Before contracting with you for service, your client will want to know exactly how much the project will cost them. Costings include consultancy charges and any expenses that will be incurred and recharged to the client.

There are many ways of developing budgets for your projects. You can create budgets in accounting and project management software, or manually using spreadsheet software such as Microsoft Excel.

A confidentiality, or non-disclosure, agreement demonstrates both the client’s and the consultant’s commitment to preserving the privacy of each other’s business interests.  The level of confidentiality that must be maintained depends on the unique nature a specific engagement.

A sample confidentiality agreement is available here.

A letter of engagement is a formal agreement between a client and consultant, and is also referred to as a contract. This agreement binds the consultant and client together for the length of the consulting engagement. It illustrates the intentions of the client and consultant to work together in a specified way for a definitive period of time in order to achieve particular goals. Ultimately, this document holds all of the information included in the initial proposal along with a signature block to illustrate agreement.

A sample letter of engagement, or contract, can be accessed here.
