Your business records live in five different places
Sales in a notebook, stock in Excel, cash in another program, orders on WhatsApp. Prefux is a software company that builds cloud software to end this fragmentation for businesses.
You pay the bill for that fragmentation every single day
The problem isn't a missing program; it's programs that never talk to each other.
You enter the same data twice
The sale in one place, the stock deduction in another, the payment in a third. Every repetition is another chance to get it wrong.
You wait until closing time
You only find out what you made today when you count the till in the evening.
The count doesn't add up
When stock and cash are kept in separate ledgers, "where did this difference come from?" has no answer.
Knowledge stays with one person
One person knows the prices and who owes what. When that person leaves, the knowledge leaves too.
A business should have one record
A sale is entered once; stock, cash and reports update themselves. We treat this not as a feature but as an architectural decision: modules never call each other directly, they communicate through events inside the same transaction. So if the stock wasn't deducted, the sale didn't happen either — there is no such thing as a half record.
No deleting, only correcting
Stock and money are never set by hand to "make it 50"; every change produces a movement record. The past cannot be rewritten and can always be replayed.
Your data in your own database
Not a row filter on a shared table, but a separate database per company. Per-company backup and restore follow naturally from that.
Permissions on the server, not the screen
Hiding a button is not security. A cashier works with a cashier's permissions — whichever screen they try it from.
Who changed what, and when
An audit trail with before/after values. Audit rows in your business records are linked to one another with a hash chain, so a row altered after the fact becomes visible.
Two steps at sign-in
TOTP-based multi-factor authentication, a per-device session list and remote sign-out. Passwords are stored with Argon2id; passwords found in known breaches are rejected at signup.
Browser and pocket at once
Both Android and iOS from a single codebase. No installation, no versions, no update chores.

Proof instead of reference logos
This page carries no customer logos, no award badges and no "thousands of businesses" — because we don't want to invent something to show. Here is what we can show:
- We wrote down item by item how we delete your account and your data — which data is erased and which is kept for legal reasons. Account deletion →
- Your card details never sit with us — subscription payments are taken on iyzico's secure page.
- Our security posture is written out point by point — isolation, permissions, audit trail, password storage. Security →
- A 7-day trial without a card — if you don't like it, you owe nothing.
