Where should you invest in your business? Most small businesses get the best return by reinvesting profit in this order: a cash reserve first, then IT and cybersecurity, marketing that can be measured, keeping good staff, outsourcing non-core tasks, and equipment that raises output. Rank each option by expected return and payback period before spending.
Key Takeaways
- Survival is the first goal: US Bureau of Labor Statistics data show 77.9% of private-sector establishments opened in March 2024 were still operating a year later, and 51.4% of those opened in March 2020 survived five years.
- A cash reserve protects every other investment; the JPMorgan Chase Institute found the median small business held only 27 days of cash buffer.
- Large companies spent an average of 7.8% of revenue on marketing in 2026, according to Gartner’s CMO Spend Survey.
- IBM’s Cost of a Data Breach Report 2026 puts the global average cost of a breach at USD 4.99 million, which makes basic security one of the cheapest forms of insurance.
- Tax rules can lower the net cost of equipment: in 2026 US businesses can expense up to $2,560,000 under Section 179, and UK businesses can claim a £1 million Annual Investment Allowance.
Operating a business and a company relies on you to continually keep investing your profits into your business so that it will grow and succeed. This is especially important in the early stage of business development. Reinvesting at this stage can strengthen cash flow, sales and staff capacity, but only if the money goes to areas with a measurable return.
Spend time nurturing your business. It is one of the most important priorities. However, it can be difficult to know where to put your money and which aspect of your business you should develop first. The sections below cover the areas where small businesses most often reinvest – IT, marketing, people, outsourcing, cash reserves and equipment – with benchmark figures and a simple way to compare them.
IT department
Every day the world moves towards a more digital age where your business’ need for in-house technical specialists is essential. Having a well-developed and efficient IT support team is one of the best things your business can have.
Reliable IT support, whether it is an in-house specialist or a managed service provider, reduces the risk of downtime, data loss and security breaches. You do not want to be caught out by an IT failure and have to spend time looking for a solution when you could have one in-house.
Marketing
If you have been able to turn a reasonable profit early on in your business, then you have made a good step in the right direction. To increase your profits, you should really invest in marketing. It presents a really good way to improve your business’s success rate.
Marketing can get the name of your business out there and help improve your customer retention and exploration. Track the results of each marketing channel and move spending toward the audiences and channels that actually produce customers, rather than trying to appeal to everyone.
Your team
Keeping on top of recruitment and making sure that you can retain your competent team is essential to improving your business. You need to create a culture in your company that will attract hard workers and those who care about your business. One way to do this is to include lots of benefits for your employees. This can include discounts to local restaurants or health businesses as well as bonuses for continued service and good work.
Outsourcing
There are plenty of tasks in a business that people don’t want to do or that you aren’t as good as compared to other companies. You don’t need to be scared about outsourcing this work. This may be the most cost-effective method for dealing with these problems, especially in the early days.
There is no point spending lots of time on a task that you are not good at when someone more experienced can perform the same task in less time which will likely save you money. Invest some time and money in looking at people who can help you.
Investing in your business
It is natural to want to celebrate once the business starts making money. However, if you want to continue to make a profit then you need to invest in your business. Make sure that you spend time looking at where you can improve and see how your money can improve your productivity and profit.
How to Decide Where to Invest First
Every business investment competes for the same limited profit, so the practical question is which option returns the most for the least risk. A simple, repeatable method helps owners compare very different choices, such as a new laptop, an advertising campaign and a new hire.
- Protect cash first. Set aside a reserve before committing to long-term spending (see the cash reserve section below).
- List the options. Write down each possible investment with its full cost, including setup, training and ongoing fees.
- Estimate the return. Estimate the extra profit or cost saving each option should produce over 12 months.
- Calculate ROI. Return on investment (ROI) = (gain – cost) / cost x 100. A $2,000 tool that saves $3,000 of staff time in a year has an ROI of 50%.
- Check the payback period. Payback period = cost / monthly gain. The same tool pays for itself in 8 months ($2,000 / $250 per month).
- Start small and measure. Test with a limited budget, compare the result with the estimate, then scale what works.
For worked examples of the formula, see this guide to the return on investment calculator.
Build a Cash Reserve Before You Expand
A cash reserve is money kept aside to cover expenses when income drops or payments arrive late. The JPMorgan Chase Institute studied 597,000 small businesses using Chase Business Banking data from February to October 2015 and found that the median small business held just 27 cash buffer days, meaning it could cover about 27 days of normal outflows with no money coming in. Half of the businesses studied held less than a month of cash.
A thin buffer turns any slow month into a crisis and can force an owner to cancel investments halfway through. Building a reserve that covers at least a few months of operating costs before a major expansion gives other investments time to pay off. Separating operating money from the reserve also makes cash easier to track; this guide explains how to use a current account to manage cash flow.
Invest in IT and Cybersecurity
IT spending protects revenue as well as productivity. According to IBM’s Cost of a Data Breach Report 2026, produced with the Ponemon Institute, the global average cost of a data breach reached USD 4.99 million, a 12% increase on the previous year and a record high. IBM also reported a 56% increase in AI-driven attacks, led by deepfake impersonation and AI-enabled malware.
The US Cybersecurity and Infrastructure Security Agency (CISA) advises businesses to require multi-factor authentication (MFA) wherever possible, starting with email, file storage, remote access and administrator accounts. CISA ranks physical security keys as the strongest MFA option and text or email codes as the weakest. Low-cost priorities for a small business usually include MFA, automatic software updates, regular off-site backups and staff training on phishing.
Many small firms cannot justify a full-time IT employee, so a managed service provider is a common alternative. This comparison of in-house versus outsourced IT support sets out the trade-offs, and this list of risky cyber behaviors small businesses engage in shows where problems usually start.
How Much Should a Business Spend on Marketing?
Gartner’s 2026 CMO Spend Survey of 401 senior marketers in the US and Europe found that marketing budgets averaged 7.8% of company revenue in 2026, up from 7.7% in 2025. The respondents work at businesses with more than $1 billion in revenue, so the figure is a large-company benchmark rather than a rule for a small business. In Gartner’s 2025 survey, half of CMOs reported budgets of 6% or less.
For a small business, the more useful measure is cost per customer. Divide the spend on each channel by the number of customers it produced, compare that figure with the profit a typical customer brings in, and move money toward the channels where the gap is largest. This overview of the best types of marketing for a small business covers the main channels to test.
Invest in Keeping Your Team
Staff turnover is expensive. Gallup estimates that replacing an individual employee can cost one-half to two times that employee’s annual salary, and in Gallup’s research 52% of employees who left voluntarily said their manager or organization could have prevented their departure. Spending on training, fair pay reviews, clear career paths and better management often costs less than repeated recruitment.
Retention also affects customers, because experienced staff know the products, processes and regular clients. For teams that work partly or fully from home, these approaches to boosting employee retention in remote teams address the most common problems.
Equipment and Tax Allowances
Equipment and software that raise output or cut labor time are often the easiest investments to measure, and tax rules can reduce their net cost. The figures below are official limits; owners should confirm eligibility with an accountant, as the rules have exclusions.
- United States: According to IRS Revenue Procedure 2025-32, for tax years beginning in 2026 a business can elect to expense up to $2,560,000 of qualifying Section 179 property. The limit is reduced dollar for dollar once the cost of qualifying property placed in service in the year exceeds $4,090,000, and the Section 179 cost of a sport utility vehicle is capped at $32,000.
- United Kingdom: According to GOV.UK, the Annual Investment Allowance lets a business deduct the full value of most plant and machinery, up to £1 million, from profits before tax. Business cars do not qualify and are claimed through writing down allowances instead.
Business Investment Options Compared
| Investment area | Main benefit | How to measure it | Typical payback |
|---|---|---|---|
| Cash reserve | Survives slow months and late payments | Cash buffer days | Not a return; it is protection |
| IT and cybersecurity | Less downtime, lower breach risk | Downtime hours, incidents avoided | Hard to measure until something goes wrong |
| Marketing | New and repeat customers | Cost per customer, revenue per channel | Shorter for paid ads, longer for SEO and content |
| Team and training | Lower turnover, better service | Staff turnover rate, productivity | Medium to long term |
| Outsourcing | Access to skills without a full-time hire | Cost compared with in-house, time saved | Often immediate |
| Equipment and software | Higher output, lower labor time | Units per hour, hours saved | Cost divided by monthly saving |
Common Mistakes When Reinvesting Profits
- Spending the reserve. Investing every dollar of profit leaves no buffer for a bad month.
- Not measuring results. Without a before-and-after figure, there is no way to know whether an investment worked.
- Chasing large-company benchmarks. Figures such as Gartner’s 7.8% marketing budget come from firms with more than $1 billion in revenue.
- Ignoring the full cost. Software subscriptions, training time and maintenance can add substantially to the purchase price.
- Treating security as optional. IBM puts the global average cost of a single breach at USD 4.99 million.
Frequently Asked Questions
What is the best thing to invest in for a small business?
The best first investment for most small businesses is a cash reserve, because it keeps the business running while other investments pay off. After that, the best choice is the option with the highest measurable return and the shortest payback period, which is often basic IT security, a proven marketing channel or keeping skilled staff.
What percentage of profit should be reinvested in a business?
There is no official percentage for reinvesting profit; it depends on growth plans, debt and how much cash the owner needs to take out. A practical approach is to fund the cash reserve first, then invest in the options with the best return on investment and review the results every quarter.
How much should a small business spend on marketing?
Gartner’s 2026 CMO Spend Survey found an average marketing budget of 7.8% of revenue, but that figure comes from companies with more than $1 billion in revenue. Small businesses usually do better by setting a test budget, measuring cost per customer for each channel and scaling the channels that pay back.
How do you calculate the return on a business investment?
Return on investment is calculated as (gain – cost) / cost x 100. For example, spending $2,000 on software that saves $3,000 a year gives an ROI of 50%. The payback period, cost divided by monthly gain, shows how quickly the money comes back.
Is it better to outsource or hire in-house?
Outsourcing usually suits specialist or occasional tasks, such as IT support, bookkeeping or design, because the business pays only for the work it needs. Hiring in-house makes more sense for core, daily work where knowledge of the business matters. Comparing the full yearly cost of each option is the clearest test.
