In the late 1990s I was the Express Logistics Supervisor for DHL International's HUB in Bahrain. You need clear inventory database with scanning tech, and I imagine secure lock up, you'd need very accurate procedures to avoid liability, alarm/security/ tracking systems. Would you be partnering with parcel services? I'd have to know the scale & locations, plus what research you've already done. Feel free to connect to further clarify & get a to do list.

The problem you're describing — blind delivery attempts wasting driver time and fuel — is well-understood in last-mile logistics, and the solution architecture has matured significantly with modern automation and integration tools. I've worked on workflow automation and field service systems, and here's how I'd think about the technology stack for what you're building:

Core Systems Stack:

1. Dispatch & Routing Automation Engine
This is the heart of the operation. You need intelligent route optimization that accounts for:
- Real-time traffic
- Delivery time windows (confirmed by recipient)
- Driver capacity and shift hours
- Multi-mode handling (courier, van, truck)

Tools to consider: Route4Me, OptimoRoute, or for a more enterprise-grade approach, Microsoft Dynamics 365 Field Service which has built-in resource scheduling (Universal Resource Scheduling) and IoT integration capabilities.

2. Customer Communication & Availability Automation
This is the key fix for the "blind attempt" problem. Before a driver is dispatched, an automated workflow should:
- Send SMS/WhatsApp/email to recipient with a delivery window (1-2 hours)
- Request confirmation or reschedule option
- Feed the confirmed/rescheduled response back into the routing engine automatically

This alone can reduce failed delivery attempts by 30-50%. Power Automate or Twilio-based workflows integrate easily into most dispatch systems.

3. Driver Mobile App
- Turn-by-turn navigation integrated with the route
- Real-time parcel status updates (picked up, en route, delivered, failed + reason)
- Proof of delivery (photo, signature, OTP)
- Automatic ETA push to customer when driver is X minutes away

Off-the-shelf: Onfleet, Tookan, or Bringg. Or build on Power Apps if you want control over the UI and deep CRM/ERP integration.

4. Operations Dashboard (BI/Visibility Layer)
- Real-time map of all drivers and parcel statuses
- KPIs: first-attempt delivery rate, average stops per hour, overtime triggers
- Exception alerts: driver hasn't moved in 20 minutes, parcel unscanned for 2 hours

Power BI connected to your dispatch data gives you this without a custom build.

5. Integration Layer
For multi-mode (courier + van + truck), you'll need a central API layer that:
- Receives orders from e-commerce platforms (Shopify, WooCommerce, custom ERP)
- Routes to the right vehicle/driver pool based on parcel size, weight, urgency
- Sends status webhooks back to senders

Azure API Management or MuleSoft handles this cleanly if you're working with multiple clients or carrier partners.

Lean Startup Approach:
Don't build everything at once. Start with: (1) automated customer notification + reschedule workflow, (2) basic route optimization, and (3) driver mobile app with proof of delivery. These three components alone will show measurable ROI in failed delivery rate reduction within the first month.
