PAY APPLICATION BILLING

HOW MUCH TO BILL ON PAY APP 1.

QUICK ANSWER

You spend on mobilization, submittals, permits, bond, and first material weeks before Pay App 1 clears the bank, and that clearing runs 30 to 60 days from the day you submit. When the float isn't priced into App 1, you're financing the GC's job on your own credit line. The minimum is the cost deployed plus the cost of carrying it: $75K deployed plus ($75K times 9% divided by 365, times 60 days) is $76,110, which against a $625,000 contract is a 12.2% front-load.

The dollar amount on any one job looks small, and the habit is what counts. Two months of startup cost carried on the line of credit reads as a rounding error until four jobs are doing it at once and the operating account never recovers between draws. A schedule of values that carries mobilization, first material procurement, and permits and bond as separate itemized lines collects that money in the first cycle instead of the third. General contractors approve line items they can read. They push back on one large front-loaded number with no detail under it.

THE CALCULATOR

TWO QUESTIONS, TWO TABS.

What you have to bill on the first application to stop financing the front end of the job yourself. Mobilization, submittals, bonds and first material are all paid for before any money comes in.

The same submission emails you the Schedule of Values and Pay Application Template, which is the workbook that does this for 36applications with 7 tie-out checks, so a rejected application stops costing you a month.

THE DEFINITION

WHAT IT MEANS.

The Pay App 1 minimum is the cost you deploy on a job before that first application clears the bank, plus the financing cost of carrying that money until it does.

Two terms get mixed up in this conversation. Overbilling is billing more than your percent complete supports, and it posts as a liability on the balance sheet, billings in excess of earned revenue. Underbilling is the reverse, revenue you've earned and haven't billed yet, and it posts as an asset, costs in excess of billings. Underbilling is the one that hurts, because the revenue is recognized, the profit is reported, and the cash isn't in the bank. Every day of underbilling is a day the line of credit is drawn.

Front-loading App 1 puts you in an overbilled position on purpose, and that's fine as long as you know it and the rest of the schedule of values earns it back as the job runs. What isn't fine is an overbilled position nobody tracked, because it reverses in the last two months of the job when the billing runs out and the cost doesn't.

WHAT WE SEE IN THIS BUSINESS

WHY MONTH ONE DRAINS THE ACCOUNT.

01

The spending starts 30 to 60 days before the money comes in

Mobilization, submittals, permits, bond, and first material all get paid before Pay App 1 clears the bank, and that clearing runs 30 to 60 days from submission. Every dollar spent inside that window comes out of working capital rather than out of the project. The job has done nothing wrong yet and the account is already down.

02

The schedule of values is flat

A schedule of values built as an even spread across the contract bills the same percentage in Month 1 that it bills in Month 6. Month 1 doesn't cost what Month 6 costs. The startup spending is front-end weighted and the billing isn't, so the difference between them gets funded by your line of credit at your rate instead of the GC's.

03

Going upside down on one job pulls cash off another

You're upside down when your costs to date on a job exceed the cash you've collected on that same job. On one job that's a tight month. Across four, keeping the upside down job alive means pulling cash off the jobs that are collecting, and that's the fast track to cash flow chaos.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The App 1 minimum

MINIMUM BILLING = COSTS DEPLOYED + (COSTS x LOC RATE / 365 x DAYS TO PAYMENT). Run it on a job with $75K deployed, a 9% line of credit rate, and 60 days to payment, and the minimum is $76,110. Against a $625,000 contract, that's a 12.2% minimum front-load on the schedule of values.

Percent complete and earned revenue

% COMPLETE = COST TO DATE / ESTIMATED TOTAL COST, and RECOGNIZED REVENUE = CONTRACT VALUE x % COMPLETE. With $125K of cost against a $500K estimate you're 25% complete, so recognized revenue on a $625K contract is $156,250. Bill under that figure and you're underbilled. Bill over it and you're overbilled.

The mobilization line item

A mobilization line item of 3 to 7 percent of contract value is standard and defensible, and it only bills when it's itemized on the schedule of values. When the minimum works out to 12%, spread it across mobilization at 5 to 7 percent, first material procurement, and permits and bond as separate lines rather than asking for 12% in one.

HOW SPM FIXES IT

HOW THE FIRST BILLING GETS SET.

The App 1 minimum gets calculated before the SOV goes in

The minimum is run off your job budget, your line of credit rate, and how that GC paid on the last project, then the schedule of values gets built to hit it. The number goes in before the SOV is submitted, because once the GC approves the SOV you're negotiating against your own document.

Front-loading gets broken into line items a GC will approve

One large number at the top of the SOV invites a fight. Mobilization, first material procurement, permits, and bond as four separate itemized lines invites a review instead. Same total, different conversation, and every line is defensible with a cost behind it.

The overbilling and underbilling position gets read every month

Billed to date against earned revenue tells you whether each open job is overbilled or underbilled. That's calculated monthly out of the job cost ledger for every client, alongside the cost to complete review and the 13 week cash flow forecast, so an underbilled job gets caught in the month it happens rather than at close-out.

COMMON QUESTIONS

FREQUENTLY ASKED.

The distance between when mobilization spending starts and when Pay App 1 clears the bank. That stretch is typically 30 to 60 days. Every dollar spent during that window comes from working capital, not from the project, and the job can't pay any of it back until the first application collects.
You're upside down when your costs to date exceed the cash you've collected on that same job. On one project it's a tight month you can absorb. Across several, going upside down on one means pulling cash off another to keep it alive, which is the fast track to cash flow chaos.
Enough to cover mobilization plus the financing cost of the float period, without triggering GC pushback. The minimum calculation gives you the floor. If it comes out at 12%, spread that across mobilization at 5 to 7 percent, first material procurement, and permits and bond as separate SOV line items instead of asking for 12% on one line.
Usually yes, but only when it's itemized in the schedule of values. A mobilization line item of 3 to 7 percent of contract value is standard and defensible. If it's not on the SOV there's nothing to bill against, and adding it after the GC has approved the SOV is a much harder ask than putting it there at the start.
Overbilling is billing more than your percentage of completion supports. It posts as a liability on the balance sheet, billings in excess of earned revenue. A front-loaded App 1 puts you overbilled on purpose and that's fine. Bonding companies and lenders flag heavy overbilling across a whole work in progress schedule as a risk indicator, so the position has to be tracked and earned back as the job runs.
