What do you like best?
DEAR seems to be able to do it all - It integrates with a number of platforms for shipping, eCommerce, accounting... And has different sections to allow businesses to customize it (though with limits) to their own needs. I use DEAR with Quickbooks and Shopify together. Having Shopify push all of our sales from our physical and online store is great, and DEAR captures these real time. There seem to be so many features in DEAR that I'm not using right now, though I could see the benefit for other business. They allow for inventory tracking, dynamic movement, sale tracking and fulfillment, purchase order placement and tracking, and even allows you to track assembly of products. They've recently lifted their 20,000 SKU limit on accounts.
The interface is fairly easy to use, especially for simple transactions (like product movement, sale fulfillment for in-stock items...). One major benefit of DEAR is the ability to limit the access that each user has to each section of DEAR - sensitive information doesn't need to be shared with everyone and items that can cause problems with the database can be set to view-only status.
Dear support is also quite good. Sometimes it takes some back-and-forth with the member of the support team to get them to understand the problem, but if there is a solution it's usually explained well.
What do you dislike?
While DEAR does try to offer a lot of features, the ones that they have can be very limiting. As mentioned, we use Shopify to push sales to DEAR, however, DEAR uses its own labelling/numbering system so it can be very hard to track the specific sale. Additionally, as a safe-guard, DEAR does not let you undo a lot of actions. For example, a location that has been used to store a product will forever be in the system, even if it hasn't been used for years. While this prevents inconsistencies with the 'history' of a product/item, it can create a lot of confusion for users when logging locations or searching for products. Along this line as well, any product that was used in one way shape or form in the system cannot be deleted. So even if it was created or used by accident you're stuck with it there. DEAR is continually adding new features and refining the ones they have, but it can take a long time (even for popular requests) to get changes to the system.
Recommendations to others considering the product
Figure out what exact inventory processes you need in your business. Do you need to assemble products? Do you change your products from when they arrive to when they are sold? Do you need to keep track of expiry dates? Do you need purchase, storage and sale information on one platform? Do you need multiple people with regular access to the system? DEAR allows you to do all of these things in some capacity, but do thorough research first!
What business problems are you solving with the product? What benefits have you realized?
In most eCommerce platforms there's no sophisticated way to track inventory all the way from purchasing to storing to selling and shipping. DEAR helps manage a lot of that. Despite its shortcomings in some areas, it's allowed us to keep track of our frequently changing inventory.
