Field note
Write the source list before you spend on the first campaign
The cheapest time to name booths, chats, creators, and listings is the week before money moves — not the Friday after the first report looks odd.
Most launch teams we meet in Johor already have a media plan. Few have a source list. The difference is that a media plan names what you intend to buy. A source list names every door a person might actually use.
Start with the listing in both languages you will publish. Add each paid campaign under the name that will appear on the invoice. Add each creator, including the ones who have only been “maybe.” Add staff and family as a named line, not as a joke. Add any physical presence — a campus table, a pasar booth, a sticker run.
Then ask, for each line, how a first open would carry that name. If the answer is “it should just show up,” it will not. That line needs a parameter, a unique store link, a short code, or an honest decision to accept it as unlabelled.
Doing this before spend is unglamorous. It also prevents the particular Friday conversation where a founder stares at a pie chart and asks why half of it is grey. Grey is not a mystery. Grey is a door nobody named.
Bring the list to the people who will be awake on launch morning. If they cannot find their own work on it, the list is still a media document. Keep writing until the booth, the chat, and the listing have somewhere to sit.
