An MS-Logic product
LogicInvoice
The smart invoicing system
One month, no commitment. We help you get started.
Electronic invoicing in full compliance with AADE’s myDATA, with smart checks that guide you at every step. You issue documents from anywhere, with nothing to install, and they are transmitted automatically through a certified e-Invoicing Provider.
It replaces the cash register and the fiscal device (FIMAS), with no extra hardware to buy. Every document carries the AADE marks (MARK, UID, QR).
Smart, not merely electronic
Smart checks in real time
LogicInvoice does not wait for you to make a mistake. It tells you what is missing from the document, what ought to be there, watches your transactions and warns you if something looks odd, before issuing.
Smart assistant
Give an instruction ("invoice X as usual") or upload a photo of an invoice or a handwritten order, and the assistant prepares the draft. It also answers questions like "who owes me" or "how much VAT did I issue this quarter". It always prepares a draft; the issuing is yours. It runs on units, shared across the whole MS-Logic ecosystem.
See the assistant in under a minute
Two short videos, with real LogicInvoice screens. Greek voice-over, English subtitles.
The client orders over the phone, you write it on a piece of paper. A photo to the assistant, and the draft is ready with client, items, VAT and payment method.
No paper. One sentence in your own words, the way you would say it to your accountant, and the assistant prepares the same draft.
The videos are hosted on our own server and load only when you press play. No external player, no cookies.
Assistant units, shared across the ecosystem
The assistant runs on units, and your balance is one balance for all of MS-Logic. Whatever units you have, you spend them where you want: today in LogicInvoice, tomorrow in Ekkremés, the day after in MS-Finance. One account, one balance.
20 monthly units
Every LogicInvoice subscription gives 20 units a month, renewed automatically. They are valid within the month and do not carry over to the next.
Purchased units
If you need more, the extra packs never expire. They stay in your balance until you use them, in whichever app you like.
Your balance is always visible: how many monthly, how many purchased, when they renew. The e-Invoicing Provider’s units are an entirely separate thing and concern the transmission of documents to AADE.
Every myDATA document type
Sales and service invoices, retail receipts, credit notes, delivery notes, acquisition titles. Issued and transmitted with MARK and QR code, through a certified e-Invoicing Provider.
A dashboard that means something
The home screen shows turnover, collections, the quarter’s VAT and who owes you, with the day’s priorities and quick-issue buttons.
Clients, suppliers and items
A complete client book, goods, services and fixed assets, subscription services and composite items, all in one place.
Cash and collections
Receipts and payments, settlement per invoice, bank transaction matching and automatic reminders to debtors.
Client portal
Every document gets a secure link with QR code and MARK, payment status, PDF, exports for the accountant and an EL/EN language switch.
Online payments
The client pays by card or in instalments (Stripe and Viva), by IRIS, or by bank transfer with a SEPA QR code. Collections are recorded automatically.
Statements and reports
Account cards, balances, receivables ageing and subscriptions, for a clear picture of the business.
Digital Client Registry
An add-on for car repair shops and businesses of the vehicle sector: the records go to AADE from inside LogicInvoice, without the AADE website.
No cash register, no fiscal device
It replaces the fiscal device (FIMAS) with no extra hardware to buy, with built-in POS connection.
On your phone, like an app
LogicInvoice installs on the home screen of your phone or computer and opens like a normal app, with no address bar. No app store, and no second version to keep updated: it is the same app, always in its latest form. Useful when invoicing catches you standing up, at the client’s premises.
Personal, local support
MS-Logic at your side, with a person who knows your business. Not faceless, mass-market SaaS.
Plans and prices
Annual subscription. Choose the plan that fits your business.
1 month free trial, no commitment
Extra users (Pro only): €30 per user or €120 per 5 users per year, excl. VAT. The cheapest combination is applied automatically.
The Provider’s units, the cost the plans do not show
Every document sent to myDATA passes through a certified e-Invoicing Provider and consumes units. By law the units are issued to your own tax number, so you pay for them, separately from the subscription. You buy them in a few clicks from inside LogicInvoice.
Their cost is set by the provider's price list.
The Provider’s units have nothing to do with the assistant’s units, which are included in the plans.
Add-ons
Vehicle logging in AADE’s Digital Client Registry, with the invoice MARK linked automatically. For vehicle workshops, and soon for car washes, car parks and rentals. An add-on with its own annual subscription, activated from inside the app.

Do I lose data if I don't renew extra users?
