Amazon: run it yourself or hire an agency? The honest split

What DIY can genuinely achieve on Amazon India

More than the agency industry admits. A founder with ten focused hours a week can run a competent Amazon operation to roughly ₹5–10 lakh monthly revenue: listings built properly (keyword-researched titles, benefit-led bullets, A+ content from your existing creative), reviews seeded through Vine and your direct-channel review engine, basic Sponsored Products on your own brand terms plus obvious category terms, weekly negative-keyword hygiene, and Buy Box health watched through pricing parity (the pack-architecture rules). Amazon publishes most of its own rulebook; the early game is execution, not secrets. If your total marketplace revenue is under a few lakh a month, an agency retainer typically eats the entire incremental profit it generates.

Where DIY hits its ceiling

Three walls appear in a predictable order. The ads wall: past basic Sponsored Products, the stack (Sponsored Brands, Display, tighter match-type architectures, dayparting, placement modifiers) becomes a real practice; ACOS creeps while the founder's attention is elsewhere. The catalogue wall: more SKUs multiply everything — keyword maps, inventory forecasting, listing suppressions, flat-file surgeries, account-health firefighting. The events wall: Prime Day and festive events reward preparation depth (deal planning, inventory positioning, budget choreography) that part-time attention cannot supply — the same lesson as the festive playbook, on a shelf you do not control. When weekly Amazon work crosses ~15 founder-hours or ad spend crosses ₹2–3 lakh a month, the DIY maths flips.

On Amazon, the first lakh of monthly sales is a checklist. The tenth is a discipline. Know which one you are paying for.

What a good Amazon agency actually adds (and what it cannot)

Worth paying for: ads architecture run daily by people who see fifty accounts (pattern exposure you cannot buy alone), event preparation as a rehearsed routine, catalogue and account-health operations (the unglamorous flat-file and case-log work), and honest incrementality judgement — knowing when brand-term ads are defence versus theatre. What no agency can add: demand that does not exist. Amazon converts and captures demand; it manufactures very little. If the brand has no branded-search pool and no differentiation, an agency optimises your commodity position more efficiently — the ceiling stays exactly where it was, per the commodity trap. The agencies worth hiring say this in the first call.

Costs and deal structures in India

Typical 2026 ranges: project work (listing overhauls, A+ builds, account setup) ₹25,000–1 lakh one-time; monthly management ₹25,000–75,000 for boutique operators, ₹75,000–2 lakh for full-service marketplace agencies; percentage models at 3–8 percent of marketplace revenue or 10–15 percent of ad spend, usually with minimums. Structures to prefer: fees tied to contribution-margin outcomes over revenue vanity, quarterly review clauses, and full account ownership in YOUR seller central (never theirs — walking away must stay cheap). Structure to avoid: long lock-ins sold on a Prime Day promise.

The decision framework, condensed

• Under ₹3–5 lakh monthly Amazon revenue: DIY with a one-time professional setup (listings + ads skeleton). Spend the retainer money on creative and reviews instead.
• ₹5–15 lakh monthly, or ads spend past ₹2–3 lakh: the flip zone — hire for the ads practice and event depth, keep strategy and pricing in-house.
• ₹15 lakh+ monthly or multi-marketplace (Flipkart, quick commerce): professional management pays for itself in event execution and error avoidance alone; your job becomes demand creation off-platform — the flywheel that makes every Amazon rupee cheaper.
• Any level: if the account is your only channel, fix that before hiring anyone — channel concentration is the risk no agency manages away.
