Diesel TMS is proud to announce a tool on everyone’s wish list: Double-Entry Accounting + General Ledger + E-Payroll—FOR FREE. DEAGLE is the strong accounting backbone every transportation business needs—built-in to Diesel TMS.
For years, operations ran in the TMS while accounting lived elsewhere: spreadsheets, bank portals, separate bookkeeping tools, or “we’ll clean it up at month-end.” DEAGLE makes most of your accounting work complete in one shot by closing that gap. It automatically turns the operational data you already manage—loads, dispatches, invoices, payments, payroll, expenses—into structured, auditable accounting records.
Double-entry accounting is the system used by serious accounting software because it enforces a consistent financial record for every transaction. This means that the Credits & Debits for every transaction are tracked correctly in an auditable way. Having a true accounting backbone opens the door for tons of other features that, historically, only bookkeeping applications could provide.
In Diesel TMS, when something happens financially (you invoice a customer, pay a vendor, run payroll, record a fuel purchase), it will automatically be reflected the way accountants expect:
• It hits the right accounts (in your Chart of Accounts) with the right types.
• It shows up in the General Ledger
• It rolls up cleanly into your Income Statement and Balance Sheet
• It leaves a trail you can review later
• Credits & Debits must match
• In short: less guesswork, fewer “mystery numbers,” and reporting designed specifically for Transportation, with little-to-no extra work.
Set up and maintain a Chart of Accounts that matches your business. Organize income, expense, asset, liability, and equity accounts so reporting stays consistent as you grow.
Your General Ledger is the source of truth for accounting. Diesel TMS provides a clear ledger view of account activity and balances, so you can see exactly where numbers are coming from—and verify them.
Revenue and expenses over time.
Assets, liabilities, and equity—your financial position at a point in time. These reports help you understand profitability, cash pressure, debt load, and operational efficiency without waiting for someone to “export it and fix it.”
Not everything fits a template. Diesel TMS supports Journal Entries so you can handle adjustments, corrections, accruals, and edge cases while maintaining clean books.
Want a simple, chronological record of what happened? The Transaction Journal gives you a searchable timeline of financial activity—useful for reconciliation, month-end reviews, and answering “what changed?” quickly.
Cash flow is a daily concern in transportation. Diesel TMS includes Aging Reports so you can immediately see:
• What customers owe you (AR aging)
• What you owe vendors (AP aging)
• What’s current vs overdue (so collections and payment planning are easier)
Diesel TMS also supports Multi-Currency, Exchange Rates, as well as Taxes (like GST/HST). So, if you do a lot Cross-Border shipments, you should definitely try this.
Diesel TMS includes a Payroll Feature to help streamline one of the most important (and usually most time-consuming) accounting workflows in trucking. In Diesel TMS, your payroll activity is automatically consistent with your accounting books and reporting. Taxes shouldn’t surprise you. Diesel TMS includes Income & Payroll Tax Estimation to help you plan ahead using your real financial activity—so quarterly planning and year-end readiness get easier.
Diesel TMS can generate ACH files for electronic payments, giving you a practical way to pay securely, reliably, and without expensive payment add-ons.
Diesel TMS also supports Check Printing and the ability to customize the check layout.
Diesel TMS Accounting is designed to be approachable—even if you don’t have a degree.
• Create or review your Chart of Accounts (Defaults will be created automatically as needed.)

Always have a certified accountant review your records.
