Record keeping is easiest when it happens close to the work. Leave everything until much later and a fuel receipt, merchant purchase or bank payment loses the context that made it obvious at the time. A simple routine beats a heroic sorting session.
Separate business evidence from everyday clutter.
Decide where receipts, invoices and other business records go as soon as you receive them. A paper receipt left in a van door is not part of a system. Neither is an important supplier invoice buried among hundreds of unrelated emails.
You do not need an elaborate filing structure if the business is small. You need somewhere consistent enough that you or your accountant can find the evidence later. Keep records for the period required for your circumstances and ask your accountant if you are unsure what needs retaining.
Use a repeatable naming or filing habit for digital documents so another person can understand them. A folder full of files called scan001 and image7 still creates work later. Supplier, date and purpose are far more useful clues.
Deal with fading paper receipts promptly. Photograph or capture them using whatever record system suits your business and keep the original where required. The important point is that the evidence remains readable when you eventually need it.
Connect income to the work that produced it.
A bank transaction tells you money arrived. It does not always tell you which job it settled, whether it was a deposit or whether the customer still owes something. Record payments against the relevant invoices instead of relying on the bank statement to explain the business later.
Using payment tracking gives you a live operational reason to keep this information accurate as well. You can see what is still due while the records are also becoming more useful for accounts.
Do the same with deposits and part payments. A bank balance can look healthy while several jobs remain incomplete and some of that cash relates to future work. Knowing what a receipt represents gives you a clearer view of the business.
Refunds and credits need context too. Record why money went back to a customer or why a supplier issued a credit. Otherwise a later review can show a transaction without the explanation that made it sensible at the time.
Record business mileage while you remember it.
If you use your own vehicle for qualifying business journeys, keep the information needed to support the claim rather than trying to rebuild a year's travel from your diary. Record journeys consistently and distinguish business travel from ordinary commuting.
The treatment depends on how the vehicle and business are arranged, so use the method appropriate to your circumstances. For the approved mileage method, the mileage claim calculator can calculate a claim using the current rules without hard-coding changing rates into your own notes.
Keep enough journey detail to support the records your chosen method requires. A calendar can help reconstruct where you went, but relying on reconstruction creates unnecessary work and can miss journeys that never became formal appointments.
Be careful when the business owns or provides the vehicle because the appropriate treatment may differ from using your own vehicle. Your accountant can help you apply the right method rather than assuming one mileage approach fits every arrangement.
Keep job information with the job.
A merchant invoice can be easier to understand when you know which customer the materials were for. The same applies to parking, subcontracted work and unusual expenses. Where practical, connect costs and notes to the relevant work while the relationship is still obvious.
Maintaining job records with notes and history is useful for customers as well as accounts. Months later, you can see what happened at a property without trying to reconstruct it from photos, messages and memory.
If you buy materials for several jobs in one merchant visit, record enough detail to understand the split where it matters. Perfect allocation of every tiny consumable may not be practical, but significant job costs should not vanish into a general pile if you want to understand profitability.
Good job records also help explain unusual transactions. A second purchase of the same item may make sense because the first was faulty or the customer changed the scope. Without the job history, it can simply look like duplicate spending.
Give your accountant clean information, not archaeology.
An accountant can advise and prepare figures more effectively when the underlying records make sense. They should not have to guess why money moved or repeatedly ask you to identify transactions that you could have labelled when they happened.
Set a regular habit for checking missing receipts, unpaid invoices and unexplained transactions. A small amount of admin throughout the year is usually easier than stopping everything to rebuild the past just because a deadline is approaching.
Ask what format makes their work easiest. Your accountant may prefer records exported or categorised in a particular way. A short conversation early can prevent you maintaining a system that creates extra work for both of you.
Use the same records to manage the business between accounting deadlines. Knowing what is unpaid, what jobs made money and where costs are rising is valuable now, not merely when somebody prepares year-end figures. The useful test is whether the process still works on a busy week when several jobs, customers and decisions compete for attention. Write down the important information when it is fresh, keep the next action clear and review the result afterwards. A small trade business does not need layers of administration, but it does need enough structure that ordinary work does not depend on one person remembering everything.
