Your customer has a full cart. They’re ready to buy. Then they see “Ships in 3-5 business days” and start doing mental math. When does that actually arrive? Will it get here before the birthday party?
That moment of uncertainty kills conversions.
Delivery-related concerns are among the top reasons shoppers abandon carts, yet 41% of major ecommerce checkouts still don’t display a delivery date. For mid-market and enterprise brands managing complex fulfillment networks, the problem compounds with:
- Inventory spread across multiple warehouses, stores, and 3PL partners
- Varying carrier performance and transit times by region
- Service level options that change delivery promise calculations entirely
Pipe17’s Estimated Delivery Date (EDD) capability solves the delivery uncertainty problem by calculating accurate, specific delivery promises in real time and serving them wherever your customers are buying.

How Estimated Delivery Date (EDD) Works
When a delivery promise is requested, EDD evaluates your entire fulfillment network to determine the most accurate delivery options available. Pipe17:
- Analyzes inventory availability across all your warehouses, stores, and fulfillment locations
- Factors in carrier service levels, transit times, operating hours, holidays, and capacity constraints
- Returns a specific estimated delivery date, not a vague window
- Records the delivery promise and passes it to fulfillment, so orders ship as promised
Pipe17’s EDD is engineered for checkout-speed performance. Instead of pulling fulfillment data from across the entirety of your operational systems at request time, EDD draws from a dedicated, continuously-updated data source built specifically for delivery promise calculations. The service is always running with no cold starts or spin-up delays, so delivery promises are returned in milliseconds, not seconds.
EDD also accounts for multiple fulfillment scenarios behind the scenes. It prioritizes single-location fulfillment for the best customer experience. When no single warehouse can fill the entire order, EDD intelligently considers split shipment options. In those cases, the delivery promise date reflects when the last package arrives, customers see a clear note that items will ship in multiple packages, and your backend systems receive the routing guidance needed to fulfill accurately.
Delivery Promises for Every Selling Channel
Pipe17’s EDD is an API-first capability, which means it works wherever your customers are shopping. Embed delivery promises on product detail pages, in the cart, at checkout, through a headless implementation, or within agentic workflows.
For Shopify merchants, a reference Shopify EDD implementation is available as a starting point for surfacing delivery promises in your storefront.
As commerce moves toward AI-driven purchasing, EDD gives AI agents reliable, programmatic access to delivery data so they can make purchasing decisions on behalf of consumers. Paired with Pipe17’s onX compliant MCP Server, merchants get a robust operational backbone for agentic commerce: from surfacing inventory and delivery promise dates through to order orchestration, fulfillment, and delivery.
Multiple Service Level Delivery Promises, One API Call
Pipe17’s EDD goes beyond returning a singular delivery estimate. Merchants can request multiple delivery options (Ground, Express, Overnight, Same-Day, etc.) in a single call. Each option comes back with its own estimated delivery date, giving your customers, or AI agents, the ability to choose based on urgency and budget.
Pipe17 also stores delivery promise(s) and includes them in an order’s shipping request(s), ensuring fulfillment teams are aware of the promise made to your customer. Accurate delivery promises at checkout are one of the most effective ways to compete on customer experience, and EDD makes them possible without requiring you to build a massive fulfillment infrastructure from scratch.
Why Delivery Promise Accuracy Matters for Brands and 3PLs
For brands operating across DTC, B2B, marketplaces, retail, and agentic channels, EDD closes a critical gap in the pre-purchase experience. Delivery uncertainty is a conversion problem, a customer satisfaction problem, and a driver of unnecessary support volume all at once. Giving shoppers a specific, reliable estimated delivery date at checkout addresses all three.
For 3PLs and fulfillment service providers managing millions of orders across hundreds of clients, Pipe17’s estimated delivery date capability adds measurable value to your business and clear differentiation from the competition. Your merchant clients get better checkout conversion. Their customers get accurate delivery promises. And the fulfillment guidance embedded in every EDD response helps optimize how orders flow through your fulfillment network.
The Operational Layer, Extended
EDD extends Pipe17’s Order Operations Platform from post-purchase order orchestration into the pre-purchase checkout experience. Because Pipe17 manages order operations across your selling channels, fulfillment nodes, and back-office systems, EDD draws on the same operational data that powers your fulfillment workflows to generate delivery promises that reflect reality, not estimates based on static rules.
This is what it looks like when your operational layer works end-to-end: from the moment a customer asks “when will it arrive?” through fulfillment, shipment, and delivery. Better delivery promises. Higher conversion. Fewer “where’s my order?” tickets.
