Procurement, vendor and AP software in Canada
Canada has no e-invoicing mandate, so software decisions here turn on something less visible and more expensive: getting four kinds of sales tax right across provinces, every time, so input tax credits hold up.
The short answer
Canadian companies buying procurement, purchase order, vendor management or AP software should test multi-province tax coding first: GST, HST, QST and PST on the same document, with supplier registration numbers captured so input tax credits are supported. Then check French-language document support for Quebec, cheque and EFT payments, and a two-way sync with QuickBooks Online, Sage, NetSuite, Dynamics 365 or Acumatica.
Four guides for Canadian finance teams
Search volumes in Canada are modest, and the phrasing differs from the US: 'accounts payable software' and 'po software' lead their categories here. Each guide uses the language Canadian buyers use.

A US vendor demoing in Toronto will often show sales tax as a single line. That does not work here. GST applies federally at 5%, participating provinces charge a combined HST instead, Quebec adds QST, and British Columbia, Saskatchewan and Manitoba each run their own PST. An Ontario company buying for a Montreal office and a Vancouver warehouse can see three tax treatments in one order.
The reason this matters is input tax credits. To claim an ITC, a business needs invoices that carry the supplier's details and, for purchases of CAD 100 or more, the supplier's GST/HST registration number. A procurement or AP tool that captures those numbers at onboarding and checks them at invoice time protects money the company is entitled to recover.
Language is the other Canadian factor. Quebec's Charter of the French Language, tightened by Bill 96, requires documents such as invoices and catalogues to be available in French. Suppliers and buyers with operations in Quebec need systems that can produce and store French-language documents without a workaround.

Ongoing
No e-invoicing mandate is scheduled; tax coding across provinces remains the main AP control.
Where Canadian teams feel it first
Mining and natural resources
Remote sites, long supply chains and large capital purchases make PO control and goods receipt the priority. Approvals often happen on a phone at a site with patchy connectivity.
Federal and provincial suppliers
Suppliers to government work under the Canadian Free Trade Agreement and federal contract rules. The federal government also has a target to award at least 5% of contract value to Indigenous businesses, which shows up in supplier data requests.
Manufacturing in Ontario and Quebec
Cross-border buying from the US, supplier documents in two languages and QST make this the most tax-complex mid-market group in the country.
Multi-province retail
Stores in several provinces mean different tax rates on identical purchases. Central purchasing with location-aware tax saves a lot of month-end correction.
Buying software in Canada: FAQ
No. Canada has no federal or provincial B2B e-invoicing mandate. The main compliance concern for AP teams is correct GST, HST, QST and PST coding and keeping invoices that support input tax credits.
The good ones do, usually through tax codes mapped to your ERP or through a tax engine. Many US-built tools assume a single sales tax, so ask to see an order with lines going to Quebec and British Columbia.
Requirements scale with the purchase amount. From CAD 100, the invoice must include the supplier's GST/HST registration number among other details. The CRA publishes the full list.
Under the Charter of the French Language, invoices and similar commercial documents must be available in French. They can also be in another language, as long as the French version is not less prominent.
QuickBooks Online and Sage 50 dominate small businesses. Mid-market companies run NetSuite, Dynamics 365 Business Central and Acumatica, and larger groups add SAP and Oracle.
