What It Is
Version control is a detailed history of every change made to a set of files. Each time a developer saves a meaningful step, the system records what changed, when and by whom. Git is the most widely used version control tool, and services like GitHub host Git projects online. It is like the edit history in a shared document, but built for code and able to rewind to any earlier point.
Why It Matters for Your Business
For a small business, version control is insurance for custom work. If a new feature breaks your booking page, a developer using Git can see exactly what changed and roll it back in minutes. It also means the knowledge is not trapped on one person’s laptop. If you switch developers, the full history of your site’s custom code can be handed over cleanly.
Good to Know
Version control tracks code, not your content or database. Your blog posts, orders and form entries still need regular backups. If you are paying for custom development, ask where the code is stored and make sure the repository (the project’s storage in Git) is in an account your business owns or can access.
