Due to the lack of information available, I decided to post a summary of the different stages of my family visit application. The translation was done from Google translate.
1. Once the application is electronically submitted online on the MOFA website.
The following message appears alongside a summary of your application.
يرجى طباعة الطلب وتصديقه الكترونيا من الغرفة التجارية او جهة العمل
Please print the application and electronically ratification of the Chamber of Commerce or the employer
2. Paid the employer 25 SAR and a copy of the application, then they submitted the application to the Chamber of Commerce. The following message appears alongside a summary of your application:
(تم التصديق على الطلب: ( 688888 ) بتاريخ 2013/12/29 (غرفة الرياض)
The ratification of the request: (688888) on 29/12/2013 (Riyadh Chamber)
3. Once the MOFA issue the visa, the following message appears, with a shortened summary of your application:
لرجاء طباعة المستند ومراجعة ممثلية المملكة لإصدار تأشيرة الدخول
Please print the document and audit representation Kingdom to issue visa
Next step, print the visa document, and take it to the embassy in the country of your residence. There, the visa will be issued in your passport.
Application submitted online (Saturday 28th December 2013)
Next day employer submits to Chamber of Commerce (Sunday 29th December 2013).

Hope this helps.
