How it works
One gig, start to finish: Smith wedding, 12 October 2026, Rosebank Estate.
Dave runs The Lowline, a five-piece wedding band, as a sole trader. He books the Smith wedding for $3,000. He plays himself and pays four other players $400 each. Every figure on this page comes from the same calculation the product runs.
1. Set your act up once
Dave enters his trading name, his ABN, whether he is registered for GST, and the state he works from. The state sets his local dates and paperwork; the super deadline itself counts business days nationally, the same for every payer.
He picks what he does: runs a band, runs an agency, or books performers for a venue. That changes the guidance he sees. It never changes the calculation.
2. Send one link, and the band fills itself in
Dave names the act and adds the one member he actually deals with. That is all he types. The act gets a single link, and he sends it however he already talks to them: the group chat, a text, an email. Each player opens the same address, adds themselves, and enters their own legal name, how they invoice, their ABN, whether they are registered for GST, their date of birth, their super fund USI and member number, and the account their fee goes to.
Dave never types a bandmate's bank details, and he does not need their contact details to start. The link is not spent by the first person to use it, nothing anyone enters can overwrite somebody else's answers, and the roster ticks over as each person finishes so Dave can see who is still outstanding.
Players never make an account and never download anything. The questions follow the answers: when Priya says she invoices through a company, the super questions drop away, because a payment to a company is not a payment to a person and her company handles its own. The page confirms that when she is done.
3. Create the gig and see the money before you commit
Dave adds the client, the fee, the date and the venue, and answers one question: who pays whom. Then he either offers the gig to the act, and the band confirms itself and splits the fee between whoever can make it, or he books the players himself and sets each fee. Either way the panel on the right fills in as he goes. Two of the four attract super and two do not, and the reason sits beside each figure.
| Player | Fee | Super | Why |
|---|---|---|---|
| Sarahbass | $440.00 | $48.00 | 12% of $400.00 ex GST |
| Marcusdrums | $357.14 | $42.86 | 12% of $357.14 ex GST |
| Priyakeys | $400.00 | . | Paid to a company, trust or incorporated association |
| Tomsax | $400.00 | . | Under 18 and 30 hours a week or less |
Marcus agreed his $400 includes super, so he receives $357.14 and $42.86 goes to his fund. Everyone else agreed super on top.

4. Invoices in both directions
Sidefill produces the tax invoice to the Smith family and a separate invoice from each player to Dave. Where the player is registered for GST, that invoice is a recipient created tax invoice with the wording the ATO requires, and the player's approval is the written agreement it needs.
Each player gets a message: “Dave has prepared your invoice for the Smith wedding, $440. Approve or request a change.” One tap. Approved invoices lock, and the super sits in a separate block on the document because it is not part of the invoice total.
5. Mark paid, and the clock starts
Dave pays the players from his own bank, then marks each fee paid. That date, not the gig date and not the day the client paid him, is what starts the super clock.

6. Send it, and keep the proof
Dave sends the super one of two ways: he downloads a clearing house file from Sidefill and gives it to the clearing house his bank or his accountant already uses, or he pays it himself and records the reference. Either way he tells Sidefill what he did, and the obligation moves from Due to Sent to Confirmed, and the evidence stays on the gig.
Sidefill never touches the money. It prepares the amounts and the files and records what happened, which is the part an accountant asks for.
