## What it is

Custom software development is building an application from your requirements
rather than adapting an off-the-shelf product. EnzRossi scopes the work,
assembles a team of engineers, designers and QA from its vetted Latin American
network, delivers against milestones you approve, and transfers the code and IP
to you. This model is sometimes called software outsourcing or project-based
development.

## How we run it

1. Discovery and scoping (1 to 2 weeks): written spec, architecture decisions,
   milestone plan you sign off.
2. Team assembly: engineers chosen for your stack, a tech lead who owns delivery,
   QA from sprint one. You meet the team before kickoff.
3. Sprint-based build: two-week sprints, each ending with a demo on staging.
4. QA and user testing before each milestone.
5. Deployment and handoff: deployed to your infrastructure, documented, 30-day
   warranty.

## Engagement models

| Model | Best for | How you pay | Typical timeline |
|---|---|---|---|
| Fixed scope, milestone billing | A clear brief with acceptance criteria | Fixed price per milestone, paid on acceptance | 8 to 24 weeks |
| Time and materials | A roadmap still moving, discovery-heavy work | Monthly per person | 3 months minimum, then month to month |
| Dedicated product and engineering team | A product area owned end to end | Monthly team rate | 6 months and up |
| Embedded engineers | You have a tech lead and need more hands | Monthly per engineer | Shortlist in days, then month to month |

## Cost

With a LATAM team most projects land between $60,000 and $400,000. Minimum
project size is $15,000. Comparable US agency quotes are typically 40 to 60
percent higher. Discovery produces a fixed number before you commit.

## Who it is for

- Enterprises modernizing legacy systems or running digital transformation programs
- Product companies with a roadmap item their core team cannot take on
- Startups building a first version (see MVP development)
- Teams with technical debt, migrations or major upgrades

## Facts

- Milestone billing: you pay when a milestone is delivered and accepted
- 30-day warranty on every project
- Code, IP, cloud accounts and documentation belong to you from day one
- NDA and IP assignment on every engagement; engineers sign individually
- Enterprise experience: largest engagement runs more than 10 squads
