Every time you open Business Kit

Your dashboard tells you what matters, not just what you entered.

Who to follow up with
Overdue invoices surface first, with the client and how many days overdue.
What's still owed to you
The exact total you're owed, without pulling up every invoice one by one.
Your upcoming deadlines
What's coming up or already past due, before it becomes a problem.
Missing receipts
The paperwork you're still missing, flagged automatically — never found too late.

You enter the information once. Business Kit tells you what to look at.

The problem

The daily reality of running a small business, scattered everywhere.

Invoices scattered across files, emails and notebooks.
Clients to track with no clear list of who owes what.
Payments received that you have to check and reconcile by hand.
Expenses noted nowhere, found too late.
Deadlines and slip-ups that cost you time or money.
Information scattered across tools that don't talk to each other.

Business Kit brings it together — and shows you what to do with it.

What's included

Everything you need, nothing you don't.

"Needs attention" dashboard
The prioritized list of what needs you: overdue payments, what's owed, upcoming deadlines, missing receipts.
Income
Log every payment received, by client and by service.
Expenses
Track your outgoings as they happen.
Invoices
Create invoices and mark them paid in one click — the matching income entry is created automatically, no double entry.
Clients
A simple directory to keep track of who's who.
Deadlines
Keep a clear view of what's coming up.
Receipts
Keep all your supporting documents in one place.
Backup / restore
Export all your data to a single file, restore it anytime.
Your data

Stored on your device, not on a server.

SENTARA Business Kit runs entirely in your browser (local storage). There's no cloud and no automatic sync across devices in this version.

A built-in export/import (backup) feature is included. It's important to use it regularly: if you clear your browser cache or switch devices without exporting your data first, it won't be available on the new device.

Always keep a recent backup somewhere safe.
