Records

The admin card everyone forgets

Longer note · updated October 2026

Side work isn't only the work. Invoices, records and messages take real time, and they're the first thing to be skipped.

Give admin its own card

Once a week, a short slot just for admin. Many people use Sunday morning or Friday lunch.

What goes on it

  • Send invoices for finished work
  • Check payments that arrived, and which are late
  • Note income and costs for the week
  • Reply to non-urgent messages

Why it matters

Side income is usually taxable, and records make that simpler. Unsent invoices are also the most common way people work for free without meaning to.
