Paperwork: Quotes, Invoices, Books and Staff Documents

Paperwork sits in the "this month, with checks" pile from Lesson 1. The wording is easy work for an AI assistant; the numbers and the rules are not. Here the assistant drafts, and a calculator, your invoicing software and a named person do the rest.

You will finish with a quote template built from a real job or a one-page procedure for a task that lives only in your head, plus a tally of every correction you made. That is page 5 of your AI playbook.

What AI drafts, and what it must not decide

Use your approved assistant for the parts of paperwork that are language: turning rough notes into a clear scope, ordering a document sensibly, writing reminders, suggesting an expense category, and explaining a report you do not understand.

Keep four things out of its hands:

• Arithmetic nobody re-checked. An assistant can add wrongly and sound sure. Google's own notice says Gemini may produce inaccurate information, and Anthropic tells users not to rely on Claude as their only source of truth.
• Tax answers. Those come from your accountant or the Canada Revenue Agency (CRA) business enquiries line, 1-800-959-5525.
• Anything sent to the CRA that a person has not reviewed.
• Decisions about people, such as who gets hired.

Your Lesson 2 never-enter list still applies: no customer names or addresses, bank details, card numbers or social insurance numbers in a chat tool.

A quote from rough notes, then the number check

Dictate or type what you saw on site, just as you would jot it, and add the relevant lines of your own price list. Ask for six parts: scope, inclusions, exclusions, assumptions, how long the quote is valid, and payment terms. The prices come from you. Exclusions and assumptions are the lines that prevent disputes later.

Example arithmetic, replace with your own numbers: 8 quotes a week x 15 minutes saved each = 120 minutes, or 2 hours a week.

Now the number check. Every subtotal, tax line and total comes from a calculator or your invoicing software, never from the draft. Example, replace with your own numbers and your province's rate: $1,200 plus 13 per cent HST, the Ontario rate, is $156 of tax and a total of $1,356.

Fixed details live on your template, not in the AI's draft. If you are registered for GST/HST, the CRA's chart sets out what a business customer needs on an invoice to claim the tax back: under $100, your business name, the date and the total; from $100 to $499.99, also your registration number and the GST/HST charged (or a note that it is included); at $500 or more, also the buyer's name, a brief description and the payment terms. For most businesses the CRA's small-supplier limit is $30,000 of taxable sales, counted over a single calendar quarter or the last four in a row. Once you pass it you must register; the CRA's registration page explains the timing.

Ontario: the province's consumer contract page says that when a written estimate is included in a consumer contract, the final price cannot be more than 10 per cent above it unless the customer agrees to a new price and signs a change to the contract. This is general information, not legal advice; for tax questions, ask your accountant or the CRA.

Getting paid, keeping books, and one fraud check

Write a firm, polite three-message reminder sequence once and reuse it: a few days before the due date, the day after, and one to two weeks late. First check what your invoicing software already sends. On 6 October 2026, for example, Wave's invoicing page listed automatic overdue reminders as a feature of its Pro plan, and QuickBooks' Canadian invoicing page described reminder emails for invoices coming due or overdue. Check each vendor's pricing page for current plans and costs.

Do not let an assistant invent late-fee wording. Under section 4 of the federal Interest Act, when a written contract states interest by the day, week or month, no more than 5 per cent a year can be charged or recovered unless the contract also states the equivalent yearly rate (mortgages are excepted). Have your accountant or lawyer settle that line before it goes on your template. This is general information, not legal advice.

For the books, AI can explain a statement, suggest categories and prepare questions for your accountant, working from descriptions and totals, never account numbers. Your bookkeeper or accountant has the final word. The CRA says to keep records and supporting documents for six years from the end of the last tax year they relate to. Scanned images of paper receipts are accepted only if the scanning meets a national standard, so keep the originals until your accountant confirms yours does. The CRA also says records kept outside Canada and reached electronically from Canada do not count as kept in Canada; ask your accountant how that affects your cloud software.

One fraud check belongs here. The Competition Bureau warns that AI can clone a voice and write messages in a specific person's style, and the Canadian Anti-Fraud Centre describes spoofed emails telling a business that a supplier's payment details have changed. Before paying to new or changed bank details, phone the supplier on a number you already had, never one given in the message. Report fraud to your local police and to the Centre at 1-888-495-8501 or through its reporting page.

Staff documents: procedures and hiring

Small businesses hire rarely but re-explain constantly. Example arithmetic, replace with your own numbers: 20 minutes x 6 times a month = 2 hours a month, or 24 hours a year.

Record a voice note talking through one task from start to finish. Some phones can turn a recording into text; Apple's Voice Memos page explains transcripts on iPhone, so check there whether your model and region are covered. Otherwise dictate straight into the assistant. Ask for numbered steps, a check after each risky step and clear "stop and ask" points. Then let the newest person try it and note where they get stuck.

For hiring, AI can tighten a job posting and draft duty-based interview questions. The Ontario Human Rights Commission advises setting questions in advance from the job's essential duties and asking every applicant the same ones. You remove anything touching a protected ground, such as age, family status, disability or place of origin. A person makes every hiring decision and can explain it. Resumes stay out of consumer chat tools; that is the safe default, since the privacy law covering applicants varies by province and industry.

Ontario employers with 25 or more employees: since 1 January 2026, a publicly advertised job posting must show expected pay or a range no wider than $50,000 a year (not required for jobs paying more than $200,000), say if AI is used to screen, assess or select applicants, say whether it is for an existing vacancy, and carry no Canadian-experience requirement. Interviewed applicants must be told within 45 days of their last interview whether a hiring decision has been made. Elsewhere, ask your province's employment standards office.

An AI-written procedure never replaces training the law requires. In Ontario that includes basic health and safety awareness training for workers and supervisors, Workplace Hazardous Materials Information System (WHMIS) training before workers use hazardous products, accessible customer service training for employees and volunteers, and at least one certified food handler on site during every hour a food premises operates. This is general information, not legal advice.
