The Payment Terms That Make or Break Commercial Cash Flow
Why this matters
On a residential job you are paid for work: finish, invoice, get a check. On a commercial job you are paid for a correctly submitted, approved, and released billing, which is a very different thing. Between "the work is done" and "the money is in the account" sit a schedule, a format, an approval chain, and a hold-back, and each one adds weeks. Owners who do not see the full cycle price the job for a residential payment speed and then wonder why they are always short. This card maps where the weeks hide so you can price the wait and survive it.
The pay application, not the invoice
Commercial billing runs on a pay application (often called a pay app), a formal request for payment covering a set period, not a plain invoice.
- It is billed against a schedule of values (SOV), a line-item breakdown of your whole contract into pieces you can bill as you complete them. You submit the SOV early; every pay app after it says what percentage of each line is now done.
- It has a billing cutoff, usually monthly. Work you finish the day after the cutoff waits for next month's app, then the term after that. Miss a cutoff and you have added a full cycle.
- It must be in the required format, with the right backup (photos, quantities, lien waivers). A pay app in the wrong format does not get rejected loudly; it just sits.
The lesson: the clock does not start when the work is done. It starts when a clean, correctly formatted pay app lands before the cutoff.
The approval lag you do not control
Once your pay app is in, it travels a chain before a check is cut.
- The general contractor or construction manager reviews it, sometimes disputes a percentage, sometimes bundles it with every other sub's app.
- The owner and the owner's lender or architect approve the combined draw.
- Accounts payable runs it on their cycle.
Each hop is days to weeks. Net terms (payment a set number of days after approval) start at the end of this chain, not the beginning. A "net 30" job can be two months from finished work to cash once the approval lag is counted.
The clauses that lengthen the wait
Read the contract for the terms that decide your cash, because they vary widely.
- Pay-when-paid. The GC pays you a reasonable time after the owner pays them. Common and usually survivable, but it puts the owner's slowness on your back.
- Pay-if-paid. The GC pays you only if the owner ever pays them. This shifts the owner's insolvency risk onto you. Treat it as a red flag and price or resist it.
- Retainage. A percentage of every pay app held back until closeout. Your money, often your entire margin, arrives last and late. It gets its own article; just know it is subtracted from every draw.
- Conditional lien waiver required to release payment. You sign a waiver that becomes effective when the payment actually clears, exchanged each cycle. Fine when conditional; dangerous if they hand you an unconditional one to sign before the check clears.
The full timeline, drawn out
Picture one month's work on a commercial job:
- You perform the work through the billing cutoff.
- You submit a formatted pay app against the SOV, with backup and a lien waiver.
- The GC reviews, adjusts, and rolls it into the owner draw.
- The owner, lender, and architect approve.
- Net terms begin; AP pays on their cycle.
- Retainage on that draw stays behind until closeout.
The gap between step 1 and step 5 is your float, and it is measured in weeks to months, not days. Retainage stretches part of it out to the very end of the job.
How to price and survive the cycle
You cannot change how commercial pays, so you plan for it.
- Price the float in. Money you carry for months has a cost. Build it into the bid; do not discover it after.
- Bill on time, every cutoff. The single biggest self-inflicted delay is missing a cutoff. Have the pay app ready and clean before the date.
- Front-load the schedule of values where the contract allows. Weighting early line items (mobilization, early-completed work) speeds cash without over-billing, as long as it honestly tracks completed work.
- Keep a reserve sized to the float. A shop taking commercial needs cash to carry weeks of work before collection. Thin cash plus long terms is the classic way a busy shop cannot make payroll.
The mental model to keep
Residential cash is a check for finished work. Commercial cash is the output of a machine: schedule of values in, pay app before the cutoff, approval chain, terms, retainage held to the end. Learn every gear of that machine and you can price the wait and keep the reserve to outlast it. Ignore it and a profitable backlog will still starve you.
