How does the SnelStart integration work?

SnelStart is one of the accounting software packages that Robaws has a direct integration with.
Thanks to the API integration between Robaws and SnelStart, these packages work together seamlessly.
You can prepare your entire bookkeeping from Robaws, so that it is taken over one to one in SnelStart.

You need a SnelStart subscription of the type 'inKaart, inBalans, inZicht or inControle' to be able to use the integration.

Activating the integration

You can activate the integration via settings > integrations > SnelStart.
You go through the following steps:

You click on 'Connect with SnelStart'
Enter the SnelStart credentials

Once you have completed these steps, the integration between Robaws and SnelStart is in place.

Do you want to break the integration? That has to be done via SnelStart.

What you can do with this integration

The integration between Robaws and SnelStart supports a great deal:

Export incoming and sales invoices to SnelStart
Sync the payment status of incoming and sales invoices back to Robaws
Import/synchronise GL accounts with Robaws
Export cost centres to SnelStart

Do you work with several companies? Then the imported GL accounts are linked to the correct company: a GL account that is imported for a specific company is only available for that company, and GL accounts that are not linked to a specific company remain available for all companies. You will find more explanation in Using GL accounts.

Important points to watch out for with this integration

Payment terms
Robaws has extensive options for determining the due date of incoming and sales invoices. In SnelStart this is less extensive.

Sales invoices: we calculate the number of days between the date and the due date. That number is passed on to SnelStart as the payment term for the invoice.
Incoming invoices: we set the default payment term on the supplier relation based on the payment condition on the supplier in Robaws. It is not possible to pass on a specific payment term for a single invoice with purchase bookings to SnelStart.

VAT codes
It is not possible to link the VAT tariffs to SnelStart VAT codes manually. The mapping works as follows:

9% -> 'Low' ('Laag' in SnelStart)
21% -> 'High' ('Hoog' in SnelStart)
All other percentages -> 'Other' ('Overig' in SnelStart)

Financial discount/payment discount
SnelStart does not offer any option to pass these on separately. In VAT terms, they are booked through correctly by Robaws.

Direct debit
Do you have a payment condition for which direct debit applies in SnelStart? Then you can create this payment condition in Robaws too.
If you have an active integration with a SnelStart account, you have the option on the payment condition to activate direct debit.
A direct debit is then created when the invoices are exported to SnelStart.
