PAYROLL : Error in 2025 Tax Tables
There is an error in existing tax tables that has been in place all year undetected. Throughout 2025 c9 overcharged tax by about $4 to $5 a week because of an incorrectly inputted tax bracket. Since it is nearly the end of the financial year we are going to leave this in place. All employee payments made using c9 payroll can expect a slightly higher tax return as a result.
2026 FY onwards we are migrating to a different methodology for handling tax tables. The ATO publish tax tables in form of excel spreadsheets for software developers. For years these have been baked into c9 but we never enabled them as a default tax computation methodology. The reason for this is that the way the excel files are designed and math in them; it is difficult to reason about the results and cross reference them with actual tax legislation and validate their accuracy. The thinking was that it was more likely that using this dataset will cause computation issues. Given the 2025 undetected error we are reconsidering this and decided to pivot to this data and perform some basic spot checking / automated testing from 2026 FY onwards; and trust/rely on ATO to publish error free formulas.

C9 Repository changes – Stihl Pricefiles
We are bringing Stihl into our price file repository. This forces a change in repo importing to allow for optional support of per dealer discount codes.
This change requires us to “fence” off our repository from older versions of c9. Older versions of c9 will not see any c9 repo changes. You must update c9 first in order to access future price file updates in the repo.
Other tweaks and fixes
Low Level / technical changes
Includes DB changes. You need to close and reopen c9
Important Change – messenger
This version of c9 enforces ‘restrict messenger’ mode so that messenger only runs on computers which are explicitly configured to run it
Some dealers might have c9 in permissive mode and will find messenger will not start at all. To fix on main computer goto setup -> main setup screen -> system and database tab. Make sure ‘allow’ option indicated below is selected, save then close and reopen c9
Basic fixes / tweaks
Complex tweaks / fixes
Small tweak to cope with using barcode scanners via remote c9 where barcode is configured to transmit STX.
In point of sale screen the barcode would misread as ’42’ instead of actual barcode. This version includes a temporary fix that makes such scanners work.
One subtle variation between remote and local STX programmed barcodes is remotely for now , barcode scanner will behave as though it wasn’t programmed. You’ll need to manually key in qty sold in point of sale for example.
ACMA (Australian Communications and Media Authority) are mandating stricter controls over Sender IDs on SMS to minimise fraud and scams.
A SMS message like this has the sender listed as BCMOTO
ACMA now require a much stricter process for getting their Sender ID into your SMS messages. If this process is not completed by July 1 your messages from July 1 will now look like this:
IF ACMA requirements are not done then the sender ID will no longer be transmitted , instead it will come from a 04 number controlled by us at C9 and the original Sender ID will not embed at the start of the message.
Make sure you are running latest version of c9 (v5.2.155).
Then Goto setup -> other settings and pick Magician/SMS/Email. Goto SMS tab. Note the From SMS you can see there already (e.g. BCMOTO). Click Request Change button
Retype the Sender ID you want. Ideally keep it the same as what is already there but make changes if you need. Review all details and make sure they are spot on.
Then click ‘send Request’ button
The above will send c9 the request. We will review and submit to ACMA. Once submitted to ACMA you will receive an email requesting approval for the Sender ID. Click on the link and follow instructions. You will need to create an account on ACMA website linked to supplied ABN. You may need to use a principal contact email linked to your ABN which may well be your accountant.
Once you are logged into ACMA you should be able to see a request for Sender ID sent from C9 Software and from there you can approve it.
Once approved by you ACMA will review and approve / reject request.
End to end the whole process can be expected to take a few days to a week. Make sure you get on this early, especially as we expect a rush to sort this out, Australia wide closer to July 1.
Over the weekend Nuvei suffered yet another issue with integrated terminals.
C9 now recommends against using Nuvei terminals in integrated mode. Our assessment of the solution is that it is not fit for purpose. There are two major concerns driving our assessment.
Broadly the terminals themselves seem pretty comparable to other industry products in terms of the general fit for purpose. Also their online payment gateway for websites also is operationally fine. The recommendation against using Nuvei in store in integrated mode is because the mechanisms which allow c9 (and other point of sale systems) to interconnect and drive the transaction are highly problematic.
1. Reliability : the system suffers outages and has suffered them for some time. Outages correlate strongly to times of high retail activity (e.g. Saturday mornings) and previously Nuvei disclosed to us past outages at least were caused by service load issues. That these problems continue to occur is a serious concern.
2. Accuracy : we have often encountered scenarios where the systems we connect to misreport the status of the transaction and show a different result in comparison to merchant portal. Several times we have queried Nuvei on this and we have not received any clarification. We suspect the system merely presents outcomes as known at time of txn and final transaction outcomes are not reconciled into or accessible to the systems they provide for interconnect.
To disable EFT integration globally.
Setup -> Main setup screen -> Payments. Identify the payment method(s) linked to eftpos. Click more button
Uncheck option, Integrate into PC-EFTPOS/Tyro. Click Close then OK on prior screen
DB / Messenger Changes – You need to log all terminals out with this upgrade
Sender ID registration changes to support July 1 ACMA requirements. Details of this are very important but will be covered in another separate post shortly.
Tweaks and fixes
Bugfix with recent changes to new/used unit flag setting on purchase unit.
In scenario where unit doesn’t exist against the customer and you add it for the first time, the purchase unit screen will scrub unit details at various points making it impossible to add a new unit for purchase in this screen. Floor stock purchases unaffected.
Underneath this is a subtle design issue which is now also fixed. Previously c9 may have flipped the new/used flag at random times during process of inputting a unit to purchase. This should no longer be happening either from now on.
Includes DB Changes. You need to log terminals out during upgrade
Features and high impact fixes
Other Bugs
Minor tweaks /tiny fixes
Low level changes
From June 2026, single touch data submission requires a new security step to authorise c9 to send this data.
Basic outline
Without the above STP submissions will fail.
