Greek Business Tax Return Filings

I am based in Greece and I am planning to start a sole proprietorship providing remote bookkeeping services to UK and Irish businesses.

I am looking for a Greek accountant to support me with:

- Business setup in Greece (sole trader)
- VAT and VIES guidance for working with EU and non-EU clients
- Ongoing monthly accounting support (myDATA, tax filings, compliance)

My activity will be B2B services only (clients abroad), mainly bookkeeping and VAT support.

I want someone who:
- Has experience with freelancers / service-based businesses
- Understands cross-border transactions (EU & UK clients)
- Can advise on the correct VAT handling and invoicing

Please also let me know:
- The process for setting up the business
- Monthly accounting cost
- Any additional requirements I should be aware of

I am ready to start immediately.
