The counter, the ledger, the pay run. Built by one company.
Sero makes point of sale, accounting and payroll software for restaurants, retailers and growing businesses in Canada and the United States — three products from one company, built to the same standards and sold on their own or together.
14-day free trial on every product · Prices in USD, published
Three products. One company that answers for all of them.
Buy one, or run the whole business on all three. Each has its own free trial and its own website, and all of them are built, supported and priced by the same team in British Columbia.
SeroPOS
The point of sale built for the rush.
Point of sale for restaurants and retail — tables, kitchen tickets, inventory, loyalty and online ordering on iPad, Android, Windows and Mac.
SeroBooks
The books, the store, the bank. One ledger.
Accounting that runs the whole business — invoicing, inventory, banking, sales tax, payroll and year-end for Canada and the United States.
SeroPayroll
Payroll for every province. Right to the cent.
Canadian payroll for all 13 provinces and territories — CPP, EI, QPP, vacation, stat holidays, remittances, T4s and ROEs.
From the first sale to the last T4, one company.
A sale at the counter
SeroPOS rings it up — modifiers, split bills, tips, loyalty — prints the kitchen ticket and moves the stock, even when the internet drops.
The books, already posted
SeroBooks keeps one double-entry ledger: invoices and counter sales, GST/HST/PST or US sales tax by line, inventory valued, the bank reconciled.
The people, paid right
SeroPayroll runs the pay by each province’s statute — CPP, EI, QPP, vacation, stat holidays — then the remittance, the T4 and the ROE.
Run them separately or together. See how the platform connects →

Frequently asked questions
What does Sero Technologies make?
Three business products: SeroPOS, a point of sale for restaurants and retail; SeroBooks, accounting software for Canadian and US businesses with inventory, sales tax, payroll and year-end; and SeroPayroll, Canadian payroll for all 13 provinces and territories. Maya, an AI employee, works inside SeroBooks.
Do I have to buy all three products?
No. Each product is sold on its own with its own free trial, and many customers use just one. They are designed as siblings, so when you add a second product it shares the same company, support team and — between SeroBooks and SeroPayroll — the same login.
How much does Sero cost?
SeroPOS starts at $29.99 a month, SeroBooks at $79.99 a month and SeroPayroll at $25 a month for up to 10 employees, all in US dollars. Annual billing costs ten months instead of twelve on SeroBooks and SeroPayroll. Every price is listed on the pricing page.
Is Sero software built for Canada?
Yes. Sero Technologies is a British Columbia company. SeroBooks handles GST, HST, PST and QST for every province, SeroPayroll calculates CPP, EI, QPP and QPIP for all 13 provinces and territories, and both serve US businesses too — SeroBooks covers US sales tax and US payroll.
Can I see the software before I sign up?
Yes. Book a demo and someone who builds the product will walk you through it on a call, or start a 14-day free trial of any product and explore it with your own data.
