From $25 / month · USD
How it fits together

From the first sale to the last T4, one company.

01 · Sell · SeroPOS

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.

02 · Account · SeroBooks

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.

03 · Pay · SeroPayroll

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 →

Guides

Practical reading for owners and bookkeepers

Point of sale

How to choose a restaurant POS system: a practical buyer’s guide

A restaurant POS is the system your staff touch hundreds of times a shift. This guide walks through how to match one to your service style, what to test, and which costs hide behind the monthly price.

Operations

How to start a restaurant in Canada: the systems checklist

Menus and design get the attention, but a restaurant also needs a set of registrations and systems in place before the first guest sits down. This checklist covers the back-office side of opening in Canada.

Operations

How to reduce food cost with recipe costing

Food cost is one of the two biggest numbers in a restaurant’s P&L, and the one you can move fastest. Recipe costing shows what each plate should cost, so you can find out where the rest is going.

Payroll

How to run payroll in Canada, step by step

Running payroll in Canada means calculating gross pay, taking the right deductions, paying employees, sending the deductions to the CRA on time, and filing slips at year-end. Here is the whole process in order.

Payroll

How to calculate vacation pay in Canada

Vacation pay in Canada is a percentage of what an employee earns, set by the province or territory where they work. Here is how to work out the percentage, what it applies to, and how to pay it.

Payroll

Statutory holiday pay by province: how each formula works

Every province sets its own holidays, eligibility rules and pay formula. Here is how statutory holiday pay works in each part of Canada, and what to pay someone who works the day.

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.
