This is the same arithmetic a general contractor uses to bill an owner, stripped to what a sub actually sends up the chain: your subcontract, your schedule of values, your retainage, and what the GC owes you this period. No architect's certificate, no owner block. Enter your line items and the document builds itself.
A sub's application gets rejected for a short list of reasons, and none of them are about the work. Knowing them is most of the job:
Retainage is the percentage the GC holds back from every application — commonly ten percent, often reduced part-way through the job, and released at or after completion. It is not a discount and it is not theirs; it is your money held as security. Two things worth knowing:
Most subcontracts make the GC's receipt of payment from the owner a condition of paying you, and the GC's own application to the owner has a cut-off date each month. An application that lands after that date does not wait a few days — it waits a full billing cycle. Ask for the GC's cut-off, bill to it, and date the application accordingly. It is the cheapest month of cash flow you will ever recover.
An application rarely travels alone. Depending on the subcontract, the GC is likely to want a conditional lien waiver for the amount being requested, unconditional waivers for amounts already paid, waivers from your own lower-tier subs and suppliers, and current certificates of insurance. Missing any one of them holds the payment regardless of whether the application itself is correct. There is a free lien waiver generator here too.
Many subcontracts are billed on AIA Document G702®/G703®, which are copyrighted forms licensed by The American Institute of Architects. This tool does not reproduce them. It produces an original document with the same figures in the same order. If your subcontract names the AIA form specifically, license it from AIA — a substitute will not satisfy a contract that names the form.

This generator produces an original application for payment and continuation sheet. It is not an AIA® document, is not affiliated with or endorsed by The American Institute of Architects, and does not reproduce AIA forms.
