I have 3 invoices that need deleting from the previous accounting period

Continuing the discussion from Unlocking Accounting Period:

Can I unlock the previous years accounting period, delete the 3 invoices, then lock the accounting period again without it having an effect on this years’ accounts?

If you unlock an accounting period and remove invoices it will changes the accounting figures for that year, most likely the sales balances and debtor control (assuming you’re removing sales invoices).

Thank you for your reply… Does this mean that I have to ask my Accountant to make an adjustment when they do this years end of year accounts?

Yes that would be the case.
