Which architecture should custom software use?
We define the architecture around your existing information system, volumes, integration, security, and operational constraints, as well as how your teams will need to maintain the software over time. We regularly work with modern Cloud environments, on-premise information systems, legacy applications, and third-party APIs that are not always well documented.
We support the structural choices: backend and frontend technologies, PostgreSQL, MySQL, or NoSQL according to the nature of the data, a modular monolith or separated services, asynchronous processing, hosting, redundancy, and information-system integration. We favour an architecture that fits your constraints, internal skills, and planned software evolution.
How do we connect software to your information system?
We connect software to ERP, CRM, document platforms, accounting systems, payments, e-signature, identity providers, and business applications through APIs, webhooks, structured files, or the exchange mechanism that best fits the existing environment. Each data set keeps a clearly identified source of truth.
For important workflows, we define identifiers, transformations, retries, logs, synchronization frequency, and idempotency rules. Queues and asynchronous processing can also absorb longer exchanges without blocking the main application.
How do we secure access and data?
We can implement SSO, MFA, and role-based permissions through Microsoft Entra ID, Okta, Google Workspace, or an identity layer suited to the project. Server-side authorization separates viewing, editing, approval, administration, and access to sensitive data.
The security setup can include TLS, encryption of sensitive data, secret management, WAF, firewalls, VPN access, environment separation, audit logs, and backups. Its depth follows the sensitivity of the data and actions available in the software.
How do we prepare production deployment?
We integrate production readiness into the project from development onward, with representative staging environments, validation with your teams, and a reproducible deployment pipeline. Depending on your organisation, we can work with your internal teams or managed-services provider, or take direct responsibility for preparing operations and production procedures.
This continuity relies on our **DevOps expertise**: deployment automation, monitoring, backups, rollback, and environment management. We work with Docker to standardise execution, Terraform when infrastructure needs to be versioned, and Sentry and Grafana to track errors, performance, and operational signals after go-live.
How do we manage software quality?
We adapt testing to the project’s risks: unit tests for business rules, integration tests for system exchanges, and end-to-end tests for critical user journeys. Code review, automated checks, and staging environments support validation before production.
Database migrations are versioned, dependencies are tracked, and important interfaces are documented. This discipline makes future changes, diagnostics, and software handover to another team easier as your organisation evolves.
Standard software or custom development?
Standard software is faster to deploy when your processes already fit its model: you benefit from a vendor, proven capabilities, and a more predictable initial investment. In return, you must accept its objects, workflows, and integrations; gaps may require configuration, workarounds, or additional tools.
Custom development becomes relevant when your business rules, data, or interfaces differentiate your operations and an existing product imposes too many compromises. You gain a solution adapted to your users, with a scope to define and a long-term investment to manage. We can also keep SAP, Salesforce, Sage, Cegid, Odoo, or another core system and develop only the missing business layer around it.
How do we take over existing software?
We start with repositories, environments, Cloud accounts, databases, DNS, certificates, secrets, pipelines, backups, and available documentation. Code and architecture review then identify stable areas, sensitive dependencies, and the first priorities.
The takeover can lead to stabilization, targeted modernization, infrastructure migration, or progressive evolution. The same work helps recover a reproducible deployment chain and readable operations before development accelerates.
How do we organize ongoing maintenance?
Ongoing application support can cover fixes, dependencies, security, monitoring, performance, and smaller evolutions. Incidents, maintenance work, and new development remain clearly separated so priorities and budgets stay readable.
Support can also include library updates, certificates, backups, error review, Cloud optimization, and preparation of new releases.
What drives custom software cost?
Budget is primarily driven by business workflows, user roles, business rules, integrations, data migration, and security requirements. Payments, documents, e-signatures, SSO, advanced reporting, real-time processing, search, offline behaviour, and high availability each add a defined technical scope.
Timeline is also influenced by API availability, existing data quality, business approvals, and the number of systems involved. Scoping turns these parameters into explicit assumptions before estimating.
