Great app once configured, but support needs improvement We have used Addition for several years and, once correctly configured, the app works very well. It reliably displays our Australia Post eParcel rates at checkout and gives us the flexibility we need for products with different sizes and packaging requirements. However, I do need to be honest about the support experience. Recently, we had an issue causing incorrect shipping rates at checkout, and getting assistance through the app’s normal support channel was very difficult. We received little to no response and ultimately had to contact the AMP team through support for another one of their apps before we could get proper help. Once we were connected with Anoop, the experience improved considerably. He arranged access to our store, involved the technical team, kept us updated and eventually identified and fixed the packaging issue. He was helpful and transparent, and advised that they are now hiring more dedicated Australian support staff. The app itself is very useful and works well once everything is set up correctly. I hope the planned improvements to support are implemented, because reliable and timely assistance is especially important when shipping rates suddenly stop working at checkout.

We use this app for shipping integration with Australia Post, but also for managing free ship thresholds. We cannot access the data in the app, every change needs to go through their support team. We have made a decision to increase charges with upcoming post rate increases - 3 WEEKS LATER we are still waiting for a response from their support team. Being unable to implement a change ourselves, and having no support means we are now actively looking for an alternative - not the job you want a week out from year end. Very disappointing - service has progressively worsened since AMP bought this app from the original developer.

I've loved the convenience of this app for a few years, but I think it may have become abandonware now :( I've been trying to get in contact with support regarding a change from Shopify that seems to have broken this app's shipping calculations for some addresses and not others, but they haven't replied. I'm hoping they see this and I can delete this review, but if they don't reply I'll be forced to switch apps as soon as practically possible.

This is an OK app. It's certainly better than manually processing postage, but it's soooo clunky. It's just full of needless clicking to do basic things and waiting for screens to load and refresh. - Updating product sizing is needlessly complicated with minimal tools for bulk operations, and these sizes don't sync with the main Shopify DB or vice versa - The download Labels button is white, where the Delete button is bright RED. The Delete button is also the right most button. Really bad UI design. Download should be the right most button and should be Blue or Green - Fulfilment and Label windows default to everything unselected.... Default should be selected. Why would I have just done all the shipping if I didn't want to print out the labels? Default assumption is that after creating a fulfilment, I want to include everything for all following processes. - Labels - Ditto from above. I shouldn't have to select all when I've just gone through the shipping process to check all dimensions and create the shipment - No table view for packages in shipment. A tabular view is far more efficient that opening up a window for every single package. - Bulk options should be available in all subscriptions. - Should be able to bulk enter packages and deal with orders and bulk fetch prices instead of doing it one-by-one. This shouldn't be a gate-kept feature behind a paywall. It's basic workflow - Why do I have to name EVRYTHING or at least be prompted? Default names for records (Fulfilments, labels, etc) should be a setting in the app and automated. Asking the user EVERY SINGLE TIME is very inefficient. - No grouping of packages and no-reordering of package options in the app. This app is clearly just a cash cow for the developers. The current owners are not the original programmers, and it's clear from the clunky workflow that they're not users of the app either. It could be made way, WAY better, but it's been the same clunky interface for years with no improvements. I've only listed a few of the issues with the app. There are many more subtle changes that could vastly improve the app.

I spent over 10 hours trying to get everything working today and ended up losing business because of this app. No response from support at all. The app is clunky generating labels was painfully slow, often taking around 30 seconds per label. Customers were receiving errors saying their address couldn’t be shipped to, even though I tried everything. Some orders would work, others wouldn’t, for no clear reason. I upgraded the app after using it successfully for 5 or 6 years, hoping to use the new label feature and apply shipping rules like free shipping over a certain amount. That’s when everything went downhill. No customer support. No live chat. Nothing. You’re a tech company 24+ hour response times are not acceptable. I switched to “Australia Post Rates & Labels” and they responded immediately and helped me with setup. Honeslty wasted a whole day and lost money stressful to say the least.

Absolutely terrible App. All shipping settings deleted overnight without warning and no technical support provided to investigate thoroughly. We are constantly getting messages from customers asking why we don't ship to their country (USA/China/UK) when we have been shipping to those countries for years. App is full of bugs and is now causing us to lose customers as there is only so many times you can apologise to the ones who are unable to order. No phone support at all which should be an instant red flag for anyone reading this. DO NOT USE THIS APP - there are plenty of others out there and I strongly urge you to chose a competitor that actually allows your products to be sold - unlike this one. We sell around 5000 orders each year so this is not simply a few instances.

Finally found an app that does what we intended from the start in a semi elegant way of forwarding customize shipping rates to our customers particularly when we have a wide mix of parcels being sent. What truly sets this company apart for us is the exceptional service provided by Laura. She takes full ownership of her work, which shows in her seamless communication, flexibility in accommodating our requests, and takes the time to understand our business needs as if they were her own. I’d highly recommend them without hesitation!

2026 Update: Still loving this app, support got back to me today quicker than ever! Love this app and the support team! Integrates seamlessly with our Shopify and whenever I have an issue the support team are always there to help look into my problem and come up with a solution. If you’re looking for an Australia post plug-in, this is the one!
