A transfer between your accounts is not new business cash

The forecast shows income that no customer paid
Suppose you transfer $10,000 from a business savings account to its operating account. The operating account report records an incoming transaction. If the forecast already included the savings balance and treats that transfer as new income, it overstates the business's cash.
Start by deciding which accounts the forecast covers. A clear boundary makes it easier to distinguish money entering the business from money moving within it.
List the accounts included in the opening figure
Record each included account, its balance and the time checked. Identify restrictions or commitments that affect whether funds are available for the planned payments. Do not mix an available-balance figure for one account with an unexplained accounting balance for another.
business.gov.au starts its cash-flow calculation with an opening bank balance. For a forecast covering several accounts, reconcile the included balances before applying that calculation.
Match both sides of an internal transfer
Find the outgoing and incoming entries, including any difference in posting dates. Give the transfer a common reference in your working records. The movement may matter to the operating account's ability to pay, even though it does not increase the combined amount.
Keep fees or other genuine external charges separate. If the two entries do not match, investigate rather than inserting a balancing figure simply to make the summary agree.
Do not assume every related account belongs inside the boundary
An owner's personal account or another company's account is not automatically part of this company's available cash. A proposed contribution or loan needs its own explanation, authority and confirmed availability.
Ask your accountant how to present related-party movements. Avoid quietly combining different entities because they share an owner. The practical forecast should make clear whose obligations and money are being assessed.
Check the effect on each payment account
Even when combined cash is adequate, a scheduled debit may leave the account that holds too little. Show the planned internal transfer and timing in an account-level view, without adding it again as external income in the combined forecast.
Confirm that the transfer is permitted and can be completed when needed. A large combined total does not resolve a restriction or an account-specific processing issue by itself.
Reconcile before promising a creditor payment
Compare the forecast's total with the included bank records and explain the differences. Keep receipts from customers, funding and internal movements visibly distinct.
If correcting the double count reveals a shortage, update the payment plan promptly and discuss it with your adviser. Bring CRP the corrected position if business debts need coordinated attention. A smaller reliable cash figure is more useful than a reassuring total that counts the same money twice.
