Both Billings Pro and Billings Pro Server were updated earlier today, bringing both to version 1.6.5. Billings Pro Server now supports iOS 7 and Mavericks; you’ll want to upgrade in advance of next week’s release of iOS 7 if you’re using Billings Pro Touch on iPhone or iPad. Billings Pro has some bug fixes and adds retainer history to statements and rounded time tokens to invoices; however, there doesn’t appear to be any documentation on those two features. Both offer some sync improvements.

Update 9/18/2013: Here’s what Marketcircle gave me on those new features:

• The tokens for rounded time are:

Slip’s Rounded Duration/Quantity: parent.reportData.object.quantityDurationRoundedString
Slip’s Rounded Decimal Duration/Quantity: parent.reportData.object.quantityDecimalDurationRoundedString

• For Retainers on statements:

Previously, if you generated a statement for a customer who gave you a retainer that you hadn’t invoiced yet, the statement would be blank. We used to only show invoices and payments on a statement. We now show the actual retainer payment made as well. This was added so that our customers could send a statement of account after receiving a retainer as a type of receipt for records.
