One system, one record, no lock-in.
Most growing businesses run on a patchwork of disconnected apps — and become the integration themselves. SEDER ONE replaces the sprawl with one platform you assemble from blocks.
A business past its first few people runs on tool sprawl.
- ×A spreadsheet for stock — or no stock system at all.
- ×One app for invoicing, another for quotes, a booking tool for the calendar.
- ×Receipts and bills in an inbox; the accountant reconstructs reality months later.
- ×Customer information in three places, none of them agreeing.
- ×The owner as the human integration layer, re-typing the same numbers between apps.
Full ERPs don't fit
SAP, NetSuite, Odoo, Dynamics — built for enterprises. Heavy, expensive, months to implement, hundreds of screens you'll never use.
Point tools multiply
Easy to start, but they multiply into the exact sprawl the business is trying to escape — a new bill and a new silo each time.
The gains, in plain terms.
Fewer tools, one bill, one login
Replace a stack of six-to-ten subscriptions with a single platform — less spend, fewer integrations to babysit, one place for the whole team.
One source of truth
One contact list, one catalogue, one ledger — shared by every module. The customer you invoice is the one you schedule, ship to and support. Nothing drifts.
Cash comes in faster
Quotes convert to invoices in a click, customers pay online, and overdue invoices chase themselves. Less time between “done the work” and “money in the bank.”
The books keep themselves
With accounting on, every invoice, payment and expense posts to correct double-entry ledgers automatically — with VAT and bank reconciliation, and a live P&L.
Real visibility
A live dashboard and cross-module reports answer “how are we doing?” on demand — the data is all in one system, already connected.
Grows with you, not against you
Start with the foundation; turn on inventory, projects or POS when you need them. It expands one block at a time — no migration, no re-training.
Four things we always come back to.
Composable, not bloated
Only run what fits your business.
Assemble from 45+ blocks and turn modules on as you grow. Never pay in complexity for features you don't use — a traditional ERP ships all of them whether you use them or not.
One shared record
Enter it once. It's everywhere it should be.
One contact list, one catalogue, one ledger, shared by every module. No re-typing, no reconciling, no drift — the thing a stack of point tools structurally cannot do.
Right-sized power
An ERP's reach, at a tool's weight.
Real operations depth — stock, scheduling, projects, job-costing, double-entry books — without enterprise cost, months of setup, or screens you'll never open.
Yours to own
Your data. Your platform. No lock-in.
Full one-click export, hosted or self-hosted, role-based access, and a complete audit trail. The confidence of a platform that earns its keep every month.
Against the alternatives.
All the depth, none of the enterprise weight or cost — you'll never see a screen you didn't ask for.
One system with one shared record, instead of five tools you reconcile by hand.
The graduation from spreadsheets — without becoming a project.
| The usual way | SEDER ONE | |
|---|---|---|
| Setup time | Months of implementation | Minutes from a template |
| Shape | Every screen, used or not | Only the blocks you turn on |
| Data | Synced between apps | One shared record |
| Leaving | Painful migration | One-click export, self-host |
| Price | Enterprise contracts | Assemble what you need |
The questions we get.
We already have QuickBooks / Shopify / a booking app — it works.
Each works alone — but you're the glue, re-typing and reconciling between them. SEDER ONE makes them one system with one record, and usually replaces several bills with one.
Isn't an all-in-one going to be bloated and hard to use?
Only if it shows you everything. SEDER ONE shows only the modules you turn on, so it stays as simple as the business needs — and grows one block at a time.
ERPs take months and a consultant to set up.
Not this one. Pick an industry template, load sample data, import your CSVs, invite the team — you're running a real system the same day.
What if we want to leave, or outgrow it?
One-click full export, and it can be self-hosted. Your data is always yours — leaving is a button, not a battle.
Is it secure and auditable enough for our books?
Role-based access, an append-only audit log of every action, double-entry accounting and VAT — built for accountability from the ground up.
Can it handle our specific fields and workflow?
Custom fields on any record, and a module set you shape to your trade — it bends to your business, not the reverse.
Stop buying tools. Assemble one system.
One platform, one shared record, only the modules you need — and your data is always yours.
