Bay 2How GTX fits together
Each sale carries through the rest of the shop
A sale at the counter becomes a job in the workshop, a draw on stock, an order to a supplier and an entry in the accounts. Follow it through below, or go straight to the full feature list.
01 / The front counter
Every sale starts with the right customer
Whether it’s a set of tyres over the counter, a workshop job or a trade customer on account, GTX builds the sale around the customer, the products and their payment terms. All of it carries through to the invoice.
- Quote to invoice
- Keep the parts, labour and customer details together as the order progresses.
- Cash or account
- Handle counter payments, deposits and account customers in the same workflow.
- Find past sales
- Bring up the original transaction when a customer comes back or needs a credit.
02 / The workshop
Once it’s booked, the job gets a bay and a time
The business planner shows enquiries, bookings, quotes and work orders in one view. Give the job a bay or resource and keep the vehicle’s history beside it, so the counter can see how the work is going.
- Book a bay or resource
- Put bookings into time slots for bays, equipment or other resources.
- See the vehicle’s history
- Check the vehicle’s previous work and keep notes with the next booking.
- Follow up later
- Keep track of customer follow-ups and configured declined-service reminders.
03 / The stock room
Check the stock before you promise the tyres
Search by product code, name or tyre size to see what’s on hand and what’s already allocated, then add it to the order at that customer’s price. Purchasing, stocktakes and reporting all work from the same product file.
- Search and scan
- Search products and use barcodes to identify the right item.
- Price for the customer
- Work with customer discounts, markups, costs and configured promotions.
- Count and reorder
- Count, adjust and replenish stock using stocktakes and reorder levels.
04 / Suppliers
When stock runs short, order it from the job
Raise a purchase order from the work order that needs the part, then receive the goods and process the supplier invoice against it. With supported suppliers, electronic invoices save keying the details in again.
- Order from the job
- Create a supplier purchase order from the work order that needs it.
- Receive electronically
- Process invoices and credits through the supplier inbox with supported suppliers.
- Use the catalogue
- Enable Burson EzyParts or Repco Navigator Pro to bring catalogue results into GTX.
05 / The back office
The day’s sales are already in the accounts
Customer balances, supplier payments, the cashbook and the general ledger work from the same records as the counter. You can reconcile the bank, close the period and report on sales without entering anything twice.
- Customer and supplier accounts
- Work with customer statements, supplier balances and payment records.
- Reconcile the bank
- Compare bank activity with the cashbook and review unmatched transactions.
- Sales and financial reports
- Explore sales, purchase and financial reports, with settings saved for next time.
06 / The mobile app
Technicians update the job from the bay
The Marlin mobile app gives technicians their GTX planner tasks. From their phone they can update a job’s status, add notes and attachments, clock on and off, and run stocktakes.
- Job status updates
- Keep the front counter informed as planner tasks progress.
- Attachments and delivery
- Upload job attachments or record proof of delivery on the spot.
- Time and attendance
- Record time and attendance, with an optional connection to Marlin HR.
