Specifying the starting # for Auto Generated Invoice/Estimate numbers in BOOKS

Specifying the starting # for Auto Generated Invoice/Estimate numbers in BOOKS

I recently imported my data from Zoho Invoice to Books. All seemed to work well. ZohoBooks did NOT change my Invoice numbers Auto Generated by ZohoInvoice. But, now I would like to start Auto Generating the Invoice Numbers (and Estimate numbers) from WHERE I LEFT OFF with ZohoInvoice. But the first Invoice I created in Books was INV-1. I need it to be INV-134. How can I change this in ZohoBooks?
