# How long must businesses keep delivery notes? Retention periods explained

Delivery note retention periods in Ireland depend on the role a document plays within a business. Unlike invoices, delivery notes do not generally have a separate retention period of their own. Instead, they are treated as **supporting business records** when they are needed to verify transactions, accounting entries or tax returns.

### Key Takeaways

Delivery note retention periods in Ireland depend on how a document is used:

- Delivery notes generally do not have a separate retention period of their own.
- A delivery note that supports accounting or tax records should generally be kept for six years.
- A delivery note without relevance for accounting or tax purposes generally has no specific retention period.
- The digital delivery note retention period is generally the same as for paper delivery notes.
- AI-based systems can help with classifying and archiving delivery notes.

There is no universal retention period that applies to every delivery note.

For tax purposes, businesses generally need to **keep relevant records for six years**. This can include delivery notes, depending on how they are used within the business process. Revenue requires businesses to retain records that support their tax returns and accounting records for this period.

## How long do businesses need to keep delivery notes in Ireland?

The delivery note retention period depends on whether the document is needed as part of the company’s records.

Delivery notes may be relevant, for example, when they:

- confirm that goods were delivered or received,
- support purchase or sales records,
- provide evidence for accounting entries,
- help explain transactions during a Revenue audit.

If a delivery note forms part of these records, businesses should generally keep it for six years. This applies to both received and issued delivery notes where they are relevant to the company’s accounting or tax obligations.

There is therefore no universal retention period for commercial delivery notes that applies to every document. Businesses should assess whether a delivery note forms part of their required records.

### Why should businesses keep delivery notes?

Delivery notes can help businesses prove that goods were supplied or received. They are particularly **useful when checking invoices, resolving disputes or explaining transactions during an audit**. A delivery note may contain important information such as supplier or customer details, delivery date, description and quantity of goods, references to purchase orders or invoices.

Keeping these documents together with related invoices and accounting records can make financial processes easier to track.

## What is the retention period for paper delivery notes?

Paper delivery notes that form part of a business’s required accounting or tax records should generally be kept for six years. Businesses must keep records that **allow Revenue to verify the information** included in tax returns. These records can include documents linked to purchases, sales and accounting processes. Companies also have accounting record obligations under the [Companies Act 2014](https://www.irishstatutebook.ie/eli/2014/act/38/enacted/en/html "Companies Act 2014"). Accounting records must generally be preserved for at least six years after the end of the financial year to which they relate.

Businesses should therefore ensure that delivery notes are complete, easy to locate, linked to the relevant transaction, protected against loss or unauthorised changes.

## What is the retention period for digital delivery notes?

The digital delivery note retention period is generally the same as for paper delivery notes. The important factor is not the format, but **whether the electronic document remains a reliable business record**.

When storing delivery notes digitally, businesses should ensure that:

- documents remain readable throughout the retention period,
- records can be accessed when required,
- files are protected against unauthorised changes,
- documents can be linked to the relevant transaction.

Electronic records must remain available if Revenue requests access to business records. Simply saving delivery notes in an unstructured email inbox or random folders may make it difficult to demonstrate proper record keeping.

## How should businesses store delivery notes?

Many businesses receive large numbers of delivery notes, especially when dealing with regular suppliers. A **structured document management system** can help with storing delivery notes and finding them when needed.

Useful practices include:

- storing delivery notes together with related invoices,
- using consistent file names,
- organising documents by supplier, date or project,
- backing up digital records regularly.

Automated document management systems can also help extract information from delivery notes and assign documents to the correct transaction.

## How can AI help with archiving delivery notes?

Manually reviewing large numbers of delivery notes can be time-consuming, particularly for small and medium-sized enterprises (SMEs). Businesses may not always have the resources to check each document individually to determine whether it forms part of their required accounting or tax records and which retention period applies.

AI-based systems can help automate this process. Specialised document management systems can extract information from delivery notes, classify documents and apply predefined retention rules. Systems that use tamper-resistant storage, such as WORM (Write Once, Read Many) archives, can also help protect archived documents against subsequent changes and support businesses with their digital record-keeping processes.

For example, an SME that receives numerous delivery notes each day could use a specialised AI system as follows:

1. A new delivery note is automatically detected in the archive and its contents are extracted.
2. The AI system analyses information such as the supplier, goods, quantities, invoice references and relevant accounting information.
3. The system classifies the document according to predefined document types.
4. Based on predefined rules, the system can then suggest an appropriate retention period or apply one automatically and archive the document accordingly.

Automation like this can be particularly useful for SMEs, as record-keeping requirements and internal retention rules can change. A digital archive with predefined compliance rules can help make archiving processes more efficient. However, responsibility for complying with the applicable legal and tax requirements remains with the business.

## What happens if businesses do not keep delivery notes?

If businesses cannot provide supporting records during a Revenue inspection, they may have difficulties proving that transactions were recorded correctly. Revenue specifically lists **delivery notes as documents that can support sales records**.

Failure to comply with statutory record-keeping requirements can also result in a **penalty of €3,000** under Section 886 of the Taxes Consolidation Act 1997. This does not mean that every missing delivery note automatically results in a €3,000 penalty. Rather, the penalty can apply where a business fails to keep the records or supporting documents it is legally required to retain.

Businesses should therefore regularly check which delivery notes need to be retained, whether documents are stored securely and whether records can be found quickly when required. A clear process for keeping delivery notes helps businesses meet record-keeping requirements and maintain reliable accounting documentation.
