About AR Mastery

Built by someone who understands construction — and the cash flow problems that come with it.

Construction companies do some of the most demanding work in the economy. Getting paid for it shouldn't be the hardest part.

"I didn't grow up with connections or capital. I grew up watching people work hard and still struggle to get paid for it."

I'm Reena — someone who built everything from the ground up. I didn't come from money or connections. I came from a place where every dollar had weight, where financial uncertainty wasn't abstract — it was the kitchen table, the sleepless nights, the quiet calculation of what could wait and what couldn't. That foundation never left me. It's in everything I do.

Over 15 years, I've worked deep inside accounts receivable — not from the outside looking in, but embedded in the daily reality of it. The billing cycles. The aging reports that never seemed to move. The difficult conversations. The quiet, grinding stress of watching cash flow dry up while the work was already done and the invoices were already sent. I've sat with that pressure alongside construction businesses of every size — from sole-trade subcontractors to multi-project general contractors and developers — and helped them recover millions of dollars in receivables that had been written off, delayed, or simply overlooked. That work is personal to me. It always has been.

15+ Years. Millions Recovered. Construction.

From sole-trade contractors to multi-project GCs — the AR problem is the same. So is the solution.

Most unpaid construction invoices aren't about bad clients.

Here's what most contractors get wrong: they assume that if a GC or owner isn't paying, the relationship is broken. In my experience, that's rarely true. Most invoices stall because of process gaps — progress billing that doesn't match the contract, holdback disputes that were never properly documented, or simply a lack of consistent, professional follow-up.

The goal has never been to pressure clients or escalate to collections. The goal is to understand exactly where the breakdown is happening — and fix it in a way that keeps the working relationship intact. In construction, you need the next contract as much as you need payment on this one. Cash flow and client relationships don't have to be in conflict.

Why I built this as a remote, flat-fee service.

Most construction businesses — regardless of how many projects they're running or how much revenue they generate — are still managing AR on instinct and goodwill. They're issuing invoices, following up manually, and hoping the money arrives. Meanwhile, the same receivables sit on the same aging report, week after week, quietly compounding into a cash flow problem.

I built AR Mastery to bring a structured, expert eye to that problem — without the overhead of a long retainer, an in-person engagement, or a consulting firm's billing rate. By keeping the service remote, written, and delivered at a flat fee, I can focus entirely on what matters: giving you a clear, actionable picture of your receivables in the time it takes most firms to write a proposal.

For construction businesses sitting on significant outstanding invoices, the assessment often surfaces issues that have gone unaddressed for months. What you do with those findings is entirely up to you — and it doesn't require you to commit to anything beyond the report itself.

Real Results

What the assessment looks like in practice.

Every engagement is confidential. The examples below are anonymised, but the numbers and outcomes are real.

$67K

Recovered

Roofing Subcontractor

$67,000 in holdbacks flagged for follow-up — all three released after client implemented the plan.

A roofing subcontractor came to AR Mastery with three projects where holdbacks had been sitting unreleased for over a year. The GC had raised deficiency concerns, but no formal deficiency list had ever been issued — and the subcontractor had no documented record of substantial completion. The AR Assessment identified the exact documentation gaps, outlined the contractual basis for release, and provided a step-by-step plan. The client implemented the recommendations independently. All three holdbacks were subsequently released in full.

What guides every engagement

Honesty over optimism

I'll tell you what your AR data actually shows — not what you want to hear. The report is direct, specific, and actionable, whether you're a two-person trades company or a multi-project GC.

Relationships first

Recovery strategies are designed to preserve your client relationships, not damage them. In construction, your next contract depends on the same people you're trying to collect from.

Accessible expertise

You shouldn't need a large budget or a full AR department to get professional guidance. This service is priced so that any construction business with stuck receivables can afford it.

Built for construction companies with $20K or more in outstanding invoices.

The AR Assessment will show you exactly what's stuck, why it's stuck, and what to do about it — in a written report delivered within 7 business days. No calls, no commitments beyond the report.
