How to model a proposal software budget in the UK

What to take away

How vendors structure proposal software pricing

Almost every proposal and quoting tool on the market prices by user. You buy a number of seats, each seat belongs to a named person, and the monthly or annual fee follows from that number. A small sales team of five therefore pays roughly five times what a single user pays on the same tier.

Some vendors also meter usage. They may count documents sent, e-signature envelopes, or quoting transactions per month. When you compare two quotes, check whether the seat price includes an allowance and what happens once you exceed it.

A third model is the flat platform fee with a band of included users. This suits teams whose headcount is stable. It punishes nobody for sending more proposals, which matters if your sales cycle is short and volume is high.

Watch for minimum seat counts. Some tiers start at five or ten users, so a three-person team pays for seats nobody occupies. Others gate features by tier, which means the quoting module you actually need may sit above the entry price. Read the tier table, not the headline number.

There is no single industry price list, so the figures in this guide are illustrative examples, not market rates. To build a real budget, request written quotes from the proposal software vendors you are considering — for example Proposify, PandaDoc, Qwilr or Better Proposals — and verify what each tier includes. Published pricing pages give a starting point, but seat minimums, feature gates and usage allowances differ between them. Read the tier table, not the headline number.

Salesforce publishes pricing plans for its CRM products; those are context for a wider CRM contract, not a price benchmark for standalone proposal software. If a proposal tool connects to Salesforce, ask the relevant suppliers to itemise any separate integration costs.

The headline price is not the invoice

A quoted seat price is a starting point. The invoice usually differs, and the gap is where budgets go wrong.

What sits inside a typical annual bill

A standard contract for a UK buyer normally has four elements. The subscription covers the named seats for a fixed term, usually twelve months, with a discount for paying up front.

Setup or onboarding is a one-off charge, sometimes waived for small teams. Template and content build may be charged by the day. Integration work, if you connect the tool to a CRM or ERP, is quoted separately by the vendor or partner.

Beyond the contract, plan for internal time. Someone has to load your pricing rules, rebuild your proposal templates and train the team. That person is on your payroll either way, but the hours are real and they compete with other work.

Ask the vendor to state what is included for the term, what recurs and what expires. A template build might be a one-off, while an integration connector can carry an annual maintenance charge.

Ask for the quote split by line before you compare anything. A vendor who will not separate setup from subscription leaves you guessing at the renewal, when the one-off work is finished and the price stays put.

How inflation affects multi-year deals

Multi-year agreements often include an annual uplift clause. That clause matters more when inflation is moving. The Bank of England sets monetary policy to meet a 2% inflation target.

Its inflation and 2% target explainer is the reference point most finance teams use to challenge an uplift figure. If a vendor proposes a 5% annual increase, ask what it is based on.

For backward-looking context, the Office for National Statistics publishes the Consumer Price Index (CPI) and the Retail Price Index (RPI), which show how UK consumer and producer prices have actually moved. A finance director who has seen those series will not accept an uplift clause that ignores them. Ask the vendor to tie any annual increase to CPI or RPI and to cap it at a fixed percentage agreed in the contract.

VAT and other tax points for UK buyers

For standard-rated software subscriptions, the UK VAT rate is 20%. HMRC's VAT Notice 700, the main guide to the scope of VAT, together with the rates guidance on GOV.UK, sets out which categories apply; check them before signing rather than relying on a vendor's summary.

Standard-rated software subscriptions are the common case. Where a product bundles services, treatment can differ between components. The vendor should state the rate on the quote.

If you are not VAT-registered, the gross figure is your true cost. If you are registered and can reclaim VAT, the net figure hits your budget.

Check whether the vendor adds VAT at the point of invoice or collects it separately. Most software vendors invoice with VAT added. If the supplier is based outside the UK, ask your finance team how the invoice should be treated before you commit to a budget line.

Two smaller points. First, check the invoicing currency: a US vendor billing in dollars exposes you to exchange rate movement between quote and payment. Ask whether the quote is fixed in GBP or subject to the spot rate on the invoice date, and who bears the conversion cost. Second, check whether the price includes support and updates, or whether those are an add-on line.

A worked example for a 12-person sales team

Take a UK software company with twelve people who need to create quotes and proposals. The figures below are illustrative, labelled as such, and intended to show the shape of a budget rather than a market price.

VAT at the standard rate would be added to these figures if the buyer cannot reclaim it. At 20%, the year one gross cost would be £17,136. That is an illustrative calculation, not a quote.

Sensitivity matters more than precision here. At 20 seats the subscription line becomes £10,800 a year, and the year one total rises to roughly £18,600 ex VAT. Model two or three seat counts before you commit, because headcount is the assumption you control.

The point of the table is the ratio. Year one costs more than twice year two, because the one-off work lands in the first twelve months. A budget that only counts the subscription understates the first year by more than half.

The modelling procedure in five steps

If you want to rebuild this table with your own numbers, our proposal software budget template gives you the line items in a form you can hand to finance.

Hidden costs that appear after signature

Overages are the most common surprise. A seat-based contract with a document CAP can generate a charge in a busy quarter, and the rate per extra document is rarely on the pricing page. Ask for it in writing.

Support tiers are the second. Priority support, a named account manager or a faster response time may sit on a higher tier that the original quote did not include. If your team sells to tight deadlines, the standard tier's response time is worth checking before you assume it is fine.

Third, migration. Moving historical proposals, pricing tables and approval rules out of an old system takes time, and some vendors charge for it. Fourth, training: new joiners need onboarding, and if the vendor charges per session, that recurs every quarter.

Our proposal software hidden cost categories article lists the clauses to look for in a draft contract, including uplift wording and termination fees.

Comparing quotes on a like-for-like basis

Normalise everything to a single figure: total cost of ownership over three years, excluding VAT, with one-off and recurring costs shown separately. Then convert each quote to a per-seat per-month figure so the comparison is honest.

Check three things while you do it. Does the quote include the modules you actually need, or are quoting, e-signature and analytics priced separately? Is the seat count fixed for the term, or can you add and remove users mid-contract? What notice period applies at renewal?

It also helps to know what comparable software costs elsewhere in the stack. Forrester publishes budget planning guides for technology and marketing spend, which give a sense of how software budgets are typically split. Use them as context, not as a price list.

If you are still deciding who the tool is for, our buyer persona guide covers how to size the user group before you buy seats you do not need.

Building the business case

The commercial argument for proposal software rests on two numbers: time saved per proposal and the change in win rate. Both are measurable, and both are yours to measure.

Start with time: ask three salespeople to log how long they spend assembling a quote, from first draft to sent document. Multiply the average by the number of proposals sent each month, then by a loaded hourly rate.

Adoption is the assumption most likely to break the model. If half the team keeps quoting in spreadsheets, you capture half the time saving and pay the full licence. Set a review date at 90 days and check who is actually using it.

Then look at win rate. If a faster turnaround means quotes go out while the buyer is still engaged, conversion can improve. Treat any improvement as a hypothesis until your own data confirms it. Our nine steps to measure proposal software return on investment article sets out a simple model for combining both effects.

Write the assumptions down before you buy. A short spreadsheet covering hours, rate and proposal volume is enough to test a claim, and it survives a change of sponsor.

If your finance team asks where the underlying figures come from, the proposal software cost guide data and sources page lists the reference points behind this cluster.

Negotiating the contract

Timing is your main lever. Vendors with quarterly targets are more flexible near the end of a quarter. If you can wait, wait.

Term length is the second lever. A two-year commitment in exchange for a lower per-seat rate is a normal trade. Make sure the uplift clause is capped if you accept it.

Payment terms are the third. Annual up-front payment usually attracts a discount of a few per cent against monthly billing. If cash flow is tight, monthly is worth the premium.

Ask for a paid pilot rather than a discount. Three months with a fixed exit gives you evidence for the business case and costs far less than a twelve-month commitment you regret.

Finally, ask what happens if you reduce seats. A clause that lets you step down at renewal, rather than only up, protects you if the team shrinks.

Common questions

Is proposal software priced per user or per document?

Most commonly per user, per month, with an annual commitment. Some vendors add a document or e-signature allowance on top, and a few price by transaction volume instead. Check which model applies before comparing headline numbers.

Do I pay VAT on proposal software in the UK?

Usually yes. Standard-rated software subscriptions are generally subject to the 20% VAT rate. HMRC's VAT rates guidance on GOV.UK sets out the rates and exceptions. If you are VAT-registered and the software is used for business, you can normally reclaim VAT where the usual input-tax rules are met.

What is a realistic first-year budget for a small team?

For a team of around a dozen users, a first-year figure in the low tens of thousands of pounds including one-off setup and integration work is a reasonable planning assumption. Subscription alone would be a fraction of that, so budget for both.

How do I compare two quotes with different pricing models?

Convert both to a three-year total cost of ownership excluding VAT, then divide by seats and months to get a per-seat per-month figure. Show one-off and recurring costs on separate lines so the first-year premium is visible.
