Accounts Payable Specialist

Accounts Payable Specialist

Greenhawk is one of North America’s leading equestrian retailers, operating a growing network of stores and e-commerce businesses across Canada and the United States.

We are seeking an organized, capable Accounts Payable Specialist to take ownership of the full AP cycle. This is not simply an invoice-entry role: you will manage invoices through to payment, resolve issues with vendors and internal teams, and help improve the systems and processes behind the work. This is a work at office role located in Mississauga, Ontario.

The Role

You will be the central point of contact for vendors and for our Purchasing, Warehouse and store teams on invoice and payment matters. You will manage a high-volume AP function accurately, keep payments on schedule, investigate discrepancies, and support month-end reporting.

What You Will Do

• Manage the shared AP inbox: log, route and action invoices, and respond promptly to vendor payment inquiries.
• Process inventory invoices in Sage 300, completing detailed three-way matching against purchase orders and receiving reports, including quantities, pricing, freight and tax.
• Investigate and resolve discrepancies with Purchasing, the Warehouse and vendors; follow up on vendor credit notes.
• Process service, utility and freight invoices through Beanworks.
• Reconcile vendor statements monthly and maintain accurate vendor records, payment terms and supporting documentation.
• Prepare weekly payment runs, including ACH/EFT, bill payments and wires, within agreed payment terms and approval controls.
• Process employee expense reports, corporate credit-card reconciliations and recurring monthly allocations.
• Manage import documentation for overseas purchases.
• Support month-end close, including AP aging reviews, accruals and reconciliation of AP to the general ledger.
• Identify practical process improvements as we replace manual steps with better imports, controls and automation.

What You Bring

• At least three years of full-cycle accounts payable experience in a fast-paced environment.
• Strong experience with three-way matching, vendor reconciliations and payment processing.
• Solid Excel skills and confidence using AI tools responsibly to improve accuracy and efficiency.
• Working knowledge of HST, GST and PST.
• Strong attention to detail, sound judgment and the ability to organize competing deadlines.
• Clear, professional communication with vendors and internal teams.
• A practical, solutions-oriented approach when something does not match or does not make sense.

Assets

• Experience with Sage 300 and/or Beanworks.
• Experience in a multi-entity organization or with U.S./USD payables.
• Accounting diploma, bookkeeping designation or progress toward CPA certification.

If you take pride in accurate work, enjoy solving problems and want to build better AP processes—not just process invoices—we would like to hear from you.
