Our Verdict
The choice between these two apps is determined entirely by the merchant's specific needs. If a merchant is using QuickBooks Desktop and wants to streamline their accounting process by automatically syncing Shopify sales data, QuickBooks Desktop by Parex is the clear choice. Its high rating and focus on ease of use suggest a positive user experience. However, if a merchant is a German retailer operating a point-of-sale system and needs to comply with the KassenSichV regulation, TSE (KassenSichV) is the only option, despite its low rating. It addresses a very specific regulatory requirement that QuickBooks Desktop by Parex does not.
