When is Loyverse a good choice?
If you want to start at zero cost, core selling and basic reports are enough, and a translated interface with English support does not bother you, Loyverse is a mature, popular global option.
When is Cash Dukkan the better fit?
If your shop is in Jordan and you want a system that thinks in Arabic rather than translating into it: dinar invoicing, customer debts the way the local market actually runs them, and support that answers in your language. And if you prefer a one-time cost over a never-ending monthly subscription, the math after two to three years clearly favours Cash Dukkan.
Most importantly: try both. Cash Dukkan's 7-day trial includes everything, so the real comparison happens at your own counter.
