Auditing Purchases without SKU using Text Description and Similarity Search

In this paper, we focus on the problem of auditing MRO (maintenance, repair, and operating) purchases that do not have SKU (Stock-Keep Unit) Those specific purchases not only lack SKU but also contain short text descriptions, making the audit processes even more difficult. Our goal is to compare recent purchases with older ones using only the description provided by the purchase process. Therefore, evaluating price differences can uncover possible flaws during the acquiring phase. However, the text of the items that we were working on was very small, with numbers due to the nature of the products and we have a limited amount of time to develop the solution which was 8 weeks. As result, we showed that working using a well-oriented methodology we were able to deliver a successful MVP and achieve the results expected for the client, extended its search database by 30%, and allowed it to have a recovery of up to 20 million dollars.
