Overview
Invoice numbers in Lever360 must be unique across the entire system — across every job and every location. When you try to create an invoice using a number that has already been used, Lever360 prevents the duplicate and displays an error. This article walks through the error and the two ways to resolve it.

Why This Happens
When you create an invoice with a number that already exists in the system, you'll see this message at the top of the invoice:
Invoice with same number already exists. |
Invoice numbers are unique across the entire Lever360 system — they are not scoped to a single job or location. This ensures clean accounting handoffs and prevents duplicate records downstream in QuickBooks and your reporting. There are two ways to resolve the error depending on whether you want a one-time fix or a long-term correction to your numbering sequence.
How to Fix It
Option 1 — Override the Invoice Number (Quick Fix)
Use this option when the duplicate is a one-off and you just need to move past it.
1. On the invoice showing the error, locate the Invoice Number field.
2. Modify the number to the next available number in your sequence (for example, if 1483 was a duplicate, change it to 1484).
3. Click Create Invoice. The invoice will save successfully and the error will clear.
💡 Tip. If you're not sure what number to use, check your most recent invoice across the system and pick the next number up from there. |
Option 2 — Update the Next Invoice Number Sequence (Long-Term Fix)
Use this option if your numbering is off across the system — for example, if you've created several manual invoices, are just getting started in Lever360, or want to skip ahead to a cleaner starting number. This resets where the system will pick up for all future invoices.
1. From the main menu at the bottom, click the Settings gear icon.
2. Open Company Settings.
3. Scroll to the Job Information settings group.
4. Locate the Next Invoice Number field and update it to your desired starting number (for example, 1500).
5. Click Save.
From this point forward, every new invoice created in Lever360 will start from the new sequence number and increment from there.
IMPORTANT: Always set the next invoice number ahead of your last used number. Setting it backward into a range you've already used will cause duplicate errors again. |
