Introduction

Reading an article like this can provide valuable insight into how to improve your practice's profitability. However, as a clinician, first and foremost, there may well be a natural resistance to plough through all this detail. But there is a reward. Humint Online Software for Optometry can provide a single page with nine lines that you can use to manage your business's financial well-being. This article does not suggest that you become the accountant/bookkeeper for your practice, but as the decision-maker, you need to understand the importance of what is covered here. With Humint you can take control with a report you can assess in seconds. Converting turnover to a maximum net profit does not happen automatically; it requires control and up-to-date information. 

The right information

  Having the right information available at the right time, in a format you, the optometrist, can comfortably relate to, is the key to taking charge of your business's financial management. Not having your finger on the pulse of the practice can result in potentially disastrous financial losses, as will be shown below. Humint, because it has an integrated accounting package, can generate concise reports, providing the right information at the right time, but in a format you can relate to. This will empower you to grow your practice into a high-performance business.

The income statement as a management tool

This is what it can do for you:

  1. The turnover forecast provides a target to aim for   
  2.   It measures performance - Net profit
  3.   It provides an early warning system when things go wrong

Management accounts should be available for scrutiny by the 10th of the new month. The strength of the income statement as a management tool lies in the comparison it allows one to make against the forecast. This is a true measure of the practice’s financial performance. The variance column on the income statement immediately shows which line items require attention. The astute manager will use this information to fix these problems before they become disastrous.

The Mini Income Statement – the nine-line page that allows you to control and only takes seconds to read. This is an example:

  1. Turnover (Budget)
  2. Cost of sales (35%)
  3. Gross Profit % (65%)
  4. Expenses:
  5. Salaries (22%)
  6. Rent (15%)
  7. Finance charges (depends on loans)
  8. Other expenses 10%
  9. Net Profit (18% )

The mini income statement summarises the whole income statement in nine-item lines. The benchmarks in brackets, as a percentage of turnover, are what your practice should achieve. Benchmarks will vary by location, but the goal should be to achieve a 20% net profit. The Mini Income Statement is a one-minute check on the practice's financial well-being.

Expenses shown as "other" in the mini income statement must be and can be 10 percent or less of turnover. If not, it will be reflected, for example, in an out-of-control telephone account. This can easily be tracked in the variance column, and further investigation will always reveal the cause.

The primary issue is the net profit. The owner should be very clear about what the year-to-date net profit should be. If the net profit does not meet expectations, the mini income statement will immediately indicate where to start looking for the problem.

Salaries and rent are the two largest expenses. The salaries item, as a percentage of turnover, reveals whether one is over- or understaffed. Experience and records should show what turnover is possible with a certain number of workers.

All of these percentages should be taken in the context of the turnover. A really bad month will throw everything out of kilter, but the reason will be low turnover, which messes up the percentages. Before a new staff appointment is made, it would be prudent to check on the salary percentage.

Although the rent is, by and large, beyond one’s control, it helps to keep it fresh in one’s mind. However, if it is getting out of control as a percentage of turnover, there is a case to be made with the landlord, backed up with good financial reports.

The interest and depreciation line in the mini income statement relates to repayable loans or an operating lease for, say, equipment. The repayments over time usually equal interest plus depreciation. Beware that this can be quite complex. When purchasing an item on a lease, it is important to always bear in mind the impact on the income statement. The mini income statement will immediately reflect this position.

Repayable loans and leases will vary significantly from one practice to the next, depending on the gearing. This will usually be a heavier burden on new practices. Benchmarks will vary in terms of salaries and rent for mall practices, value mart practices, and rural practices. Over time, the numbers become significant to each practice.

The stock-take

An accurate monthly stock-take is essential to verify the physical stockholding. The stock variance is the difference between the physical stock and the figure recorded in the accounting records. It is made up of items, such as shrinkage (theft), breakage, and promotions. This figure is a cost to the business and should be included in the cost of sales figure. This, in turn, allows one to present an accurate gross profit percentage – an essential management tool. It is essential to know the monthly stock-take variance. Should there be a shrinkage problem, it is best to know the extent of it every month, as opposed to receiving a big surprise at year-end. The conventional system was to conduct a stock-take only at year-end. This is seriously outdated and a bad business practice. Just imagine what can go wrong with the stock in twelve months.

Gross profit percentage (GP%)

Gross profit is the rand value of the difference between what you pay for goods and what you sell them for. The GP% represents gross profit as a percentage of turnover.

This percentage is key to managing the business. The easiest way to improve a business is to increase gross profit, but it is also the easiest way to mess it up if the gross profit percentage (GP%) is not proactively controlled. Post-mortems are useless.

Practice management software must allow for daily management of the GP%. It is surprising how often the GP% is misunderstood, yet it is so important.

The formula is as follows:

Gross profit (mark-up) ÷ the selling price × 100 = GP%

or

Cost price ÷ selling price × 100 = cost of sales percentage 

The sum of the two will always equal 100. For example, if the GP% is 65 percent, the cost of sales percentage is 35 percent. Note that the GP% can only be influenced by factors that affect the cost of goods or the price at which they are sold. For example, rent or telephone has no impact on the GP%.

The GP% is a great management tool. In the Cape Winelands, one often sees roses planted among the grape vines. This is because the roses provide early warning signals of diseases that can affect the vines. The GP% can do the same for a business. It can warn the owner that any of the factors mentioned above are hurting net profit.

Knowing the industry benchmark for GP% can be an effective way of measuring business performance. Optometrists should achieve a GP% of 65 percent. High-performance practices can post a GP% as high as 70 percent. Once a GP% lags below the benchmark, it is essential that you immediately establish the cause and manage it every week.

Avoid poor buying

Three things can drive down the price of frames. The size of the order, terms of payment, and out-of-date styles. Outdated styles are often discounted but are best left alone. However, every effort must be made to capitalise on volume and cash buying. Impulsive buying without a clear strategy is the biggest threat to the GP%. Discounts will be forfeited by placing small orders from just about every sales representative who knocks on the door.

Work out the average invoice per patient

This number is derived by dividing the monthly turnover by the number of transactions done over the same period. This is not the average cost of a pair of spectacles – this includes all transactions, big and small. Over time, it becomes a very useful indicator of how well the team is selling. For instance, the number may run at R1 000 for a practice. Should it drop suddenly, it is vital for the owner to know this and to find out why it has dropped. It may well be that a new dispenser is not selling many frames with new prescriptions. The average turnover per patient can also serve as an incentive for all sellers in the practice. Raising it by a mere R100 can bring about surprising results to the bottom line.

Manage the remakes

Based on the writer’s experience over many years, remakes are acceptable at 2% of turnover in a practice with a cutting and fitting workshop. However, it remains one of the areas within the business that needs careful monitoring. Once again, there is very little to gain from a retrospective discussion of the remake figures. A report should be available to the owner every week. A remake report should be detailed enough to be traced back to the source.

TABLE

No-shows

Patients who do not show up for their appointments must be seen as a loss to the practice. You have a choice: Ignore it and lose them, or put management systems in place to get them back. Two no-shows per day can add up to a considerable amount over 12 months. By converting this potential loss into rands and showing it in monthly reports, you have a good incentive to turn the situation around. For example, one no-show per day (valued at, say, R3 000 in turnover each) over a 26-working-day month will amount to staggering annual losses.

R3 000 × 26 days = R78 000 × 12 months = R936 000 potential loss in turnover per annum. 

Disaster Report

The hypothetical scenario presented in the Disaster Report in Table 1 below tells a scary story. Practice A has a turnover of R200 000 per month and makes a healthy profit of R50 000 (25 percent) per month. Practice B, doing the same turnover, runs into trouble because most of the issues discussed go wrong, all at the same time. It makes a net profit of R21 400 (11 percent).

A swing of R28 600 for the month can mean that, if left unchecked, the practice is R343 200 worse off at year-end. While it is unlikely that all of these things will go wrong every month, all at the same time, it can certainly happen some of the time. This makes a case for monthly controls through accurate, real-time information.

It is much easier to detect and eradicate problems if the system is geared to address them on a monthly and even weekly basis. Doing an annual audit report after the horse has bolted does not serve many purposes.

TABLE

The above scenario shows that instead of posting a net profit of R600 000, profits were eroded to a mere R256 800 per annum.

Conclusion

Converting turnover to a maximum net profit requires control and up-to-date information. Two things are essential: A bookkeeper who can set up the right chart of accounts and a software package that can provide the correct information with ease and simplicity. This is what Humint Online Software for Optometry can do for you. It is an online software package with all the bells and whistles. It surpasses anything available to optometrists in South Africa to date. Having the right information, at the right time, in a format you can relate to, is the key to a high-performance practice.
