Production seat
Bookkeeping and VAT, payroll and admin, or marketing.
Muckin gives UK accountancy practices a named person’s month on their production work, from the Pretoria team of Buzz Accounting, with the accounts and tax work signed off by Buzz Accounting’s own UK practice. Chivvy built the brand, the site, the calculator and the portal the practices work in.






A practice signs in at app.muckin.co.uk, picks the client and the type of job, and drops the papers into a checklist with an upload slot for each one. The turnaround clock starts when the pack is complete and pauses while the team waits for an answer.
The dashboard shows the hours used against the seat this month, what is due this week, jobs by stage and everything that has moved lately.
Screens from the live portal with a demo practice, so the client names are made up.
Accounts work cannot reach Delivered until it has passed UK review, and the preparer and the reviewer are always different people. A practice approves the job with a rating, or sends it back with its reasons.


A cut-down copy of the capacity calculator on muckin.co.uk. Put in rough yearly numbers and it turns them into hours a month and the seats that fit.
Uses the same benchmarks as the full calculator: 5 hours a year-end job, 2 hours a self assessment return, 3 hours a bookkeeping client a month and 15 minutes an employee a month. Every seat after the first is 10% off. The UK figure uses salaries of £36,000 for accounts and £30,000 for other roles, times 1.35 for employer costs. Prices exclude VAT.
A seat is one person in one role for a set number of hours a month. The fee is fixed, billing is rolling monthly with one month’s notice, and every seat after the first is 10% off.
Bookkeeping and VAT, payroll and admin, or marketing.
Year-end accounts, corporation tax, self assessment and management accounts.
A qualified accountant at reviewer level, for complex work or review.
A short British verb for joining in with the hard part of a job, a wordmark with a yellow full stop, and copy written around the hours a practice gets back.
Services, pricing, guides, articles and side-by-side comparisons, all generated from one build script, with a new guide written and published every Tuesday.
A practice puts in its client numbers and gets hours a month, the seats that fit and the cost against hiring the same hours in the UK.
Every practice gets a login to send a job with its papers, follow it through six stages, answer queries in one list and watch the hours on its seat.
A six-digit code emailed at each sign-in, three levels of access for admins, members and partners, and files kept in private storage behind short-lived links.
Xero and FreeAgent connect from inside the portal, so a practice approves the link on their own sign-in screen and its client list arrives without retyping.
Muckin is a trading style of Buzz Accounting. The about page names the practice and every specialist brand it runs, so a practice choosing a team can see who is doing the work.
