Bookkeeping for Small Business: Industry-Specific Guide

Specialised bookkeeping for ecommerce, restaurants, construction, real estate, startups and self-employed. Practical tips for UK business owners.

Let’s be honest – bookkeeping isn’t the same for every business. A cafe has different needs from a builder. An Amazon seller’s accounts look nothing like a property investor’s. We’ve worked with hundreds of UK small businesses across different sectors, and the one thing we’ve learned is that one‑size‑fits‑all bookkeeping rarely works. This guide covers what each industry needs to think about when it comes to keeping the books straight.

bookkeeping for small business

Good bookkeeping for any small business means knowing what’s coming in, what’s going out, and what you owe HMRC. But the details vary. A service‑based business needs to track time and invoices. A product‑based business needs to manage stock. A landlord needs to keep property‑by‑property records. The fundamentals are the same, but the focus shifts depending on what you do .

For most small businesses, the goal is simple: keep the books tidy enough that you know where you stand, without spending hours on it. That means having a system that works for your specific situation, not trying to fit your business into a system designed for someone else .

What all small businesses need in common:

  • Accurate income and expense tracking
  • VAT returns filed on time (if you’re registered)
  • Bank reconciliation – making sure your records match the bank
  • Clear visibility of who owes you money
  • Records ready for your accountant at year end

As soon as you begin to examine individual industries, the disparities do become noticeable. We will go through some of the key ones.

ecommerce bookkeeping and amazon sellers

Operating an online store – Amazon, Etsy, Shopify, or a combination of all of them – introduces a new set of complexities that you simply do not encounter elsewhere. Several sales channels, fees that disappear before you can even get the money back, refunds that go in and out, and stock that could be in a warehouse somewhere. It’s a lot to keep straight .

The biggest headache for ecommerce sellers is usually transaction fees. Amazon, for example, takes a cut of each sale – sometimes 15% plus other charges. If you’re not tracking those separately, your revenue looks higher than it really is. We’ve seen sellers panic at tax time because they thought they’d made £100,000 when actually the net was much lower .

What ecommerce bookkeeping needs to cover:

  • Sales by channel: Amazon, eBay, your own website – you need to know which platform is making money and which isn’t
  • Fee tracking: Listing fees, fulfilment fees, advertising costs – all need to be recorded properly
  • Stock management: Cost of goods sold is a big part of your profitability. If you don’t know what you paid for your stock, you don’t know your true profit
  • Refunds and returns: These can get messy if you’re not on top of them
  • VAT on cross‑border sales: If you sell to Europe, VAT gets complicated quickly
A real example

One Amazon seller we worked with thought she was doing alright – turning over about £80,000 a year and guessing she was pocketing around £40,000. When we actually crunched the numbers, after fees, stock costs, and everything else, her real profit was £12,000. She’d been spending money that wasn’t really there. Once she could see the true picture, she tweaked her pricing and cut back on some slow-moving stock. Six months later, her profit had climbed to £24,000.

If you’re selling online, getting software that hooks straight into your platforms is a no‑brainer. Things like A2X or Link My Books pull all your Amazon and Shopify data into Xero or QuickBooks automatically. Saves a ton of manual work and means nothing gets missed .

restaurant bookkeeping services

Restaurants, cafes, takeaways – they’ve got their own flavour of bookkeeping challenges. Cash is still around, margins are famously tight, and stock is coming and going constantly. We’ve worked with quite a few hospitality businesses, and the common thread is usually cash handling and stock wastage .

Key areas for restaurant bookkeeping:

  • Cash sales vs card sales: Cards are easier to track, but cash still needs handling properly. If the till says one thing and the bank deposit says another, HMRC will notice
  • Stock and wastage: Food cost is usually your biggest expense. Without proper stock tracking, you won’t know if you’re over‑ordering, letting things go off, or losing margin somewhere
  • Supplier invoices: A typical restaurant deals with loads of suppliers – meat, veg, dry goods, drinks. Easy to lose track of invoices if you don’t have a system
  • Wages: Staff costs are another big one. Making sure PAYE is right and paid on time is non‑negotiable
  • Tips and tronc: Tips can get complicated, especially if you run a tronc scheme. It’s worth getting right from the start
What we see working

The hospitality businesses that do best with their books are usually the ones where the EPOS (the till system) talks to the accounting software. Sales flow through automatically, stock updates itself, and the bookkeeper can spot when margins are slipping or a supplier has quietly put their prices up before it becomes a problem.

construction bookkeeping services

If you’re in construction or the trades – builder, electrician, plumber, joiner – your bookkeeping is different from most. You’re out on sites, moving between jobs, and paperwork has a habit of piling up in the van. Then there’s the CIS scheme to deal with, which adds another layer .

What construction bookkeeping needs to handle:

  • CIS (Construction Industry Scheme): If you’re a contractor, you need to deduct tax from subcontractors and report it to HMRC every month. Get this wrong and you’ll hear about it quickly
  • Job costing: You need to know if each job actually made money. That means tracking materials, your own labour, and any subcontractors against each project
  • Materials and plant hire: Costs vary between suppliers. Good bookkeeping helps you see who’s giving you the best deal
  • Vehicle and equipment costs: Vans, tools, machinery – these are big investments. You need to track them properly for tax and to know if hiring would be cheaper
  • Invoicing and payment terms: Construction often has long payment cycles. Knowing who owes you what is essential for cash flow
A typical story

A builder we work with used to estimate his profit at the end of the year by looking at what was left in the bank. When we set up proper job costing, he realised some jobs were losing money. He was underquoting on bigger projects because he wasn’t accounting for all the labour. Now he knows exactly what each job costs, and his profit margin has gone from 12% to 22%.

For tradespeople, mobile apps are a game‑changer. You can raise invoices on site, snap photos of receipts, and track time against jobs from your phone. It means less paperwork and more time doing the work that pays .

real estate bookkeeping

If you’re a landlord or property investor, your bookkeeping needs are different again. You’re dealing with rental income, mortgage interest, maintenance costs, and potentially multiple properties. And if you’ve got a limited company for your property business, you’ve got corporation tax to think about too .

Key areas for real estate bookkeeping:

  • Property‑by‑property tracking: To know if a property is actually profitable, you need to track income and costs separately for each one
  • Mortgage interest: The rules have changed over the years. For individual landlords, you get a tax credit rather than a deduction. For limited companies, you can still deduct it. The bookkeeping needs to reflect which scenario applies
  • Repairs vs improvements: Repairs come off your income tax bill straight away. Improvements (like a new kitchen) are capital and affect your capital gains when you sell. Getting this right matters
  • Service charges and ground rent: If you’re in a leasehold property, these need tracking
  • VAT on property: Most residential property is exempt from VAT, but commercial property can be different. If you’re in commercial, it gets more complex

A note on incorporation: Many landlords are moving their properties into limited companies. The bookkeeping for a property company is different – you have corporation tax instead of income tax, and you need to think about director’s loans, dividends, and the tax implications of transferring properties across.

bookkeeping for startups and self employed

If you’re just starting out, or you’re self‑employed, your bookkeeping needs are simpler but just as important. You don’t have the complexity of stock or multiple properties, but you do have to get the basics right from day one. Poor records at the start lead to problems later .

What startups and self‑employed need to focus on:

  • Separate bank account: This is the number one rule. Mixing business and personal money makes everything harder. A separate account is free for most banks
  • Track everything: Even if you’re small, record every expense. The ones you forget add up. Use an app or a simple spreadsheet – just be consistent
  • Know your VAT position: If you’re likely to hit £90,000 turnover, you need to be ready. Good bookkeeping means you’ll see it coming
  • Set aside for tax: The biggest shock for new self‑employed people is the tax bill. Put 20–25% of your income aside from day one
  • Get software early: It’s much easier to start with a cloud system than to try to catch up later. FreeAgent, QuickBooks, and Xero all have starter plans that won’t break the bank
Making Tax Digital is coming

From April 2026, self‑employed people earning over £50,000 will need to start using MTD for Income Tax. That means quarterly updates to HMRC, not just an annual return. Getting your bookkeeping sorted now means you’ll be ready when the time comes.

For startups and self‑employed, the best advice is to keep it simple. Use software, keep your receipts, and don’t let things pile up. A few minutes a week saves hours of stress later .
