Order fulfillment may take longer during special occasions such as holidays. To avoid cancelled orders due to slow delivery, you can add a custom notification for your customers on the thank you page.

Step by Step Tutorial

From your ShopBase admin site, go to Online Store > Themes > Customize > Checkout Page > More Customization > Put your custom JavaScript code here to add and change some content of Checkout pages.

Paste the following script:

var message = 'We are committed to delivering your orders as soon as possible.';

function addMessageBlock() {
  setTimeout(function() {
    const contentBoxes = document.querySelectorAll('#checkout .main .content-box');
    if (!contentBoxes || contentBoxes.length === 0) {

    const messageBox = '<div class="content-box" id="additional-content-box"><div class="content-box__row"><div class="content-box__wrapper"><p class="os-step__description">' + message + '</p></div></div></div>';
    if (!document.getElementById("additional-content-box")) {
      contentBoxes[0].insertAdjacentHTML('afterend', messageBox);
  }, 500);

window.sbsdk.ready(function() { {
      if (context.type === 'post_checkout') {

You can change your message in var message section upon your wish.

Click Save once finished.
