Who is Zentra for?
HR and payroll for South African employers: people, leave, time, SARS-compliant payroll, recruitment, performance, training, employee relations and an employee portal.
What problem does Zentra solve?
The usual starting point: Payroll runs on a spreadsheet that one person understands. With Zentra: payroll calculated to SARS tables with every statutory return produced, and employees who serve themselves on the portal or on WhatsApp.
Is our data kept separate from other organisations?
Yes. Each organisation's data is separated by row-level security in PostgreSQL, enforced by the database itself, and every sign-in, change and approval is written to an audit trail.
Do we have to use the Zen assistant?
No. Zen is switched off until an administrator in your organisation turns it on. When it is on, it sees only what the signed-in user is allowed to see, and its questions and actions are audited.
Can Zentra connect to our other systems?
Yes. Every Alexon platform has documented APIs and webhooks, and connections set up once in the integrations hub can be reused across products. We confirm the specific connectors you need during discovery.
Can we get our data out?
Yes. Your data can be exported in open formats at any time, and everything the interface can do is also available through documented APIs.
How quickly can we get started?
Discovery takes one to two weeks. You then work in an environment on your own data while we configure, integrate and prove the platform, typically by weeks four to eight depending on scope and data migration.
