Products
Updated 31 October 2026
Products are the goods and services you sell and buy. Using products on invoices makes them quicker and more accurate, because each product brings its own nominal code, VAT code and price. A product can be used for sales, purchases or both.
Open products from the Products tab in the Aedon.Sales or Aedon.Purchases app.

Product information(1)
- Product Name and Product Code: you can search for either on transactions.
- Product Description: for internal use.
- External Product Description: printed on your sales documents.
- Product Family: groups products for reporting.
- Product Type: Sales, Purchases or Sales & Purchases.
- Company and Active: only active products can be chosen on transactions.
Cost and price(2)
Enter the Standard Cost, Purchase Price and Standard Price without VAT. The prices are used as the default unit price on new lines. If you enter a Standard Cost, you can report a standard gross profit on your sales.
Default nominal codes(3)
The Sales Nominal Code and Purchase Nominal Code are used when the product is added to a sales or purchase transaction.
Tax treatments and tax codes(4)
The Tax Treatment & Tax Codes table sets the VAT code for each product type and tax treatment, for example UK and overseas customers. See Default Product Tax Codes.
Create a product
- On the Products tab, click New.
- Enter the Product Name and any other product information. Make sure Active is ticked.
- Enter the cost and prices, and the default nominal codes.
- Click Save.

Overheads products
Create an Overheads product family for regular costs such as rent, stationery, software and bank charges. Each one then brings the right nominal and VAT codes to your purchase invoices.
