How accountants move to fixed-fee packages (and automate the onboarding that follows)

Moving to fixed-fee packages means replacing hourly billing and year-end invoices with a small menu of monthly plans, priced by client type and paid by direct debit. It smooths your income, removes the fee surprises that clients quietly resent, and turns every new engagement into a repeatable process rather than a bespoke negotiation. This article walks through how small UK accountancy and bookkeeping practices make the switch, and how to automate the onboarding chain that follows.

Most small practices already know this in theory. The gap is in the practical detail: what the packages should be, whether to put prices on the website, and how to stop every new client from becoming a two-week admin project. That is what follows.

Why hourly billing punishes you and your clients

Hourly billing has a design flaw that most accountants live with for years without naming it: it punishes efficiency. Invest in better software, tighter processes, and more experienced staff, and every job takes fewer hours, so you bill less for the same outcome. You are financially rewarded for being slow. Your best clients, the organised ones with clean records, subsidise the chaotic ones.

It is worse on the client side. Time-based fees billed in arrears mean the client never knows what the year will cost until the invoice lands. And here is the thing practices consistently underestimate: clients hate surprise bills far more than they hate high bills. A client who agreed £250 a month will pay it happily for years. The same client receiving an unexpected £3,000 invoice in June will question every line, delay payment, and start wondering what a competitor charges. The number is not the problem. The surprise is.

Hourly billing also makes clients afraid to call you. If every phone call might appear on an invoice, they stop asking questions, which means problems reach you late, when they are expensive to fix. A fixed monthly fee that includes "reasonable ad hoc queries" removes that fear, and paradoxically most clients use less of your time, not more, because they ask small questions early instead of saving up big ones.

Designing the package ladder

Resist the urge to build ten packages with a comparison grid of forty ticks. Three tiers, named by client type and outcome rather than by internal jargon, is almost always right. A typical ladder for a small practice looks like this:

Sole Trader. Self assessment, bookkeeping review, unlimited email support, an annual planning conversation. This is your entry tier, and its job is partly to be outgrown.

Limited Company Core. Statutory accounts, corporation tax, director's self assessment, confirmation statement, quarterly check-ins.

Limited Company Plus. Everything in Core, plus payroll, VAT returns, and management accounts or quarterly performance reviews.

Name them for the client, not for yourself. "Limited Company Plus" tells a director instantly which tier is theirs. "Gold" tells them nothing except that there is probably a Platinum you want to upsell them to.

Price each tier monthly, collected by direct debit through GoCardless or similar. Monthly pricing does three things at once: it matches how clients budget, it makes your fee comparable to their other subscriptions rather than to a lump sum, and it hands you recurring revenue (more on that below). When setting the numbers, price the outcome and the responsibility you carry, not the hours. If you are still anchoring to an internal hourly rate, our guide on how to price your services covers the shift from cost-plus thinking to value-based tiers in more depth.

Build in a fair-use boundary rather than a meter. "Includes reasonable day-to-day queries" is enough. The point of the package is that clients stop watching the clock; do not reintroduce the clock through the back door.

Publish your prices (almost nobody does, which is the point)

Search for accountants in any UK town and count how many show prices on their website. Typically it is close to none. The standard page says "every business is different, contact us for a tailored quote", which the visitor correctly translates as "it will be expensive and awkward to find out how expensive".

This is exactly the opportunity. When one local firm publishes a clear package ladder with monthly prices, it wins a disproportionate share of the comparison shoppers, because it is the only firm a prospect can evaluate without booking a call. Price-transparent firms also attract better-fit clients: the ones who read "Limited Company Core, from £150 a month" and get in touch have already accepted the price bracket, so your sales conversations become about fit rather than fee.

The fears are predictable and mostly unfounded. "Competitors will undercut us": they can already ask any client what you charge. "We will scare people off": the people scared off by your published price were going to be scared off by your quoted price anyway, after costing you an hour-long meeting. Use "from" pricing to keep room for complexity, list what each tier includes in plain English, and let the page do the qualifying. If your current site is a brochure that hides everything useful behind a contact form, it is worth reading why your website is losing you customers before you redesign the pricing page, and how to write website copy that converts when you draft it.

Automating the onboarding chain

Fixed fees fix the revenue model. Onboarding automation fixes the workload that success creates. Winning three new clients in a week should be good news, not a filing emergency.

Accountancy onboarding is unusually automatable because the steps are the same every time and most of them are documents and checks, not judgement. The chain looks like this:

1. Proposal accepted. The prospect picks a package and accepts, ideally online rather than by email ping-pong.
2. Engagement letter e-signed. Generated from a template with the package details merged in, signed electronically the same day.
3. AML and ID checks. Identity verification and anti-money-laundering screening run digitally; the client uploads ID from their phone.
4. Professional clearance letter. Sent to the outgoing accountant automatically, with a polite chaser if nothing comes back within a couple of weeks.
5. Direct debit mandate. Set up before any work starts, so the first month's fee collects on schedule.
6. Welcome email. "Here is what happens next", key dates, who to contact, and what you need from them, sent the moment the mandate completes.

Purpose-built tools exist for most of this: GoProposal and Ignition handle proposals, engagement letters, and payment collection in one flow, and pair with digital AML providers. For many small practices those are the sensible default. A lightweight custom flow (your website's package page feeding a form, an e-signature tool, and a few connected automations) can achieve the same result if you want it matched exactly to how you work; typical setups of that kind start from around £500. Either way, the principle is the one covered in how to automate your small business: automate the sequence, not just individual steps, so that completing one stage triggers the next without anyone remembering to do it.

The client-facing effect matters as much as the time saved. A new client who signs, verifies ID, sets up a direct debit, and receives a clear welcome email within forty-eight hours has just experienced your firm being organised. That first impression sets the tone for the whole engagement, and it is set by a machine while you were doing billable work. Track the whole pipeline in whatever CRM you run; if you do not run one, our plain-English guide to CRM for small businesses is the place to start.

Recurring revenue changes the shape of the practice

Ask a practice owner on time-based billing what January is like and you will get a grimace. Self assessment season concentrates work and cash into a brutal quarter, followed by months where revenue sags. It makes hiring risky (can you cover the salary in May?) and holidays guilt-ridden.

Fifty clients at an average of £200 a month is £10,000 arriving every month by direct debit, regardless of season. That predictability compounds into every other decision: you can hire ahead of demand rather than behind it, invest in software with confidence, and turn away poor-fit work because next month's revenue does not depend on saying yes to everything. It also transforms what the practice is worth. A buyer values contracted monthly recurring revenue far more highly than a history of one-off invoices, so the switch quietly builds your eventual exit even if that exit is a decade away.

Attract the niche you want, not "all businesses welcome"

The final piece is aiming this machine at the right clients. Most small firm websites say some version of "we act for businesses of all sizes across all sectors", which reads as "we have no particular expertise in your problem". A contractor searching for an accountant who understands IR35, or an ecommerce founder wrestling with marketplace VAT, will always choose the firm whose website speaks their language.

Pick one or two niches you already serve well (contractors, ecommerce, hospitality, construction) and build pages, packages, and articles for them specifically. "Ecommerce Accounting, from £220 a month, includes marketplace reconciliation and EU VAT" beats a generic tier for that client every time, and usually commands a higher fee because the expertise is visible. Niche pages also rank: far fewer firms compete for "accountant for Shopify sellers" than for "accountant near me". This is the same specialisation logic we apply when working with accountants and bookkeepers on their own positioning: the firms that name their client win them.

Where to start

Do not try to convert the whole client base overnight. Design the ladder, put it on the website, and sell every new client onto packages from today. Move existing clients across at their next renewal or year-end conversation, starting with the ones whose fees are most out of date. Within eighteen months most practices find the majority of the book has migrated, and January stops being something to survive.
