How to Order Diaries and Planners on COS
Ordering diaries and planners on COS follows the same process as any other product on the COS website. Here is the step-by-step process.
Log in to your COS account
Go to cos.net.au and log in using your account email and password. Logging in before browsing ensures contracted pricing, any applicable discounts, and your saved order history are all visible as you shop.
Navigate to Diaries 2027
From the homepage, use the top navigation menu or the search bar to find the Diaries 2027 category. You can browse all available products or use the filter panel on the left to narrow by type (diary, planner, desk pad), format (day to a page, week to view, month to view), size (A4, A5, pocket), brand, and price range.
Select your product and check the details
Click on any diary or planner to view the full product page, including size, page count, cover type, date range, and any available variants. Check the product details carefully before adding to cart, particularly the year edition if you are ordering ahead for the following calendar or financial year.
Add to cart and review your order
Add the quantity required to your cart. Review the cart to confirm product name, edition year, quantity, and unit price before proceeding. If you have a promotional or contracted discount, it should appear here.
Complete checkout
Proceed through checkout, confirm your delivery address, select your preferred delivery option, and submit the order. You will receive an order confirmation email to the address associated with your COS account.
How to Find Last Year's Diary Orders and Reorder
If your team or organisation ordered diaries last year and you want to reorder the same products for the coming year, you do not need to search the catalogue from scratch. Your COS account stores your full order history, making it straightforward to find what you ordered previously and place a new order.
Log in and go to Order History
Log in to your COS account at cos.net.au. From your account dashboard, navigate to Order History. This displays all orders placed under your account, listed by date.
Filter by date range
Use the date filter to find orders placed in the same period last year, for example January to March if you typically order at the start of the calendar year, or October to November if you order ahead of the financial year. This narrows the list to the relevant ordering window.
Identify your diary order
Locate the order or orders that included diaries or planners. Click into the order to see the full product list, including product names, SKU codes, quantities, and the edition year purchased.
Add items to cart for reorder
From the order detail view, you can add individual items back to your cart. Check that the product you are adding is the current year edition, as diary products are updated annually. If the exact product has been updated or renamed, use the SKU or product name to search for the current equivalent.
Complete checkout
Proceed through checkout, confirm your delivery address, select your preferred delivery option, and submit the order. You will receive an order confirmation email to the address associated with your COS account.
COS tip: If you manage diary ordering for a large team or organisation and would like help reconciling last year’s order against this year’s requirements, contact your dedicated COS account manager. They can pull your order history and prepare a draft reorder list for your review.
What to Do If Your Discount Is Not Showing at Checkout
COS offers a discount on essential business supplies and may also apply contracted or promotional discounts to eligible accounts. If you are expecting a discount to appear on your diary order and it is not visible in the cart or at checkout, do not complete the order until the issue is resolved. Completing the order at the wrong price requires a retrospective adjustment, which takes longer to resolve than addressing it before checkout.
Additionally, some offers are only valid until a certain period and may no longer be applicable for orders after the date.
Confirm you are logged in to the correct account
Discounts are applied at the account level. If you are browsing without logging in, or if you are logged into a different account than usual, contracted or promotional discounts will not appear. Log out and log back in to the account your discount is associated with.
Confirm the discount applies to diaries
Some promotional or contracted discounts apply to specific product categories and may not cover all diary or planner products. Check whether the discount you are expecting has any category exclusions. For diary discounts, the offer excludes Personnel Boards, Writing Instruments, Undated Planner Refills, Notebooks, Teacher Planners, Custom Branded Diaries, and Promotional Products.
Check the cart subtotal and discount line
In the cart, look for a discount or promotion line below the product subtotal. If the discount has been applied it will appear here. If the line is not visible, the discount has not been triggered for this order.
Contact your account manager or COS customer service
If the discount should apply and is still not showing after checking the above, do not proceed with the order. Contact your COS account manager directly or call COS customer service on 1300 COS COS (1300 267 267). Have your account number and the products in your cart ready. The team can confirm whether the discount applies to your order and, if needed, apply it manually before you complete the purchase.
Important: Do not complete your order if the expected discount is not showing. Contact COS customer service or your account manager before checkout. Retrospective price adjustments after an order has been placed take longer to process than resolving the issue before the order is submitted.
Terms and Conditions for Ordering Diaries
All orders placed on cos.net.au, including diary and planner orders, are subject to the COS Terms and Conditions of Sale. These set out the terms that govern purchases, delivery, returns, and any promotional pricing.
Key points to be aware of when ordering diaries include:
- Year editions: Diaries are year-specific products. Once a calendar year has begun, the prior year’s edition is typically non-returnable unless the product is faulty. Check the edition year carefully before ordering, particularly when ordering in the second half of the year for the following year.
- Bulk and custom orders: Large volume diary orders or custom branded diary orders may be subject to separate terms, including minimum order quantities, lead times, and non-cancellation conditions once production has commenced. These will be confirmed in writing at the time of quote.
- Returns and exchanges: Standard diary products purchased through COS are subject to the COS returns policy. Products must be in original, unopened condition to be eligible for return. Personalised or custom branded products are non-returnable once production has commenced.
- Promotional pricing: Any promotional discount applicable to diary orders will be displayed in the cart. Promotional pricing is subject to availability and may be time-limited or subject to minimum order quantities as specified in the promotion details.
The full COS Terms and Conditions of Sale are available at cos.net.au/terms-and-conditions. If you have a question about the terms that apply to a specific diary order, contact your COS account manager or the COS customer service team before placing the order.
Frequently Asked Questions
How can I see a list of diaries we bought last year to reorder for next year?
Log in to your COS account at cos.net.au and navigate to Order History from your account dashboard. Use the date filter to find orders placed in the same period last year, then click into the relevant order to see the full product list including diary names, SKU codes, and quantities. From the order detail view you can add items back to your cart. Check that any diary you are reordering is the current year edition before completing the order. If you need assistance pulling your order history or preparing a reorder list, contact your COS account manager.
While placing an order, I can't see the 5% discount applied. How do I proceed?
Do not complete the order until the discount issue is resolved. First, confirm you are logged in to the correct account, as discounts apply at the account level and will not show if you are browsing without logging in. Check whether the discount line appears below the cart subtotal. If the expected discount is still not showing, contact your COS account manager directly or call COS customer service on 1300 267 267 before checkout. The team can confirm whether the discount applies to your order and arrange for it to be applied before you submit. Completing the order at the wrong price requires a retrospective adjustment, which takes longer to resolve. Do note that diary discounts are only applicable up to a certain date and may no longer be applicable for orders past it.
Are there any Terms and Conditions for ordering Diaries?
Yes. All orders placed on cos.net.au, including diary and planner orders, are subject to the COS Terms and Conditions of Sale, available at cos.net.au/terms-and-conditions. Key considerations for diary orders include: checking the edition year carefully before ordering; noting that custom branded or personalised diary orders are non-returnable once production has commenced; and being aware that promotional pricing may be subject to minimum quantities or time limits as specified in the promotion details. Contact your COS account manager or COS customer service if you have a specific question about the terms that apply to your order.
Can I order diaries without a COS account?
Yes. You can browse and purchase diaries and planners on cos.net.au without a COS account. However, logging in to an existing account before ordering gives you access to your order history for reordering, any contracted or promotional pricing applicable to your account, and a saved address book for faster checkout. If you do not have a COS account and would like to set one up to access these benefits, visit cos.net.au/register or contact the COS customer service team on 1300 267 267.
Can I order next year's diaries before the year begins?
Yes. COS typically makes the following year’s diary and planner range available for order in the second half of the current year, often from mid-year onwards. Ordering ahead of the new year is recommended for larger quantity orders, particularly if you need specific diary formats or branded options, as popular editions can sell out. Use the Diaries and Planners category filter and select the relevant year to find available products for the coming year.
How do I get help with a diary order?
For any query about a diary order, contact your COS account manager directly if you have one, or call COS customer service on 1300 267 267 during business hours. You can also use the live chat or contact form on cos.net.au. If your query is about a discount not applying, an order placed in error, or the terms applicable to a custom branded order, contact COS before completing or amending the order rather than after.
Browse the full COS diary and planner range at cos.net.au, or contact your dedicated COS account manager to reorder last year’s range, check your discount entitlement, or get a quote for a custom branded diary.
