Problems › We Do Not Know Who Our Best Customers Are › Banks & Financial Services
Best does not mean largest. It means the ones you can acquire repeatably, serve profitably and keep. This page works through it for banks and financial services firms specifically — including an unedited excerpt from a real analysis of a bank.
Best does not mean largest. It means the ones you can acquire repeatably, serve profitably and keep. Banks and financial services firms carry a specific bind here — the branch network is simultaneously the deposit moat and the cost problem — and the relationship knowledge sits in six people close to retirement. Until that is priced, efficiency ratio will keep moving for reasons nobody can attribute, and the debate about contribution by segment will stay a matter of opinion.
Most businesses can name their biggest customers and very few can name their best, because best requires combining three things that usually live in different systems: what they contribute, what they cost to acquire, and how long they stay.
The results are consistently surprising. The largest accounts are frequently mid-ranked once cost to serve is included; the best segment is often one nobody targeted deliberately, discovered by accident and never systematised.
This matters because it decides everything downstream. Who to target, what to build next, where to price, what to say. Getting it wrong means optimising the entire business for the wrong customer.
These three together are the signature. One on its own usually points somewhere else.
✓ Best customer means largest by revenue in internal conversation
✓ Cost to acquire is not known by segment
✓ The ideal customer profile was written from intuition rather than from the base
The move that usually makes it worse. Defining the ideal customer from the largest accounts, which selects for the ones with the most negotiating power rather than the best economics.
It is for you if you run or finance a bank and best customer means largest by revenue in internal conversation. It is the situation where the numbers are available but nobody has put them in an order that produces a decision.
It is not for you if Percision is the wrong tool if you already know the answer and only need execution capacity, or if the business is pre-revenue — then the constraint is evidence about the market, not analysis of your own figures. Percision is not a lawyer, tax advisor, auditor, licensed appraiser, clinical or regulatory filer, or an AI implementation shop. It does not do HR casework, creative-only brand work, or impersonate a named consulting firm. It is a strategy analysis engine — not a template library. Also wrong if you need facilitation, politics, or someone to sit with a lender or buyer. Those are human jobs.

Below is an excerpt from a real run of this analysis on a bank. It is a sample profile rather than a customer, and it is unedited engine output — this is the format you get, on your own numbers.
The subject is Harborline Financial Group, a sample company profile used for testing rather than a customer — $3.1B commercial lending book, $410M of deposits.

The move. Turn 71% of commercial borrowers into treasury customers at 65% contribution margin using existing branches and the 2027 core renewal.
The leak it closes. Reduces value transfer to fintech treasury platforms by locking 425 accounts into integrated deposit-lending workflow
The assumption it rests on. Core banking processor grants API depth at no incremental cost during 2027 renewal — the engine put the probability at 0.7.
| Investment required | $4–6M over 24 months ($2.5M technology integration, $1.5M 8 FTE hiring & training, $1M compliance & SOC-2 certification) |
| Expected return | 5.5× — $11M 5-year NPV on $5M investment |
| Revenue, year 1 | $0.45M incremental fee income (75 accounts × $4,200 × 65% margin × 6 months) |
| Revenue, year 2 | $1.79M incremental fee income (425 accounts × $4,200 × 65% margin) |
| Revenue, year 3 | $3.57M incremental fee income (850 accounts × $4,200 × 65% margin) |
| Exit criteria | Halt treasury build and reallocate remaining capital to SBA lending if (a) penetration <15% of overlap accounts by Month 18 OR (b) cumulative fee income < $800K by Month 18 OR (c) core-processor renewal does not include API depth clause by Month 6 |

This question routes to Customer Value Architecture, one of 29 engagements the platform runs. For banks and financial services firms it works through efficiency ratio, cost of funds, origination per banker and deposit concentration, then produces the sequence rather than a list of options — which move first, what it funds, and the observation that would say the sequence is wrong.
You watch the analysis get built before paying anything. Read a complete report here if you would rather see the depth first.
Combine contribution, acquisition cost and retention at the segment level. Any one of the three alone produces a ranking that is confidently wrong.
That is usually good news — it is a targeting instruction. The relevant question is whether the segment is large enough to support your growth plan, which is answerable.
Reprice first; some become profitable and the rest leave with the decision made for you. Firing directly is faster and costs you the information about which were repriceable.
Materially, yes. The branch network is simultaneously the deposit moat and the cost problem — and the relationship knowledge sits in six people close to retirement — which changes both the diagnosis and the order of the fixes. The metrics that decide it here are efficiency ratio, cost of funds, origination per banker, and an answer built on industry-general benchmarks will usually point at the wrong one first.
Less than most people expect. Your last twelve months of revenue and cost split the way you already split it, plus whatever you hold on efficiency ratio and cost of funds. The analysis is explicit about what it is assuming where your data stops, which is more useful than waiting for numbers you may never have.
