Contractor brief from Centurion
There were a few constraints that shaped the work. The business could not afford a long shutdown because jobs were already on site and cash flow depended on regular invoicing. Data was split between a legacy accounting package, spreadsheets on shared drives and paper job notes from site supervisors. Load-shedding also meant the team needed a sensible process for saving work often and avoiding lost updates when power dropped.
We also had to keep the system simple enough for supervisors working away from the office. They needed clear screens, fewer fields, and a process that could be followed quickly on a phone or laptop without slowing down a busy day. For a contractor, if the admin flow takes too long, people stop using it.
- Legacy data cleaned before migration
- Process kept short for site and office staff
- Access planning considered intermittent power and mobile use
- Reporting needed to support job margin checks and invoicing runs
What we supplied and configured
Bizmatics put together a tailored ERP setup with the core modules the business actually used day to day. We mapped the order of work from enquiry to quotation, then from approved job to scheduling, procurement, delivery tracking and invoice creation. The aim was to reduce duplicate capture and give management one view of each contract.
We configured workflow steps so that a job could not move forward without the key details being captured, such as site address, labour allocation, materials required and billing terms. Custom reports were added for outstanding work, aged debtors, job profitability and supervisor activity. Where the contractor had existing tools that still had value, we planned the integration so those systems could pass data through cleanly instead of forcing a full replacement.
- ERP implementation with job and finance alignment
- Process mapping for quoting, scheduling and invoicing
- Data migration from spreadsheets and older records
- Custom reporting for margins, WIP and debtor control
- System integration for existing operational tools
Rollout in six weeks
The project ran over six weeks from discovery to go-live support. Week one covered process mapping with the owner, ops lead and finance team. Week two was focused on cleaning data and agreeing on what should be brought across. Weeks three and four were used for configuration, report building and integration checks. Week five handled user testing and training. Week six was go-live with close support from our side.
Because contractor work does not stop for software projects, we staged the rollout in a way that did not interrupt active jobs. The team started with core quoting and invoicing, then adopted the scheduling and reporting pieces as confidence grew. That practical sequence made the change easier for everyone.
- Week 1: discovery and process mapping
- Week 2: data review and migration planning
- Weeks 3 to 4: configuration and report setup
- Week 5: testing, training and user sign-off
- Week 6: go-live support and issue resolution
Results for the operations and finance teams
Once the new process was in place, the business had a much clearer line of sight from quote to cash. Supervisors could see what was booked, what was in progress and what still needed to be invoiced. The finance team spent less time chasing missing job details, and management could compare planned cost against actuals before the month was closed.
There was also a noticeable improvement in accountability. Because the same record followed the job through the system, fewer details got lost between departments. The owner could review margins by job type, identify repeat issues in the quoting process and make decisions on staffing with better numbers in front of him.
- Faster invoice preparation at month end
- Better control over job costing and margin checks
- Clearer scheduling for crews and vehicles
- Less double entry between office and field teams
- Improved visibility for management decisions
What we would repeat on the next contractor rollout
The biggest lesson was to keep the process practical from the start. Contractors do not need extra admin, they need fewer handovers and better information at the right time. We would use the same approach again: map the real workflow first, clean the data properly, then phase the rollout so the team can settle into it without pressure.
We would also keep the training short and task-based. In this project, that meant showing staff exactly how to create a job, update progress, trigger billing and pull a report. That approach worked because it matched the way the business already operated, only now the information sat in one place and did not disappear between departments.
- Start with the real workflow, not a theory of how it should work
- Keep field and office screens simple
- Train users on live tasks rather than generic features
- Phase the change so invoicing and scheduling stay on track
