FAQ

Software development in New York: FAQs

Practical answers for New York teams assessing custom software scope, delivery models, source-code ownership, integration requirements, security and ongoing support.

How much does software development cost in New York?

Software development cost in New York depends on scope, integrations, security needs and delivery complexity. Financial-services and healthcare projects often need extra security review and testing. We review your requirements before providing an estimate.

How long does a custom software project take?

Custom software timelines depend on scope, integrations, testing needs and approval cycles. Smaller builds may take weeks, while larger platforms usually take several months and often launch in phases.

Which software development engagement models do you offer?

We offer project delivery, dedicated product teams and staged modernization programs. The right model depends on roadmap length, internal capacity, governance and how much delivery ownership you want us to take.

Who owns the source code and intellectual property?

Source-code, licensing and intellectual-property terms are defined in the engagement agreement. Repository access, documentation, deployment guidance and knowledge transfer are planned before handover.

How do you handle security and governance requirements?

We address security and governance from the start of the project. Delivery can include role-based access, audit logging, secure APIs, encryption, testing and controlled releases. Controls can be aligned with NY SHIELD Act requirements where applicable.

What support do you provide after the product goes live?

After launch, we continue to support the product through maintenance, updates, and improvements. Many clients work with us long term to add new features or adjust the software as their business changes. This ongoing support helps ensure the product remains stable and useful over time.

How do we get started with SDLC Corp?

You can start with a simple conversation about your idea or challenge. You do not need a full set of requirements. We will ask the right questions, review what you already have if applicable, and suggest next steps so you can decide how to move forward with confidence.

What software development services do you offer in New York?

As a software development company in New York, we build custom web, mobile and enterprise applications for financial services, healthcare, media and real estate teams. We also connect existing systems and support software after launch.

Can you take over an existing software product or codebase?

Yes. We can assess an inherited codebase, identify reliability and security issues, stabilize delivery and define what should be retained, refactored, modernized or replaced.
