Billing As part of the team that designs the billing experience for the customer, you will be tasked with building processes that will impact how Xendit collects fees and charges from the merchant. In designing this system we are looking to minimize the friction involved in settling an invoice. This can be through providing different methods of settling the invoice, providing more flexible payment terms, or creating automated processes that will conveniently settle the billing amount for the merchant without any action needed. As billing performance comes down to how easy and frictionless we can make the experience for the merchant, decreasing the steps needed and procedures in the way of settling an invoice is a key to providing a well-rounded billing experience for the customer. Mission Accurately and reliably deliver billing solutions for all customers. Accuracy The main pillar for our billing documents is accuracy - as this is the first impression that the merchant can receive in order to build trust with Xendit. When billing documents are correctly calculated with all the fees & charges clearly laid out, the merchant will be able to trust that the billing amount is the right amount. Creating accurate billing documents requires the ability to handle large volumes of data and understanding the differences between the products that make up the transaction data. In combination with this, the transaction data will need to be manipulated to include the merchant data with agreed rates and any special arrangements. Putting all of these pieces together requires curiosity to understand how transactions are designed at the product level in order to aggregate them into a convenient and accurate documentation for the merchant. Reliability Every month Xendit Group produces more than a thousand customer invoices for all our merchants and delivers them to customers on a set schedule. Every month the merchant list grows but the set schedule needs to be maintained for internal reporting and customer agreements. To tackle this issue our Billing team builds an iterative robust system that is prepared to scale with our merchant base whilst maintaining the reliability of delivery. Problem-solving and investigative traits are a huge assets of being able to evaluate the current system to prepare it for the next iteration and set it in the right standing for scalability.
