IONATE is a deep-technology scale-up building the technology backbone for smart electricity grids. Our London team is looking for an Accounts Payable Assistant to support the Finance function on a full-time basis.
Requiring solid purchase ledger experience, you will work closely with our AP Supervisor and Financial Controller, supporting our UK and Austrian entities. You will play a key role in keeping the purchase-to-pay cycle running smoothly, ensuring suppliers are paid accurately and on time, and that records are clean and audit-ready.
This role focuses on delivering the day-to-day accounts payable function while helping us improve and document processes as the business scales. You’ll work with colleagues across the company to streamline approvals, strengthen controls, and maintain high-quality data in ExpenseIn and Xero (multi-currency).
What you will do:
- Own the end-to-end AP process: invoice capture, coding, approvals, posting, and payment
- Be the first point of contact for supplier and internal AP queries; resolve discrepancies promptly and professionally
- Process purchase invoices and credit notes in ExpenseIn and Xero (including multi-currency), ensuring correct VAT/tax treatment where applicable
- Manage employee expenses and company credit card transactions, ensuring policy compliance and accurate coding
- Maintain the purchase order process: ensure POs are raised for committed spend, obtain approvals, and match PO to invoices
- Prepare weekly payment runs and ad-hoc payments, ensuring payments follow approval controls and agreed supplier terms
- Reconcile supplier accounts and statements; investigate and clear aged items, duplicates, and unmatched transactions
- Perform bank reconciliations and support month-end close activities related to AP
- Manage the Finance shared mailbox, prioritising queries and maintaining clear audit trails
- Support onboarding and maintenance of supplier master data (e.g., bank details) in line with internal controls
- Manage HMRC customs reporting requirements and payments relating to import taxes on supplies
- Provide reporting and supporting documentation for financial reporting and audit requests, and contribute to continuous improvement initiatives
