Waste Account Setup
When a build is rejected with material loss (total loss or partial recovery), Partsemble exports the cost of the lost materials to your accounting system. This export needs a designated account — your waste or scrap account — to record the expense against.
Why You Need a Waste Account
Without a waste account, Partsemble can't export rejected build losses. You'll still be able to reject builds with full recovery (since no waste needs to be exported), but rejections involving total loss or partial loss will be blocked until the account is configured.
Setting this up takes a minute and only needs to be done once.
Steps
1. Create the account in your accounting system (if needed)
If you don't already have a waste or scrap account, create one in QuickBooks Online (or your connected accounting system). Common account names include "Manufacturing Waste," "Production Scrap," or "Waste & Shrinkage." It should be an expense account.
2. Configure in Partsemble
Navigate to Settings → Integrations. In the Export Configuration section, find the Waste / Scrap Account dropdown. Select the account you created.
Click Save.
That's it. Partsemble now knows where to record material losses when rejected builds are exported.
What Gets Posted to the Waste Account
When a rejected build with loss is exported, Partsemble creates a transaction in your accounting system:
Total loss — the full cost of all consumed components is posted as an expense to the waste account. This is the entire material cost of the failed build.
Partial loss — only the cost of the lost portion is posted. Components that were recovered don't appear in the waste transaction.
The transaction includes a reference number (format: PSB-XXXXXXXX-W) that links back to the specific build in Partsemble, so you can always trace the expense back to its source.
When It's Required
| Rejection Scenario | Waste Account Required? |
|---|---|
| Full recovery (all materials returned) | No |
| Total loss (all materials lost) | Yes |
| Partial recovery with some loss | Yes |
| Partial recovery with no loss (all recovered) | No |
If you try to reject a build with loss and the waste account isn't configured, Partsemble shows a warning and disables the reject button. A link takes you directly to the integration settings to set it up.
Configure the waste account as soon as you enable QA review, even if you don't expect many rejections. It's one less thing to deal with when you actually need to reject a build for the first time.
