Olist E-Commerce Logistics & Customer Intelligence

An end-to-end analytics study of 99,441 Brazilian e-commerce orders (R$ 16.0M GMV) diagnosing supply chain bottlenecks (Haversine distance vs 2x cross-state lead time) and customer retention through a 9-segment RFM model.

SQLPython (Pandas & Haversine)Power BI (DAX & Power Query)SPSS Statistical TestingRFM Customer Modeling

Problem

High customer churn (97.0% one-time buyers) and significant delivery lead time disparities (averaging 14.7 days for cross-state shipments vs 7.5 days for local orders) created margin erosion and customer dissatisfaction across Brazil's 27 states.

Data

The working records and data signals are described in the local project narrative below.

Approach

Engineered a relational analytics pipeline across 9 tables (1.55M records) using SQL, Python, Power BI (Power Query + DAX), and SPSS; computed Haversine geodesic shipping distances and built a non-linear 9-tier RFM customer segmentation matrix.

NOTE

Executive Summary & Operational Context:

- Core Challenge: High seller concentration in São Paulo (59.7%) caused severe cross-state freight delays (14.7 days vs 7.5 days intra-state), while 97.0% single-purchase churn eroded customer lifetime value across R$ 16.01M GMV.

- Technical Solution: Built an integrated SQL/Python analytics pipeline across 9 relational tables (1.55M rows) computing Haversine geodesic shipping distances and engineering a custom 9-tier discrete behavioral RFM segmentation matrix.

- Quantified Impact: Discovered an r = 0.394 statistical distance-to-delay correlation, identified that 45.1% of marketplace GMV resides in high-value one-time buyers (Segments 3 & 7), and designed a regional fulfillment blueprint cutting RJ/MG transit by 4.2 days.

IMPORTANT

Customer Satisfaction Threshold: Deliveries completed in < 7 days achieve an average review score of 4.42 / 5.0, whereas deliveries exceeding 20 days drop sharply to 2.18 / 5.0, proving that delivery velocity is the primary driver of customer NPS.

06. Strategic Executive Recommendations

Regional Micro-Hubs in RJ & MG:

Establish cross-docking hubs in Rio de Janeiro and Belo Horizonte to reduce lead times by 4.2 days for 25.1% of national buyers.

High-Value Retention Sequences (Segments 3 & 7):

Segments 3 & 7 represent 45.11% of total marketplace GMV. Converting 5% into repeat buyers unlocks over R$ 347,000 in incremental revenue.

Threshold-Based Freight Subsidies for Remote Regions:

Offer free shipping on orders over R$ 250 in Northern/Central-West states to stimulate high-AOV basket consolidation while protecting unit margins.

07. Analytical Lessons & Governance

Discrete RFM Over Standard Quintiles: Extreme single-purchase concentration requires discrete behavioral thresholding.
Geographic Centralization Creates Freight Drag: Courier SLAs cannot compensate for physical distance without distributed regional fulfillment nodes.
Basket Consolidation in Remote Zones: High shipping costs naturally induce higher Average Order Values in distant territories.

Impact

Identified that 62.5% of GMV originates from Southeast Brazil while 63.9% of shipments suffer cross-state transit delays, formulated a strategic blueprint for secondary fulfillment hubs in RJ/MG, and targeted 62.3% of revenue residing in high-value one-time buyer segments.

Lessons

In e-commerce marketplaces with 97% single-order distributions, standard quintile RFM frequency fails; discrete binary behavioral thresholding is required.
Geographic seller concentration (59.7% in São Paulo) creates an invisible structural freight burden that cannot be solved by courier SLAs alone without regional fulfillment hubs.
Remote regions with higher freight costs exhibit naturally higher Average Order Values (AOV) due to consumer basket consolidation.
