The back office you don't have
The work is yours. The admin runs itself.
Get paid on time. Nothing forgotten. Your evenings back.
The problem
Nobody was hired to hold it together — so it fell to you.
Past your first few people, the business runs on a pile of tools that don't talk. A spreadsheet for stock, one app for invoices, another for quotes, a booking tool for the calendar, receipts in an inbox the accountant untangles months later, customer details in three places that disagree. Every night, you become the part that reconciles what the software couldn't — the human integration layer no one should have to be.
The idea
None of you should have to be the back office. So the software is.
You and your team do the work; the operational blocks do the admin a back office would — invoicing, chasing, stock, scheduling, the books. And because all of it lands on one shared record, nothing is re-typed and nothing drifts: a sale is at once an order, an invoice line, a stock movement and a ledger entry, entered once. Not a stack of apps you reconcile — one system that keeps itself.
What changes
What that feels like on a Tuesday.
Get paid without chasing.
Send the invoice and you're done: overdue ones are chased for you, and payments reconcile themselves.
Always know where you stand.
Your numbers are current, not reconstructed at quarter-end — margins, cash and what's owed, live.
Close the day with nothing waiting.
What needs you surfaces with the fix one click away; the rest is already handled.
How it works
Enter it once. It carries itself the rest of the way.
Enter it once.
A quote becomes an order becomes an invoice becomes a payment — nobody re-keys the amount at any step.
Customers pay online.
Checkout runs through a client portal; payments reconcile themselves; overdue invoices chase themselves.
The books post themselves.
With accounting on, correct double-entry entries — with VAT — post as you go, reconciled to the bank. A live P&L, not a quarterly reconstruction.
It tees up the next step.
When a record's state calls for action — stock hits its reorder point, a quote goes stale, a finished job is ready to invoice — SEDER ONE proposes the step and opens it pre-filled. You confirm; it never acts behind your back.
Right-sized, always
Fits you doing everything today. Still fits at twenty people.
Start free with the foundation, switch on a block when you actually need it — stock, a booking diary, jobs, the books — one thing at a time. 70+ modules, and your whole team is included: no per-seat, because you pay people to do the work, not the paperwork.
Shaped to your trade
Pick your trade. It's a working system in minutes.
Fifteen starter templates switch on the right blocks and load sample data, so you're exploring a real system in minutes, not a months-long project with an integrator. Product, service, recurring, hire or project — there's a shape for it.
Beyond the back office
Then it does the part a back office never could.
Once everything lives on one record, a second layer sits on top — the intelligence a back office would never have produced. SEDER ONE reads across all of it and tells you what to do next: where your margins really are, what's about to run short, which customers are slipping. No hire ever read across your whole business at once. This one does.
Trust & control
It handles your money and your books. So it earns the trust.
Role-based access
Everyone sees and does only what their role allows — everyone in their lane.
Append-only audit log
Entries record who did what and when, and no individual entry is ever altered or removed.
