Starting With the Right Software Matters

Abio manages complex, fully unionized, Canadian payroll.  Union deductions and remittances are generated automatically with each payroll. Abio also recognizes interprovincial nuances surrounding things like WCB remittances. Most importantly, it scales to very large jobs. So you won’t be finding yourself fighting with unwieldy business practices that were only manageable when you had fewer people on payroll.

Job Costing

Job Costing

Payroll, Purchasing, Equipment, and Receivables are all tracked by the cost centre they are posted to. Sophisticated reports let you know exactly how much time and effort you are spending on each aspect of your project.



Easily process your payroll, even when employees work for more than one union or in more than one job description. Abio organizes your remittances by how many hours an employee worked in each union.



Manage your purchases, from requisitions to purchase orders to receiving to invoices to payments.

Save documents at each step to demonstrate to your clients how materials were acquired.  No more searching your filing system!



Our Time & Materials billing lets you collect your expenses and apply markups.

Once the billing package is complete, generate an invoice with supporting documents.

Field supervisors can upload signatures and documents on site.
