Transportation management software development is the process of building a custom TMS that plans, executes and tracks the movement of goods — from order and route to delivery, billing and settlement. CIT Software builds custom TMS and logistics platforms as a Vietnam-based offshore partner, and hands over the full source code so the system is entirely yours.
Built for how your logistics actually runs
Off-the-shelf TMS suites are expensive and rarely match a specific operation — multi-modal shipping, external carriers, unusual billing rules or a regional network. A custom TMS fits your exact workflow, integrates with your ERP and partners, and gives you one place to run orders, fleets, tracking and freight costs. We build for logistics operators, 3PLs, freight forwarders, distributors and manufacturers that have outgrown spreadsheets and generic tools.
Key modules and features
A TMS earns its value in the depth of its modules — this is where control, efficiency and cost savings come from. Below are the core modules we build; each can be tailored to your operation.
Order & shipment management
- Create and manage transport orders and shipments.
- Support for road, sea, air and multi-modal transport.
- Shipment statuses, milestones and document attachments.
- Consolidation of orders to optimise loads.
Route & trip planning
- Route planning and optimisation by distance, time and cost.
- Trip scheduling with recurring and one-off runs.
- Load and capacity planning per vehicle.
- Map-based visualisation of routes and stops.
Fleet & driver assignment
- Assign vehicles and drivers, with clash and availability checks.
- Vehicle records, capacity and maintenance status.
- Driver records, licences and schedules.
Real-time tracking
- GPS tracking of vehicles and shipments in real time.
- ETA calculation and delay/deviation alerts.
- Route playback and historical trip logs.
- Proof of delivery with signature or photo.
Carrier & partner management
- Manage external carriers, sub-contractors and their capacity.
- Dispatch loads to partners when internal fleet is full.
- Carrier rates, performance and cost tracking.
Freight billing & settlement
- Rate cards, quotes and automated freight cost calculation.
- Customer invoicing and carrier settlement.
- Cost reconciliation and margin per shipment.
Reporting, portal & administration
- Dashboards: on-time rate, cost, utilisation and exceptions.
- Exportable reports for operations and finance.
- Customer portal for booking, tracking and documents.
- Accounts, roles and permission management.
- Integration with ERP, WMS and accounting systems.
How a custom TMS cuts logistics cost
A transportation management system pays for itself by removing waste that spreadsheets hide. Route and load optimisation reduces empty miles and fits more shipments into each vehicle; automated dispatch and carrier selection put every load on the cheapest suitable option; and real-time tracking cuts the phone calls and manual check-ins that eat operator time. Accurate freight costing and settlement stop revenue leaking through under-billing and unreconciled carrier invoices, while on-time and utilisation reporting show exactly where money is lost. For most operations the biggest gains come from two places: better vehicle utilisation and tighter cost control on external carriers — both of which a custom TMS is built to manage.
Integrations that make a TMS powerful
A TMS delivers the most value when it is connected, not an island. We integrate the platform with your ERP and accounting so orders and invoices flow automatically; with warehouse (WMS) systems so dispatch reflects real stock and dock schedules; with GPS and telematics devices for live tracking; and with customer and carrier portals so partners self-serve bookings, documents and status. Clean APIs mean the TMS becomes the operational hub of your logistics, sharing one source of truth across sales, operations and finance instead of leaving each team with its own disconnected view.
Who we build TMS platforms for
We build for third-party logistics providers (3PLs), freight forwarders, transport and trucking companies, distributors and manufacturers managing their own delivery networks. Because the platform is custom-built, it fits your modes, rules and partners. For fleet-focused operations we also build fleet management software, and for connecting many carriers with shippers, a logistics marketplace platform.
Start focused, then expand
A TMS doesn’t have to launch with every module. We often start with the core — orders, planning and tracking — to deliver value early, then add carrier management, freight settlement and analytics as adoption grows. Phasing the build keeps the budget and risk under control while your team gets used to the new system.
How we build your TMS
Our process is transparent and low-risk: a discovery and business-analysis phase to map your logistics workflow, integrations and rules; architecture and prototype you approve; development in phased, testable modules with regular demos; rigorous testing; then deployment, data migration, training and source-code handover. We can then maintain and extend the platform as your network grows.
Why build with an offshore team in Vietnam?
Building a TMS with a Vietnam-based team gives logistics companies senior engineering and business-analysis capacity at a fraction of local cost, with English-speaking project management and full ownership of the platform. For a system you’ll run for years, that ownership matters — no licence lock-in, and full control of your data and roadmap. It is a key reason companies outsource software development to Vietnam. For broader needs, see our custom software development services.
Security, roles and data ownership
A TMS holds sensitive operational and commercial data — customer orders, carrier rates, margins — so security and access control are built in from the start. Role-based permissions make sure operators, finance, drivers and customers each see only what they should, and audit trails record who changed what. Because the platform is custom and you receive the source code, you also control where the data lives and how it is hosted, rather than trusting a third-party vendor’s cloud with your logistics intelligence. For a system that sits at the centre of your operation and holds years of shipment and cost history, that ownership is not a technicality — it is control of one of your most valuable business assets, and the freedom to evolve the platform without asking anyone’s permission.
Frequently asked questions
How much does custom TMS development cost?
It depends on the modules, integrations and users. We usually phase the build so you invest module by module and see value early, and quote per project after a discovery phase.
Can it integrate with our ERP and accounting?
Yes. We build clean APIs and integrations so the TMS connects with your ERP, WMS, accounting and partner systems for one source of truth.
Do we own the source code?
Yes. CIT hands over the complete source code on delivery, so you own the platform, the data and the roadmap with no per-seat licence fees.
Does it support multi-modal and external carriers?
Yes. We build for road, sea, air and multi-modal transport, and include carrier management so you can dispatch loads to external partners when needed.
