Invoice goods and services as line items.
Catalog → Products / Services holds goods (optionally tracked) and services. There is no composite/bundle SKU that automatically consumes component stock. Put each line you sell on the invoice or estimate.
What you actually set up.
Products and services, not a manufacturing BOM.
Goods
Tracked products move inventory when invoiced or billed.
Services
Non-stock lines for labour, retainers and fees.
Invoice lines
Add as many products or services as you need on an estimate or invoice.
Simple catalogue, accurate books.
No phantom assemblies
You will not sell a bundle SKU that the stock engine cannot explode.
Clear COGS
FIFO / WAC applies to tracked goods you actually invoice.
Estimates first
Quote a mix of goods and services, then convert to invoice in one click.
Common questions
Can I sell a kit that deducts three components?
Not as an automatic BOM. Create the three products and add three lines, or invoice a single service/goods line if you do not track components.
Can I mix goods and services on one invoice?
Yes. That is the usual UK job invoice.
Do services affect inventory?
No. Only products with track inventory reduce or increase on-hand.
Where do I create items?
Catalog → Products / Services in the admin sidebar.
Sell what you listed. Stock what you track.
Business and above include inventory valuation. Solo is invoicing, bank import and expenses without the stock engine.
