Operating Staff

In your team, you’ll need a variety of assistants, specialists, technicians and managers. This is to cover the running and operations of the payroll itself.

Legal Compliance

Different countries will require particular legal prerequisites when you start your business. Let’s use the UK as an example here.

PAYE (pay as you earn) allows HMRC to collect income tax and National Insurance from employees. For everyone, from your own staff to your clients, PAYE is needed to get the ball rolling. Registering for VAT, abiding by MTD (Making Tax Digital) is also a necessity for all UK payroll.

If you’re setting up in the UK, you have to know the ins-and-outs of HMRC and GDPR. Both of these bind your business to data protection and documentation processing. Such as processing employees’ P45s. Thankfully, has great resources.


We'll use Invatechs’ own software development as a model.

Step 1: Find Your Angle

Step 2: Determine Your Business Structure

You’ll need to decide where you’ll be running your business from. Whether it is predominantly remote or if you need an office space. You’ll need to decide on your business type. Whether you’re a limited liability company or umbrella company.

Step 3: Software Construction & Team Processing

Who is building the products you’re selling? You might have recruited or collaborated to build an in-house team. Alternatively, you might look for an external company to build the software that you’re selling. Whatever decision you make, your processing team and/or vendor are pivotal to your longevity.

Making sure your products fit the requirements for yourself and your clients. Tax calculations. Everything you expect your payroll product to do.

Prototyping and testing are crucial. You’re moving vast amounts of companies and employees’ wages and resources. The testing phase has to be rigorous and thorough. You’ll need people behind you with years of experience. Whether it’s coming from your team or the help of Invatechs. Product testing and prototyping is essential for safety.

Hopefully, you can see from these steps you need a confident team and vendor behind you. A vision isn’t enough. It’s a big project. So, let’s tackle some hurdles you might face.


Staffing Models & Distribution

Ensure your payroll configurations can cater to different staffing models. You might sell to clients with staff that employ freelancers, part-timers and full-timers. The system needs to work for clients overseeing various branches, divisions and locations. In the software development stage, ensure your system is built with flexible and dynamic configurations that can withstand changes and challenges.

Bespoke Payroll Development vs Standard Products

Some businesses will need bespoke suits for their operations. If you sell a standard product – even a very good one – it might not be adaptable for certain markets. This is another thing to determine early in your company’s scope. Bespoke payrolls suits generate a huge amount of capital in revenue, particularly if you sell to a big company. Check out Invatechs’ own bespoke payroll suits for more information.

Legal Knowledge

If your start-up team is small, it can be difficult to form a legal infrastructure for your business. Depending on a revolving door of outsourced legal advice may not be consistent down the line. For example, UK HMRC regulations differ to IRS regulations in the USA. It’s best to get all that legal advice in one place. That’s why all of Invatechs software and solutions are built with legal compliance. Bespoke to different locations and staffing models.


Above all, accuracy and data will be the driving force of your software’s success. This is why your technology and clocking in-and-out systems need to be efficient. It’s important your clients’ employees are confident using your system. Here, the cloud can save the day again. All timestamps, audits and reports can be ledgered in the same place. This means there’s transparency across the supply chain.


Costs will vary depending on your business structure and scale. Large scale, global companies will need a bigger capital requirement. A starting region of between 100k-150k. From training to licensing fees. Office renting and insurance. Navigating your start-up cost is a massive undertaking.

Of course, the scalability of your software and devices can be a money-saver and maker. For example, with our Invatechs payroll suite, managers can process x3 more customers with the power of automation. Like your team and vendor, your software isn't something you can afford to do on the cheap. They’ll be a driving force of your growth and revenue.
