But first, I’ll give you the context of Ryan’s finance/analytical oriented role: in particular, Ryan supported the Engineering-Leadership Team at Walmart International B2B2C Cross-Border Marketplace during the integration of Payoneer’s White-Label Working Capital products into the middleware of Walmart International B2B2C Cross-Border Marketplace. Walmart International B2B2C Cross-Border Marketplace’s overall business objective was to enable its B2B2C marketplace’s supply-side (that is listed merchant/sellers on Walmart.com/USA) to sell cross-border to cross-border shoppers on Walmart International’s Walmart.ca (that is Walmart International’s marketplace in Canada). The purpose of the integration of Payoneer’s White-label Working Capital products into the middleware of Walmart International B2B2C Cross-Border Marketplace is enable its listed merchant/sellers on Walmart.com/USA access to working capital - HOWEVER, Walmart International B2B2C Cross-Border Marketplace in this scenario is NOT taking any underwriting or balance sheet risk; Payoneer is the one that is responsible for any risk related to providing merchant/sellers on Walmart.com/USA access to working capital.

The following is the [experience] of Ryan: “Financial Impact of Integration Downtime: Identifying Metrics Process: - The Finance person collaborates with Engineering to understand typical transaction values and volumes, with Customer Success for churn risks and recovery costs, and with Marketing for brand impact analysis. - For each metric, the process involves obtaining historic transactional data, analyzing patterns, forecasting expected transactions during the planned downtime, and estimating averted revenues.- Establishing the relationship with volume and frequency of engagement metrics helps quantify potential churn or service recovery costs based on prior incidents. - Historical data on service-level agreements (SLAs) and operational level agreements (OLAs) can offer insight into guarantees made to customers and the financial repercussions of falling short. Financial Analyses Post-Metrics Identification: - Perform a scenario analysis including best, typical, and worst-case scenarios to estimate financial impact range. - Conduct cost-benefit analysis comparing the financial impact versus the planned benefits of integration. - Model the ROI of any proposed contingency measures such as accelerated workflows or increased customer support post-integration. Excel Modeling: - Create dynamic financial models in Excel that incorporate identified metrics to simulate the impact of downtime. - Develop sensitivity analyses to understand how changes in transaction volume or value affect the overall financial impact.”
