CONSTRUCTION ACCOUNTS RECEIVABLE, MANAGED.

QUICK ANSWER

Healthy AR aging for a subcontractor is around 45 days, with 90+ days signaling weak collection discipline and 30 days representing a strong position. SPM records and tracks AR aging with a defined follow-up cadence at 30, 60, and 90 days, and flags collection issues early, but doesn't execute collections or payments on the client's behalf.

AR aging left alone gets longer. An invoice that should collect in 30 days stretches to 45, then 60, because nobody owns the follow up on a set schedule. That stretch is rarely a payer problem, it's a process problem, and it compounds across every open invoice at once. SPM tracks AR aging against a defined benchmark and cadence, and records AR activity accurately in the books. Collection execution itself, the calls and the follow up with the GC, stays with you, because the person who holds the relationship gets paid faster than a third party ever will.

THE DEFINITION

WHAT IT MEANS.

Accounts receivable management for a subcontractor is the work of recording AR accurately, tracking aging against a benchmark, and flagging follow up at defined thresholds before invoices drift.

Days Sales Outstanding, DSO, is the standard measure of AR health. It rolls the whole aging report into one number: on average, how many days it takes to collect an invoice after you bill it. The aging report gives you the detail behind that number, and the two get read together every month rather than one instead of the other.

COMMON BELIEFS

WHAT IS TRUE INSTEAD.

01

"Our clients are just slow payers"

Some of them are, but most AR slowdown is a collection cadence problem rather than a payer problem. A defined follow up schedule at 30, 60, and 90 days catches the slowdown before it becomes the way your business operates. The GC who pays in 60 days when nobody calls will often pay in 40 when somebody does, and that difference is process, not relationship.

02

"We'll get to collections when we have time"

Without a defined cadence and clear trigger points, collection follow up competes with every other priority in the business and it loses every time. That's how invoices drift past 90 days. Follow up has to be scheduled work owned by a person, not something that happens when the week is calm, because the week is never calm.

03

"You keep our books, so you must chase collections too"

SPM records and tracks AR aging accurately and flags the follow up triggers, but collection execution, the outreach to the GC, stays with the client. That scope boundary is deliberate and it's the same on every SPM engagement. We will tell you who to call and when, and we won't make the call for you.

COMMON QUESTIONS

FREQUENTLY ASKED.

45 days is the target for a well managed subcontractor, with 30 days a strong position and 90 days or more signaling weak collection discipline that needs attention. The right number inside that range depends on your contract terms and how many GCs you work with, but 45 is the line to measure against.

No. SPM records AR activity, tracks aging against the benchmark, and flags follow up triggers at 30, 60, and 90 days, but doesn't execute collections or make collection calls on the client's behalf.

AR aging goes straight into the cash flow forecast. Invoices that go past their expected collection date stretch every assumption the forecast is built on, which is why current, accurate aging data is what makes a forecast worth using.

Aging tracks how long invoices have been outstanding and flags them at defined thresholds. Collection is the active follow up, the calls, the letters, and the negotiation that recovers the cash, and that side stays with the client.

Yes. SPM defines the follow up cadence and the trigger points as part of the Cash Control System, so your team knows when and how to follow up even though the outreach itself isn't performed by SPM.
