The question is simple:
“So, how much does it actually cost to work with DevVina?”
The honest answer is: it depends entirely on how you want to work with us.
Procurement teams often assume that a single outsourcing model can work for every budget and every software development roadmap.
That assumption is exactly what causes most client–vendor relationships to go off track.
Let me walk you through the engagement models we offer, what each one is best suited for, and the trade-offs you should consider before signing a contract.
Project-Based Engagement
This is the model closest to a fixed-scope contract.
You define the requirements, we provide a price and timeline, and then we deliver according to both.
This model works well when the expected output is clearly defined: a migration project, a specific module, a compliance requirement, or a legacy system rebuild.
For a CFO, the biggest benefit is predictability—and that is exactly what this model is designed to provide.
You know the number before the work begins, and you can build your budget around it.
However, the trade-off is real.
Changes in requirements will create additional costs, and scope creep is the enemy of fixed pricing.
If requirements change during development, expect a change order.
That doesn’t mean we’re trying to make things difficult for you. It’s the only way a fixed price can continue to reflect reality.
If you have a stable specification and clear acceptance criteria, this is the most cost-effective model for buying certainty.
Dedicated Team
This is the model most of our clients move to after successfully completing their first project with us.
You’re paying for a team, rather than a specific deliverable.
We provide engineers, QA, and a lead for your project, while you decide what they should prioritize each week.
Your Product Manager owns the roadmap; our team executes it.
From a CFO’s perspective, the budgeting difference is subtle but important.
You’re no longer buying a fixed outcome.
You’re buying delivery capacity, which means the cost becomes an ongoing budget rather than a one-time project expense.
That changes the way you forecast your budget.
In return, you get flexibility: priorities can change, the team can scale up or down with notice, and you don’t have to renegotiate the contract every time the roadmap changes.
The trade-off is this:
You get the level of effectiveness that matches how well you manage the team.
A dedicated team only works when it is properly directed.
If your internal team doesn’t have enough time to manage the partnership, this model won’t reach its full potential.
It works best for clients who are ready to play an active role in leading and sponsoring the project.
Time & Materials With a Cap
This model sits somewhere between the two above and often comes as a surprise to procurement teams.
We estimate the workload, track hours transparently, and agree on a cap that the total cost will not exceed without a written change order.
You get the flexibility of an open engagement model, while still having a guardrail around the total budget.
This works well when the overall scope is relatively clear, but the details are still uncertain.
Think of a platform where you know what end state you want to achieve, but you don’t yet know exactly what every screen along the way will look like.
You avoid the rigidity of fixed-price development without leaving the budget completely open like a pure Time & Materials model.
The CFO’s financial risk is capped—and that’s often exactly what the board wants to hear.
The trade-off is that you need to maintain a regular review cadence.
This model only works if you commit to frequent checkpoints, because a budget cap only truly protects you when both sides can see how quickly the budget is being consumed.
Skip the reviews, and the cap becomes little more than a formality.
Managed Capacity or Staff Augmentation
Some clients don’t need a complete product team.
They just need two senior engineers to join an existing squad, or an additional QA engineer during the release preparation phase.
Staff augmentation fills a specific gap in your team without requiring you to hire full-time employees.
You retain management control, while we provide the specialized expertise.
From a procurement perspective, this is the lowest-commitment starting point.
It is also the model where differences in quality between vendors become visible the fastest, because you’re trusting an individual’s judgment inside your own codebase.
The trade-off is that you take on more of the integration risk.
A contractor who doesn’t integrate well with your team’s culture can cost you far more in collaboration friction than their hourly rate would suggest.
So, What Does This Mean for Your Decision?
There is no single model that is right for everyone.
And any vendor who tells you otherwise is selling what is convenient for them, not what will produce the best outcome for you.
Choose the model based on the maturity of your specification.
If the requirements are fully defined, choose fixed price and stay disciplined about the scope.
If the roadmap is still changing and you have enough internal capacity to direct it, a dedicated team will give you more value for the same budget.
If you’re uncertain, start with a small project-based engagement and let real-world data inform the decision.
Your conversation with procurement shouldn’t start with:
“What is your rate per engineer?”
It should start with:
“What are we actually trying to control—cost or flexibility?”
Answer that question honestly, and the right engagement model will usually become obvious.
There’s one more thing worth saying directly: every engagement model we offer comes with a shared type of cost that vendors rarely include in their quotes—
the time your own team has to spend managing the relationship.
Put that into the budget.
A lower hourly rate that requires your team to constantly provide guidance, supervision, and support isn’t actually cheap.
We’re happy to look at your specific situation with you and recommend an engagement structure that fits, rather than trying to sell you a pre-packaged service.
That conversation is free, and it often clarifies the budget problem much faster than a spreadsheet ever could.
