The free trial for the Stash Premium Plan can be set up through self‑service. To upgrade to the Enterprise Plan or make changes to your subscription, please contact the sales team.
Stash uses a manual invoicing process for all plans. Invoices are sent to the billing contact email on file and include full payment instructions. Payments can be made by credit card or bank transfer following the details provided on the invoice. While credit card payments are supported, there is no self‑service payment portal. You can view your current plan and all past invoices at any time from the Billing & Invoices section in the Stash web app.
