Additional Pro sites
An additional site is available only to an active Pro account after all included activations in the current billing period are used. Ordinary Pro cancellation stops new paid work but preserves approved completed-result reads and standard exports. Current availability is not currently available.
After purchase
Single Site includes permanent account read access. Ordinary Pro cancellation stops new paid work and Pro-only changes, while completed standard results and standard exports remain available.
Corrections and capacity
Single Site corrections are limited to 30 days after the first durable result, must remain inside the purchased envelope and cannot grow the original area by more than 10%. Pro includes 10 activations per billing period with no rollover.
Not included
Plans do not include a survey, legal parcel record, flood decision, engineering or geotechnical determination, grading quantities, permit approval or a guarantee that detailed elevation exists for every site.
Before paid launch
Paid production sales remain disabled until the final customer terms, seller identity, tax setup, receipts, refund and dispute language, and support procedures are approved and verified.
