Custom software & app development

Software shaped around the way you already work.

Web applications, client and staff portals, internal tools, mobile apps, APIs and integrations between the systems you already pay for. Santre builds what off-the-shelf software cannot do and keeps it running after launch.

Start with a workflow review and a scoped first release.

Overview

Custom Software & Application Development

Santre's custom software service designs, builds and supports web applications, client and employee portals, internal workflow tools, mobile apps and integrations for Canadian businesses. It is for organizations that have outgrown spreadsheets and email-driven processes, need two systems to share data without re-keying, or want a customer-facing tool that no packaged product provides. Because Santre also runs infrastructure and security, applications are hosted, monitored, backed up and patched as part of the same engagement rather than handed over at launch.

Who it is for

  • Teams running core processes in spreadsheets and email
  • Businesses re-keying data between two systems
  • Organizations that want a client or partner portal
  • Companies with an ageing internal application no one can maintain

What’s included

From the first workflow map to the next release.

Web applications and portals

Browser-based tools for staff, clients or partners, with sign-in, roles and an audit trail.

  • Client and partner portals
  • Internal operations and approval tools
  • Dashboards and self-service forms
  • Single sign-on with Microsoft Entra ID

Integrations and APIs

Connect accounting, CRM, ERP, scheduling and Microsoft 365 so data moves once and stays consistent.

  • API development and integration
  • Data synchronization between business systems
  • Webhook and event-driven workflows
  • Legacy system data extraction
How it works

Integrations are built with retries, logging and alerting so a failed sync is noticed and replayed, rather than discovered weeks later as a reconciliation problem.

Mobile and field apps

Apps for technicians, drivers and site staff that work where the office network does not reach.

  • Cross-platform mobile apps
  • Offline-capable data capture
  • Photo, signature and barcode capture
  • Device management for company phones

Modernization and support

Replace or extend software that has become a risk, then keep it maintained.

  • Legacy application modernization
  • Hosting, monitoring and backups
  • Security updates and dependency maintenance
  • Feature roadmap and release management

When to consider it

Signs it is time to act

  • A core process depends on one spreadsheet and one person
  • Staff copy the same information into two or three systems
  • Clients ask for status updates you could let them see themselves
  • An internal application runs on an unsupported platform
  • No packaged product fits the way your operation works

How Santre delivers it

A clear process from first review to ongoing care

  1. Map

    Document the current workflow, the people involved and where time or accuracy is lost.

  2. Define

    Agree scope, a first release that is useful on its own, and how success will be measured.

  3. Build

    Develop in short iterations with working demos, then test with real users before launch.

  4. Run

    Host, monitor, back up and patch the application, and plan the next releases together.

Scope

Technologies and boundaries

Platforms commonly in scope

  • TypeScript, React and Next.js
  • Node.js and REST APIs
  • Microsoft Power Platform
  • SQL and cloud databases
  • Azure and AWS hosting
  • Microsoft Entra ID single sign-on

Where this service ends

Packaged software that already fits — such as Microsoft 365 or Santre Stack — is usually the better answer, and Santre will say so. AI-driven automation of a process is scoped under AI & Intelligent Automation; reporting on top of the data under Data & BI.

Frequently asked questions

Questions about Custom Software

Buy when a product fits most of the process without heavy workarounds. Build when the process is a genuine differentiator, when products force staff into duplicate entry, or when you need to connect systems that do not integrate. Santre reviews both options before recommending a build.

Ownership and licensing terms are set out in writing in each statement of work before development begins.

Santre can host, monitor, back up and update the application and continue developing new features, or hand it over with documentation to your own team.
