Bill of Materials

← Back to Inventory

🔑 Who can see this: the Bill of Materials menu only appears if the Product Consumption feature is switched on for your account. If you'd like it, contact Invoay Support.

Every service uses up some product: a hair colour might use 60 ml of colour and 60 ml of developer; a facial uses a sachet of cream. Bill of Materials lets you tell Invoay how much product each service uses. Then, every time the service is billed, Invoay knows how much product was consumed.

This helps you:

  • see how much product your services really use,
  • spot waste, and
  • see your true profit per service on the Profitability Dashboard.

How to open it: Inventory › Bill of Materials

Consumption Setup​

Here you link each service to the products it uses.

  1. Click Add link in the list. A blank row opens at the top.
  2. Pick the Store Location.
  3. Under Service, choose the service (for example Hair Colour).
  4. Under Consumption Item, choose the product it uses (for example Colour Tube).
  5. In Consumption In Units, type how much of the product one service uses (for example 60).
  6. In UOM, choose the unit (ml, grams, pieces…).
  7. Click Save changes.

Repeat for each product a service uses: a hair colour that uses colour and developer needs two rows. To change a link, click a cell, change it and click Save changes.

Rows can't be deleted. To stop counting a link, untick Is Active and save. New rows always start active, so save first, then untick. If you see that the details already exist, that store already links the same service and product: change the amount on the existing row instead.

💡 Make sure your products have the right Unit of Measure in Item Master — if a bottle is measured in ml, enter consumption in ml too.

Consumption Summary​

A report of how much product was used, based on the services you billed.

Choose Date From and Date To (they open on the 1st of this month and today), then click Show consumption. You'll see the Store Location, Service Name, Bill Date, Product Used, Consumed Units (how much was used that day, added up) and the UOM.

  • Returned bills are left out.
  • Only active links are counted, including for past dates. If you untick a link in Consumption Setup, its rows leave this report.
  • The last row adds up every row showing, whatever the unit. Filter to one product or one unit first, so you're not adding ml to grams.
