About the role

Join our dynamic team at LNG Grain as a Purchase to pay Accountant.


The role will be leading the Purchase-to-Pay (PtP) cycle of the Grain Isle facility and JV group companies (~GBP300m revenue, ~£1.1bn assets, ~250 employees) and to ensure it is carried out efficiently, effectively and in line with best practice.

To ensure right‑first‑time purchasing, accurate invoice processing, compliant payments and optimised working capital. Lead the configuration, implementation, operation and continuous improvement of PtP processes within the Tier 2 ERP (e.g. Microsoft Dynamics or NetSuite), embedding strong controls, data integrity and audit readiness consistent with private‑equity governance.

You will partner with Procurement, Operations/Engineering, Stores, and Finance to translate operational needs (maintenance, outages, projects, spares) into well‑controlled purchasing and timely supplier payments, while delivering clear visibility of spend, liabilities, and cash requirements.

This role is based from our world-class facility in the Isle of Grain, Kent, and you can enjoy our hybrid working from office and home, with the expectation of being in the office at least 3 times a week. Please note, due to the location of the site you must have a full UK driving licence and car to be able to travel to site.

What you'll do

  • Define, operate, and continuously improve the end to end PtP process (requisition → PO → receipt → invoice → payment → reporting)
  • Maintain clear SOPs, RACI, and close calendar for AP accruals, GRNI clearing and supplier payment runs
  • Enforce Delegation of Authority (DoA) for approvals and embed independent verification controls
  • Own vendor master data standards (naming, tax/VAT details, bank accounts, payment terms, categories).
  • Execute supplier onboarding controls: KYC, bank detail verification, sanctions checks, conflicts of interest, GDPR compliance
  • Prevent duplicates and maintain data quality through periodic reviews and change control
  • Ensure all spend follows PO-before-commitment policy (exceptions tightly controlled)
  • Configure and maintain ERP approval workflows, budget checks, and coding (GL, cost centre, project/site)
  • Achieve high three way match rates (PO, receipt, invoice); minimise manual overrides and ensure documented justification
  • Plan and run payment cycles (BACS/Faster Payments), ensuring approvals, segregation of duties, and secure bank file handling
  • Issue remittances; manage supplier queries/escalations and maintain positive supplier relationships
  • Align payment timing to working capital targets (DPO), early payment discounts, and cash flow forecasts
  • Configure PtP modules: vendor master, PO policies, approval workflows, matching rules, tax codes, payment terms, and bank integrations
  • Lead data migration/cleansing (vendors, open POs, GRNs, AP open items) and validate with trial balances/recons
  • Develop and run UAT/test scripts for PtP scenarios; log defects and sign off fixes; create user guides and deliver training
  • Increase automation (recurring POs, service entry sheets, supplier portal/e invoicing, exception rules)
  • Map and streamline PtP processes; deliver improvements (supplier portal, e invoicing, touchless matching, dynamic discounting).
  • Standardise templates and introduce exception KPIs; reduce manual interventions and cycle times.
  • Contribute to broader finance transformation and private equity value creation initiatives.

What you'll need

  • At least five years end‑to‑end PtP/AP experience in complex, operational businesses
  • Experience of PE reporting environment and/or US Corporate reporting requirements preferred
  • Experience of working in a SME scaled business and large company environments
  • Strong understanding of UK VAT rules and invoice compliance; confident in matching, coding, and AP/GL reconciliations.
  • Hands-on experience with integrated business software (Tier 2) finance/procurement modules including its design, implementation and operation
  • Experience with OCR/e‑invoicing and supplier portals
  • Strong internal control perspective and ability to identify and implement improvements to processes and procedures

  • Familiarity with capital projects / capex governance

What you'll get

A competitive salary between £42,781 - £50,738 per annum– dependent on capability.
