E-billing systems reject invoices failing validation: incorrect LEDES format, unapproved timekeepers or rates, missing task codes, budget overruns without approval, or entries violating guideline rules.
Rejected invoices must be corrected and resubmitted.

Rejected Invoice, Invoice Return
Why it Matters?
Rejection delays payment by a full billing cycle or more, which is a cash flow issue distinct from the write-down question. Most rejections stem from preventable format and validation failures rather than substantive disputes, which means a firm reducing its rejection rate improves collection timing without any change to the underlying work. Tracking rejection reasons by cause identifies whether the problem is systemic or individual.
