Start with carrier documentation. Every load requires a rate confirmation showing what you agreed to pay the carrier. Keep carrier invoices, proof of insurance certificates, and W-9 forms. You need the W-9s when filing 1099s at year end for any carrier you paid $600 or more. Missing a 1099 triggers IRS penalties.

Load documentation includes bills of lading and proof of delivery for every shipment. These aren’t just operational records. They’re your proof that the service was performed if a shipper disputes an invoice or a carrier claims non-payment. Keep these accessible because claims can surface months after a load delivers.

Customer records need the same attention. Rate agreements, contracts, and every invoice you issue to shippers. Your accounts receivable aging report shows who owes you money and how long it’s been outstanding. In freight brokerage, the gap between paying carriers and collecting from shippers creates serious cash flow pressure. You need to see that aging report weekly or you’ll run into trouble.

Accounts payable tracking matters equally. Carriers expect quick payment, often within 15 to 30 days. Late payments damage relationships and make it harder to cover loads. Track what you owe, when it’s due, and what you’ve already paid. Reconcile carrier statements against your records monthly.

Profit by load is the number that determines whether your brokerage survives. The margin between what shippers pay you and what you pay carriers is your gross profit. Track this per load, per customer, and per lane. You need to know which customers and which lanes actually make money. Some brokers stay busy moving freight at a loss because they never track margins at the load level.

Keep regulatory documentation organized and accessible. Your broker authority, surety bond records (BMC-84 or BMC-85), and proof of process agent filing need to be available if the FMCSA audits you. Bond renewals and changes need documentation too. A lapse in your bond can suspend your authority.

Bank statements and reconciliations tie everything together. Every deposit should match customer payments. Every outgoing payment should match carrier invoices. If you’re using factoring to improve cash flow, those transactions need separate tracking since factoring fees eat into your margins.

The FMCSA mandates keeping broker records for three years minimum. For tax purposes, keep everything at least seven years. Digital storage works fine as long as records are organized and searchable.

Most freight brokers who fail aren’t losing loads. They’re losing track of money. Working with a Detroit area bookkeeping service helps transportation and logistics businesses set up systems that track all of this without drowning in paperwork. The records you maintain determine whether you can see problems coming or only discover them when cash runs out.
