attendance

For a cloud-based multi-tenant HR/payroll system receiving real-time attendance events from ZKTeco devices, think of it as a distributed system rather than an attendance feature. The difficult part is not receiving punches—it's guaranteeing that every punch is captured exactly once, correctly mapped to the right employee, office, timezone, shift, and payroll period.

This is tailored to appeal to real buyers (HR teams, product teams, trainers, researchers) and help convert them without relying on respondent recruitment. ([surveyflip.com][1])

help me something with. I'm about to make a big customer data application where millions of data with demographics will be there and other attributes. people can use our service to target customers to avoid high paying Google cpc and facebook ads. what's the name of this type of application so that I can look into some competitors apps ?

The general category name for applications like this would be:

Below is a comprehensive, battle-tested audit & test scenario checklist I would use if I were hired to audit a production-grade SaaS accounting platform before scale. This is written from the perspective of real-world accounting failures, regulatory audits, and customer disputes—not just happy-path QA.

1. Core User Roles

You’ll have three roles:

In an Accounting SaaS App based on laravel, I need to implement a full featured custom field functionality to be added to different table.

The attached images is from smart office. So they have a list, and clicking the list brings up the custom field designer with some props. And this can be added to the the Create edit screen.

Suggest me the best way to achieve this. I'm using laravel 12, blade, bootstrap, jQuery. Suggest me both from the architechture point of view and also from the UI as well.


You:

Suggest me between these two. Making them in 6-12 months, which will have a better possibility to get some paid clients quicker than the other ? I'm 20 year+ seasons backend dev and with the help of AI, i can build systems really fast. Accounting & HR/Payroll SaaS like smartoffice.ai Recruiting portal like Breezy HR

If you want to rebuild a clone of Akaunting—a full-featured, Laravel-based accounting system—you’re essentially planning a massive ERP-grade application. The public surface looks simple, but the hidden details are where most developers underestimate the work. Here’s what you realistically need to be concerned about.
