• Experience working in a stand-alone AP position with full ownership of the process .

• A strong understanding of GRNI and reconciliation processes .

• Strong knowledge of PO matching, invoice processing and supplier statement reconciliations .

• Previous experience preparing payment runs and working with banking/payment platforms.

• Strong communication skills and the ability to build effective relationships with internal stakeholders and suppliers.

• A proactive, adaptable and continuous-improvement mindset .

The Ideal Candidate This role would suit an experienced AP professional who is comfortable being the go-to person for accounts payable , rather than someone who has only owned one part of the AP process.

If you have experience managing invoices from receipt through to payment , understand how GRNI should be monitored and cleared , and enjoy taking ownership of a busy AP function, we'd be keen to hear from you.
