What are the most requested services of custom software development firms?
The most requested services from custom software development firms are almost entirely AI-based products, delivered primarily through web application development, mobile development, AI agent development, and legacy system refactoring. UX/UI design, cloud infrastructure, DevOps, and QA automation are typically not sold as standalone services; instead, they are embedded within each of these project types.
As reported by Diffco, year-over-year trends show a prevailing shift: AI agent development has grown from a niche request into a significant share of overall volume, while demand for legacy system refactoring continues to rise as clients seek to prepare their existing systems to support AI capabilities.

How much does a software development company charge for its services?
The cost of software development services depends on the tech stack, core functions and features, compliance and integration requirements, project complexity, and engagement model.
Developers in North America will charge more than those in Europe or Asia, so you should budget for $120-$200/hr for American developers and $25-$150/hr for a software developer from Asia or Europe.
Custom software development cost estimates based on project complexity:
Project type
Cost
Simple App / MVP (minimal features)
$50,000-$150,000
Medium Complexity (CRM, marketplace sites)
$150,000-$500,000
Large Enterprise Software
$500,000-$2,000,000+
Examples (ERP/Complex Platforms)
$200,000 and up
How do I determine if a global company is the right size for my project?
To determine if a global software development agency is the right size for your project, match project complexity and scale to company capacity.
Choose a large/global agency with 1000+ staff, if your project:
Is complex or enterprise-grade, includes multiple software solutions, integrations, and compliance
Needs 24/7 support, multi-time-zone delivery, or long-term maintenance
Large software development companies reduce delivery risk for complex programs but typically charge higher rates and use more structured processes.
Choose a small or mid-size agency with 10-200 staff if your project:
Is an MVP or mid-scale build
Requires speed, flexibility, and direct access to senior talent
Has a tighter budget and well-defined scope
Who owns the Intellectual Property (IP) and source code at the end of the project?
In most software development projects, the client owns the Intellectual Property (IP) and source code upon completion of the engagement, unless the contract explicitly states otherwise. Standard practice dictates that the ownership of the source code, documentation, design elements, and custom deliverables belongs to the client upon full payment. Contracts typically use "work made for hire" or an IP assignment clause to formalize this.
Third-party or open-source components, however, are not owned by the client. Instead, they are used under their respective licenses. Some agencies retain ownership of pre-existing frameworks or reusable tools and grant the client a license to use them. You should also know that IP ownership is not automatic. To avoid disputes, ensure the contract clearly states full IP and source-code ownership transfers to you upon payment, with no usage limitations.
What tools and frameworks do software developers use?
They use various tools and frameworks, depending on the type of digital product they’re building. But the most common include:
How many hours of integration work do software development projects typically entail?
Software development projects require between 20 and 500 hours of integration work per system, depending on complexity.
Integration type
Typical effort
Simple services (email, SMS, analytics, payments)
20 to 80 hours each
CRM and auth/SSO
40 to 120 hours each
ERP, healthcare (HL7/FHIR), banking/KYC
150 to 500 hours each
As per Diffco, the number of integrations also scales with project size: small builds typically involve 2–4 integrations, mid-sized builds 5–10, and large enterprise platforms 10–25 or more. The software development company also discloses that integrations are inventoried and priced individually rather than folded into a single project total, allowing clients to phase the more costly integrations as needed.
