The Challenge

Is Your HR Software Holding You Back?

Off-the-shelf platforms like Gusto are great—until they're not. As your company grows, you hit a wall. Workarounds pile up, manual data entry creates errors, and the lack of custom features slows down your most critical operations. You're paying for a solution that creates more problems than it solves. The real cost isn't the subscription fee; it's the lost efficiency, compliance risks, and frustrated employees. It's time to build a platform that works for you, not against you.

Success Stories

Real-World Results from Custom HR Platforms

Replacing a Patchwork of HR Tools

Technology / SaaS

A 500-employee SaaS company was struggling with a disjointed system of Gusto for payroll, a separate HRIS for employee data, and spreadsheets for tracking complex sales commissions. This led to constant manual data reconciliation, payroll errors, and a lack of unified reporting.

"CIS didn't just build us software; they built us an operational backbone. Our payroll processing time is down by 75%, and for the first time, we have a single, reliable source for all our people data. It's been a game-changer for our finance and HR teams."

Michael Harper, CFO, ScaleUp SaaS Inc.

Our Solution:

  • Developed a unified platform with a custom commission calculation module.
  • Integrated with their Salesforce CRM to pull sales data automatically.
  • Built a robust reporting dashboard for real-time financial and HR analytics.
  • Migrated all data from their previous systems with zero downtime.

Healthcare

A rapidly expanding healthcare provider with 2,000+ employees across 15 states faced a compliance nightmare. Their existing payroll system couldn't handle the complex web of state-specific labor laws, tax withholdings, and healthcare credentialing requirements, putting them at significant risk.

"Compliance was our biggest headache. The custom platform CIS built has an AI-powered compliance engine that has saved us countless hours and gives us peace of mind. Their understanding of complex regulatory environments is second to none."

Jenna Clay, Chief Compliance Officer, HealthPro Group

Our Solution:

Got Questions?

Frequently Asked Questions

The cost to develop a platform like Gusto varies significantly based on complexity. An MVP with core payroll and HRIS features can range from $80,000 to $150,000. A full-featured, enterprise-grade platform with advanced benefits administration, multi-state compliance, and third-party integrations can cost $250,000 to $500,000+.

Development timelines depend on the feature set. A focused MVP can be launched in 4-6 months. A more comprehensive solution typically takes 9-12 months. Our AI-enabled development PODs and agile methodology help accelerate this timeline by optimizing workflows and reducing manual coding efforts.

While Gusto is excellent for many businesses, a custom solution is necessary when you need: unique payroll rules (e.g., complex commissions, union requirements), deep integration with your proprietary ERP/CRM, specific compliance and reporting workflows, or a fully branded employee experience. A custom platform provides a competitive advantage through operational efficiency that off-the-shelf software cannot match.

Security is paramount. Key considerations include end-to-end data encryption (at rest and in transit), role-based access control (RBAC), compliance with regulations like SOC 2, GDPR, and CCPA, regular security audits and penetration testing, and secure third-party API integrations. We are a SOC 2 certified company, and security is embedded in our development lifecycle from day one.

Absolutely. Seamless integration is a core strength of custom development. We build robust APIs to connect your new HR platform with existing systems like accounting software (QuickBooks, Xero), ERPs (SAP, Oracle), project management tools (Jira), and any other proprietary software your business relies on, creating a unified data ecosystem.
