Specialist Service Contract
(including custom calculators)

The following (blue and red text) constitutes the wording for a legally binding contract between CalQlata and its clients for the provision of CalQlata's specialist services and the creation of custom calculators to client specifications.

After agreeing the price and associated workscope, the client must copy and paste the following Contract Text onto his/her/its headed notepaper, correct all text highlighted in red and add his/her signature. In the event the client is a company, the signature of a Director is required. CalQlata shall supply the client with a contract number that is to be incorporated into the title of the printed/signed document.

The client may modify the format of the contract text but not the wording.
The signed document is to be scanned and emailed to CalQlata before the workscope can commence.

Until a professional relationship between the client and CalQlata has engendered sufficient confidence, CalQlata advocates the following approach to its clients for the provision of CalQlata's specialist services:
i) Break-up the workscope into small, controllable 'packets'
ii) Ensure that each 'packet' generates a useable result or conclusion
iii) Create a contract from the document provided below for each 'packet' as required
