Question 1

How do agencies structure billing?

Accepted Answer

Agencies typically bill per project phase, on retainer, or as a fixed project fee. Milestone billing is the most common approach for large projects.

Question 2

What about scope creep?

Accepted Answer

Document the original scope clearly. Any work beyond scope should be tracked as a change request and invoiced separately with client approval.

Question 3

Should agencies require upfront payment?

Accepted Answer

Yes — requiring 25-50% upfront is standard practice. It covers initial costs and demonstrates client commitment.
