Chen Build connects the head office with every site: material requests and approvals, stock at each site, tasks, daily site reports with photos, payroll with Rwanda PAYE and RSSB, and clear reports for the director. On a phone or a computer, even with weak internet.

Who it is for
The site asks, a manager approves, procurement buys, and the store or site confirms the delivery. Each person gets an email at their step.
The main store and each site: deliveries, transfers, use and stock counts, with an alert when a material runs low.
Give work to a person and follow it. Every day each site reports the work done, the workers on site, progress, problems and photos.
Budgets, purchases, client invoices and profit per project. Payroll with Rwanda PAYE, RSSB and CBHI, and payslips sent to workers by email.
A summary every Monday morning and a monthly report for each site, to print, save as PDF or open in Excel.
Ready-made roles you can change: what each person can see and do, for every site or only the sites they work on.
Each person gets the emails that concern them, at the address they were registered with: their tasks, requests, reports, announcements and account.
Your logo, colours and company name on every screen and email. It installs like an app and keeps working with weak internet.
Each company has its own database, backed up every night, and handled under Rwanda's data protection law.
Screens from the demo company, which you can open yourself.



Create your company in two minutes. 30 days free, nothing to pay.
Each person gets a welcome email with their address and username, and installs the app on their phone.

Yes. Every company starts with a 30-day free trial. You can also open the demo company and try each role with one tap.
Yes. It opens in any browser and installs on Android and iPhone like an app, with your company's name and icon. Work saved without signal is sent when the signal returns.
Everyone who signs in gets a username and password from your company admin. An email address is strongly recommended: it is where they get their welcome email and every notification. Casual workers in payroll do not sign in; add their email only to send them their payslip.
Only the roles you allow. For each part of the app, a role gets no access, can only look, can add and edit, or can manage, for every site or only its own sites.
On Microsoft Azure servers in Johannesburg, in a database for your company only, backed up every night. Chen Nexa follows Rwanda's data protection law.
Nothing is deleted. Your team can still see every record, but nobody can add or change anything until you renew.
