Managing & Adding Invoice Prefixes

Last updated: July 28, 2026

On this page

Invoice Prefixes allow you to organize different types of invoices by assigning them their own numbering series.

Each prefix maintains its own invoice sequence, making it easy to separate standard invoices, proforma invoices, reversal invoices, or any custom invoice series your organization requires.

Open the Invoice Prefixes settings

From the Enlivy dashboard, navigate to Settings → Accounting → Invoice Prefixes.

Here you’ll find the Invoice Prefixes dashboard. Every new Enlivy organization comes with three default invoice prefixes:

  • FACT- — Standard invoices
  • PROF- — Proforma invoices
  • STORNO- — Reversal invoices

You can use these default prefixes as they are or create your own custom invoice series.

Create a new Invoice Prefix

Click Add Invoice Prefix in the upper-right corner.

A popup window will appear where you can configure your new invoice prefix.

On the right side of the window, you’ll see a live Invoice Preview that updates automatically as you complete the fields, allowing you to immediately see how your invoices will look.

Complete the Invoice Prefix information

Name
The internal name of the invoice prefix. Choose a descriptive name that helps identify the invoice series — for example Services, Products, Consulting, or Subscriptions.
Alias
The prefix that will appear before the invoice number, such as SERV, PROD, or CONS. If the alias is SERV, your invoices will be numbered SERV1, SERV2, SERV3, and so on.
Type
Choose what type of documents this numbering series should generate. Standard is for regular invoices issued for products or services; Reversal is for invoices that cancel or reverse previously issued invoices; Proforma is for preliminary invoices or quotations that are not fiscal invoices.
Description
Optionally describe what this invoice series is used for. The description supports Markdown formatting.
Current Number
Defines the current number of the invoice sequence. The next invoice created with this prefix will use this value — for example, if the current number is 100, the next generated invoice will use that numbering sequence.
Has Custom Logo
Enable this option if invoices generated with this prefix should display a different logo than your organization's default branding. This is useful if your organization operates multiple brands under the same Enlivy account. The selected logo is immediately reflected in the Invoice Preview on the right.

Live Invoice Preview

As you modify the Alias, Type, Current Number, or Logo, the invoice preview updates in real time.

This allows you to verify exactly how invoices will appear before saving the new prefix.

Example

In this example we create a new invoice series for service invoices, using Services as the name, SERV as the alias, the Standard type, and 1 as the current number. The description reads:

We use this invoice prefix for our services invoices.

We’ve also enabled a Custom Logo, which is immediately visible in the invoice preview.

After reviewing the information, click Add Invoice Prefix.

Completed Add Invoice Prefix form.

Invoice Prefix created

Your new invoice prefix is now available.

Return to Settings → Accounting → Invoice Prefixes. You’ll see your newly created prefix alongside the three default invoice prefixes included with every Enlivy organization.

From this dashboard you can:

  • Create additional invoice prefixes
  • Edit existing prefixes
  • Delete custom prefixes
  • Manage multiple invoice numbering series for different document types
