Construction Accounting · Triangle Ledger Co.

Know which jobs make you money.
Before cash flow becomes a problem.

We help construction businesses understand job profitability, work in progress, retainage and cash flow through organized books and contractor-focused reporting. You see where projects are performing and where margins are slipping, before year-end tells you.

Less guessing. Better job visibility. More confident decisions.

Job costing

Every cost coded to the job it belongs to.

WIP schedules

Over- and under-billing, every month.

Retainage

Tracked by job until it's collected.

Cash timing

When money actually lands, not just what's owed.

What contractors ask us

Questions a regular P&L can't answer.

A standard profit and loss statement tells you whether the company made money. It doesn't tell you which jobs did, how much of your cash is really earned, or what's sitting in retainage. That's the gap we close.

Job profitability
"Which jobs actually made money?"

Labor, materials, equipment and subs coded to each job, so you can see gross margin by project instead of guessing from the bank balance.

Work in progress
"Are we overbilled or underbilled?"

A monthly WIP schedule compares what you've earned with what you've billed, so cash from billing ahead isn't mistaken for profit.

Retainage
"How much retainage is out there?"

Retainage receivable and payable tracked by job, so nothing gets forgotten at closeout.

Subcontractors
"Are subs hitting the right jobs?"

Subcontractor bills categorized to the right job and cost code, with 1099 and insurance tracking kept current.

Margin drift
"Is a job slipping while it's still running?"

Estimated versus actual margin, reviewed monthly, so you catch a problem job at 60% complete instead of at closeout.

Cash flow
"Can we make payroll during the slow draw?"

Receivables, payables and draw timing in one view, with forecasting on the larger packages.

Margin slipping
Job #2420 dropped from 18% to 12%.

Costs ran ahead of the estimate on a job that's 90% done. About $5,500 of expected profit is gone. Worth a look before the next bid like it.

Net overbilled $16,100
Some of your cash isn't earned yet.

Billing ahead on #2411 is good for cash, but the money still has work attached. It shouldn't be spent as profit.

$47,540 in retainage
Real money, collectible at closeout.

Tracked by job so it gets billed and collected on time instead of sitting on the balance sheet.

Sample schedule for a fictional contractor. Percent complete uses the cost-to-cost method. WIP schedules are prepared using appropriate accounting methods for your business and reviewed with your CPA when necessary.

What sets your price within the range.

Two contractors with the same revenue can need very different amounts of work. These four things decide it.

Active jobs

How many projects are open in a typical month.

Systems

QuickBooks alone, or paired with estimating and project tools.

Reporting

What your bank, bonding agent or partners need to see.

Advisory

How much review and decision support you want each month.

Onboarding starts with a diagnostic. We review your job setup, cost codes and open contracts before quoting. Historical cleanup or job-cost rebuilds are quoted separately as a fixed fee and never folded into your monthly price.

Built to work with your CPA

Your CPA gets clean jobs, not a shoebox.

Construction tax and financial statements depend on good job data. We keep the books in a shape your CPA can rely on, and we coordinate directly so you aren't the go-between.

  • WIP your CPA can review
    Schedules prepared consistently every month and reviewed with your CPA when the method or a job calls for it.
  • Year-end without the scramble
    Job-level detail, retainage balances and organized workpapers, handed off in the format your CPA asks for.
  • Ready for the bank and bonding agent
    Financials and WIP that hold up when a lender or surety asks for them.
