NHA works as a retained strategic partner for one client per sector, per geography. No commissions. No conflicts. No cost-cutting. Pure commercial growth.
Every NHA engagement is led by Paul Foster. No junior teams. No methodology frameworks handed off to associates. The commercial experience you engage is the commercial experience you receive.
Identifying where revenue growth is possible, what is blocking it, and what a commercially structured response looks like. Built from your numbers, your market, and your competitive position.
Designing the BD engine, not just the immediate pipeline. Target identification, proposition development, approach strategy, and commercial model, built to work without NHA once embedded.
Finding margin that is being left on the table through cost mismanagement, supplier relationships, or commercial terms that no longer reflect your leverage. Quantified and recoverable.
NHA operates a single retained client per sector per geography model. This is not a policy, it is the foundation of the practice.
Margin pressure, digital substitution, sustainability compliance.
02CBAM exposure, R&D pipeline, export market development.
03Strategic account retention, rebid preparation, scope expansion.
04Partnership positioning, key account strategy, cross-sell architecture.
05Broker and reseller BD strategy, proposition differentiation.
06Managed services growth, channel strategy, enterprise targeting.
07Framework positioning, repeat client strategy, supply chain BD.
08Carbon border adjustment, export positioning, strategic account growth.
NHA operates on a retainer plus performance bonus structure. The retainer funds the ongoing advisory relationship. The performance bonus is tied exclusively to verified, incremental commercial outcomes above a Pre-Engagement Benchmark Declaration established before any NHA advice is given.
This means our interests are fully aligned with yours from day one. NHA only earns its performance fee when you earn more than you were already planning to.
A 30-day Assessment Period applies to all engagements. If NHA withdraws within that period, the client pays nothing.
NHA engages a small number of retained clients at any one time. If your sector is listed above and you would like to have a direct conversation with Paul Foster, please get in touch.

Nathan Harmer Associates was not built from a methodology. It was built from 49 years of doing it. Paul Foster has spent his entire career in commercial roles — not consulting about them. He has run national sales teams, managed business development in strategic accounts worth £250M, built BD programmes from scratch, and sat in the room when the decisions were made.
NHA is the vehicle through which that experience is made available to a small number of retained clients at any one time. There are no junior teams. No account managers. No delivery frameworks handed to people who weren't in the room. Paul leads every engagement personally from first conversation to final outcome.
“I have spent 35 years doing this. Not advising people how to do it. Actually doing it. NHA was built on the commercial intelligence that only comes from being inside the room, running the programme, and carrying the number.”Paul Foster — Principal Architect, Nathan Harmer Associates

Book a ConversationThe RCGA framework: Retain, Convert, Grow, Acquire. Four disciplines. One retained client per sector. Personal delivery throughout.
Most BD programmes focus on acquisition. NHA's RCGA framework starts where the money already is — in your existing client base — and works outward. Convert is a particularly critical and often absent stage: the conversion of a retained client relationship into a significantly larger strategic account.
Protecting existing revenue by identifying and addressing the commercial risks that make retained clients vulnerable to attrition. Relationship mapping, value evidence, competitive threat assessment.
Elevating a retained transactional relationship into a strategic partnership. The Barclays case study is the proof of concept: a single-division contract retained and converted to a full Group strategic partnership over five years.
Structured expansion of existing strategic accounts through new service lines, divisional penetration, and scope growth. Revenue that doesn't require winning a new client.
Targeted new client acquisition through commercial intelligence, precise proposition development, and a BD programme built around the clients most likely to become strategic accounts.
A 30-minute direct conversation with Paul Foster. No slides. No pitch. An honest assessment of whether there is a commercial fit between your situation and what NHA does.
Before any NHA advice is given, we establish in writing your existing commercial plans, pipeline, and targets. This is the PEBD — the baseline against which all NHA performance is subsequently measured. You cannot be charged a performance fee for something you were already going to achieve.
NHA conducts a structured assessment of your commercial position, existing relationships, pipeline quality, and market opportunity. At the end of this period, NHA either commits to a full engagement or withdraws. If NHA withdraws, you pay nothing.
A formal retained engagement under the NHA Client Engagement Agreement. Monthly retainer plus a performance bonus structure tied to verified incremental revenue above the PEBD baseline.
Permanent access to Paul Foster for commercial strategy, BD architecture, proposition development, key account management, and opportunity assessment. NHA is a retained commercial partner, not a project resource.
NHA accepts no commissions, referral fees, kickbacks, or supplier incentives under any circumstances. Our fee comes only from you. Our advice goes only to you. There are no conflicts of interest because there is no structural mechanism through which a conflict could arise.
This is not a differentiator. It is a prerequisite for giving genuine commercial advice.

Volume pressure, digital substitution, sustainability compliance driving structural margin compression.
The commercial challenge in print and packaging is no longer primarily operational. Clients are consolidating supply chains, reducing print volumes, and applying sustainability obligations that disproportionately affect suppliers without verified carbon data or a credible environmental proposition.
NHA works with printing and packaging businesses to arrest retention risk on existing strategic accounts, develop commercial propositions that compete on value rather than price, and position the business ahead of EPR and CBAM requirements as a commercial differentiator.

In 2004, Paul Foster was recruited back to Communisis Group by Denise Moran specifically to manage Barclays business development. Communisis held a contract with Barclaycard — one division of the wider Barclays Group. The contract was under competitive pressure at renewal and the relationship existed almost entirely at an operational level. The strategic opportunity was visible but entirely unaddressed. And without intervention, there was a real risk of losing what it already had.
The first and most critical stage was retention. The Barclaycard contract was secured by elevating the relationship from operational to strategic, building a value case that made switching cost prohibitive and introducing executive-level contact points above the procurement layer.
Once retained, the Convert stage was executed: mapping the full Group structure, identifying commercial sponsors at a senior level, and building a cross-divisional proposition at Group scale. HSBC and Sainsbury's were subsequently added using the same methodology.
Before NHA begins any engagement, we establish your existing commercial plans in writing. The performance bonus is only payable on revenue above that baseline. You cannot be charged for results you were already going to achieve.

Principles Applied
Providian National Bank was a US-originating consumer credit card business targeting the near-prime and sub-prime UK market. The operation required complex, high-volume, compliance-critical customer communications work that several suppliers had declined to take on. The account came through Dean Smith, who referred Paul to Lucy Holland, Providian's senior marketing operations contact.
The account was not won through a competitive pitch. It was won through a specific act of commitment: taking on a data processing problem that other suppliers had declined to handle and solving it without conditions. That single unconditional act established the relationship on a foundation of trust that every subsequent commercial interaction was built on.
The account grew to approximately £3M per annum and ran until Providian's UK operation was acquired by Barclaycard in 2002. What Barclaycard acquired was the client book. What it did not acquire was the loyalty of the team that had built and run the Providian operation. Lucy Holland subsequently moved to establish Vanquis Bank. The Vanquis account followed the relationship. See CS-003.
A client won not through marketing spend, competitive process, or price, but through a single act of commercial commitment that no competitor was prepared to match. The relationship equity built here survived a corporate acquisition and transferred across two employers. Every committed action builds future pipeline.

Geography: UK

Principles Applied
Vanquis Bank was established by Provident Financial PLC to serve the same near-prime consumer credit market that Providian had targeted. Lucy Holland — Paul Foster's key contact at Providian — moved to Vanquis with responsibility for the same workstreams. By this point, Paul was Managing Director of Navigator Communications. The question was not whether Lucy would consider another supplier. The question, which she had already answered through her behaviour, was whether the person she trusted had moved with the market.
There was no approach in the conventional sense. No pitch, no tender, no competitive process. The relationship built at Providian — founded on the unconditional commitment that won the original account — transferred across the corporate boundary when Lucy Holland moved employers. Navigator Communications received the Vanquis account because one person trusted another person, and that trust was portable.
When Paul subsequently left Navigator Communications, the Vanquis account did not stay. It left because he had. The value at departure is the most precise measure of the value that had been built.
The relationship equity built at Providian through a single unconditional act survived a corporate acquisition, transferred across two employers, and generated £2M of acquisition-stage revenue at zero prospecting cost. This is the RCGA Acquire component at its most concentrated: not prospecting, not marketing, not pitching — but relationship equity, built deliberately, that compounds across time and organisations.

How finance dismantled the sales function — and what it costs every year it stays broken
Over thirty years, the finance function progressively dismantled the integrated commercial and sales capability of the British mid-market business. It did this with the best of intentions, using perfectly legitimate tools, and the damage it caused has been structurally invisible to most boards until the moment it became a crisis. This paper explains how it happened, why it persists, and what a commercial strategy that corrects for it looks like.
When finance applies its measurement framework to sales and BD, it captures what is measurable and misses what is not. Revenue generated this quarter is measurable. The depth of a client relationship that will determine whether a contract renews in eighteen months is not. The institutional knowledge held by a senior account manager who has been calling on a client for a decade is not.
The thirty-year mistake is the progressive elimination of everything that does not appear in the measurement framework, in the name of efficiency. Senior account managers replaced by junior ones. Relationship development time replaced by call rate targets. Strategic client conversations replaced by quarterly business reviews structured around the supplier's reporting requirements rather than the client's commercial priorities. Each individual decision looks defensible in a spreadsheet. The cumulative effect is the erosion of the commercial capability that generates renewal, expansion, and referral.
Every restructuring cycle removes a layer of commercial experience. Successors inherit a CRM record. They do not inherit twenty years of context that made those records meaningful.
The most powerful commercial conversations happen when the person who can solve the problem is the same person having the commercial conversation. Structural separation destroys this.
Strategic account development requires investment of senior time that does not produce measurable return quarterly. Finance eliminates the investment before the return arrives.
As suppliers reduced commercial investment, buyers replaced relationship-based purchasing with process-based procurement. The relationship advantage that took decades to build was superseded by a matrix treating all suppliers as interchangeable.
The thirty-year mistake persists because it is invisible from inside the measurement framework that created it. When commercial performance deteriorates, the standard response is a sales process intervention: a new CRM system, a new pipeline methodology, a new sales director. These interventions address the visible symptoms and leave the structural cause untouched.
“The finance function did not set out to damage commercial capability. It set out to manage cost. The two things turned out to be the same, and it took thirty years for most boards to notice.”

What genuinely dysfunctional environments reveal about commercial leadership
Most senior commercial leaders spend their careers in organisations that more or less function. The conditions that make sales and business development possible are simply assumed. They should not be. The most important commercial lessons are learned in the places where none of those conditions exist. This paper is about what a burning building teaches, and why the principles extracted from those conditions are more durable than anything learned in a stable environment.
A burning building in commercial terms is a specific set of conditions: no coherent management structure; financial controls that manage appearances rather than performance; clients who are already leaving; a leadership culture of blame avoidance; unreasonable demands with no structural support to meet them. This is more common than leadership literature acknowledges.
Clients who have been let down are not irrational. Their scepticism has been earned. The only path back is specificity and consistency: precise undertakings, delivered without exception. The relationship does not recover in a meeting. It recovers across dozens of interactions, each of which either builds or destroys the accumulated trust balance.
Client recovery is immediate and backward-looking. New commercial development is strategic and forward-looking. A burning building removes the luxury of sequencing them. The commercial leader who has operated at both speeds in genuine crisis is structurally better at prioritisation than one who has only ever worked in comfortable conditions.
Attempting to fix the organisation while simultaneously serving the client produces failure at both. In a stable environment, where the consequences of this error are less visible, the same discipline produces a sustained competitive advantage that most competitors are not replicating.
“The worst environments produce the clearest thinking. When nothing works, you discover very quickly what commercial leadership actually requires, and what was simply comfortable habit.”

Why sustainability investment fails commercially, and what the missing component always is
Thousands of mid-market businesses are making significant investments in sustainability credentials — verified carbon accounting, product carbon footprints, ISO certification, chain of custody, independent audit. The technical work is sound. The commercial return is absent. The reason is consistent: the credentials were built facing inward, towards compliance, and nobody built the commercial architecture facing outward, towards the market. The investment sits on the balance sheet as a cost. It should be generating revenue.
The terminology of sustainability — carbon neutral, net zero, climate positive — is increasingly toxic in corporate legal departments. Not because the claims are false. Because interpretation in consumer protection law bears no relationship to technical meaning. The credentials survived. The proposition did not.
Procurement departments exist to optimise cost. When a sustainability premium appears as a line item, the response is predictable: remove it. The people who want the credentials do not control the budget. The people who control the budget do not understand why they should pay for them.
The sustainability professional speaks in tonnes of CO² equivalent and lifecycle assessment scope boundaries. The commercial buyer has two questions: Why should I care? And how does this help me sell more? Neither is answered by a verification certificate. Both must be answered before the buying decision is made.
The EU CBAM entered its definitive period in January 2026. The UK CBAM goes live January 2027. Extended Producer Responsibility is already generating invoices. Digital Product Passports are mandatory across an expanding range of EU product categories. In each case the structure is identical: a regulatory requirement generates a compliance investment, the credentials sit in a compliance function without a commercial strategy, and the investment returns nothing beyond avoiding a penalty. The businesses that generate commercial return are the ones that treat compliance investment as the foundation of a sales proposition.
“The credentials are real. The verification is rigorous. The market does not respond. The diagnosis is almost always the same: nobody answered the question every buyer actually asks. Why should I care? And how does this help me sell more?”
