About Swap

Swap is the infrastructure behind modern agentic commerce. The only AI-native platform connecting backend operations with a forward-thinking storefront experience.

Built for brands that want to sell anything - anywhere, Swap centralises global operations, powers intelligent workflows, and unlocks margin-protecting decisions with real-time data and capability. Our products span cross-border, tax, returns, demand planning, and our next-generation agentic storefront, giving merchants full transparency and the ability to act with confidence.

At Swap, we’re building a culture that values clarity, creativity, and shared ownership as we redefine how global commerce works.

About the Role

We are looking for a Billing Associate contractor (12 Month FTC) to support Swap’s day-to-day billing operations, primarily focused on Shipping billing and customer onboarding. This is a hands‑on role requiring strong attention to detail, confidence working with data and an interest in using systems, automation and AI to improve Finance operations.

This role suits a problem solver that thrives in a scale-up environment — comfortable operating both strategically and at a detailed transactional level. You’ll be as confident reviewing billing issues as you are improving processes, implementing systems, and solving operational bottlenecks.

The responsibilities of this role can change in line with your skills in the future and this is an opportunity to shape this role as Swap grows.

Key responsibilities

• Manage Finance onboarding for new customers, including billing setup, Direct Debit mandates and customer information

• Support customer termination and churn processes, including termination fee calculations and coordination with Credit Control

• Perform first-invoice reviews and investigate initial billing discrepancies for newly onboarded customers

• Prepare and review Shipping billing calculations and resolve related customer and internal queries

• Perform billing reconciliations, investigate exceptions and maintain accurate billing records and supporting documentation

• Support implementation and testing of new billing tools designed to consolidate data and automate existing manual processes

• Support the adoption of automation and AI‑driven workflows across billing, reconciliations and exception identification

• Provide general Billing and Credit Control support and contribute to improvements in processes, controls and data quality

What we would like to see:

• 2+ years’ experience in Billing, Accounts Receivable, Finance Operations or a similar role

• Strong Excel skills and confidence working with large datasets

• Strong numerical skills and attention to detail

• Ability to investigate discrepancies and follow issues through to resolution

• Experience with transactional or usage‑based billing would be beneficial
