Every founder we speak to opens the conversation the same way — "what's your fee?" — and every founder is surprised when the answer is "it depends on which model we run." There are four mainstream commission models used by Indian marketing agencies in 2026, and the difference between them isn't a few percent. It's whether you're paying for effort or for outcomes.
This piece breaks down all four — flat retainer, percentage of ad spend, revenue share, and pay-per-result — with the real INR ranges you'll see in the market, who each model favours, and what to negotiate before you sign anything.
We run a performance-based marketing agency ourselves, so we have a stake in this. We'll be transparent about which model we use and why. But the goal here is to give you enough clarity to walk into a contract conversation with any agency in India and know what you're being asked to pay for.
The commission model is the most important contract clause you'll sign with an agency. It decides whether the agency gets paid for showing up or for moving your numbers.
Model 1 — the flat retainer
The flat retainer is the oldest model in agency pricing. You pay a fixed monthly fee — usually invoiced at the start of the month — and the agency commits to a defined scope of work. Common scopes are "manage paid ads on Meta and Google," "publish 12 blog posts," or "produce 30 social posts and 4 reels."
Typical INR range
Rs. 50,000 to Rs. 5,00,000 per month for full-service paid acquisition. Rs. 25,000 to Rs. 1,50,000 per month for content-only or social-only retainers. Boutique strategy retainers from senior practitioners can run Rs. 2-8 lakh/month.
Who it favours
The agency. Revenue is predictable, the agency can plan headcount around it, and the fee is uncoupled from performance. This isn't dishonest — it's just structurally tilted toward the agency's stability. The client carries 100% of the performance risk.
When it makes sense
Brand-building, content production, SEO, community management, and any work where you can't draw a clean line from "this thing the agency did" to "this revenue event in our books." If you can't measure it, paying on results is impossible to structure fairly.
Model 2 — percentage of ad spend
The most common commission structure for paid acquisition in India. The agency charges a percentage of monthly ad spend as their management fee. If you spend Rs. 3,00,000/month on Meta and Google ads at 12%, the agency invoices Rs. 36,000/month for management.
Typical INR range
10-20% of monthly ad spend, with the percentage scaling inversely with budget — small accounts (under Rs. 1 lakh/month) often see 15-20% or a flat minimum, while accounts above Rs. 10 lakh/month often negotiate down to 7-10%. Below Rs. 1 lakh/month spend, most agencies will quote a flat minimum (Rs. 25,000-40,000/month) instead of a percentage because their cost to service the account doesn't drop linearly.
Who it favours
This model is roughly neutral — agency income scales with budget, which is loosely correlated with results. But the alignment is weak. An agency on percentage-of-spend earns more when you spend more, regardless of whether the spend was efficient. They have no direct incentive to lower your CAC or improve your ROAS, only to keep the account spending.
When it makes sense
Established accounts with mature campaigns, where the agency's job is steady-state optimisation rather than aggressive growth. Also reasonable for early-stage accounts where there isn't enough conversion data yet to structure a true performance deal.
Model 3 — revenue share
The agency charges a percentage of revenue generated above an agreed baseline. Example structure — "we charge 12% of monthly revenue above Rs. 5,00,000." If revenue lands at Rs. 8,00,000, the agency earns 12% of Rs. 3,00,000 = Rs. 36,000.
Typical INR range
8-15% of revenue above a baseline for ecommerce and D2C accounts. The baseline is usually negotiated as the average of the trailing 3-6 months of revenue before the agency engagement, so the agency only earns on growth they can plausibly claim credit for.
Who it favours
Both parties, when set up well. The client pays nothing if revenue stays flat. The agency earns proportionally to the growth they drive. The risk is real for both sides — which is exactly why incentives align.
When it makes sense
Ecommerce, D2C, app businesses with in-app purchases, and anywhere you have clean conversion tracking and a stable revenue baseline. Doesn't work for businesses with very long sales cycles (where the agency's contribution to a revenue event months later is hard to attribute) or for very seasonal businesses (where the baseline calculation gets gamed by both sides).
Revenue share works because the agency loses money when you don't grow. That is what makes the model self-policing.
Model 4 — pay-per-result
The agency charges per qualified outcome — per lead, per booking, per purchase, per app install — at a rate agreed before work begins. The client funds ad spend separately. The agency's management fee is replaced entirely by the success fee.
Typical INR range
Highly vertical-specific. Rs. 200-500 per qualified B2C lead in high-volume verticals (insurance, edtech). Rs. 800-2,500 per qualified lead in considered-purchase verticals (real estate, healthcare, B2B services). Rs. 12-30 per app install in price-conscious app verticals, Rs. 40-90 per install in high-LTV app verticals (fintech, B2B SaaS apps). Rs. 150-400 per ecommerce purchase as a flat success fee.
Who it favours
The client — assuming the lead/install definition is tight. The agency carries all execution risk and only earns when results land. The risk for the client is that "qualified lead" can be defined loosely, in which case the agency optimises for technically-qualified-but-low-quality submissions.
When it makes sense
High-volume B2C lead generation, app installs, and any vertical with a clean conversion event that can be defined tightly enough to avoid gaming. Less common for ecommerce because it shifts cash-flow timing in awkward ways for the agency.
The four models — head to head
| Model | Typical INR Range | Risk Bearer | Best For |
|---|---|---|---|
| Flat Retainer | Rs. 50K–Rs. 5L/month | Client (100%) | Brand, content, SEO |
| % of Ad Spend | 10–20% of spend | Client (mostly) | Mature paid accounts |
| Revenue Share | 8–15% above baseline | Both parties | Ecom, D2C, in-app purchases |
| Pay-Per-Result | Rs. 200–2,500/lead | Agency (mostly) | B2C leads, app installs |
| Hybrid | Reduced base + commission | Shared | Mid-size accounts (Rs. 5L+ spend) |
The hybrid model — what most real engagements look like
In practice, most performance agencies in India above a certain account size run on a hybrid. A reduced base retainer (Rs. 25,000-50,000/month) covers the baseline cost of account management, reporting, creative production, and meeting time. A performance commission on top — usually a percentage of revenue above baseline or a per-result fee — captures the upside.
The hybrid exists because pure pay-per-result deals create cash-flow problems for the agency (they're funding work for 30-45 days before the first invoice can land), while pure retainers don't align incentives. The hybrid splits the difference — the agency has predictable income for overhead, and the client has performance accountability on the variable component.
If you're spending Rs. 5 lakh+/month on paid acquisition, the hybrid is almost certainly what any serious agency will quote you. If they quote you a pure retainer at that account size, ask why.
Red flags — when an agency's commission structure is off
- They won't share their commission structure in writing before a sales call.If the model is fair, they should be willing to share the framework upfront. Hiding the rate behind "we'll discuss in the call" usually means the rate is high enough to need a sales pitch to defend.
- The commission rate doesn't scale with account size.An agency charging 15% of ad spend on a Rs. 10 lakh/month account is overcharging — that's Rs. 1.5 lakh/month for management which doesn't take 10x the work of a Rs. 1 lakh/month account. Rates should bend.
- Performance commissions with no defined attribution."We'll take 12% of revenue we generate" is meaningless without a written attribution methodology. Last-click? First-click? Data-driven? The same campaign can show three completely different revenue numbers depending on which model is used.
- Pay-per-lead deals without a tight lead definition."Qualified lead" needs to be a single, falsifiable definition — "person who confirmed budget on a 15-minute call," not "person who submitted an email." Loose definitions mean the agency optimises for submissions, not real prospects.
- Long minimum commitments tied to commission models.If an agency is confident in their commission model, they should be willing to start with a 3-month initial term. A 12-month minimum on a commission model is the agency hedging against their own performance — they want to lock you in case they don't hit the target.
What to negotiate before signing
Five clauses to clarify in writing before any commission-based engagement:
- Attribution methodology — exactly which clicks, conversions, or revenue events count toward the commission, and which platform's data is the source of truth (GA4, Meta, Shopify, your CRM)
- Baseline calculation — for revenue-share deals, how the baseline is calculated, how often it's revisited, and what happens during seasonal swings
- Lead/install/purchase definition — for pay-per-result deals, the exact qualifying criteria and how disputes are resolved
- Direct ad account access — your ownership of the Meta Business Manager and Google Ads accounts, with the agency added as a user. Never the reverse.
- Termination terms — initial term length, notice period, and what happens to in-flight campaigns when the engagement ends
Frequently asked questions
In closing
The right marketing agency commission model isn't universal — it's a function of what you're trying to grow, how cleanly you can measure it, and how much risk you want the agency to share. Brand and SEO will always make sense as flat fees. Paid acquisition and lead generation almost always make more sense on commission or hybrid terms.
If you're spending more than Rs. 2 lakh/month on paid acquisition with an agency on a flat retainer, the model itself is probably costing you more than the fee suggests. The same money split as a hybrid — small base plus revenue share — usually gets you a more attentive agency for the same total spend, because the variable component pulls them toward your numbers.
At GUROB, we run hybrid commercial terms for app marketing, B2C lead generation, and ecommerce growth. The base covers our overhead, the variable rewards the outcome.
