We have been using “Oci (SAM) Accounting System” in our construction business for over 10 years now, and it is proven to be incredibly useful, especially when it comes to separating costs by job. It’s easy to generate reports by project, which is essential for accurate costing and forecasting.
I would definitely recommend it to others looking for a reliable accounting solution with strong project/Job tracking features.
I expect the software could be improved by offering a clearer way to distinguish between active (ongoing) jobs and completed (non-active) jobs.
(A simple filter or summary view would make it much easier to manage, thanks.)

So far, everything looks good. Just a small suggestion: if the existing description is accidentally deleted while editing a quotation, there should be a way to retrieve it before the update is finalized. This would save the trouble of having to retype the entire description.
