II.21.6. Interim payments and payment of the balance 
The contractor (or leader in the case of a joint tender) must send an invoice for interim 
payment, as provided for in Article  I.6 or in the tender specifications or in the specific 
contract.  
The contractor (or leader in the case of a joint tender) must send an invoice for payment 
of the balance within 6 0 days of the end of the period of provision of the services, as 
provided for in Article I.6, in the tender specifications or in the specific contract.  
Payment of the invoice and approval of documents does not imply recognition of the 
regularity, authenticity, completeness and correctness of the declarations and information 
they contain.  
Payment of the balance may take the form of recovery.  
II.21.7. Suspension of the time allowed for payment 
The contracting authority may suspend the payment periods specified in Article I.6 at any 
time by notifying the contractor (or leader in the case of a joint tender) that its invoice 
cannot be processed. The reasons the contracting authority may cite for not being able to 
process an invoice are: 
(a) because it does not comply with the FWC;  
(b) because the contractor has not produced the appropriate documents or 
deliverables; or  
(c) because the contracting authority has observations on the documents or 
deliverables submitted with the invoice.  
The contracting authority must notify the contractor (or leader in the case of joint tender) 
as soon as possible of any such suspension, giving the reasons for it. In cases b) and c) 
referred above, the contracting authority shall notify the contractor (or leader in case of a 
joint tender) the time limits to submit additional information or corrections or a new version 
of the documents or deliverables if the contracting authority requires it.  
Suspension takes effect on the date the contracting authority sends the notification. The 
remaining payment period resumes from the date on which the requested information or 
revised documents are received or the necessary further verification, including on-the-spot 
checks, is carried out. Where the suspension period exceeds two months, the co ntractor 
(or leader in the case of a joint tender) may request the contracting authority to justify the 
continued suspension.  
Where the payment periods have been suspended following rejection of a document 
referred to in the first paragraph of this Article and the ne w document produced is also 
rejected, the contracting authority reserves the right to terminate the specific contract in 
accordance with Article II.18.1(c). 
II.21.8. Interest on late payment 
On expiry of the payment periods specified in Article I.6, the contractor (or leader in the 
case of a joint tender) is entitled to interest on late payment at the rate applied by the 
European Central Bank for its main refinancing operations in euros (the reference rate ) 
plus eight points. The reference rate is the rate in force, as published in the C series of the 
Official Journal of the European Union, on the first day of the month in which the payment 
period ends.
