1.To issue an invoice to a customer from the POS, you need to go to the Receipts section, then follow these steps:
2.Choose one of the options: Send the invoice by e-mail or Print the invoice.
3. If you choose to print the invoice, you will need to select the customer for whom the invoice
If the customer already exists in your database in the Clients section, you just need to search for them by name, tax ID, or phone number and select them from the list.
When you choose to send the invoice by e-mail, once the customer is selected, a window will appear where you can send the invoice via e-mail. You will need to enter the customer’s e-mail address, then click Save.
If you choose to print the invoice, you only need to select the customer.
If the customer does not exist, you will need to create them using the + Add new client button on the middle side of the window.
Edge cases
I can no longer find the receipt in POS to send the invoice
The POS only displays receipts from the last 6 days. For an older receipt, issue or send the invoice from the admin account:
Go to the Sales menu in admin.
Search for the receipt using the magnifier — you can filter by date and by payment method.
Open the order (3 dots → View) and issue / send the invoice.
Note: a modern payment on a Z report represents a bank transfer. If the receipt is not older than 6 days, you can also find it in POS → Receipts, filtering by payment method.
I Can't Select the Customer — It Asks for Write Permission
There are two possible causes; check them in this order:
First: Does the account have a main package installed (Pro, Premium, or Titanium)? Without a main package, paid modules — including Invoicing and Customers — are not installed on the account, so no user has permissions for them, not even the administrator. The block appears as a permissions-related message. This can be resolved by installing a package from the Marketplace.
Second: If you already have a main package installed, then it is indeed a user permission issue. An administrator needs to give you Write permission for the Customers app, for the location you are working with, from Account Settings → Users (or from the assigned role). You then need to log out and log back in. See the article “I Can’t Find an App in My Account (Even Though It Is Installed)” for more details.
What Appears on the Invoice Printed from POS?
On the invoice printed from POS, the “Receipt No.” line shows the fiscal receipt number followed, in parentheses, by the date and time when the receipt was issued — for example: Receipt No.: 13 (16/07/2026 00:15). The date is the date the receipt was issued, based on the local time of the location. Therefore, for a receipt printed after midnight, the invoice shows the printing date, not the date when the order was opened.
If no fiscal receipt was issued for the order, the date in parentheses does not appear.
If your company is not VAT registered (the “Exempt without the right to deduct VAT, according to Art. 310” option is checked under Account Settings → Company Settings → Invoice Settings), the seller’s CUI is printed on this invoice without the “RO” prefix.
Which printer is the invoice printed on?
If a non-fiscal thermal printer is installed at the location (Star, Epson, Posiflex, Sam4S or Citizen — the brands listed in the “Compatible Equipment” article), the invoice is printed directly from the POS app, on the same printer used for the order receipt and payment note. You do not need to download a PDF or use a computer.
The invoice is printed on the non-fiscal printer set as Default at the location. The invoice is not routed through the printing rules: it does not depend on product tags or on the rooms selected for the printer, so there is nothing to configure in “Print Rule Configuration” for invoices to be printed.
If the location does not have any non-fiscal printer installed, the app displays the message “No printer found.” under the “Print Invoice” heading. In this case, the cause is the missing printer, not the network — first install the printer by following the steps in the “How do I install a non-fiscal printer? [Ebriza POS NEXT]” article.
The invoice can also be obtained in PDF format if you do not have a non-fiscal printer or if you want it on A4 paper: from the admin account, go to the Sales menu, open the order, and select Download Invoice. This is an alternative, not the only option.
I need to change the buyer on a closed receipt before issuing the invoice
If the wrong buyer is on a closed receipt, you can correct it straight from
the Receipt Actions menu, as long as you have not issued the invoice yet.
Important: the options appear only when the receipt already has a client
assigned and has no invoice. If an invoice has already been issued, you need to cancel it and re-issue it with the correct buyer.
Steps:
Go to the Receipts section and long-press the receipt (or open the receipt and tap the Receipt Actions button in the top-right corner).
Choose one of the options:
Update client details - edits the details of the client already linked to the receipt (name, VAT ID, address, etc.). You will be asked to confirm, because this option changes the client record, not just the receipt.
Replace with another client - links a different client to the receipt. No client record is modified.
What changes and what does not:
Receipts and invoices that were already issued keep the details they were
issued with - your history is not rewritten. Update client details changes the
client record going forward (in the Clients app, on your other devices and on
future orders) and updates the current receipt, so the invoice you issue from
it shows the corrected details.
If you only want to change the buyer on this one receipt without touching any client record, use Replace with another client.
Note: the POS only shows receipts from the last 6 days. For an older receipt, correct the buyer from the admin account, in the Sales menu.
