Nothing falls through the cracks — and you're no longer the one holding it all together.
Most owner-led teams run on a patchwork of disconnected apps — and the owner ends up as the glue. SEDER ONE replaces the sprawl with one system that does the admin a back office would, so nobody on the team has to be it.
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, you take payment online through your own Stripe, 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.
Start free with the basics, then switch on any of 70+ blocks — stock, a booking diary, the books — when you actually need it. You never pay in complexity for features you don't use; a traditional ERP ships all of them whether you use them or not.
One connected record
Records that know about each other.
Not just shared data — a live graph. Open any record to see everything linked to it, and when something changes the related records feel it, with a suggested next step. The thing a stack of synced apps structurally cannot do.
Right-sized power
Serious depth, without the enterprise 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 connected record |
| When something changes | Update each app by hand | Ripples to related records, suggests next step |
| Leaving | Painful migration | One-click export, self-host |
| Price | Enterprise contracts | Only what you switch on |
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 actions across the platform, double-entry accounting and VAT — built for accountability from the ground up.
Isn't that just what integrations between my apps do?
No. Integrations copy data between separate apps and drift the moment one side changes. SEDER ONE keeps one record every module shares — so a customer, a product or a payment exists once and is genuinely the same thing everywhere, with related records kept in step and the next step suggested for you.
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. On Premium you can even define your own relationships between records, no code.
Stop being your own back office.
One system, one shared record, only the modules you need — and your data is always yours.
