Comparison · Solar EPC Software
For solar EPCs, installers and dealers
We are biased - read both sides
Our verdict: OneSolar CRM for solar companies, JobNimbus for general contractors
If your primary business is solar installation, EPC or dealing - OneSolar CRM has BOQ, inventory, vendor management and milestone invoicing that JobNimbus lacks entirely. If you do roofing and solar as a secondary business, JobNimbus may serve you adequately.

The fundamental difference
No BOQ module
JobNimbus has no Bill of Quantities functionality. Solar companies build BOQs in Excel, manage them externally and manually re-enter data. OneSolar CRM auto-generates the BOQ from system size using your product catalogue - and links it to inventory, procurement and invoicing.
No inventory management
JobNimbus has no inventory module. Solar dealers and EPCs managing panels, inverters and BOS components cannot track stock, reserve materials per project or flag shortfalls. This forces a parallel inventory system outside JobNimbus.
No vendor management
JobNimbus has no vendor procurement module. Solar companies managing supplier relationships, purchase orders, delivery tracking and vendor payments do this entirely outside JobNimbus - typically in email and spreadsheets.
No automatic milestone billing
JobNimbus requires manual invoice creation. OneSolar CRM auto-creates the invoice when a milestone is marked complete - billing is never missed, never delayed and never dependent on someone remembering.
USA-focused, limited global support
JobNimbus is built primarily for the USA residential market. Solar companies in the UAE, India, Australia, Europe and GCC find limited support for local tax structures, multi-currency invoicing and regional compliance.
No HRMS or geo attendance
JobNimbus has no HRMS. Solar companies with field installation crews cannot track attendance with GPS verification or manage field workforce productivity without a separate tool.
Reasons solar companies switch
What JobNimbus users tell us before switching
We build BOQs in Excel and copy everything into JobNimbus manually - it is double the work
OneSolar CRM auto-generates BOQ from system size. Product catalogue, quantities, pricing and approval - all in one place. Zero re-entry.
Our inventory is a mess - we have no idea what stock we have until a project starts and something is missing
Real-time multi-warehouse inventory. BOQ-linked stock reservation before every project. Shortfall alerts before it becomes a problem.
We miss milestone invoices constantly - projects finish and nobody raised the billing
Milestone completion in OneSolar CRM automatically creates the client invoice. No manual trigger. No missed billing. Finance notified instantly.
JobNimbus is built for roofing - half the features do not apply to solar and the ones we need are not there
OneSolar CRM is built exclusively for solar - every module designed around how solar EPCs, installers and dealers actually operate.
