How to collect an unpaid drywall invoice

Short answer
Drywall invoices follow two completely different collection paths depending on who hired you. If you are working direct-to-homeowner, treat this like any residential trade: deposit, signed scope, and a day-3 call. If you are working as a subcontractor under a general contractor, the GC's cash flow controls your payment timing. Understand your state's prompt payment statutes and mechanic's lien rights -- most states give subcontractors the right to lien the property directly even when the GC hired them.

Connect your booksThe single most important question for drywall collection is: who is the actual client? A direct homeowner relationship gives you the most control -- you can call them, you can lien their property, and you can resolve disputes directly. A GC relationship means your payment is often contingent on the GC getting paid by the owner, which is a common practice but one that most state prompt payment laws are designed to protect against.
When working directly for homeowners, follow the standard residential trade approach: a deposit at scope agreement (typically 25-30% for a full room gut-and-hang), progress billing at drywall hang completion, and final payment at finish coat and prime. Photograph each stage, especially if you are working over existing framing that shows pre-existing damage or moisture. Mold or water damage discovered during a hang should be documented and a change order signed before you proceed.
When working under a GC, get your subcontract in writing and check whether the GC's contract contains a pay-when-paid or pay-if-paid clause. Most states treat pay-when-paid as a timing provision (you still get paid, just later) but treat pay-if-paid as a conditional payment that can be enforced. Know the difference before you start.
Mechanic's lien rights for subcontractors are state-specific and time-sensitive. In most states, you can lien the owner's property directly for unpaid work, even if the owner has already paid the GC. The preliminary notice requirements and deadlines vary by state, but the deadline from last day of work is typically 60-120 days. If you are a drywall sub working on larger commercial projects, tracking and filing preliminary notices should be part of your standard process, not an afterthought.
For day-to-day collection, place a friendly call on day 3 past due whether you are billing a homeowner or a GC. GC AP contacts are more responsive to calls than to email, and a quick check-in at day 3 often surfaces a missing lien waiver requirement or a PO number that is holding up the payment -- both of which you can resolve on the call.
