Change Order Management

The Change Order Management module tracks requests-for-information (RFIs) from inception through approval to ensure that money is never left on the table. Creating and monitoring potential changes to the scope of work couldn’t be easier. And when change orders are created, the Change Order Management module automatically updates the estimate, progress billing and subcontract if applicable.

Equipment Management

Managing your equipment is key to managing your business. In the Equipment Management module, every piece of equipment is considered a profit center. You can manage up to seven different rate levels for charging equipment to jobs and work orders, and sophisticated depreciation calculations and maintenance scheduling reporting, you gain a better understanding of the true cost of each piece of equipment while simplifying own, rent or lease decisions.

Integration between the Equipment Management and Payroll modules eliminates duplicate data entry when accounting for operator time.

Fixed Assets

The Jonas Fixed Assets module allows you to closely monitor the location and value of your fixed assets and simplifies the management of depreciation and amortization. Track assets by category and location with related purchase and selling prices, and calculate depreciation with automatic monthly journal entries using a variety of rates and methods.

General Ledger

The Jonas General Ledger is fully GAAP compliant and designed specifically for contractors, the General Ledger module is both powerful and easy to use. Open accounting period flexibility allows you to work in the current period (month, quarter, year, etc.) while the previous period is still open. User-level security clearly defines who can post transactions to any given period, and multi-company accounting automatically completes routine inter-company transactions.


The Jonas Inventory module provides a way to track and cost parts and other materials. Inventory can be charged to jobs and work orders directly through the Inventory module, or from the Job Cost and Service modules.

Job Cost

Now you have all the tools you need to manage your projects from the beginning bid through completion. The Jonas Job Cost application manages all aspects of project administration through a single screen.

Buyer Beware…System is not user friendly. You will have to hire more employees for the same amount of work as the system is not effecient.

The Good…

Service Dispatch Board

The Bad…

Everything!! Not user friendly. Not efficient. Takes 3 times as long to do a simple task like billing a customer.

Payroll in Jonas is horrible. You can create your own reports but you have to pick the data from a small list of data, not the data you need. Vacation if accrued by anniversary date has big problems. Data for an employee is in pieces all over the place. Deductions require an ongoing life balance (2017 deduction must be added to 2019 balances) and doesn’t show how much is remaining on the deduction. Group agreements for fringe cost has required me to setup one for each employee, during open enrollment this will take hours to change before doing payroll. Lots of other problems, their accounting department uses Great Plains software.

The Good…

I like the job cost part of the program so far. Fairly easy to use.

The Bad…

Payroll & A/P

The solution is just getting old from a functionality stand point. It’s really hard for me to get any reporting or data out of the solution

I’ve been using Jonas since 2008. We had a canned solution. It was a moderate accounting system but we used it a lot. There was no intergration between accounting and job costing. When we closed at the first year, we thought we could just put it in the computer and everything would come out. Come December 31st, it was a mess because job costing and accounting were not matching up. We ended up having to close on a monthly basis and it was a nightmare trying to close and match up job costing and accounting.

Going with Jonas, they have integration so the two are locked at the hip. We’d rarely go off between accounting and job costing. They are always matched. The project managers now are working with real-time data and can recover costs quickly.
