The firm below — Hartwell & Co. — is a composite. The practice doesn't exist; the journey, numbers, and progression are calibrated to real SME advisory engagements and to the design of the BIP Founding Partner program. This piece illustrates how a small UK accounting practice would execute the program in its first 90 days — and the Year-1 trajectory that follows. The structure mirrors the three tiers in the BI Service Stack Planner: Diagnostic (Baseline) → Operating Layer (Foundation + Rhythm) → Strategic Partner (Evolution).
Hartwell & Co. — a chartered accounting practice in the UK Lake District. Seven staff: three partners, four associates. £1.4M annual revenue. Around 90 SME clients on the books, mostly hospitality, professional services, and light manufacturing across North-West England. Steady, well-run, profitable.
Three months ago, the senior partner had a recurring problem. Every quarter, two or three clients would ask the same kind of question: "we're growing — should we be hiring? what's actually our margin on the corporate retainer work? how exposed are we to that one big customer?" Compliance work didn't answer it. The firm referred the work out, lost the revenue, and watched the relationship cool.
The firm had considered building a BI capability internally. The math didn't work. Hiring an analyst was £55K+ per year. Buying licences for a Power BI stack added another sales cycle. Building IP — frameworks, dashboards, intake processes — would take 12–18 months. By the end of that runway, the practice would have spent six figures and learned what they already knew: SME owners want clarity, not consulting projects.
So Hartwell joined the Founding Partner Program instead. Here's how the first 90 days went, and the trajectory it puts the firm on for Year 1.
The firm at a glance
The 90-day journey
Days 1–10 · Onboarding
The senior partner blocks 12 hours across two weeks. BIP Method™ certification is self-paced — they work through the four stages (Baseline → Foundation → Rhythm → Evolution), the white-label diagnostic template, and the data-dictionary scaffolds. They review the Sample Review and the BI Service Stack Planner with one of the associates who'll handle delivery.
By day 10, the firm has the playbook, the templates, and a draft "BI Advisory" line item ready to add to client conversations. No revenue yet — but the next call with a client is now a different conversation.
Days 11–30 · First Tier 1 Diagnostic
An existing client — a 12-person bakery chain doing £2.1M in revenue across four sites — is the first candidate. They've been asking about per-site margin for over a year. Hartwell scopes a Tier 1 Diagnostic: $1,500, fixed price, five business days, written 8-page report.
The diagnostic surfaces three findings the existing reports never showed: one site running at a 9% margin (vs. the assumed group average of 22%), £38K of working capital trapped in slow-moving stock, and a customer-mix shift toward lower-margin corporate catering. The client signs the project. Hartwell delivers in five business days. The senior partner spends 9 hours on it; the associate spends 4. Total cost to the firm: ~$1,040 in time at a $80/hr loaded rate.
Days 31–60 · Two more Diagnostics + first Tier 2 conversation
The bakery client comes back wanting more — they want the per-site margin tracked monthly with a decision rhythm attached. Hartwell scopes a Tier 2 Operating Layer: 6-week build at $4,500, then $900/month retainer. The build starts in week 8.
In parallel, two more Tier 1 Diagnostics ship: a 6-person consultancy struggling with project pipeline visibility, and a small hospitality group wanting to understand cost-of-goods volatility. Both at $1,500. The associate handles most of the analytical work; the senior partner reviews and presents.
By day 60, the firm has shipped 3 Tier 1s for $4,500 in total revenue, and has its first Tier 2 in flight. Time invested across the three Diagnostics: 27 hours. The pattern is starting to look like a service line — not a side project.
Days 61–90 · First Tier 2 Build live + retainer starts
The bakery's Tier 2 build wraps in week 13: a data dictionary covering the 8 metrics that matter, weekly per-site margin reports, a monthly review meeting structure, and threshold rules that trigger conversations when a site drops below target. The associate runs the first monthly review on day 87. The retainer kicks in: $900/month, 5 hours of work.
The third Tier 1 ships in the same window. A fourth client — a 4-person professional-services firm — has booked a Tier 1 for the following week. By day 90, Hartwell has booked $9,900 in BI revenue, has one active Tier 2 retainer, and has three more clients in active scoping.
The 90-day numbers
| Line | Hours | Revenue |
|---|---|---|
| Onboarding (BIP Method™ certification + setup) | 12 | — |
| 3 × Tier 1 Diagnostic ($1,500 each) | 27 | $4,500 |
| 1 × Tier 2 Build ($4,500) | 25 | $4,500 |
| 1 × Tier 2 Retainer (1 month at $900) | 5 | $900 |
| 90-day total | 69 | $9,900 |
69 hours across 90 days is roughly 5–6 hours per week — comfortably absorbed by the senior partner and one associate. Effective realised rate including onboarding overhead: $143/hour. Excluding onboarding (delivery-only): $174/hour. Both numbers are well above the firm's average compliance-work hourly economics.
The Founding Partner program cost in the same period: $499 setup + 3 × $49 monthly = $646. The program paid for itself before the second Diagnostic shipped.
The Year 1 trajectory
Carrying the 90-day pattern forward — same conversion ratios, same execution rhythm, no hires — the Year 1 picture looks like this:
| Tier | Activity | Year 1 revenue |
|---|---|---|
| Tier 1 Diagnostic | 6 engagements across the year | $9,000 |
| Tier 2 Build | 3 builds (started across months 4–10) | $13,500 |
| Tier 2 Retainer | 3 retainers, average 6 months active each | $16,200 |
| Year 1 total advisory revenue from the BI service line | $38,700 | |
Around 150 hours of senior-partner-and-associate time across the year — about 9% of one senior practitioner's annual capacity. After the $80/hr loaded time cost ($12,000) and the $1,087 BIP Founding investment (Year 1), net margin lands around $25,600 — a 66% effective margin on the BI service line.
Year 2 looks materially better. Three retainers carry forward. One client elevates to Tier 3 (Strategic Partner) at $2,250/month. New Tier 1 Diagnostics keep the top of the funnel filled. Modelled forward at the same conversion ratios, the firm sees ~$52,000 in Year 2 BI revenue at a 70%+ margin.
What this means for similar firms
Hartwell's pattern isn't unusual. The economics of advisor-delivered BI compound for a specific reason: the Operating Layer is productized (templates, dictionaries, report scaffolds, monthly review structure) and the Strategic Partner tier is leveraged (one quarterly Evolution review covers a quarter of advisory). Each new client costs a fraction of the first. The firm doesn't hire data people. It uses the playbook.
Three things made the difference for Hartwell in the first 90 days:
- The first Diagnostic wasn't a sales pitch — it was a deliverable. $1,500, five days, written report. The bakery client paid for it because it answered the question they'd been asking for a year. That's the Tier 1 mechanic.
- The Tier 2 conversation came from the Tier 1 findings, not a sales call. Once the client saw what was possible, they wanted it institutionalised. The progression Tier 1 → Tier 2 didn't require pitching — it required delivery.
- The firm didn't build IP. They licensed it. The Founding Partner toolkit handed Hartwell the framework, templates, and Method certification. The firm's effort went into client work, not building infrastructure they'd reinvent badly.
The full economics for a wider range of client profiles are mapped in the BI Service Stack Planner — including the Meridian Creative composite at the SME end ($2.7M creative agency, $14K Year-1 advisor revenue per client, $27,600 18-month total). Hartwell sits at the firm-level: how the playbook compounds across a 90-client book.
Where Hartwell is going
The firm's Year 2 plan is on the wall: hold the three Tier 2 retainers, elevate the bakery client to Tier 3 in month 13, sign 4 more Tier 1 Diagnostics, and convert at least one to Tier 2 by month 18. The senior partner spends 12% of their time on the BI service line. The associate spends 25% of theirs. No new hires. The economics fund themselves from month 4 onward.
Two years in, the firm projects ~$90K of cumulative new advisory revenue at a >65% margin — without expanding headcount, without buying enterprise BI software, and without referring the work to a consultancy that doesn't know the client.
That's the Founding Partner thesis, applied. The math is the math.
25 spots. $499 setup + $49/mo. Locked for life.
Founding Partners receive the BIP Method™ certification, the BI Without the BS toolkit, white-label rights to The Review, the BI Service Stack Planner, and a private partner support channel. After the 25th spot, the program moves to standard pricing ($999 + $99/mo).
