Bookkeeping habits that quietly drain money from small businesses every year.

None of these are huge, obvious mistakes — which is exactly why they’re so dangerous. They build up over time, and before you know it, they’re costing you thousands.

>> Blurring the line between personal and business spending

This is one of the biggest issues business owners face. If everything runs through the same account, it becomes almost impossible to track what’s really going on. Separate accounts aren’t optional — they’re essential.

>> Skipping monthly reconciliations

Small discrepancies don’t stay small for long. A minor error early in the year can snowball into a much bigger problem if it’s not caught quickly.

>> Categorising expenses incorrectly

When expenses are recorded in the wrong place, your reports stop reflecting reality. That can lead to poor decisions and potential issues when it comes to tax time.

>> Overlooking unpaid invoices

Money that hasn’t been collected isn’t helping your business. Without proper tracking, it’s easy for outstanding payments to slip through the cracks.

>> Failing to keep proper records

Receipts and documentation matter. Without them, you risk losing out on legitimate deductions if you’re ever asked to prove your expenses.

>> Leaving everything until year-end

Trying to organise a year’s worth of finances in one go is stressful and often expensive. Keeping things up to date each month avoids the last-minute panic. If you give a years worth of records to your accountant to do, they will charge you 3x the rate of a bookkeeper to categorise the transactions and reconcile the bank.

>> Not reviewing your numbers regularly

Your Profit & Loss report tells the story of your business. If you’re not checking it consistently, you’re making decisions without the full picture.

If any of this sounds familiar, you’re not alone — but it is fixable.

I help small business owners stay on top of their finances with simple, stress-free bookkeeping. No more guesswork, no more scrambling at year-end — just clear, accurate numbers you can actually rely on.

If you’re ready to take control of your finances (and stop money slipping through the cracks), feel free to message me and let’s chat about how I can help

MTD for ITSA, are you ready?

Timeline:
April 26 - Landlords and Sole Traders with a gross income of £50k or above
April 27 - Gross income above £30k
April 28 - Gross income above £20k

Reporting due dates:
One month plus 7 days after the period end if you are using calendar months. One month plus 2 days after the period end if you are using tax months.
Period end - 30th June due 7th Aug
Period end - 5th July due 7th Aug

Did you know?
- If your software doesn't allow it, you will have to submit separate updates for each income stream.
- You can go limited if you want to avoid it however, you need to call HMRC and evidence this with your incorporation certificate.
- You have to use compatible software or, if you still use excel or old fashioned cashbooks, you will need to use bridging software.
- The quarterly updates don't take into account expenses or any allowances you may claim on your final tax return.
- You still have to submit your final tax return. So you will have to report to HMRC 5 times for 1 tax year!
- There are some exemptions for signing up.
- You can defer for a period of time depending on any allowances or reliefs you claim.
- HMRC's key focus sectors are construction and real estate.
- The gross income is for trade and property income only, it does not include any PAYE, pension or other income.
- If you have separate trade or property income streams, the gross income is these combined.

I will ask again, are you ready for MTD for ITSA? If you don't think you are, or don't feel ready, I can support you through signing up, getting ready, any software training to meet the guidelines or just holding your hand through the first quarter. Feel free to reach out if you want some guidance.

Time for a little introduction…

Hi, I’m Catherine. Recently took the leap and gone self employed after working in an accountancy practice for 8 years.

I’m AAT L3 qualified and part way through my L4 (had to take a break because I had a child and nights of sleep were not in my favour). I am an AAT licensed bookkeeper, ICO registered & AML supervised.

I still do sub contracting work for my previous employer so have several chartered accountants and tax advisors on hand. I am a registered agent with HMRC, experienced with sage, certified Xero and QuickBooks advisor and have lots of experience in bookkeeping, VAT, payroll and accounts prep. I am also here to help for MTD for income tax if that’s what you need (I will add more info on this before the deadline for you).

My goal for my clients is to reduce that annual accountancy bill that everyone dreads and build a relationship that is trusting and lasting. So, if you want to chat about how I can help you, feel free to reach out.
