Can a consulting agreement be signed electronically?
Yes. A consulting agreement is an ordinary contract with no form requirement, and the eIDAS regulation (910/2014) states in article 25.1 that an electronic signature may not be denied legal effect solely on the grounds that it is in electronic form.
Assignments often start before the paperwork does. The consultant is booked, the project is burning, and the contract can follow later. That works until someone leaves, the manager changes, or an invoice is questioned.
With a link, signing takes minutes instead of days, and the argument about which version applies never starts.
What should the consulting agreement settle before the work starts?
Scope, fee, payment terms, rights to the result and confidentiality. Those are the five points that otherwise turn into a dispute.
Write out what is included and what counts as additional work. State the fee per hour or per delivery, and who pays for travel and subcontractors.
Rights to what gets produced belong on paper, because the default position is rarely the one people assume. If the consultant will see source code, customer data or calculations, confidentiality belongs in an NDA signed first.
