Why is SunSystems so popular with insurance companies?

Insurance is an interesting business - there are times when the customers (policy holders) are also creditors (policy claimants). As a result the business needs to deal with the same entity in parallel. The SunSystems uniledger allows a single entity to be classified and managed as both a debtor and a creditor. This makes it possible to deal with the entity separately as one or the other, as a combined entity in transactional processing and also analysis and reporting.
