11 Common Bookkeeping Mistakes (And the 5 That Matter Most for Craft Beverage Businesses)

When I started mapping out this article, my plan was simple: share the top five bookkeeping mistakes I see most often in the craft beverage industry. But once I started digging into what other platforms and bookkeeping blogs were saying, I realised something interesting.

Across the highest ranking articles, mostly from accounting software companies and general small business advisors, the same mistakes kept coming up. Some of them are just as relevant for distilleries, wineries, and breweries. Others miss the mark because they don’t reflect the realities of managing excise tax, seasonal sales, or stock production cycles.

So, instead of writing yet another generic “top five” list, I’ve brought together the most common bookkeeping mistakes being talked about online and added my own take. I’ll share how each mistake shows up in the craft beverage space and which ones I think matter most if you want to build a profitable, sustainable business.

Let’s dive in.

Mixing personal and business finances ⭐

This is one of the most common mistakes flagged across all the bookkeeping blogs I reviewed. And it’s one I still see regularly, especially in businesses that have grown quickly or started out as a side project.

Combining personal and business spending in the same bank account might feel convenient at first, but it quickly leads to confusion. It makes tracking cash flow harder, muddies your financial reports, and turns tax time into a guessing game. Most business owners I speak to can recall at least one moment where they paid for something business-related from their personal account, then spent hours later trying to remember what it was for and sort it out for tax.

For craft beverage businesses, it gets messy fast. You’re not just dealing with a few transactions here and there. There’s stock to buy, taxes to manage, and seasonal income that needs careful planning. If you can’t see what’s coming in and going out clearly, it’s hard to make good decisions.

One of the first things I help clients do is separate out their accounts. If you’re following Profit First, this becomes even more important. Each account has a purpose, and keeping them separate gives you instant visibility into where your money is going.

Falling behind on bookkeeping or only doing it at tax time ⭐

This one came up in nearly every article I reviewed, and for good reason. Delaying your bookkeeping doesn’t just mean a longer to-do list later on. It usually means you’re making decisions based on outdated or incomplete information.

In the craft beverage industry, where margins can quickly change and cash flow often follows seasonal patterns, this kind of delay can create real stress. If you’re not looking at your numbers regularly, you might not realise you’re underpricing a product, spending more on freight than you expected, or getting behind on payments to suppliers.

I’ve worked with clients who haven’t touched their books in six months and genuinely had no idea whether they were profitable. That’s not a criticism. It’s just the reality of running a busy production-based business. But it makes planning, forecasting, and even day-to-day decision making much harder than it needs to be.

It doesn’t have to be perfect, and you don’t need to check your books every day. But building a regular rhythm, whether weekly, fortnightly, or even monthly, helps you stay on top of things without it becoming overwhelming.

Misclassifying expenses ⭐

This one doesn’t get talked about as often, but it shows up in almost every set of books I review. It’s easy to do, especially if you’re using software like Xero or QuickBooks without a proper chart of accounts or a clear understanding of which costs belong where.

Misclassifications might not seem like a big deal, but they distort your reports. If stock purchases are going into general expenses, or freight is sitting in admin instead of cost of goods sold, you end up with inaccurate margins and skewed financials.

For craft beverage producers, this is especially important. You’re working with excise, packaging, storage, and a mix of direct and indirect costs. If those aren’t allocated correctly, your pricing decisions are likely to be off.

One client I worked with was relying on profit and loss reports that looked fine at a glance. But when I investigated further I found some packaging expenditure in a Profit and Loss account and some sitting in a Balance Sheet stock account. Freight In and Out was combined with Post, so we had production and sales costs combined with administration costs. Once we cleaned these up and provided clear instructions going forward, they could finally get some clarity and confidence in their numbers.

Getting this right doesn’t have to be complicated. It starts with having clear categories and making sure whoever is doing the books understands your business and what the purpose of each account is for.

Ignoring accounts receivable and payable

One of the most common issues I see isn’t just forgetting to follow up on invoices or plan for upcoming bills. It’s not matching them correctly, if at all. If you’re not recording which invoices have been paid or which bills have been paid, your reports will be inaccurate and potentially misleading.

I’ve worked with clients and discovered debtors on the debtor list who had already paid, and debtors who weren’t on the list at all, even though they hadn’t paid. The same thing often happens with supplier bills. Payments are made, but the system shows them as still owing, or bills are missed entirely because they were never recorded properly.

In the craft beverage space, this gets especially tricky when you’re dealing with customers who deduct rebates and other charges from their payments. If these aren’t being tracked accurately, it becomes nearly impossible to plan your cash flow.

That doesn’t mean you need to do a full reconciliation every day. But getting into the habit of regularly matching payments to open invoices and bills gives you a clearer picture of where you really stand. And it’s a task that’s easy to automate or outsource with the right setup.

Not reconciling your accounts regularly

This is one of those tasks that feels small but has a big impact. If your accounts aren’t reconciled, then you can’t rely on the reports in your accounting software. That includes your profit and loss, balance sheet, aged receivables, and even your tax figures.

Reconciling simply means checking that the transactions in your accounting system match what actually happened in your bank accounts. If a payment came in, it should be matched to an invoice. If you paid a supplier, it should be marked against their bill. It is the only way to know your numbers are accurate.

If you are doing this yourself, even reconciling once a month can help you catch errors while the transactions are still fresh in your mind. If you are working with a bookkeeper, make sure it is part of their regular process and do not be afraid to ask questions if the numbers do not look right.

Doing your own bookkeeping without enough knowledge ⭐

This mistake came up across most of the articles I reviewed, especially in early stage craft beverage businesses. DIY bookkeeping often starts out as a cost saving measure, but over time it can cost far more than it saves. If you’re not sure whether it’s worth outsourcing yet, you can use my DIY Bookkeeping Cost Calculator to see what it’s really costing you in time and missed opportunities.

If you don’t have the right knowledge, it’s easy to miss tax obligations, miscode transactions, or build reports that look fine on the surface but don’t reflect reality. And when your margins are tight or seasonal, bad data leads to bad decisions. It is still the case that bad data leads to bad decisions.

I covered this in more detail in The real cost of DIY bookkeeping for distilleries, wineries, and breweries, but the key takeaway is this: doing your own books without understanding your numbers puts your business at risk. Not just from a compliance perspective, but from a profitability one.

It’s not just about saving time (though that’s a big factor). It’s about having confidence in your numbers, so you can plan, price, and invest with clarity. And that only happens when your bookkeeping system works for the kind of business you’re actually running.

Not keeping proper records or receipts

This might seem like a small admin task, but it can cause bigger problems than you’d expect. If you’re not keeping clear records of your purchases, it makes things harder at tax time, during reconciliations, or when reviewing costs and margins.

In the craft beverage industry, it’s unusual not to have multiple suppliers for packaging, ingredients, freight, and contract services. If you can’t easily access those bills or receipts, it becomes difficult to verify what you’ve spent and what was actually delivered. It also makes it harder to challenge incorrect charges or spot cost increases over time.

Most accounting platforms now allow you to attach receipts or bills directly to transactions, which makes life much easier if you ever need to look something up later. If you’re working with a bookkeeper, even something as simple as a shared folder or a weekly email check-in can help ensure nothing slips through the cracks.

This is one of those small habits that builds confidence in your numbers over time. It’s not about perfection, just consistency.

Failing to track small transactions or cash payments

It’s easy to focus on the big bills and overlook the small, day-to-day spending, but those smaller transactions add up quickly. If they’re not being captured in your accounting system, your reports will be incomplete and your margins may look better than they really are.

In a craft beverage business, this often includes purchases made with personal funds, petty cash tin spending, or expenses covered using event cash sales. These might be for on-the-go ingredient or packaging top ups, event supplies, or cellar door expenses. They’re often left unrecorded until long after the fact, if at all. In fact, I was discussing this issue with a distillery just two weeks ago. They were finding it hard to reconcile the event cash count with the sales information.

While no system will catch everything, it’s worth building a simple process for capturing these smaller spends. That might mean snapping a photo of the receipt and emailing it to your bookkeeper, keeping a shared spreadsheet for ad hoc purchases, or using accounting software with mobile functionality.

Every dollar you don’t record is a gap in your financial picture, and leads to overpaying taxes, underestimating your true costs, and overestimating your profitability.

Not understanding cash flow or profitability ⭐

This might sound like a bigger picture business issue, but it often comes down to the bookkeeping. If your books aren’t up to date, your costs are misclassified, you’re not correctly capturing the costs of the products that you sell, or you’re not reconciling accounts regularly, then the financial reports you’re relying on to understand cash flow and profitability simply aren’t accurate.

I know a business that uses their profit and loss report as a primary decision making tool, but it’s fundamentally flawed because they count and adjust for stock once per year. That means the cost of goods sold is highly likely to be incorrect, and that in turn means calculating potential tax liabilities has a high degree of risk error. The owner doesn’t really know what they could earn from the business. Without reliable figures, it’s hard to know if you have a business (profitable) or an expensive hobby (not profitable).

This is also where a cash management system, like Profit First, helps shift the perspective. A profit and loss report is a lagging view of what’s already happened, and if the bookkeeping isn’t accurate, it’s not even a reliable one. Profit First gives you visibility over real money in real bank accounts, each with a specific purpose: profit, tax, owner’s pay, operating expenses. That means you’re not just looking backward at what you think happened. You’re making decisions based on actual cash and future expectations.

When the books are up to date and your allocations are working, you don’t have to guess. You can see where the money is, what it’s for, and whether your business is actually supporting your goals.

Not using cloud accounting software or backing up records

It still surprises me when I start working with a business relying on spreadsheets, or paper based systems to manage their books. They’re making things harder than they need to be. Manual processes are not only time consuming, but they increase the risk of errors, duplication, and data loss.

Cloud-based accounting software like Xero or QuickBooks gives you real-time access to your financial data, no matter where you are. It also integrates with other tools, makes reconciliation easier, and allows your bookkeeper or accountant to work with you more efficiently.

We’ve all lost work on spreadsheets due to a laptop crash or a file that didn’t save properly.

Cloud systems also make recordkeeping easier. Things like uploading receipts, creating rules for recurring transactions, and connecting to your bank feed all reduce admin time and improve accuracy.

If you’re serious about growing a profitable business, this is one of the first systems to get right.

Not using inventory management software

If you’re running a distillery, winery, or brewery and you’re not managing stock, or managing stock manually, you’re probably missing key information that affects your margins, pricing, and cash flow. Without a proper inventory management system, it’s hard to know what stock you have, what it’s worth, and how much it’s actually costing you to produce each item.

This is particularly important in craft beverage production, where you’re dealing with batching, ageing, packaging variations, and seasonal demand. I’ve worked with businesses that had significant money tied up in raw materials and finished goods, but no clear way of tracking where it was sitting or how it flowed through into their financial reports.

Inventory and bookkeeping are closely linked. If your stock values aren’t accurate, your cost of goods sold and profit margins won’t be either. That means your pricing could be off, and your decisions around production and purchasing may be based on the wrong data.

If you’re not sure where to start, I’ve written more about how to choose the right inventory management software for your business, including what to look for and how to avoid common mistakes. If you’re running a distillery, you might also find this list of distillery management software options useful when comparing features.

Final Thoughts

Bookkeeping mistakes might seem small in the moment, but they build up over time and can have a big impact on cash flow, compliance, and profitability. The five I’ve highlighted as most critical are mixing personal and business finances, falling behind on bookkeeping, misclassifying expenses, doing your own bookkeeping, and not understanding cash flow or profitability. These are the ones I see most often in craft beverage businesses.

The good news is that each of these issues can be fixed. Whether it’s improving your systems, bringing in the right support, or simply reviewing your numbers more regularly, small changes can make a meaningful difference.

Clean, consistent bookkeeping gives you a clear view of how your business is performing. And from there, it becomes a lot easier to plan, grow, and make confident decisions.
