Questions about plans
Is the calculator really free?
Yes. The public calculator needs no account and has no limit. It gives a first estimate from your bill using reviewed KPLC tariffs.
What is a full calculation?
In the workspace, planning previews update as you type and are unlimited. A full calculation is the saved, versioned result that reports are built from. Free includes 3 a month; reopening a saved result does not use another.
How much does Pro cost?
KES 250 a month for your whole team while StimaPulse is in testing. Each payment covers one month and does not renew automatically. The calculator and the Free plan stay free.
How do I pay for Pro?
Choose Get Pro and pay by M-Pesa through Tihada. You get a prompt on your phone. Enter the email you want to use for StimaPulse; if you already have a workspace, use the email you sign in with. New customers get a private invitation by email to set a password and name their organization. Once payment is confirmed, Pro is switched on for your whole organization.
What happens if Pro expires?
Your organization moves back to the Free allowances. Saved projects and results stay available.
Does the plan change the accuracy of results?
No. The calculations are the same on every plan. Pro adds capacity, professional reports and the tools you need when preparing to buy.
How do I get a workspace?
Sign in if your organization already uses StimaPulse. If not, join the waitlist from the sign-in page or talk to us, and we will set up access for your business.
