Custom fields let you track extra information about your Products, Orders, or Ship Advice that Acenda doesn't capture out of the box — things like material, battery count, a gift message, or any marketplace attribute that doesn't have a home yet. Once a field exists, you can fill it in on an item, through an import, or map it into a channel's Posting Template.

Step 1: Create a single custom field

Navigate to Custom Fields: In the sidebar, under CATALOG, click Custom Fields.
Choose the model: You'll see three rows — Product, Order, and Ship Advice — each showing how many fields it has. Click Edit next to the one that needs the new field. This opens that model's custom fields page (for example, Product Custom Fields), which lists each field's name, validation type, and actions.
Click Add Field in the top right. (Add Bulk sits next to it.)
In the Add Field dialog, fill in:
- Name: Type a descriptive name, such as material type. Acenda cleans this up automatically — lowercasing it and swapping spaces and special characters for underscores — and shows you exactly what will be saved (Will be saved as: material_type) as you type.
- Tip: If you're creating this field to map a Posting Template attribute, name it to match that attribute so it's easy to find later. If you only need a different value on one specific channel rather than everywhere, a CATALOG > Attribute Overrides entry may be a better fit than a new field — see how to find the allowed values for a marketplace field for matching channel-specific values.
- Validation Type: Choose the kind of data this field holds:
  - Text:Single Line Text Field (most attributes) or Multi Line Text Field (when you need line breaks).
  - Numbers:Number Integer or Number Decimal.
  - Yes/No:Boolean.
  - Dates:Date or Date Time.
  - Measurements:Weight, Volume, or Dimension — each stores a number plus a unit (for example, 4 lb).
  - Other:Color or URL.
- Description: (Optional) A short note for your team on what the field is for.
Click Add to save.

Custom fields can't be edited after creation. To change a field, delete it and create a new one. Each field on the model's page has a Delete button, so double-check the name and Validation Type before you click Add.

Heads up — two naming rules:

The cleaned name still needs a letter or number. As you type, Acenda lowercases the name and turns spaces and special characters into underscores (see Will be saved as:). That cleaned version must include at least one letter or number. A name made only of symbols (for example !!!) won't save, and Acenda will ask you to change it.
Names must be unique on that model. Product, Order, and Ship Advice each keep their own list of custom fields. If the cleaned name is already used on the model you're editing, Acenda suggests a suffix such as _v2 so you can pick a unique name.

Step 2: Add custom fields in bulk

Creating several fields on the same model at once? Use the bulk tool instead of adding them one at a time.

On the Custom Fields page, click Edit next to the relevant model.
Click Add Bulk in the top right.
Add your field names. You can:
- Paste a comma-, tab-, or newline-separated list, such as from a spreadsheet column.
- Type names one at a time, pressing Enter or comma after each to turn it into a chip.
Choose one Validation Type — it applies to every field in the list, so group fields of the same data type together.
Click Add to finish.

Where custom fields show up afterward

Once created, a custom field is available everywhere in your account right away:

On the item itself: Open the item under CATALOG > Items and look in the Additional Attributes section of its details, below the Media section — every custom field for that model appears there, ready to fill in.
In imports: Add a column named fields.<name> (for example fields.material_type) to an .xlsx or .csv import. Weight, Volume, and Dimension fields split into two columns instead — fields.<name>.value and fields.<name>.unit.
In Posting Templates: Map the custom field to a channel attribute when building a Posting Template, so its value flows out to the marketplace.

Important: In an Overwrite-mode import, leaving a fields.<name> cell blank clears that custom field on the item. To leave an existing value untouched, remove the column entirely rather than leaving the cell empty.

Troubleshooting

"Field name must contain at least one letter or number": Your typed name was made up entirely of spaces or symbols that get stripped during clean-up. Add a letter or number.
"Field already exists": That name is already used on this model. Pick a more specific name or add a suffix like _v2.
I need to change a field I already created: Custom fields can't be edited after creation. Delete the field and create a new one with the right name or Validation Type. Deleting a field removes it from the model's list, so check first whether imports or Posting Templates still use it.
I don't see the model I need (Image, Fulfillment, etc.): Only Product, Order, and Ship Advice are available from this page today. Contact Acenda Support if you need a custom field on another area.
A new field isn't showing up on an import template or the item page yet: It can take a short time to appear everywhere in the account. Refresh the page, and if it's still missing after a few minutes, reach out to support.
An import rejected my fields.* column: Check that you're using fields.<name> exactly, and for Weight/Volume/Dimension fields, that you're using the .value and .unit suffixes rather than a single bare column.

Still stuck? Contact Acenda Support and let us know the model (Product, Order, or Ship Advice) and the field name you're working with.
