Bill won't save: common causes

Bills sometimes refuse to save when required information is missing or invalid. This article walks you through the most common causes and how to fix them.

Symptom

You click the Save button on a bill form, but the page does not save and shows an error message or the form simply remains open.

Likely causes (ordered by probability)

1. Missing vendor Bills must be linked to a vendor (supplier). If no vendor is selected, the system cannot save.

• Fix: At the top of the bill form, select a vendor from the Vendor dropdown. If the vendor doesn't exist, create it first by going to Contacts → Vendors and adding them. Open in Usystems

2. Empty line items A bill with no line items cannot be saved. You must add at least one purchase line.

• Fix: Scroll to the Items section. Click Add Item, choose a product or service, enter the quantity and unit price, then save again.

3. Invalid quantity or price Line items with zero, negative, or non-numeric quantities/prices will block the save.

• Fix: Check each line item. Quantity and unit price must be positive numbers. Correct any invalid entries.

4. Missing payment account or bill account The bill cannot save if the system doesn't know which account to use for bills payable or if a payment method is not set up.

• Fix: This is usually a configuration issue. Contact your administrator to verify that the company's Bill Account (accounts payable) and Payment Account (cash/bank) are correctly set in company settings. Go to Settings → Company to check. Open in Usystems

5. Currency without exchange rate If the bill is in a currency other than your default, and no exchange rate is set for that date, the save will fail.

• Fix: At the top of the bill, set the currency. Then enter a valid exchange rate. If you're unsure of the rate, ask your finance team or check the date's official rate.

6. Duplicate bill number If you manually set a bill number that already exists in your system, the save will fail.

• Fix: Leave the bill number field blank and let the system auto-generate it. Or, use a unique number that has not been used before.

When to contact support

If you've checked all the above and the bill still won't save, or if you see a cryptic error message unrelated to the above, contact your administrator or Usystems support with a screenshot of the error.
