Frequently asked questions
Custom web application questions
Clear answers to common planning and selection questions.
How long does a custom web application take?
It depends on the workflow. Zerolink plans a first working release around the most important process, then adds features in short phases so your team starts using it early.
Will it work on mobile phones?
Yes. Applications are built responsive, so staff and customers can use them in any phone, tablet or desktop browser.
Can it connect to our existing software?
Usually yes. Payment gateways, SMS and WhatsApp messaging, email, accounting and other systems with an API can be integrated after the interfaces are confirmed.
Who hosts and maintains the application?
Zerolink can host it on secure cloud infrastructure with backups and monitoring, and provide ongoing maintenance — or hand it over to your own team with documentation.
Have a business workflow that existing software cannot fit?
Bring the users, current process, pain points and desired outcome to a structured discovery call.
