How Dave the Drainlayer Got His Fridays Back
By Jotter Team
The old routine
Dave has been laying drains in the Waikato for 14 years. He runs a crew of four -- himself, two operators, and an apprentice. For most of those years, the invoicing process looked the same: finish jobs during the week, then sit down on Friday afternoon (or Saturday morning, when Friday got away from him) to type everything into Xero.
He would flip through a water-stained notebook, trying to read his own handwriting. How many metres of pipe on the Henderson job? Was that a 100mm or 150mm? Did he charge for the extra hour when they hit rock? The materials were the worst -- he would buy fittings from Mico during the week, throw the receipts in the glovebox, and then try to match them to jobs five days later.
"I reckon I was losing two to three hours every Friday just on invoicing," Dave says. "And I know I was missing stuff. You forget the small things -- an extra bag of metal, a second trip to a site. It all adds up."
What changed
Dave started using Jotter in April. The setup took him about five minutes -- he connected his Xero account, applied the Drainage industry pack (which gave him pre-built item tags for excavation types, pipe sizes, and ground conditions), and invited his crew.
The key change was not the app itself -- it was when the data got captured. Instead of writing things down and entering them later, his team tracks jobs as they work. Each morning, Dave creates the day's jobs in Jotter and assigns them. His crew starts timers when they arrive on site and adds materials as they use them.
A typical day now
6:30 AM -- Dave checks the day's schedule and creates two new jobs in Jotter. Picks customers from his Xero contacts, adds line items from his standard list: excavation, pipe supply, backfill, reinstatement.
7:00 AM -- His crew heads to separate sites. Each person starts their timer on their assigned line item.
12:00 PM -- Lunchtime. One of his operators adds "6m 100mm PVC pipe" and "2x 100mm bends" to the materials list for his job. Takes about 20 seconds.
3:30 PM -- First job is done. Dave reviews the line items, checks the tracked time looks right, and marks the job complete. The invoice appears in Xero before he leaves the site.
4:00 PM -- Second job wraps up. Same process. Two invoices in Xero, accurate to the minute and the fitting.
The results
"Friday afternoon is just... Friday afternoon now," Dave says. "The invoices are done by the time I finish the job. I do not sit at the kitchen table typing things into Xero anymore."
He estimates he is capturing an extra three to four hours per week that he used to forget to invoice. At his hourly rate, that is around $350 per week -- over $16,000 per year in revenue he was previously leaving on the table.
His accountant noticed the difference too. "She said the invoices are cleaner. Proper line items instead of 'drainage work -- various.' She does not have to call me to ask what things mean anymore."
What Dave would tell other tradies
"I was sceptical about another app. I tried one of the big ones a couple of years ago and my guys refused to use it -- too complicated. Jotter is different because it does not try to do everything. It tracks the job and sends the invoice. That is all I needed."
"Start with one job. Track it properly. See what the invoice looks like in Xero. You will be sold."
