The 2026 Broker Stack · Section 4

The AI Stack.

Three workflows. Same deal. Watch the delta.

The workflow visualizer

Four stages. Twelve tasks. AI runs eight of them.

A deal moves through four stages from the moment it hits your inbox to the moment it funds. Intake → Underwriting → Submission → Follow-up. An old-school broker does every step by hand. An AI-native broker runs a stack that handles the eight repeatable, rule-based pieces automatically and gets out of the way for the four decisions that actually need human judgment.

Old-school ~45 min/deal
Open file Scroll 40 pages Tally deposits Eyeball NSFs Spot MCA debits Tier call (maybe)
AI-native ~30 sec/deal
Statement uploads Local LLM extracts 5 numbers Reasoning pass cross-checks buy box Tier 1 / Tier 2 / Pass

The visual loops through one deal. AI-handled steps glow as they execute. Human-handled steps stay neutral. Watch the counters: 45 min → 4 min. Manual → Auto. 8 lenders → 1 click. That's the delta. The rest of this section breaks it down into three workflows, the tools that run them, and one working prompt you can run yourself in 60 seconds.

Workflow 1 of 3

AI Underwriting.

Input

A merchant submits a deal. Four months of bank statements arrive as a single document. The broker has 60 seconds to form a view on whether this is fundable, what tier it is, and which categories to target.

What old-school brokers do

Open the statement file. Scroll through 40 pages of transactions. Tally deposits with a calculator or a scratch pad. Try to eyeball NSF fees. Miss half of them because they're labeled inconsistently. Try to spot MCA debits in the transaction list. Miss the pattern because the originator names are disguised. Open a spreadsheet. Input the numbers. Compare against a mental buy box that hasn't been updated in six months. Form a tentative tier recommendation.

Time per deal: 30–45 min Error rate: high Consistency across deals: zero
What the AI workflow does

A local LLM is an AI model that runs on the broker's own hardware. Sensitive data never leaves the workstation.

Statements upload to a parsing pipeline. A local LLM running on the broker's own workstation reads every transaction line and outputs the five numbers underwriting actually runs on:

  • Monthly revenue (gross deposits, adjusted for intra-account transfers)
  • Average daily balance
  • NSF count and pattern
  • Existing MCA debits, identified by payment cadence and processor signatures
  • Deposit consistency (variance across months)

The same pass flags anomalies. Sudden revenue drops, merchant-category mismatches against the application, stacked MCA patterns, round-number deposits that look artificial. Then a reasoning pass (a frontier reasoning LLM via API when no PII is involved, or the same local model when PII can't leave the machine) cross-references those numbers against composite buy box thresholds from Section 1 and produces a tier call: Tier 1 / Tier 2 / hard pass.

Time per deal: under 30 sec Error rate: low & consistent Underwritten the same way: Tuesday and Friday
Why local LLM for the statement read

Bank statements are PII. California's CCPA updates governing Automated Decisionmaking Technology (ADMT) took effect January 1, 2026, with full ADMT compliance obligations for businesses making financial decisions required by January 1, 2027, and more states are moving the same direction. Sending identifiable financial documents to a third-party API is a liability. A local model does the extraction with zero data leaving your hardware.[1][2][9]

Why the reasoning pass uses a frontier model

A frontier reasoning model brings a 1M-token context window, an output budget large enough to draft the full submission in one pass, and financial-reasoning capability that holds up when you're asking it to weigh seven signals against a buy box and defend the call. Cheaper models exist. The math of one mis-tiered deal a week says don't use them at this layer.

The workflow structure

parse → extract → flag → tier. Four stages, each with a deterministic contract between the parser, the local LLM, and the reasoning pass.

A redacted sample of the AI's underwriting output

Deal ID: R-0418
Monthly revenue (avg 4 mo): $47,300
Avg daily balance: $3,120
NSFs (90-day): 2
MCA debits detected: 0 (clean)
Deposit variance: 11% (stable)

Flags: MCC mismatch: application says "restaurant," processor codes as 5812 AND 5999. Verify.
Tier call: Tier 1. MCA primary. Equipment backup with invoice.

Tool categories

Local LLM on consumer GPU hardware, open-source document parsing library, a reasoning LLM via API for the tier call, a workflow orchestrator to chain them. Each part is described in § The Actual Stack below.

What this report does NOT show
  • The production prompts that make underwriting output reliable across edge cases. This is where 60% of the real work sits.
  • Model selection and system-instruction tuning for each step
  • Integration logic between parser, LLM, and orchestrator
  • Error handling for malformed statements, image-only scans, mid-statement account changes
  • The composite buy box thresholds hard-coded into the tier call (those are the Lender Matrix data from the Accelerator)

This is Accelerator Week 5 territory. The signal isn't that it's gated. The signal is that it's deep enough to need its own week.

Workflow 2 of 3

AI-Drafted Submission.

Input

Qualified deal, all stips collected: bank statements, driver's license, voided check, application. Broker has 3–5 funder matches from Workflow 1. Time to submit.

What old-school brokers do

Open a new email. Try to remember Funder A's preferred intake format. Do they want a formatted summary, a loose paragraph, or just the stips attached? Try to remember the right AE. Draft the email. Attach four files. Send. Open another email for Funder B. Their intake format is different. They want a one-paragraph executive summary up top, then stips below. Reformat. Re-attach. Send. Repeat for C, D, E.

Time per submission round: 45–60 min Format errors: common Consequence: flagged by AE, pull-through drops
What the AI workflow does

The qualified deal drops into the submission orchestrator. The broker confirms the funder matches already produced by Workflow 1 and clicks submit. The orchestrator fans out to the AI drafter, which produces 3–5 submission emails in parallel. Each in the format that funder actually prefers, each with the right summary length, the right tone, the right attachments referenced in the right order. The broker reviews all drafts in a single pane, makes light edits where needed, hits send.

A 45-minute workflow collapses to 4 minutes. Every submission goes out in the format the funder prefers. Format hygiene goes up, AE relationships strengthen instead of eroding, and better relationships mean faster answers and better offers for the merchant. Which is the whole loop.

The concept

Format-specific submission templates: each funder has an intake format their AEs scan fastest. Match it on every send.

A redacted example · three drafts for the same deal, side by side

Draft 1 · Format "Short Summary + Stips"

"New submission. $47K/mo avg, 18 mo TIB, 640 FICO, restaurant. 2 NSFs 90-day. Clean stack. Seeking $40K working capital. Stips attached. [stip list]"

Draft 2 · Format "Structured Fields"

MERCHANT: [redacted] | TIB: 18 mo | REV: $47K/mo | FICO: 640 | ASK: $40K | POSITION: 1st | STIPS: complete (list below)

Draft 3 · Format "Narrative + Context"

"Hey [AE], sending over a clean 1st-position look. Restaurant, 18 months in, running $47K/mo average with stable deposits and only 2 NSFs in the last 90. Owner wants $40K for kitchen buildout. No current advances. Stips attached. Let me know if you need anything else."

The downstream implication

Format-correct submissions = stronger AE relationships = faster approvals and better offers. Compounding advantage per deal.

What this report does NOT show
  • Which funders prefer which format (same confidentiality rule as Section 1: submission-format intelligence is one of the highest-value assets in the Accelerator's Lender Matrix, and publishing it broadly would get ISOs blacklisted within a cycle)
  • The production prompts that produce consistent drafts across both models
  • Orchestration logic that fans a single deal across N parallel drafts and routes the approvals
  • Attachment handling, naming conventions, automated stip packaging
Workflow 3 of 3

Automated Follow-up.

Input

Submitted deal is in a funder's queue. Could be an hour. Could be three days. Broker doesn't know. Meanwhile, the merchant is getting called by five other brokers who pulled the same UCC trigger data.

What old-school brokers do

Make a phone reminder. Forget. Remember three days later. Send a "just checking in!" email that reads like desperation. AE is annoyed. Merchant accepted someone else's offer two days ago because that broker followed up on day one and closed the loop. Deal is dead and the broker doesn't know until they finally get a reply that says "merchant funded elsewhere."

What the AI workflow does

The orchestrator tracks the state of every submitted deal: submitted → under review → counteroffer → approved → declined → funded. Each state has a follow-up cadence calibrated to that funder's preference. The system drafts the follow-up at the right time, in the right tone, referencing the specific deal. No generic template energy. Broker reviews, approves, sends in one click.

When a counteroffer arrives, the reasoning model drafts a merchant-facing response that explains the counter in plain language, shows the implied cost, and asks for a decision. When a decline arrives, the orchestrator re-routes the deal to the next-best funder match from the original Workflow 1 ranking, pre-drafts the new submission in the next funder's preferred format, queues it for broker approval.

No deal: forgotten No counter: sits 48 hours No decline: dies · re-routed in < 15 min

The concept

Submission-state tracking across the deal lifecycle, with cadences calibrated to each funder.

Dashboard view

Three active deals, each showing current state, last funder action, next broker action, and time-to-next-action. Broker glances at the board, clicks the three actions, moves on with their day.

What this report does NOT show
  • The funder-specific cadences (each funder expects a different rhythm, getting it right separates top ISOs from mediocre ones)
  • The re-routing logic that maps declined deals back to the buy box matrix and selects the next best funder automatically
  • Email / CRM / underwriting integration patterns
  • State-machine logic and failure recovery
The actual stack · April 2026

The components are public. The decisions aren't.

Six components below. Each chosen for a reason most brokers haven't thought through. The reasoning behind each choice, and the integration between them, is what separates a broker running this stack from one still copy-pasting prompts into a chat window. That's the Accelerator.

Reasoning layer

A frontier reasoning model.

Primary reasoning layer for underwriting judgment, submission drafting, and counteroffer logic. A 1M-token context window holds a full deal file (statements, application, prior correspondence, funder requirements) in a single pass, so the model reasons across all of it at once. This is the layer where underwriting judgment actually lives.

Why: Reasoning quality is the line between a stack that mis-tiers a deal once a week and one that doesn't. A single mis-tier costs more in lost commission than the model bill costs in a year.

Local LLM stack (PII-safe)

A local LLM stack.

A local LLM is an AI model that runs on the broker's own hardware. Sensitive data never leaves the workstation.

For anything touching merchant PII. Capable local models now run well on a single consumer GPU in the 24 to 32GB VRAM range, the kind of card a working broker buys once and owns forever. Prior-generation cards remain the cheapest serious entry point. Hardware cost is one-time. After that, every statement you process costs $0 and leaves zero merchant data on anyone else's servers.

Why: Bank statements contain PII and shouldn't leave your hardware. Period. California's ADMT financial-decision compliance kicks in January 2027 and other states are following. This is a compliance position, not just a preference.

Workflow orchestration

A self-hosted workflow orchestrator.

A workflow orchestrator is software that connects the AI tools, CRM, email, and document parser into one pipeline so they run as one system instead of separate apps.

The glue. Connects the reasoning model, the local LLM, your CRM, the document parser, and the email pipeline into a single deal flow that runs without a human touching it between intake and submission-ready file. Free, self-hosted, unlimited executions, deployable on a $5/month VPS or your own workstation.

Why: Self-hosted means zero per-execution cost, full control over your data, no vendor lock-in. Hosted orchestrators charge per run and store every deal's intermediate state on their servers. Your ceiling is your time, not your tooling cost.

CRM

A CRM built for how alternative business funding brokers actually work.

Generic sales CRMs were built for SaaS reps closing annual contracts, not brokers running 20 to 40 active deals across a 200+ lender buy box. They have no native fields for funder positions, daily debit count, stip status, or AE relationship history. Brokers end up storing those in spreadsheets, in Slack, or in memory. Every workaround is a place deals leak.

Why: The orchestrator is the brain. The CRM is the memory. Broker-specific fields belong in a broker-specific CRM, not glued onto a generic pipeline tool built for a different industry. (We're building one. More soon.)

Email integration

Direct email pipeline.

Standard open protocols. Plumbing, not strategy.

Why: No third-party wrapper between you and the wire. Closer to the wire means fewer surprises when a deal is on the clock.

Document parsing library

An open-source document parser.

A document parser extracts structured data, like dollar amounts and dates, from messy uploaded files.

Open-source library. Pulls structured data (dollar amounts, dates, transaction lines, account balances) from both text-based PDFs and image-only scans before the reasoning model ever sees the document.

Why: The parser sits upstream of every other decision. A garbled extraction poisons your read of the deal. Owning this layer means owning the data quality the rest of your stack runs on.

What the stack is NOT
  • It is not a "do-it-all" SaaS platform. Every broker-specific all-in-one pitched in the last two years either stores merchant data on someone else's servers (PII liability), charges per-execution (math breaks at scale), or locks you in so hard you can't leave without rebuilding from scratch. Pass on all three.
  • It is not a no-code drag-and-drop builder that abstracts away the orchestration layer. If you don't understand what your workflow is doing, you can't debug it when it breaks, and you'll be permanently dependent on a vendor who doesn't know your business.

Own the stack. Don't rent it.

Copy this prompt, run it yourself

Everything above is abstract until you feel it work.

Below is one working prompt that does one narrow task. It pulls two numbers off a bank statement: gross deposits for the period, and the ending balance. Copy it, paste it into a frontier reasoning model with file-upload support. claude.ai works. Upload a sample bank statement (yours, a merchant's with permission, or a dummy), run it. You'll feel the parse-then-extract pattern Workflow 1 runs in production.

This is narrow on purpose. Not the production prompt. The production prompt extracts five numbers, flags anomalies, and defends the tier call. This one extracts two. It is a 60-second proof of concept.

prompt · bank-statement-extract.md 
You are a commercial alternative-funding underwriter reviewing a merchant's bank statement.

From the attached statement, extract exactly two numbers and return them in the structured format below. Show your arithmetic in one line under each value. If a value cannot be determined from the statement, return "unknown". Do not estimate.

1. GROSS DEPOSITS for the statement period (sum of all credit transactions, excluding transfers between the account holder's own accounts if identifiable).
2. ENDING BALANCE on the last day of the statement period.

Output format:

GROSS DEPOSITS: $___
 (arithmetic: ___)
ENDING BALANCE: $___

Do not interpret, score, or recommend. Return only the two values and your work.
Copied to clipboard

Run it. See the output. Then picture that output wired into a buy box, a submission drafter, and a follow-up scheduler. That's the rest of the stack.

The before / after time calculator

Plug in your volume. See the math.

Three inputs: deals/month, current avg per-deal workflow time, and average commission per funded deal. The calculator returns the weekly hours back, the additional capacity at your old-school speed, and the additional commission that was invisible in your P&L.

Your numbers

Tell the calculator about your current desk.

$
The default values populate a typical 20-deals/month desk.
Press Run the math to see the weekly hours back and the additional commission unlocked.

Defaults shown reflect a broker running 20 deals/month at 90 minutes each (manual). Adjust to your own pipeline. The Accelerator's founding-cohort tuition is a rounding error against the recovered capacity for any working broker. That's arithmetic, not a pitch.

Why the stack is not optional

The brokers who built AI-native workflows in 2024–2025 are currently running several times the deal volume of brokers who didn't, with smaller teams and better funder relationships. The brokers who haven't built it yet are not falling behind slowly. They're being out-cycled on every deal, every day, by operators who got the next-best-funder response out in 15 minutes while the old-school broker was still opening the first statement.

It's already happening across the wholesale channel. Funders track submission quality; the cleanest ISOs get the first look and the best offers. AI-native brokers produce cleaner submissions, faster, in the format each funder wants. That's compounding advantage: per deal, per week, per quarter.

The window to learn this and stay competitive is 12–18 months. After that, buy boxes, funder rates, and merchant expectations will have adjusted around the operators who have the stack. New entrants without it will be starting a race that's already three laps ahead.

The readers who build this (or join someone who's already built it) win the next five years. The ones who don't, watch.
