Hi Yuksel, thank you for choosing QuickBooks Online. Our software includes a match suggestion tool that identifies transactions based on the same amount and within a date range of 90 days before and 20 days afterward.
Since the cheque you deposited on January 29 was issued on January 15, you can create an Invoice or Sales Receipt in QuickBooks dated January 15 to record the income. When your bank feed syncs and displays the deposit, QuickBooks will automatically identify the match. All you need to do is click Match.
While you completed the work three months ago, please note that the income is generally recorded in the month you received the payment unless you’re using accrual accounting rather than cash accounting.
For payroll, since you are paying yourself, you may consider setting yourself up as an employee in QuickBooks Payroll to simplify tracking your earnings. It is also advisable to consult a tax accounting professional for guidance on handling payroll taxes specific to your business structure.
Feel free to revisit this thread if you have further questions or need clarification.
