The short version
- You don’t need to tidy anything before you start. Sorting first is the main reason people delay another six months.
- Week one is assessment, not judgement. We’re establishing what exists, not marking it.
- Most of a damaged record can be rebuilt from bank and card feeds. Missing receipts limit GST credits, not the reconstruction itself.
- Coming forward before the ATO contacts you materially changes the penalty position.
- A catch-up is quoted separately from ongoing work, and it can be staged if paying for it all at once isn’t realistic.
There’s a particular moment that happens before anyone calls a bookkeeper, and it usually happens at night. You’ve decided you’re going to sort it out. And then, almost immediately, you start thinking about what sorting it out will involve: someone else opening the bank feed, seeing the eleven months you didn’t reconcile, the shoebox, the invoices you meant to chase. Somewhere in there the decision quietly gets postponed again.
So this isn’t an article about what bookkeeping is. You already know. This is an article about the thirty days after you pick up the phone: what we ask you for, what we typically find when we open the file, how long it takes, what it costs, and what happens if what we find is worse than you thought.
What we ask you for before we start
Less than you’d expect, and none of it needs to be organised. The list is short on purpose, because a long list is what stops people.
- Bank and credit card access. Read-only feed access into your accounting software is ideal. If that’s not set up, statements as PDFs for the period we’re covering will do.
- Your accounting software login, if you have one. If you’ve never used any, that’s genuinely fine. It’s more common than you’d think, and setting it up properly from scratch is often faster than fixing a file someone has half-configured.
- Your last lodged Business Activity Statement, or the honest answer that you don’t know when the last one was. Both are workable starting points.
- Payroll records, if you have employees: employment agreements, pay rates, and whatever Single Touch Payroll reporting has been happening.
- Loan, lease and asset documents for anything the business is paying off, because these are the items most often miscoded and the hardest to reconstruct later.
- Your Australian Business Number and GST registration details, which we can confirm ourselves if you’re not sure.
If you haven’t got something on that list, say so and we work around it. Bank feeds cover a surprising amount of ground on their own, and the gap between “I don’t have that” and “that can’t be done” is much wider than most people assume. The only genuinely awkward one is bank access, because without it we’re reconstructing from the outside.
Please don’t. Every hour you spend pre-sorting receipts is an hour spent guessing at a system we haven’t designed yet, and it’s usually work we redo. Hand it over as it is. The mess is information. It tells us where things went wrong.
Week one: what we actually find
Week one is assessment. We’re not fixing anything yet; we’re establishing what’s actually there, which is the only way to quote the rest of the work honestly.
Books arrive in a fairly predictable range of conditions. At the manageable end, someone has been using Xero properly, has fallen two or three quarters behind, and the bank feed is intact. The transactions are all sitting there, unreconciled, waiting. That’s a straightforward catch-up.
In the middle, and this is where most first-time clients sit, there’s software that was set up once and then drifted. A chart of accounts that doesn’t match how the business actually operates. Personal and business spending running through the same account. Transactions coded to a suspense account by whoever set it up, and never revisited. GST applied inconsistently, so some quarters look plausible and others clearly aren’t.
At the difficult end, there’s no software at all, or there’s software nobody has opened in two years, and the entire record is bank statements plus memory. This still gets fixed. It just takes longer, and the substantiation conversation becomes more important.
An allied health clinic, seven months behind. Xero was set up properly and the bank feed was complete, so roughly 600 transactions were sitting unreconciled but intact. Two activity statements were unlodged. The only real problem was that private health rebates and patient gap payments had been landing in the same account and coded as one revenue line, so the practice had no idea which service types were actually profitable.
A sole trader builder, fourteen months behind. One bank account for the business and the household, which is the single most common thing we see. About $40,000 of transactions had been dropped into a suspense account by whoever set the file up, and never revisited. GST had been claimed in full on a ute that was partly private use, which needed apportioning and correcting rather than simply re-coding.
A café, two and a half years behind. No accounting software at all. The record was bank statements, a carrier bag of dockets, and the owner’s memory. Daily takings had never been reconciled against the merchant facility, so card settlements and cash sales had to be rebuilt from two directions and matched. This one took the longest, and it still got done.
Weeks two and three: rebuilding the record
This is the reconstruction. Most of it is less mysterious than it sounds: bank and card feeds establish that money moved, when, how much, and to whom. From there we work out what each transaction actually was and code it correctly.
What survives without receipts is more than people expect. A bank line showing a payment to a supplier you use every month, for an amount consistent with what you always pay them, sitting alongside twenty similar payments, is reasonable evidence of a business expense. What that bank line can’t do is prove how much GST was in it.
That distinction is the practical heart of the receipts question. To claim a GST credit on a purchase over $82.50 including GST, you need to hold a valid tax invoice. Under $82.50, a receipt, a cash register docket or an invoice will do, and if you have none of those, a contemporaneous record showing the supplier’s name and ABN, the date, a description and the amount paid is acceptable. Above $82.50 with nothing at all, the safe treatment is to claim no GST credit rather than claim one you can’t support.
Two things worth knowing while we’re in this part of the process. Suppliers have 28 days to give you a tax invoice when you ask for one, so a week or two of chasing during a catch-up often recovers credits you’d otherwise write off. And there’s a four-year limit on claiming GST credits, which means very old periods can reach a point where the credits are simply gone, even though the expense was real.
Substantiation and record-keeping requirements described here reflect current Australian Taxation Office guidance: business records must generally be kept for five years, a tax invoice is required to claim GST credits on purchases over $82.50 including GST, and GST credits are subject to a four-year claim limit. Figures and thresholds current as at August 2026.
Week four: the first accurate picture
By week four there’s a reconciled set of numbers, and this is usually the part that surprises people, not because the numbers are bad, but because they’re different from the version that was in their head.
The pattern is consistent enough to describe. Revenue is often close to what the owner guessed. Costs are almost never. Subscriptions nobody cancelled, a merchant facility charging on a rate that was renegotiated verbally but never actually changed, one service line that’s been quietly priced below cost for a year, and accounts receivable with genuinely old debt in it that the owner had stopped thinking of as collectable.
If that gap between the reported profit and the bank balance is the thing bothering you most, it has its own article: profitable on paper, nothing in the bank.
A small agency came to us about nine months behind. The first clean quarter turned up $9,400 a year in software subscriptions still being charged: three tools that duplicated each other, and one platform that had been cancelled by email but never actually stopped billing.
The more expensive discovery was quieter. Their largest retainer client hadn’t been repriced in four years, while the scope had grown twice. Once the time against that account was costed properly, the work was being delivered at a slight loss. Nobody had done anything careless. It was simply invisible until the numbers were accurate enough to show it.
Where an unpaid superannuation liability shows up, that’s the one we deal with immediately rather than at the end, because super has its own timing rules and its own consequences and those don’t wait for the rest of the catch-up.
What it actually costs and how long it really takes
A catch-up is scoped and quoted on its own, separately from ongoing support, so that your regular monthly work starts from a clean slate rather than dragging historical problems through it.
What moves the number, in roughly the order it matters:
- How many months are outstanding. The single biggest driver, and it isn’t quite linear. Older periods are slower per month because substantiation is harder.
- How many accounts, cards and payment platforms are involved. Four accounts and two card facilities is materially more work than one of each.
- Monthly transaction volume. A consultancy issuing twelve invoices a month and a café running hundreds of daily card transactions are different jobs at the same number of months behind.
- Whether payroll is in scope. Payroll catch-ups carry superannuation and Single Touch Payroll obligations that have to be corrected in the right order.
- Whether previous Business Activity Statements were lodged, and whether what was lodged was right. Unlodged is often simpler than lodged incorrectly, because incorrect lodgements have to be revised.
- The state of the software file. A clean file two years behind can be quicker than a badly configured file six months behind.
How long it takes is easier to be straight about than what it costs, because the timeline depends mostly on volume rather than on your particular circumstances.
- One or two quarters behind. Usually two to three weeks from getting access to being current and lodged.
- About a year behind. Typically four to six weeks, with most of the variation coming from how much chasing of tax invoices is worth doing.
- Two years or more. Usually two to three months, and often staged, so that the current period is compliant early while older periods are worked through in agreed blocks.
Payroll in scope tends to add time rather than change the shape of it, because superannuation and Single Touch Payroll corrections have to be made in a particular order.
What we can commit to without seeing your file is the sequence: we quote after week one’s assessment, not before it, and the quote is a fixed scope rather than an open hourly meter. If you’d rather see how ongoing support is structured first, that’s on our pricing page, and the detail of what a catch-up covers is on our catch-ups and clean-ups page.
Will I get in trouble for how far behind I am?
This is the question people most want answered and least want to ask, so here it is directly.
Your bookkeeper is not going to report you. A registered BAS agent’s role is to get your lodgements accurate and current. What we will do is tell you exactly what we’ve found, including anything you won’t enjoy hearing, and set out the options.
On the ATO’s side, the position is more forgiving than the anxiety suggests, but it is time-sensitive. Two mechanisms matter:
Failure to lodge penalties accrue per outstanding document. For a small entity, the penalty is one penalty unit for each 28-day period, or part of one, that a document is overdue, capped at five periods. The penalty unit is $364 for lateness from 1 July 2026, which puts the maximum at $1,820 per document. The word doing the damage there is “per document”: eight outstanding activity statements are eight separate penalties, not one. This is the main reason it’s worth stopping the bleeding before working backwards.
Voluntary disclosure is where coming forward changes the outcome. If you tell the ATO about a shortfall before they notify you that they’re going to examine your affairs, the base shortfall penalty is reduced by 80%, and if the shortfall is under $1,000 it’s reduced to nil. Once the ATO has contacted you, the same disclosure is worth substantially less. Practically, that means the gap between “we found it and disclosed it” and “they found it” is the difference between a manageable number and an unpleasant one.
Penalties can also be remitted on the basis of your circumstances and compliance history, which is a separate request and a separate conversation. It exists, it’s used, and it’s worth asking about.
If unlodged activity statements are the specific thing keeping you up, we’ve written that part out in full detail separately: what actually happens when you haven’t lodged BAS in months.
Penalty figures reflect the Commonwealth penalty unit of $364 applying to conduct from 1 July 2026, and the ATO’s published voluntary disclosure reductions. Penalty units are indexed periodically. Current as at August 2026. We’ll confirm the position that applies to your specific periods before anything is lodged.
The part people are most embarrassed about
Nobody who calls us is the worst we’ve seen. That sentence gets used a lot as reassurance, and it’s usually asserted rather than demonstrated, so here’s the demonstration.
Three years of unlodged activity statements. No accounting software. The records arrived in supermarket bags and two shoeboxes, and a portion of the invoicing had only ever existed on a laptop that had since died. Business and personal spending ran through the same debit card for the whole period. There was unpaid superannuation for two casual staff, which is the part that genuinely mattered and the part the owner hadn’t realised was a separate problem with its own rules.
It took a little over two months, staged so the current year was compliant first. The super was dealt with immediately rather than last. The outcome was a payment arrangement and a voluntary disclosure, not a catastrophe, and the owner’s business, throughout all of this, was doing well. That was rather the point. They had been too busy earning to file.
The thing we’d actually want you to know is that the state of your books has almost no correlation with how well your business is doing, or how capable you are. The people furthest behind are usually the ones whose businesses grew faster than their admin systems, which is to say, the ones who were busy working. Falling behind on reconciliation is a bandwidth problem, not a character problem.
What changes afterwards
Once the catch-up lands, the work becomes rhythm rather than rescue. Transactions are reconciled on a regular cycle instead of in a panic. Activity statements are prepared from numbers that are already right, which is a very different activity from assembling them from scratch each quarter.
Because we lodge as a registered agent, eligible quarterly activity statements also fall under the BAS agent lodgement program, which carries later concessional due dates for most quarters: a few extra weeks of breathing room that self-lodgers don’t get.
The part clients mention most, though, isn’t the compliance. It’s that they stop carrying it. The end of the quarter stops being a thing they dread, and they stop having a running background estimate in their head of how bad it’s got.
The Lady Abacus takeaway
The longer this gets left, the more the problem changes character. A catch-up postponed for another year isn’t just a bigger version of the same job. It’s a job where more of the evidence has aged out, more failure to lodge penalties have accrued per document, and more GST credits have passed the four-year mark and become permanently unrecoverable. The bookkeeping cost of waiting is modest. The substantiation cost of waiting is the one that doesn’t come back.
Which is a fairly unromantic way of saying: the worst version of this is the version where nothing happens. Everything else is workable.
