Do you work with waste brokers or haulers?

Both — the pain is the same shape: thousands of vendor invoices, contract rates nobody re-checks, and pass-through charges that never get billed on. The buyer is usually a controller, CFO, or operating partner at a PE-backed platform.

We run two ERPs after an acquisition. Does that matter?

It affects the scope. We assess access, data definitions, and posting requirements for each ERP, then design routing and review steps for the systems that need to coexist.

How is this different from buying AP software?

Software ships generic rules and a new system to adopt. We encode your exceptions — hauler rate sheets, fuel surcharge tables, pass-through clauses — inside the flow your team already runs. You keep a review queue, not another login.

What does an engagement look like?

Two weeks inside your AP flow, fixed fee: we map the rules, quantify the leak in your own numbers, and hand you a ranked opportunity map. The audit fee credits toward the first build if you continue; the map is yours if you do not.

Is our data safe to share?

We work inside your environment and your vendor relationships, under your agreements. Engagements are anonymized in everything we publish — problem, buyer, and scale only, never names.

Waste & Environmental Services

AI for waste and environmental services companies.

Brokers and haulers manage thousands of vendor invoices a month. We help design rate checks, pass-through rules, and approval steps around the way your AP team works.

The pain map

Margins leak one invoice line at a time.

From operators running AP inside waste brokers and haulers — national footprints, thousands of vendors, tens of thousands of bills a month.

Hauler price creep
Rates drift up a few dollars a pull, hidden inside fuel surcharges and environmental fees. Haulers react to invoice totals, so micro-variances at line level stay invisible — until someone reads every line.
Pass-through charges you eat
Fuel surcharges, environmental fees, and customer-driven fees go largely unapplied — billed through to no one, absorbed by you. Operators describe eating nearly all of them; the leak runs to millions.
Bills with no PO behind them
Legacy sites and acquired routes send invoices with no purchase order at all. The first job is just classifying and routing them — before any matching can happen.
Two AP processes after every acquisition
Every roll-up inherits another ERP and another AP flow. The consolidation debate runs for quarters; the bills arrive daily and need routing now.
Payment files that fail
Payment runs fail two to four times a week, and the haulers feel it. The AP team spends Fridays apologizing instead of auditing.

Where AI pays

The workflows worth encoding first.

Potential workflows to assess against your data, contract terms, and review requirements. Scope and operating controls are agreed before the build.

Workflow

AP recovery audit

Compare hauler and supplier invoices with contract rates and surcharge terms, then route potential discrepancies for review before payment.

Capability

Invoice-to-PO matching

Read and classify bills, propose PO matches by service location, and route uncertain matches for review. Agree posting controls with your finance team.

Workflow

Pass-through charge capture

Check fuel and environmental surcharges against customer contract terms and flag eligible charges for the billing team to review.

Capability

Sales order processing

Read incoming orders, compare them with SKU and pricing data, and prepare an ERP entry with the review steps your team requires.
