Simple pricing for stormwater teams that outgrew spreadsheets.

Most small Phase II programs start with the Guided Pilot ($999 / 60 days, up to 3 users) when they want to confirm fit before committing to an annual plan, or with Small MS4 Essentials ($1,499 / year, up to 2 users) when one or two staff just need a structured workspace for inspections, IDDE, and reporting evidence. Programs with a larger field team move up to Inspection Starter ($3,499 / year, up to 5 users). The Full Municipality Pilot ($2,500 / 90 days, up to 8 users) is the right starting point when more of the program — multiple inspectors, complaints, and reporting evidence — needs to go in together. Not sure? Email admin@npdestracker.com and we'll point to a fit.

Both. Guided Pilot, Small MS4 Essentials, and Inspection Starter can be purchased by card or ACH through Stripe. Municipalities that need an invoice, purchase order, W-9, or short order form can request one before payment by emailing admin@npdestracker.com — Stripe invoice (PDF, payable by card or ACH) or a letterhead invoice, net 30 by default. Full Municipality Pilot, Inspection Team, and Full MS4 Platform are invoiced or quoted around the program; a short order form is provided with the invoice.

Online self-service purchases include a 30-day satisfaction guarantee. If NPDESTracker is not a fit, email admin@npdestracker.com within 30 days of purchase. Refunds may be limited or unavailable after paid setup, bulk import, custom configuration, custom implementation, or substantial production use has begun. Quoted plans and Full Municipality Pilot follow the refund terms in their order form or invoice. Full refund policy is on the Terms page.

No. Annual subscriptions do not auto-renew. We email a renewal invoice 30 to 45 days before your anniversary so the agency can decide whether to continue, and there is no penalty for non-renewal beyond loss of workspace access after the subscription period ends. The 60-day Guided Pilot and 90-day Full Municipality Pilot are time-boxed evaluations and also do not auto-renew; we email near the end of the term about continuing on an annual plan. Quoted plans follow the renewal terms in their order form. Full policy on the Terms page, Section 12.

After checkout, you'll continue to workspace setup. Submit your agency details — municipality, plan, primary contact, permit framework, and the workflow you want to start with — and NPDESTracker starts the workspace and sends the admin invite email. From there, the admin sets a password and lands in the workspace setup view. Records export as CSV and, where applicable, GeoJSON on every tier — records stay yours when the relationship ends.

Guided Pilot, Small MS4 Essentials, and Inspection Starter are self-service plans with email and ticket support during business hours. Phone calls, live meetings, done-for-you configuration, bulk data migration, custom implementation, and custom engineering are not included on these plans unless purchased separately or listed in an order form. Full Municipality Pilot includes a founder-led kickoff. On Inspection Team and Full MS4 Platform, founder-led support is coordinated through the agency's designated project lead. Additional onboarding, training, imports, or configuration work can be scoped separately. We do not offer 24/7 support or phone-line support on any tier.
