What Simplified Cost Options Are
Simplified cost options (SCOs) are standard methodologies that let beneficiaries claim EU funding based on pre-agreed rates, lump sums, or flat rates — rather than tracking every actual euro spent.6 This cuts the administrative burden on both project teams and managing authorities.4
The European Commission provides technical guidance on SCOs for funds covered by Regulation (EU) 2021/1060, also known as the Common Provisions Regulation.7 This guidance applies to structural and investment funds across member states.1
The Three Main Simplified Cost Types
There are three types of SCOs you can use: unit costs, lump sums, and flat rates.4 Each applies to a different category of expenditure and is governed by specific eligibility rules.6
Unit costs cover a fixed price per measurable output — for example, a cost per participant or per training hour.6 Lump sums pay a set amount when a defined deliverable or result is achieved.4 Flat rates apply a fixed percentage to one eligible cost category to cover related costs, such as indirect costs.6
Legal Basis and Scope
The Commission notice on SCO guidelines extends a number of options that had previously been provided for in fund-specific regulations only to all ESI Funds.5 This wider scope gives managing authorities more flexibility in choosing which SCO type suits their programme.5
The guidelines provide technical guidance for colleagues and bodies involved in the monitoring, control, or audit of EU-funded operations.1 They are based on applicable EU law and are intended to support consistent implementation across member states.1
How to Apply SCOs in Practice
Start by identifying which cost categories in your project are eligible for SCOs.6 In the England ESF Operational Programme, SCOs are standard methodologies which can be used to calculate specific costs associated with ESF activities.6
Once your SCO type is chosen, document the methodology clearly. Only costs for personnel assigned to the action with properly documented time records can be considered eligible expenses. Weak documentation is the most common reason for cost rejections during audits.
For unit costs and lump sums, make sure outputs or results are measurable and verifiable.4 In accordance with the rules for application of corresponding unit costs, lump sums and flat rates applied under schemes for grants funded entirely by these rules, the approach must be traceable.4
Control and Audit Implications
SCOs shift the verification focus from receipts and invoices to achievement of outputs.3 Auditors will check whether the agreed conditions were met — not whether the money was spent on specific line items.3
This document expresses the views of Interact and does not commit to the European Commission, but its practical guidance on SCO verification reflects how control bodies approach the work.3 Prepare your project team to demonstrate outputs, not just expenditure.3
Common Mistakes to Avoid
Do not mix SCO and actual cost methods for the same cost category within the same operation.6 Choose one approach per cost type and apply it consistently throughout the project lifetime.4
Inadequate timesheet documentation can trigger cost rejections that ripple through your entire consortium budget. Even when using flat rates for indirect costs, personnel time records for direct costs must still be robust.
Many coordinators underestimate the setup work needed before SCOs can be applied. Define your unit costs and lump sum conditions precisely at the application stage — changes mid-project are difficult and can raise audit red flags.4
Budget-Friendly Tips
Flat rates are often the quickest SCO to implement for indirect costs because they require no separate tracking system — just a defined percentage applied to an eligible direct cost base.6 This alone can save significant staff time on financial reporting.6
If your programme already uses a recognised national or EU-level unit cost methodology, adopt it rather than building your own.5 The Commission's guidelines explicitly extend existing options across ESI Funds, so approved methodologies from one programme may already be transferable.5
Safety Warnings
SCOs do not eliminate audit risk — they change its nature.3 If the agreed output is not achieved, the entire lump sum or unit cost payment can be clawed back.3
Always check that your SCO methodology has received prior approval from the managing authority before incurring costs.1 Retroactive approval is rarely accepted and can render costs ineligible.1
Quick-Reference Checklist
- Identify eligible cost categories for SCOs in your project.6
- Select the right type: unit cost, lump sum, or flat rate.4
- Document the methodology clearly and get managing authority approval before starting.1
- Keep time records for all personnel on direct cost claims.
- Define measurable outputs or results for lump sums and unit costs.4
- Apply the chosen SCO type consistently — do not mix methods for the same category.6
- Prepare for audits by demonstrating outputs, not just expenditure.3
- Check whether an existing approved methodology can be reused across funds.5
