How 3PLs can choose from the best inventory management companies

Warehouse managers running a growing 3PL know that efficient inventory management can directly impact their profit margins. A higher (or faster) inventory turnover leads to higher profitability.

The top inventory management companies and software solutions for 2025 include Fishbowl, NetSuite, Cin7, and Veeqo. These platforms provide tools for tracking stock across multiple locations, automated reordering, and barcode scanning. This allows warehouse managers and 3PLs to reduce stockouts, improve inventory accuracy, and streamline order fulfillment for multiple clients.

In this guide to inventory management companies, we will cover everything you need to know to make the best choice.

What types of inventory management companies serve 3PLs?

Not all inventory management companies are built the same. In the 3PL space, solutions typically fall into three categories:

1. Legacy WMS providers

Traditional Warehouse Management Systems (WMS) were built to control warehouse operations: order receiving, picking, packing, and shipping. These systems are still efficient and configurable even after decades. However, they typically rely on heavy customization to support new workloads.

Many 3PLs also find their architecture to be monolithic and on-prem or hosted in older cloud environments. Legacy WMS solutions can manage inventory accuracy within four walls, but expanding beyond that (billing automation, advanced integrations, or robotics) requires significant development work. Plus, these systems are also difficult to scale.

2. ERP inventory modules

Enterprise resource planning (ERP) platforms like NetSuite offer built-in inventory management modules as part of a larger financial and operational suite. These systems work well for accounting, reporting, and high-level supply chain management. But for 3PLs, ERP inventory modules don’t perform well enough.

These platforms weren’t designed for multi-client environments with granular client-level rules, ownership separation, or warehouse-specific workflows. Yes, they can track inventory, but handling complex 3PL billing, client permissions, and operational nuances pushes them beyond their intended design.

3. Modern Fulfillment Management Systems (FMS)

Modern Fulfillment Management Systems (FMS) like Logiwa empower a new  wave of inventory management. These platforms are built specifically for high-volume order fulfillment and multi-warehouse operations.

They unify inventory management, order management, billing, and integrations into a single ecosystem. FMS platforms are API-first and can easily connect with marketplaces, automation systems, robotics, and financial tools without requiring any customization.

Do legacy WMS and ERP inventory modules hold 3PLs back?

Many mid-market 3PLs still rely on legacy systems because “that’s what we’ve always used.” But as they grow, limitations in older systems become more visible.

Heavy customization is one of the most common challenges. Many legacy WMS platforms require extensive configuration and code-level changes to support new clients or workflows. This stretches implementation timelines to months.

ERP inventory modules present a different type of rigidity. Their data structures are built for centralized enterprise control instead of multi-tenant 3PL environments. As a 3PL provider, you might need to implement workarounds to manage separate client permissions or unique storage fees.

Static systems also limit agility. When you integrate a new technological solution or automation partner, these systems can’t keep up with them. If your system is not built around APIs and real-time data exchange, you have to rely on manual processes or brittle custom connections.

Over time, these constraints slow onboarding, reduce operational flexibility, and make it harder to respond to market shifts in the supply chain. Explore more about legacy inventory management systems in this guide to warehouse management systems.

Which features should 3PLs prioritize when evaluating inventory management software?

When reviewing inventory management companies, mid-market 3PLs and warehouse managers need to focus on capabilities that support scale and visibility. The following evaluation criteria will help you make the right choice:

• Multi-warehouse visibility in real time. A strong platform should provide network-wide visibility across all facilities and clients. Inventory levels, movements, and order statuses should be updated in real time on data dashboards.
• Client-level ownership and controls. 3PLs operate in shared warehouse environments. The system must allow granular separation of stock items by client, along with configurable rules for storage, picking, and shipping. User permissions should reflect client-specific access.
• Automated billing and financial integrations. Revenue leakage often occurs in manual billing processes. An efficient warehouse inventory management software should support automated calculation of storage fees, pick-and-pack charges, and value-added services.
• API-first architecture and automation readiness. An API-first system makes it easier to integrate conveyor systems, autonomous mobile robots (AMRs), automated storage solutions, and external supply chain systems. This flexibility supports long-term growth without requiring deep reconfiguration.

With this level of transparency and flexibility, warehouse managers can do stronger inventory forecasting and capacity planning.

How are modern FMS platforms redefining inventory management?

Modern FMS expand the role associated with inventory management companies. Besides tracking stock, these systems connect inventory, orders, and billing in one place.

With a modern FMS, your inventory management, order fulfillment workflows, billing rules, and reporting tools operate within the same environment. Moreover, your data flows seamlessly across modules, which reduces duplicate entries and reconciliation issues.

An efficient FMS platform also supports flexible rules engines. This allows 3PLs and warehouse managers to handle multiple fulfillment models at once, including B2B, DTC, and subscription services.

Since workflows are configurable through the platform, your client onboarding also becomes faster. This enables operations teams to launch new accounts faster and with greater consistency. As a growing 3PL, this unified structure provides you with a strong foundation for operational efficiency and scalable growth.
