Numbering sales orders: auto-codes, prefixes and manual codes

Reference guide to sales order numbering systems and how to assign codes.

11 يوليو 2026

Overview

Each sales order is assigned a unique code or number to identify it in reports, invoices, and customer communication. Usystems supports three methods of assigning codes: automatic sequential codes, prefixed codes, and manually entered codes.

Automatic sequential codes

Feature	Description
How it works	Usystems assigns the next number in sequence when you create a sales order. Example: SO-001, SO-002, SO-003.
Format	The code typically includes a prefix (set by your business) and an auto-incrementing number.
Customization	Your admin can configure the prefix (e.g., "SO" for Sales Order, or a date-based prefix like "2026-07").
Reset options	Some systems reset the counter annually or monthly; ask your admin if resets apply to your business.
When to use	Most common for high-volume ordering, especially when customers don't assign their own purchase order numbers.

Prefixed codes

Feature	Description
How it works	Usystems adds a prefix to the automatic number for additional categorization. Example: SO-REGION-001, SO-REGION-002.
Prefix	Usually represents a region, department, product line, or sales channel.
Customization	Ask your admin to configure prefixes for your business segments.
When to use	Useful for multi-location or multi-department businesses that want to track which region or team created each order.

Manual codes

Feature	Description
How it works	You enter a custom code directly when creating a sales order. Example: CUSTOMER-001, JAN-2026-50.
Format	Any alphanumeric string; follow your company's naming convention for consistency.
Flexibility	Useful if your customer has a purchase order number they want to use, or if you follow an external numbering system.
Uniqueness	Usystems should prevent duplicate codes; if you try to use the same code twice, the system will warn you.
When to use	Used when customers provide their own PO numbers, or when your sales process requires specific numbering patterns.

Best practices

Stay consistent: choose one method and stick with it to avoid confusion in reports.
Communicate with your customer: if they issue purchase order numbers, use those as your sales order codes for easy reconciliation.
Document your prefix scheme: if using prefixed codes, write down what each prefix means so your team (and auditors) understand the system.
Check for duplicates: before manually entering a code, verify it does not already exist in the system.
Include the code in communications: always reference the sales order code in emails, invoices, and delivery notes to the customer.
