Your administrator adds the field you need to contacts, orders, tasks, or employee records without writing code. It shows on the form and the detail page, and as a list column and filter if you choose.
Runs in your browser. In the cloud or on your own server, it's the same IWB.

Build your own lists without exporting to Excel
You don't need to export records to Excel to list them by a detail only your business tracks. A field you add is offered as a list column, and you can add it to the filter menu and to sorting too. Formula fields become columns as well, and you can filter by their results.
Formulas that depend on today are recalculated every night
When you change a formula, existing records are recalculated too
Save the filter as a view and share it with your team

Details from the quote follow it to the invoice
Nobody retypes the sales channel picked on the quote when the order and invoice are created. When a field has the same key, type, and options on the quote, order, and invoice, its value moves to the next document on conversion. You can also add details you learn after the invoice is issued, and the amounts and document number stay the same.
Purchasing carries values across requisitions, orders, and purchase invoices too
An RMA (return merchandise authorization) opened from a service order takes the values of the same fields
The new document recalculates formula fields with its own formula
Confirmed orders and posted purchase invoices also keep their custom fields editable

Keep sensitive employee details out of sight
Keep payroll and attendance card numbers on the employee record without showing them to everyone. A new field on employee records starts as sensitive: only people you give a separate permission can see and edit the field and its value. For everyone else, the field does not exist on the record, in lists, in filters, or in reports.
Removing the sensitive mark requires the same permission
IWB AI and Excel exports don't show the field to users without the permission
The field list marks sensitive fields with a badge
The settings page reminds you to collect special-category data, such as health details, only with a legal basis
Choose from 17 types, such as money, date, choice list, and formula. Each type tile explains in a few words what it is for.
Help while you write formulas
Type [ to open the field list, and typing an Excel name such as concatenate suggests the matching function. Errors are marked as you type, with a suggested fix next to them.
Ready-made examples
Start from 9 examples, such as "Calculate a percentage," "Days until a date," and "Label by condition." Then pick your fields for the dashed placeholders.
Required fields and rules
Make a field required and give it a default value. Set minimum and maximum values for numbers, and length limits and a format pattern for text.
Color-coded options
Give each option in a choice list a color, and paste a list to add options in bulk. Deactivate an option in use instead of deleting it.
Change history
See changes to choice, number, and date fields in the record timeline, with old and new values.
In reports and Excel
Filter contact, product, task, and CRM reports by a custom field, and group them by single-select and yes/no fields. When you export a list to Excel, custom fields become their own columns.
IWB AI fills them in
When IWB AI creates or updates a record, it fills in custom fields too. It shows you what it will write before saving, and you approve it.
You can add custom fields to 35 record types. The list starts with contacts, products, leads, and opportunities. Sales and purchasing documents, tasks, and projects are on it too. So are contracts, support tickets, and employee records. Field Service, Finance, Laboratory, and Manufacturing records take custom fields as well.
Can I change a field after creating it?
You can change its name, description, and rules at any time. You can also add options, rename or recolor them, and deactivate an option in use. The type and key can't change once the field is created. For a field that already has values in records, the currency of a money field and the target of a relation field stay fixed too.
How do we remove a field we no longer use?
Delete a field that has no values in any record. Deactivate a field that has values: it disappears from forms, lists, and filters, records keep their values, and you can turn it back on later. If you also have the permanent delete permission, you can delete a field together with its values, which can't be undone.
Do custom fields show on printed invoices and e-Invoices?
Custom fields are for your company's internal tracking: they stay off printed documents, e-Invoices, and accounting entries. Updating a custom field on an issued invoice doesn't change the official document.
Which fields can be marked sensitive?
The sensitive (personal data) mark is available on employee record fields, and new fields there start as sensitive. A sensitive field can't be required or have a default value, because users who can't see it still need to save the record.
