ECHA/2020/666  Annex 1 to Tender Specifications  Technical Specifications Restricted  74 (77) As a rule, payments for recurrent services (e.g. application management services) and  Time & Means contracts will be carried out on a monthly or quarterly basis (as specified in  each specific contract). For contracts creating an obligation for the Contractor to provide  deliverables (e.g. projects), the payment schedule, based on prior acceptance of  deliverables by the Agency, will be defined in the specific contract. Requests for payment  shall be admissible only when they are based on an invoice made in good and due form  for services accepted by the Agency. Each invoice must include a detailed list of services  covered by the invoice.  ECHA reserves the right to pay less than the amount foreseen in the specific contracts in  accordance with the services actually rendered by the Contractor.  Where foreseen by the relevant specific contract, expenditure incurred at the request of  the Agency for travels outside the normal place of performance of the contract, will be  reimbursed in accordance with Articles I.5.3 and II.22 of the draft Framework Contract.  As a rule, under this Framework Contract paper invoices will not be required. Payments  will be based on scanned invoices sent by the Contractor to ECHA via e-mail. However, if  requested by ECHA, the Contractor shall send paper invoices to the Agency at no additional  cost for ECHA.  Potentially in the future, upon request by ECHA, the Contractor shall make invoices  available to the Agency in a common and structured electronic format, as agreed between  ECHA and the Contractor, suitable for automated processing (for example, ECHA has  already implemented  the European Commission’s e -Procurement platform for e-invoicing  under a number of framework contracts). The introduction of such system into the  Framework Contract shall be agreed by the parties at governance level. See section 6.2.2  for further details.  In the context of the implementation of a specific contract a performance guarantee may  be required by the Agency (Article I.6.4 of the draft Framework Contract), in order to  ensure compliance with contractual obligations in the case of complex or critical services,  in particular, the FWC666 phase-in and phase-out for Lot 2. The Agency may also  alternatively apply a retention money guarantee (Article I.6.5 of the draft Framework  Contract).  Furthermore, the Agency refers to the requirements for the contractor regarding the  insurance of its liability (e.g. professional risk indemnity insurance), as laid down in Article  I.18 of the draft FWC666. The contractor shall be insured, either through an already  existing insurance, or an insurance taken specifically for this Framework Contract, in order  to cover liability, which he could incur during the implementation of the Framework  Contract.  Where the Framework Contract requires the processing of personal data, the contractor  may act only under the supervision of the data controller, in particular with regard to the  purposes of the processing, the categories of data which may be processed, the recipients  of the data, and the means by which the data subject may exercise his/her rights.  The data shall be confidential within the meaning of Regulation (EU) 2018/1725 on the  protection of natural persons with regard to the processing of personal data by Union  institutions, bodies, offices and agencies and on the free movement of such data. The  contractor shall limit access to the data to the staff strictly necessary for the performance,  management and monitoring of the Contract.  The contractor undertakes to adopt appropriate technical and organisational security  P.O. Box 400, FI-00121 Helsinki, Finland | Tel. +358 9 686180 | echa.europa.eu  9.6.
