Services
What we do for you and what it costs
Software development, consultancy and payroll expertise for payroll, HR and accountancy. Six services with fixed rates from € 75 to € 125 per hour, depending on who works on your project, and a fixed day rate for training. All rates are exclusive of VAT.
Software development for payroll, HR and accountancy
Custom software that extends existing packages instead of replacing them. We build what is missing: an integration, a check, a tool that takes over the monthly manual work. Larger projects are done with a permanent network of freelance developers, all at least mid-level, at the same hourly rate per developer.
API integrations (REST and SOAP) between payroll, HR and accountancy packages
Web applications and desktop tools for recurring calculations and reports
Document conversion and data migration between packages
Automated testing, CI/CD and cloud deployment (Azure, Google Cloud) included as standard
Rate
€ 75 /hour excl. VAT
For example
Monthly export from Nmbrs to a pension provider
Web app that converts Loket documents to Nmbrs
Report that is in Visionplanner every morning
Rate
€ 110 /hour excl. VAT
For example
Half a day: automation scan of your payroll process
Second opinion on a quote from a software vendor
Sparring partner for your own IT person or developer
Consultancy on software and automation
Independent technical advice for firms that want to automate but do not know where to start. No sales pitch for a single package, but a concrete plan.
Selection and setup of integrations between your current packages
Architecture and API review of existing custom solutions
Mapping automation opportunities: where is the most time lost and what does it yield?
AI tooling in the development and administration process, applied practically and safely
Payroll & HR expertise in your software project
Software for payroll administration has to be built by people who know what a daily wage is. Alongside our own payroll background we bring payroll and HR experts with more than ten years of experience into your project: for the rules, the checks and the acceptance.
Calculations according to UWV and Tax Administration methodology (WAZO, daily wage, transition payment)
Pension filings and changes prepared and checked automatically
Payroll checks on 100+ points before the pay run instead of corrections afterwards
Collective agreement and sector rules translated into repeatable, tested logic
Experts join the project team or review at agreed moments, you choose the scope
Rate
€ 125 /hour excl. VAT
For example
Checking tool that ticks off every pay run
Pension filing for taxi and transport companies
Daily wage calculation in seconds instead of hours
Rate
€ 950 /day excl. VAT
For example
Nmbrs SOAP API: from zero to a working export in one day
Setting up a Silverfin integration for your own product team
Half-day follow-up session at the first release
Training: build an API integration in one day
For software companies and firms with their own developers who want to build an integration with a package we have already worked with. In one day we set up authentication, the data structure and the first working calls together: the knowledge that once cost us a week of research. By the end of the day you have everything you need to finish your project.
Available for Nmbrs, Loket.nl, Silverfin, Visionplanner and FiscaalGemak
Hands-on: your developers build it themselves, we guide and explain the pitfalls
Includes sample code, documentation of the quirks of each API and a checklist for production
On site or remote, for groups of up to 10 participants
General development projects: web, mobile and desktop
Not every project is about payroll. For websites, web applications, mobile apps and desktop software we put together a small team: LK Software as point of contact and architect, complemented by mid-level developers from our network.
Web applications and websites (React, TypeScript, Node.js)
Mobile and desktop applications (C# / .NET)
Backend, databases and cloud hosting (PostgreSQL, Azure, Google Cloud)
Same way of working as with custom software: short iterations, interim demos, tested before going live
Rate
€ 75 /hour excl. VAT
For example
Client portal for a bookkeeping firm
Internal planning tool as a web app
Company website with a secured download area
Rate
€ 75 /hour excl. VAT
For example
Monthly maintenance package for a checking tool
Annual update of pension integrations
10-hour bundle for small questions and updates
Maintenance & support for software and integrations
Software that has been built has to keep running. We maintain services and applications, keep integrations up to date with API changes and are available when something goes wrong.
Monitoring, backups and updates of services and applications
Adjustments for new API versions of Nmbrs, Loket, Silverfin and others
Fixed response time for incidents: within one working day
Prepaid bundle of 10 or 20 hours, or a fixed monthly fee based on your environment
