The Six Line Items That Make Up the Stack
A solar sales org running its own in-house team is not paying for one platform. It is paying for a stack, and each piece has its own published 2026 pricing. Design and proposal software: Aurora Solar’s Premium tier runs $259 per user per month, adding LiDAR-assisted modeling and battery storage modeling on top of its $159 per user per month Basic tier, while OpenSolar operates as fully free with no paid tiers at all. E-signature: DocuSign’s Business Pro tier, the one built for sending contracts at volume with payment collection and bulk sending, runs $45 per user per month billed annually. A dialer: Readymode’s iQ tier, recommended for teams of five or more licenses, runs $299 per license per month. Canvassing and territory mapping: SalesRabbit’s Pro tier runs $49 per user per month billed annually, or $75 billed monthly. Workflow automation: Zapier’s Team plan, the tier needed for shared, org-wide automations rather than one person’s individual account, starts at $103.50 per month for 2,000 tasks. And local-presence phone numbers: Twilio prices a local US number at $1.15 per month, plus usage charges for calls and texts on top of that base cost.
Where the Total Swings the Most
Adding the per-rep line items together (design, e-signature, dialer, and canvassing) puts a single rep’s monthly software cost at roughly $349 on the free-design-tool path (e-signature $45, plus dialer $299, plus canvassing $49, plus $0 design) up to $632 on the premium-design-tool path (design $259, plus e-signature $45, plus dialer $299, plus canvassing $75 at monthly billing). Automation and phone-number costs sit on top of that as org-wide, not per-rep, expenses: a shared Zapier Team plan starting at $103.50 a month, and Twilio’s $1.15 per number plus metered usage that scales with actual call and text volume.
The design-software line alone accounts for nearly the entire gap between those two totals. Aurora’s Premium tier costs almost as much per rep as the e-signature, dialer, and canvassing line items combined, while OpenSolar’s free model removes that line entirely. That is the first decision worth making deliberately, not defaulting into, before pricing out the rest of the stack.
What a Fully Tooled Org Pays, Line by Line
| Line item | 2026 published rate | Billed |
|---|---|---|
| Design software (Aurora Premium or OpenSolar) | $259/user/mo or $0 | Per rep |
| E-signature (DocuSign Business Pro) | $45/user/mo | Per rep, annual |
| Dialer (Readymode iQ) | $299/license/mo | Per rep |
| Canvassing (SalesRabbit Pro) | $49 to $75/user/mo | Per rep |
| Automation (Zapier Team, 2,000 tasks) | From $103.50/mo | Org-wide |
| Local-presence numbers (Twilio) | $1.15/number/mo plus usage | Org-wide, scales with volume |
This is an assembled model built from each vendor’s own published pricing, not a single reported total-cost-of-ownership figure from one source, and the automation and phone-number lines will move with appointment and outreach volume rather than staying fixed the way the per-rep tools mostly do. A rep who bundles contract paperwork into fewer DocuSign envelopes, or a canvassing team that stays on SalesRabbit’s annual Pro rate instead of monthly, can meaningfully change the total without switching vendors at all.
