WatuFlex
Apps for the People

A complete business system that runs in your own building.

WatuFlex puts your school, your payroll, your accounts and your records on one machine in your own office — working at full speed with no internet, and growing more capable the moment you connect it. Your data does not leave the premises unless you decide it should.

Try any WatuFlex solution free for 30 days

WatuHRM, WatuSchool, WatuAccounts, WatuCRM, WatuKopesha, WatuFleet, WatuTime, WatuVisitor or WatuMEAL — the full edition, installed on WatuOS in your own office, with your own data. No payment and no card. Nothing is charged at the end: if you want to keep it, the licence is switched on and everything carries on; if not, it simply stops.

Already a WatuFlex client? Register with the e-mail address your organisation gave us at installation. That is how the website recognises you and opens the whole Repository — a different address only gets the free samples.

  1. Register free, and confirm your e-mail.
  2. Choose the applications you want to try.
  3. We contact you and set it up on WatuOS — on your own computer or a ready Watu Box. You do not install anything yourself.
  4. Use it for 30 days. Keep it, or let it end. Your call.

Three parts, one system

You do not need to understand Docker, Linux or servers to run WatuFlex. That is the entire point of building it this way.

New this month

What shipped in September 2026. Every line below is in a released build, not a plan.

ReleaseWhat changed
WatuOS HR Edition 2.6.1The client's own administrator now chooses the backup passphrase, so an off-site copy opens on any machine even if the box is lost. WatuOS updates are signed and delivered from Watu Cloud, and rolled back automatically if the desktop stops answering. Security updates install themselves.
WatuHRM 3.3Sample data for 39 kinds of employer, grouped by sector and searchable — banks and SACCOs, construction, mining, estates, transport, supermarkets, clinics, councils, security companies, NGOs, a church, a diocese, a mosque trust and a generic organisation.
WatuFleet 2.2, WatuKopesha and the Microfinance EditionWatuFleet 2.2 is for companies that run vehicles for a living — trucks, trailers, tankers, buses and large car fleets: fuel, trips, servicing, tyres, papers and what each vehicle really costs, with GPS trackers read through Traccar and every cost sent to WatuAccounts. WatuKopesha, core banking for microfinance and SACCOs, joins the family, with a WatuOS Microfinance Edition planned.
Accounts and a free trialTry any WatuFlex solution free for 30 days. watuflex.com now has accounts: a free one opens a sample from every Repository pack, and clients with an activated WatuOS box open all of it.
Watu Cloud 1.6 and 1.7Clients with several boxes each; roles for sales representatives, support engineers and finance; a billing report; compulsory password change and optional compulsory two-step sign-in; a built-in manual and FAQ for every role.
WatuCRM 1.3Connected to Watu Cloud: a won deal becomes an enrolment token from the company page, each client's boxes and licence dates show in the CRM, and licences about to end turn into renewal tasks and deals.
In testing: WatuOS Business Edition Thirteen applications on one box with WatuAccounts at the centre — WatuHRM, WatuCRM, WatuPOS, WatuStock, WatuProcure, WatuProjects, WatuMake, WatuService, WatuFleet, WatuTime, WatuNet and WatuVisitor. Each one works on its own; connected, each sends its invoices, bills and journals to the books, so nothing is typed twice. One click in WatuAccounts loads the same sample company into every connected application, and one click removes it. Not released yet. What is in it →

When your 30 days end

Nothing is charged automatically, and nothing is sold to you without a written quote. Before the end, choose one of three.

Keep itTell us, and we send a quote for the edition and the number of staff you have. Once it is agreed we switch the licence on from Watu Cloud — same machine, same data, no visit.
Need more timeAsk before the trial ends and we can extend it while you decide, for example until the next board or finance meeting.
Let it endDo nothing. The trial simply stops and you owe nothing. Export anything you entered first.

Upgrading never means starting again

This is the promise the whole platform is built around. Moving from the free edition to the commercial one is an activation, not a reinstallation. Same machine, same application, same data — features switch on.

1. BuyYou purchase the commercial edition of an application you are already using.
2. ConnectThe box reaches Watu Cloud on its next outbound check.
3. VerifyCloud confirms the licence and issues a signed entitlement to that box.
4. DoneFeatures are on. No visit, no migration, no export and import.

Because every WatuOS installation already carries every application in its edition, adding a whole new system to your organisation is a licence change rather than an installation visit. If a licence ends, the applications keep running and your data stays exactly where it is — what stops is the cloud service: updates, new installs and off-site backup.

The editions

Pick the edition that matches the work. Every edition is the same operating system underneath — they differ only in which applications are licensed to run. Each one can be tried free for 30 days; the images are downloaded by clients and by organisations on a trial.

Waiting for the Business or Microfinance Edition? Register free and tick WatuAccounts, WatuCRM or WatuKopesha — we tell you the day it is ready, and you can be among the first to try it.

What it costs

One licence per box covers the applications in your edition, signed updates, encrypted off-site backup and support. The price depends on the edition and the size of your organisation, so we quote in writing before you pay anything — and the 30-day trial is always free.

Your own computer, or a Watu Box

WatuOS needs one machine in your office, on your network. You can use one you already have, or take a Watu Box from us. Either way, we do the installation.

Your own computerA desktop or mini PC you already own, given over entirely to WatuOS — its disk is erased at installation. At least an i3-class processor, 8 GB RAM, a 240 GB SSD (never a spinning disk), wired network and a small UPS. Full hardware list →
A Watu BoxA small, quiet machine supplied by us with WatuOS already installed and tested before it reaches you. Plug it into power and your network, and it is ready.
Ask for a price

Either way the box works with no internet. Connect it when you can, for updates, SMS and off-site backup.
