Every company that struggles with complex invoicing eventually buys more software to fix it. A new ERP module, a billing add-on, a better spreadsheet. A year later they are still chasing the same line items. The reason is simple, and it is uncomfortable: the problem was never the software.
An ERP or accounting system assumes the invoice is clean by the time it arrives. In real operations, especially in freight, the invoice is the consequence of a chain of judgments: which carrier got a manual rate override, which customer has a special accessorial deal, which exception is fine and which one is a problem. Those rules live in the heads of the people who have done the job for years. The software never sees them.
That is why the numbers stay bad no matter how much you spend:
None of those are software bugs. They are operational decisions that never got captured.
Anyone can automate a clean, rules-based invoice. The money is in the exceptions: the tribal knowledge about who, when, and why. Most tools run away from that because it does not fit a tidy schema. It is the only part worth doing.
You fix complex billing by capturing the decisions, not by replacing the system that records them. Sit with the people who run it, write down the rules they carry in their heads, and turn those rules into agents that run on every load. Keep the agents inside the tools the team already uses, and keep a human on every consequential call. The invoice gets clean because the decisions upstream finally got encoded.
This is the whole idea behind Rigby. We do not sell you a new billing platform. We learn your rules, build agents that run them, and leave the money movement and the ledger exactly where they are. The carrier invoice audit and the AR inbox automation are not features, they are captured operations.
Treat complex invoicing as what it is, an operations problem, and the fix changes from "migrate to a new system" to "capture the rules you already run." That is a far smaller, far cheaper, far faster project, and it is the one that actually moves the number.
