Engineering Excellence

Modern stacks, clean architecture, and proven delivery practices on every build.

Modern Tech Stack

React, Next.js, Node.js, Laravel, Python, Go — chosen to fit your problem, not our preference.

Cloud-Native Architecture

AWS, GCP, Azure deployments with auto-scaling, observability, and infrastructure as code.

Security First

OWASP best practices, SOC2-ready architecture, encryption at rest and in transit, RBAC.

CI/CD & DevOps

Automated testing, staging environments, and zero-downtime deployments out of the box.

Robust Data Layer

PostgreSQL, MongoDB, Redis — designed for performance, integrity, and easy migrations.

AI-Augmented Builds

We blend AI tooling into our process to ship faster without sacrificing code quality.

What We Build

From greenfield products to modernizing legacy systems.

B2B SaaS Platforms

12wk
Avg MVP Timeline

Multi-tenant SaaS with billing, RBAC, analytics, and integrations — production-ready in months.

Internal Tools & Admin Panels

60%
Ops Time Saved

Replace spreadsheets and manual workflows with custom dashboards your team actually wants to use.

API & Integration Platforms

200+
Integrations Built

Connect disparate systems with reliable APIs, webhooks, and ETL pipelines built to scale.

Legacy Modernization

5x
Performance Gains

Migrate aging PHP, .NET, or monoliths to modern, maintainable, cloud-native architectures.

Common Challenges

Problems We Help Buyers Solve

Spreadsheet workflows at scale

Operations outgrow Excel and email chains; errors compound when multiple teams touch the same data.

Off-the-shelf doesn't fit

SaaS tools cover 80% of the workflow but the remaining 20% is where your margin lives.

Previous vendor left debt

Inherited codebases are fragile, undocumented, and scary to extend without a senior audit first.

Integration chaos

Payment, CRM, ERP, and legacy systems need one coherent backend — not another silo.

Buyer Guide & Decision Framework

Custom Software Development: Scope, Pricing & Buyer Guide

At-a-glance scope, pricing tiers, delivery timelines, engineering tradeoffs, and decision criteria for technical founders and product leaders.

What is Custom Software Development?

Custom software development covers SaaS platforms, MVPs, admin portals, APIs, and mobile apps — built with Laravel, React, Node.js, or Flutter depending on workflow complexity and team skills.

How much does Custom Software Development cost?

GreeLogix pricing tiers: Architecture & Legacy Code Audit: $2,500 – $6,500 — 1–2 weeks. In-depth code quality, security vulnerability, database performance, and technical debt evaluation. Custom SaaS / Operations Portal Build: $18,000 – $55,000 — 6–14 weeks (Most Popular). End-to-end custom SaaS, customer portal, or internal operations system built to your exact workflows. Dedicated Engineering Pod: $6,500 – $15,000 / mo — Ongoing. Embedded senior full-stack engineers, QA, and tech lead aligned with your product roadmap and sprint cadence.

Key Cost Factors

  • ·Feature count and permission complexity
  • ·Design fidelity (wireframes vs full UI system)
  • ·Integrations (payments, CRM, legacy ERP)
  • ·Mobile apps add parallel API and store submission work

How long does delivery take?

MVPs: 4–8 weeks. Mid-size SaaS modules: 8–16 weeks. Enterprise portals: phased delivery over quarters. Phases: Discovery & architecture (1–2 weeks); Design & prototype (1–2 weeks); Build sprints (4–12+ weeks); Launch & handover (1 week).

Delivery Phases

  1. 1.Discovery: workflows, roles, integrations, and milestone definition
  2. 2.Architecture and data model before feature sprints
  3. 3.Weekly demos on staging with automated tests on critical paths
  4. 4.Production launch with runbooks and optional retainer

Who is it for?

  • ·Founders validating a product idea with paying users, not slides alone
  • ·Businesses outgrowing spreadsheets and email-based operations
  • ·Teams inheriting fragile codebases from previous vendors
  • ·Companies needing one backend for web admin, customer portal, and mobile

When NOT to use this service

  • ·You need a generic website with no custom business logic
  • ·You cannot allocate a product owner for weekly decisions
  • ·You expect enterprise features at prototype budget

Pros / Benefits

  • +Software shaped to your exact workflow and pricing model
  • +Own the codebase and hosting — no per-seat vendor lock-in
  • +API-first builds let web and mobile share one backend

Risks to Plan For

  • −Scope creep turning an MVP into a 6-month build
  • −Skipping QA on admin permissions and payment edge cases
  • −Choosing a stack your next hire cannot maintain

How Does Custom Software Development Compare to Alternatives?

When Custom Software Beats Off-the-Shelf SaaS

Custom software development makes sense when your margin, compliance, or workflow logic is the product — not something a generic tool can approximate with configuration. Teams come to GreeLogix when they've outgrown spreadsheets, when two SaaS subscriptions still don't connect the handoff between sales and operations, or when investors expect a defensible technical moat rather than a no-code prototype.

We start by mapping the business rules that actually matter: permissions, approvals, pricing exceptions, and the edge cases your ops team handles manually today. That clarity drives architecture — API-first backends, admin panels your staff will use daily, and integrations that keep finance, support, and product aligned.

How We Deliver Without the Agency Black Box

Every engagement runs in weekly sprints with demos you can click through. You talk to the engineers building the system, not a rotating account manager. We document as we go, hand over full source ownership, and offer post-launch support when you want a team that already knows the codebase.

If you're comparing vendors, ask whether they'll show you a similar project, who attends your calls, and what happens when scope changes mid-sprint. Our answers are concrete because we've rescued failed 70-engineer engagements and shipped what others couldn't.

  • Fixed milestones or dedicated team extension
  • Laravel, Node.js, React, Flutter
  • QA and code audit before major launches
  • Optional AI automation on top of your product

Frequently Asked Questions

Answers to the buyer questions we hear most before a project starts.

What tech stack does GreeLogix use for custom software?

We use React, Next.js, Node.js, Laravel, Python, and Go on the backend, with PostgreSQL, MongoDB, and Redis for data. Cloud deployments on AWS, GCP, and Azure.

Do you offer post-launch support and maintenance?

Yes. We offer ongoing maintenance retainers covering bug fixes, security updates, performance monitoring, and feature additions after launch.

Can you take over an existing codebase?

Yes. We often start with a code review and technical audit, then propose a stabilization roadmap before new feature work.

How long does a custom software project take?

MVPs and focused modules often ship in 8–16 weeks. Larger platforms are phased — first milestone usually within 4–6 weeks of kickoff.
