How does the Horus integration work?

Horus is one of the accounting software packages that Robaws has a direct integration with. You prepare your entire bookkeeping in Robaws and export it one to one to Horus. That way you never have to enter anything twice.

Horus is Belgian accounting software. This integration is therefore only relevant if you work with a Belgian accounting software package.

With the integration you can:

export incoming and sales invoices to Horus;
sync the payment status of incoming and sales invoices back to Robaws;
export cost centres to Horus;
create invoices in Horus as a draft, so that your accountant checks them first.

An integration with Horus is chargeable: you pay an additional cost per integration you set up from Robaws. You can find the current prices on the Robaws pricing page.

Activating the integration

Go to settings > integrations > Horus and go through these steps:

Click on connect with Horus.
Choose the language of your Horus and click on Authorise.
Enter your Horus credentials and click on log in.
Choose the file you want to link to.

After that, the integration between Robaws and Horus is in place.

Do you work with several companies in Robaws? Then you set up a separate integration for each company. To do so, click on default in the top left of the settings and choose the correct company. Each integration is charged separately.

What you set up before you start

The integration is in place, but you cannot export invoices straight away. First arrange these three things.

Importing GL accounts

After activating the integration, the GL accounts from Horus are imported into Robaws. That does not happen immediately, but during the first synchronisation between Robaws and Horus.

Do you not want to wait, or have GL accounts changed in Horus since? Then you synchronise them yourself via settings > general > master data > financial > GL account and the Import from accounting software action button at the top. You can read more about this in Importing GL accounts.

Importing or synchronising GL accounts

Once the GL accounts are in Robaws, you choose them per invoice line. They are sent along when you export to Horus. If you do not fill in a GL account on the line, Robaws falls back on the default GL account from the settings of the integration.

Linking VAT tariffs

Robaws needs to know which VAT tariff in Horus it has to book on. So link every VAT tariff in Robaws to the correct tariff in Horus. Also make sure that your VAT tariffs for sales invoices and incoming invoices are completely split. If that is not yet the case, put it right in the settings first.

You link a VAT tariff like this:

Go to settings > general > master data > financial > VAT tariffs.
Open the VAT tariff you want to link.
Click on the blue pencil next to Horus.
Look up the correct VAT tariff from Horus and click on link.

You will find more explanation in Linking VAT tariffs to VAT codes in your accounting software.

Linking journals

In the settings of the integration you enter a default journal for sales and for purchase. If you do not deviate from those, you are done here.

Do you work with several journals? Then fill in the corresponding Horus code for each journal in Robaws via settings > general > master data > financial > journals, in the journal code field. That code takes precedence over the default journal from the settings.

Settings

Setting	Explanation
Default purchase and sales journal	The journal that is fallen back on for incoming or sales invoices. If you have several journals in Robaws, you fill in the Horus code on the journal itself.
Default purchase and sales GL account	The GL account that is fallen back on for incoming or sales invoices. You can assign a different GL account to a customer, supplier or item. You can also deviate manually on the invoice line.
Default VAT tariff 0% for purchase and sales	A default VAT tariff of 0% for purchases or sales. Amongst other things, this is used to include financial discounts in the lines.
Sync payment statuses of incoming and sales invoices	This lets you have the payment status of incoming or sales invoices synchronised from Horus to Robaws.
Use cost centres for invoice and incoming invoice	This lets you use your projects as cost centres in Horus.
Create invoices as draft	If this is switched on, the invoices are created in Horus as a draft. That way your accountant can check them before they are booked definitively.
