The Quote Engine is the heart of the courier selection process. It ensures real-time access to courier partner rates by dynamically calling multiple APIs based on pickup/drop PIN codes, weight, and package type. Standardising this flow guarantees accurate pricing, enables meaningful comparisons between service levels (air vs surface), and ensures users see transparent, all-inclusive prepaid costs. By breaking the logic into defined steps—input handling, API normalisation, GST/fuel surcharges, and display formatting—we maintain control over how pricing is represented and allow consistent business logic to be applied across couriers with differing API formats.

02

In a system where no Cash on Delivery (COD) is allowed, the payment flow becomes a critical checkpoint for authentic orders. This step ensures that only fully-paid shipments are processed, which reduces failed pickups, fraudulent orders, and reconciliation issues. The flow is tightly coupled with Razorpay, and AWB generation is gated behind payment confirmation, preventing misuse of logistics resources. By enforcing strict rules here—no wallet deductions, no postpaid logic - we streamline operations and create a zero-leakage payment pipeline that improves trust with both users and courier partners.

03

The Generation of the Air Waybill (AWB) and printable shipping label is a pivotal moment in the booking lifecycle. It represents the successful transition from user intent to operational commitment. This step confirms that a courier has accepted the shipment, assigns a trackable ID, and provides a scannable label that logistics teams will use throughout the delivery journey. Automating this process immediately post-payment ensures instant confirmation to the user, faster pickup scheduling, and clear data records in our CMS. Each label generated includes QR/barcode metadata to support last-mile scanning and fraud prevention.

04

Shipment Visibility is key to a modern delivery experience. By integrating tracking API and attaching each shipment to real-time status updates (via WhatsApp and email), we offer users transparency and reduce inbound support tickets. Every key milestone - pickup, in transit, out for delivery, delivered - is both captured in our Database and communicated to the user. This section ensures our system is proactive, not reactive, and positions us competitively against other players by offering consumer-grade shipment intelligence.

05

Courier API can fail. Network connections may drop. Addresses might be invalid. That’s why robust fallback logic is essential. This layer prevents dead ends in the user experience by retrying API calls, removing unavailable couriers, or prompting users to correct input errors. By anticipating points of failure and building graceful exits or alternate paths, we preserve trust and avoid friction. This logic is also foundational for SLA with courier partners, as it ensures we only route bookings when systems are verified operational.

06

As shipment volumes grow, performance and infrastructure resilience become key success factors. This structure ensures the system can Scale to Handle 50,000+ Daily Orders without failure or delay. The platform can distribute load and maintain responsiveness through queue-based AWB generation, asynchronous webhook handling, and modular API integrations. The architecture is designed to support horizontal scaling, multi-region redundancy, and usage spikes during seasonal peaks.
