However, choosing outsourced accounts payable service providers isn’t always a sure-shot option to save on in-house operations due to human mistakes like manual data entry errors, default cross-border payment solutions (like auto-converting to CAD), etc. Canadian businesses lose an estimated 15 to 25 CAD per individual mistake when correcting manual data entry errors. On the other hand, faulty cross-border payments cost Canadian SMEs 5.5% to 7% per transaction.
Maintaining an in-house team is way costlier, and human errors in outsourced accounts payable services also do significant financial damage, so what is the option for SMEs, startups and accounting firms in Canada for cost-effective accounts payable services? Well, in such a case, there is only one option left for accounting firms and small enterprises in Canada, which is choosing wisely from the best outsourced accounts payable services.
Why Canadian Businesses Are Outsourcing Accounts Payable in 2026
Canadian businesses are outsourcing accounts payable in 2026 to combat acute finance talent shortages, reduce processing costs, and eliminate reliance on manual data entry. Partnering with top AP outsourcing firms in Canada allows businesses and accounting firms to scale operations flexibly and refocus internal staff on revenue-generating strategies. Let’s dive deep into this.
Why are Canadian businesses outsourcing finance operations?
There is not a specific reason that is forcing Canadian businesses to outsource finance operations. A cluster of challenges obliges Canadian businesses to outsource their finance operations to top outsourced accounts payable services in Canada, such as rising labour costs due to inflating accountant salaries, talent shortages in the financial sector and security risks with sensitive data.
Finance talent shortages
Canada’s accounting talent shortage is a structural crisis driven by massive retirements of Baby Boomers (people born between 1946 and 1964). According to some stats by Global Recruitment Experts, in the last decade Canada has seen a 30-40% drop in CPA programme enrolment. The remaining local talent is being poached by US firms for higher salaries.
Rising labour costs
Rising labour costs in Canada in accounting are a result of an ongoing talent shortage and increasing skill gaps. In such an inflated market, a median Certified Public Accountant (CPA) can cost an accounting firm 150,000 CAD (estimated); as a result, accounting firms in Canada are turning to offshore outsourcing and automation to stabilise margins. Recent data on accounting in Canada shows a tight market where 68% of finance managers struggle to hire and retain talent.
Security Risk with Sensitive Data
Despite choosing top accounts payable outsourcing companies, accounting firms in Canada are always exposed to several critical risks, primarily centred around data breaches, fraud, loss of direct control, and compliance violations. According to the 2026 AFP Payments Fraud and Control Survey Report, the average cost of a data breach for Canadian organisations sits at CAD 6.98 million. The same report suggests 76% of business organisations in Canada experience attempted or actual payment fraud.
Compliance requirements
For Canadian accounting firms, the primary compliance challenges in outsourcing involve meeting the CPA Canada professional standards, ensuring secure handling of sensitive data under the Personal Information Protection and Electronic Documents Act (PIPEDA), and navigating complex Canada Revenue Agency (CRA) tax regulations. The problem with the outsourced accounts payable service is that if an outsourcing accounting firm fails to comply with the concerned authority, the penalty will be on the Canadian financial service firms or business organisations. Still, business organisations in Canada choose AP outsourcing companies for accounts payable services.
How We Selected the Best Accounts Payable Outsourcing Companies
To select the best outsourced accounts payable services, we have criteria to evaluate the organisation’s capability as an outsourced accounting firm.
Evaluation Criteria
Canadian accounting expertise
We select the AP outsourcing companies in Canada that adhere to the Canada Revenue Agency (CRA) tax rules, GST/HST and PST remittance regulations and Canadian generally accepted accounting principles—specifically ASPE (for private entities) or IFRS (for public companies).
AP process maturity
The second parameter in our criteria is accounts payable process maturity, which means whether an outsourcing accounts payable service provider is still using traditional paperwork or utilising dedicated software to streamline your cash flow.
Security & confidentiality
Before finalising a service provider from top outsourced accounts payable services in Canada, the most important factor we consider is data security. We only consider firms that protect against invoice scams, phishing attacks, and unauthorised fund transfers, ensuring payments only go to validated vendors.
ERP integrations
ERP software plays a key role in automating internal financial systems, as it allows invoices, payments and vendor data to sync automatically, eliminating the risk of human errors that cost SMEs and startups a significant amount. That’s why we always consider AP outsourcing companies that integrate ERP into their operating system.
Invoice processing accuracy
Another important factor that we always find in an outsourced accounts payable service provider is how accurately it processes the invoices, as inaccurate invoice processing can cause severe financial leakage, operational bottlenecks, and damaged vendor relations.
Turnaround time
We only mention top accounts payable outsourcing companies with a fast turnaround time. The speed of processing an invoice from receipt to payment matters a lot, as it saves time for organisations as well as creates a better image in the market.
Industry experience
Among all the above-mentioned factors that we consider in selecting the best outsourced accounts payable service providers, industry experience ranks top among all of them.
Client support
Another factor that we keep our eyes on most while selecting an outsourced accounts payable service provider is client support. We only consider top AP outsourcing firms Canada that have extraordinary client support.
Scalability
We always consider outsourced accounts payable services that can seamlessly expand invoice and payment processing workflows to handle higher transaction volumes without proportionately increasing headcount or costs.
