FAQ
Do I need a sevDesk developer account? No. You use the API token of your own sevDesk user.
Is there a test system? sevDesk has no sandbox. Use a free sevDesk trial account and its token in Test mode.
Who numbers the invoices? sevDesk, when the invoice is finalized.
Can an invoice be created twice? The add-on is built to prevent it: it records every attempt before it calls sevDesk and looks the invoice up after a lost answer. If it still cannot tell, it stops and asks you instead of sending again; only your “Issue now” creates it then.
E-invoices (XRechnung / ZUGFeRD)? Not created by version 1.0.0: sevDesk needs extra buyer and payment data for them that the add-on does not send yet. Turn an invoice into an e-invoice in sevDesk if needed.
Which tax rules are used? See Developer notes > Tax rules. Domestic reverse charge (§13b) and §4 exemptions are not chosen automatically.
Does it book payments? Yes, on a clearing or cash account you choose. Bank accounts in sevDesk need real bank transactions, so they cannot be used.
Does it work with bookkeeping version 1.0? sevDesk retired it in 2024; the add-on still sends the old tax types (default, eu, noteu, ss) if an account reports 1.0, but this legacy path is not a supported feature.
Foreign currencies? The invoice uses the shop’s primary currency.
Is this GoBD compliant / certified? The add-on transfers data to sevDesk; it makes no compliance claim. sevDesk and your tax adviser are responsible for your bookkeeping.
What happens on uninstall? Order links, contact map, connection and settings are kept unless you tick “Permanently delete all invoice data on uninstall”.
My license shows “Pending verification”
Section titled “My license shows “Pending verification””This status appears in older add-on versions when you use a CS-Cart Marketplace license number that our license server has not matched with the Marketplace yet. The add-on is fully working in this state: no feature is switched off and you do not need to do anything. Newer versions show it as Active (Marketplace license). We confirm Marketplace numbers on our side; click Check now on the add-on’s License tab (Add-ons → Manage add-ons → the add-on) a little later and it shows Active. If it has not changed after 24 hours, contact support with your Marketplace order number.
Still stuck?
Section titled “Still stuck?”Work through the troubleshooting guide, then contact support with your CS-Cart version, edition, PHP version and the add-on version (1.0.0).
