For environmental consulting firms
The workflows you run every week — not generic compliance software.
SWPPP inspections, CEQA comment periods, Phase II deliverables — each with milestones, gates, and a deliverable at the end. Mainstay ships them pre-built so day one is not configuration.
Start from a template, not a blank project
Pick SWPPP, CEQA, Phase I/II, or another flow. Milestones and deliverables populate automatically. Name the project, set the site, and the structure matches how your firm already runs the work.
Clients stay looped without chasing
Send for review with a magic-link. Client signs off on their phone. You see it the same day — no account creation, no 'can you log into the portal' conversations.
Finish with proof and a billing signal
Delivery goes on record with a timestamp. Invoice readiness surfaces when the loop closes. One project path from kickoff to cash — without living in email.
Common questions
Can I use Mainstay for stormwater, SWPPP, or Phase I/II ESA projects?
Yes. Mainstay works for any compliance document delivery — SWPPP, SPCC, Phase I/II ESA, RI/FS, remediation reports, CEQA documents, DTSC submittals, and more.
Do my clients need to pay or sign up for anything?
No. Clients open a magic-link in one click — no account, no password, no charge. You stop resending final PDFs and wondering which version is official.
What regulatory feeds are included?
Live California data from CARB, CalEPA agencies, CalGEM, CIWQS, and EPA ECHO — the agencies California environmental firms actually file with.
