GDP Compliance: The Complete Guide to Requirements and System Support

Good Distribution Practice (GDP) is not a recommendation you can opt in or out of - it is a legally binding obligation for any company that distributes medicines. This article gives you an overview of what GDP requires, and how an ERP system can support these requirements, rather than them becoming an administrative burden alongside day-to-day operations.

What is GDP, and who does it apply to?

GDP describes the quality requirements for the procurement, storage, transport and supply of medicines throughout the entire distribution chain. The requirements apply to wholesalers, distributors and logistics companies that handle medicines between the manufacturer and the pharmacy or other end recipient. The purpose is to ensure that a medicine’s quality and integrity remain intact all the way from factory to patient.

GDP vs. GMP vs. GLP - a brief clarification

The three abbreviations are often confused, but they cover different parts of the value chain:

• GMP (Good Manufacturing Practice) applies to the actual manufacturing of the medicine.
• GLP (Good Laboratory Practice) applies to laboratory work, typically related to testing and research.
• GDP (Good Distribution Practice) applies to distribution - storage, transport and handling after production is complete.

As a logistics or distribution company, GDP is primarily what’s relevant to you, but the interface with GMP often becomes clear when products are handed over between manufacturer and distributor.

The concrete requirements: traceability, temperature, documentation

The GDP requirements span several areas, but three come up again and again as particularly central for logistics companies:

• Traceability: Every movement of a product through the distribution chain must be documented and traceable.
• Temperature control: Many medicines are temperature-sensitive, and storage and transport conditions must be documented continuously - not just spot-checked.
• Documentation: Everything from supplier qualification to deviation handling must be documented so it can be presented at a regulatory inspection.

Why fragmented systems are a risk

Many companies today handle GDP-related tasks across several separate systems - one for temperature logging, one for inventory management, and spreadsheets for documenting deviations. The problem with this approach is that data doesn’t automatically connect. When an authority asks for full documentation of a specific delivery, it requires manual compilation from multiple sources - which increases both the time spent and the risk of errors or gaps.

How a purpose-built ERP system supports compliance out of the box

An ERP system built for GDP from the ground up makes compliance an integrated part of daily workflows rather than a separate task. This includes:

• Automatic recording of temperature data linked directly to the products being stored or transported.
• Built-in audit trails that record who did what and when, without anyone needing to remember to document it manually.
• Automatic generation of the documentation that must be produced at an audit, instead of it having to be gathered together when the need arises.

The result is that compliance is no longer something that requires extra time - it arises as a natural part of the work that’s already being done.

This article is the first step along the way. In upcoming articles, we’ll dive into specific parts of GDP - temperature control, serialisation, audit preparation and risk management - each of which deserves its own in-depth look.
