Tooling sits on top at £80 to £600 a month per workflow. After 120+ AI implementations across 15+ industries, those four numbers cover almost every honest engagement shape on the market. This post walks each band, names what changes the number up or down, and flags the line items most quotes hide. ## Four engagement shapes make up the bill Almost every UK SMB AI engagement settles into four shapes: an audit, a single first build, an implementation sprint of three to five builds, and an operating retainer that runs after the sprint. The four shapes are sequential. A prospect who skips the audit ends up paying for it inside the first build. A prospect who skips the retainer often loses the sprint inside six months as builds drift without the named owner reviewing outputs. The four numbers in the intro are the price for each shape on its own. Total spend in year one for a typical 10 to 50 person UK SMB lands between £20,000 and £80,000, of which £15,000 to £60,000 is consulting fees and the balance is tooling pass-through. ## The audit fee, and what it actually buys A WIRE Method audit costs £1,500 to £4,000 and runs across two to three working days. The output is a costed candidate list (six to twelve workflows scored on Time Tax in pounds and hours per quarter), a recommended first build with a written scope, a one-page success metric, and a tooling shortlist. The audit is fixed price. It is not a discovery workshop disguised as a deliverable, and it is not a deposit on a build. If a prospect does not move forward to a build, the audit document is theirs to keep and use. About one in three audits ends there, and the result is still better than the same prospect spending £15,000 on a strategy deck that nobody acts on. ## The first build: what £3,500 to £9,000 actually ships A first build is a single working automation, deployed by Friday of week one of the build engagement, and reviewed across the following two weeks. The fee covers the build itself, the prompt or scenario engineering, the integration into a real data source, the handover document and the fortnight of output review. The lower end (£3,500) is a Custom GPT or a Claude Project plus prompts. The middle (£5,000 to £6,500) is a Make or Zapier scenario plus an LLM step plus a CRM or Slack endpoint. The upper end (£9,000) is a multi-trigger automation reading from one source and posting to two destinations with a named human in the review loop. None of these need a model trained, infrastructure provisioned or a vector store tuned. ## The implementation sprint: £12,000 to £35,000 The sprint is the bulk-build engagement. Three to five working automations across six to eight weeks, each with its own named owner, success metric and review cadence. Pricing scales with the number of builds and the integration complexity. A three-build sprint at £12,000 covers three Custom GPTs or three single-step automations on the same SaaS stack. A five-build sprint at £35,000 covers five automations with multi-system integration, structured handover and team training. The sprint is where most UK SMBs spend the bulk of their year-one AI budget. The honest test on a sprint quote: the document should list the five workflows by name, the named owner per workflow, the trigger, the review cadence and the rough hours saved per workflow per week. If those five fields are missing, the sprint will not survive month four. ## The operating retainer: what you pay after the build A retainer covers the ongoing work after the sprint closes: new builds, prompt updates, output review on existing automations, team training, governance review and access to the practitioner for inbound questions. UK SMB retainers run £4,000 to £15,000 a month. The lower band buys two to four hours a week of practitioner time plus async support. The middle band (£8,000 to £10,000) buys a day a week of build work plus monthly governance review. The upper band buys the equivalent of a fractional Chief AI Officer for a £5m to £20m revenue business. The retainer is optional. Plenty of clients run their builds without one after the handover. The honest test for whether to take a retainer: count the workflows running and divide by the named owner. If the ratio is over three workflows per owner, take the retainer. ## Tooling pass-through: the line item most quotes hide A working AI build runs on tools the client pays for: Claude Pro or Team, ChatGPT Plus or Team, a Zapier or Make subscription, the CRM the data lives in, and sometimes an API spend on the model behind the build. Across an SMB stack, tooling runs £80 to £600 a month per active workflow. A consulting quote that does not name the tooling cost is hiding it. The tooling sits on the client billing card, not the consultant invoice, which is the right structure (it survives the consultant leaving). A typical 10 to 50 person UK SMB lands at £400 to £2,500 a month of tooling across the full stack once three to five builds are running. ## What changes the number up or down - Regulated data: SRA, FCA or healthcare workflows add 30 to 50 percent to build cost for the additional review and the named owner pattern. - Existing documentation: a workflow already documented in production form ships at the lower end of the band; an undocumented workflow needs a paid documentation step first. - Tooling already in place: a client on Claude Team, Zapier Pro and a clean CRM ships builds 20 to 30 percent faster than a client buying tools fresh. - Number of named owners on the client side: a single owner for three builds compresses the engagement; three owners for three builds adds two to three weeks for handover and training. - Geographic and language scope: UK English only is the base; multi-language or multi-country compliance adds 15 to 25 percent. - Integration depth: API integration into a custom system adds £2,000 to £6,000 per build over the SaaS-only baseline. ## The fees a UK SMB should refuse Three patterns are worth refusing. A discovery workshop priced at £5,000 to £15,000 as a deliverable in its own right, rather than a deposit credited against the build, is a billable delay. A six-figure strategy phase ahead of any build, for a business with under £20m revenue, is almost always wrong shape. A retainer with no fixed deliverables, billed against vague monthly hours with no review cadence, is the most common way a healthy build relationship turns into drift. Refuse all three on the discovery call. The replacement structure is the one above: a fixed audit fee, a fixed first build fee, a fixed sprint fee with named workflows, and a retainer with monthly deliverables in writing. That structure is the WIRE Method commercial layer, and it is the one that survives the engagement closing without leaving the client owning nothing. ## Build your first AI system live with Richard A 60-minute live build with Richard Batt.
