Should I hire an agency or manage marketplace ops in-house?
The short answer
In-house makes sense once marketplace revenue is significant enough to justify a dedicated hire (or founder time) who lives inside Seller Central/Flipkart Seller Hub daily, agencies are faster to start with but you're paying for expertise you can't fully audit until you understand the mechanics yourself. A reasonable middle path: run PPC and catalog hygiene in-house for your first 6-12 months to actually learn what good looks like, then decide if an agency's scale (managing spend across many brands, better rate access to reps) is worth the fee once you're ready to scale spend meaningfully. Whichever you choose, keep read access to raw performance data, never let ad spend decisions happen in a black box you can't independently verify.
