Custom Fields
Add your own fields to invoices, quotations, vendor bills and items in Sayl Finance.
Try it in the live demoFinance → Accounting → Custom Fields
What it is for
Custom fields are extra boxes on your own documents - a PO number on invoices, a cost centre on bills, an SLA tier on items - so you can record what matters to you without waiting for a feature.
How it works
- Fields are added per document type: Invoices, Quotations, Vendor bills and Items.
- The key is fixed once created (letters, digits and underscores) because the API uses it.
- Turning a field off hides it without losing what was already recorded.
