Purchase Orders vs. Requests: Which Approval Workflow Should You Use?

Quartzy supports two types of approvals:

We recommend starting with PO Approvals for spend management. You can layer on Request Approvals if your lab has specialized routing needs.

Note: PO Approvals are currently only available for organizations not integrated with QuickBooks Online or NetSuite. We're actively working to support these integrations — click here to join the waitlist.

Our Recommendation

Start with PO Approvals. They’re simpler to manage, align with how finance and purchasing teams operate, and give you full control over lab spend.

Use Request Approvals only if you need item-level checks that can't be handled at the PO level, such as:

  • When certain types of items (like hazardous chemicals) should be reviewed before ordering
  • When different budgets or grants require approval by their owners
  • When someone needs to confirm a specific item is correct or appropriate before it gets added to a PO

Request Approvals are useful when a specific person needs to sign off on what's being ordered. If you care about how much is being spent, PO Approvals are the better fit. 

Tip: PO Approvals are ideal for startups and enterprise labs managing centralized purchasing workflows. Universities may prefer Request Approvals since requisitions and PO generation often happen outside of Quartzy, through a separate procurement system.


Tips

  • Set auto-approval thresholds to avoid manual review of low-cost items.
  • Keep it simple at first. It's easier to layer on complexity than to untangle a web of unnecessary rules later.
  • Use the PO List View and Requests tab to stay on top of what's waiting for approval.
  • Double-check your notification settings to make sure the right folks are getting the right emails.
