Connecting Elorus — invoicing without retyping

The job is done, the amounts are on the quote, and now somebody retypes them into another program to raise an invoice. That retyping is what the Elorus connection removes.

Connecting

Settings → Integrations → Elorus. You need two things from your Elorus account:

  • API Key
  • Organization ID

(The Organization Slug is optional.) Hit Connect to Elorus and PressCal confirms straight away that it's talking to your account.

Disconnecting is harmless: invoices already issued are unaffected — they live in Elorus, not here.

Invoice defaults

Once connected, you set once what gets used on every new document:

  • Document type and VAT
  • Units of measure

In Greece the myDATA fields are added too: document type (1.1 Sales Invoice, 2.1 Services, 5.1 Credit Note, 11.1/11.2 Receipts), classification category and type (revenue from merchandise / products / services, wholesale, intra-community…).

The Refresh button pulls the lists from Elorus again — useful when you add a new type or unit over there.

Outside Greece

Elorus isn't only for Greek print shops. If your organisation's country supports it, the tab appears as normal — without the myDATA/AADE fields, which are purely Greek tax matters. The document's currency and country come from your organisation.

The invoice

You raise it on the quote, with one button. Customer, lines and amounts carry over as they are; you type nothing a second time.

In Greece, if you've also set up the AADE VAT-number lookup (it needs your myAADE username/password and your own VAT number), the contact is found or created with official registry details — right legal name, right tax office, no typos that come back to haunt you.

Which way each thing syncs — mind the direction

Not everything is two-way, and it's worth knowing:

  • Catalogue products: both directions. You can import your whole catalogue from Elorus, or push your own products over there (all of them, or only the new ones).
  • Contacts: PressCal → Elorus only. Your customers go over to Elorus when invoicing needs them. Elorus contacts do not come down into PressCal automatically.

So: the clean customer list is built here and travels there, while the product catalogue can start from whichever side you already have it written on.

Where things live

The Elorus product catalogue lives in Inventory, not in Settings. Which makes sense: it's stock and a price list, not a parameter. Settings keeps only the connection and the document defaults.
