Task work has one number: what you are paid for doing it. Supply work often has two, and members who blur them end up out of pocket without understanding why.
The two components
Your fee — payment for finding, buying, transporting and delivering. This is your earnings.
The cost of the goods — money spent on the merchant's behalf, which returns to you unchanged. This is not income, and treating it as such makes a job look profitable when it was not.
A supply job where you spent 4,000 and were paid 4,500 earned you 500. Recording it as 4,500 will convince you the work pays far better than it does.
Who buys the goods
This varies and must be agreed before you start. The merchant may fund the purchase directly, advance you the money, or expect you to buy and be reimbursed. Only the last one puts your own money at risk, and it is the one to be most careful about.
For a first job with a new merchant, being cautious about fronting cash is reasonable, not rude.
How the platform side works
Work posted on Knomart is funded before it appears, so the money exists before you accept. Once the merchant confirms delivery, payment is released; if they say nothing, it auto-releases after seven days. You receive the full posted amount, because the 5% platform cut is paid by the merchant on top rather than deducted from you.
Getting it out
Task and supply earnings land in your wallet and become withdrawable once the balance reaches $40. Pool and deposit balances have no floor at all. Knowing which wallet a payment lands in tells you when you can actually take it out.
Keep receipts separate
Every purchase receipted, handed over, and recorded apart from your fee. That is what lets you and the merchant agree the reimbursement without either of you reconstructing it from memory.
