Logistics & Supply Chain
Engineering Teams That Move Your Business Forward
Build systems that optimize operations, improve visibility, and scale with your growth. We help logistics companies—from freight brokers to enterprise shippers—build technology that keeps goods moving efficiently.
What We Build
Software Development for Logistics & Supply Chain
From transportation management to warehouse systems, we build the technology that powers efficient supply chains.
Transportation Management
Custom TMS solutions for carriers, brokers, and shippers. Load planning, carrier management, rate shopping, and freight audit—built for your specific workflows.
Warehouse Management
WMS solutions for 3PLs and distribution centers. Inventory tracking, pick/pack optimization, labor management, and integration with automation systems.
Route Optimization
Dynamic route planning that reduces miles, fuel, and time. Handle complex constraints—time windows, vehicle types, driver hours—with real-time re-optimization.
Real-Time Tracking
Live visibility into shipments, vehicles, and assets. GPS integration, ETA predictions, exception alerts, and customer-facing tracking portals.
Inventory & Demand Planning
Demand forecasting, inventory optimization, and replenishment planning. ML-powered predictions that reduce stockouts and carrying costs.
Driver & Field Apps
Mobile applications for drivers and field workers. Proof of delivery, electronic logging, inspection checklists, and offline-capable operation.
Common Challenges
Problems We Solve for Logistics Companies
Logistics comes with unique operational and technical challenges. Here's how we address them.
Lack of End-to-End Visibility
Shipments in transit are a black box. You need real-time visibility across modes, carriers, and handoffs. We build tracking systems that show you exactly where everything is.
Legacy System Integration
Your TMS doesn't talk to your WMS. Your ERP is disconnected from carrier systems. We build integrations that connect your tech stack and eliminate manual data entry.
Manual, Paper-Based Processes
Drivers still use paper logs. Proof of delivery is a photo texted to dispatch. We digitize operations with mobile apps and automated workflows that reduce errors.
Scaling Operations Efficiently
Growing volume but can't hire dispatchers fast enough. We build automation and optimization that lets you handle more with less—route optimization, auto-dispatch, and smart load building.
Why Salt
Why Logistics Companies Choose Salt
We've helped logistics companies modernize systems and build new platforms. Here's what makes our teams different.
Logistics Domain Expertise
We've built TMS, WMS, and fleet management systems. Our teams understand the industry—modes, carriers, regulations, and the operational realities of moving freight.
Real-Time at Scale
Logistics generates massive data volumes. We build systems that handle millions of tracking events, process them in real-time, and keep your visibility dashboards current.
IoT & Device Integration
From GPS trackers to temperature sensors, we integrate with the devices that power modern logistics. We handle the complexity of device management and data ingestion.
Optimization Algorithms
Route planning, load building, scheduling—we implement optimization algorithms that save miles, reduce costs, and improve on-time performance.
Reliable & Resilient
Logistics runs 24/7. We build systems with proper redundancy, graceful degradation, and offline capabilities that keep your operations running.

FAQs
Common Questions About Logistics Development
Answers to questions we frequently hear from logistics and supply chain companies.
Can you integrate with existing ERP and WMS systems?
Yes, integration is a core part of what we do. We've built integrations with SAP, Oracle, NetSuite, Manhattan Associates, Blue Yonder, and many other ERP and WMS platforms. We use EDI (X12, EDIFACT), APIs, flat files, and custom connectors to ensure seamless data flow between systems. We understand the complexities of logistics data—EDI 204s, 214s, 990s, and the rest.
Do you have experience with real-time tracking and IoT?
Yes, we've built real-time tracking systems that handle millions of location updates daily. We work with GPS devices (Samsara, KeepTruckin, Geotab), telematics providers, IoT sensors for temperature/humidity, and cellular/satellite networks for remote areas. We design for scale—handling high-frequency data efficiently while keeping infrastructure costs manageable.
Can you help optimize our route planning?
Absolutely. We've built route optimization solutions using both commercial engines (Google OR-Tools, HERE, Routific) and custom algorithms for specialized requirements. We handle complex constraints—delivery time windows, vehicle capacities, driver HOS regulations, priority stops, multi-stop routes—and can integrate with your existing TMS or dispatch systems.
Do you build mobile apps for drivers?
Yes, driver apps are a common project for us. We've built apps for proof of delivery (photo, signature, barcode scanning), electronic logging (ELD compliance), pre/post-trip inspections, navigation integration, and communication with dispatch. We build for offline operation—essential when drivers are in areas with poor connectivity.
Can you help modernize our legacy TMS?
We've helped multiple logistics companies modernize legacy systems. We take an incremental approach—wrapping legacy systems with APIs, building modern frontends, and gradually migrating functionality without disrupting operations. We understand you can't just turn off systems that run your business.
What experience do you have with carrier integrations?
Extensive. We've integrated with major carriers (UPS, FedEx, DHL, USPS) and hundreds of regional carriers via EDI and API. We've built rate shopping engines, tracking aggregators, and label generation systems. We also have experience with freight marketplaces and load board integrations (DAT, Truckstop).
Can you handle the data volumes logistics generates?
Yes, we architect for logistics-scale data. This means time-series databases for tracking data, stream processing for real-time events, proper data partitioning, and efficient storage strategies. We've built systems handling tens of millions of events per day while keeping query performance fast.
How quickly can you add developers to our logistics project?
We can typically onboard developers within 2-3 weeks. Our logistics-focused developers understand the domain—TMS, WMS, carrier integrations, EDI, and supply chain workflows. For urgent needs, we can often move faster with developers from our existing logistics practice.
