Please note: Mistral endeavours to make most facilities available from this website fully automated. For security reasons however, increasing the program installation allocation requires manual staff intervention to Mistral's records and also Server. Depending upon receipt of payment confirmation, international time differences and workload, this may take up to 24 hours. Please therefore be patient. Your request will be met as soon as is practicable.

mistral_document_icon.gif IMPORTANT NOTICE

Mistral's current Price List may in some cases show prices higher than those charged to long term licensees.

Mistral's price policy has always been and remains PRICES FIXED IN PERPETUITY - for annually renewable contracts such as Corporate Licences and Subscription Licences for example. Naturally this policy is made subject to inflation and which in Mistral's case is indexed to the UK Retail Price Index. For this reason, where new products have been introduced since a contract has commenced these may have necessarily been introduced at higher prices in order to meet increased development and ongoing maintenance costs.

Established licensees therefore gain the benefit of Mistral's programme of continuous product upgrading and updating development at ostensibly the same price as commencement of their contracts.

Existing Licensees are respectfully reminded that Mistral's licence credit terms are strictly 30 days (unless a separate agreement has been established). Failure to remit within agreed credit periods will result in annual contracts being automatically voided. New contracts will be subject to current prevailing rates. Date of payment also does not affect contract anniversary renewal dates and which remain fixed in perpetuity.

Existing Licensees should therefore always remit annual licence renewal fees against their digitally received invoices using:- Remit. And not start a new contract and which may be at increased prices.

Simple rules, easy to follow. Here for a simple reason. To help us plan and run our business efficiently and to save you, our valued clients and upon whom we depend, your money.

Please help us to help you by following these rules. Thanks.

Lifetime Licenced Programs and Databases.

Please be aware that Lifetime Licences apply to the program version designed to run under the computer Operating System version at the time of purchase. If the Operating System (Windows version) is subsequently upgraded and this necessitates a similarly upgraded Mistral program system then this upgrade will NOT be offered free of charge. Upgrades will however be offered to existing licensees with discounts from currently published list prices and these discounts may be substantial (from minimum 50% to maximum 80% depending upon version interval).
