Getting started

Last updated: 2026-05-19

This guide takes you from a fresh sign-up to a sent WhatsApp invoice in about 5 minutes. Have your latest KPLC bill SMS open on your phone before you start — you'll need the rate from it.

1. Sign in

  1. Go to stimafy.online and tap Start free.
  2. Sign in with Google. We don't store passwords — Google handles authentication and we only get your name and email.
  3. You'll land on the dashboard. It'll show a setup checklist if this is your first time.

2. Add your first property

  1. From the dashboard, tap + New property (or Properties → + New property).
  2. Give it a name (e.g. Kileleshwa Flats), an address (for your own reference), and your KPLC main meter number if you have it handy. Only the name is required.
  3. Tap Create property.

Free plan limit

The free plan covers one property. If you manage more buildings, reach out via Talk to us and we'll quote a paid plan based on your portfolio.

3. Add units

Inside your property, the Units section lists each rentable unit. For each one:

  1. Type the unit name (e.g. Unit 4B, House 1).
  2. Optionally add the sub-meter number — useful if you have several meters that look alike.
  3. Tap + Add unit. Repeat for every rentable unit.

4. Add tenants and assign them to units

  1. Go to Tenants → + New tenant.
  2. Enter the tenant's name, phone number (in international format like 254712345678 — required for WhatsApp invoices), and email if you have it.
  3. Save the tenant.
  4. Go back to the property page, find the unit, tap + Assign tenant and pick the tenant from the dropdown.

The first assignment can take 10-30 seconds while the database wakes up. You'll see an "Assigning tenant…" spinner while it's working.

5. Start a billing cycle

  1. Go to Readings. Tap + Start a cycle.
  2. Paste your latest KPLC bill SMS exactly as you received it (BillDate, CurRead, Units, Bill, Pay…). Stimafy extracts the rate automatically — usually around KES 28-32/kWh depending on the month.
  3. Confirm the parsed values and create the cycle.

See Recording meter readings for the details of what the SMS parser looks for.

6. Enter sub-meter readings + send invoices

  1. Open the cycle. For each unit, enter the previous and current sub-meter readings. Stimafy shows you the kWh used and the resulting bill in real time.
  2. Tap Save. The bill auto-creates as a draft.
  3. Go to Invoices. For each draft bill, tap Send via WhatsApp. WhatsApp opens with the message pre-filled. Hit send.

That's it. When payment lands, tap Mark paid. Outstanding bills get a Send reminder button — a shorter, friendlier follow-up message.
