[xx] Tips for Writing an Effective Bid:
With thousands of freelancers competing for jobs and perhaps a
hundred or more bidding on the same job, how do you make your bid stand out
from the rest? The fact is each employer is as altered as each freelancer, so
there truly isn’t a “magic formula” that tasks for every bid. There are,
however some significant stages you can take to growth of the chances that a
prospective employer will consider your bid extremely. Here are ten simple tips
for writing an effective bid:
222. Reading the project description
carefully is required. After all, if the employer doesn’t feel you understand
the project, you’re not likely to win the bidding. Besides, many employers will
ask for specific details that you need to be aware of. In fact, employers often
include a phrase that must be included in your bid in order to have it
considered. The bottom line is, you should always take the time to go through
the description thoroughly.
223. If you have questions, use the Project Clarification
Board. Winning a project without knowing exactly what you’re getting into isn’t
a good situation for you or the service buyer.
224. Keeping your bid clear, concise and to
the point. Remember that the employer may have dozens or even hundreds of bids
to consider. It’s very likely that every word of every bid isn’t going to be
read. Bids with unnecessarily long descriptions may be skipped over completely.
Don’t invite the employer to ignore your bid by making it too wordy.
225. Stating your terms clearly and specially.
Using the project description as a guide, be as precise as possible in stating
exactly what you’ll provide, how much it will cost, and how long it will take
to deliver. Being vague about your terms implies a lack of confidence. If
you’re not confident in yourself, the employer won’t be, either. As we’ve
already mentioned, use the Project Clarification Board to ask the employer
questions if you need more details.
226. If the employer contacts you through a
private message, be sure to responding promptly. Most employers award projects
within the first 24 hours of posting, so ensure you keep yourself available for
contacts.
227. It’s always a good idea of uploading
samples with your private message or providing links to online examples. Be
sure, however, that your examples are appropriate for the job and represent
your best tasks. Quality, not quantity is usually the rule of thumb when
submitting samples.
228. A word of precaution: Unless you’re
prepared to give your work away, any samples you provide should bear a
watermark or other means of identification or at the very least your name and a
statement of copyright.
