September Reset: How to Get Your Business Admin and Finances Back on Track Before Year End
A practical, honest guide for female founders who want to finish the year feeling in control — not playing catch-up.
Can I ask you something?
Hand on heart — how does your business feel right now, at the start of September?
If the honest answer is "a bit behind" — you are in very good company.
September is the month that exposes what drifted over summer. The bookkeeping that didn't quite get done. The invoices that went out late, or not at all. The expenses that were never recorded. The admin that kept getting pushed to next week, and then the week after that.
And now here we are. The year is two thirds over. Q4 is almost here. And that quiet, low-level feeling that you need to get on top of things has become a little harder to ignore.
I want to help with that today.
Not with a lecture, and not with a complicated system you'll never use. Just a calm, practical reset — the things that genuinely make a difference between now and December.
First — give yourself a moment
Before we get into the practical stuff, I want to say something important.
If your admin and finances have slipped over summer, that is not a sign that you're bad at running a business. It's a sign that you're human. Summer is hard — you're trying to rest, trying to be present, trying to keep up with client work, and the back office quietly takes a back seat.
It happens to almost every solo female founder I speak to. The difference between the ones who feel in control by Christmas and the ones who don't isn't that the first group never let things slip. It's that they did something about it in September.
So — let's do something about it.
Step 1 — Get honest about where you actually are
Before you can reset, you need to know what you're resetting from. This sounds obvious, but a lot of business owners avoid this step because it feels uncomfortable. They'd rather not know exactly how far behind they are.
I want to gently encourage you to look anyway.
Spend 20 minutes this week doing a quick audit:
Invoicing: Are all your invoices from the last three months sent? Are any outstanding and overdue? Do you know exactly who owes you money and how much?
Bookkeeping: Are your income and expenses recorded up to date in your accounting software — or is there a backlog of transactions sitting there unrecorded? Roughly how many months are you behind?
Expenses: Have you been keeping track of your business expenses — software subscriptions, travel, phone, home office costs? Or have some slipped through without being recorded?
VAT (if applicable): When is your next VAT return due? Do you have a rough sense of what you owe?
Self-assessment: Your self-assessment tax return is due by 31st January. Do you have a clear picture of your income and allowable expenses for this tax year so far?
Write down the honest answers. You can't fix what you haven't faced.
Step 2 — Tackle the bookkeeping backlog first
If your bookkeeping is behind, this is where to start — because everything else (VAT, self-assessment prep, understanding your profit) depends on having clean, up-to-date records.
The good news is that even a small amount of focused time makes a significant dent.
Block out two hours this week. Open your bank statements and your accounting software side by side — whether that's FreeAgent, QuickBooks, Xero or even a spreadsheet — and start working through transactions chronologically.
Categorise each one as you go: income, business expense, personal. Don't try to do everything perfectly in one go. Just start.
A few things to remember as you do this:
You can claim a wide range of expenses against your tax bill — your business phone (or the business proportion of your personal phone), software subscriptions, stationery, postage, travel for business purposes, professional development, accountancy fees, and if you work from home, a proportion of your household costs. Record everything. If you're not sure whether something qualifies, note it down and look it up — don't just skip it.
Keep your receipts. HMRC can request them. A folder in Google Drive works well for capturing them as you go.
Step 3 — Chase your outstanding invoices
This one is uncomfortable for a lot of female founders. Chasing money feels awkward. It feels pushy. It feels like it might damage the relationship.
Here's the truth: a polite, professional payment reminder is completely normal business practice. Most late invoices are late simply because nobody followed up — not because the client intends not to pay.
Go through your outstanding invoices this week. For anything overdue by more than a week, send a simple, warm email:
"Hi [Name], I hope you're well. Just a gentle reminder that invoice [number] for [amount] was due on [date]. Please do let me know if you have any questions or if there's anything I can help with. Looking forward to hearing from you."
That's it. Friendly, professional, clear. Send it. Most people will pay within a day or two of being reminded.
Step 4 — Put your key dates in the diary now
One of the main reasons year-end feels stressful is that deadlines arrive unexpectedly. The solution is simple — put them in your diary now, with a reminder two weeks before each one.
Here are the key dates for UK small businesses to have on your radar:
5th October 2026 — deadline to register for self-assessment if you're newly self-employed
31st October 2026 — deadline for paper self-assessment tax returns (most people file online, but worth knowing)
31st January 2027 — online self-assessment deadline AND payment deadline for any tax owed
VAT returns — if you're VAT registered, check your specific quarter end date. Returns are due one month and seven days after your VAT period ends.
Companies House — if you have a limited company, check your confirmation statement and annual accounts filing deadlines. Missing these results in automatic fines.
Put these in your calendar today. Future you will be very grateful.
Step 5 — Build one small habit that keeps you on track from here
The September reset is worth nothing if October looks the same as August.
The single most effective habit I'd suggest — and it genuinely takes ten minutes a week — is a Friday finance check-in.
Every Friday, before you close your laptop:
Look at what came into your business account this week
Look at what went out
Categorise any transactions you haven't already recorded
Check if any invoices need to be sent or chased
Ten minutes. Every Friday. That's it.
If you do this consistently from now until December, your year-end will feel completely different. You'll know where you stand. Nothing will have piled up.
And instead of spending January in a panic, you'll be ready.
A final thought
I know that for a lot of female founders, the financial admin side of the business is the part that feels most overwhelming. The part that gets pushed to last. The part that quietly causes the most anxiety.
I want to say clearly: you are completely capable of getting on top of this. It doesn't require an accountant. It doesn't require a complicated system. It requires a couple of hours of honest attention, a few simple habits, and the decision to stop letting it drift.
But I also want to say — if the list feels too long, the backlog too big, or the whole thing too much to tackle alongside actually running your business — that is exactly what I am here for.
