Inventory software that will always run on your own machine.
Your data lives on your own machine, you can keep writing orders with no internet, and one payment makes it permanently yours. Cloud deployment is available too, with server costs billed separately — and you can move between them later without replacing the system, retraining your staff, or migrating your data again.
It is not only yours. We can shape it around the way your business actually works.
Try it live in your browser, anytime · No install needed
- Billed monthly, access ends when payment does
- Your data lives on the vendor's servers
- One-time purchase, yours for good
- Your data stays inside your building
You didn't choose wrong. The rules changed.
Every line below comes from the vendors' own announcements and documentation. These were good tools in their day — the paths to keep using them are just being closed off, one by one.

The local version isn't sold to new customers anymore
In the US, Intuit stopped selling QuickBooks Desktop Pro Plus / Premier Plus / Mac Plus to new customers on Sep 30, 2024
MasterQ Inventory: always buy-once, still buy-once
3 yrs
Old versions get sunset, on schedule
QuickBooks Desktop sunsets each version on a ~3-year clock: the 2023 version is set to lose support May 31, 2026, and the 2024 version (the last retail release) is expected to lose support Sep 30, 2027
MasterQ Inventory: lifetime updates, no expiration date
10GB
Fill up the local database, it just stops
inFlow's on-premise edition caps out at 10GB when running on SQL Server Express / LocalDB — hit that and you can't add new data
MasterQ Inventory: no cap, hundreds of thousands of SKUs, still instant
up to 70%
Two rounds of price hikes in one year
QuickBooks Online raised prices 15%-25% across the board in May 2026, then Plus jumped to $140/mo (+41%) and Advanced to $340/mo (+70%) that August
MasterQ Inventory: buy once, tiered by user count, and that's the last bill you'll ever get

"Custom" means we haven't built it, but we can build it for you — scoped and quoted against your requirement. We are not a standardized SaaS serving hundreds of thousands of customers, which is why we can change the software at all. But changes cost time and money, and we won't wave "custom" around as if everything were free.
Native desktop apps for Windows and macOS, plus a browser version, all on the same live data. This table reflects the product as it actually stands. If something you need is marked custom, contact us and we'll tell you how long it takes and what it costs — and if your business genuinely can't run without something we haven't built, we'll tell you plainly that now isn't the right time.
Ready to switch, but worried about what breaks?
For owners who already want to switch, the sticking point is rarely "should we" — it's "how do we do this without something going wrong." Here's how we actually run it.
From kickoff to cutover: nothing switches until you say it's ready
- 1
Move your data first
Products, customers, vendors, and opening receivables/payables. QuickBooks Enterprise 2024 imports free and self-service; we assist with other versions.
- 2
Run both systems for 1–2 months
Your business keeps running on the old system — it stays the book of record. The new one is installed alongside with your data loaded, so staff can work with real products and customers: writing test orders, checking stock, running a count. Problems surface now, not on go-live day.
- 3
We customize during that window
Whatever feels wrong or doesn't match how you work gets fixed during the pilot — not patched after you've gone live.
- 4
You give the word, then we cut over
Not when we think it's ready — when you confirm it is. We're on site on cutover day (travel billed to the customer).
Why 1–2 months? Because the real risk in switching systems isn't the software — it's the dozens of details in your business that nobody outside it knows about. The pilot is the time to find those details and build them in. Discovering them on go-live day costs something else entirely.
"Can I still look up the price I quoted this customer two years ago?"
What happens to your history
- Standard migration covers products, customers, vendors, and opening receivables/payables
- Historical order line items can be imported — quoted separately. That two-year-old price comes with you
- QuickBooks Enterprise 2024 data imports free and self-service
- After go-live, export everything to CSV / SQL at any time — nothing is locked up on our side
"My people know the old system by heart. What if they can't learn this one?"
What happens to your team
- The 1–2 month pilot is the training period — nobody starts learning on go-live day
- The interface runs in both English and Chinese and switches on demand — the owner reads Chinese, the warehouse and drivers read English, same system
- Features you don't use can be removed; a simpler screen is a faster one to learn
- Call or message with a question and you reach the person who writes the code — no waiting on email
"What if you're not around in a few years?"
What happens long term
- A perpetual license written into the contract, not promised verbally
- Source code held in third-party escrow: if we cease operating, the source is yours
- On-premise keeps running with no internet — and even if you can never reach us again
- Export all of your data to standard formats at any time. No lock-in of any kind
We serve a small number of customers, and we can't afford to get a single one wrong — which is both the thing you should worry about and the reason you can relax.
We won't pretend buying outright is always cheaper. The first years are a real investment. But subscriptions have no bottom; ownership has an end. Here's the honest math:
Taking QuickBooks Enterprise and inFlow Mid-Size as examples — an honest 5-year tally (see your actual quote)
QuickBooks · Enterprise Silver subscription
From $1,873 / yr (1 user; no buyout option since 2023)
- Year 1
- ≈ $1,873+
- 5-year total
- ≈ $11,000 ~ 14,000+
- On-premise / data
- Rented, not owned — 12-month read-only after lapse, then locked out entirely
- Yearly increases
- The norm — multiple tiers rose 10-15% in Feb 2026
New customers don't even get a buyout option anymore — subscription only
inFlow · Mid-Size subscription
$699 / mo (≈ $8,400 / yr)
- Year 1
- ≈ $8,400
- 5-year total
- $42,000 ~ $60,000+
- Add-ons / API
- Extra cost
- Yearly increases
- Likely
Stop paying = stop using. After 5 years, nothing to show.
MasterQ Inventory · one-time purchase
Quoted by edition, user count, and customization; on-premise is bought once, cloud server cost billed separately
- Year 1
- One-time purchase, installments available
- Years 2–5
- $0 (optional annual maintenance)
- On-premise / data
- Yours forever
- Yearly increases
- Never
Pay once = own forever. The software and data are your assets.
Both subscriptions run at least $11,000 over 5 years, and they're still paying every year after that; our standard edition is already at zero cost by then — fully yours. The longer you run it, the more you win.
It shows you money, not paperwork.
No digging through paperwork, no waiting for month-end. MasterQ Inventory tells the boss, right on the home screen —
Good morning. Here's your day, sorted out:
$0
Actually earned from today's sales (cost deducted)
$0
Tied up in stock — $5,000 of it hasn't moved in 30 days
$0
Owed by customers — 2 invoices overdue, worth chasing
Three numbers, three meanings — never blurred together. This is the account MasterQ Inventory settles for you every day.
Reach out for a free demo and assessment. QuickBooks Enterprise 2024 data imports free, self-service; other versions or assisted migration (items/customers/vendors + opening receivables/payables) start at $300–600 depending on volume, with historical order detail available for a separate quote. Your data is loaded within days — then the system runs as a pilot for 1–2 months, and we only cut over once you confirm you're ready.

About Us
Allen Zhang
Founder — building and supporting this myself
The ERPs I used to work on ran into the millions of dollars and took a year or two to go live. But a small business isn't that complicated — the owner needs a clear view of stock, money, and customers, not a system that takes a consultant to switch on. So I've long wanted to build a simple, direct ERP that a small business could actually afford.
Over 20-plus years I've managed teams of more than a hundred and worked on projects staffed by a hundred-plus engineers: the billing management system for Jiangsu Mobile, CRM + ERP for several universities in China, and the CRM + ERP built for Laureate Education's multinational university network. I'm a former HP, SAP, and EY engineer, and I've delivered alongside teams from Oracle, Microsoft, and Accenture. I list these to make one point, not to show credentials: telecom billing and multi-continent ERP are considerably harder than an inventory system. I know how systems that handle money, stock, and reconciliation should be built — and where they tend to break.
I've also built systems independently across industries: ERP for a print shop, ERP for a medical clinic. Very different businesses, one same approach — build around how you work, rather than making you bend to the software. So "customizable" isn't a promise here; it's something already done many times over.
