[Company Info](https://hub.acctivate.com/articles/configuration?hsLang=en#company-info) April 14, 2025 # Configuring Document Numbers for Sales, Purchasing, and Inventory Transactions ## File \> Configuration Management \> Company \> Numbers Document Numbers, such as the Sales Order number, are auto-assigned by Acctivate and defined in Configuration Management. To get here, go to **File \> Configuration Management \> Company \> Numbers**. For each Document Type, you must define the **Low** and **High** number.  The **Next** number will increment for each record and should be within the Low and High range. The administrative user can also define an alphanumeric **Prefix **and/or **Suffix **for each type of document except for Inventory session numbers.   ![Numbers](https://hub.acctivate.com/hs-fs/hubfs/Numbers.jpg?width=688&name=Numbers.jpg)   In the example above, the Order Number range of **A1200T – A2999T** would be used in the following configuration with **A1880T** as the next Sales Order number. When the **High** number has more digits than the next number, the Document Number will be padded with zeros.  For the Shipment numbering, the next number will read as **0100083** since the High number is 9999999 (7 digits) instead of 999999 (6 digits). The Documents listed about are found in the following sections of Acctivate: - Invoice – Sales Invoice, Service Invoice, and Credit Memo - Order – Sales Order, Service Order, and Credit Proof (Credit Memo before Releasing Credit) - PO – Purchase Orders - Issue – [Business Activities](https://help.acctivate.com/learn/businessactivity/) - Journal – General Journals - Package – Packages created in Packaging Manager - Shipment – Shipments created in Packaging Manager - Inventory – Inventory [Session numbers](https://hub.acctivate.com/articles/learn/inventory/whats-the-difference-between-inventory-session-and-transaction?hsLang=en) - Trace – [Track and Trace](https://hub.acctivate.com/articles/learn/inventory/how-do-i-use-an-inventory-track-and-trace-transaction?hsLang=en) - Picklist- [Picklist](https://hub.acctivate.com/articles/use-picklists-to-pick-orders?hsLang=en)ID.
