Where I can find receipts/invoices for QuickBooks online usage

option 1:

• disable JavaScript

  

option 2:

• use an extension and block individual scripts

option 3:

• use Tampermonkey script:

  // ==UserScript==
  // @name           disable CTRL+SHIFT+T
  // @description    stop website from highjacking keyboard shortcuts
  //
  // @run-at         document-start
  // @include        *
  // @grant          none
  // ==/UserScript==
  
  keycodes = [84];
  
  (window.opera ? document.body : document).addEventListener('keydown', function(e) {
  if (keycodes.indexOf(e.keyCode) != -1 && e.ctrlKey) {
      e.cancelBubble = true;
      e.stopImmediatePropagation();
  }
  return false;
  }, !window.opera);

I contacted QuickBooks support and they gave the following link:

QB does not understand the "Quick Method". (Which in any case is not really all that "Quick".)

My recommendation:

Do not track HST on MOST expenses, only on those rare expenditures that qualify for treatment as ITC (Input Tax Credits) under the Quick Method - typically capital expenditures, for example, but research this further for your client's benefit. For most expenses, "operating expenses" according to CRA, the HST paid is just part of the expense.

Calculate the HST "manually" (Sales + HST collected) x rate (remember to reduce the "Quick Method rate" by 1% on the first $30,000). Then calculate the "discount" (actual amount collected, minus the manual calculation). Enter the "discount" as a Sales Tax Adjustment using the Sales Tax Item for "Adjustment to HST on Sales". For the "Sales Tax Adjustment Account" use something like "Miscellaneous Income" - yes, this is income subject to income tax, but then the HST paid on expenses is also part of your deductible expenses.

QB will not correctly report the Sales and Other Revenue (Line 101 on the return) so do not file online directly from QB. Instead choose "File by Paper or Other Method", then use either NETFILE or paper.
