Monthly Management Accounts for Ecommerce: What Should They Tell You?

The orders are coming in, advertising is producing sales and the business has just had its best month. You should feel confident about placing the next stock order. Instead, you are looking at the bank balance and wondering whether you can afford it.

Your Shopify dashboard says one thing, the marketing agency is pleased with its results and Amazon has paid less into the bank than you expected. Somewhere between those numbers is the answer to whether the business is doing well.

This is where monthly management accounts should earn their place. They should explain what you have made, where the money has gone and what the business can sensibly do next. If the only outcome is a PDF confirming that sales went up, you have paid for information you probably already knew.

For a growing ecommerce brand, the useful discussion is much more specific. Can we increase advertising without sacrificing profit? Which products deserve the next stock investment? What tax is building up? Can the business fund a larger shipment and still pay everyone else?

A good monthly review gives you enough confidence to act, and enough warning to change course before a problem becomes expensive.

What should a useful monthly accounts pack contain?

I would expect a profit and loss account, a balance sheet and an explanation of the movement in cash. Alongside these, include the product and channel information that matters to your business, an updated forecast and a short explanation of what needs attention.

The profit and loss account shows the income and costs belonging to the period. The balance sheet shows what the business owns and owes at the month end. The cash analysis explains why the bank balance moved differently from profit. You need the connection between them to understand what is available to spend.

Compare the month with budget, the previous month and the same period last year where available. Include year-to-date results too. For a seasonal brand, December beating November may tell you far less than December falling short of its stock and marketing plan.

The practical test is whether your pack helps you make a decision. More pages do not automatically mean more useful accounts.

Are sales growing in a way that makes the business stronger?

Start with sales after discounts and refunds, excluding VAT. Include customer shipping income consistently where relevant. Then separate the effects of order numbers, average spend, pricing and product mix.

A business can increase revenue by finding more good customers. It can also do it by discounting heavily, selling more of its least profitable product or buying increasingly expensive orders through advertising. Those deserve different responses.

Your management accounts should reconcile the sales platforms to the bookkeeping and explain differences. A settlement is the amount paid after deductions and timing adjustments; it is not automatically the revenue earned. Money retained by a marketplace also needs accounting for, rather than disappearing because it has not reached the bank.

Platform definitions matter. Shopify’s sales reports include adjustments and have specific rules for taxes, shipping and order status. Do not assume that a dashboard total equals accounting turnover.

This is more than a bookkeeping nicety. If revenue is overstated or fees are missing, every margin and spending decision built on those figures starts in the wrong place.

What did the extra sales actually leave behind?

Consider this illustrative comparison. Both months use the same reporting layout. Sales are after discounts and refunds, excluding VAT; product costs are the landed costs of the units sold. Fulfilment, delivery, payment and marketplace fees are shown separately below gross profit so their effect is visible.

Monthly performancePrevious monthCurrent month
Net revenue£80,000£100,000
Landed cost of products sold£20,000£25,000
Gross profit£60,000£75,000
Fulfilment, delivery and selling fees£8,000£12,000
Paid advertising£10,000£18,000
Agency and creative costs£2,000£3,000
Contribution after these costs£40,000£42,000
Other operating overheads£16,000£17,000
Operating profit before finance costs and Corporation Tax£24,000£25,000
Operating profit margin30%25%

Sales increased by 25%. Operating profit increased by just over 4%. An extra £20,000 of revenue produced another £1,000 of operating profit, before considering what was needed to fund the growth.

The gross margin stayed at 75%, so the product purchasing margin has not deteriorated overall. The bigger changes are further down: fulfilment and selling fees took 12% of revenue instead of 10%, while paid advertising rose from 12.5% to 18%. Agency costs increased too.

That is the start of a useful conversation. Did the extra orders come through a more expensive marketplace? Did a fulfilment rate change? Was the advertising increase a planned customer-acquisition test, or did it simply become harder to generate each sale?

The current month still made more profit. Growth may be worth continuing. But the decision now rests on understanding the return, rather than celebrating the revenue and hoping the rest follows.

Which products and channels deserve more investment?

The overall margin can look healthy while individual products quietly consume cash. Ask for contribution by your main products, ranges and sales channels, using costs that genuinely relate to those sales.

For a product, that means its selling price after discounts and refunds, landed cost, relevant fulfilment and selling fees, and acquisition costs where they can reasonably be identified. Allocate shared costs consistently and make estimates visible. A precise-looking allocation is not necessarily an accurate one.

Compare Amazon and Shopify on that full basis. Amazon fees are visible, but a Shopify order still needs acquiring, processing and delivering. Moving sales to your own store does not make those costs vanish.

Also look at the total pounds contributed. A product with a 35% contribution margin on £5,000 of sales contributes £1,750. One with a 25% margin on £30,000 contributes £7,500. The second may deserve substantial attention, provided the stock funding and operating demands work. Chasing the highest percentage alone can overlook the product paying most of the bills.

Returns need care. The refund reduces revenue; return shipping, damaged stock and handling may create further costs. If the refund has already reduced sales, charging the full refund again as an expense double-counts the loss. If a returned item can be resold, its stock treatment should reflect that too.

Use this analysis to decide what to reorder, reprice, improve or stop promoting. Finding a weak product is useful when it changes the next purchase order.

Is marketing producing enough profit to justify the spend?

Your marketing reports and accounts should be reviewed together. The agency can explain campaign performance and positioning. The financial review should establish what the resulting sales leave and how much cash the business can commit to acquiring more customers.

My target for a scalable own-brand model is paid advertising around 10–20% of net revenue. That is £5–£10 of advertising for every £50 of revenue excluding VAT. Keep agency, creative, influencer and other marketing costs visible alongside it so you can see the full cost of the strategy.

In our example, paid advertising is 18% of revenue, within that target. Including agency and creative costs, the reported marketing cost is 21%. Both figures are useful, and they answer different questions. Being within the advertising target does not explain away the limited growth in contribution.

That blended advertising percentage is also different from customer acquisition cost. If repeat customers produce a growing share of sales, the blended figure can improve even while each new customer becomes more expensive to win.

Track first-order contribution, the cost of acquiring a new customer and repeat purchases by customer group over time. Where initial orders lose money, show when later purchases actually recover that cost. Future customer value is more convincing once customers have made the purchases.

The accounts will not tell a specialist how to improve an advert. They should give the founder and specialist a clear spending limit, a view of the financial results and the right questions to investigate.

Is stock supporting sales or absorbing the cash?

Stock is one of the most important reasons ecommerce accounts need more than a profit and loss report. You can make a good profit on the units sold while committing much more money to the units still sitting in a warehouse.

The balance sheet should show dependable stock quantities and costs across your own premises, Amazon, the 3PL and goods in transit where owned. Distinguish deposits and future commitments from stock already owned. Reconcile important balances rather than relying indefinitely on an old estimate.

Product costs should include the relevant landed costs, such as freight and duty, excluding recoverable VAT. Compare the cost of stock sold with the revenue it generated. A £60,000 shipment does not automatically become a £60,000 expense in the month it is paid for if much of it remains unsold.

Then add the operational questions. How many weeks of stock do you have by key product? What is the reorder point once production and delivery times are considered? Which lines are ageing, and are they still likely to sell at the expected price?

A range carrying £24,000 of stock at cost and selling through £3,000 of cost each month has around eight months of cover at that rate. That may be sensible ahead of a seasonal peak, or far too much for a product losing demand. The accounts identify the commitment; the founder’s knowledge helps explain it.

An average across the whole business can conceal a bestselling product about to run out and a slow range with enough stock to furnish the office. Review the lines that materially affect cash and sales.

Why did the bank balance fall when we made a profit?

Your accountant should be able to explain this without treating it as an accounting mystery.

Return to the current month’s £25,000 operating profit. Suppose the business bought and paid for £60,000 of stock, while the cost of stock sold was £25,000. Inventory increased by £35,000. That extra stock used cash without reducing this month’s profit by the same amount.

Assume the business also paid £8,000 of Corporation Tax for an earlier period and £4,000 of lawful dividends. For this simplified example, all other working-capital movements, non-cash adjustments and financing movements net to zero.

Movement in cashAmount
Opening bank balance£50,000
Add operating profit£25,000
Deduct additional cash tied up in stock£35,000
Deduct Corporation Tax paid for an earlier period£8,000
Deduct dividends paid£4,000
Closing bank balance£28,000

The business made £25,000 of operating profit and used £22,000 of cash overall. The next question is whether the stock investment will earn the expected return quickly enough to fund what follows.

In a real review, the explanation should also cover marketplace receivables, supplier credit, VAT balances, loan movements, asset purchases and anything else material. Loan repayments and dividends use cash without being operating expenses. Depreciation reduces profit without being a cash payment in that month.

Once those movements are understood, the bank balance becomes something you can plan around. It stops being a monthly surprise.

What tax is building up and what can we afford next?

The pack should show estimated Corporation Tax, VAT and payroll liabilities, with the expected payment dates. Update the tax estimate as profit expectations change, allowing for the relevant tax adjustments and reliefs. Do not assume that a fixed percentage of accounting profit is always the final bill.

Corporation Tax is usually due nine months and one day after the accounting period ends, although companies within instalment-payment rules pay earlier; associated companies can affect the thresholds. The practical requirement is to know your business’s amount and timetable.

A month’s profit is not the same as cash available for dividends. Check distributable profits after tax as well as the cash needed to trade. Dividends are distributions to shareholders, rather than costs deducted in arriving at operating profit.

Cash needed for a future tax payment can sometimes support growth in the meantime. The review should show how it will be replenished by the deadline, with room for slower sales or a delayed shipment. Used deliberately, that can help fund the business; used without a forecast, it becomes an unpleasant surprise with a due date.

Pair the monthly accounts with a rolling 13-week cash forecast, roughly the next three months, and a monthly view of the coming year. Put purchase deposits, shipment balances, marketing, payroll and tax on their expected dates. Update the shorter forecast weekly when commitments are changing quickly.

Before approving the next £40,000 order or a larger advertising budget, you should be able to see the lowest forecast cash balance and what happens if sales fall short. That is a better basis for confidence than the amount currently sitting in the bank.

Keep the measures focused on decisions

You do not need to review fifty ratios every month. I would start with a small set that explains the business, adding detail where there is a specific question to answer.

MeasureWhat it should help you decide
Net revenue and order mixWhether growth comes from demand, prices, discounts or a change in what sells.
Gross margin on landed product costWhether sourcing and pricing leave enough to fund the rest of the operation.
Contribution by main product and channelWhere the next marketing and stock investment should go.
Paid advertising as a percentage of net revenue, plus total marketing costWhether acquisition remains affordable as spending increases.
Operating profit in pounds and as a percentageWhether growth is improving the return after the actual overheads.
Stock cover, ageing and purchase commitmentsWhat needs ordering, what needs selling and where cash is already committed.
Forecast low point in cash and tax due datesWhether the next commitments can be funded with sufficient headroom.

For an own-brand model, I would aim towards landed product costs of 20–30% of net revenue and operating profit of 20–30% before finance costs and Corporation Tax, alongside the 10–20% paid-advertising target. Include realistic staffing and founder remuneration costs when assessing the underlying return.

These are commercial targets to plan and challenge against, rather than industry averages or a guarantee that every product can support them. The important thing is to know what your model needs, what it currently delivers and why there is a gap.

Get the accounts soon enough to use them

Agree a monthly timetable. For many growing brands, I would aim for reviewed accounts within around 15–20 working days of month end. The bookkeeping, marketplace reconciliations and stock information need a process that makes it achievable.

Include the costs belonging to the month even where the invoice arrives later, and spread prepaid costs appropriately. Otherwise, an annual insurance payment or a late 3PL invoice can make one month look poor and another unusually profitable. Identify material estimates and clear them when the actual information arrives.

The monthly pack should distinguish the original budget from an updated forecast. If sales or margins are falling short, revise the outlook without rewriting the original target out of existence.

End the review with a few actions, an owner and a date. For our example, those might be investigating the increase in fulfilment costs, checking the contribution from the additional advertising and reviewing the next stock payment against forecast cash. At the following meeting, ask whether those actions improved the result.

You remain responsible for decisions about the product, customers and growth. Your accountant should make their financial consequences easier to understand and challenge assumptions where the numbers do not support the plan.

The accounts should help you run the next month

Growing an ecommerce brand involves committing money before you know exactly what will come back. Monthly management accounts give you a regular chance to compare the plan with reality and decide where the next pound should go.

You should leave the review knowing what made money, what used cash, which commitments are approaching and what needs changing. Sometimes the right answer is to push harder. Sometimes it is to fix a margin, sell existing stock or give a new channel more time to prove itself.

At COPA, we help ecommerce founders connect monthly reporting with stock, marketing, tax and cash decisions. The aim is to make the figures useful while you can still act on them. Speak to us about management accounts for your ecommerce business.
