What SAC code should software developers use on invoices in India?

Software programming, web development, and cloud engineering services in India fall under SAC 998314 with an 18% GST rate.

Should freelance developers bill hourly or by sprint milestone?

Milestone-based sprint invoicing (e.g. 50% upfront, 30% staging, 20% production deploy) is recommended because it prevents scope creep and eliminates unpaid bug-fix loops.

When should developers transfer production code repository ownership?

Never transfer root repository rights, API secret keys, or cloud hosting credentials until the final milestone invoice has cleared.
