Custom web application and software development for businesses
A custom web application supports a specific process that off-the-shelf tools do not cover well. It can centralize data, automate repetitive work, connect multiple systems, and provide an interface tailored to employees, customers, or partners. Daillac handles the project end to end, from discovery through launch and ongoing improvements. Depending on the need, the solution may be a portal, SaaS product, dashboard, CRM, ERP, or specialized business tool.
// decision.criteria
When does custom development make sense?
Existing software is often the best choice when it meets the need without heavy customization. Custom development becomes relevant when the workflow, integrations, or expected experience create a meaningful business advantage.
criterion_01
A company-specific process
The required steps, business rules, or approvals do not fit cleanly into a generic tool.
criterion_02
Disconnected data and systems
The solution must connect APIs, a database, CRM, ERP, or partner services.
criterion_03
Different users and access levels
Employees, customers, or partners need distinct workflows, permissions, and dashboards.
criterion_04
A product designed to evolve
The scope must accommodate new capabilities, markets, and a growing number of users.

// scope.and.budget
What affects the cost of custom software?
The budget depends on functional scope and actual complexity, not just the number of screens. Initial discovery separates the MVP needed for launch from capabilities that can be delivered in later phases.
- Number of workflows, user roles, permissions, and business rules.
- UX design, screen count, and the level of interface customization.
- Data migration and integrations with APIs, CRM, ERP, or external services.
- Authentication, security, audit logs, and compliance requirements.
- Real-time features, artificial intelligence, and multilingual support.
- Maintenance, support, hosting, and the pace of improvements after launch.

Custom development frequently asked questions
What is the difference between a website and a web application?
A website mainly presents information and supports acquisition. A web application lets users complete tasks, manage data, access secure spaces, or carry out business processes.
What types of applications can Daillac build?
Daillac can design customer portals, business tools, SaaS platforms, dashboards, custom CRM or ERP systems, reservation systems, automation, and products connected to external services.
How much does a custom web application cost?
Cost varies with capabilities, user roles, design, data, integrations, security, and operating requirements. A discovery phase establishes a scope that can be estimated and separates the MVP from later phases.
How long does it take to develop an application?
The timeline depends on project scope and dependencies. After discovery, Daillac proposes a realistic delivery sequence, often organized around an MVP followed by prioritized iterations.
Can you take over an existing application?
Yes, after reviewing the code, architecture, data, hosting, security, and maintenance constraints. This assessment determines whether stabilization, progressive modernization, or replacement is appropriate.
Can you integrate a CRM, ERP, database, or API?
Yes. Integrations can synchronize data, trigger automation, and reduce duplicate entry. Feasibility depends on the documentation, access, and technical limitations of the systems involved.
Who owns the code and data?
Access, deliverables, hosting, ownership, and reversibility terms are clarified in the agreement before development begins so that responsibilities are explicit.
Do you serve businesses in Montreal?
Yes. Daillac is based in Saint-Jerome and serves businesses across Greater Montreal, including Montreal, Laval, the North Shore, and the Laurentians.
