In Horizon Europe projects funded under the Lump Sum model, deliverables play a critical role in ensuring a smooth project execution. Unlike traditional cost-based projects, where funding requires detailed expense tracking, Lump Sum rules simplify the process by linking payments directly to completed work packages.

Deliverables are associated with work packages, and they serve as tangible results of the project to:

• Demonstrate progress – they show that specific stages of the project have been completed according to plan,
• Serve as documentation – these can be reports, prototypes, analyses – anything that proves a task has been completed,
• Support monitoring – the European Commission uses them to track if the project implementation is proceeding as expected (as the progress is assessed through results, not costs).

So, what does this mean for you? In general, deliverables play an indirect role – payments are based on the approval of work packages, but deliverables provide evidence that the work package has indeed been completed. If a deliverable is delayed or inadequate, payment for the work package may be reduced or withheld.

Best practices

Here’s the deal: since deliverables are key to demonstrating project progress and unlocking funding, ensuring high quality is essential. A well-structured approach to managing deliverables increases the likelihood of project success and reduces financial risk.

Here are some tips for preparing good quality deliverables:

• Define clear and realistic Deliverables plan

Ensure that deliverables are relevant, measurable and achievable. It is recommended at the Grant Agreement Preparation stage to review the plan included in the project proposal and introduce adjustments where needed (in agreement with the Project Officer) to confirm that the deliverables plan is reasonable and realistic. Make sure that the deliverables align with the work package objectives and the project impact goals.

• Start with a template

Prepare a standardized deliverable format to be used across all deliverables submitted within the project, ensuring consistency, clarity, and quality. It may include a cover page (project title and number, deliverable number, due date, authors), version history, executive summary, objectives, methodology, results, and conclusions. Moreover, it is recommended to use the corporate layout.

• Refer to the Description of Action in Annex 1

Each deliverable should be clearly linked to the duties included in the DoA. Describe exactly what was promised, avoid being vague – show clearly that you’ve delivered on a specific point from the plan. This helps to evidence compliance with the agreed scope and shows that the work promised has been addressed in practice.

• Use clear language

Use precise, objective wording and explain terminology where necessary. Where appropriate, include visuals such as graphs, images, tables or screenshots to effectively illustrate project progress and make the content easier to understand. If there are any supporting materials, include them as attachments to support the results.

• Perform an internal review

It is recommended to verify each deliverable against the agreed requirements, and confirm that the content is complete, clear, and aligned with the expected format before submission. Assign internal responsibility for drafting, reviewing, and finalizing the deliverable.

• Submit on time

Deliverables should be submitted by the agreed deadlines. If additional time is required to ensure the quality and completeness of a deliverable, the Project Officer (PO) should be informed in advance. Any delay should be clearly justified and agreed with the PO to maintain transparency and avoid issues during the review process.

Did you know that once you submit a deliverable, it cannot be overwritten or replaced? So make sure you are satisfied with the deliverable content before uploading it, as this is your final version and will be used for project evaluation.

Final tip: use AI tools with caution. While AI can be helpful in drafting and structuring deliverables, it should not replace expert input and careful review. Remember that the final responsibility for the content (including AI outputs) lies with you.

Conclusion

Deliverables in Horizon Europe Lump Sum projects are the central element of project implementation and financial justification. High quality deliverables are essential because they directly impact credibility, project success, and funding. In short, well-prepared deliverables drive successful and smooth Lump Sum project delivery.
