The short version
Clerk Invoices is the better fit if you're already deep in the Atlassian ecosystem, bill per-instance rather than per-agency, and want invoices synced automatically into Xero or QuickBooks. WorklogPDF is the better fit if you want a fast, standalone tool that one person on the team can use to generate an invoice without touching Jira admin settings, and you'd rather pay a flat monthly fee than a per-seat one.

Where Clerk Invoices wins
Choose Clerk Invoices if:
- You want invoicing embedded in Jira rather than a separate tool
- Automated Xero or QuickBooks sync matters more than a fast one-off PDF
- Your whole team, not just one person, needs to interact with invoicing
- You value an established track record — it has 411 installs and a 5/5 rating on the Atlassian Marketplace
Choose WorklogPDF if:
- One person handles invoicing and doesn't need Jira admin access to do it
- Your team is 5–20 people and per-user pricing adds up fast
- You want a client-ready PDF in under a minute, without configuring an app inside Jira
- You'd rather pay a flat fee than a per-seat one that scales with headcount
The pricing math, worked through
Per-user pricing sounds reasonable until you actually run the numbers for a growing agency. Here's a rough comparison across team sizes:
| Team size | Clerk Invoices | WorklogPDF |
|---|---|---|
| 5 people | Scales with per-user pricing | $19/month |
| 10 people | Scales with per-user pricing | $19/month |
| 20 people | Scales with per-user pricing | $19/month |
Check Clerk Invoices' current per-user rate on the Atlassian Marketplace listing for an exact figure for your team size — but the structural point holds regardless of the exact number: a flat fee doesn't move when you hire.
What neither tool does well (yet)
Worth being upfront about the gaps. Clerk Invoices' invoicing lives inside Jira's interface, which some non-technical stakeholders find clunky compared to a plain PDF. WorklogPDF, being newer, doesn't yet offer direct accounting software sync — you'll be exporting a PDF and handling the bookkeeping step yourself, or handing it to whoever manages your books.

Is WorklogPDF a Jira plugin like Clerk Invoices?
No. WorklogPDF is a standalone web app that connects to Jira via OAuth to read your worklogs. Clerk Invoices installs directly inside Jira as an Atlassian Marketplace app. Neither approach is objectively better — it depends on whether you want the tool living inside Jira or as a separate step in your billing workflow.
Which is cheaper, Clerk Invoices or WorklogPDF?
It depends on your team size. Clerk Invoices charges per user, so cost scales with your Jira instance. WorklogPDF charges a flat $19/month regardless of how many people are in your Jira. For agencies of 5 or more people, the flat-rate model is usually cheaper.
Does WorklogPDF sync with Xero or QuickBooks?
Not currently. WorklogPDF generates a client-ready PDF invoice from your Jira worklogs, which you then import or re-key into your accounting software. Clerk Invoices offers direct QuickBooks and Xero sync, which may matter more if you need automated bookkeeping rather than a fast, simple invoice.
