What is an internal tool?

An internal tool is software built for employees to run day-to-day operations inside a company. It connects to internal data sources, enforces business rules, and takes care of repetitive workflows like approvals or data entry. Unlike customer-facing products, these tools are not marketed or sold. They exist to help teams work faster and make fewer mistakes. Good internal tools give non-technical staff safe, permissioned access to databases and services through simple interfaces. They often replace messy spreadsheets, ad-hoc email processes, and one-off scripts with a single, reliable application.
