From Billing Blind Spots to $26K in Recovered ARR - Why I built TwineBiller
The Profile
Trent Yesberg
Founder, Twine Apps
Accounting Firm Owner & Practitioner – Regional Business Services, Townsville, QLD
Trent didn’t build TwineBiller as a theoretical solution. He built it because his own firm had a problem.
The Problem: A Time-Heavy Process That Quietly Cost the Firm Money
Like many modern firms, Trent’s practice resold wholesale software subscriptions to clients. On paper, it looked simple. In reality, it was messy.
Before TwineBiller:
A dreaded, day-long billing process
Reliance on memory and manual checks to catch errors
Frequent write-offs due to missed price rises or expired discounts
Every month, there was a problem.
Sometimes it was a missed price increase.
Sometimes a discount that ended (3 months ago).
Sometimes a client who hadn’t been billed for their software for 6 months.
Each individual amount felt small.
But small amounts compound.
“With our turnover it was easy to think it was only small dollars, but all those small amounts add up very quickly.”
Worse still, these weren’t pricing strategy decisions. They were accidental giveaways.
The Turning Point: Building TwineBiller
Trent scoped TwineBiller to help the billing picture become clear:
Fixed-fee clients were separated and clarified
Clients set up correctly from the outset and automated
Bring transparency by separating services from software
Have measurable revenue impact while delivering a wholesale benefit to our clients
The Results: Faster Process. More Revenue. Zero Client Disruption.
After TwineBiller:
Firm wide subscription billing now takes ~30 minutes
Full visibility over subscription costs, margins and pricing
Integrated into current processes and workflow
No client disruption — business as usual
And the most tangible outcome?
$26,000 in Additional Annual Recurring Revenue
Not from raising prices.
Not from selling more.
From billing correctly.
Revenue that was already earned, but not consistently captured.
The Bigger Insight
The real issue wasn’t effort.
It was visibility.
Modern firms run on dozens of subscription apps. When you resell those subscriptions to clients, you’re running a micro SaaS business inside your accounting firm.
Without a system designed specifically to manage subscription reselling:
Discounts expire unnoticed
Price rises aren’t applied
Clients go unbilled
Revenue erodes quietly
Trent didn’t build TwineBiller to “improve billing software.”
He built it to eliminate revenue erosion in firms like his.
The Before vs After Snapshot
Before
Monthly, day-long, manual subscription billing process
Billing blind spots
Reactive half-yearly reviews
Revenue leakage accepted as normal
Frequent small write-offs
After
$26K recovered ARR
Ongoing clarity and control
30-minute streamlined billing process
Full subscription visibility
Billing confidence restored
If you’re reselling subscriptions inside your firm, here’s the uncomfortable question:
How much revenue are you unintentionally gifting each year?
TwineBiller was built by a practitioner who got tired of guessing.
