Stop losing money between the quote and the invoice

Real builder example

One plumbing quote. One missed total. 30 seconds to catch it.

A Raleigh residential builder sent Kiron a plumber quote that looked ready to approve. The total was about $12K, but the line items only added up to about $9K. Ella flagged the gap immediately, and the builder went back to the plumber for a corrected quote.

Quoted total

$12,072

Line items

$9,692

Gap flagged

$2,380

Without Kiron, the $12K quote was on track for approval. The issue was not hidden; no one had time to manually re-add the quote before signing off.

Tight margins don’t leave room for billing mistakes

On a custom home with 15–20 subcontractors, invoices stack up fast. Your PM is juggling schedules, inspections, and homeowner requests — they don't have time to cross-check every line item against every quote version. That's where money leaks.

Cumulative overbilling

Your tile sub has three invoices totaling $15,200 against an $11,500 order and a $1,200 change order. That's $2,500 over commitment — but no one caught it because each invoice looked reasonable on its own.

Change orders without paperwork

The homeowner asks for upgraded fixtures in the master bath. Your PM says yes on-site. Three weeks later there's an invoice with no signed change order and no approved quote. Ella flags the missing CO automatically.

Allowance overruns you catch too late

Lighting, flooring, countertops — allowances look fine until the final invoices arrive 20% over. Ella tracks allowance spend per line item in real time, so you know before it's too late.

How it works

How Ella protects your margin

No new software to learn. Ella plugs into your inbox, builds a complete cost picture per vendor, and reviews every new document that comes in.

Connect your inbox

Link your Gmail or Outlook. Ella reads every quote, invoice, change order, and photo your subs send — classifies each document, extracts line items, and resolves vendors automatically.

Ella builds the cost picture

Ella tracks the full document chain: quote → order → invoice → change order. She knows which quote version was approved, what's been invoiced to date, and where the commitment stands for every vendor.

Ella Insights flag risks

Every new cost document triggers financial checks — commitment variance, duplicate detection, missing change orders, allowance risk, and budget overruns. Issues are flagged with evidence before anything gets approved.

Approve or push back in minutes

You get a decision packet with line-item comparisons, contract references, and a clear recommendation. Ella even auto-rejects superseded quotes when a vendor sends a revision.

Real example

ABC Tile invoices exceed commitment by $2,500

ABC Tile has a confirmed order for $11,500 plus one approved change order for $1,200 — total commitment of $12,700. After three invoices, they've billed $15,200. Ella computes the exact variance, identifies the overage, and recommends holding approval until the gap is resolved.

Each invoice looked reasonable on its own. Only the cumulative view catches the $2,500 overrun.

Automatic action

Vendor sends a revised quote — Ella handles it

When a sub sends a new quote with the same doc number, Ella recognizes it as a revision — not a duplicate. She auto-rejects the old quote, calculates the price delta, and flags the new one for your review. No manual cleanup.

Your cost ledger stays clean. Your commitment baseline stays accurate. You just approve or push back.

Built for every type of residential project

Custom homes

15–20 subs, homeowner change orders, finish selections — Ella tracks every vendor's commitment and flags the moment cumulative invoices exceed what was quoted.

Spec homes

Running multiple lots with the same subs? Ella catches when the same trade bills differently across identical scopes — or when a vendor reuses a quote number with a higher price.

Renovations & additions

Scope changes constantly on reno jobs. When a vendor sends a revised quote, Ella auto-rejects the old one, calculates the price delta, and flags the revision for your review.

Multi-lot developments

Manage a portfolio of active builds without adding headcount. Ella scales verification across every project — tracking trade-level spend and vendor performance across your book.
