Frequently Asked Questions

  • ThunderBolt allows your business to run multiple business applications on a single powerful platform. This means that your data throughout all departments and applications remains in one central database.

  • Short answer: it is the best of both worlds. It is better to think of ThunderBolt as inbetween the two extremes of SaaS and Custom Software. With SaaS you are one of many people using the software which means that you do not own the IP or data. With Custom Software you have to start from scratch and this means high cost. With ThunderBolt, you own the IP and data plus you can customise modules and applications that have already been developed and tested.

  • Yes. Our team will work with you to ensure your ThunderBolt software is connected to all the third party apps you are currently using.

  • The data belongs to you. You have full control on where the data is hosted, who can access it and what methods can be used to analyse it.

  • There are many reasons ThunderBolt is better however you will find the biggest reason for choosing us is that the code and data will ultimately belong to you and your company . Also, you are not constrained by monthly license fees nor by the fact that your sensitive data is being held along with hundreds of other companies’ data. Finally the entire platform will be branded and customised for your company which in essence means that it will become one of your company’s most valuable assets.

  • Yes; and our marketing team will ensure you are kept up todate with the latest news and releases. At any time you can "bolt" on more applications with no downtime to your current software.

  • ThunderBolt belongs to you and of course if you want to stop using it, you can. All the data is still yours, residing on your server.

  • Yes; as part of the customisation process, our team will work with your company to ensure that all third party apps are connected.

  • This does depend on the level of customisation. However, we find that your company will be using the platform within 2-4 weeks of the design signoff period.

  • If you are happy with our proposal, then you will be assigned an account manager who will get you the first available development slot. The first step will be to begin to document the system in the form of functional document. This document once approved will ultimately act as a guide for our developers throughout the entire development cycle. Also, the completed system will be tested against the specs laid out in this document.

  • We are confident we can deliver a solution that will fulfil all your requirements thus ensuring that Tentacle and your company will enjoy working together for many years to come.

    To that end we will only ask for payment at “Testing Signoff” i.e. after complete development and when you have had a chance to use AND APPROVE the system. At any stage before this, you are free to walk away at no cost to yourselves.

  • Our goal is to keep you in the loop whilst we develop your system. To achieve this Tentacle Solutions will provide you with frequent updates sent by your account manager.

  • As your staff’s day to day operations grow and diversify so should your system. Tentacle Solutions will be on hand to offer solutions to your needs no matter how small or large the job may be.

  • Absolutely not! The advantage to selecting ThunderBolt is that you will be always be in control of your system’s code and I.P. This means you will be able to easily move your system to another provider / development company.

  • All our products come with a 12 month warranty. We also have a multi-tiered support team that will be ready to help you at any time.
