Senior Accounts Receivable & Billing Specialist

We are hiring a Senior Accounts Receivable & Billing Specialist to own two critical parts of our finance operation: accurate, timely billing and disciplined management of aged debt.

This person will ensure invoices are issued correctly and on time, customer accounts remain clean and well controlled, cash is collected in line with agreed terms, and overdue debt is actively reduced. The role combines financial control, operational rigour, and stakeholder management. It requires someone who is precise, persistent, commercially aware, and confident driving issues through to resolution.

What you’ll be doing:

Billing

• Own accurate and timely billing across recurring, milestone, and ad hoc invoicing
• Ensure invoices, credit notes, and adjustments are raised in line with agreed customer terms
• Ensure all billing is fully supported by the right approvals, commercial terms, and documentation
• Resolve billing issues quickly with internal teams to avoid delays to invoicing and cash collection
• Improve billing quality by reducing errors, disputes, and rework

Accounts receivable

• Maintain a well-controlled sales ledger, with accurate customer account data, payment terms, and balances
• Ensure cash receipts are posted and allocated accurately and promptly
• Reconcile customer accounts and resolve discrepancies in a timely manner
• Keep the ledger clean, current, and properly controlled
• Support month-end close through reconciliations, reporting, and AR analysis

Aged debt and collections

• Take ownership of overdue debt and drive collection activity consistently
• Lead collection activity through professional, persistent follow-up with customers
• Prioritise collection efforts based on risk, value, ageing, and payment behaviour
• Identify root causes of delayed payment and work across the business to remove them
• Drive disputed invoices through to resolution rather than allowing them to stall
• Escalate high-risk or materially overdue accounts where appropriate
• Support decisions on credit holds, payment plans, and bad debt exposure

Reporting and improvement

• Produce aged debt reporting with clear commentary on risks, disputes, and actions
• Monitor collection performance, overdue balances, and debtor trends
• Contribute to short-term cash visibility through AR reporting and collections insight
• Strengthen processes, controls, and ways of working across billing and collections

What you need to succeed:

Experience:

• Proven experience in accounts receivable, billing, credit control, or sales ledger, with clear ownership of both invoicing and aged debt
• Strong hands-on experience in billing, cash allocation, reconciliations, and collections
• Confidence chasing overdue payments and handling difficult conversations professionally
• Strong judgement on when to push, when to escalate, and how to protect customer relationships without compromising financial discipline
• Ability to work across finance, sales, and operations to resolve issues quickly
• Strong Excel and finance systems capability
• High attention to detail, strong organisation, and consistent follow-through
• Experience improving processes and controls, not just operating within them

Skills & Competencies:

• Firm but professional
• Persistent and calm
• Highly organised
• Commercially sensible
• Not afraid to chase, challenge, and close loops

What does success look like:

• Billing is accurate, timely, and well controlled
• Customer accounts are maintained to a high standard, with minimal unreconciled items or unallocated cash
• Aged debt is actively managed and overdue balances are reduced
• Disputes and payment blockers are resolved quickly and do not sit unresolved
• Finance leadership has clear visibility of receivables risk, collections activity, and cash performance
• Processes and controls across billing and accounts receivable become stronger over time
