Overview
Transaction types in Found let you label invoice line items as either a Credit or Debit, based on whether the transaction amount is positive or negative. Rather than maintaining a list of codes, Found uses two workspace-wide labels — one for credit transactions and one for debit transactions — which are applied automatically to every invoice line item based on the sign of the amount. By default, both fields are left blank.
This article explains what transaction types are, where to find the setting, how to configure them, and what rules and permissions apply.
What is a transaction type?
A transaction type is a label shown against an invoice line item to describe whether the line is a credit or a debit. In Found, transaction types are configured per workspace and consist of two values:
Label for credit transactions — shown for line items with an amount of zero or greater (for example, "SI").
Label for debit transactions — shown for line items with a negative amount (for example, "SC").
Once configured, the label is derived automatically from the amount on each invoice line item. You do not assign a transaction type manually when adding a line — Found applies it based on whether the value is positive or negative.
How to create or update transaction types
Navigate to Settings → Billing → Transaction types.
Enter a label in the Label for credit transactions field (up to 64 characters).
Enter a label in the Label for debit transactions field (up to 64 characters).
Save the form.
Once saved, the labels apply to invoice line items the next time they are loaded. Previously listed invoices will also display the updated labels, since the value is computed at read time rather than stored on each line item.
To clear a label, leave the field empty and save — the underlying value is cleared and invoice line items will display no transaction type until a new label is entered.
How it works
Found stores the two labels against the workspace's invoice settings.
When an invoice is loaded, each line item is enriched with a transaction type value:
If the line item amount is zero or greater, the credit label is shown.
If the line item amount is negative, the debit label is shown.
If a label has not been set, the transaction type on the line item will be blank.
The Transaction type column on the invoice items table is hidden by default. You can enable it from the table's column picker.
Rules
Each label is optional, but if entered must be between 1 and 64 characters.
Leading and trailing whitespace is trimmed automatically.
Empty strings are not accepted — leave a field blank to clear the value.
Labels are workspace-wide; you cannot define different labels per invoice or per customer.
There is no list of multiple transaction types — only the credit and debit labels exist.
Frequently asked questions
Q: Can I create more than two transaction types? A: No. Found uses a single credit label and a single debit label per workspace. The transaction type displayed on each line item is derived from the sign of the amount.
Q: Do I need to assign a transaction type when adding an invoice line item? A: No. The label is applied automatically based on whether the line item amount is positive or negative.
Q: Will updating the labels change historical invoices? A: Yes. The transaction type is computed when invoices are loaded, so changing the labels updates the display on existing invoices as well as new ones.
Q: Can different customers or invoices use different transaction types? A: No. The labels are workspace-wide and apply to every invoice in the workspace.
Q: Why can't I see the Transaction types page? A: Either the Transaction types feature flag is not enabled for your workspace, or you do not have access to billing settings. Check with your Found administrator.
Q: Why can I see the page but not save changes? A: You need the admin role to edit transaction type labels. Managers and staff have read-only access.
Q: What happens if I leave a label blank? A: Invoice line items in that category (credit or debit) will display no transaction type. You can set the label at any time and the display will update.
Q: Is there a character limit? A: Yes — each label can be up to 64 characters.
Q: Where does the transaction type show up on an invoice? A: It appears as the Transaction type column on the invoice items table. The column is hidden by default; enable it from the table's column picker.
Q: Can I delete a transaction type? A: There is nothing to delete — transaction types are settings, not records. Clearing the label (leaving the field blank and saving) removes the value from invoice line items.
