Project Overview

With a mission to streamline and simplify its internal expense management operations, Security Industry Specialists (SIS) engaged our team to develop a custom web and native mobile expense management application.

Since the internal platform would integrate with their existing Angular and Node-developed systems, SIS selected Upstate Interactive based on our extensive experience building enterprise applications and proficiency in using JavaScript and Angular technologies.


Previously, the company’s legacy expense management system lacked advanced features and responsiveness. SIS aimed to provide employees with a simplified and convenient way to submit and approve expenses but needed enterprise software developers to build advanced features into a custom application.


Working closely with SIS’ internal team, we built a cross-platform application to streamline submission and approval processes.

Providing a web app, native mobile app, and custom distribution mechanism for mobile app downloads, we incorporated advanced OCR technology and performative features into the system, including:

  • Image scanning and storage
  • Credit card data feeds
  • Bulk uploading of receipts
  • Rapid swiping to approve and reject

The expense management system is used by 10,000+ employees.


Our workflow helps us create and produce the best work possible.

  1. 1

    Discovery & User Stories

    Phase 1 involved reviewing the existing application, refining software requirements and user stories, conducting technical research, mapping the architecture, and deciding on languages and frameworks.

  2. 2

    MVP Build for Beta Testing

    Phase 2 incorporated building an MVP within SIS’ existing tech stack, implementing designs, performing internal testing, setting up manual releases and automated deployments, and moving code to a single repository.

  3. 3

    Development for Version 1

    Phase 3 entailed transitioning into SIS’ staging and production environments, building and testing additional features, making design and bug fixes, CICD work, and building the custom distribution mechanism for the mobile app.

  4. 4

    Employee Rollout

    Phase 4 consisted of a phased rollout of the web and mobile application to employees and ensuring successful implementation within each department.

“We were looking to work with a development team that was familiar with Angular and could work within our existing stack and environments. We had specific requirements for the project and knew we would need to pivot throughout the development process. Upstate Interactive proved to be very flexible and adaptable when curve balls arose, bringing on new talent when needed. They’ve been an invaluable partner in bringing the project to life.”
