Enterprise MVP Agency Pricing: What B2B Teams Should Budget and Ask in the RFP

Send the same enterprise MVP brief to four agencies and you will get back something like £38,000, £110,000, £240,000 and a polite request for a call. This is not because they are trying to mislead you, they are pricing four very different products, because your brief left four different gaps, and each agency filled those gaps with its own assumptions about discovery, integrations, accessibility and how many of your stakeholders will need to be in the room.

That gap is the single biggest source of procurement pain in enterprise product work. It is also entirely fixable. This guide gives you the realistic UK budget bands for an enterprise MVP in 2026, the variables that genuinely move the number, four worked scope examples with team shapes, and the RFP questions that force every bidder to price the same thing. By the end you will be able to set a defensible budget before you go to market, and read the proposals that come back with a much more sceptical eye.

Typical enterprise MVP budget ranges in the UK

Before the bands, a warning about the numbers you will find elsewhere. Most published UK MVP cost guides quote £8,000 to £30,000 for a simple build and £30,000 to £80,000 for a standard one. While those figures are solid, they also describe a startup MVP: one platform, three to five features, a founder who can make a decision in an afternoon, and no security review.

Enterprise conditions add cost that has nothing to do with the product itself. Single sign-on. A penetration test. A data protection impact assessment. Integration with a system nobody has documented since 2019. Legal review of the terms. Four stakeholder groups with competing definitions of "minimum". A procurement process that adds six weeks before a line of code is written. That is why enterprise numbers sit a tier above the startup guides, and why quoting a startup band inside a large organisation sets an expectation nobody can deliver against.

Here are the bands that actually hold up in the UK market in 2026when considering enterprise-based digital products. All figures exclude VAT, which UK agencies quote separately, so a £120,000 engagement is £144,000 against your budget line.

The bands overlap deliberately. A £75,000 project and a £200,000 project can both be honestly described as "MVP design plus front-end build", and the difference between them is usually integration count, accessibility standard and how many people have veto rights.

If a quote lands outside these bands, that is not automatically wrong, but it does need explaining. A £45,000 bid for a regulated enterprise platform is not a bargain, it is a misunderstanding that will surface as a change request in week eleven. A £400,000 bid for a two-integration internal tool is either gold-plating or a consultancy pricing its brand.

A quick way to sanity-check any number

Agency pricing is mostly arithmetic wearing a nice jacket. You can reverse-engineer almost any proposal with one formula:

Weekly burn = team size (in full-time equivalents) × blended day rate × 5

UK blended day rates for product design and engineering in 2026 run roughly £350 to £550 for regional teams and £600 to £900 for London agencies, with strategy consultancies charging considerably more per hour again. Freelance benchmarks give you the floor: contract senior product designers in the UK sit around £550 to £700 per day, and the median senior UX contractor rate has hovered near £500 to £550 for the past three years.

So a four-and-a-half person squad at a blended £700 per day burns £15,750 a week. Over a fourteen-week engagement that is £220,500, which is exactly why complex enterprise MVPs land where they land. Run the same maths on a proposal that promises a "full product team" for £60,000 over four months and you will find that the team is either one and a half people or somewhere with a very different cost base.

Do this calculation on every bid you receive. It takes ninety seconds and it tells you more than the executive summary.

What actually moves the price

Six variables account for most of the spread between a £40,000 engagement and a £250,000 one. When you write your RFP, be explicit about all six, because every ambiguity you leave becomes a padded contingency in someone's estimate.

Discovery depth

The cheapest discovery is a two-day workshop and a feature list. The most expensive involves ethnographic research across three user groups, stakeholder interviews across four business units, competitor teardowns, technical feasibility spikes and a service blueprint. Both are called discovery. One costs £6,000 and one costs £45,000.

For enterprise work, the middle of that range is usually right. The purpose of enterprise discovery is not to be thorough, it is to de-risk the decision to spend the build budget. If discovery costs 10 to 15 per cent of the expected build and it kills one bad feature or surfaces one integration nobody knew about, it has paid for itself several times over. We have never run a discovery that did not surface something the client team had not anticipated, and in enterprise environments the thing it surfaces is usually organisational rather than technical.

UX complexity

Complexity in enterprise products is rarely about the number of screens. It is about the number of states. A dashboard with four user roles, three permission levels, empty states, error states, loading states, partial-data states and an admin view is not one screen, it is forty. A consumer-style marketing flow with eight screens might take a designer two weeks. An operational tool with the same screen count and real data variability takes eight.

Ask any agency to tell you how they counted. If their estimate is expressed in screens rather than flows and states, they have underestimated you.

Integrations

This is the most reliable predictor of overrun in enterprise builds. Every integration carries three costs: the build itself, the discovery required to understand an undocumented system, and the waiting. Waiting for API credentials from a team that does not report to your sponsor is a real project cost, and good agencies price it.

A useful rule: budget for integrations at roughly the same rate as features, then add a contingency for every system you do not own. Salesforce, SAP, a legacy data warehouse and an internal auth service are four separate risk profiles, not one line item called "integrations".

Front-end build

Whether the agency stops at design or carries on into code changes the shape of the whole engagement. Design-only work can run with two or three people. Adding front-end delivery means engineers, a QA pass, a deployment pipeline, code review, environment setup and a handover process, which typically doubles both the team size and the calendar.

There is a hybrid worth knowing about: design plus a production-ready front end built against your APIs, with your in-house team owning the back end. For enterprise clients with capable platform teams, this is often the best value in the entire market, because you are buying the capability you lack rather than duplicating the one you have.

Accessibility

Accessibility is where enterprise budgets diverge most sharply from startup ones, and where the cheapest bids are usually cheapest because they have ignored it.

WCAG 2.1 Level AA is the standard referenced by most UK procurement frameworks and the Public Sector Bodies Accessibility Regulations, while WCAG 2.2 AA is the current published version and increasingly the enterprise baseline. If your organisation offers relevant products or services to EU consumers, the European Accessibility Act has applied to new services placed on the EU market since 28 June 2025 regardless of Brexit, with pre-existing services covered by a transitional period running to 2030. Penalties vary by member state and reach into the millions.

In practice, building to WCAG 2.2 AA from the start adds somewhere between 5 and 15 per cent to a design and front-end budget. Retrofitting it afterwards costs several times that and usually means redoing components you thought were finished. Any enterprise proposal that does not name an accessibility standard, an audit method and who signs it off is underpriced by design.

Governance

The final variable is the one nobody puts in the RFP. How many people need to approve the work? How often? Through which forum? An MVP with a single empowered product owner moves at roughly twice the speed of one with a steering group that meets fortnightly and a security team that reviews in batches.

Governance is not overhead the agency invents. It is time your organisation consumes, and it will be paid for either as an explicit line in the proposal or as a change request in month four. Better to name it up front.

Four example scopes and what they buy

Scope one: discovery and prototype only

Budget: £15,000 to £40,000. Duration: 4 to 8 weeks.

Team: a product strategist, a senior designer, a researcher part-time, with technical input as required. Roughly two to two and a half FTE.

You get user and stakeholder research, a clear problem definition, a clickable prototype that has been tested with real users rather than shown to colleagues, and a costed roadmap you can take to your investment board. This is the right first purchase when the business case is not yet signed off, when internal stakeholders disagree about what the product is, or when you need something tangible to unlock a larger budget.

This is also the honest answer to "we want to start small". It is not a discount MVP. It is a decision-making instrument. [internal link: discovery and prototyping → /discovery-prototyping]

Scope two: product strategy plus UX/UI design

Budget: £30,000 to £80,000. Duration: 8 to 14 weeks.

Team: product strategist, lead designer, UI designer, part-time researcher and delivery lead. Around three FTE.

You get the MVP designed in full: user flows, every state, a component library your engineers can build from, accessibility annotations, and a specification tight enough that an in-house or offshore team can execute it without inventing decisions. Buy this when you have engineering capacity but no product design capability, which describes a large share of enterprise IT functions. [internal link: UX and UI design → /uxui-design]

Scope three: MVP design plus front-end build

Budget: £75,000 to £200,000+. Duration: 12 to 20 weeks.

Team: the design team above plus two front-end engineers, a QA resource and a delivery lead. Four to five and a half FTE.

You get a working, deployed product front end integrated against your APIs, with a test suite, a deployment pipeline, documentation and a post-launch support window. This is the most common shape for a serious enterprise MVP where the organisation owns its own back-end platform.

The variance inside this band is almost entirely integrations and compliance. Two integrations and an internal user base puts you near £90,000. Six integrations, external customers, SSO, an accessibility audit and a penetration test puts you at the top.

Scope four: end-to-end enterprise product team

Budget: £150,000 to £350,000+. Duration: 20 to 32 weeks.

Team: product strategy, research, design, front-end and back-end engineering, QA, delivery management. Five to eight FTE, often structured as an embedded squad rather than a project.

You get the full build for a regulated, data-heavy or multi-system product, plus the governance capacity to survive an enterprise environment. This band is where financial services, healthcare and complex B2B platforms land, and where the day rate matters far less than whether the team can operate inside your organisation's constraints without stalling.

RFP questions enterprise buyers should ask

These are the questions that produce comparable bids. Group them exactly like this in your RFP document and ask for numbered responses, because it makes side-by-side comparison mechanical rather than interpretive.

On team and continuity

1. Name every person who will work on this engagement, their role, their seniority and their allocation as a percentage.

2. Which of the people in your pitch will be doing the delivery work, and for how much of the engagement?

3. What is your average tenure for senior design and engineering staff?

4. What happens if a named team member leaves mid-engagement? What is the handover process and who absorbs the ramp-up cost?

5. What proportion of the work is delivered by employees versus contractors versus offshore partners, and where are they located?

On scope, estimating and change

6. What assumptions have you made to produce this number? List them.

7. What is explicitly excluded from this price?

8. How did you estimate: by feature, by flow, by state, by sprint capacity?

9. What is your change control process, and at what point does a change become a variation rather than absorbed scope?

10. If discovery reveals the scope is materially different, do you re-price, and how?

11. What is your historical variance between initial estimate and final invoice across your last five projects of this size?

On technical approach and integration

12. Which integrations have you priced, and what did you assume about the state of documentation and access?

13. What do you need from us, by when, and what is the cost of a delay in receiving it?

14. What is your approach to technical spikes for unknowns, and are they inside or outside this price?

15. What testing is included: unit, integration, end-to-end, manual QA, user acceptance?

16. What does the codebase look like at handover, and what documentation comes with it?

On accessibility and compliance

17. Which accessibility standard are you building to, and is that stated in the contract?

18. How is accessibility tested: automated tooling, manual audit, assistive technology testing with users?

19. Who signs off accessibility conformance, and do you provide an accessibility statement?

20. What is your experience with our regulatory environment specifically?

21. How do you handle security review, penetration testing and data protection impact assessments? Included or excluded?

On governance and ways of working

22. How many hours per week do you need from our team, by role?

23. What is your escalation path when a decision is blocked on our side?

24. How do you report progress, how often, and to whom?

25. What does your onboarding period look like and is it billable?

26. How do you handle a steering group that changes direction mid-sprint?

On commercials, IP and exit

27. Is this fixed price, time and materials, or a hybrid? What triggers the switch?

28. What is your payment schedule and is any of it outcome-linked?

29. Who owns the IP, the code, the designs and the research outputs? From what point?

30. What third-party licences, tools or subscriptions are required, who pays for them and what do they cost annually?

31. What are your rates for post-launch support and iteration, and for how long are they held?

32. If we terminate at the end of any phase, what do we walk away with?

The single most revealing question on this list is number six. An agency that produces a clear, specific list of assumptions has thought about your project. One that says "we've assumed a standard build" has thought about their pipeline.

Red flags in agency proposals

A fixed price for a build with no discovery phase. Nobody can accurately price an enterprise integration they have not investigated. A fixed price without discovery is either padded with 40 per cent contingency, or it is a low number that will be corrected through change requests once you have signed.

A pitch team that will not be the delivery team. Common, rarely disclosed voluntarily, and the leading cause of disappointment in agency relationships. Ask for names and allocations in writing.

No accessibility line item. As covered above, this is not an omission, it is a cost transfer to you.

No QA or testing line. If testing does not appear in the breakdown, either it is not happening or it is happening in your UAT window at your expense.

An estimate priced to the pound. £147,382 is not more accurate than £150,000, it is theatre. Precision that the underlying method cannot support is a signal that the method is not being shown to you.

Design and engineering quoted as separate, sequential blocks with no overlap. Products built this way generate a handover gap where design decisions meet technical reality and one of them loses. Look for proposals that build in engineering involvement during design and design involvement during build.

No stated assumptions or exclusions. Covered above and worth repeating, because it is the fastest way to sort thoughtful bids from templated ones.

Unlimited revisions. This sounds generous and is usually a sign that revisions are not the constraint, because the work is being produced quickly and cheaply enough that redoing it does not hurt.

A day rate quoted without a team shape. "£850 per day" tells you nothing. £850 for whom, how many of them, for how many days?

Anything described as a proprietary accelerator that removes the need for discovery. Accelerators are real and can be genuinely useful for infrastructure and component libraries. They do not tell you what your users need.

How to compare agencies beyond day rate

Day rate is the least useful comparison metric in this entire process, because it tells you the price of an input rather than the cost of an outcome. A team at £900 a day that reaches a working product in fourteen weeks is dramatically cheaper than a team at £500 a day that takes twenty-eight. Here is what to weigh instead.

Effective cost per outcome. Take each bid, take the deliverable set, and normalise. If Agency A includes research, accessibility audit and a support window, and Agency B does not, add B's cost for those items before you compare. Most bid gaps close considerably once you do this, and occasionally they invert.

Seniority mix. Ask for the ratio of senior to mid to junior on the engagement. Two seniors will usually outperform four juniors on an ambiguous enterprise problem, and they will consume less of your time doing it.

Ramp-up time. How long before the team is productive in your environment? An agency with genuine experience in your sector might be useful in week one. One learning your domain from scratch might take six weeks, and you are paying for all of them.

Decision velocity. Ask how they handle a blocked decision. The best enterprise agencies have a documented process for moving forward under uncertainty and revisiting later. The rest wait, and bill you for waiting.

Governance absorption. Can they run your steering group, produce your board slides and handle your security team without escalating every friction point to you? In a large organisation this capability is worth more than a lower rate, because the alternative cost lands on your own headcount.

What happens at week nine. Every project of this size has a bad week around the two-thirds mark. Ask each agency to describe a project that went wrong and what they did. The ones that answer specifically, with a named problem and a named consequence, are telling you the truth. The ones that describe a challenge that turned into an opportunity are telling you a story. [internal link: best digital product agencies for enterprise clients → /insights/best-digital-product-agencies-for-enterprise-clients]

Reference calls with the right question. Do not ask referees whether they were happy. Ask what the final invoice was against the original estimate, and why it differed. That one question is worth an entire reference call.

Setting your budget before you go to market

Work backwards. Decide what decision this MVP needs to unlock, and how much that decision is worth. If a successful MVP unlocks a £4m platform programme, spending £180,000 to de-risk it is straightforward arithmetic. If it validates a £300,000 internal efficiency saving, a £40,000 discovery and prototype is the right first commitment and anything larger is premature.

Then set a band rather than a number, put the band in the RFP, and ask each agency to propose what they would do inside it. Publishing your budget does not cost you leverage, it saves you three rounds of re-scoping. Agencies that price to your budget regardless of scope will reveal themselves quickly. Agencies that come back and say your budget buys phase one but not phase two, and here is why, are the ones worth talking to.

Go back to those four quotes at the top: £38,000, £110,000, £240,000 and a request for a call. With a tight brief, six named variables and thirty-two questions answered in a comparable format, that spread usually collapses to something you can actually choose between, and the agency that asked for a call first is frequently the one that understood the problem best.
