Services / Development & Integration
Custom Software Development
We would rather configure than code. When a real gap remains — a pricing engine, a field app, a customer portal — we build it as a maintainable product with tests, documentation and a repository you own.

- Best fit for a defined operational gap the ERP cannot close, or a customer-facing experience that needs to sit on top of it.

What’s included
Scope, stated before we start
Six work-streams that make up a standard engagement. Anything outside them is priced separately and named in the proposal — never absorbed quietly.
Discovery & solution design
A written specification with user stories, data model, integration points and acceptance criteria — plus an explicit build-versus-configure decision for every requirement.
Web & mobile applications
Portals, field-service and warehouse apps, approval and workflow tools. Modern stacks, responsive by default, offline-tolerant where the work happens without signal.
API-first architecture
Documented REST endpoints, authentication, versioning and rate limits so today's custom app becomes tomorrow's integration point rather than tomorrow's dead end.
Security & testing
Threat modelling, dependency scanning, automated test coverage on business logic and a pre-release penetration review on anything internet-facing.
Deployment & observability
CI/CD pipelines, staged environments, logging, uptime and error alerting — so a failure is a notification, not a phone call from a customer.
Handover & support
Source code, architecture notes, runbooks and a walkthrough for your team, with an optional SLA. No hostage code.
Outcomes
What changes when this is done properly
These are the three differences clients describe six months after go-live — not feature claims.
- A specification signed before code is written
- Documented APIs the next project can reuse
- Repository and runbooks owned by you

Who it’s for
Industries where this comes up most
Each links to how the service is shaped for that sector — the requirements differ more than vendors admit.
Our approach
The same four phases, applied to this scope
Reused deliberately. A consistent method is what makes a fixed price honest and a date holdable.
01
Discover
Process mapping before software selection.
We walk the floor and the ledger. Two to three weeks of structured interviews and document tracing produce a current-state process map, a data-quality baseline, and a written list of the decisions your systems cannot currently answer.
02
Design
One target architecture, agreed on paper.
Chart of accounts, item and customer master rules, approval hierarchies, integration contracts and reporting model are designed together — not discovered during build. You sign off a blueprint, not a demo.
03
Deliver
Configure, migrate, test, train — in that order.
Iterative configuration with fortnightly conference-room pilots. Data migration runs three times before go-live: trial, dry run, and cutover, each reconciled to the closing trial balance. Users train on their own data.
04
Sustain
Hypercare, then measurable adoption.
Four to eight weeks of hypercare with named owners and a burn-down of issues. Then a governance rhythm: master-data stewardship, monthly close review, and a Power BI adoption dashboard that shows whether the system is actually being used.
Related case study
One inventory engine behind three sales channels
Wholesale, retail and e-commerce moved onto one Odoo inventory and pricing engine, with integration contracts, batch and expiry control, and margin reported at SKU and customer level.
We had eleven versions of our item master across three companies. Techlyst rebuilt it as one governed standard and then made sure it stayed that way. Stock accuracy went from an argument to a number.
Three tests: does the logic belong to the ledger, will it survive an ERP upgrade, and who will maintain it. Transactional and financial logic stays in the ERP. Specialised UX and high-change logic goes outside, connected by API.
Typically .NET or Node on the back end, React or Next.js on the front end, SQL Server or PostgreSQL for data, Azure for hosting. We pick for maintainability in your market, not novelty.
Yes, in full, on final payment — including repository history, deployment configuration and documentation. That is stated in the contract, not implied.
After a technical audit: dependency and vulnerability review, test coverage, architecture assessment and a remediation estimate. We will be straight with you about whether it is worth carrying forward.
