What is a Shopify Delivery Calendar?
A Shopify delivery calendar (also called a delivery date picker or ship date picker) is a checkout tool that lets customers choose their preferred delivery or shipping date when placing an order. This interactive calendar displays only valid dates based on your rules.
Unlike estimated delivery dates (which only show when an order might arrive), a delivery calendar gives customers control—selecting from available dates based on product lead times, ZIP code zones, shipping methods, and capacity limits.
For brands selling furniture, perishable food, made-to-order products, or managing complex fulfillment, a delivery date picker eliminates "Where's my order?" support tickets, prevents failed deliveries, and increases checkout conversions by giving customers certainty.
Key features of a delivery calendar:
- Block specific dates (holidays, weekends, production days)
- Set delivery dates by ZIP code or postcode zones
- Control dates by product type or shipping method
- Manage daily delivery capacity limits
- Sync selected dates to your order management system
How it works:
1. Set rules by available days, product, ZIP code and shipping method
2. Customers see only valid delivery dates at checkout
3. Orders automatically tagged with selected date
4. Dates sync to your fulfillment system
Common use cases:
- Furniture brands with 2-8 week lead times
- Food & beverage with delivery window requirements
- Gifting with specific occasion dates
- B2B with scheduled delivery routes
- Made-to-order with variable production times
Complete Checkout Automation: Dates, Rates and Checkout Validation.
Flare combines delivery date selection, shipping rate automation, product page estimation, and checkout validation in one integrated app. Most stores need 3-4 separate apps for complete checkout control—Flare gives you everything together.
What Flare automates:
Delivery date selection – Customers choose delivery dates based on your rules
Shipping rate calculation – Automatic carrier rates by ZIP, product, and method
Product page estimation – Show delivery dates before checkout
Checkout validation – Enforce order rules and minimums
Replace multiple disconnected apps with one integrated solution that works seamlessly.

“We've seen a big uplift in conversion rate. In fact, numerous customers have already commented on the fact they chose us because we offered a choice of delivery date.”
Harry (Managing Director), Millie & Jones - Furniture
“We used to get constant messages like ‘When’s my order shipping?’ and 'But, I won't be home that day' — now, zero. It’s been a huge time saver for the team and customers.”
Rob (Director), Flip Aquatics - Live Fish
Why Most Delivery Calendars & Date Pickers Fail?
They create lost sales, manual edits and support tickets.
Customers pick invalid dates → missed deliveries & refunds
No product/ZIP/method logic → inaccurate dates
Manual edits and support tickets to fix dates
Checkout support limited (best on Shopify Plus)

How Flare's Date Picker Works.
Smart delivery logic. Seamless customer experience.
1. Configure delivery rules.
Set lead times, cutoff times, or logic by ZIP, product, or shipping method.
2. Accurate checkout.
Customers only see valid dates - no confusion, edits, inquiries or refunds.
3. Orders are ready to ship.
Orders are automatically tagged and synced to your fulfillment system.
Set Up Delivery Rules in Minutes, not Months.
From basic date selection to complex fulfillment logic — no coding required.
Shipping Rate Automation: Accurate Rates, Zero Manual Work.
Calculate precise shipping rates based on ZIP code, product weight, dimensions, order value, and shipping method. Built-in carrier integration with FedEx and UPS for real-time rate calculation.
Rate automation features:
Carrier API integration for live rates (FedEx, UPS)
Custom rate rules by ZIP code or zone
Free shipping thresholds by order value
Product-based rate adjustments
Shipping method automation (standard, express, overnight)
Multi-warehouse origin support
Rates update automatically based on selected delivery date. When customers choose express delivery for tomorrow, they see tomorrow's date AND the express shipping rate together—no confusion, no manual adjustments.
Stop losing margin on shipping. Manual rate calculation costs you 3-5 hours per week plus margin leakage from undercharging. Flare automates the entire process.

Replace 4 Separate Apps With One Integrated Solution.
Most Shopify stores cobble together checkout functionality from multiple apps. This creates conflicts, support headaches, and higher costs.
Typical setup:
Delivery date picker: $10-40/month
Shipping rate calculator: $20-50/month
PDP delivery estimation: $15-30/month
Checkout validation: $10-30/month
Total: $55-150/month for 4 disconnected apps
Problems with multiple apps:
❌ Apps don't communicate (date picker doesn't know about rates)
❌ Conflicting rules (date says available, validation says blocked)
❌ 4 separate support teams to deal with
❌ Complex setup and ongoing maintenance
❌ Higher total cost for worse experience
Flare combines all 4 for $39-$599/month:
✅ One rule engine (dates, rates, validation all use same logic)
✅ One support team
✅ One app to maintain
✅ Features work together seamlessly
✅ Lower total cost than separate apps
Integrated solution costs less than separate apps while delivering better results.
