This role is essentially the technical backbone of the Accounts Receivable process, acting as the primary link between finance operations and digital payment platforms. Crown is looking for a specialist who can own the entire lifecycle of customer invoicing portals—from the initial technical setup and user access management to the high-stakes troubleshooting required when an invoice fails to transmit.

You won't just be "inputting data"; you’ll be the process expert who ensures the "Master Sheet" of portal configurations remains the ultimate source of truth. A typical day involves triaging busy invoicing inboxes, manually correcting and re-uploading documents to platforms like Tungsten, and collaborating with IT to bridge communication gaps.

Because these platforms are constantly evolving, there is a heavy emphasis on documentation and continuous improvement. You’ll be responsible for turning complex billing workflows into clear Standard Operating Procedures (SOPs), ensuring that as the company scales, the knowledge of how to get paid stays organized and accessible. It’s a fast-paced role that requires a mix of financial literacy, technical troubleshooting, and the administrative discipline to meet tight month-end deadlines.
