PAY APP TIMING

CONSTRUCTION PAY APP TIMING OPTIMIZATION WHAT BILLING LAG ACTUALLY COSTS.

QUICK ANSWER

Missing a billing cut-off by one week doesn't just delay that month's payment by a week. It defers that entire billing cycle permanently for the remainder of the project. On a 6 month project with $80,000 monthly billing, one late submission costs 30 days of float on the remaining $400,000 in project billings. SPM's first engagement action is a billing cut-off audit, which typically recovers $50K to $150K in the first cycle.

Most owners read a late pay app as a one week delay, because that's how it feels. It's not. The billing rolls into next month's cycle and every cycle behind it slides with it, so the cost is 30 days of float on all the money left in the contract rather than 30 days on one draw. That's why this is a billing discipline problem and not a slow paying GC problem. The GC is paying on the same terms he always did. The invoice reached him a month later than it could have.

THE DEFINITION

WHAT IT MEANS.

Billing lag is the number of days between a GC's monthly billing cut-off and the day you submit your pay application.

WHAT PAY APP TIMING COSTS

THE MATH ON MISSING A BILLING CYCLE, IT IS NOT JUST ONE MONTH.

01

The permanent deferral

When a pay app goes in one week late, it misses the GC's billing cut-off for that month, so the billing enters the following month's pay app. On a 30 day payment cycle, one late pay app defers $60K to $120K by 30 days permanently. Over a 6 month project with $80,000 monthly billing, one missed cut-off costs 30 days of float on $80,000 per cycle for the 5 remaining cycles, which is $400,000 in unnecessarily deferred cash.

02

The compound effect

A contractor with 6 active projects, each with a different billing cut-off, who consistently submits pay applications 5 to 10 days late is running $300,000 to $600,000 of unnecessarily deferred receivables at any given time. Every one of those GCs is paying on the terms he signed, and the only late document is yours. The correction is structural submission timing rather than an attempt to speed up somebody else's check run.

03

The cut-off discipline that isn't there

Discipline here means one billing cut-off date per month, with every active project submitting a pay app on or before that date. There are no exceptions for being busy, for waiting on a schedule of values revision, or for not having updated cost information. An imperfect pay app that's on time is worth more than a perfect pay app that misses the cut-off, and most subs have that ranking backwards.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The billing velocity calculation

A $5M revenue contractor who reduces average billing lag from 10 days to 2 days on a 30 day payment cycle reduces average AR outstanding by $109,000 permanently. That $109,000 was already earned, it was simply not being collected efficiently. No new contract and no rate increase is involved in producing it.

What the first audit returns

SPM's first engagement action on a new client is a billing cut-off audit across the active project list. It typically recovers $50K to $150K in the first cycle, because at least one project is billing a week or more behind a cut-off nobody had written down. The recovery comes from timing alone, with no change to scope, price, or terms.

HOW TO FIX IT

THREE STRUCTURAL CHANGES THAT ELIMINATE BILLING LAG.

Set one fixed cut-off date and enforce it

Pick a date, and the 25th is common. Every project bills on the 25th: the schedule of values is updated, the pay app is put together, and the submission happens that day. Month one is uncomfortable, and by month three it's automatic.

Build pay apps from weekly job cost data, not monthly

If job cost is being entered weekly, the cost to date is current on the 25th. If job cost is being entered monthly, the 25th means rebuilding four weeks of cost history from receipts and memory, which is the single most common reason pay apps go in late. Weekly bookkeeping is a prerequisite for billing cut-off discipline rather than a separate improvement project.

Track DSO by project and by GC

Days sales outstanding, measured from pay app submission to cash received and tracked by project and by GC, tells you which GC relationships have payment cycles that need an earlier submission. A GC on a 45 day cycle needs the pay app 15 days earlier than a GC on a 30 day cycle to put cash in the bank on the same date. That's a scheduling decision you can only make once the numbers are tracked by customer.

COMMON QUESTIONS

FREQUENTLY ASKED.

For each active project, find the GC's billing cut-off date and your last pay app submission date. The distance between the two is your billing lag on that project. If you don't know the GC's cut-off date for a project, that's the first thing to find out, and one call to the project manager settles it.
Build a two day buffer into your cut-off discipline. If you're targeting submission on the 25th and the GC's cut-off is the 28th, you have three days of buffer, so a move to the 26th still leaves you inside the window. The buffer is what makes the discipline survive a GC who reschedules, and it costs you nothing to carry.
Yes. Every active project's billing cut-off date is held in the CFOS engagement tracking. The weekly AR review includes confirmation that every project is on track to hit the current month's cut-off, and any pay app at risk of missing it's flagged in the Monday review with lead time to do something about it.
