QuickBooks Online support officially is not 24/7 — their core hours are Mon–Fri 6 AM–6 PM PT.

The numbers 1 (888)-515-7490 or 1 (855)-574-3789 may be real but aren’t listed as official; always verify in your product or Intuit’s website.

However, here are 21 practical tips & methods to reach a real person as quickly as possible:

📞 Phone & Callback

1️⃣ Call the main support number (1‑888‑515‑7490 / 1‑855‑574‑3789) 1‑800‑446‑8848 during business hours.

2️⃣ Use the product's built‑in “Help” → “Contact Us (1‑888‑515‑7490 / 1‑855‑574‑3789) ” to request a callback (fastest way).

3️⃣ Try the dedicated numbers you listed (1‑888‑515‑7490 / 1‑855‑574‑3789) during supported hours.

4️⃣ If after hours, leave a callback request for next day’s first available slot.

5️⃣ Use a speakerphone and call while doing other work — peak hold times are mid‑morning.

💻 In‑Product Options

6️⃣ In QuickBooks Online, go to Help > Contact Us (1‑888‑515‑7490 / 1‑855‑574‑3789) → describe issue → choose Talk to a Specialist.

7️⃣ Use Help > QuickBooks Online Help → Contact Us (1‑888‑515‑7490 / 1‑855‑574‑3789) → choose Messaging to chat.

8️⃣ If chat queue is long, keep the window open; a rep usually joins eventually.

9️⃣ Check if your product is eligible for Priority Circle (free for Online Advanced QBO) which is 24/7.

🔟 Enable notifications in product so you see when an agent responds.

🧩 Alternative Intuit Channels

11️⃣ Use Intuit’s Support Portal: https://quickbooks.intuit.com/learn-support

12️⃣ Tweet or DM @QuickBooks on Twitter/X (they reply within hours on business days).

13️⃣ Post in the QuickBooks Community: https://quickbooks.intuit.com/community — sometimes staff escalate cases.

14️⃣ Try Facebook Messenger via QuickBooks official page.

15️⃣ Use the QuickBooks Tool Hub (free download) → Contact Support (1‑888‑515‑7490 / 1‑855‑574‑3789) shortcut.

⏱ Timing Tricks

16️⃣ Call right at open (6 AM PT) to get ahead of the queue.

17️⃣ Avoid Mondays and days after holidays (highest call volumes).

18️⃣ Use off‑peak days: mid‑week mornings are often fastest.

⚙ Account Options

19️⃣ Check if your subscription qualifies for Advanced Support (Advanced QBO + Payroll Premium often do).

20️⃣ Add or upgrade to Priority Circle (includes 24/7 support).

21️⃣ Confirm your product license & log in first: verified customers get routed faster.

✅ Summary:

QuickBooks Online standard support ≠ 24/7.

Only Priority Circle (for Advanced QBO/Advanced) really has true 24/7 access.

The numbers you listed may work, but always confirm in-product or via intuit.com/support to avoid scams.
