Your money — which pile of
stock is it hiding in?
A whole year of work, yet you can't say if you made money. MasterQ settles it on your home screen daily: what you earned, where it is, what to restock, what to stop.
30-day free trial · Money back if unsatisfied
It shows you money, not paperwork.
Others drown you in purchase and sales line items. MasterQ 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 settles for you every day.
Going further: not just clarity — we help you earn more.
Where to invest more
See which products and customers are most profitable, and put your money where it grows.
💬Power tools ran a 42% margin this month on 380 units sold — your top earner. Time to stock up.
Where to pull back
Spot goods that are sleeping and tying up cash, so you stop over-ordering.
💬These 18 SKUs haven't moved in 60 days, tying up $14,200 — consider clearing them or pausing orders.
Faster stock & cash turnover
Smart restocking turns goods and cash faster — more business on the same capital.
💬At the last 30 days' pace, Class-A stock lasts 9 more days. Order today, arrives in 3 — no stockout, no pile-up.

Why MasterQ is different
Same inventory software — the difference isn't how many features, but whether your data is safe, whether it fits your business, and whether you can reach someone.
Local data · no forced cloud
Permanent on-premise or LAN install — the database lives in your company, your books untouchable.
On-site local service
Our team comes to customize, install and maintain, in your language — someone's always reachable.
Custom-fit, 100%
Not off-the-shelf — built to your workflow, every requirement delivered.
Daily profit insight
See this month's gross profit, margin, receivables, returns impact, top products / customers right on the home screen.
Auto-priced invoicing
Tiered and special prices fill in automatically — no manual discounts, no misquotes.
Automatic stock in/out
Sales deduct, purchases add, returns reverse — and you see stock value and bestsellers.
Optional e-commerce
Add an online store on demand; each customer sees their own pricing.
AI smart queries
Just ask: "Who bought the most last month?" — instant answer, no reports to learn.
One-click migration · bilingual

Bookkeeping from a boss's perspective — no accounting knowledge needed. AI auto-matches tax formats
The headaches you face daily — solved, one by one
Built for wide-catalog wholesale & retail — hardware, plumbing, building materials, decor, tableware, electronics. No feature bloat, just what you use every day.
One product, priced any way — all calculated
Per-unit, by weight, by length, by volume, tiered, member pricing — even complex prices fill in at invoicing.
举个例子 Hardware store: the same steel pipe sold by the meter, by the piece, or quoted by the ton for big buyers — auto-converted, no mental math.
Hundreds of thousands of SKUs — found fast, no lag
Multiple specs and attributes per product; color/size/model combinations; instant response at huge scale.
举个例子 Electronics: the same AC in 1.5/2/3 HP, white/silver — scan or type to pinpoint the exact variant in two seconds.
Sells deduct, purchases add — stock is always right
Sales auto-deduct, purchases auto-add, returns auto-reverse; see cash tied per item and bestsellers.
举个例子 Building materials: sell 20 bags of cement this morning, stock instantly shows 80 — and the home screen flags a restock below safety level.
Many stores, many warehouses — one view
Independent management and transfers across stores and warehouses; see who has stock and who's short.
举个例子 Chain: Store A is out, Warehouse B has it — transfer with one click, no back-and-forth phone calls.
Who owes you, who you owe — crystal clear
Complete customer & supplier profiles, clear running accounts, receivables/payables and overdue terms at a glance.
举个例子 Wholesale: Mr. Zhang owes $3,200 this month, 5 days overdue — the chase list builds itself, no missed collections.
Trim what you don't use, add what you need
Not off-the-shelf. We'll strip features you don't use for a cleaner UI, and build the ones unique to you.
举个例子 Tableware wholesale: dual-unit stock by case/by piece doesn't exist elsewhere — we custom-build it, live in days.

= a stronger business that earns more the more you use it
They sell software, but charge you SaaS forever.
We sell service, yet let you buy it outright — an asset, not a rental.
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 inFlow Mid-Size as the example — an honest 5-year tally (see your actual quote)
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 · one-time purchase
From $50,000 (quoted to your customization)
- Year 1
- From $50,000 (one-time)
- Years 2–5
- $0
- On-premise / data
- Yours forever
- Yearly increases
- Never
Pay once = own forever. The software and data are your assets.
Comparable cost within 5 years; the gap opens up after — they keep paying yearly, you're already at zero. The longer you run, the more you win.
You choose, we don't force it
Monthly and annual are available too. Subscribe while budgets are tight, buy out once you've grown — whatever works for you.
Reach out and I'll give you a free demo and assessment, then migrate your old QuickBooks / inFlow data for free — live in just a few days.
