumbing
Inspection-driven milestones
Underground and rough-in are often tied to inspections. Keeping inspection records with the billing makes progress easier to support.
Fixture procurement
Fixtures and specialty equipment may be bought early and stored, which needs its own documentation.
Unit-based jobs
Multifamily work repeats scope across buildings or floors; consistent SOV lines keep that progress readable.

Plumbing billing questions
- How should a plumbing schedule of values be structured?
- Many plumbing contractors organize lines by phase (underground, rough-in, top-out, trim) and by building or floor. Follow any breakdown your GC requires.
- Can I attach inspection reports to a pay application?
- Yes. You can upload PDFs or images to the project and include them in the downloadable package.
- Can DrawPrep track retainage on this kind of job?
- Yes. You set the retainage rate the contract requires, and each pay application carries it forward and flags a rate that changes between periods so you can confirm it before sending.
