Invoice Field Reference

This page documents every field on the invoice editor, grouped by the section it appears in. Use it as a lookup while building a document. For a step-by-step walkthrough instead, see Create or Edit an Invoice.

Fatorly validates each document against the UAE PINT (PINT AE) rules before it can be submitted. Fields marked Required must be present; several others are conditionally required depending on the tax category, document type, or whether you start filling a related group.

The editor is organized into a header, a line-items table, four collapsible sections (Transaction Type, Charges & Allowances, References & Delivery, Payment & Notes), and a live Totals panel.

Invoice editor with the Charges & Allowances and References & Delivery sections expanded

1. Document header (Invoice Details)

VAT Point Date	Optional	Date picker	—	The date on which VAT becomes due, if different from the issue date (BT-7). Must fall before the issue date. Not allowed on credit notes.

Supplier fields (from Company Profile)

The following supplier field is configured once in Settings → Company Configuration → General and is automatically emitted on every invoice you create.

Field	Required	Control	Notes

2. Counterparty & credit-note reference

Field	Required	Control	Allowed / default	Notes
Customer / Vendor	Expected	Searchable dropdown	From your Customers / Vendors	The buyer (sales) or supplier (purchase / self-billing). Selecting one fills its name, TRN, and address.

A Tax Invoice requires a counterparty that has a VAT TRN. A Commercial Invoice is for counterparties without a TRN. The customer/vendor list is filtered accordingly.

3. Transaction Type (UAE special scenarios)

UAE VAT law (FTA PINT-AE code BTAE-02) recognises eight special invoice scenarios. Use the collapsible Transaction Type section to select the ones that apply. Each scenario tags the invoice and reveals the extra fields it legally requires. Leave the section empty for a standard tax invoice; more than one scenario can apply simultaneously.
