We’re looking for a Senior Advisor to join the Billing and Administration team within our wider Co-op Business Services (CBS) organisation. CBS is made up of a number of diverse teams dedicated to delivering high-quality, reliable, and cost-effective business services across our Co-op. You’ll play a key role in helping CBS to support and realise our group vision of ‘co-operating to build more value for member owners every day’.

In this role, you’ll support our Billing and Admin Manager with invoicing dispute management, invoice processing, and other administrative tasks. We’ll look to you to review and process large volumes of invoices and make sure all billing processes run smoothly.

It’s important that our Co-op can manage our billing activities effectively. Your involvement in managing our invoices, processing orders and payments, and resolving disputes will help to ensure this.

• Review and process high volumes of invoices
• Process and manage supplier disputes and recommended solutions

• Identify opportunities to improve our processes and work more efficiently
• Own the production and review of process documentation
• Provide new, and current, team members with the training and support they need to thrive

We’re committed to making our roles as accessible as possible, so we only ask for the minimum criteria. To thrive here, you’ll need to bring:

• A basic understanding of accounting principles
• Strong Microsoft Excel skills (e.g., pivot tables, VLOOKUPs)
• A willingness to learn new things, systems, and processes
• Good communication and relationship-building skills
• Confidence to challenge processes and share improvement ideas
• The ability to support colleagues and distribute work across team members

At Co-op, we’re owned by our members. And because we’re owned by you, we can do right by you. So when you join us, you’re not just taking a job, you’re joining a movement. We’re an organisation that puts people and communities first, and we’re powered by purpose. We want this to be a place where you can thrive, so you’ll also receive:

• 28 days holiday (pro-rata) plus bank holidays
• A pension with up to 10% employer contributions
• 30% discount on Co-op products and 10% off other brands
• Stream – early access to a percentage of your pay as you earn it
• Virtual healthcare including GP appointments, mental health support, nutrition and fitness advice
• 24/7 colleague support service
• Training and support for your development and career progression
• Cycle-to-work scheme

We’re building diverse teams that reflect the communities we serve. We welcome applications from everyone, and our support centre is an inclusive environment where all our colleagues can thrive.

If you have a disability, we’ll make reasonable adjustments to support you through the recruitment process. We’re also proud to be part of the Disability Confident scheme - if you’re disabled and you meet the minimum criteria for this job, we’ll guarantee you an interview.
