The customer wanted to build a product that would allow users to take a picture of an invoice, send it over WhatsApp, Slack or email. The product would use an OCR system coupled with a machine learning model to identify the attributes of an invoice including the IBAN, amount, due date, currency and the recipient details. Reminders needed to be sent to customers when an invoice was nearning it's due date. Additional features included scheduling payments, conversations chat via WhatsApp, support for payment methods such as cards & open banking. A rich payment widget that can be embedded on any website to collect payments was also required.
