Online accountants vs the high street
Most local firms near Castelnau quote low, bill by the hour and reserve the right to charge for every phone call. We built the opposite: written fixed fees agreed up front, unlimited questions inside the price, and a fully online workflow — no premises anywhere, so no premises priced into your fee in Castelnau.
There's no office to fund in Castelnau and no office to visit: records travel through our secure portal or WhatsApp, approvals happen on your phone, and filings go to HMRC and Companies House electronically. You get the same qualified work — minus the overheads, the travel and the surprises on the invoice.

Castelnau startup accountants FAQs
What is SEIS/EIS advance assurance and do I need it?
It's HMRC's provisional confirmation that investment in your company qualifies for SEIS/EIS tax relief — and most angels won't invest without it. We prepare and submit the application, including the business plan framing HMRC expects.
We haven't made any money yet — do we still need an accountant?
Your filing duties start at incorporation, revenue or not — accounts, confirmation statements, corporation tax registration. Getting software and structure right from day one is also dramatically cheaper than untangling a year of DIY records later.
Can you handle share options and multiple share classes?
Yes — growth shares, EMI options and investor share classes are common startup territory. We'll flag when you need a specialist valuation and handle the accounting and filings around it.
Do I need to visit an office in Castelnau?
No — there's nothing to visit and nothing to print. We're an online firm: records go through our secure portal or WhatsApp, and everything is filed electronically. It works the same whether you're in Castelnau or anywhere else in South West London.
I searched "startup accounting near me" — is this service really local to Castelnau?
Castelnau is fully covered, yes. The work is done online, which in practice means more local than an office: same-day replies instead of appointment slots, and the same published fixed fee whether you're in Castelnau town centre or the edge of South West London. If you'd rather talk it through first, WhatsApp us — a real person answers.
Who will actually handle my startup accounting?
Bohzo Accountants — a trading name of Bohzo Ltd, a registered UK company (No. 15031604). You get a named contact, a fixed fee in writing, and nothing is filed until you've reviewed and approved it.
How do your fixed fees work?
You tell us your situation, we quote one fixed price in writing before any work starts, and that price never changes mid-job. If your case is unusually complex we'll say so up front and agree a different fixed price — but the fee is always agreed before we begin, never after.
Things worth knowing before your next filing
The honest answer changes with your profits. At lower profits, sole trader simplicity usually wins; as profits grow, a limited company's mix of salary and dividends, corporation tax rates and liability protection starts earning its extra admin. We run the actual numbers before recommending either.
UK residential property sales have their own regime: report and pay within 60 days of completion, separately from Self Assessment. Other gains report annually. Mixing up the two timetables is a common and expensive mistake.
Some businesses register for VAT before they must — reclaiming input VAT can be worth it if your customers are VAT-registered themselves. Others should stay below deliberately. It's a real decision with real numbers, not a formality.
Since Section 24, individual landlords can't deduct mortgage interest as an expense — it's a 20% tax credit instead, which pushes some higher-rate landlords into surprising bills. Whether to hold property personally or through a company is now a genuine question with genuine trade-offs.
If your last Self Assessment bill was over £1,000, HMRC usually asks for next year's tax in advance — half on 31 January, half on 31 July. It's the number-one cause of "why is my bill double?" calls, and it's manageable: if your income has dropped, the payments can be reduced with a claim.
Every tax bill is predictable months in advance — which makes tax the most plannable cost a business has. A separate tax savings account, fed a fixed percentage of every sale, converts January from a crisis into a transfer.
People stay with the wrong accountant for years because switching feels disruptive. In practice the profession has a standard handover process — clearance letters, copies of prior returns and working papers — and the new firm drives it, not you.
Register with HMRC by the 5 October after your first tax year of trading, open a separate business account, and put a fixed slice of every payment aside for tax. Do those three things and your first January will be boring — the good kind.
