How to Choose an Accountant for Your Startup
Startups do not need a corporate finance department on day one. They do need an accountant who understands incomplete records, fast change, and the difference between keeping HMRC happy and giving founders numbers they can use.
Introduction
This is a buyer’s guide: when to hire, what to compare, and which warning signs to take seriously. It is not a substitute for DepoTax’s startup service page, which sets out how we work with new businesses in practice.
Use the checklist at the end when you speak to more than one firm. The cheapest quote is rarely the full cost if bookkeeping, payroll and tax are extras.
Why startups have different accounting requirements
A settled high-street company often needs a clean year-end and a VAT return. A startup also needs a chart of accounts that will still make sense after hiring, a way to separate founder spending from company spending, and reporting that can support a grant, loan or investment conversation.
Software alone does not do that. Someone has to design the process, close the books, and tell you when the picture is not reliable.
When a founder should hire an accountant
Hire before you mix personal and company money at scale, before you take on staff, and before you sign for VAT or a funding round. If you have already incorporated and are issuing invoices, you are past the point where “we will sort the books later” is cheap.
A formation agent is not an accountant. Company formation creates the legal entity; it does not set up bookkeeping, PAYE or a tax timetable.
Business structure
Sole trader and limited company are the usual starting choices. Structure affects liability, how you pay yourself, and which returns you file. An accountant should explain the admin and tax consequences in your circumstances, not sell a company as the default.
If you already have a company because a platform or investor expected one, the accountant’s job is to make the company work: bank account, bookkeeping, payroll and records from the first transaction.
Bookkeeping setup and separating personal and business finances
Open a business bank account and run the company through it. Personal cards and cash “for now” create director loan and VAT problems that cost more to unwind than the convenience was worth.
Bookkeeping should be monthly, in software you will actually use, with bank feeds reconciled. Receipts need a home: a photo workflow is enough if it is consistent.
Payroll, VAT and Corporation Tax
Payroll starts when you pay staff or put a founder on a salary. PAYE has real-time reporting duties. Do not run “informal wages” through the bank and hope year-end will tidy them.
VAT registration can be required or voluntary depending on turnover and the type of supplies. Thresholds and schemes follow current HMRC rules, so the accountant should check the live position rather than a remembered figure.
A limited company will need accounts and a Corporation Tax return. Even if the first year is quiet, the timetable still runs from the accounting period.
Cash-flow forecasting and management reporting
Founders often know the bank balance and not the runway. A simple forecast of receipts, wages, tax, software and contracted costs is more valuable than a glossy model nobody updates.
Management accounts, even a short pack, tell you whether the business is becoming more efficient or only busier. Investors will eventually ask for this; it is easier if the habit already exists.
Accounting software
Choose software that your accountant will support, that banks can feed, and that can grow into payroll and inventory if needed. Popular cloud packages are fine for most startups. The failure mode is unused subscriptions and a spreadsheet that becomes the real system.
Ask who sets up the chart of accounts. A generic template that dumps everything into “general expenses” will not help you later.
Preparing for investment
Investors usually want a clean cap table story, current management information, a view of cash, and evidence that PAYE, VAT and Companies House filings are not a mess. They may also want forecasts that tie back to actuals.
You do not need a CFO at pre-seed. You do need books that an outsider can follow, and an accountant who can produce a pack without a two-month reconstruction.
Scaling accounting processes
As headcount grows, add approval for spending, a monthly close date, and a named person who owns receipts. The accountant can design this; they cannot chase every founder Slack message forever.
If you are adding entities, overseas contractors or equity schemes, say so early. Those are process changes, not year-end footnotes.
Warning signs when choosing an accountant
- A fee that only covers “accounts and CT600”, with every question billed extra
- No named person, and replies that take weeks in quiet periods
- No interest in how you take money out of the company
- No cloud software, or refusal to work in the tools you already use
- Advice copied from another startup without looking at your records
- Pressure to incorporate, claim reliefs, or change structure without explaining eligibility
- You cannot explain, after the pitch, who files what and when
Questions founders should ask
- What is included in the monthly fee, and what is billed separately?
- Who is my day-to-day contact, and what is a realistic response time?
- Will you set up the bookkeeping, or only collect a year-end folder?
- How do you handle payroll, VAT and director pay together?
- Can you produce management information for a lender or investor?
- Have you worked with companies at our stage, not only mature SMEs?
- What does the first 90 days of onboarding look like?
Fixed fees vs hourly fees
Fixed fees work when the scope is clear: bookkeeping, payroll for a stated headcount, VAT, accounts and a defined number of review calls. Hourly fees suit one-off projects, reconstructions and due diligence packs.
Ask what happens when you hire three people or add a marketplace. A good fixed-fee letter explains the trigger for a new price. An open-ended hourly arrangement without a budget is how startups overspend on admin.
Online vs traditional accountants, and responsiveness
Online-only firms can be efficient if the portal is used and someone still reviews the numbers. Traditional firms can be excellent if they are not stuck in annual paper. The test is responsiveness and quality of the close, not the office wallpaper.
Startups move weekly. If you cannot get an answer on payroll or VAT before a launch date, the firm is the wrong fit, however established it looks.
Understanding startup growth
Your accountant should be comfortable with messy early revenue, founder salaries that change, and the possibility that next year’s model is different. They should also be willing to say when the books are not yet good enough for a raise.
Growth without controls is how VAT, PAYE and cash sneak up on a team that thought it was “just focusing on product”.
Checklist for comparing startup accountants
- Written scope: bookkeeping, payroll, VAT, accounts, Corporation Tax, support channel
- Onboarding plan and software ownership
- Monthly close timetable
- Named contact and response standard
- Price change rules when headcount or entities grow
- Ability to produce a simple board or investor pack
- Clear boundary between compliance work and extra advisory
- References or examples at a similar stage (without confidential detail)
How DepoTax works with founders
DepoTax supports startups with setup, bookkeeping and tax as the company begins to trade, then management reporting as the numbers start to matter to other people. If you are comparing firms, read the startup service overview and then ask for a scope that matches your current stage, not a generic company package.
Frequently asked questionsFAQ
When should a startup hire an accountant?
Before mixing personal and company money at scale, before hiring, and before VAT or a funding conversation. If you are already invoicing through a company, you should not wait until the first year end.
Is a formation agent the same as a startup accountant?
No. Formation creates the company. An accountant sets up bookkeeping, payroll, tax filings and a reporting rhythm. You may need both, but they are different services.
Are fixed fees better than hourly fees for a new company?
Fixed fees work when the scope is written down: bookkeeping, payroll headcount, VAT and accounts. Hourly fees suit clean-ups and one-off packs. Ask what happens to the price when you hire or add an entity.
What should be in a startup accountant’s proposal?
A named contact, software plan, monthly close timetable, a list of filings included, response times, and the trigger for extra fees. If that is missing, the cheap quote is incomplete.
Do startups need management accounts from day one?
Not always a full pack, but they do need bookkeeping that can produce one. As soon as cash, hiring or investors matter, a short monthly report is more useful than a bank balance.
How do I compare online accountants with a traditional firm?
Judge the close and the response time, not the office. Online tools help if someone still reviews the numbers. A traditional firm helps if it is not stuck in an annual paper cycle.
