Technical contractors
The invoice and the card payment, where the job is done.
Air conditioning, electrical work, maintenance: the job is done at the customer’s home, shop or boat, but the document is usually issued at the office. With LogicInvoice it is issued on site, from a mobile phone, and the customer pays by card the same minute.
What a technical contractor has to do today
Electronic invoicing
For invoices to businesses, through a certified provider, now for every business: from 02/03/2026 for turnover above 1 million euros, from 01/10/2026 for all others, with a transition period until 31/12/2026.
A connected POS
A card terminal can no longer work on its own. It must be connected either to a cash register or fiscal device or to invoicing software connected to a provider, such as LogicInvoice.
Households and businesses
The same company works in homes and in businesses, so it issues both retail receipts and invoices. Both have to come from the same place, with the same card terminal.
A technical contractor, before and after
Real cases from our clients.
Before
Documents from the office
- A program with a fiscal device (ΦΗΜΑΣ), or a cash register.
- Documents were issued in advance, at the office, and the technician took them along.
The card terminal was connected to the fiscal device or the cash register, so it only accepted cards on a retail receipt. When a business customer wanted to pay by card and get an invoice, a retail receipt had to be issued so the card could go through, then cancelled, and finally the invoice issued on credit.
The other workaround was a second card terminal just for invoices, at the same bank. Two terminals for the same payments.
Two documents and one cancellation for one payment.
After
One app for everything
- Receipts and invoices come out of LogicInvoice.
- The app works from a mobile phone, and the card terminal connects to it.
- The document is issued at the customer’s premises, when the job is finished.
The customer, private or business, pays by card and gets a receipt or invoice straight away. Nothing needs to be prepared in advance.
One document, where the work was done.
Cash register or fiscal device: the same problem
They are two different things that do the same job. With a cash register the receipt is issued directly by the machine. With a fiscal device (ΦΗΜΑΣ) it is issued from a program, and the device adds the tax signature. Whichever of the two a business has, the card terminal is connected to it, and so locked to retail. LogicInvoice does the job of both, and the card terminal connects to it, for retail and for invoices.

Frequently asked questions
Can I issue a document at the customer’s premises?
Yes. LogicInvoice works from a mobile phone, and the card terminal connects to it. The technician issues a receipt or an invoice where the work was done, and the customer pays by card straight away.
Can I invoice a business that pays by card?
Yes. When the card terminal is connected to LogicInvoice, it works for invoices too, not only for retail receipts. One document, no cancellations.
What happens to the cash register or fiscal device I have?
You can retire it, whichever of the two you have. LogicInvoice does their job, so you need neither a cash register nor a fiscal device, not even for retail receipts.
Can I keep a second card terminal just for invoices?
You can, and it was the other common workaround: one terminal locked to retail and a second one, at the same bank, for invoices. With LogicInvoice it is not needed: one terminal does both.
Does it work with my bank’s card terminal?
The connection works with the usual retail card terminals from many banks, and so far we have not come across a problem with any of them. Tell us which one you have and we will confirm it before you start.
When does electronic invoicing become mandatory?
It already applies. For businesses with turnover above 1 million euros from 02/03/2026, for all others from 01/10/2026, with a transition period until 31/12/2026.
What does it cost?
The LogicInvoice subscription and the certified provider’s units, which are paid separately as with any electronic invoicing software. Prices are on the LogicInvoice page and in the e-shop.
