Know the cost before you write the proposal.
Rule of thumb: one subscription seat costs less than paying per project once your firm runs more than 8 Commercial Scale, 6 Development Scale, or 5 Basin Scale projects a year.
One predictable number for your whole firm
Limited time · through October 30, 2026
50% off
50% off your first payment - your first month, or your first year if you prepay. Start your trial below and the code is already on it.
Prepay the year and the code takes 50% off the whole year.
14-day free trial on every firm's first subscription - nothing is charged until it ends or you generate a Technical Report on a covered project. 12-month term, billed monthly or prepaid for the year at 5% off. Prefer invoicing? Reach out to us here. Code TRY50 takes 50% off your first payment through October 30, 2026 - your first month, or your first year if you prepay. After that the plan renews at its regular price.
Every plan includes
- Unlimited projects up to your plan's acreage ceiling
- Submittal-ready Technical Reports - no per-project fees
- Runs in the browser - nothing to install, nothing tied to one machine, your whole firm on the same project from any office
- Projects never expire while your subscription is active
- The same full methodology as every per-project tier
Good to know
- Seats are floating, not named. A seat is one person working at a time, not a license tied to a desk. Three engineers who work at different hours can share one seat; three working at once need three.
- Bigger project than your plan? Buy it per project at 15% off the published price once your trial has closed. The rest of your portfolio stays on the plan.
- Ceilings are inclusive. A 60.00-acre project fits the Development Plan.

Good to know
- 9 months to work in it. Every purchase includes 9 months of full access from activation - revise the design and generate Technical Reports the whole time. Every report is yours to keep.
- Need longer? Re-open the project any time for half the current tier price and get a fresh 9 months. Projects covered by a subscription never expire.
- Have a subscription? Subscribing firms pay 15% less on every per-project purchase once their trial has closed.
- Tiers set the price, not the rigor. Every tier runs the full methodology - classification, Appendix N and O, BMP routing - and produces the same submittal-ready Technical Report.

Price Your Proposal With Confidence
Your SWMLabs cost is a line item on the client's project, not overhead your firm absorbs. Here's how it works:
Step 1
Run a free Site Check
Get your tier and a firm price up front, before you're under contract.
Step 2
Build it into your proposal
A known number goes straight into your project cost estimate.
Step 3
Activate your project
When the proposal is signed, come back and activate the project from your Site Check results.

Really like how straightforward the BMP input sections are and how it shows the removal clearly as you edit them.
