This is a more complex question than it first seems. Your description of cash basis accounting was too simplistic. The differences between accrual and cash basis accounting have more to do with philosophy than just with when transactions show up on the P&L statement.
Technically, you are correct that cash basis accounting records both revenues and expenses when money actually changes hands. But that is not, in fact, how you have been using Manager. By your act of recording payslips, you are accruing liabilities to pay employees. Under double-entry accounting, those credits must be matched by debits. So the salary/wage expenses show up in an expense account and the new liabilities show up in Employee clearing account. That keeps your books in balance.
If you were truly using cash basis accounting, you would not enter the payslip until you were ready to pay it. But do you want to leave those real liabilities unrecorded? That would be as bad as not recording a short-term business loan liability until the day you paid it off. That, of course, is one of the greatest shortcomings of cash basis accounting: your true financial position is not reflected in such situations.
You might ask, “How is this different from Accounts receivable on the balance sheet and Sales on the P&L?” It really isn’t. Both can be suppressed under cash basis accounting until money changes hands. That also distorts your financial position, but is somehow more acceptable. Accountants don’t seem to argue about that issue. On the other hand, many do argue about whether to suppress payroll liabilities and expenses until paid. In fact, some tax authorities have special procedures dictating when those payroll expenses will be recognized. If Manager were to automatically suppress payroll-related account postings until the employee is paid, users in some countries would be unable to comply with requirements of their authorities. So this is not an easy question to resolve.
Meanwhile, if you don’t want payroll expenses and liabilities to appear until you pay the employees, your best bet is to delay entry of payslips. Better yet, switch to accrual basis accounting and be confident that your financial statements accurately represent current position and performance rather than the partial view you get from cash basis accounts.
