Before LettingOS

This is how landlords
track rent today.

It works. Barely.

One ledger.One calendar. One place.

The ledger

Never ask ‘did they pay?’ again.

Every rent payment, reminder, note and upload on one line. Filter by tenant, status, or month. Export a full audit trail to CSV in one click.

  • Paid, pending, or overdue — always at a glance
  • Amount, method, and date on the same row
  • Updates the moment you log a payment

The year

Spot the tenant before they become a problem.

Twelve months, one row per tenant. Spot a pattern before it becomes arrears — the slow creeper, the two-months-late, the tenant who always pays on the 29th.

  • Colour-coded months — paid, pending, overdue
  • Hover any cell for the underlying payment
  • Export any period to CSV in one click (Pro)

Send the awkward email without writing it.

Professional reminder emails in a single tap — drafted, branded, logged. No tone-checking, no copy-pasting last month’s note, no wondering what you said last time.

  • A branded, deliverable reminder email
  • A record of every reminder beside the tenant

The fix

Every repair, from reported to done.

Track maintenance through a clear workflow — reported, scheduled, in progress, done. Assign a rated contractor, log the cost, attach photos. The job history stays on the property even after a tenant moves on.

  • Status workflow — reported → scheduled → in progress → done
  • Assign a star-rated contractor and log the final cost
  • Photo evidence and full history on every property
