How to automate construction draw requests and pay apps

What goes into a draw request

A draw request is the monthly package a contractor submits to get paid for work completed, usually built around the AIA G702 and G703 forms plus supporting documents. The exact contents depend on your contract and, on financed projects, on the lender's draw requirements.

A typical package includes:

• G702, Application and Certificate for Payment. The one-page summary: original contract sum, net change by change orders, contract sum to date, total completed and stored to date, retainage, total earned less retainage, previous certificates for payment, current payment due and balance to finish.
• G703, Continuation Sheet. The line-by-line breakdown of the schedule of values. For each line: scheduled value, work completed from previous applications, work completed this period, materials presently stored, total completed and stored to date, percent complete, balance to finish and retainage.
• Lien waivers. A lien waiver is a signed document in which a contractor, subcontractor or supplier gives up lien rights for amounts paid. Draws usually require conditional waivers for the current payment and unconditional waivers for the previous one, from you and often from every sub and major supplier. Several states require specific statutory waiver forms, so check your state's rules.
• Backup. Subcontractor pay apps, supplier invoices, proof of stored materials (photos, bills of lading, insurance certificates), approved change orders and sometimes certified payroll on public work.
• Lender or owner extras. Notarized signatures, a sworn statement listing subs and amounts, inspection sign-off, or title updates, depending on the project.

The terms "pay app" and "draw request" are often used interchangeably. In practice, the pay app is the G702/G703, and the draw is the full package that goes to a lender.

Why draw requests eat so many hours

Draw requests are slow because the information lives in four or five places and has to agree perfectly. The math itself is simple; reconciling the sources is not.

On a typical month, a project manager or project accountant:

• Exports job cost and committed cost reports from the accounting system.
• Walks or calls the field to update percent complete by line item.
• Checks which change orders are fully executed and can be billed, and which are still pending.
• Collects sub pay apps, then compares each sub's billing to their own schedule of values and to what you are billing the owner.
• Requests, chases, receives and checks lien waivers for amount, date, project name and correct form.
• Rebuilds or updates the G703 spreadsheet, rolls it to the G702, and ties the totals back to the previous application.
• Fixes the inevitable rejection: a waiver with the wrong amount, a stored material without backup, a line billed over 100 percent.

None of that is hard. It is repetitive, it has to be exact, and it lands at the same time every month for every active job. That combination is what makes it a good target for workflow automation.

Which steps to automate, and which to keep human

Automate the collection, matching and math. Keep people on field progress, billing strategy and anything that needs a signature or a relationship.

Step	Automate?	Why
Pull job cost, commitments and previous billing	Yes	Same reports, same fields, every month
Roll forward the G703 and calculate G702	Yes	Pure arithmetic once inputs are known
Flag change orders that are approved vs. pending	Yes	Status check against a log
Request and chase lien waivers	Yes	Templated messages on a schedule
Check each waiver for amount, dates, parties and form	Yes, with review of exceptions	Document reading and matching; mismatches go to a person
Compare sub pay apps to their schedule of values	Yes, with review of exceptions	Overbilling and math errors are easy to detect
Set percent complete by line	Suggest only	Needs someone who knows what is built
Decide what to bill (front-loading, stored materials, retainage release)	No	Commercial judgment and contract terms
Sign, notarize and submit	No	Legal attestation by an authorized person

This split is what people mean by human-in-the-loop: the system does the assembly and brings a person only the exceptions and the final approval.

How to automate draw requests, step by step

Start with your data structure, then automate one job's draw end to end before rolling it out. Trying to automate every job at once is the most common way these projects stall.

1. Standardize the schedule of values. Use consistent line items and cost codes that map cleanly to your accounting system. If each PM invents their own structure, an automation has nothing stable to hold onto.
2. Pick one source of truth for each input. Decide where contract values, change order status, previous billings and sub commitments officially live. Write it down.
3. Build a change order log with a status field. "Executed," "pending owner signature," and "disputed" should be explicit, so the system bills only what is approved.
4. Set up a waiver tracker. One row per sub or supplier per draw, with amount, waiver type (conditional or unconditional, progress or final), date requested, date received and status.
5. Automate the chase. On a set day each month, send each sub a request with the exact amount and the correct form. Follow up automatically until it arrives. Escalate to the PM after a set number of days.
6. Automate the match. When a waiver or sub pay app arrives, read it, compare it against the tracker and the commitment, and flag anything that doesn't tie: wrong amount, wrong through-date, wrong project, missing signature.
7. Pre-fill percent complete. Suggest percent complete from cost-to-date or the schedule, and send it to the PM to confirm or adjust. This turns a blank-page task into a review.
8. Generate G702/G703 and run checks. Validate that no line exceeds 100 percent, that totals tie to the previous application, that retainage follows the contract, and that change orders billed are executed.
9. Route for approval. Send the PM or controller a short summary: totals, changes since last month, open exceptions. They approve, sign and submit.
10. Run in parallel, then cut over. For two or three cycles, build the draw both ways and compare. Fix every difference before you retire the manual process.

This is general information about construction billing practice, not legal advice. Lien waiver forms, retainage limits and prompt payment rules vary by state and by contract. Check your contract and your state's rules, and talk to your attorney about waiver language.

Your options: spreadsheets, software and AI agents

There are three realistic ways to get there, and many contractors end up combining them.

Better spreadsheets

A well-built G703 template with locked formulas, a change order log and a waiver tracker can remove most math errors. It does nothing for the chasing, matching and copying between systems, which is where most of the hours go.

Construction accounting and project management software

Many construction accounting and PM platforms can generate AIA-style pay apps from the data inside them, and some include lien waiver management. If your whole team already works in one platform, turn those features on first. The gaps usually show up at the edges: subs who email PDFs, lenders with their own portals and forms, and data split across two or three systems.

AI agents

An AI agent is software that can read documents, work across your existing systems and take steps on its own, while handing exceptions to a person. For draws, that means reading waivers and sub pay apps in whatever format they arrive, reconciling them to your accounting data, chasing what's missing and assembling the package. It is most useful when your process spans several tools that don't talk to each other. Our plain-English guide to AI agents explains how they differ from traditional automation.

Is it worth automating? Run the numbers

Draw automation pays off in two ways: hours saved on assembly and faster, cleaner payment. Estimate both before you spend anything.

Illustrative example: a contractor runs 8 active jobs. Each draw takes a PM about 5 hours to assemble and chase, so 40 hours a month. At a loaded cost of $60 per hour, that is $2,400 a month, or about $28,800 a year. If automation brings that to 1 hour of review per job, the labor saved is roughly $23,000 a year. Now add cash flow: if one in four draws is currently returned for a missing or incorrect waiver and each rejection delays payment by a week or two, cleaner first submissions shorten the time your money sits with the owner or lender.

Those numbers are made up for illustration. Plug in your own job count, hours and rejection rate. Our article on what AI implementation costs a small business walks through comparing that savings figure against the full cost of building and running an automation.
