Engagement models · Six ways to work together

Pick the contract that fits the work, not the other way round.

We don't push a one-shape-fits-all retainer. Whether you need a dedicated long-term team, a fixed-scope sprint, an offshore extension, or boots on the ground — we'll pick the model that matches your scope, budget, and risk profile.

Hire Dedicated Resource Model Model 01

Engagement model #1

Hire Dedicated Resource

Best for

Startups, SMEs, long-term builds

Key benefits

Dedicated team, cost savings, full scalability

A skilled team works exclusively on your project — reporting to you, embedded in your rituals. Ideal for long-term collaboration where flexibility, complete control, and unit-cost efficiency matter most.

How we deliver
Fixed Time & Cost Model Model 02

Engagement model #2

Fixed Time & Cost

Best for

Small-to-medium projects with strict budgets

Key benefits

Fixed budget, on-time delivery, full transparency

Tightly-scoped projects with clearly defined requirements and deadlines. No budget overruns, no scope creep — ideal for short-term, goal-oriented engagements.

How we deliver
Time & Material Model Model 03

Engagement model #3

Time & Material

Best for

Dynamic projects with uncertain scope

Key benefits

Maximum flexibility, agile cadence, only-pay-for-what-you-use

Pay for the time and resources actually used. Suited to evolving products where requirements shift between iterations and the right answer is to adapt rather than amend the contract.

How we deliver
Development Centre Offshore Model 04

Engagement model #4

Offshore Development Centre

Best for

Large-scale, long-term programs

Key benefits

Cost reduction, global talent, extended team

A dedicated ODC functions as an extension of your in-house team — same standards, lower run-rate, faster ramp on specialist roles you can't hire locally.

How we deliver
Hybrid Offshore-Onshore Model Model 05

Engagement model #5

Hybrid Offshore-Onshore

Best for

Mid-to-large enterprises

Key benefits

Optimised costs, 24/7 productivity, QA layer onshore

A strategic blend — offshore production capacity with onshore leadership and close client collaboration. The best of both, without the cultural friction either alone produces.

How we deliver
Onsite Resource Augmentation Model 06

Engagement model #6

Onsite Resource Augmentation

Best for

Enterprise support, urgent hiring needs

Key benefits

Immediate talent, direct collaboration, full scalability

Skilled professionals placed directly into your organisation — working alongside your in-house team to close resource gaps and accelerate delivery without the multi-month hiring loop.

How we deliver

Frequently asked

The questions we hear before every kickoff.

What engagement models does Nexlla offer?

Six models, in order of how often they're chosen:

  • Hire Dedicated Resource — full-time team working only on your project.
  • Fixed Time & Cost — fixed price and timeline.
  • Time & Material — pay for what you use, ideal for evolving scope.
  • Offshore Development Centre — extended team housed offshore.
  • Hybrid Offshore-Onshore — production offshore, leadership onshore.
  • Onsite Resource Augmentation — skilled professionals embedded in your office.
How do I pick the right one?

It comes down to scope and certainty:

  • Long-term build → Hire Dedicated Resource.
  • Fixed budget & timeline → Fixed Time & Cost.
  • Scope uncertain or evolving → Time & Material.
  • Aggressive cost optimisation → Offshore or Hybrid.
  • Immediate team expansion → Onsite Augmentation.

Not sure? Send us the brief — we'll recommend one in our first reply.

What are the benefits of an offshore model?
  • Cost savings — reduced operational and hiring overhead.
  • Access to global talent — specialist roles you can't fill locally.
  • Round-the-clock productivity — time zone overlap accelerates delivery.
  • Scalability — ramp up or down quickly without HR friction.
How does the Time & Material model actually work?
  • You pay only for actual work delivered — no fixed cost ceiling.
  • Scope can shift between sprints without renegotiating the contract.
  • Real-time progress updates and iterative releases keep you in control.
  • Team size flexes up or down based on demand — weekly if needed.
Can we switch models mid-project?

Yes. We've taken clients from Fixed Time & Cost into Dedicated Resource (and back) more times than we can count. The right model for the discovery phase is rarely the right model for the scale phase — we'll suggest a transition when the data says it's time. Reach out and we'll walk you through how that looks.
