Payment Terms Net 30 in Canada: Rules and Timelines

Payment terms Net 30 in Canada mean that the buyer must pay the full balance of an invoice within 30 calendar days of the invoice date. The clock begins on the calendar day the invoice is issued, not when the client opens it. For construction projects governed by provincial prompt payment legislation, statutory rules often override this 30-day window with mandatory 28-day payment deadlines.

The Definition and Mechanics of Net 30 Terms

Net 30 indicates that the "net" amount—the total balance after any discounts, trade credits, or upfront deposits—is due in full precisely 30 days later. Unless an underlying contract specifies otherwise, these 30 days are calendar days, not business days. If you send an invoice on May 3, the payment must reach your account by June 2. If the thirtieth day falls on a Saturday, Sunday, or statutory holiday, Canadian commercial practice generally shifts the enforceable due date to the next immediate business day.

Businesses across Canada use Net 30 as a default trade credit term. When you offer Net 30, you act as an unsecured lender to your client. You provide work, procure parts, or deliver professional advice upfront, carrying the cost of payroll and overhead for a full month before receiving compensation. For small operators, tracking these due dates across multiple provincial tax jurisdictions requires clear systems. Many service businesses track their receivables using BoltBill Pro to prevent unpaid accounts from slipping past the 30-day mark.

Understanding this cash gap is essential for sole proprietors and independent tradespeople. If your company pays suppliers on Net 15 terms but bills your own clients on Net 30, you face a recurring working capital deficit of at least two weeks on every project cycle.

Provincial Legislation and the Contractual Legal Framework

Net 30 terms originate in contract law. When both parties sign an agreement containing Net 30 terms, or when a buyer issues a purchase order referencing them, both sides are bound by that timeline. However, statutory law can supersede your contract wording, particularly in the construction sector.

In Alberta, the Prompt Payment and Construction Lien Act (PPCLA) governs commercial construction agreements. Under Section 32.2 of the PPCLA, an owner must pay a general contractor within 28 calendar days of receiving a "proper invoice". The general contractor must then pay its subcontractors within 7 calendar days of receiving payment from the owner. Writing "Net 30" on a construction invoice subject to the PPCLA creates an enforceable conflict: the statute mandates payment within 28 days, rendering a contractual 30-day term non-compliant for the owner's statutory obligation.

Ontario enforces an identical 28-day owner payment requirement under its Construction Act. For consultants, contractors, and specialized trades working on improvements to land or premises, provincial prompt payment statutes take legal precedence over standard Net 30 clauses. If you operate outside construction—such as in software consulting, direct client freelancing, or non-site professional services—standard contract law applies, and your stated Net 30 terms govern the agreement without statutory interference.

Late-payment interest cannot simply be invented after the fact. Under Section 4 of the federal Interest Act, no interest rate exceeding 5% per annum can be collected on written agreements unless the contract expressly states the rate as an annual percentage. If your invoice states "2% per month on overdue accounts" without stating the equivalent annual rate (24% per year, or 26.82% compounded), you may be legally restricted to claiming only 5% annually in a Canadian court.

Worked Example: How Net 30 Operates on a Real Project

To see how Net 30 coordinates with Canadian taxes and holdbacks, consider a mechanical drafting specialist registered in Calgary, Alberta, invoicing an architectural firm for completed drawings.

The agreement specifies a flat fee of $6,000.00 CAD on standard Net 30 terms. Because the work is performed and delivered in Alberta, the federal Goods and Services Tax (GST) applies at 5%. Provincial sales taxes do not exist in Alberta.

• Agreed professional fee: $6,000.00
• GST (5% of $6,000.00): $300.00
• Total invoice amount: $6,300.00
• Invoice date: October 1
• Payment due date (30 calendar days): October 31

On October 1, the drafter delivers the completed package along with a compliant invoice that clearly displays their business name, the client's legal name, a unique invoice number, their nine-digit CRA Business Number with the RT program identifier, and the payment terms. The entire $6,300.00 must be remitted by October 31.

Now contrast that scenario with a plumbing sub-trade working on an active commercial building renovation in Edmonton under the PPCLA. The sub-trade submits a monthly progress claim of $10,000.00 plus GST on Net 30 terms. Under the PPCLA, the mandatory 10% statutory lien holdback applies immediately to the value of the work.

• Value of work performed: $10,000.00
• Less 10% statutory holdback: -$1,000.00
• Net billing before tax: $9,000.00
• GST (5% on the net billed amount, or on the gross depending on agreement structure): $450.00
• Current payable balance: $9,450.00

Even though the invoice indicates Net 30, the general contractor holds back the $1,000.00 principal until the lien period expires—which in Alberta is 60 days following total completion or abandonment of the contract (or 90 days for improvements to oil and gas wells). The sub-trade collects $9,450.00 within the agreed period, while the retained $1,000.00 remains uncollected until the statutory holdback release date.

Common Misconceptions About 30-Day Terms

The most frequent operational error among newly self-employed individuals is assuming that Net 30 includes 30 business days. It does not. An invoice issued on July 1 is due July 31, regardless of how many statutory holidays or weekend days sit inside that month. Counting business days stretches the credit term to nearly six full weeks, draining your bank balance.

A second widespread misconception is that the 30-day timeline begins when the client's accounts payable department approves or "processes" the file. Unless a master services agreement specifically establishes an inspection or review period prior to delivery, the legal term begins on the invoice issue date. In Alberta prompt payment environments, the clock starts upon physical or electronic receipt of the "proper invoice" by the client, making proof of delivery critical.

A third error is confusing Net 30 with early-payment discount terms such as 2/10 Net 30. A 2/10 Net 30 agreement gives the client a 2% discount on the gross fee if they settle the bill within 10 calendar days; otherwise, the full balance is due at 30 days. Offering 2/10 Net 30 on a 5% margin project will destroy your profitability, whereas standard Net 30 protects your agreed gross fee while setting a firm deadline.

Finally, many business owners believe that printing "Payment Due Upon Receipt" results in faster payment than Net 30. In practice, enterprise accounts and public agencies often ignore "Upon Receipt" designations because their internal accounting cycles run on weekly or monthly batch payment runs. Supplying a specific date under Net 30 gives your client an unambiguous deadline to enter into their accounts payable ledger.

Tax Compliance, Record-Keeping, and Late Payment Remedies

Operating on Net 30 terms carries clear obligations under Canada Revenue Agency rules. If you use accrual accounting—which is mandatory for incorporated Canadian companies and standard practice for most growing enterprises—you must report income in the taxation year the invoice was issued, regardless of whether your client pays within the 30 days or leaves you waiting six months.

The CRA requires businesses to charge tax according to the place of supply rules. The rate depends on where the client receives the benefit of the service:

Under Section 230(4) of the federal Income Tax Act, you must keep complete records and supporting documentation—including every outbound Net 30 invoice, bank receipt, and payment record—for a minimum of six years from the end of the last tax year to which they relate. If you bill a client on Net 30 in November 2024 and receive payment in January 2025, that transaction affects your records across both years, and you must retain both copies until at least the end of 2031.

When an invoice passes day 31 without payment, prompt action preserves cash flow. First, send a statement of account referencing the original invoice number, issue date, and overdue amount. Second, verify that the initial document contained your valid nine-digit business number; missing tax numbers are the leading administrative reason accounts payable departments pause payment.
