200 What each customer owes you right now and how old it is: outstandingOere, overdueOere, overdueCount, oldestDueDate, daysOverdue, collectionsOere, pastDue — the SAME fields and the same source as GET /v1/customers/{id}/balance, so the two can never disagree. Customers with nothing outstanding are not listed; drafts and paid invoices do not count. ⚠️ The figures are point-in-time, and the keyset is the customer’s creation time rather than an amount — an amount changes while you page, which would repeat or drop rows. For the invoice-level detail behind a row, use GET /v1/invoices?customerId=.application/json
