Distinguish earned, invoiced and received money

An invoice is not the same as money in your account. Keep a list of expected payments with due dates, and record received income separately when it arrives. This prevents a promising invoice total from hiding a short-term cash shortage.

For each payment, note the client or source, amount, currency and receipt date. Record transaction fees separately if you want to understand the difference between the invoice amount and what you received.

Build a calendar of essential costs

List the costs that have a due date: rent, utilities, subscriptions and other commitments. Add irregular costs that are foreseeable, such as annual renewals. Compare the dates with expected receipts rather than comparing monthly totals alone.

Illustrative example: you expect 15 million VND on the twentieth, but 8 million VND of bills are due on the fifth. Even if the month is profitable overall, the calendar shows a timing gap. The record should make that gap visible before the bills fall due.

Separate reserves from available spending

Moving money to a reserve account is a transfer. Identify what it is reserved for, such as a future bill or a business cost, so it is not mistaken for discretionary spending. Set reserve amounts using your own commitments and circumstances.

Tax obligations depend on your jurisdiction and work arrangement. This worksheet does not calculate tax or recommend a tax rate. Record any confirmed obligation separately and consult official local guidance or a qualified adviser for the actual amount.

Compare several months rather than one good month

Review received income, essential spending and cash remaining across multiple months. Label unusual one-off payments so they do not become the baseline for recurring commitments. A simple range can be more informative than a single average.

Keep business and personal transactions distinguishable even when you use one tracking tool. Export a copy regularly if you need to reconcile with another system. Expense tracking supports planning; it does not replace bookkeeping or professional tax advice.
