A web application should simplify an operation, structure data, or enable a new service without creating a technical layer that becomes difficult to operate. Koragence designs custom applications around your users, business rules, and information system, then supports production launch and future evolution.
Koragence designs business web applications, client portals, extranets, back offices, and SaaS platforms around your actual needs. We cover scoping, UX/UI, front-end and back-end development, accounts and roles, workflows, APIs, CRM and ERP integrations, production launch, and maintenance. You can start from an idea, a specification, or an existing tool to take over: we turn the need into a clear, reliable, and genuinely usable application.
Tell us about your needs, current tools, and constraints. We will help define the solution, integrations, and right scope before development starts.
We start by mapping users, responsibilities, business data, and the steps that move work forward: case creation, approval, payment, document generation, notification, export, or transfer to another system. This turns your operating rules into workflows, roles, permissions, and automation that both business teams and IT can review clearly.
Your project is our priority. We work with transparency and close collaboration, documenting every step to preserve your autonomy and avoid dependency.
We structure the scope around the capabilities the application requires: authentication, company accounts, role management, forms, statuses, comments, documents, signatures, payments, notifications, dashboards, and administration. Data migration, third-party systems, and business rules are identified early so the project starts with a clear and estimable scope.
We connect the application to your CRM, ERP, document management platform, accounting software, payment services, e-signature tools, and business APIs. Each integration defines the source of truth, trigger, direction of exchange, and error-handling strategy. Webhooks, asynchronous processing, queues, automated retries, and integration logs can support larger or more critical workflows.
We can implement SSO, MFA, granular permissions, and audit logging for sensitive actions, using Microsoft Entra ID, Google Workspace, Okta, or a dedicated identity layer depending on your environment. The scope can also include encryption, secret management, WAF rules, Cloudflare protection, firewalls, private networks, VPN access, environment separation, and restricted administration access.
We can structure development, staging, pre-production, and production environments, automate releases through CI/CD, prepare rollback procedures, and monitor errors, performance, and availability. Centralized logs, Sentry, Grafana, alerting, backups, and restoration testing give technical teams the information they need to diagnose incidents and restore normal service quickly.
We prepare maintenance from the architecture stage through controlled dependencies, versioned database migrations, documented APIs, tests around critical workflows, and reproducible deployments. Ongoing support can then cover fixes, upgrades, monitoring, performance improvements, and new functionality, with a clear distinction between operational maintenance and larger development work.
Standard software provides a faster starting point, an established feature set, and a more predictable initial investment for common business processes. Custom development gives you full control over business rules, roles, data structures, interfaces, and integrations when those elements are specific to your organisation.
We can also combine both approaches by keeping your existing CRM, ERP, or document platform and building only the custom business layer that coordinates your specific data, approvals, and workflows.
We work through business and technical workshops, specifications, architecture, interface design where required, development, integrations, testing, acceptance, and production release. Your client workspace centralizes the roadmap, decisions, documentation, and feedback. Development, architecture, UX, DevOps, cybersecurity, and data expertise are then brought in according to the project’s requirements.
Budget is primarily driven by user roles, business rules, integrations, data migration, and security requirements. Complex workflows, document generation, e-signatures, payments, SSO, advanced reporting, detailed audit history, and high-availability requirements can expand the scope. The quality of existing APIs, source data, and documented business rules also directly affects scoping and integration effort.
We build a readable foundation for your teams: clear responsibilities, a coherent data model, controlled dependencies, reproducible deployments, and useful documentation. This organization makes future changes, maintenance, and product handover easier over time.
Koragence brings together profiles able to connect scoping, user experience, development, integrations, and operations around one product.
Schools represented in the Koragence network include EPITA, EPITECH, ESSEC Business School, HEC Paris, École Polytechnique, and CentraleSupélec.
Yes. We can start from existing specifications and review journeys, dependencies, data, and remaining ambiguities before development begins. The goal is to preserve what is already clear and resolve the decisions that can genuinely affect scope or architecture.
