# Marcus Dellacroix, Owner/GC at Dellacroix Contracting — read of Job Costing AI, May 19 2026

> 14 years in residential remodeling and light commercial, running 11 guys out of Chattanooga. QuickBooks Desktop, a shared Google Sheet my wife built in 2019, and a whiteboard in the shop that I photograph on Fridays.

## How I got here

Someone in the Contractor Talk Facebook group dropped a link with the comment "might be worth the $5 just to read it." I clicked it on my lunch break sitting in my truck outside a tile supplier. I had about 12 minutes before I needed to go back in and argue about a backordered order.

## What I clicked first

The interactive demo stopped me. Actual numbers: 186 of 200 labor hours, materials $1,320 over, tile scope creep. That is a job I have lived. The line "Projected margin 12.4% (down from 22% on the bid)" made my stomach drop a little because I have seen that exact slide in real life, except I saw it after the invoice cleared. The fact that someone put real numbers in instead of [INSERT CLIENT NAME] bubbles tells me at least one human being who has seen a construction job designed this page.

## Where I paused

The 30-day refund paragraph: "If your bids do not change and your margin reports do not tighten, we refund every dollar and walk away." I read that twice. That is either a real guarantee or it is counting on nobody actually asking for the refund. I genuinely cannot tell which yet. The money-back framing is confident and specific, which I respect, but it is also the exact kind of sentence a good copywriter writes to neutralize objection without the product actually being tested.

## What I distrusted

The honest disclosure section is doing two things at once and I am not sure they cancel each other out: "we don't have live customers on this idea yet." Okay, I appreciate that they said it. But then right above it they have a 73/100 score and a $140K Year-1 ARR estimate and "1 in 6 meaningful-success odds." Those numbers are from a Fermi model they built themselves. That is not third-party validation. That is a studio scoring its own homework and publishing the grade.

The "Built by Wishdeal Studio" footer also stops me. I do not know who Wishdeal is, I do not know if anyone there has ever run a crew or read a set of plans. The writing sounds like someone researched the pain point carefully, which is different from someone who has lived it.

Also: "AI codes them to the job and cost category." My receipts from the lumber yard have 40 line items. Is it coding OSB to framing and roofing felt to roofing, or is it dumping everything into Materials/Other and making me clean it up every Sunday night anyway?

## What would convince me

One real contractor, named, with a company I could Google, saying specifically: "I caught a $4,000 overrun on a bathroom before I invoiced." Not a screenshot of a margin meter. A person I can find on Facebook who runs crews and will tell me it works on a phone call.

On the QuickBooks sync specifically: I want to know if it breaks class tracking. Every app that says "two-way sync" has broken my class tracking at least once. I want a 2-minute Loom of someone syncing a real job, not a demo company, and the bookkeeper not having to touch anything.

## What I'd ask in an email reply

1. How does receipt coding handle a mixed-use ticket? Say I buy $600 in PVC and $180 in electrical conduit on the same Home Depot run, one receipt. Does the AI split that or does it ask me?

2. When your page says "two-way sync" with QuickBooks, does that mean time entries come from QB or does QB pull from you? Which system is the source of truth for payroll hours?

3. You say "no live customers yet." Are you building this after someone buys it, or is there a working version I can actually poke around in before I hand over $5?

## Verdict: on-the-fence

The pain is real, the demo numbers are specific, and the honest-disclosure section made me trust the page more than I expected to. But "no live customers" is a real answer that deserves a real follow-up, and I have been burned by QuickBooks integrations enough times that I need to see the sync actually work before I believe it.
