AI modernization for field-to-finance operators. The machine drafts; a person signs.
The machine drafts.
A person signs.
Hearth builds AI systems for the finance workflows oilfield and credit teams still run by hand — field tickets, credit reviews, portfolio rescreens, AR. Our systems do the reading and the drafting, then stop and wait for your people. This page works the same way: it is a document, it halts at the decision, and before it ends it will ask for your signature.
Findings, before promises.
Hearth Advisory is a small firm with a narrow claim: the highest-value AI work in traditional industry is not chat, and it is not magic. It is the patient conversion of manual paperwork — tickets, memos, rescreens, invoices — into systems that draft well and defer properly. We audit one workflow, build the system, and hand it over. These are the conditions under which we are usually hired:
- 01Credit reviews assembled by hand from PDFs, spreadsheets, and email threads.cost: evenings
- 02Field tickets keyed twice — once in the field, again in accounting.cost: Fridays
- 03Portfolio rescreening done annually, because it takes a quarter.cost: surprises
- 04A website neither buyers nor AI answer engines can actually parse.cost: invisibility
One workflow, run in front of you.
We do not publish invented case studies, so our proof is drafted live. Below, a synthetic field ticket is read, checked, and turned into a draft credit note — then the system does the most important thing it knows how to do: it stops.

What Hearth builds.
Three schedules, one system. The audit finds the workflow; the build ships it; the web layer makes the firm legible to the buyers — and the answer engines — who go looking.
Field-to-finance workflow automation
Credit reviews, ticket-to-invoice, AR follow-up, portfolio rescreening — drafted by the system, decided by your analysts. Human gates are designed in, not bolted on.
- credit memos
- JIBs
- field tickets
- rate sheets
- aging reports
- counterparty exposure
- OpenInvoice
Sold as: a fixed-fee workflow audit first. You keep the map either way.
AI visibility
AI recommendations are the new front page. When a buyer asks ChatGPT or Perplexity who to call, we make sure your firm is understandable, citable, and present — measured quarterly, in plain numbers.
- AI recommendation audit
- visibility score
- entity & schema fixes
- quarterly readout
Sold as: an AI visibility audit with before/after evidence.
AI-ready websites
A site both a purchasing manager and an answer engine can read. Built the way this paper is built: fast, parseable, honest about what it claims — and it prints.
- no trackers by default
- structured data
- loads on field wifi
- credible to a CFO
Sold as: modernization of the site you have, or a rebuild with the visibility work of Schedule 2.
Who this paper is addressed to.
-
Oilfield & energy services
Service companies with real field operations and a back office that runs on spreadsheets and resolve. Houston-adjacent by design.
You recognize yourself if a ticket touches four hands before it becomes an invoice.
-
Industrial service firms
Inspection, rental, maintenance, logistics — businesses that quote, dispatch, invoice, and chase, mostly by hand.
You recognize yourself if the person who knows the process is also the bottleneck.
-
Credit & fintech teams
Credit, AR, and portfolio-risk groups that need drafts they can defend — with the reasoning attached and a person on every decision.
You recognize yourself if the annual review season has its own dread.
How an engagement runs.
-
Audit two weeks, fixed fee
We sit with the people who do the work and map one workflow end to end — every handoff, every rekeying, every judgment call. You keep the map whether or not we build.
-
Build weeks, not quarters
We build the drafting system with the holds where your judgment lives — like Exhibit A. Your team reviews real output from week one, on your data, under your rules.
-
Handover you own it
Runbooks, training, and the keys. We hand over; we don’t hover. A maintenance retainer exists for those who want it — it is optional on purpose.
A hearth is a contract with fire.
Fire was never the invention. The invention was the structure that made fire safe enough to keep indoors: stone, threshold, draft. Terms, in other words. The hearth is humanity’s oldest service agreement — heat, in exchange for containment.
AI is the new fire. We do not sell the fire.
We write the terms it lives under.
That is why our mark is not used as a logo on this paper but as a seal. Logos decorate products. Seals commit their maker to what the document says. The arch holds the ember; the firm holds the claim.
The firm.
Hearth Advisory is led by a credit and portfolio-risk professional who has written the memos, run the rescreens, and sat through the annual-review seasons this paper describes. The firm is small on purpose: senior attention on every engagement, no handoff to a bench. We build with modern AI tooling and an old habit — showing our work.
Appendix B — Terms of candor
- B.1No unsourced ROI numbers, here or anywhere. If we quote a figure, we show its working.
- B.2Every example is labeled synthetic until a client agrees, in writing, to be named.
- B.3We decline work where AI shouldn’t make the call — and we will tell you when a spreadsheet is enough.
- B.4Your data is not used to train public models. Ever.
- B.5Every system we ship halts for a human at the decision. This is an architecture, not a setting.
Reply slip — request the audit
