PTP Accounts Production
Xero API – Trial Balance Import
We have updated how the software connects to the Xero API to allow you to continue importing Trial Balance information.
Flysheet Formatting – Left Margin Justification Option
We have added a new configuration option to enable left margin justification for flysheet title output, providing greater flexibility in document formatting.
The left margin justification option can be configured through the flysheet settings in report options, giving users control over the final document appearance without affecting data integrity or content.
PTP Share Register
