How to engage RG INSYS

One page: choose an engagement model, ballpark the cost, and see the process, onboarding, and SLAs you can hold us to.

1. Choose an engagement model

These four cover 95% of engagements: pick by scope clarity, budget predictability, and duration.

Model 1

Fixed-price project

Best when the scope is clear and you need budget certainty.

Fixed Statement of Work with milestones, deliverables, and a single price. Change requests costed separately.

  • Typical project: MVP, redesign, migration, focused feature build
  • Milestones billed on acceptance, not on time
  • Includes one round of revisions per milestone
From $5,000 · typical 4–16 week project
Model 2

Monthly retainer

Best for ongoing iterative work where scope shifts week to week.

Fixed monthly fee, guaranteed senior engineering hours. You re-prioritise weekly; cancel with one month notice.

  • Typical use: feature factory, AI integration, continuous modernisation
  • Weekly demo + written status report
  • Roll over up to 20% of unused hours one month
From $3,000 / month · minimum 3 months
Model 3

Dedicated developer

Best when you want a named engineer embedded in your team.

One full-time engineer (160 hours/month) in your standups, Slack, and GitHub. AI tooling (Claude, Cursor, Copilot) provided by us.

  • 2-week free trial; pay nothing if not a fit, or we replace at no cost
  • Backup engineer covers planned and sick leave
  • Replace anyone with 2 weeks notice, no replacement fee
From $2,400 / month · minimum 3 months
Model 4

Dedicated team / pod

Best for full product builds, migrations, or multi-quarter programmes.

Cross-functional pod: 2–8 engineers + tech lead across frontend, backend, DevOps, and QA. Scale up or down monthly, no penalty.

  • Tech lead included free above 3 engineers
  • Two-week sprint cadence with demos
  • Code reviews, CI/CD, and observability included
From $6,000 / month · minimum 3 months

Not sure? Try the build vs buy calculator or in-house vs offshore TCO calculator, or book a 30-minute call and we will recommend one.

2. Ballpark the cost

Realistic ballparks for common engagements; these are floors, not ceilings, and complex regulated work runs higher.

EngagementTypical cost (USD)Typical duration
Technical audit / discovery sprint$4,000 – $8,0002 weeks
AI proof of concept$8,000 – $15,0003–6 weeks
MVP build (mobile or web)$25,000 – $60,0008–14 weeks
Legacy migration (PHP → Node, .NET → modern)$40,000 – $120,00012–24 weeks
VoIP / contact centre build$30,000 – $90,00010–20 weeks
Dedicated developer (per month)$2,400 – $5,800Ongoing
Dedicated pod of 4 (per month)$10,000 – $18,000Ongoing

For a personalised ballpark use the project cost calculator (browser-only, no email needed) or the full pricing page. Written estimate within 48 business hours of a brief.

3. Our delivery process

Six phases, whatever the model; the full process page adds a sample 8-week plan and RACI matrix.

  1. Brief and free scoping call (30 min)

    You share the problem, constraints, and timeline; we ask hard questions. Output: whether we are a fit.

  2. Written estimate within 48 hours

    Scope, milestones, fixed price or rate, assumptions, exclusions, and a single-page risk register. Shop it against other vendors.

  3. Discovery sprint (optional, 1–2 weeks)

    Paid technical deep-dive: API spike, data model draft, UX wireframes, security review. De-risks the estimate.

  4. Build sprints (2-week cadence)

    Sprint planning, daily standups, demo on Thursdays. Working software in your environment from week one.

  5. Stabilisation and handover

    Bug-fix-only sprint after feature freeze, then documentation, runbooks, on-call training, and knowledge transfer.

  6. Warranty and incident support

    30 days of free bug-fix warranty post-handover. Optional managed L1–L3 support thereafter.

Every sprint follows our public engineering methodology: trunk-based development, AI-assisted PR review, 80%+ test coverage, full CI/CD with security scans, and a strict Definition of Done.

4. Contracts, NDA, and IP

A standard bundle of four agreements; your templates accepted if reasonable:

  • NDA; mutual by default, signed before any commercial-in-confidence disclosure. Your template is fine.
  • Master Services Agreement (MSA); governs all work. Our sample MSA shows the standard clauses (IP assignment, liability cap, payment terms, governing law).
  • Statement of Work (SOW); per-project schedule: scope, deliverables, milestones, fees, change-request mechanism.
  • Data Processing Addendum (DPA); required if we process personal data. See our GDPR-aligned DPA template.

All IP and code is assigned to you on payment; we retain nothing after handover beyond what support requires, in your repos and accounts. Sub-processors are listed on the security page and you can object to any.

5. Onboarding; week 1

Signed SOW to first production-quality commit: usually 5 to 10 working days.

  • Day 1: Engineer in your Slack, Jira, GitHub. Repo access and dev environment confirmed; backup engineer briefed.
  • Day 2: Architecture walkthrough with your tech lead, local environment running end-to-end, first trivial PR as a repo-access sanity-check.
  • Day 3–5: First substantive ticket, pair-programming for codebase context, CI/CD and test pipelines verified.
  • Day 6–10: First feature-level PR, stakeholder demo on the second-week Thursday, retrospective and feedback.

6. SLAs and response times

The SLA page has the full targets. Highlights:

  • Sales response: within 4 business hours, UK / EU / US East business hours.
  • Written estimate: within 48 business hours of a complete brief.
  • P1 production incident (managed support contracts): acknowledged within 30 minutes, engineer engaged within 60 minutes, root-cause communication within 4 hours.
  • P2 incident: acknowledged within 2 business hours, engineer engaged within 4 business hours.
  • Standard delivery SLAs: sprint demos every 2 weeks, written status update every Friday, escalation path published in the SOW.

7. Exit and handover

End any engagement with one month notice (or per the SOW for fixed-price work). Exit is included, not extra:

  • All code, infrastructure, and documentation is already in your accounts and repos.
  • 2-week handover sprint with your incoming team: pair sessions, runbooks, written knowledge-transfer document.
  • Final invoice covers only work delivered to the exit date. No exit penalty.
  • 30-day post-exit warranty covers regressions on delivered code at no charge.

Unhappy? Escalate to your account director; we would rather fix it than lose you. If you still leave, we help you leave well.
