AR Yeah It's That Important

Book returns and inefficient billing -- nothing can snarl up your
bottom line faster. iPUB makes sure you account for every
return and track every invoice to collect exactly what you are
owed.

Your publishing business depends on reconciling book returns to
control cash flow. At the same time you need to know your invoices
are received and paid promptly.

In a perfect world, bookstores take credit only for books that they actually return. But in the real world, we all know that many invoices are paid with credits charged-back from book returns that either are slow to arrive or never arrive at all.

iPUB tracks these credits and reconciles them against books actually returned. So you know exactly what you are owed, iPUB tracks each transaction, invoice and payment.
