Key Takeaways

  • An OMS tracks solar projects from signed contract through installation, inspection, and interconnection
  • Automates handoffs between sales, design, permitting, procurement, and installation teams
  • Reduces project cycle time by eliminating manual status tracking and communication gaps
  • Integrates with CRM, design tools, and accounting software for end-to-end visibility
  • Critical for installers processing more than 10–15 projects per month
  • Tracks equipment inventory, crew scheduling, permit status, and inspection results in one system

What Is an Order Management System?

An order management system (OMS) in the solar industry is a software platform that manages the complete lifecycle of a solar project — from the moment a customer signs a contract through equipment procurement, permitting, installation, inspection, and utility interconnection. It provides a single source of truth for every stakeholder involved in delivering a solar installation.

For solar companies handling multiple projects simultaneously, manual tracking through spreadsheets and email chains breaks down quickly. An OMS replaces this fragmented approach with structured workflows, automated notifications, and real-time status visibility across the organization.

The average residential solar installation involves 15–25 discrete tasks across 5–8 different team members over 45–90 days. Without an OMS, projects stall at handoff points — design waits for site survey data, procurement waits for design approval, installation waits for permits. Each delay costs money and erodes customer satisfaction.

How an Order Management System Works

A solar OMS manages the sequential and parallel tasks required to complete an installation:

1

Contract Signed → Project Created

When the customer signs, the OMS automatically creates a project record with all contract details, customer information, and system specifications from the proposal.

2

Site Survey and Design

The OMS assigns the site survey task, tracks completion, and triggers the design phase. Design files from solar design software are attached to the project record.

3

Permitting

Permit applications are tracked with submission dates, expected approval timelines, and status updates. The OMS flags overdue permits and notifies the responsible team member.

4

Equipment Procurement

The system generates purchase orders based on the approved design, tracks inventory availability, and manages delivery schedules to align with the installation date.

5

Installation Scheduling

Once permits are approved and equipment is available, the OMS schedules the installation crew, assigns the work order, and sends customer notifications.

6

Inspection and Interconnection

Post-installation, the OMS tracks inspection scheduling, results, utility interconnection applications, and final system commissioning. The project closes when the system is producing.

Types of Solar OMS Solutions

Different OMS approaches serve different business sizes and needs:

Small Installers

CRM with Project Tracking

Platforms like HubSpot or Salesforce with custom project tracking fields. Works for companies doing under 15 projects per month. Limited automation but familiar interface.

Mid-Market

Solar-Specific OMS

Purpose-built platforms like Scoop Solar, PVComplete, or Solo. Designed specifically for solar workflows with pre-built stages, task templates, and industry-specific integrations.

Enterprise

Custom ERP Integration

Large installers often build custom OMS functionality into enterprise resource planning (ERP) systems like NetSuite or SAP. Handles high volume but requires significant implementation investment.

Integrated

Design-to-Install Platforms

All-in-one platforms that combine design, proposals, and project management. SurgePV’s proposal workflow connects directly to downstream project execution, reducing duplicate data entry.

Designer’s Note

The most common OMS failure mode is tool fragmentation — different teams using different systems with no data flow between them. When your design tool, proposal software, and project management system are disconnected, every handoff requires manual data transfer. Look for platforms that integrate design-to-installation in a single workflow.

Key Metrics & Calculations

An OMS should track these operational metrics to identify bottlenecks and improve efficiency:

MetricTargetWhat It Measures
Average Cycle Time30–45 days (residential)Days from contract to commissioning
Permit Approval Time5–15 daysDays from submission to approval
Design Turnaround1–3 daysDays from site survey to completed design
Installation Completion Rate95%+Percentage of installations completed on first visit
Change Order RateUnder 5%Percentage of projects requiring design changes post-permit
Customer Touch Points5–8 maxNumber of required customer interactions per project

Practical Guidance

An OMS affects every team in a solar company. Here is role-specific guidance:

  • Integrate design output with the OMS. Ensure your solar design software exports system specifications, equipment lists, and single-line diagrams directly into the project record. This eliminates manual data transfer errors.
  • Standardize design deliverables. Define what constitutes a “completed design” in the OMS — layout, electrical design, structural calculations, and permit-ready drawings. This prevents the design stage from being prematurely marked complete.
  • Track revision history. Log all design changes within the OMS with timestamps and reasons. This creates an audit trail and helps identify systemic issues causing change orders.
  • Set realistic SLA targets. Commit to specific design turnaround times within the OMS. A 48-hour design SLA is achievable for residential projects with proper site survey data.
  • Define stage gates clearly. Each project stage should have explicit entry and exit criteria. A project should not move to “ready to install” unless permits are approved, equipment is on-site, and the customer has confirmed the date.
  • Automate routine notifications. Set up automated customer updates at each milestone — design complete, permit approved, installation scheduled, system commissioned. This reduces inbound customer calls by 40–60%.
  • Track bottleneck metrics weekly. Review which stages have the longest average duration. Permitting delays are often the biggest bottleneck — identify jurisdictions with slow turnaround and plan accordingly.
  • Manage equipment inventory proactively. Link procurement to the design approval stage so equipment orders are placed immediately. Waiting until permits are approved to order equipment adds weeks to the cycle.
  • Use OMS data to set customer expectations. When presenting proposals, share realistic installation timelines based on actual OMS data — not optimistic estimates. Under-promise and over-deliver.
  • Monitor post-sale project status. Access the OMS to check project progress before customer follow-ups. Nothing erodes trust faster than a sales rep who does not know the project status.
  • Feed proposal data directly into the OMS. When using solar proposal software, ensure signed proposals auto-populate the OMS project record with system specs, pricing, and financing terms.
  • Track referral triggers. Set OMS alerts at system commissioning to prompt referral requests. Satisfied customers at project completion are the highest-value referral source.

Real-World Examples

Small Installer: Spreadsheet to OMS Transition

A 5-person solar company in Georgia tracked projects using Google Sheets and email. At 8 projects per month, the system worked. When volume reached 15 projects per month, projects started falling through the cracks — permits expired because no one tracked renewal dates, equipment arrived before permits were approved, and customers complained about lack of updates. After implementing a solar-specific OMS, average cycle time dropped from 72 days to 48 days, and customer satisfaction scores increased by 30%.

Mid-Size Installer: Multi-State Operations

A regional installer operating across three states manages 60 projects per month. Each state has different permit requirements, inspection processes, and utility interconnection procedures. The OMS maintains separate workflow templates for each jurisdiction, automatically applying the correct checklist when a new project is created. This eliminated the compliance errors that previously caused 12% of projects to require re-submission.

National Installer: Full ERP Integration

A national solar company processing 500+ installations per month integrates its OMS with a custom ERP system. Sales data flows from CRM to OMS to procurement to accounting without manual intervention. Design files from solar software auto-populate permit packages. Crew scheduling optimizes based on geographic proximity and skill requirements. The system handles everything from customer credit checks to warranty registration.

Impact on Business Operations

Implementing an OMS transforms how solar companies operate:

Pro Tip

Do not customize your OMS until you have used the standard workflow for at least 50 projects. Most solar companies over-customize early, building complexity they do not need. Start with the default workflow, identify actual bottlenecks with data, then customize only the stages that consistently cause delays.

Frequently Asked Questions

What is an order management system in solar?

An order management system (OMS) in solar is software that tracks every project from the signed contract through installation and commissioning. It manages task assignments, permit tracking, equipment procurement, crew scheduling, and customer communications in a single platform. The goal is to eliminate the spreadsheets, emails, and manual handoffs that cause delays and errors as projects move through the installation pipeline.

When does a solar company need an OMS?

Most solar companies hit the OMS tipping point at 10–15 projects per month. Below that volume, spreadsheets and email can work. Above it, manual tracking leads to missed deadlines, permit expirations, customer communication gaps, and crew scheduling conflicts. If you find yourself asking “where is this project?” more than once a day, you need an OMS.

How does an OMS integrate with solar design software?

Integration typically works through APIs or file exports. When a design is completed in solar design software, the system specifications — panel count, inverter model, string configuration, and layout drawings — are transferred to the OMS project record. This data feeds into permit packages, equipment purchase orders, and installation work orders. The best platforms, like SurgePV, handle this connection natively so design data flows directly into project execution without manual re-entry.

What ROI can a solar company expect from implementing an OMS?

Companies typically see a 20–40% reduction in project cycle time, a 30–50% increase in projects per employee, and a significant drop in customer complaints and change orders. For a company doing 30 installations per month, reducing cycle time by 15 days translates to faster revenue recognition and lower carrying costs. The OMS subscription cost is usually recovered within the first two months through labor savings and reduced errors alone.
