Is there a macOS version of MyInvoice?

Yes, the macOS version is available in the App Store and is included in the same subscription as the iOS version.

KSeF, business activity and property rental:

If a taxpayer runs a business under their NIP number and also rents out property as a private individual to a company, they must submit invoices to KSeF. KSeF does not allow separating these two activities, so MyInvoice cannot do this either. However, you can correctly issue invoices using a single account. To configure the app properly, add (if you haven’t already) one (or more) sellers as a business entity — you can optionally set a series number. Also add a second seller as a private individual and make sure to assign a session number, e.g. “RENT” (if you also use series for the business) or “RENT/” (if you don’t use series for the business). Go to Settings → Document Types and add {s} to the numbering format, e.g. for invoices INV/{s}{yyyy}/{i} (if you don’t use series for the business) or INV/{s}/{yyyy}/{i} (if you use series for the business). This way the business will get numbering like INV/2026/1, and the private individual will have separate numbering INV/RENT/2026/1. You may also need to assign expense documents to either the business or the private individual — to do this, open the expense invoice, long-press on the Buyer field (which is our Seller) and change the assignment to the correct seller.

Where is option X?

All application settings are located in the Settings menu. There you will find adding custom sellers, unit types, currencies, VAT rates, fiscal printer configuration (coming soon), etc.

Where is Dropbox synchronization?

Dropbox synchronization was removed in MyInvoice 3 in favor of iCloud.

VAT changes in 2014

One of the changes introduced in VAT regulations from January 2014 is the discontinuation of issuing Receipts in favor of Invoices for companies that are not VAT payers. Receipts imported from the previous version of the application are converted to basic Invoices.

PDF attachments are not visible when received by customers using MS Outlook and MS Outlook Express

The cause of this issue is the inability to display PDF attachments inline for messages sent in HTML format in those applications. Configure your iOS device to not send emails in HTML format — meaning do not use text formatting such as bold, active links, etc. Also check that your email signature does not contain HTML formatting. You can also force PDF files to be sent as compressed ZIP attachments.

What fiscal printers are supported?

MyInvoice works with Posnet fiscal printers using the Posnet protocol (the so-called new protocol), Novitus fiscal printers using the Novitus protocol and Novitus compatible with Posnet, and Elzab fiscal printers using the STX protocol. Compatibility tests were performed with the Posnet Thermal HD (Ethernet), Posnet Temo HS (WiFi and Bluetooth LE), Novitus HD E (Ethernet), and Elzab D10 (WiFi). You can also use other printers without an Ethernet port by means of an Ethernet-to-RS232 converter. Note: Posnet, Novitus, and Elzab printers equipped with Bluetooth 2.1 are not compatible with the Bluetooth available in iOS — only the Posnet Temo HS has a compatible Bluetooth LE module. On macOS, you can connect a printer via USB using RS232 emulation.

Which printers are supported?

The application works with all AirPrint™-compatible printers that support A4 printing.

My printer does not support AirPrint™. How can I print a document?

Some printer manufacturers provide dedicated iOS apps that allow printing over WiFi. To use such an app, select the document in MyInvoice you want to print and choose “Open in…”, then select the app designed for your printer. Software for leading printer manufacturers can be found here: Brother, Canon, HP, Xerox. You can also use the Printopia software to share AirPrint from your Mac.

What barcode scanners are supported?

The greatest capabilities come from SocketMobile scanners — on iOS you don’t need to activate the search fields. You can also use Bluetooth barcode scanners (with keyboard emulation) — simply pair the device with your Mac, iPhone, or iPad and use the scanner like an additional keyboard. Excellent results can also be achieved using the device’s built-in camera — however, you need to activate the scanner using a special barcode reader icon.

I am starting to use the application in the middle of the month. How can I set the starting number for a document?

If this is the first document of a given type (e.g. the first Invoice), the application will automatically ask for the number of the first document. The default will be 1.

How do I issue a Prepayment Invoice?

Prepayment Invoices are issued against an order. First create an Order, Proforma, or Estimate document. Tap on it to view its details, where you will find available actions. Tap Issue and the application will ask what type of document you want to create — select Prepayment Invoice.

How do I add a deposit to a Prepayment Invoice?

Find the most recently issued Prepayment Invoice for your contractor. Tap Add deposit.

How do I issue a Final Invoice for a Prepayment Invoice?

Find the most recently issued Prepayment Invoice for your contractor. Tap Add deposit and leave the default deposit amount — a deposit that covers all payments will automatically trigger the issuance of a Final Invoice.

I want to back up the database to my computer.

MyInvoice 3 does not create additional backups. Sync your data with iCloud to keep it safe. Also back up your entire device to iCloud.

I am issuing an EU invoice. How can I select the invoice language?

When your contractor is from a different country than the seller, the application automatically uses bilingual invoices if the contractor’s and seller’s languages differ. For example, if the seller is from Poland and the buyer is from another country, a bilingual invoice will be used with Polish as the primary language and English as the secondary. You can provide your own translations of document templates if you want a language other than English — such as Italian, German, or Spanish — to be used for your contractor. However, if the seller is in the UK and the buyer is in Ireland, a monolingual invoice will be used since both countries are English-speaking. You can also set the contractor’s language via Contractors → [Contractor] → Language.

I use a different document numbering format. How can I change it?

Go to the Settings tab, then Document Types. You can change the numbering format at any time. However, keep in mind that you should maintain consistent numbering throughout the entire year.

I want to export goods or services to EU countries. I need to provide a foreign currency bank account and enter the EU VAT number for the seller. How do I do that?

Simply add a new seller. Name it so you can distinguish it from your primary seller. Change the VAT number to your EU VAT number (with the PL prefix and without dashes). You can also enter a different IBAN bank account number there.

How do I import data from Maktura?

This feature has been removed from MyInvoice 3.

What data export and import formats are supported?
