What Is eInvoice as a Service?
Advintek’s eInvoice as a Service is a done-for-you compliance solution built for Greek businesses that need to meet AADE myDATA obligations without building internal teams or learning technical frameworks.
Perfect for SMEs, legal professionals, retailers, and enterprises who’d rather stay focused on their business than on invoice regulations. Hand the entire eInvoicing lifecycle to Advintek and your team gets back its time — errors go down, records stay audit-clean, and the AADE portal never needs to be opened.
No portals. No paperwork. No risk. Just results.
How It Works – Simple 3-Step Process
Advintek’s e-Invoice as a Service is designed to be as effortless as possible. No need to log into the Greece or rely on third-party agents. Here’s how it works:
Send Us Your Invoice Data
Drop your invoice details to Advintek — email, secure upload, or direct integration, whichever suits your workflow. No special formatting or manual prep work needed from your side.
We Validate, Map, and Submit
Our Invoice Factory system takes your data, checks every field for accuracy, maps it to AADE myDATA format, and submits it securely — VAT fields, metadata, and all required Greek tax details included.
You Get Confirmation and Archive Access
Submission done, you receive real-time status updates on each invoice. Every record is then securely archived for 10 years, keeping you fully covered under Greek regulatory retention requirements.
