The engine under the products.
AVNZ runs the parts a small business never wants to build. Checkout and billing, the funnel that leads to it, every lead that comes in, the customer service that answers, the ads that buy the traffic, and the mail that starts the whole thing. Each product below is a door into the same machine.
AVNZ is a GG Consulting company.
Never let a model invent a number.
Every other product in this category leads with how much its AI reads. Ours leads with what it is forbidden to touch. A vision model that reads $54.99 as $549.90 with total confidence poisons a tax return silently, and nobody finds out for a year. That single failure is what the whole architecture is built to make impossible.
| Step | What runs it | Why |
|---|---|---|
| Amounts, dates, vendors | Purpose built extraction | Not a language model. It reads layout and returns typed fields with per field confidence, so it does not generate a figure and structurally cannot invent one. |
| Arithmetic validation | No model | Line items sum to the total, tax is plausible, dates fall in period. Deterministic and testable. |
| Categorization | Small classifier | Genuine judgment, so a model earns its place here. Constrained to a fixed taxonomy and the practice's own history, which is where the accuracy actually comes from. |
| Findings and detection | No model | Duplicate charges, price creep, stale subscriptions. Found by arithmetic with thresholds you can read, which is why every finding can be defended. |
| Phrasing the finding | Language model | Language only, over a result that is already true. It never sees a raw transaction and never decides whether a finding is real. |
| Hard pages, low confidence | Vision model | Fallback only, never the default path, and every document that takes it is flagged as having done so. |
Tier scales with judgment required rather than with importance. The most important step in the chain gets the least generative treatment, which is the opposite of how most of this is built.
Every call on the record
Prompt version, tokens, cost, latency, and outcome, written for every single call. It is how prompts get tuned without guessing, how a bill is explained line by line, and what an auditor is shown when they ask how a number was reached.
Nothing fails silently
Work that cannot complete lands in a tiered queue rather than vanishing, retried, escalated, and finally put in front of a person. Each step carries forward why the one below it could not finish, so an escalation arrives as evidence rather than as a shrug.
A vendor's bad afternoon stays small
If the cheap tier starts failing at scale, the ladder stops escalating and pages instead. Without that circuit breaker an upstream outage quietly converts every document into an expensive call, and one bad afternoon becomes a runaway spend event.
Computed, never generated
The machine computes and the model speaks. Findings come from arithmetic over the ledger; the model writes the sentence that explains one. It is the difference between a number you can defend to an auditor and a number that sounded right.
Eight systems, one spine.
Not a roadmap. These are the modules the products above are built on, described by what they do rather than what they are called.
Take the money
Checkout, subscriptions, and recurring billing, with refunds that route through an approval step and chargebacks handled before they turn into write offs. Four gateways sit behind one interface, Stripe, PayPal, NMI, and Authorize.Net, so a card declined in one place can be retried in another.
Build the path to the sale
Multi stage flows from a first click to a paid order, with A/B variants, session tracking, and recovery for the carts that get abandoned along the way. Assembled and changed without a developer.
Catch every lead
Web forms, text in keywords, and printed QR codes all land in one inbox, deduplicated, with the ad click that produced them attached. Every lead carries a status until it reaches a real outcome, and anything that sits untouched for three business days gets flagged rather than quietly forgotten.
Answer the phone
Voice and chat handled by an AI representative that escalates to an AI manager, and then to a person when the situation earns it. Wired through Twilio, so the number rings for real and the transcript is kept.
Buy the traffic
Google Ads campaigns built and managed, with a copy lab for headlines and descriptions, and offline conversion upload wired back to Google so bidding is built to train on what actually closed rather than on what merely got clicked.
Send the message
Transactional email on a queued and logged sender, SMS keyword capture that turns a printed code into a contact, and lifecycle sequences that fire on their own schedule and then stay out of the way.
Hold the keys
Every third party credential encrypted with AES-256-GCM and configured per provider in one place, never scattered through environment files. The server refuses to start without its encryption key, which is the point.
Put it on paper
Personalized letters with a unique code for each recipient, a print pipeline that renders and sorts them for postage, and per code scan tracking so a piece of paper becomes something measurable instead of something hoped for.
Every product is a door into the machine.
Each one is built for a trade that would never shop for software. The machine underneath is the same.
SheetTamer
For accounting practices and the businesses they serve. Documents land in a shared room sorted by month, the practice asks for whatever is missing with one click, and a checker reads the workbook for duplicate charges, price creep, and invoices past due.
sheettamer.com
Free for accounting practices.
AVNZ Leads
For local service businesses. Ads managed, every lead captured and answered, and a weekly report that shows the cost of a booked job rather than the cost of a click. The software is finished and deliberately closed until the first door reads out.
leads.avnz.io
Goes to a person, not a list.
ShipKeeper
For anyone who ships. A customer portal for filing a claim, a workflow that moves it without email, risk scoring on the claims that do not add up, and billing that reconciles itself. Software for handling what goes wrong in transit, sold as software.
shipkeeper.io
Runs standalone or inside a store.
Commerce
The original spine, and still the largest. Funnels, checkout, subscriptions, orders, refunds, fulfillment, and the routing that decides which processor sees a card. Every other door is built on parts of it.
admin.avnz.io
Sign in required.
cpa.avnz.io · payments.avnz.io · sb.avnz.io are divisions on the same machine. They open when there is something behind them worth walking through, and not before.
Shared underneath, separate at the door.
A business that uses two of these never sets up billing twice, and a lead that turns into a customer keeps its history instead of starting over.
Building something that belongs on these rails?
If you run a trade, an agency, or a book of clients that needs the machine rather than another dashboard, say so plainly and we will answer the same way.
