Know your margin the moment time is logged
No more waiting three weeks after month-end to find out a client lost you money. Every entry updates revenue, cost and margin instantly — so you can act while it still matters.

- Spot accounts quietly running over budget
- Slice by work code to see which services pay
Capture every hour, the way your team actually works
Start a timer in a click, or add time manually after the fact. A short description against each entry justifies the bill and writes the client's report for you.
- One-click timers that roam across the app
- Manual entries for forgotten time
- Descriptions that double as your client report
Reports that make a retainer easy to renew
One click turns the month's logged time into a branded PDF showing exactly how every hour was spent — the proof of value that keeps clients signed up.
- Branded with your logo, not ours
- Broken down by work code with descriptions

Frequently asked questions
Everything you need to know before you dive into the demo.
How much does Fortis Time Management cost?
Solo is £9/user/mo billed annually (£11 monthly), Team is £15/user/mo annually (£19 monthly), and Business is £24/user/mo annually (£29 monthly) — all prices per user, excluding VAT, with no usage fees on projects, clients or invoices. Every plan starts with a 14-day free trial, no card required.
Do I need to install anything?
No. Fortis Time Management runs entirely in your browser, on desktop and phone. Your team signs in and starts logging time — there's nothing to download, and the live demo needs no signup at all.
Which accounting tools does it work with?
Xero today: invoices push straight to Xero as drafts — matched to the right contact, with line items in place — and your finance team reviews and sends from there. QuickBooks, Sage and FreeAgent are coming soon.
Can my team see each other's cost rates?
No. Internal cost rates stay private to owners and admins. Team members see what they need to log and report time, while your margins stay confidential.
Can I put my own brand on it?
Yes. Upload your logo in Settings and it appears in the app, on the client PDF reports you send and on invoice PDFs — ideal for agencies and firms presenting to clients.
How does billing work — by hour or by retainer?
Both. Set a client up on a monthly retainer, a fixed fee or time and materials, priced by type of work or by each person's charge-out rate. Fortis Time Management prices every logged hour automatically either way.
What happens to time once it's billed?
Approved hours are gathered into an invoice, grouped by project and rate with VAT applied, then locked so they can't be billed twice. Everything ties back to the work actually logged.
