Kontrak.in is a property and lease contract management platform built for the Indonesian kos and kontrakan rental market. Its goal is to help landlords manage properties, rooms, tenants, bills, contracts, and income reports from a single dashboard. It is more of a vertical SaaS product than a general-purpose CRM or accounting system.
Based on the extracted text, the platform covers a fairly complete set of core modules: adding, editing, and managing properties and rooms; automatically generating monthly invoices for active tenants; sending payment reminders via WhatsApp and Email; generating lease contracts automatically, exporting them as PDFs, and sending them to tenants by Email or WhatsApp. For payment management, it supports manual verification, uploading payment proof, and real-time payment status tracking. On the reporting side, users can view revenue, occupancy rate, and business KPIs, with CSV/Excel export also mentioned.
The page clearly shows “Gratis selamanya” — free forever — and emphasizes that setup can be completed in 5 minutes. However, the pricing section only displays a “loading plan prices” message. The terms state that it offers service plans with different features and limits, that prices may change, that payments are generally non-refundable, and that users may cancel their subscription at any time, with cancellation taking effect at the end of the current billing cycle. Before purchasing, users should therefore visit the pricing page or contact the team to confirm plan limits, billing cycles, and taxes.
On security, Kontrak.in says it uses enterprise-grade encryption and advanced security systems, with a security team responsible for protecting data. The terms state that users retain ownership of uploaded data, while the platform stores and processes that data to provide the service. However, the text does not disclose details about backups, audit logs, permission controls, compliance certifications, or data residency. There is also no visible information about team collaboration, role-based permissions, APIs, developer documentation, or self-hosted deployment. The only third-party integrations clearly mentioned are WhatsApp and Email.
Its strengths are its clear positioning and its fit with how Indonesian landlords commonly communicate via WhatsApp. It covers the full rental management workflow and is well suited to kos/contrakan owners who still rely on Excel, chat histories, and manually collected payment proof. Its limitations are limited pricing transparency, payment automation that appears to be relatively manual, and a lack of API, permission, and compliance details. It is less suitable for companies with complex multi-site operations, multi-role approval workflows, or requirements to integrate with financial systems.
Access from mainland China is unknown. The product is clearly designed around Indonesian laws, language, and rental practices, so payments and local compliance would also need to be evaluated separately. For managing long-term rental apartments or dormitories in China, local housing rental/property management systems may be more appropriate, or teams could build alternative workflows on top of WeCom, DingTalk, Feishu, and low-code platforms.
