We offer great flexibility, allowing you to customize many details of your generated documents. Let us know via chat if you need any additional features—we're happy to help! 😊
✅ Default document language
We aim to automatically select the language based on the customer's billing country.
Example
Let's say that the country on the customer billing address is Poland, so the app tries to create the document in Polish, but if there is not Polish option in SuperFaktúra, the app uses your default value when generating, which is Czech:
✅ Unit
Any text entered here will appear on the document for each item. If left blank, no unit name will be included on the invoice.
Example
If you enter "PC" on the app dashboard:
Within SuperFaktúra you will see this unit name at every document item:
✅ Comment
This text will be shown in the comment section of your created document as an internal comment, so your customer will not see this. You can use this merge tags: {{order_number}}, {{order_id}}
Example
If you enter 'Shopify order number is {{order_number}}' on the app dashboard:
Within SuperFaktúra you will see this:
✅ Numbering sequences
By default we use your SuperFaktúra default numbering sequence, but you can override that by choosing another option here. Edit the list items within SuperFaktúra > Settings > Application > Classifiers
Click 'Refresh list now' button to see the latest list from SuperFaktúra settings. If you do not see the list, try to refresh again, wait a little and you will see the list.
Extra feature for 'Invoice':
If you choose 'Use the shipping address based method' »
Example
First, within SuperFaktúra, manage your numbering sequences and Save them:
On the app dashboard, click 'Refresh list now' and choose this numbering sequence:
Within SuperFaktúra you will see this, documents are numbered based on your settings:
🔄 To sync your document numbering with your Shopify order number:
Check, which is your next Shopify order number, for example '1012'
Go to SuperFaktúra » Settings » Application » Classifiers
Write CCCC tag into that format – it means that your will use an automatically increasing number in your document numbering.
Then set your 'Next number' to '1012' – so your numbering (your CCCC value) will start from '1012'
Save settings here.
Optional but recommended: Using the "When any order is created" trigger, you minimize this risk and maintain the correct sequence – so select this trigger in your app dashboard and save settings.
This is the only thing we can recommend, since the document numbering is chronological and the Shopify numbering (Shopify order number) is a separate numbering logic.
✅ Variable symbol
Choose a variable symbol to be included on your document. It will be shown on the generated document.
If you choose 'None', your variable symbol field will be empty.
If you choose 'Order number', it will be shown on your SuperFaktúra document (e.g: 1019)
If you choose 'Order ID', it will be shown on your SuperFaktúra document (e.g: #001234)
Don’t use letters as prefixes or suffixes in your Order ID, as SuperFaktúra won’t accept them. Use numbers instead (e.g., ‘00’ instead of ‘ZZ’).
Difference between Order number and Order ID
✅ ‘Order No. invoice field
You can select what should be in the Order No. field on the created SuperFaktúra documents. You can transfer Order ID and Order Number to SuperFaktúra (not the same, there is a little difference, explained below)
Example
If you choose 'Order ID' here on the app dashboard:
It will be shown on the generated documents in SuperFaktúra here:
Differences?
Order Number
It is the numbering that Shopify generates automatically
Example 1234
Order ID
It is the ID that Shopify generates automatically. You can add PREFIX and SUFFIX, and between them, there is Order Number.
Format: PREFIX + Order Number + SUFFIX
Example: BB1234HELLO
You can edit that within Shopify Admin » Settings » General » Order ID section
✅ Custom email address on documents
You can customize the email address displayed on your generated documents. If no email address is provided, the default SuperFaktúra email address will be used.
Example
If you enter "demo@email.com" on the app dashboard:
You will see see this custom email address on the created documents:
ℹ️ Additionals
Content parameters not listed above – that you can't configure on your dashboard – work like this:
Tax logic
Please note that our app always works based on your Shopify order data, your Shopify tax settings, and the invoicing system settings.
The exact configuration of Shopify and your invoicing system (e.g. VAT rules, OSS, exemptions, etc.) can be very specific to your business and country. For this reason, we strongly recommend involving a tax advisor or accountant to make sure everything is set up correctly and fully compliant.
OSS logic
On the SuperFaktúra document, OSS mode is shown in the document details. OSS applies when all of these conditions are met:
Shopify order conditions
The order is B2C.
The order fulfillment location country is different from the order shipping address country.
The shipping address country is in the EU.
SuperFaktúra condition
The customer VAT number field must be empty.
Important: if an invalid VAT number is entered in Shopify, it can still be forwarded.
App condition
There is no separate app condition for OSS in SuperFaktúra.
OSS limitation: If the OSS conditions are true, the app marks the document as OSS. This means the document can receive the OSS label whenever the condition matches.
Reverse Charge logic
On the SuperFaktúra document, Reverse Charge text is shown. This text is generated by the app based on the document language, not directly by SuperFaktúra.
Reverse Charge applies when all of these Shopify order conditions are met:
The order is B2B.
The order fulfillment location country is different from the order shipping address country.
The shipping address country is in the EU.
The Shopify customer has this tax exemption: Customer → Tax details → Tax exemptions → Reverse Charge (EU/UK).
B2C and B2B logic
B2C: there is no value in the customer VAT number field.
B2B: there is a value in the customer VAT number field.
Order tax exempt
In Shopify, this is controlled on order level:
Payment → Charge taxes → Uncheck
If the Shopify order is tax exempt, all items on the iDoklad document use VAT rate 0.
Product tax exempt
In Shopify, this is controlled on product level:
Product → Price → Charge tax on this product → Uncheck
If a product is tax exempt, that product line uses VAT rate 0 on the iDoklad document.
Customer tax exempt
In Shopify, this is controlled on customer level:
Customer → Tax details → Don’t collect tax → Check
If the customer is tax exempt, all items on the iDoklad document use VAT rate 0.
Discounts
Discounts are based on Shopify order data.
The discount name on the document is:
the discount title, if available otherwise the discount cod
If more than one discount is applied to the same item, for example item-level and order-level discounts, the discount names are shown separated by commas.
Discounts » Free shipping
For free shipping, the app creates a new item on the document with the original shipping fee as a negative amount.
Discounts » % or fixed amount discounts
If a percentage or fixed amount discount is added at item level or order level, it appears as a new item with a negative amount.
Shipping address on the document
The shipping address is shown on the SuperFaktúra document.
Currency
The document is created in the Shopify order presentment currency.
This means the app uses the currency the customer used at checkout.
Paid status syncing
If a Shopify order is created as paid, or later updated to paid, the related document in SuperFaktúra is also marked as paid.
This works in one direction only:
Shopify → SuperFaktúra
It does not work in the opposite direction:
SuperFaktúra → Shopify
So if you mark a document as paid in SuperFaktúra, the Shopify order will not be updated by the app.
Dates
Issue date:
The issue date is the day the document is created.
Delivery date:
For SuperFaktúra, this is the same as the issue date.
Due date:
The due date comes from the value set in SuperFaktúra.
Dates on Credit notes:
Issue date: the day the credit note is created
Delivery date: the day the credit note is created
Due date: comes from the value set in SuperFaktúra
Document template
You can create template variants in SuperFaktúra.
The app uses the selected / available SuperFaktúra template variant when creating the document.
Email template
Email text can be configured in SuperFaktúra.
Payment method
The app reads the payment method from the Shopify order and tries to match it with an available SuperFaktúra payment method.
If the app cannot match it, it uses the default value.
For SuperFaktúra, the default payment method is set by the user.
Contact database behavior
SuperFaktúra has a Contact database.
The app sends Shopify order data to SuperFaktúra.
If required billing data is missing from the Billing address, the app uses the available Shopify Customer data instead.
After the data is sent, SuperFaktúra manages the Contact database automatically.
POS orders without customer data
If there is no customer data, the app creates a document only for POS orders.
If no Contact name is available, the app uses the email address as the Contact name.
If there is no email address either, the app uses Shopify POS as the Contact name.
