Choose Solo for:
Proposal-to-Contract Rail
Institutional Verdict
Institutional Choice
Stage 2-3 sales teams wanting proposal speed without LiDAR-accuracy trade-offs. Primary Stage 2 (Integrated): The industry benchmark for sales-to-contract velocity. It eliminates the 48-hour engineering bottleneck by combining LiDAR-accurate proposals with on-demand design-as-a-service (DaaS).
Strategic Fit: Proposal-to-Contract Rail acting as a high-velocity point solution for single-task efficiency to reduce friction in the top-of-funnel or specific workflows.
The Strategy
Solo dominates the proposal-to-contract rail by combining LiDAR-accurate models with on-demand human engineering fulfillment, eliminating the 48-hour design bottleneck. However, because you are relying on a human-in-the-loop CAD queue, your field reps will occasionally absorb the manual administrative overhead of apologizing to homeowners while waiting for fulfillment turn-around during peak weekend hours.
Integration: Best paired with GoodLeap (Finance) for an unmatched Stage 2 residential closing engine.
Choose Sunbase for:
Consolidated Operational Suite
Institutional Verdict
Operations-First Pivot
Pivot to Sunbase for a more operations-heavy experience that prioritizes backend inventory and installer-speed over front-end design.
Strategic Fit: CRM tool evaluated on its speed-to-market and high user adoption rate for growing residential teams, prioritizing consensus over heavy API federation.
The Strategy
Sunbase dominates the mid-market operational space by unifying lead generation, design, inventory, and HR into a single connected platform. However, because its design engine lacks the LIDAR-backed fidelity of Aurora, your sales reps will absorb significant manual administrative overhead performing manual site surveys and correcting production estimates to ensure the pro-forma matches the real-world install.
Integration: Best paired with GoodLeap (Finance) for a consolidated Stage 3 residential stack.

Side-by-Side Matchup
Direct qualitative benchmarking of Technical Red Flags and Maturity Walls.
The Technical Ceiling
SYSTEM CONSTRAINT Solo
› API access for high-volume CRM sync is strictly gated by usage-based pricing and often requires custom partner-key authorization.
› This means automating the data flow from Solo into your backend project management tool (like JobNimbus) is an expensive, high-friction integration rather than a native capability.
Sunbase
› The integrated CRM-to-Ops sync requires absolute, manual Attribute-Parity.
› If your lead metadata isn't perfectly mapped to your project fields during the conversion process, the system will trigger a Data-Dropout that siloes your technical specs, forcing your office staff to manually re-enter project details just to generate a work order.
The Maturity Wall
SCALABILITY LIMIT Solo
› The financial structure creates a dangerous linear scaling trap.
› The combined $150/month base plus the $15-$25 per-proposal fee heavily penalizes canvassing teams that generate high top-of-funnel volume.
Sunbase ✦
› The primary scaling wall is Module Bloat.
› While having HR and inventory in the same tool is powerful, it creates massive operational drag during the onboarding phase.
The Deep-Dive Audit
TECHNICAL DEPTH Solo ✦
› Do not deploy Solo if you run a high-volume, low-conversion canvassing operation or if your firm focuses on complex commercial projects.
› The proposal engine is specifically tuned for residential closing speed; throwing complex C&I edge-cases at the fulfillment team will break your sales flow and result in rejected engineering sets.
Sunbase
› Do not deploy Sunbase if your business model relies on a high-fidelity Sales-Bro proposal aesthetic or complex enterprise API federation.
› The platform is an industrial-grade, unified ERP; its dated UI and rigid Attribute-Parity requirements will break your sales velocity if your team isn't ready for a disciplined, 8-week migration into a single-tool ecosystem.

Lumen Economic Verdict
Verified 2026 Audit
Lumen Audit Note
The Priority Trap. Standard turnarounds are 24-48h; Instant designs require a $15 surcharge per unit. Speed is a variable tax on your per-project margins.
Operational Impact
Proposal Velocity. Eliminates the need for in-house design staff, allowing reps to request and receive high-fidelity proposals while the lead is still warm.
Hard Margin Benefit
Fixed Cost Reduction. Converts your design department from a fixed monthly salary-drain into a variable cost that only scales when you are actually closing deals.

Lumen Audit Note
The Inventory Tax. Unlike pure CRMs, Sunbase requires intensive setup for warehouse and physical procurement logic, adding 3-5 weeks to your initial ROI timeline.
Operational Impact
Directly impacts Stage 4 (Fulfillment) velocity. By centralizing physical asset tracking, it eliminates the Parts-Wait bottleneck that kills residential install margins.
Hard Margin Benefit
Physical Asset Protection. Minimizes Truck Roll waste and inventory shrinkage, which accounts for 2-5% of annual net-revenue loss in un-automated EPCs.
