Good/better/best - also known as anchored tiered pricing - is the single most well-documented sales structure in commercial pricing research. Software companies use it. Insurance companies use it. Premium hotel chains use it. Yet most UK accounting firms still present pricing as either a single quoted figure or a complex a-la-carte menu, missing the conversion-rate and margin benefits that three-tier structure consistently produces.
This guide covers the why, the how, and the operational discipline behind running a successful three-tier model in a UK practice. The structure is simple. The discipline to maintain it - to resist the urge to add a fourth tier, to keep the middle tier dominant, to enforce scope boundaries - is what separates firms that benefit from the model from firms that quietly let it degenerate back into ad-hoc pricing.
The psychology: why three tiers work
When a buyer is presented with one option, the decision is "yes or no" - and the default human response to uncertainty is no. When presented with two options, the decision becomes "cheap or expensive" - and most buyers default to cheap. When presented with three options structured as good/better/best, the decision becomes "which one suits me?" - and roughly 60-70% of buyers pick the middle option, with another 15-20% picking the top tier.
The middle tier is therefore the anchor. It should be designed to be the option you most want clients to pick. The top tier exists to make the middle look reasonable. The bottom tier exists to give price-sensitive buyers an entry point without losing them entirely.
Structuring the three tiers: progressive value, not added features
The most common mistake is structuring the tiers as a feature checklist where each higher tier "adds" features. This works for software but feels mercenary for professional services. Instead, structure the tiers as progressive outcomes: the bottom tier covers regulatory compliance, the middle tier adds management visibility and proactive support, and the top tier adds strategic advisory and senior partner attention.
Each tier should sound like a different relationship with the firm, not just a longer feature list. "We handle your compliance" → "We are your finance partner" → "We sit on your leadership team." This framing keeps the conversation about value and outcomes rather than line-item features.
Pricing the tiers: the 1x / 2.5x / 5x ratio
A clean pricing ratio across the three tiers is roughly 1x / 2.5x / 5x. If the bottom tier is £500/month, the middle is £1,250 and the top is £2,500. The spread is wide enough that the tiers feel genuinely different, and the middle tier sits visually closer to the bottom than the top, which encourages clients to "stretch up" to the middle.
Avoid ratios that compress the tiers (e.g. £500 / £700 / £1,000). When tiers are too close in price, clients perceive minimal differentiation and either pick the cheapest or get stuck in analysis paralysis. The wide ratio works precisely because it makes the choice feel meaningful.
Naming the tiers: avoid Bronze/Silver/Gold
Bronze/Silver/Gold is the laziest tier-naming convention in professional services. It signals to the buyer that you copied the structure from a hotel loyalty programme. More importantly, it positions the bottom tier as inferior - which makes clients defensive about picking it and reluctant to discuss the tiers at all.
Better naming patterns reflect the outcome of each tier: Essentials / Growth / Premium, Compliance / Clarity / Catalyst, Foundation / Partner / Leadership. Whatever you pick, the names should communicate progression of value, not progression of metal.
What goes inside each tier: scoping discipline
For each tier, write a one-page scope sheet with: included services, frequency of each service, response-time SLA, meetings per year, named contact at the firm, and the explicit exclusion list. The exclusion list is what protects margin - anything not on the inclusion list is quoted separately at the standard hourly rate.
The middle tier should be the most carefully scoped. It will carry the majority of your book and will be the most common subject of scope-creep pressure. Be specific about meeting lengths, deliverable formats, and what does and does not count as "included support". Vague middle-tier scoping is the single most common reason firms find their middle tier under-recovering at 75-80%.
Operating the tiers: realisation discipline
Once tiers are live, run realisation analytics by tier every quarter. Hours delivered versus budgeted hours, captured silently against each engagement in the practice-management layer, tell you immediately if a tier is being priced or scoped incorrectly. If the middle tier consistently runs at 75% realisation, either the scope is too broad or the price is too low. Adjust at the next annual review.
The firm sets the price, scopes the deliverables, and bills through Xero, Sage or whichever invoicing tool runs the cash. The analytics surface the data; the partners make the call. Doing this quarterly is what stops a well-designed tier structure from quietly degrading into the loose ad-hoc pricing it was meant to replace.
Migrating existing clients into the tier structure
Do not move every existing client into the new tier menu on day one. Use the next 12-month renewal cycle as the migration window. As each client comes up for renewal, present the new three-tier menu and recommend the tier that best matches the work they have actually been receiving. Most clients accept the recommendation because the tier they end up on is roughly what they were already paying for, just with a clearer scope and a small upward adjustment.
Expect 5-10% to push back; hold the line on 80% of those. The minority who simply cannot or will not move are typically the clients you wanted to migrate out anyway. Replacing them with new clients onboarded straight onto the tier menu rebuilds the book faster than most partners expect.
Resisting the fourth tier (and the fifth)
The discipline that breaks tier structures is "tier inflation" - partners proposing a fourth tier "between Growth and Premium for the ones who don't quite need Premium", or a "Premium Plus" for the very biggest clients. Every additional tier dilutes the conversion-rate benefit of the three-tier structure and reintroduces decision paralysis.
Three tiers, full stop. If a client needs something genuinely beyond the top tier, that becomes a custom engagement scoped and quoted separately - not a new public tier. Hold this line for at least three years before considering any structural changes.
Closing
Three-tier good/better/best is the most reliable conversion-rate and margin-mix structure available to a professional services firm. Build the three tiers around progressive outcomes, price them at roughly 1x/2.5x/5x, name them for value rather than metal, scope the middle tier with extreme care, migrate existing clients through the renewal cycle, and review realisation by tier every quarter. Firms that adopt and maintain this structure typically see average fee per client rise 30-50% within 18 months while close rates on new prospects improve simultaneously.
