Abstract: Introduced is a technology for processing transactions on behalf of a merchant employing a legacy system, where the processing includes managing inventory data and bundle pricing data associated with transactions occurring at various point-of-sale (POS) devices that include both legacy and non-legacy POS devices. Briefly described, the technology involves a payment processing system (PPS) working in coordination with a legacy merchant system. The PPS includes a payment processing database system, a adapter module installed at the merchant system, and a payment processing engine installed at a cloud-based server system. The payment processing engine, via the adapter module, can receive the most up-to-date inventory data and bundle pricing rules from the legacy merchant system. Based on the bundle pricing rules, the payment processing engine can compute one or more minimum-price carts that apply pricing discounts to eligible items for transactions occurring at the POS device(s) associated with the PPS.

Abstract: Techniques for classifying a merchant based on content derived from crawling a website associated with the merchant are described. As an example, a payment processing service may receive an indication to crawl a website associated with a merchant. The website may be accessible by a Uniform Resource Locator (URL). The payment processing service may access the website via the URL and may analyze, via a web crawler, a structure of the website to derive content of the website. Based at least in part on a previously trained data model and the content of the website, the payment processing service may determine a classification of the merchant. The classification may identify the merchant as a fraudulent merchant or may identify the merchant as a candidate for a particular service offered by the payment processing service.

Abstract: This disclosure describes techniques for intelligent payment capture in mixed fulfillment transactions. For example, the techniques described herein may include generating a purchase ticket associated with multiple items in a mixed fulfillment transaction. The purchase ticket may facilitate conducting a mixed fulfillment transaction in which a payment instrument is authorized for the cost of the multiple items in the mixed fulfillment transaction, with partial payment captures being made as items are fulfilled without requiring additional authorizations.
