Frequently Asked Questions About Custom Software Development
How do we decide between custom software development and off-the-shelf SaaS tools?
Off-the-shelf tools work well for standard accounting or email. Custom software is the better investment when your competitive advantage relies on a specific operational workflow, multi-role approval process, or unified dashboard that generic SaaS platforms cannot support without expensive workarounds.
Who owns the source code and database when SaivaTech builds custom software?
You retain ownership of your custom application codebase, database schemas, and business data upon project completion, with zero mandatory per-seat licensing fees.
Can you modernize an existing spreadsheet or legacy desktop application?
Yes. We frequently migrate businesses from disconnected Excel files or outdated desktop software to secure, cloud-hosted web applications with role-based staff logins and automated backups.
