About fortnox integration
Here are the available types of setup for the fortnox integration, and which data is transferred between the systems.
Limitations
If somehing happens that prevents a daily voucher or invoice to be transferred this will be visible in Accounting Export page, read more here.
If you make manual changes to daily vouchers, invocies, credit invocies or correcting vouchers direclty in fortnox (which you normally should never do) make sure you know what you are doing as these changes will introduce a difference between the systems!
Golden rule if you use invoice export and payment import: Never change invoice amount, credit or void them in Fortnox, these changes should always be done in Nitesoft.
If you import payments; never add payments of invoices in Nitesoft, payment of invoice should always be done in Fortnox. Please note that only payments are imported from fortnox, so if you have comission, card fees etc. these should be registered as a payment also, read more here.
The only exception is if manual correction is needed for rounding errors or similar, read more about how to handle those special cases here.
If you do have to make a change to an invoice or credit invoice in fortnox directly you need to remember to make the same change to the correcting voucher of the invoice/credit invoice otherwise the revenue and VAT accounted will be incorrect.
