KEEN SYSTEMSGet a QuoteBuild a custom web application with Keen Systems in Sri Lanka: customer portals, business dashboards and connected workflows designed around the way your team operates.
Kaduwela, Sri Lanka · Local and remote delivery
A custom web application lets people complete work through a browser: submit requests, approve changes, manage records or review operations. We connect those screens to the business rules, permissions, data and integrations required for a dependable workflow.
Tell us what you are planningGive customers, suppliers or agents a clear place to submit information, follow progress and manage permitted records.
Bring approvals, operational records and reporting into a shared application with explicit rules and ownership.
Connect existing systems or replace fragile manual steps in reviewable stages, preserving useful data and operational continuity.

View the projectScope, responsibilities and acceptance checks are agreed together. You review useful progress as the project takes shape.
Clarify the business outcome, users, current systems, constraints, risks, ownership and evidence required to call the work successful.
Turn the discovery findings into boundaries, modules, interfaces, milestones, quality expectations and an implementation path.
Build and validate working increments so stakeholders can examine behaviour, data, usability and operational readiness before release.
Prepare environments, monitoring, documentation, access, rollback expectations and support ownership before production use begins.
Use production evidence, user feedback and service indicators to prioritise improvements without losing architectural discipline.
A business website mainly presents information and helps visitors enquire. A web application lets users complete tasks with accounts, business rules and stored data, such as approving a request or managing an order. A project can combine both behind one coherent experience.
The distinction affects scope: interactive business workflows require rules and data design beyond page presentation.
List who uses the system, the actions they take and which existing tools or records they depend on.
Design complete journeys with input validation, permission checks and clear success or failure states.
Treating a working dashboard screen as a complete application can leave security, reporting and exception handling unfinished.
Validate the full journey with representative users and records, including the steps taken after an error.
Protection starts with agreed access rules, secure authentication, server-side permission checks and validation. Data handling, logging, backups and recovery must fit the information being processed. Security requirements are reviewed for the specific application and hosting environment.
A hidden button does not provide access control; the server must check whether the action is allowed.
Define staff roles, record ownership, sensitive fields, retention and which actions need an audit trail.
Apply the access rules to reads and writes, protect credentials and test cross-role access before release.
Shared accounts, excessive access and sensitive data in diagnostic logs can undermine otherwise sound application design.
Check authorised and denied scenarios, restore readiness and the traceability of important changes.
Yes, where the connected systems provide suitable interfaces and authorised access. A shared API can support web and mobile clients; ERP connections need ownership and reconciliation rules; AI features need approved data, evaluation and an appropriate human handover.
An integration is a business handoff as well as a technical connection.
Confirm vendor API availability, rate limits, record identifiers, data permissions and responsibility for failed requests.
Use validated contracts, duplicate protection, retry handling and observable outcomes. Introduce AI against a narrow, reviewable use case.
Unavailable APIs, conflicting records or unreviewed AI output can create misleading statuses and operational mistakes.
Exercise successful, repeated and failed requests and confirm that staff can diagnose and resolve exceptions.
We select the stack around content, integrations, security, maintainability and the people who will own the system.
Interfaces are designed for the tasks, device constraints and access needs of each user role.
Choose the backend and data model for the transaction rules, integrations, reporting and long-term support requirements.
Plan environment ownership, deployment checks, backups and restore responsibilities alongside the application.
Share your requirements for a proposal that makes scope, cost, timing and ongoing ownership clear.
Consider a custom application when important workflows, permissions, integrations or reporting needs are poorly served by existing products. Discovery should compare configuration, integration and custom development so the investment matches the problem.
Pricing depends on workflow complexity, user roles, data migration, integrations, quality requirements and support scope. Keen Systems reviews those requirements before proposing milestones and a quotation. Hosting, external services and future enhancements are identified separately.
Yes. A first release can focus on one complete, useful workflow with the permissions, data handling and operational checks it needs. Later modules can be prioritised from user feedback without requiring every planned feature at launch.
A responsive web app can work in supported mobile browsers. Offline work, background activity, device hardware and app-store distribution require explicit requirements and may justify a dedicated mobile application.
Potentially, yes. We first review the vendor interfaces, access rights, record ownership and required sync direction. Integration scope includes duplicate handling, failure recovery and reconciliation rather than just sending data between screens.
The proposal should define source-code and deployment access, hosting ownership, documentation, maintenance responsibilities and support expectations. Keen Systems can scope ongoing support, and handover requirements should be agreed before development begins.
Yes, a Keen AI feature can be scoped around an approved knowledge base, enquiry assistance or a staff workflow. We agree what it can access, when a person must review an action and how answers and failures will be evaluated before release.
