Quick answer
To keep selling through power cuts, put the terminal, router, receipt printer and scanner on a UPS sized for your needs, and choose POS software that works offline and syncs when the internet returns. Battery-backed Android terminals add another layer for small shops. Plan for both power and internet, because losing either can stop a cloud-only till.
