Why Good Bookkeeping Matters More Than Most Business Owners Think

Bookkeeping is one of those things that many business owners underestimate.

It can feel administrative.

Routine.

Something that can be tidied up later.

But the truth is that bookkeeping is the foundation of almost everything else in your accounts and tax affairs.

If the bookkeeping is wrong, then the figures built on top of it can also be wrong.

That can affect:

• Your annual accounts
• Your Corporation Tax return
• Your VAT returns
• Your management accounts
• Your cash flow
• Your understanding of how the business is actually performing

And ultimately, it can mean paying too much tax, too little tax, or ending up with questions and potentially penalties from HMRC.

That is why accurate, up-to-date bookkeeping matters.

Your Accounts Are Only as Good as the Bookkeeping Behind Them

A set of accounts does not appear from nowhere.

It is built from the underlying transactions in the business.

Sales invoices.

Purchase invoices.

Bank transactions.

Credit card transactions.

Payroll.

VAT.

If those records are incomplete or inaccurate, then the final accounts can also be incomplete or inaccurate.

The same applies to tax returns.

Your accountant can review the figures, ask questions and make adjustments, but if the underlying bookkeeping is poor, the whole process becomes more difficult and less reliable.

That is why I often say:

Good accounts start with good bookkeeping.

Poor Bookkeeping Can Mean Paying the Wrong Amount of Tax

If expenses are missing, you could end up paying too much tax.

If income has been recorded incorrectly, or costs have been duplicated, you could end up paying too little.

Either way, it creates a problem.

The same applies to VAT.

If purchase invoices are missing, you may fail to reclaim VAT that you are entitled to.

If sales are recorded incorrectly, your VAT return may be wrong.

Bookkeeping is not just about keeping the accountant happy.

It directly affects the tax position of the business.

The Problem With Lots of Supplier Invoices

This becomes particularly important in sectors such as hospitality and retail.

Many businesses in these sectors deal with the same suppliers over and over again.

You might have four or five key suppliers, but each supplier sends dozens of invoices every month.

That can create a surprisingly big bookkeeping problem.

Imagine one supplier sends you 70 invoices during the month.

You then make one payment covering all or most of those invoices.

If every invoice has been recorded correctly, the payment can be matched against them.

But what happens if two invoices are missing?

Suddenly the payment does not reconcile.

Someone then has to spend time finding out:

• Which invoices are missing?
• Was one recorded twice?
• Was there a credit note?
• Was part of the payment on account?
• Has an invoice simply never been received?

That can become a complete mess very quickly.

Ask Suppliers for Monthly Statements or Consolidated Billing

If you regularly receive lots of invoices from the same supplier, it is worth trying to simplify the process.

One option is to ask the supplier whether they can provide a monthly statement or consolidated billing arrangement.

Instead of dealing with dozens of individual transactions without any clear summary, you have something that helps you reconcile what has been purchased and what has been paid.

Even where individual VAT invoices are still required, a supplier statement can make the reconciliation process much easier.

The aim is simple:

You should be able to match what you have paid to what you have actually bought.

If you cannot do that, you start to lose control of the records.

Supplier Statements Are Extremely Useful

A supplier statement is one of the simplest bookkeeping controls a business can use.

It allows you to compare:

What the supplier says you owe

against

What your accounting records say you owe

If the two figures do not agree, something needs investigating.

That could be:

• A missing invoice
• A missing credit note
• A duplicate invoice
• A payment not allocated correctly
• An invoice posted to the wrong supplier
• A simple data-entry error

Finding these issues every month is much easier than discovering them at the year end.

Keep Copies of Every Invoice

This sounds obvious, but it causes problems surprisingly often.

If a business does not keep complete copies of its purchase invoices, accurate bookkeeping becomes much harder.

A payment appearing on the bank statement is not necessarily enough.

You need to know what the payment relates to.

You may also need the invoice to support the VAT treatment and the business expense.

Modern bookkeeping software makes this much easier than it used to be.

Invoices can usually be uploaded, emailed into the software or attached directly to transactions.

There is very little reason now for a business to have large numbers of unexplained payments with no supporting paperwork.

Reconcile Your Supplier Accounts Regularly

Do not wait until the year end.

If you have high-volume suppliers, reconcile them regularly.

For some businesses, that may mean monthly.

The process is straightforward:

1. Record all supplier invoices and credit notes.
2. Obtain the supplier statement.
3. Compare the statement with your accounting records.
4. Match payments against the relevant invoices.
5. Investigate any differences.

If you do this consistently, bookkeeping problems remain small.

If you leave it for six or twelve months, the same problem can become much harder to unravel.

Bookkeeping Is Also About Management Control

There is another reason this matters.

Bookkeeping is not just about producing accounts and tax returns.

It also helps you manage the business.

If your supplier balances are wrong, your debtor balances are wrong or your bank is not properly reconciled, how can you rely on the financial information you are looking at?

You might think you owe suppliers £50,000 when the real figure is £65,000.

You might think your margins are better than they really are because costs are missing.

You might think the business has more cash available than it actually does.

Once the bookkeeping becomes unreliable, management information becomes unreliable as well.

And that means business decisions start being made using the wrong numbers.

Good Bookkeeping Saves Time and Money

There is also a practical cost to poor bookkeeping.

If your accountant has to spend hours:

• Finding missing invoices
• Reconciling supplier balances
• Correcting duplicated transactions
• Investigating unexplained payments
• Repairing VAT errors

someone has to pay for that time.

Good bookkeeping makes the year-end process quicker.

It makes VAT returns easier.

It makes management accounts more useful.

And it usually reduces the amount of unnecessary clean-up work required.

The Bottom Line

Do not fall into the trap of thinking bookkeeping is unimportant.

It is the foundation on which your accounts, tax returns, VAT returns and management information are built.

If the bookkeeping is inaccurate, everything that follows can be inaccurate as well.

For businesses with lots of supplier invoices, particularly in hospitality and retail, make sure you have a proper process for:

• Recording every invoice
• Keeping supporting documents
• Obtaining supplier statements
• Matching payments correctly
• Reconciling supplier balances regularly

It may not be the most exciting part of running a business.

But meticulous bookkeeping gives you control over your finances and confidence that the numbers you are using are actually right.
