Time zone differences "TZ", and a time delay of communications with our TZ, your TZ, and the countries TZ of which you are requesting.
We have our own work load and clients that are ahead of you. Our vendors also have their own work loads which are ahead of us. We all need to wait our turn.
Delay factors such as holidays in your country, our country and countries in which you are requesting advertising.
Our media providers having sick days, business trips, work loads, thier own pace and technical glitches on anyone's end which can cause delay.
Some countries you may be targeting may not have the information ready in English. Therefore EXTRA time to translate the content is needed before we can send you the proposal.
When considering international media buying and planning, expect to have the processes go 3 - 5 times SLOWER compared to planning you may be accustomed to doing it within your own country (where you are all on the same time zone and speak the same language etc.) . Extra time is needed in general to work out the “extra kinks” as needed.
Buying from a local media owner in your country is not the same as buying from an agency internationally as the information gathering is far more tedious. Depending on what you ask for and where, it may require more work.
In order to do an RFP PROPERLY, enough time must be allocated to us to think, plan, communicate, prepare, sort, translate if needed and make a proposal to you which is suitable. Quality work takes time. There are few shortcuts.
Speaking of short--giving short and tight deadlines only makes us offer you less options, or less than ideal options for you, and hence the client gets sold short in actuality.
MISSING INFORMATION WILL CAUSE A DELAY IN INITIATING YOUR REQUEST. If you are in a hurry, be comprehensive.
