Local-first freelance/solo-agency management app
Your whole business in one file you own

One-time £24.99 · Yours to keep · macOS & Windows
Everything in one place
Run the whole business from one app
One tool replaces the stack of subscriptions freelancers and small studios juggle — and it all works offline.
Projects & delivery
Run projects in list, board or Gantt timeline views. Assets and tickets carry renewal alerts for domains, hosting and retainers.
Tasks & time tracking
Tasks with subtasks, recurrence, estimates and inline time tracking — so what you deliver and what you bill always line up.
Proposals & invoices
Branded proposals exported to PDF, then converted to invoices. Invoices are records-only — log an external Stripe or Xero number and issue a PDF.
Optimise auto-scheduler
Deterministic maths — not AI — reshuffles open tasks around your meetings and Google Calendar to hit deadlines. It proposes a plan; nothing changes until you Apply.
Calendar & email
A cross-entity month and week calendar with two-way Google Calendar sync, plus a multi-persona IMAP/SMTP inbox with per-client activity logs and reply threading.
Goals & milestones
Set a target number by a date, or a milestone checklist whose steps auto-tick as the linked projects and tasks complete.
Custom channels & fields
Build your own areas from Record, Task and Ticket archetypes with custom fields, and run multiple brands from one workspace with the multi-persona system.
SEB — voice & text butler
An on-device speech-to-text and text-to-speech butler. A regex skill router runs instant, £0 voice actions; bring your own Claude key or a local Ollama model for the rest.

Why SEBcentral
Own your tools. Own your data.
Built for independent professionals who are done paying rent to their own software.
You own your data — literally one file
Your whole business lives in a single SQLite file on your disk. Back it up by dragging it to Dropbox. Walk away any time with everything intact. No account required.
Buy once — no subscription
One payment and the app is yours, with free updates through the stable release. No recurring bill, no lock-in — the software and your data stay yours for good.
Privacy by design
Credentials are encrypted at rest via your OS keychain and bound to your machine. Email attachments are never stored. AI can run fully local for £0.
All-in-one
One app replaces your separate CRM, project manager, invoicing tool, calendar and inbox — with none of the monthly bills or data scattered across servers.
A voice butler that does real work
SEB runs on-device with a regex skill router for instant, zero-cost voice actions — plan your day, check what is overdue, log time — not a gimmick chatbot.
Cross-platform & safe by default
macOS (Intel and Apple Silicon) and Windows. Automatic pre-upgrade backups, atomic migrations and a downgrade guard keep your workspace safe.

Questions
Frequently asked
Where is my data stored?
Everything lives in a single SQLite file on your own machine — clients, deals, projects, tasks, money, calendar and email records. Heavy content like files and email attachments stays in your filesystem as pointers. Back it up by copying one file.
Do I need an account or an internet connection?
No account is required and SEBcentral works fully offline. You bring your own credentials for email and Google (your own OAuth app or app-passwords) — SEBcentral is not a central data broker.
Can SEBcentral charge my clients or process payments?
No. SEBcentral is not a payment processor. Invoices are records-only: you log an invoice and its external Stripe or Xero reference and produce a PDF. The app never charges cards or moves money.
Is there multi-device sync?
Multi-device sync is in development. Local mode is the default and the only fully-live mode today, so your workspace lives on one machine.
How does the AI and voice work — and what does it cost?
The AI and voice layer is opt-in and bring-your-own. The £0 path is either the on-device regex skill router or a local Ollama model. Using Claude is on your own API key. There is no bundled hosted AI.
Is it a subscription? What do I pay?
It is a one-time purchase — a limited-time early-bird price to own this version outright. No subscription, no account. Your purchase includes free updates up to and including the stable release, and the app and all of your data are yours to keep forever.
What if it’s not for me?
There is a 14-day, no-quibble refund from the date of purchase — if SEBcentral is not for you, email us within 14 days and we will refund you, no questions asked.
Which platforms are supported?
macOS (Intel and Apple Silicon) and Windows.
