The “price” element will not be hold fixed or constant along the year.
In general, following variables will have impact on the price:-
1. Manufacturer price change – manufacturer price change from time to time. Some every year will revise the new price rate, some will revise after couple of time. Add-in or bundled with new functionality or module usually will raise the price up as well. The only way to overcome the impact related to this is procure multiple years in advance and pay in one go, so the company can lock the fixed rate when over the long term enjoy the saving.
2. Currency exchange rate – for oversea origin product subject to currency exchange rate changes up and down. If the product price is hold the same, change in currency exchange will have the impact on the rate.
3. Taxation – for local country impose value added tax (such as VAT, Government Sales and Services Tax) and import duty etc or change from the rate will have the impact on the price as well.
4. Inflation – for most of the country unless in deflation, the rest will under going inflation at the various speed, the same amount of local currency compare over time will noted on become less in value due to inflation, and it will impact on the price as well.
For customer concern on and forecast for the long term need for the product, one of the best way to reduce the impact of price change is to book the multiple year order and pay in one go to enjoy the saving.
