For subcontractors

# Invoice the GC on their schedule, and see what is still held back

A subcontractor bills a general contractor who pays on a cycle, holds back retainage and asks for the same paperwork every month. The work is finished long before the last of the money arrives, so knowing what is still owed matters as much as sending the invoice.

## The billing problems subcontractors actually have

The GC pays monthly against a pay application, and the cutoff date is strict.

Invoices can be drafted ahead and sent on the day, and a recurring schedule can raise the same monthly invoice on a fixed date without retyping it.

Retainage on your scope sits unpaid for months after you have left the site.

The retainage each invoice withheld stays on the job, so the amount still held back is one number, and the release invoice bills exactly that.

Chasing the GC’s accounts payable desk takes an afternoon a week.

Automatic reminders go out on the days after the due date that you choose, and each one links to the invoice and its payment page.

Sample work, priced the way this work is usually priced. The total is computed with the same function the console bills with.

## Questions

**Can I bill by square foot or linear foot?**

Yes. A line has a quantity and a unit price, so square feet, linear feet, hours and fixed items can sit on the same invoice.

**Can I see every invoice for one GC in one place?**

Yes. The client’s page lists their invoices, what each has paid, and what is still due, and you can send them a statement.

**Does BillingMart file lien notices for me?**

No. It bills and collects; it does not prepare or file lien notices or waivers.
