Client highlight: VENETIAN PLASTER GALLERY MELBOURNE

If you’ve watched The Block, you might already be familiar with some of their work.

Having made a name for themselves for creating spaces with artistic finishes and feature walls, they’re meticulous at what they do.

They’re specialists in stucco application, Venetian plaster and microcement, from statement walls to floors and custom-built pieces.

“His knowledge, professionalism and attention to detail have been outstanding”

When you’re trusting someone with your business, you want to know they’re paying attention to the details, giving you honest advice and taking the time to make sure you understand what it means for you to.

This is exactly the standard we set when people choose to work with us.

Small business owners, this one's for you. From October 1st, you'll no longer be able to add a surcharge when customers pay by card.

The surcharge is going, but the fees your business pays aren't.

So, if you're a business that takes a lot of card payments, particularly Visa, Mastercard or American Express transactions, those fees could start eating into your profit if you've previously been relying on passing the cost on to customers.

First, check where you're currently adding card surcharges and make sure they're removed before October 1st. Think eftpos terminals, online payment settings, invoices, menus, signage and your website.

Then have a look at what you're actually paying to accept card payments, including your merchant fees and transaction costs.

Once you've got those numbers, you can work out how much it's going to cost your business each month, whether you can afford to absorb it, or if your prices need adjusting to cover the difference.

Contrary to popular belief, accountants do more than just tax returns....

Got a BAS due and you’re not quite sure what you’re looking at? Xero is six weeks behind? Thinking about an SMSF? Or there’s a decision coming up in the business and you want to understand the numbers before you make it?

We look after the tax and compliance side, keep the books current, help with SMSFs, and when there’s a bigger business decision on the table, we can help you work through that too. 👋🏼

ATO isn't auditing you at random. If you've found yourself on their radar, there's usually a reason for it.

They're usually looking for patterns of behaviour that attract attention over time.

Consistently lodging late. Leaving income off your return. Claiming deductions you can't support. Reporting business losses year after year. These are the kinds of things that start raising questions.

The best way to avoid unwanted attention is pretty simple. Keep good records. Lodge on time. Declare all of your income. And if you're ever unsure, ask before you lodge.
