You do not need more software.
You need to stop renting it.
DeskSentry is a machine that sits in your business and runs your back office. It reads the paperwork, files the jobs, keeps the customer records, and tells you where the money came from. You buy it once. Nothing leaves the building.
The flower shop, the detailer, the HVAC crew — if your business runs on paperwork, it runs on this.
No cloud · No subscription · No data hostage
Sitting on a shelf in the business. Not in someone else's data center.
Right now you're renting your own business.
Every tool that touches your customers, your invoices, and your job history belongs to somebody else. Stop paying and it locks you out. That's not a service — that's a leash with a monthly fee.
And on the day you stop paying, you own none of it.
Five years of renting your back office at $1,650 a month. At the end of it, you still do not own a single record.
Rented figures are the real market rates above. Builds start at $3,000; $7,500 is a mid-size shop with a few years of paperwork to load in. Yours is quoted to the job, and the slider is there so you can put your own number in.

The parts of the job nobody wants to do at 9pm.
The intake brain
Your paperwork flows in the way it already does — email, scans, texted photos — and the machine reads it, figures out the customer and the job and the dollars, and files it. Ask for “everything on the Henderson furnace job” and it's just there. Put ten years of information in; it's organized by morning.
Customer records that build themselves
Every customer gets a file automatically — no CRM to set up, no fields to fill in. Every document, every dollar, every job, rolled up the moment paperwork comes in. The customer database most software makes you build by hand, here for free as a byproduct of just doing the filing.
Quotes & invoices
Write a quote, print it or email it, and turn the accepted one into an invoice without retyping a thing. The office tracks who owes what, flags overdue on its own, and records how they paid — cash, check or card. Your terms print on every one.
Jobs & service plans
Today's work on one screen, and the recurring work that pays the bills handled for you — tune-ups, seasonal visits, standing service. The box brings each one up before it's due, books the job, and rolls the date forward. It remembers the equipment on every site too, and how old it's getting.
The dates that bite
Permits waiting on inspection, insurance certificates about to lapse, warranties worth registering. The box watches them and puts them in front of you before they expire — and it spots them in the paperwork you file without being told.
Books your accountant will take
Connect your banking information and deposits line up against unpaid invoices — you confirm each match, nothing is guessed. This creates a folder your CPA actually wants: balanced books, profit and loss, and every receipt attached. Not a login you have to hand them.
Calls & texts
Connect a business phone number and the box answers it. It takes the caller's name, what they need and a callback number, then files the message — it never quotes a price or promises a booking. Texts land the same way, and a photo texted in gets read and filed like anything else. The number is yours, on your own phone account.
It speaks up first
A short brief each morning: what needs your eyes today. Overdue invoices chased politely, quiet quotes followed up, a thank-you when someone pays. And service reminders, personalized in your own words — “our records show your furnace is due. Want to set a time?” Every one of those is a switch you turn on, and it's off until you do.
Shop insights
Because everything's filed, the machine can finally answer the real questions: what you invoiced this quarter, which bids are still open, who your money actually comes from. Numbers straight from your own paperwork — not a report you have to build.
Three steps, and then you go back to work.
It shows up built
The hardware arrives configured for your shop. It plugs into power and your network. There's nothing to install, no account to create, no seats to assign.
Your history goes in
The files, the spreadsheets, the folder of scans, the shoebox. It gets loaded and read once, so on day one it already knows your customers.
It just runs
Send paperwork to it however you already send things. It files, it indexes, it backs itself up. Nobody has to learn a new system.
Nowhere. That's the entire feature.
Most "AI for your business" means your customer list takes a trip through three companies you've never signed a contract with. Here's the difference, drawn out.
Cloud software
DeskSentry
The questions everybody asks.
What if the AI misfiles something?
Nothing gets deleted or hidden — everything stays visible and searchable regardless of where it lands. Moving a misfiled document is a one-click fix, not a broken system.
What happens if the box breaks?
Hardware fails eventually — drives die, storms happen, things get dropped. The box is built to make that a bad afternoon instead of a catastrophe: your records are backed up on the box every night and kept two weeks there, with a copy held off-site for ninety days. They're your files either way — you can pull a copy off whenever you like, and a replacement box loads your office back from those backups by itself. The hardware carries a one-year warranty, and on the keep-it-running plan a standby box takes over on your same web address by the end of the next business day while we replace yours and restore your office. Bugs aren't hardware: defects in the DeskSentry software are fixed at no charge through the first year, plan or no plan.
I'm not a computer person.
Good. It's built for a business, not an IT department. It's installed and set up for you; day to day you send paperwork the way you already send it and ask questions in plain English. If you can text a photo, you can run it.
Am I locked in?
No. Nothing is hostage. Everything lives in an ordinary database and a folder of real files, on hardware you own — there's no export process to build because there was never anything locked away to begin with. Ask me to turn the software off and open the folder — every invoice and photo sits in a folder named for the customer, and the database opens in any free SQLite viewer and answers a plain query with DeskSentry completely stopped.
Does this replace QuickBooks?
Bookkeeping and payroll are regulated — tax filing, compliance, banking rules that tools like QuickBooks have spent decades getting right. Rebuilding that isn't the goal. DeskSentry organizes everything that feeds your books — invoices, receipts, job costs — and hands it over clean, in a folder your accountant will actually take.
What does it actually cost?
From $3,000, once — one machine, everything included: the box, your existing records moved in, setup and a walkthrough, and a one-year hardware warranty. A business with heavier work gets a bigger engine, and either way you get the exact number in writing before a single part is ordered. No monthly fee after. The optional keep-it-running plan is $25 a month or $250 a year: security updates and software fixes for as long as you keep it, an off-site copy of your nightly backup, remote hands when something's wrong, and a standby box on your same address by the next business day if yours dies.
What if DeskSentry goes away?
The box keeps working. Your records, your customer files and the AI itself are on the machine in your office, not on a server somewhere. The software that runs it is on that machine in plain, readable form — ordinary Python, an ordinary SQLite database, a folder of real files, open AI models — so any competent tech can open it, run it and keep it going without me.
Who's behind it?
Costa Customs L.L.C., Michigan. DeskSentry is built by a tradesman, not a software company — I spend my days in elevator machine rooms and built this because the back office was eating the evenings. It has been running in a working HVAC shop since August 2026: real customers billed, supplier invoices filed on their own, the phone answered. Ask for that owner's number.
You’ll know the price before anything gets built.
From $3,000 — one machine, everything included: the box, your existing records moved in, delivery and a walkthrough, and a one-year hardware warranty. It starts with twenty minutes: how many people touch the paperwork, how much of it comes in a week, and what you’re paying right now to keep up with it. Bring a stack of your own bids and invoices and I’ll show you what the box does with them. Then you get a real number in writing — sized to your business, quoted before a single part is ordered. If it’s not worth it, you’ve spent twenty minutes. If it is, DeskSentry arrives set up, with your existing information already moved in.
Keep-it-running plan, optional: $25/mo or $250/yr — security updates and software fixes for as long as you keep it, an off-site copy of your nightly backup, remote hands when something's wrong, and if the box ever dies, a standby takes over on your same address by the end of the next business day while we replace the hardware and restore your office. Nightly backups on the box itself are free forever, plan or no plan, and defects in the software are fixed at no charge through the first year either way.
In a world full of subscriptions, what do you actually own?
Your truck. Your tools. Your name on the door. Everything you’re proud of, you bought once and it stayed yours. Your office should be on that list — not one more meter running while you sleep.
DeskSentry is the back office you own outright. Bought once. Yours for good.
* Your records and the AI live on the box and keep working when the internet is down. Reaching the box from off-site — and features that talk to the outside world, like emailing a customer or answering a phone line — do need a connection.
