A POS system cost can vary. Some POS software options are free, with nominal fees for POS hardware such as a card reader or counter terminal. Other cloud-based POS system options will provide free software and hardware but may charge a monthly fee and/or a percentage of the payments it processes.
A larger POS terminal may cost upwards of $1,000 for initial costs and then a small monthly fee or payment percentage, depending on the POS system provider.
