The largest agribusiness in the cattle feeding sector in the Pacific Northwest needed monthly invoicing that no standard ERP could produce: hundreds of customers, each billed on a calculation that changed with interest rates, geography, and live cattle counts. We implemented NetSuite and built a custom interest generation module to do it automatically. The work took four and a half months and saves their team weeks of effort.
The business
This is a technology-enabled agribusiness operating across several lines at once: custom cattle feeding, natural beef production, agricultural commodity transport, and the leasing of large numbers of cattle. Each of those has its own operational rhythm, its own cost structure, and its own accounting treatment — and they all have to reconcile into one set of books.
The leasing side is where it gets genuinely difficult. Leasing cattle at scale is a financing product wearing agricultural clothing. It accrues interest, it varies by location, and the underlying asset is livestock whose count changes continuously.
The situation
Customers are billed monthly, but the amount owed is not a fixed price on a price list — it is a calculation driven by several moving inputs at once: prevailing interest rates, the geographic location involved, and dynamic operational data including current cattle counts.
Producing those invoices meant working through the calculation by hand for each customer, every month, in spreadsheets. That is slow, it does not scale with the customer base, and — for a business with financing exposure — it is difficult to audit. When a number is produced by a person following a process they hold in their head, reconstructing how it was reached six months later is its own project.
Underneath that sat a structural problem. The business was growing into a multi-entity shape their existing setup could not hold.
What we built
A custom interest generation module
The centerpiece of the engagement. We built a module inside NetSuite that calculates monthly invoices for hundreds of customers from multiple variable inputs — current interest rates, geographic location, and dynamic operational data such as cattle counts — and generates the invoices automatically.
The hard part was never the arithmetic. It was encoding rules that had lived in a person’s judgment into logic that produces the same answer every time, and doing it inside the ERP rather than beside it, so every rate and input used in a calculation stays traceable.
Bulk invoicing and statement automation
Around the calculation engine, we automated the billing cycle itself — bulk invoice generation and customer statements, replacing a recurring manual process that consumed staff time every month and could not be caught up on once it fell behind.
Full NetSuite implementation
Complete ERP configuration, data migration, and security setup — plus the subsidiary structure the business needed to keep growing. Entity structure is the piece that is easy to defer and expensive to retrofit: it touches the chart of accounts, intercompany activity, and consolidated reporting, and every transaction posted before it is set up correctly may need revisiting later.
The outcome
- Weeks of staff time saved. Invoice generation that previously required manual calculation now runs automatically.
- Billing accuracy improved through standardized calculations and validation rules embedded directly in the ERP rather than applied by hand.
- Consistency across every customer. The same rules produce the same result, whoever runs the cycle.
- Auditability. All calculations, rates, and inputs are traceable within NetSuite, supporting stronger internal controls and reporting.
- Room to grow. The subsidiary structure means expansion no longer requires an ERP project to accommodate it.
Total engagement: four and a half months.
Why this one was hard
Interest-based billing driven by live operational data is not a standard NetSuite motion, and there is no module to switch on for it. Getting it right meant understanding the financing arrangement as a business before deciding how it should behave as a record — then building it so the accounting it produces holds up under audit and consolidation.
It also had to be built responsibly. Customization that fights the platform becomes a liability at the next upgrade. This module extends native NetSuite functionality rather than working around it, which is why it is still maintainable.
That is the kind of problem we look for. If your business has a process your ERP cannot currently describe, that is usually the constraint holding back everything downstream of it.
