How the admin runs itself.
SEDER ONE is one application that becomes many. Every business starts with the same 19-module foundation, then switches on blocks from a library of 78 to match its trade — no migration, nothing new to learn.
One shared record
The modules aren't separate apps stitched together by integrations — they're rooms in one building, looking at the same data. One Contacts list is the customer in Quotes, the payer in Payments and the requester in Support.
Because there's one record, an event only happens once: a sale is simultaneously an order, an invoice line, a stock movement and a set of ledger entries — not four things typed into four tools.
Nobody re-keys the amount. With accounting on, correct double-entry entries — with VAT — post automatically.
Everything connects
One shared record isn't just tidy storage — it's a live web of relationships. Open any record and SEDER ONE shows everything linked to it, in both directions: the customer on an invoice, the order behind it, the jobs it paid for, the documents it generated.
It runs across the platform — invoices, quotes, orders, jobs, projects, contacts, purchasing and more. And with Data Studio (Pro), you can define your own relationships between records, no code required.
Every link is two-way and clickable — custom links flagged, so you always see the whole picture.
From zero to a working system
- 1
Set up the business
A first-run wizard captures the essentials — name, branding, currency, languages, tax profile.
- 2
Pick a starting point
Choose an industry starter template to switch on a tailored module set, or start from the foundation and add blocks by hand.
- 3
Load sample data (optional)
Templates can seed clearly-marked example records so you explore a working system, not empty screens. Removable in one click.
- 4
Bring in real data
Import contacts, products and suppliers from CSV using guided templates.
- 5
Invite the team
Add people, assign roles, and everyone signs in to the parts that are theirs.
The result: a business looking at a system shaped like itself, populated and navigable, in minutes — not the months a traditional ERP takes.
Built for the people who actually run it.
Roles & permissions
People see and do only what their role allows.
Audit log
An append-only record of who did what — accountability, and a clean story for auditors.
Custom fields
Add business-specific fields to any record, without code.
Documents
Every generated and uploaded file in one place, on the record it belongs to.
Languages & themes
Five languages, light/dark, per user — the platform meets each person where they are.
Personal dashboards
Each user arranges their own dashboard — the widgets and shortcuts that matter to their role.
What it is, technically — in plain English.
Enough for a buyer or partner who asks "what is it, under the hood?"
- A modern web application. Fast, browser-based, nothing to install — works on desktop and mobile.
- Your own isolated instance. Each business runs in its own dedicated deployment and database — the strongest isolation boundary, with its own data, branding and enabled modules. Operators and agencies run many of them as a managed fleet.
- Config-driven. Modules, currency, tax, languages and branding are settings, not custom code — so it's fast to stand up and cheap to change.
- Built-in data integrity. Records are joined by real relationships and every status is a real database enum — so impossible states can't be saved and the data stays trustworthy as it grows.
- Hosted or self-hosted. Run it for you or on your own infrastructure, on a current, well-supported stack with security and accessibility built in.
Your data is yours.
One click produces a complete, machine-readable export any time. SEDER ONE can be hosted for you or self-hosted — you're never trapped.
