What does an accountant actually do for a small company?
At Lumi, six things — and every one of them is done by the same Chartered Accountant, not a rotating team. Everything below is included in a fixed monthly fee (with Xero), so a question never turns into an invoice.

Year-end accounts & corporation tax
Statutory accounts and the CT600 prepared, reviewed and filed on time by a Chartered Accountant — every allowance claimed, no year-end bill shock.
Included in every package →Self Assessment
Personal tax returns for directors, sole traders and landlords, filed accurately and early so January is never a panic.
Director's return included →VAT returns & registration
Registration, the right scheme, MTD quarterly returns and the cash-flow options most owners miss.
Included from Core →Xero bookkeeping
Reconciled, coded and MTD-ready records kept current, so your numbers are always real and year-end is quick.
From 50 transactions on Lite →Payroll & pensions
PAYE, RTI filed on or before payday, auto-enrolment, statutory pay and payslips — from a single director to a growing team.
Director's payroll included →CIS returns
Subcontractor verification, monthly CIS returns, deduction statements and rebate claims for contractors and subbies.
Built into construction packages →Specialist accountants for hospitality and construction businesses
Some sectors carry compliance the standard packages don't cover. These pages explain what we watch for and what it costs. Not in either sector? Most of our clients aren't — the standard packages cover every other kind of business.
Hospitality
Pubs, cafés, restaurants, bars and hotels — VAT on food and drink, tronc and tips, rota-driven payroll, seasonal cash flow. From £220/month.
Sector page →Construction & trades
CIS, the VAT domestic reverse charge, retentions and job costing for contractors and subcontractors. From £275/month.
Sector page →Add-ons and one-off work, quoted before we start
Company formation, VAT and PAYE registration, management accounts, cash-flow forecasts, business plans, overseas VAT, due diligence and strategy meetings are all available alongside a package. Anything outside your monthly fee is quoted first and never invoiced afterwards without agreement — see what the monthly fee doesn't cover.

How does working with Lumi actually work?
Four steps, and you do very little of the work. A free 30-minute call, a fixed monthly fee in writing, a handover from your old accountant that I run, and then a monthly rhythm of bookkeeping, VAT, payroll and a plain-English update on where you stand. Year-end accounts and tax come out of that routine rather than being a scramble.
- A free 30-minute call. You tell me about the business; I tell you what you actually need and what it costs. If you don't need an accountant yet, I'll say so.
- A fixed fee, in writing. One monthly figure that covers the package you've chosen, Xero included. Anything outside it is quoted before we start, never invoiced after.
- I run the handover. Professional clearance from your old accountant, the records collected, Xero set up or tidied, and a start date agreed. Most switches take about two weeks and you do almost nothing.
- Then it's monthly. Bookkeeping reconciled, VAT and payroll filed, and a short update on what the numbers say. Year-end accounts and corporation tax fall out of that, on time, with no surprises.
