We priced a 213-line electrical BOM from a PDF in 8 minutes

A real bid-cycle quote came in as a marked-up PDF takeoff at 11:42 AM on a Tuesday. We sent priced lines back at 11:50 AM. Here is what happened, step by step, including the three lines the AI got wrong that we caught at review.

The setup

An NJ-based commercial electrical contractor sent a BOM for a tenant fit-out project. 213 lines spanning wire, conduit, devices, fixtures, and cable management. Format: a single PDF, generated from their estimator's takeoff software (McCormick, based on the page layout), with handwritten markups in three places where the engineer had updated the spec after the original takeoff was produced.

The bid was due at 5 PM the same day. Their normal workflow would have been to email the BOM to three distributors and wait for quotes back over the next 24-48 hours. They sent it to us at 11:42 AM as a test.

The timeline

11:42:08
BOM PDF received at quote@cintrasupply.com. 213 lines, 11 pages, 4.2 MB. Auto-acknowledged by the parser.
11:42:12
Parser begins. PDF text extracted directly (the file was generated by takeoff software, so the text layer was clean; no OCR needed).
11:43:31
First parse pass complete. 210 of 213 lines extracted with manufacturer + part number + quantity + UoM. 3 lines flagged: 2 with ambiguous part numbers (handwritten markup), 1 with a description but no part number ("LED downlight 4 in matching existing"). Flagged for human review.
11:43:35
Sourcing engine queries inventory and pricing across 4 supplier networks for the 210 parsed lines. Multi-supplier routing happens in parallel.
11:45:48
All 210 parsed lines come back with at least one priced offer. 8 lines have multiple offers across suppliers (commodity SKUs). 4 lines come back from only one supplier.
11:45:50
Human review phase begins. The 3 ambiguous lines plus 6 lines the system flagged for spec-substitution review go to the queue.
11:48:12
Operator (one of us) reviews the 9 flagged lines. Resolves 6 quickly. Asks the customer about the remaining 3 via a single reply email rather than holding the whole quote.
11:50:04
Priced quote sent. 210 lines fully priced. 3 lines marked "pending clarification" with our specific question on each. Quote held for the customer's bid validity through end of day.
8 min 56 sec BOM received to priced quote sent, 213 lines, single PDF input.

What the AI got wrong

This is the more useful part. Three lines came back priced where the AI had made an interpretation we caught at review. We did not publish the bad lines to the customer. But here is what they were:

Line 47: "2 boxes Carlon E977J-CTN"

The AI matched against the catalog and returned pricing for Carlon E977J as a 1-gang switch box. The actual part number "E977J-CTN" is a carton quantity SKU, which is 100 boxes per carton. So the customer was actually asking for 200 boxes, not 2. Caught at review because the unit price seemed too low for what the description implied. The line was re-priced with the correct quantity before send.

Line 112: "Hubbell receptacle, ivory, spec grade"

The AI returned a Hubbell HBL5262 (spec-grade duplex receptacle) in ivory. Fine match on first read. But the rest of the BOM was specifying "decora style" receptacles. A spec-grade decora receptacle from Hubbell is HBL2152IA, not HBL5262. The AI parsed the description literally without cross-checking against pattern usage in the rest of the BOM. We caught it because we manually skim every BOM to verify the style consistency. Re-priced before send.

Line 188: "Eaton BR240"

The AI returned pricing for Eaton BR240 as a 40A breaker. The BR240 part number is correct. But the panel schedule earlier in the BOM showed BR-series breakers in a CH-series panel. BR breakers do not fit CH panels. The customer either had a typo or had a non-standard adapter situation. We flagged the line and asked the customer rather than substituting silently.

The lessons

1. Speed is not the same as accuracy

If we had just sent the AI-generated quote straight to the customer at 11:48, we would have shipped three meaningful errors. The 2 minutes of human review at the end is non-optional. AI parses fast. Humans catch the things that require reading the BOM in context.

2. The "fast" claim is end-to-end, not just AI processing

The AI portion of this took about 3.5 minutes (parse + source). The human review took 2.5 minutes. The send took under a minute. The marketing claim "BOM priced in 8 minutes" includes the review. We do not advertise the AI-only time because customers do not want AI-only quotes. They want correct quotes.

3. Handwritten markup is the killer feature

The single biggest reason this customer sent the BOM to us instead of the distributor portal: the engineer's handwritten markups on the PDF. Distributor portals require you to retype every line. Our parser handled the takeoff text and flagged the markups for human resolution. That alone was worth the test for this contractor.

4. Multi-supplier routing is invisible to the customer

The customer got back one quote, on one piece of paper, with one set of payment terms. Under the hood, the 210 priced lines came from 4 different supplier networks. The customer does not know or care. That is the right answer.

What happened next

The customer won the bid. They placed the order with us at the quoted prices on the following Tuesday after the GC awarded. Delivery to job site went smoothly. They sent us their next BOM, a smaller one, the following week. We are now in their normal vendor rotation alongside their two existing distributors.

That last part is the actual outcome we care about. Speed of a one-shot quote is a demo. Recurring vendor rotation is a customer.

If you want to test this

Send a real BOM. PDF, Excel, photo, scan, whatever you have. We will price it. There is no commitment, no login, no sales follow-up. The point is for you to see the same timeline this customer saw and decide for yourself whether it is useful.
