GSIS-Compliant E-Invoice Issuance – One-Time Assignment

Job ID: 40108266

Budget: ₹12,500 – ₹37,500 INR

I need a Greece-based accountant or compliance specialist to help me issue and file a single GSIS / myDATA electronic invoice for a service transaction. This invoice must follow custom requirements, including client identification codes, project and task descriptions, and any compliance-related notes or references that the platform expects.

Here’s what I’m looking for you to handle from start to finish:

• Review the service transaction against current GSIS / myDATA rules and confirm the exact codes and fields that apply.
• Advise me on the most cost-effective route to stay fully compliant—whether that means using a certified provider, issuing through my own accounting software, or another approved method.
• Prepare and submit the e-invoice inside the GSIS / myDATA environment, making sure every custom field (ID codes, project details, compliance notes) is correctly populated.
• Provide confirmation that the submission was accepted without errors and that the invoice is now legally valid.

This is a one-time, non-recurring task. Clear English communication is essential so we can move quickly. When you reply, please outline similar GSIS / myDATA e-invoicing projects you have completed, the tool or gateway you plan to use, your estimated turnaround time, and your fee.
