When you need durability _ Key card envelopes can be made in Tyvek as well as paper. Tyvek is tear_proof and water_resistant, and is an excellent choice when you need the envelope to be durable. If the card is something a person will hold onto for a long time, Tyvek is a better choice than paper. Key cards may only be used for a few days, but ID cards, ATM cards, and other cards that are distributed in envelopes might do better in Tyvek. A more durable envelope means the instructions for use will not fade or be lost when a paper envelope tears.
I never have to reinvent the wheel. And as a professional accountant, you can imagine how many different "wheels" I use every day! Profit & Loss statements, Balance Sheets, Cash Flow Forecasts, Time Sheets, Break_Even Analyses, Margin Calculations, Business Plans, etc, etc. When using your own prior work as a financial template, you get another benefit _ you are so familiar with the template that it takes you no time to figure out how to use it. And each time you refine it just a little bit more. So pretty soon your templates run like a Swiss watch! All the bugs have been worked out, you have tested it with many different clients and many different business scenarios and you know you have something you can depend on. Financial Templates as Tools _ For someone who is not a finance professional, financial templates serve a slightly different purpose. They still save time, of course, but they also provide a tool that person would have to pay someone else to develop.
