Duration is a client decision, not a plan tier
Most software is sold in tiers: monthly, annual, sometimes a discounted two-year lock-in. We took a different approach with EMS and HMS. Each product has a single, transparent rate — priced per day — and the client decides how many days to buy at purchase or renewal time. There's no "Starter" or "Enterprise" plan hiding what you actually get; the rate is the rate, and duration is entirely your call.
How the wallet actually works
A client funds a wallet — through a dedicated virtual account generated specifically for their organisation — and every purchase or renewal is a straightforward debit against that balance. Buy 30 days of EMS today, and you're charged exactly 30 times the daily rate. Need to extend an already-active licence before it expires? The extra days simply stack onto the existing expiry — you never lose paid-for time by renewing early.
Why we did it this way
Institutional budgets, especially in education and healthcare, rarely align neatly with calendar-month subscription cycles. A school might want EMS active specifically for a testing window and inactive otherwise. A hospital's clinical advisory board might want HMS running continuously with no thought given to renewal dates at all, via auto-renew. Per-day pricing with a spendable wallet lets both of those be the same underlying system, not two different products.
Every transaction — top-ups, purchases, renewals, and any manual adjustment — is recorded permanently in a full statement, so "what did we actually pay for and when" is never a mystery months later.
