Custom Build Services

From first workshop to production maintenance

Every phase of a custom CRM/ERP project, from technical discovery to post-deployment support. One point of contact, proven methodology.

7 phases, from zero to production

Each phase can be ordered separately depending on your situation — you may already have a defined architecture or a frontend team.

01

Discovery & Architecture

2–4 weeks

We start from your business needs and design the technical architecture. No code before we've jointly validated the data structure, integrations and scalability constraints.

Deliverables

  • Process and use case mapping
  • Documented technical architecture
  • Data model (ERD)
  • Phased development plan
02

NestJS Backend Development

2-week sprints

Core application built in NestJS/TypeScript. Modular architecture (domain-driven), unit and integration tests, automatic API documentation with Swagger.

Deliverables

  • Versioned REST API (NestJS/TypeScript)
  • PostgreSQL database with TypeORM migrations
  • Automated tests (Jest, >80% coverage)
  • OpenAPI/Swagger documentation
03

React / Next.js Frontend

2-week sprints

UI built with Next.js and Tailwind. Dashboard, complex forms, data tables and client portal — responsive, accessible and fast.

Deliverables

  • Responsive UI (desktop, tablet, mobile)
  • JWT + RBAC auth by role
  • Documented reusable components
  • Load time < 2s (LCP)
04

Integrations & Third-Party APIs

Varies by scope

Connection to your existing systems (ERP, CRM, business tools) via REST, webhook or custom connector. We handle errors, failure recovery and exchange traceability.

Deliverables

  • API connectors (ERP, Sage, SAP, etc.)
  • Error handling and auto-retry
  • Queryable exchange logs
  • Anomaly alerts
05

Data Migration

2–6 weeks

Extract, clean, transform and import your historical data. Versioned migration scripts, staging environment validation before cutover.

Deliverables

  • Source data audit and mapping
  • Versioned migration scripts
  • Validation report (duplicates, anomalies)
  • Zero-loss cutover with rollback option
06

Testing, Deployment & DevOps

1–2 weeks

Full CI/CD pipeline, separate environments (dev, staging, prod), application monitoring and alerts. Production code is identical to tested code — no surprises.

Deliverables

  • CI/CD pipeline (GitHub Actions)
  • Docker deployment (Railway, Render or your infra)
  • Error monitoring (Sentry)
  • Documented runbook
07

Maintenance & Evolution

Monthly retainer

A dedicated technical contact for fixes, features and team questions. SLA defined contractually, ticket dashboard, monthly review.

Deliverables

  • Priority fixes within 4h (critical SLA)
  • Minor updates included in retainer
  • Source code access (GitHub)
  • Monthly activity report

Maintenance SLA

Response time commitments defined contractually — not just listed on a webpage.

Critical

Total outage or data loss

< 4h (business hours)
Major

Blocking feature, no workaround

< 8h (business hours)
Minor

Bug with available workaround

< 48h (business hours)
Enhancement

New feature or change

Planned together

What We'll Tell You Straight

What we commit to

  • One primary contact throughout the project
  • Source code delivered and owned by you
  • Realistic estimates — we don't lowball to win the deal
  • We say no if a project isn't the right fit

What we don't do

  • Fixed-price projects with undefined scope
  • Maintain vendor dependency after delivery
  • Avoid communicating bad news
  • Subcontract without telling you

Custom or standard?

Custom is the right call when:

  • Your processes are too specific for Salesforce or Odoo
  • You need to connect multiple systems with no turnkey solution
  • You want a client portal or dedicated interface
  • You want full ownership of your code and data

Go Odoo or Salesforce if:

  • Your processes are standard and well-covered by these platforms
  • Your team has no in-house technical resources
  • Your budget is under $15,000
  • You need to be live in under 2 months

Not sure which side you're on? We'll help you figure it out during the free audit — with no bias toward custom.
