Synchronizing Customers and Suppliers

Create and synchronize customers and suppliers


  • Next or external application can be master
  • If OCR should be used for customer invoices, countrycode is mandatory
  • If reversed contractor VAT should be used on customer invoices, vatno is mandatory

How it works

A customer in Next can be both a customer and a supplier. To determine whether a customer is also a supplier, the field called isalsosupplier can be used

Customer numbers in Next can vary in length depending on how it is generated. If the customer number is:

  • generated by Next it will always have a fixed length of 6 digits with zero-filling, for example 001234, 001235.
  • entered manually by the user it will be saved according to the input without zero-filling, for example 1234, 1235

If the customer number is required to have a fixed length in an external system, the logic for this needs to be handled by the integration.

Synchronization of suppliers is mainly relevant for customers using the Procurement and/or Next E-invoice modules.

  • If Procurement is activated it is recommended that Next is master since suppliers must be created in Next
  • If Next E-invoice is activated it is recommended that Next is master. It is also recommended that E-invoice is activated before importing suppliers to Next to make sure that all suppliers are exported to the external scanning central that are handling the interpretation of incoming invoices.


Both customer and suppliers can have one or many contacts.

Contacts can be associated with a number of modules such as project, work order, variation order, procurement and customer invoice.

For the Swedish market the customer contacts and its related tables is also used for tax reduction administration.
