Our Verdict
The choice between these apps depends entirely on the merchant's specific needs. If a merchant is selling items by weight (e.g., produce, meat) and requires a solution to automate pricing, inventory tracking, and discounts within Shopify POS, then F: Sell by Weight for POS is the relevant choice, assuming the merchant is willing to try an app with no reviews. However, the merchant must be willing to beta test the app at this time.
Conversely, if a merchant operates in Germany, Austria, or Switzerland and requires a solution to comply with TSE and RKSV regulations, then OpenFiskal TSE & RKSV is the clear winner. Its established reputation and robust features make it the go-to option for merchants prioritizing fiscal compliance. Merchants who require both weight-based selling and fiscal compliance will need to find a way to integrate these separate functions, or find a different single application that covers both use cases.
