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.
Discovery & Architecture
2–4 weeksWe 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
NestJS Backend Development
2-week sprintsCore 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
React / Next.js Frontend
2-week sprintsUI 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)
Integrations & Third-Party APIs
Varies by scopeConnection 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
Data Migration
2–6 weeksExtract, 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
Testing, Deployment & DevOps
1–2 weeksFull 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
Maintenance & Evolution
Monthly retainerA 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.
Total outage or data loss
Blocking feature, no workaround
Bug with available workaround
New feature or change
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.
