Engagement Models for Software Development
One size doesn’t fit all—especially in software development. Yellow offers flexible engagement models tailored to your needs. Whether you’re launching a new startup, scaling a growing business, or tackling a complex enterprise project, we’ve got the right approach to deliver results on your terms.
How to Choose the Right Engagement Model
Selecting the right engagement model for your software development project is crucial for aligning your business goals with budget, timelines, and deliverables. Here are the main criteria you should consider when choosing the right cooperation model:
Project size & complexity
Define the scope of the project.
Budget flexibility
Choose between hourly and fixed-price payment structures.
Level of control desired
Assess how much control you want over the project and your preferred level of involvement.
Long-term needs
Decide if you require ongoing support, scalability, and post-launch maintenance.
Project-Based Model
How it works
A project-based model is a contractual approach where the client and Yellow agree on the scope, timeline, and costs for a specific project upfront. This model is ideal for clients with well-defined project requirements (SRS), limited budgets, and clear outcomes.
Best for
Short-term projects, building an MVP for startups, modernizing a legacy system, developing a standalone application with predefined functionality.
Advantages
Challenges
Outstaffing Model
How it works
You hire external developers or an entire team that works as part of your in-house team. These professionals are employed by Yellow but work exclusively on your project under your direct supervision. You manage their daily tasks and the workflow, while we handle administrative aspects like payroll and legalities.
Best for
Companies needing to scale their in-house team quickly or access specific technical expertise without long-term commitments.
Advantages
Challenges
Dedicated Team Model
How it works
We allocate a full-time team of skilled professionals who work exclusively on your project. The team operates as an extension of your business, fully aligned with your goals and processes.
Best for
Long-term projects requiring ongoing development and collaboration.

Key Differences of Engagement Models
When choosing the right engagement model for your project, it's important to understand the key differences between outstaffing, project-based, and dedicated team models. Outstaffing involves hiring external professionals who work under the client's management, with the outstaffing provider handling administrative tasks. Project-based engagements are focused on delivering specific outcomes within a set timeframe and budget. In contrast, dedicated teams work exclusively on a client’s projects, acting as an extension of the client’s internal team, with a high level of integration and control for an extended period.
| Aspect | Outstaffing | Dedicated Team | Project-based |
|---|---|---|---|
| Management | Client | Shared/Provider | Provider |
| Control | Full | High | Low |
| Flexibility | High | Medium | Low |
| Costs | Pay for resources only | Team + management overhead | Fixed cost |
Pricing Models
Here are the common pricing models used in Yellow for software development projects:
Time and materials based on hourly rate
The client is billed based on the actual number of hours spent by each team member.
Best for: Mid/long-term projects, undefined scope, or ongoing support.
Advantages: Flexibility, transparency in billing.
Challenges: Uncertainty in overall cost, harder to predict total expenses.
Fixed price
A set price is agreed upon for the entire project, regardless of time spent.
Best for: Well-defined projects with a clear scope.
Advantages: Predictable cost, no surprises.
Challenges: Less flexibility for scope changes.
Whether you need a dedicated team, project-based support, or scalable outstaffing, we’ve got a model tailored for your needs.
Testimonials
Here’s what our clients think about us.
The new features have been well received by users. Attentive and flexible, the team excelled at responding to stakeholders in a timely matter. Their technical expertise allows them to propose valuable solutions.
Engaged, supportive, and invested in project success, the team offered constructive criticism, creative guidance, and honest communication. Their user-centered approach resulted in a unique and reliable product that operates well on all systems.
Because of marketing costs, the B2C application fell out of use in favor of a different B2B tool. Yellow was very focused on customer satisfaction, and they participated regularly in standups. They helped solidify features, and they thoroughly explained their process.
We’re impressed with their loyalty and honesty. They were able to stay true to their original quote even though we needed to change and add a few requirements. They’ve done a lot of good work for us on all fronts, but it's amazing to see that they’re able to stick to what they initially promised.
Mainly, I go by client feedback to judge Yellow’s performance, and the clients have been very impressed with their work. The team is exact in what they do, their delivery has been good, and they’re on time and budget.
Their performance was good. I didn’t expect that kind of performance from someone working offsite. I was happy that they completed the project ahead of schedule, so we had some time left to work on additional projects and improvements.
When Yellow is working on a task, they understand how it will impact the product down the line. The team has provided great insight into our processes, making sure we don’t make small mistakes that will impact us in a larger way in the future.
They were very accessible regardless of the time difference as well as communication was good. We had a couple bumps here and there regarding designs that were not originally discussed in our UX/UI designs but they were quick to find solutions as well as any needed changes we requested.
