Frequently asked questions
Who writes the SeroPOS blog?
The SeroPOS team at Sero Technologies writes the posts, drawing on the questions restaurant and shop owners ask us when they set up their point of sale. Posts are revised when the product or the facts change, so the advice and the SeroPOS screens they describe stay current with the app and the back office.
Are the comparison posts fair to other POS systems?
We aim for that. Comparison posts use general, publicly available information about other systems as of 2026, and avoid quoting their prices, which change often. Every system covered is used by successful businesses, and the right choice depends on yours. Check the details on each company's own website before you decide which system to choose.
Do the posts cover Canadian businesses?
Yes. SeroPOS is built in Canada, and a group of posts covers Canadian topics such as GST, HST and PST, card processing for Canadian pizzerias, opening a pizza shop in Canada and connecting a POS to QuickBooks in Canada. Many other posts apply equally to businesses in the US.
