How we serve Mount Gambier

  • Progress claims tracked

    When a job is billed in stages, each claim goes into your file as an invoice of its own, and payments are applied to it as they arrive, so you can see which stages are still unpaid.

  • Held-back amounts kept in view

    If a client holds back part of a payment until the job is finished, the unpaid part stays on the invoice in your file instead of slipping out of sight.

  • Materials and parts bills matched

    Bills from materials and parts suppliers are entered as they come in, and each payment from the bank is paired with the bill it pays off.

  • A quote before the work

    We look at how many jobs, bills and bank accounts pass through your file in a typical month, then give you a price before any work starts.

Services for Mount Gambier businesses

What Mount Gambier business owners ask us

We bill big jobs in stages. How do you record that?
Each progress claim is raised as a separate invoice in your Xero, MYOB or QuickBooks file. When the client pays, we apply the payment to that claim, and any amount still owed stays visible on the invoice until it comes in.
We run a repair workshop. What does a month of bookkeeping cover?
We reconcile your bank accounts to their statements, enter the bills for parts and materials, and match customer payments to the invoices they settle. By the end of the month the file shows what customers owe you and what you owe suppliers.
Does the chart count farm and forestry businesses?
Yes. Agriculture, Forestry and Fishing appears among the larger groups in the industry chart. Those businesses get the same monthly routine, with the bank reconciled to its statements and supplier bills tied to the payments made against them.
Our books slipped behind during a busy run of work. Where do you start?
With the oldest month that hasn't been reconciled. We bring the file forward from there until it's current, then keep it that way each month.
How is the price worked out?
From the number of bank accounts, the volume of jobs and bills, and how far behind the file is. We quote before work starts, so the cost is settled before anything is done.
