Why we built it
Rental records should not depend on memory, message threads, and folders.
Many landlords start with one property and a simple spreadsheet. As more tenants, rooms, payments, repairs, agreements, and renewal dates appear, the rental history becomes harder to reconstruct. KitaSewa brings those recurring records into one connected mobile workflow.
Records spread across too many tools
Rental details often live across WhatsApp, Excel, Drive folders, paper agreements, receipt photos, and memory.
Tenancy history is hard to review later
Agreements, payments, repairs, renewal requests, and issue updates need to stay attached to the right tenancy.
Follow-ups are easy to miss
Rent due dates, insurance renewals, repairs, and property tasks need reminders before they become problems.
Sensitive rental details need care
Tenant contact details, ID information, bank details, documents, signatures, and uploaded files need authenticated access and careful handling.
What it helps users do
Turn monthly rental admin into connected records.
KitaSewa keeps the information landlords repeat every month attached to the right rental context.
Manage whole-unit and room rental setups
Create properties, manage rooms, choose whole-unit or room-by-room rental, and keep room records tied to the correct property.
Keep tenant and tenancy records together
Track tenant details, owner-managed tenancies, invited tenant participation, tenancy status, start dates, rent periods, deposits, and due dates.
Generate, upload, store, and sign agreements
Support generated in-app agreements, owner-uploaded PDF agreements, existing tenancies with no file, tenant signature requirements, and agreement documents.
Track rent and related payments
Record rental payments, deposits, other payments, property income, paid amounts, due dates, payment status, and supporting receipts or files.
Record maintenance and issue history
Let owners and tenants report issues, track repairs, update issue status, and keep related photos or documents.
Set reminders for important rental tasks
Link reminders to properties or tenancies, assign them, mark them completed or cancelled, and support recurring schedules.
Keep supporting files and images attached
Upload files and images for properties, rooms, tenancies, histories, reminders, income, expenses, and furniture records.
Maintain property expenses and inventory records
Track property expenses and furniture or inventory items, including claim values, condition status, room assignment, and attachments.
