What's Included

Built for how solar projects actually get paid.

Job costing is the baseline. Here’s what comes with it.

01

Monthly Bookkeeping

Full reconciliations across every account, every month, in QuickBooks Online — no backlog, no guesswork.

02

Project & Install Costing

Track equipment, permitting, labor, and install costs by project — so you know true margin per system, not just top-line revenue.

03

Progress Billing & Draws

Invoicing tied to install milestones, so cash comes in as the work gets done — not weeks behind it.

04

Rebate & Incentive Tracking

Keep tax credits, utility rebates, and financing draws straight, so nothing gets lost between approval and payout.

The Project Cash Cycle

Follow the money through every installation.

Solar projects rarely have perfectly matched cash inflows and outflows. Equipment, labor, subcontractors, permitting, and other costs may be paid well before the final customer payment is collected. Ample(x) Consultants helps connect those costs to the projects generating them.

The Financial Reality

Profitable project. Tight cash.

A solar project can be profitable on paper while still creating short-term cash pressure. Equipment may need to be purchased, crews paid, subcontractors funded, and permits covered before all customer payments are received.

Timing Matters.

Cash Out

  • Equipment
  • Materials
  • Payroll
  • Subcontractors
  • Permitting

Cash In

  • Deposits
  • Progress Payments
  • Final Payments
  • Applicable Incentive/Rebate Receipts

Solar projects may involve incentives, rebates, credits, or other program-related amounts that affect project accounting or cash timing. Ample(x) Consultants can help keep applicable amounts organized and properly reflected in the accounting records based on the scope of the engagement.

Project-Level Accounting

Revenue doesn't tell you whether an install made money.

Company-wide financial statements can show whether the business is profitable overall. Project-level accounting helps show which installations are actually producing the margins you expected.

Total Direct Project Cost$29,000
Estimated Gross Profit$13,000
Estimated Gross Margin31.0%

Did the project hit its expected margin?

Were equipment costs higher than estimated?

Did labor hours run over budget?

Did subcontractor costs change?

Where did we gain or lose margin?

The estimate is only the beginning.

Equipment & Materials$18,000$19,500
Labor$4,800$5,800
Subcontractors$2,000$2,400

Gross Margin38.1%31.0%

Tracking estimated costs against actual project costs helps identify where margins are changing — while there is still time to improve future pricing and operations.

Growth & Working Capital

More installs can create more financial pressure.

Growth in a solar business often requires spending money before collecting it. More projects can mean more equipment purchases, larger payroll, additional crews, subcontractor costs, vehicles, and working-capital needs.

How much cash do upcoming installs require?

When will customer payments arrive?

How many projects can we fund at once?

Accurate project accounting and cash-flow visibility can help leadership understand how growth affects the company's financial position.

Who It’s For

Solar installers who’ve outgrown spreadsheets.

Built for residential and commercial solar installers and EPCs doing $1M–$10M in revenue — where financing draws, rebate timing, and equipment costs make cash flow hard to track by hand.

Project Costs Are Spread Across Systems

Equipment, payroll, subcontractors, credit cards, and other project costs aren't consistently tied back to individual installations.

You Know Revenue — But Not Project Margin

Sales are growing, but it is difficult to determine which installs are producing the expected profit.

Cash Gets Tight Between Install and Payment

Costs are being paid before customer payments or other expected project receipts arrive.

Estimates and Actual Costs Don't Match

Projects look profitable when sold, but actual labor, equipment, or subcontractor costs are reducing margin.

The Spreadsheet Has Become the Accounting System

Critical project information lives outside the books, creating duplicated work and making reporting harder to trust.

Growth Is Getting Harder to Fund

The pipeline looks strong, but leadership needs better visibility into how much working capital upcoming projects will require.
