What Is Deltek Costpoint?

What’s going on with Deltek Costpoint?

Think of it as your one-stop shop for project billing, revenue recognition, expense tracking, labor cost visibility, and staying DCAA-compliant. It bundles time entry, expense reports, budgeting, and real-time financial controls into one tidy interface. When timesheets refuse to save or start throwing errors, nine times out of ten it’s a browser hiccup, a session timeout, or a sneaky data conflict hiding in the Costpoint database.

How do I fix a Costpoint timesheet that won’t save?

Start with the basics:

1. Sign in the right way (2026 edition)
   • Fire up your browser and punch in https://yourcompany.costpoint.com—swap in your real Costpoint URL.
   • Stick to supported browsers: Chrome 120+, Edge 120+, or Firefox 115+. Anything older is basically asking for trouble.
   • Type your Login ID (usually your email or employee ID), password, and company domain. Hit Submit.
2. Open the timesheet
   • Drill down to Time & Expense > Time > Timesheet > Manage Timesheets.
   • If the current period’s sheet is AWOL, click New in the header.
   • Pick your period-ending date by clicking the calendar icon next to Period Ending.
3. Edit or reset the timesheet
   • In the header, click Correct. The Timesheet Lines table lights up and becomes editable.
   • Make your tweaks—add hours, switch projects, whatever you need. Made a mistake? Hit Undo Correct.
   • When you’re done, click Save to lock it in.

I tried the steps—timesheet still won’t save. Now what?

• Refresh the browser and clear the junk:
  • Close the browser, nuke the cache with Ctrl+Shift+Del (Windows) or Cmd+Shift+Del (Mac), and tick “Cookies and other site data” plus “Cached images and files.”
  • If things still feel sluggish, reboot your machine—sometimes that’s all it takes.
• Go incognito to dodge cached gremlins:
  • Open a Private/Incognito window (Ctrl+Shift+N or Cmd+Shift+N).
  • Log back in and try the timesheet again. This route skips past any corrupted local data.
• Double-check your user rights:
  • Make sure your Costpoint account hasn’t lost permissions. If the timesheet options look missing, ping your Deltek admin.
  • Check that your account isn’t locked or expired. Admins can fix this under System Admin > User Management.

Any tips to keep timesheet problems from coming back?

• Stick to supported browsers
  • Always run the latest Chrome, Edge, or Firefox. Anything older—especially Internet Explorer—is basically begging for errors.
  • Turn on automatic updates so you’re never stuck on a broken version.
• Save early, save often
  • Hit Save every 5–10 minutes while you type. Costpoint’s session can time out after 30 minutes of idle time.
  • Don’t leave the timesheet open in the background all day—close it when you’re done.
• Keep your gear updated
  • Run current OS patches and antivirus scans to prevent compatibility gremlins.
  • Turn off browser extensions that might gum up form submissions.
• Train your team on the right moves
  • Make sure everyone knows how to use Correct and Undo Correct so they don’t accidentally corrupt data.
  • Schedule yearly refresher sessions for any new Costpoint features released since 2024.

If the problem refuses to die, loop in your Deltek admin or dig into the Deltek Support Knowledge Base, which gets fresh updates every quarter with known bugs and patches. As of 2026, Deltek still backs both on-premise and cloud setups with regular security and feature upgrades.
