Back in 1992 Sentri Systems was born, and over the last 28 years we think we have seen just about everything relating to T & A problems. Problems with tardiness (Late comers and Early leavers), overtime queries, excess absenteeism to name a few. Your problem/request will have to be extremely "different" for us not to be able to come up with a solution.


No doubt, by now, you have heard all "THE STORIES".


With a combined experience in excess of 100 years we have the expertise to solve your issues.


You ARE at the right place!

Cloud Solutions

Why do you need a cloud solution?


After analysing many requests, over quite some time, the following questions/requests repeated themselves in one form or another:


I own a small retail outlet with 3 employees and need to know if my staff are at work and what time they opened my shop.

I want to monitor the time worked by my domestic worker/gardener.

and the most common

I need something simple.


This led to SimpleTime.

Then we get another group of employers/business owners with the following situations:


You own a construction company and your workers are onsite, a "normal" clocking system will not work for you.

You own a security company and your guards move from site to site, you need to know where they are and when.

You do a lot of traveling and need to know who is at work when you are anywhere in the world.

Your employees go directly to site from home and must only be paid from when they clock in onsite until they leave the site at the end of their shift.


The list is endless.


If you fall in to the above categories or your business has a similar operation then you need FaceTime.


As the name suggests SimpleTime is a simple, basic attendance system aimed at companies with a small staff compliment, where, even though all the days clockings are recorded, the calculation of the number of hours worked for the day is based on the first and last clocking for the day.


If you need to know the actual hours worked, your staff work night shifts, you want to monitor absenteeism or have complex shift settings please have a look at TurboTime.


Here's how SimpleTime works:

There are two options to record your employees' times:


Option one TT635 fingerprint reader, requires a wi-fi connection. This is a fixed unit and the recommended option for businesses, such as retail, where you want to monitor the time your business opened.


Option two is to use an "older" cell phone or tablet (minimum of android 6) and can be used by domestic workers etc. This option requires either data or a wi-fi connection.


Or use both if this suits your needs.

With both options you have automatically removed the chances of staff clocking for each other, "Buddy-Clocking".

Once your staff have started clocking you can log into the cloud and view your employees times.

The days are colour coded so you can see at a glance what is happening.

Completed Shift (Target Reached)

Missing In Clocking (Why?)

Missing Out Clocking (Why?)

Incomplete Shift (Target NOT Reached)

AWOL (No Clockings for the Day)

Request Pricing

If there is a valid reason for a missing clocking it can be added manually.



You are now ready to print your clocking report. This report is available in two variants:

PDF (uneditable). This format could be mailed to your employee.

Excel (editable). Use this to make any changes before submitting to payroll.


In the example below the Friday shows red indicating missing clockings (In this instance a Public Holiday). Saturday and Sunday show in beige because the employee is not required to work on these days, though he might.

FaceTime is aimed primarily at, but not limited to, companies whose staff members work away from home (i.e. They do not report to the companies premises in the mornings but go straight to "site").


This gives rise to the following questions:

What time did they say they arrived onsite compared to the time they actually arrived?

What time did they leave? What time did the customer say?


FaceTime has GPS co-ordinates of where the clocking took place, so your sales rep can no longer "clock-in" while he is still in bed at his hotel.


You can also monitor other times and GPS co-ordinates, such as, when did my TLB and driver arrive on site?

Request Pricing

Because the clockings are stored in the cloud it is possible to use a personal cell phone (e.g. field technician) or have a tablet to be used by a team (e.g. construction site).


The first image is mainly used for administrative functions. The photos with notes button allows for your staff to email photos of anything that is out of the ordinary (e.g. Running late Road Block and attach a photo of the traffic jam.).


The second is the main clocking screen with the facility to have special in clockings (e.g. meeting at child's school) and special out clockings (e.g. going to doctor). These reasons are recorded as an absentee reason.


Built in trip monitor:

The green van for the start of a trip, the red van for the end. Breadcrumbs of the trip with latitude and longitude are recorded.


The green cog shows the number of clockings waiting to be sent to the cloud, the red cog is used to access the admin screen.


Because the system works both online and offline, it can even be used underground, the clockings are stored in the devices' internal database and transfered as soon as there is an internet connection.

Request Pricing

Once your staff begin clocking you can generate your reports, of which there are two for T & A.

Use the trip monitor to "follow" selected employees.

And view the trips in Google Maps, Google Styled Maps or Google Earth.

TurboTime is one of the most powerful Time and Attendance packages available on the South African market. (With installations in neighbouring states and as far a field as Belgium).


TurboTime comes with the advantage of not carrying ANY annual license fees. Once you buy the software it is yours forever, but we don't leave you out there on your own. We have a team of highly experienced software support technicians to assist with any queries that may arise.

The most important setting in any T & A System is the shifts. If these settings do not conform to your company rules then the results will be wrong and your company could easily be losing millions in Overtime payments.


Whether you have a basic 07:00 to  17:00 shift with a one hour lunch break or you have a complex shift where your team work from 07:00 to 12:00 then go home and return to work at 19:00 and work through to 07:00 the next day (all in one shift). TurboTime can be set up accordingly.

Many clients are amazed how badly their existing system is being abused when they start with the shift settings.


Once you are happy with the shift setup (this may appear to be a daunting task, but don't worry we help you with these settings) we need to look at the working week and the rules that apply, e.g. Must your employees work on Saturdays?

Some of you are looking at the working week and saying "that can't work for me". Well we have thought of that eventuality for those of you whose employees don't have a pattern (this is very common in Restaurants and Filling Stations). Schedules allow for you to allocate shifts to employees on a daily basis.

Request Pricing

We even accommodate large companies (a real life example: over 2000 employees at more than 40 branches), This would be extremely time consuming for one person, so each branch manager captures his employees work rosters in the cloud, and once approved they are pulled into TurboTime (the branch manager can only see employees assigned to the relevant branch).


You now know what happens when your employees are at work, what happens when they are not? There are 200 absentee reasons (many user editable) for you to choose from. You can decide if the absentee reason is paid for in full, partially paid or not paid.


Colour code the Absentee Reasons so that they stand out in the Calendar (We recommend Red - Bad e.g. A.W.O.L, Orange- So So e.g. Sick, Green - Good e.g. Annual Leave.)

You can see at a glance any patterns. This employee is a potential problem. He has 7 A.W.O.L. Fridays in a Calendar year.

Once your clockings have been imported you can view the times, edit, where necessary, and handle any exceptions (Missing Clockings).

TurboTime currently has over 100 (yes 100) different reports. We think we have thought of everything, but we will design reports to suit your specific needs on request. All Reports can be printed or exported in PDF, Excel or as text documents. Email to predetermined managers automatically, if you so require.

As an optional extra TurboTime currently has over 70 payroll interfaces, this includes variants of South Africa's two most popular, VIP and Pastel. We even have interfaces for clients with their own in-house payroll systems. If your system is not currently on the list send us a sample import file and we will do the rest.

Because of the close ties with Time and Attendance, TurboTime have developed the Job Costing system, to help you monitor your employees productivity. e.g. Your employee is onsite for 8 hours but only works for 2, WHY? You can now make sure you are paying your staff for working and not just being at work. Visit for more information.

Our latest developments are the integration of TurboTime with the cloud. You can now see your employees schedules, clocking times and absenteeism from anywhere in the world giving you even more control over your business.

So you have decided on your software options, now you need to decide on the equipment you will use to record the information.


The following points must be taken into consideration:


1. How many staff do you have? (Spending R 100 000 on a wave scanner when you only have 5 employees is overkill. Conversely having one fingerprint reader for 500 employees will also not work.)


2. The Nature of your business. (We do not recommend the use of fingerprint readers in industries such as metalworking or chemicals. Rather consider Facial Recognition.)


3. The environment. (Is there a possibility that the readers may be exposed to water, as in the food preparation industry, then an IP65 reader will be required).


Our sales team will help you with the decisions and our technicians will recommend the optimum placing of the reader (No direct sunlight is an example of this.)
