Quickest sends 60-second solar proposals with built-in subsidy maths; Solar Spine manages the install, payments and operations after the sale.
In short
Quickest Solar CRM is a mobile-first, WhatsApp-native CRM and proposal generator built by Heaven Softech Pvt. Ltd. in Surat, Gujarat, founded in 2015 and rebuilt as a dedicated solar product in 2022. It is fundamentally a lead-capture, proposal and WhatsApp-follow-up sales tool with a solar-specific pipeline, not a full install or payments-operations platform. Roof design is sold separately (as SurgePV) and through paid professional services. Quickest reports 1,000+ Indian EPCs as customers, 85,000+ proposals sent, and 120 MW of pipeline tracked.
Quickest's core strength is post-proposal lead follow-up: rule-based WhatsApp drip sequences (no response in 24h → reminder, 72h → subsidy update, manager escalation if still no response), read-receipt tracking, automatic opt-out handling, and WhatsApp templates in 22 official Indian languages (proposal PDFs themselves generate in seven: English, Hindi, Gujarati, Marathi, Tamil, Telugu and Kannada). PM Surya Ghar subsidy data is auto-calculated and kept current within 24 hours of government announcements. The platform includes mobile-first site surveys (GPS, shading notes, roof photos captured on phone), 60-second PDF proposal generation, and a 363-post blog spanning buyer guides, cost guides and regulatory updates — a lead-gen moat.
An EPC choosing Quickest faces a hard stop once a deal wins. No operational backbone exists: no stage-gating on open checklists, no auto-created tasks with due dates on stage entry, no payment schedules or payment-gated material dispatch, no cheque-bounce handling, and no document verification gate. The AI Calling & Voice Follow-Up feature is announced but minimally detailed (one homepage tile, no dedicated page). Per-user, annual-only pricing with a 3-user minimum (₹20,997/year floor) is a poor fit for seasonal or contract crews.
Where Quickest wins
- Quickest's WhatsApp integration is genuinely native, not bolted on: time-triggered drip sequences (24 hours, 72 hours, manager escalation), read-receipt tracking, automatic opt-out handling, and WhatsApp templates in 22 official Indian languages.
- PM Surya Ghar subsidy calculation is auto-updated within 24 hours of government announcements, eliminating manual subsidy maths from every quote.
- Site survey capture on mobile (GPS, roof photos, shading notes) enables 60-second PDF proposal generation without requiring a design tool upstream.
- A 363-post blog updated weekly, a 100-country comparison hub, and a free public subsidy calculator embed a lead-generation moat that took years to build.
Where Solar Spine wins
- Solar Spine owns the full deal-to-operations lifecycle once a proposal is won: stage-gating on open checklist items forces discipline into each phase, and auto-created tasks carry due dates forward and escalate overdue work up the org chart nightly.
- Instalment schedules (10/70/20 or custom) are tracked per project, with payment thresholds that prevent material dispatch until collections clear — a payment gate Quickest lacks entirely.
- Document verification (ops marks each identity document correct or incorrect, and an incorrect file returns to the person who photographed it) gates progress, so incomplete KYC cannot advance a project — a check Quickest does not have.
- Flat monthly or annual pricing with unlimited users makes sense for a rooftop EPC whose site crews, telecallers, and admin staff may be seasonal or contract — there is no per-user seat minimum.
- Ask the Business (director and GM only) answers live questions like 'how much cash is due this week' or 'which projects are 30 days-plus in install' from the database, without needing a data analyst.
Best for
Quickest suits rooftop solar teams (3–25 people) closing 5–30 deals per month who prioritise fast, WhatsApp-native proposal generation and subsidy pre-calculation over post-sale operations tracking.
Not for
Quickest lacks install-phase operations (payment schedules, document gates, task escalation); Solar Spine has no roof design or shading tools.

Solar Spine
Solar Spine price list, the same numbers Razorpay charges
Feature by feature
| Capability | Quickest | Solar Spine |
|---|---|---|
| Solar-specific | ||
| Solar sales and install stages out of the box | Yes. 7-stage named solar pipeline (Enquiry, Survey, Quotation, Subsidy, Net metering, Installation, Operations and maintenance); a shorter 6-stage variant also appears as the default. | Yes. 7 sales stages and 17 project stages seeded on day one, all editable. |
| Stage checklists that change with loan, subsidy and DISCOM | No. No per-stage task checklist feature is described. | Yes. 57 checklist items; loan, subsidy and DISCOM-specific tasks appear only where they apply. |
| DISCOM net-metering steps tracked | Partly. Net metering is a named pipeline stage and DISCOM tariff library is used for quote calculation, but no specific tracked steps or sub-tasks are documented. | Yes. Net-meter paperwork branches for BRPL, BYPL, TPDDL, PVVNL, NPCL, DHBVN and UHBVN. |
| PM Surya Ghar and subsidy tracking | Yes. Dedicated pipeline stage plus automatic subsidy-calculation engine; subsidy data is updated within 24 hours of government announcements. | Yes. PMSG submission, DCR certificate, GBI and central subsidy redemption as dated tasks. |
| kW as a native field with kW reporting | Yes. kW is the native unit throughout proposals, the subsidy calculator, and reporting rolls up to MW. | Yes. Every deal and project carries capacity; dashboards and targets report in kW. |
| Roof design, shading and proposal generation | Partly. Fast branded PDF proposal generation (under a minute, auto subsidy calc, white-label) is a core feature. Roof design and shading are explicitly not part of the CRM — sold separately as SurgePV and as paid professional services. | No. Solar Spine does not do roof design. Use a design tool and track the job here. |
| Execution | ||
| Tasks written automatically with due dates when a stage opens | No. Users manually set reminder dates and times for leads; follow-ups are user-scheduled, not auto-generated when a stage opens. | Yes. Nobody types the checklist; each task carries the date it was given when the stage opened. |
| Overdue work escalates up the org chart on its own | Yes. WhatsApp Follow-Up feature documents a time-based escalation: if no response in 24 hours, reminder; if no response in 72 hours, subsidy update; if still no response, notify manager. | Yes. Every night a late task climbs one rung and keeps climbing until someone acts. |
| A stage cannot be advanced with open checklist items | No. Stages are freely drag-and-drop; no blocking on open checklist items. | Yes. The advance button is unavailable until the stage's items are closed. |
| Documents verified by ops before work proceeds | No. No document-upload-gates-progress mechanism is described. | Yes. A document is done when ops marks it correct; a rejection goes back to the person who photographed it. |
| A different first screen per role | Partly. Each sales rep gets an individual performance dashboard; Enterprise adds role-based access control, but no evidence of distinct role-type first screens (owner vs ops vs telecaller). | Yes. Nine roles, nine first screens, from telecaller to director. |
| Field use on a phone: photos, tasks, call outcomes | Yes. Native iOS and Android apps with offline lead capture, on-site survey capture (roof area, shading notes, meter details, GPS-tagged photos), and 60-second mobile proposal generation. | Yes. Every screen works on a phone; documents are photographed at the customer's house. |
| Money | ||
| Instalment schedule per project | No. No instalment or payment-schedule tracking (e.g. 10/70/20) is mentioned. | Yes. 10/70/20 or whatever you agreed, with due dates and outstanding balance visible to all. |
| Material cannot dispatch until payment is collected | No. No payment-collected-before-dispatch gate is described. | Yes. Thresholds per stage, set by the workspace; the default is the one the first customer ran. |
| Daily overdue payment alerts to owner and manager | No. No payment-specific overdue alerting exists; only a generic deal-inactivity nudge is described. | Yes. 7 am every day, to the person who owns the collection and their manager. |
| A bounced cheque reopens the instalment | No. Cheque-bounce handling or instalment reopening is not mentioned. | Yes. Yes |
| GST invoices and quotes from the same record | Yes. Solar goods at 5 percent GST applied automatically on quotes; GST tax invoices with HSN codes supported for the EPC's own customer billing. | Yes. Invoice creation is a stage in the pipeline; the subscription itself is GST-invoiced too. |
| Leads and calling | ||
| Meta lead ads land in the system within minutes | Partly. Facebook and Meta Lead Ads supported via Pabbly (third-party relay), not native; no speed claim published. | Yes. Ad leads arrive marked hot at the top of the calling queue inside five minutes. |
| PIN-code check on incoming leads | No. PIN-code or serviceability checking on incoming leads is not mentioned. | Yes. Leads outside the PIN codes you serve are kept out of the AI caller's queue. |
| AI caller that qualifies leads and books visits | Partly. AI Calling and Voice Follow-Up is marketed as a feature but exists only as a single homepage tile with one line of copy; no dedicated page or depth on qualification, visit booking, or outcome capture. | Yes. Optional. Calls 9 am to 9 pm IST, books the visit on a named salesperson's day, hands off with notes. |
| Built-in telecalling queue with daily batches and outcomes | No. No built-in telecalling queue with daily batches and outcomes is described. | Yes. Queues built and ordered before the caller sits down; one outcome vocabulary for humans and the AI. |
| Lead outcomes written back to Meta | No. Meta and Facebook conversion-outcome writeback for ad optimisation is not discussed. | Yes. Qualified, converted and disqualified statuses flow back through the lead sheet into Meta's Conversions API, so the account optimises for buyers, not form-fillers. |
| WhatsApp messaging and automation | Yes. Core differentiator: rule-based drip automation, read receipts, automatic opt-out handling, proposal delivery, and WhatsApp Business API in 22 languages. | Partly. Click-to-chat and logged WhatsApp interactions. No automated messaging. |
| Reporting | ||
| Owner dashboard: kW against target, cash due, stuck projects | Partly. Real-time dashboards cover revenue, conversion rate, pipeline value, deal velocity, lead-source ROI, and MW pipeline, but the specific framing (kW vs target, cash due, stuck projects) is not confirmed. | Yes. Yes |
| Per-person monthly targets and attainment | No. Per-person monthly targets and attainment tracking is not mentioned. | Yes. Yes |
| Ask the business a question in plain English | No. AI question-answering or natural-language data exploration is not referenced. | Yes. Director and GM only. Finding, evidence, table, caveat, next step, from live data. |
| One-click export of everything | Yes. Export reports as PDF or Excel with one click; CSV export of lead and deal data is explicitly promised. | Yes. Excel export any time. No lock-in. |
| Data | ||
| Data hosted in India | Yes. Primary infrastructure on AWS, Mumbai (ap-south-1); customer pipeline data stays in India. | Yes. Postgres in Mumbai (ap-south-1); documents in a private store. |
| Tenant isolation at the database level | Yes. Workload isolation per tenant; database row-level scoping by account. | Yes. Row-level security fences every workspace; identity documents are visible only to the project chain. |
| Pricing and support | ||
| Pricing model | No. Per-user subscription with a hard 3-user minimum, not flat-per-company; the opposite of Solar Spine's model. | Yes. Flat per company: ₹10,000 a month or ₹99,999 a year plus GST. Unlimited users. |
| Prices published in INR | Yes. All published prices are native INR (₹0, ₹6,999 per user per year). | Yes. Yes |
| Free trial without a card | Yes. Free plan: 10 proposals per month, no credit card, no setup — note this is a permanent free tier (freemium), not a time-boxed trial. | Yes. 30 days, no card, no call. |
| Setup or onboarding fee | No. No setup or onboarding fee is mentioned; FAQ emphasises sub-10-minute self-serve setup. | Yes. None. Send the filled setup form and the workspace configures itself. |
| India-based support in IST | Yes. Surat-based team; support hours Mon–Sat, 10 AM–7 PM IST; WhatsApp support with approximately 1-hour reply target; English, Hindi, and Gujarati. | Yes. Email, replies within one business day, from Mumbai. |
Switching from Quickest
- Export from Quickest: CSV-export your leads and deals (Quickest explicitly promises 'Your data is yours, you can export it anytime').
- Map Quickest's stage names (Enquiry, Survey, Quotation, Subsidy, Net metering, Installation, O&M) to Solar Spine's 7 solar sales stages — the overlap is close enough to import as a first pass.
- Rebuild your WhatsApp templates and follow-up sequences in Solar Spine from scratch, since Quickest's automation state, read-tracking, and opt-out lists are not portable.
- Re-enter any dealer and channel-partner structure manually — Quickest's Dealer Management feature has no direct export schema.
- Populate your payment-schedule thresholds (default: 25 percent before structure dispatch, 65 percent loan or 95 percent non-loan before material, 100 percent before net meter) and define your document-gate rules.
Questions people ask
Can I use both Quickest and Solar Spine together?
You can, but they remain separate systems. You would export proposals from Quickest and re-enter them as deals in Solar Spine, which defeats the point. Most teams migrate fully to Solar Spine and use a design tool separately if they need roof layouts.
Does Solar Spine replace the design tool Quickest uses?
No. Solar Spine handles sales, operations, and payments for an EPC; it does not draw roof layouts or calculate shading, and has no plans to. Pair it with SurgePV, Helioscope, Aurora, or another design tool the way you would with Quickest today. What changes is everything after the design is done: the proposal, the payment schedule, the document checks, and the install itself all move into Solar Spine's stages once the deal is won.
Which is cheaper for a 12-person team?
Quickest charges ₹6,999 per user per year with a 3-user minimum, totalling ₹20,997 per year for the floor and scaling per seat. For 12 users, that is ₹83,988 per year. Solar Spine charges a flat ₹10,000 per month (₹120,000 per year) or ₹99,999 per year, both plus 18 percent GST, with unlimited users. For 12 people, Solar Spine's annual plan at ₹99,999 is a better deal, and you have no per-user seat pressure.
Can I export my Quickest data to Solar Spine?
Leads and deals export as CSV; reports export as Excel. Map Quickest's stage names to Solar Spine's stage set and import the CSV into the calling queue and customer records. Quickest's WhatsApp automation state, read-tracking, and opt-out history do not export, so you will rebuild follow-up sequences from scratch in Solar Spine.
Where is Quickest's data hosted?
AWS Mumbai (ap-south-1); Quickest's security page states that customer pipeline data stays in India, isolated per tenant with database row-level scoping by account. Solar Spine also runs its database in Mumbai (ap-south-1), with row-level security fencing every workspace, so both meet India data-residency expectations for a solar EPC. Neither publishes a data-processing agreement template on its public site, so ask directly if your funding partner or DISCOM requires one before signing.
Is there an integration between them?
Not today. Quickest exports leads and deals as CSV and reports as Excel; Solar Spine imports CSV from any source, so a one-time move is straightforward. A direct, ongoing API link between the two is not published by either vendor, so running them side by side means re-entering or re-importing data by hand rather than a live sync. Most EPCs treat this as a one-way migration rather than a permanent pairing.
