All Invoices, Stock Orders, Supplier Payments, Customer Payments and Customer Credits are assigned a unique identifying Number in Workshop Software.
This article explains how to adjust Workshop Software's settings to continue allocating these Numbers from a new value.
Please Note: The new value chosen for any Number must be higher than the previous value. This limitation prevents the creation of duplicate Invoice and Payment numbers that may cause sync conflicts with Accounting Packages like Xero or MYOB.
