Technology services / Custom Software Development
Custom software.
Built around you.
For businesses whose workflows need more than off-the-shelf software. Build enterprise applications, connect existing systems, develop products or modernise legacy software around your users and operations.
Custom Software Development
- Enterprise Application Development
- Web Application Development
- Mobile Application Development
01 / Overview
Custom software for your workflows and existing systems
Perivana develops enterprise applications, web and mobile software, SaaS products and integrations. Start with the users, business rules and exceptions that existing software does not handle. Define a first release around those tasks, then connect the required data, permissions and systems.
Turn the workflow into acceptance criteria
A useful brief explains who can do what, which records change and what happens when a step fails. These details make the software easier to estimate, review and hand over.
02 / What we deliver
Expertise you can
put to work.
Enterprise Application Development
Build applications around business rules, user roles, approvals and operational reporting.
Web Application Development
Develop browser-based workflows with agreed access controls, integrations and acceptance checks.
Mobile Application Development
Connect iOS, Android or cross-platform applications to the APIs and workflows your users need.
Product Engineering
Define and build a first release for a SaaS product or digital platform, with later features tracked separately.
Integration Services
Connect systems and third-party APIs with agreed data ownership, permissions and failure handling.
Software Modernization
Review legacy dependencies and plan incremental changes to application code, data and deployment.
Plan your project
Turn your workflow into a clear brief.
When this service fits
- Business processes that existing software cannot support
- Disconnected applications and repeated manual work
- A product idea or a legacy system that needs to evolve
Scope to agree
- User journeys, requirements and acceptance criteria
- Application features, integrations and data migration
- Testing, deployment, documentation and handover
What to bring
- The users, workflows and problems to address
- Existing systems, APIs and data constraints
- Priority features, decision-makers and budget range
Deliverables, timing, pricing and ongoing support depend on the agreed scope. Use these points to shape your enquiry.
Explore websites and web applicationsDefine the finish line
Make the first release testable before it is built.
A useful software brief describes the people, decisions and data behind a workflow. Agree observable acceptance criteria so that progress can be reviewed against a business task.
A bounded first version
Choose the workflows and user roles that belong in the first release. Record exceptions and approval rules, and keep a separate list of later ideas so that changes remain visible.
Data and integration rules
Identify the source of truth for each record, existing system interfaces and data-migration needs. Agree access permissions, audit needs and behaviour when an external service is unavailable.
Acceptance and ownership
Define who approves the work, the test scenarios and the environments needed for review. Agree source-code access, deployment instructions, documentation and the support boundary in the engagement terms.

Practical answers
Frequently asked questions.
Every business has unique software needs. Here are some of the most common questions we hear from clients:
How should changes to scope be handled?
Record the requested change, its purpose and its effect on delivery, dependencies and cost. Decide whether it replaces an existing item or becomes additional work before implementation. A visible decision log makes it easier to protect the first release while retaining useful ideas.
What should we ask for at software handover?
Agree the repository and access arrangements, setup instructions, environment configuration, migration steps, test evidence and operating notes. Include known limitations and ownership of external accounts. The exact handover package and intellectual-property terms should be stated in the engagement agreement.
How can we scope an initial version?
Identify the core users and the smallest set of workflows that make the software useful. Separate essential features from later enhancements, document integrations and agree acceptance criteria. This gives the project a clear basis for estimating effort and reviewing progress.
How long does custom software development take?
Timing depends on workflows, integrations, data migration and acceptance requirements. Define the first release and review points before estimating delivery; later features can be planned separately.
Can you integrate with our existing systems?
Yes, where suitable APIs, data access and permissions are available. Scope the records exchanged, source of truth, synchronisation rules and failure handling, then validate the integration against agreed scenarios.
Do you provide ongoing support and maintenance?
Support, updates and optimisation can be included in a separate or ongoing scope. Agree coverage, response arrangements, responsibilities and the change process before the application is handed over.
Which industries do you serve?
Our BFSI experience includes digital transformation and application monetization. We also discuss software needs in healthcare, retail, e-commerce and enterprise IT, with workflows and sector requirements defined for each project.
