Gartner forecasts India's public cloud spending to grow 28.1% in 2026, and IT services spending to grow 11.1%. Revenue from your top 20 accounts: flat. So the market is not the problem.
India public cloud, 2026
India IT services, 2026
Your top 20 accounts: flat. Gartner can tell you the market grew. It cannot tell you where one bank is putting its extra crores.
Sources: Gartner, India public cloud forecast, June 2026; Gartner, India IT spending forecast, November 2025. Both are forecasts.
Two lists for one account
The fastest way to see why a growing customer is not growing with you is to put two lists side by side. I took one BFSI account and did exactly that.
Testing
L2 support
Staff augmentation
Application development on T&M
AI pilots
Data platform
Cloud migration
Managed security
Overlap: one of four. Same customer, bigger budget, almost nothing on it that the company could bill against.
Same customer. Bigger budget. Almost nothing on it you can bill against
The second list came from the KAM, not a report
Where an account's budget is moving is account knowledge, and it sits with the people closest to the account. I did not build the second list from a Gartner report. I asked the account's Key Account Manager.
He knew two of the four. The other two he had to go and find out. That gap is itself a finding: the person who owns the relationship did not fully know where the customer's money was going next.
Then do it for all 20
One account is an anecdote; twenty accounts show a pattern. I repeated the two lists for the other 19 top accounts. Cloud came up in 9 of them.
The Account Wallet Map
List what each top account bought from you
The last three years, by service line. Use what you actually billed, not what is on your capability deck.
Ask the KAM where their budget is growing this year
Not from an analyst report. If the KAM does not know, the first job is to go and find out.
Count the overlap for each account
How much of where they are spending more is something you can bill against today.
Look for the theme across all 20
A spending area that shows up in many accounts — like cloud in 9 of 20 — is a decision for the founder, not a lead list for sales.
One page to the founder, three options
A cross-account theme needs a founder decision before it needs a sales push. What went to the founder was one page: cloud, the 9 accounts attached, and three options.
Build it
Create the capability in-house. Slowest, highest margin, and the right call only if the theme is durable across many accounts.
Partner for it
Deliver with a specialist and stay the account's main relationship. Faster, lower margin, keeps you in the conversation.
Reposition what you already sell
Reframe existing services — testing, support, development — around where the budget is going, such as testing and support for migrated workloads.
Nothing went to the sales team to chase until he chose. Sending salespeople after a budget the company cannot yet serve produces conversations, not revenue.
Two ways to grow inside a customer
Account growth comes from one of two moves, and most IT services companies only run the first. You can get the customer to spend more on what you already sell. Or you can become relevant to more of what they already spend.
When the customer's budget grows somewhere you are not, selling harder on what you already do will not follow the money
