We use third party software to import purchase invoices to Sage via a sync and this is working very well.

This week, the software refused to post an invoice to Sage as it was dated prior to the lock date set after closing the quarterly Management Accounts.

The software is set up as a Full Access User on Sage, but will not be able to override the lock date as I would be able to.

Any suggestions, please - apart from posting the invoice manually?

Thanks
