Free Solar CRM Software: What ₹0 Plans Actually Cover

₹0 is a subscription price, not an operating model. A free customer relationship management system can still require paid messaging, connector work, data cleaning, administration, and an urgent migration later.

Solar teams add another difficulty. A generic deal pipeline may track leads well but know nothing about site surveys, system size, subsidy assumptions, technical quotations, approvals, installation, or service.

This comparison uses official plan pages accessed on 10 August 2026. It ranks fit by use case after pass and fail gates. It does not treat trials as free plans.

In this guide:

• A dated method that separates free plans from trials
• Solar-specific, generic, one-app, no-code, spreadsheet, and self-hosted options
• Current users, contacts, storage, pipeline, API, and proposal limits
• WhatsApp, email, telephony, integrations, and automation checks
• Security, administration, audit, export, backup, and support gates
• Implementation, migration, administration, upgrade, and exit costs
• A pilot scorecard and procurement checklist

Methodology: How We Evaluated Free Solar CRM Software

The method was fixed before the product order. It asks whether the free option can operate a defined workflow safely, not which vendor publishes the longest feature list.

Evidence was limited to current official pricing, product, help, or documentation pages. We did not use marketplace summaries, reseller claims, or old screenshots for plan limits.

Pass Gates

An option had to pass these gates on 10 August 2026:

1. Genuine free status: no expiry, or self-hosted software with no licence fee.
2. Identity: a named current edition or distribution with an official source.
3. Core record: usable leads, contacts, deals, or structured records.
4. Ownership: a record can have a responsible person or controlled workflow.
5. Export: the buyer can test a useful data export before production use.
6. Limit clarity: user, record, proposal, storage, or other main limit is published or testable.
7. Access control: the team can restrict production access appropriately for its size.
8. Continuity: data can be backed up, migrated, or reconstructed under a written exit plan.

A product can pass these gates and still be a poor solar fit. The pass only means it deserves a pilot.

Fail or Hold Gates

We excluded or held an option when:

• the offer was only a time-limited trial
• the current official page contradicted itself on a main limit
• the team could not produce a usable export
• essential access ownership was unclear
• the required workflow depended on an unverified integration
• the plan forced production data into an uncontrolled personal account
• the team could not support hosting, security, updates, or recovery

Bitrix24 is held rather than ordered. Its current pricing table says the Free plan is for 1 to 2 users, while the FAQ on the same page says unlimited users.

That conflict does not prove either statement false. It means the user limit needs written confirmation or an account test before comparison.

Scoring Dimensions After the Gates

Passing options were compared on these dimensions:

We did not assign invented scores. The correct order changes with users, workflow, risk, and available administration.

At-a-Glance Comparison on 10 August 2026

“Best” therefore needs a sentence after it. Best for a solo India proposal workflow differs from best for 3 generic CRM users or a self-hosted technical team.

QuickEstimate Free: Solar-Specific Fit for 1 User

QuickEstimate is the only candidate here whose current free pricing page explicitly packages an India solar proposal workflow. That makes it relevant to a solo installer, not a universal first-place product.

The QuickEstimate pricing page lists ₹0 forever, 1 user, and 10 proposals per month. It also lists branded subsidy-ready PDFs, PM Surya Ghar calculation, WhatsApp send, iOS and Android apps, and email support.

Those are company-published claims. A pilot should test the output, calculation inputs, branding, WhatsApp path, mobile behavior, export, and support response.

Disclosure: SurgePV and QuickEstimate share ownership. This sponsored link creates a commercial conflict. Apply the same evidence, security, export, and exit gates to QuickEstimate and every alternative.

Where It Fits

The narrow fit is a solo India solar installer who sends no more than the published proposal limit. The user also needs the listed proposal and subsidy workflow.

The plan stops fitting when a second person needs production access. It can also stop fitting when proposal volume crosses the monthly limit.

Do not share one login across staff to avoid the user boundary. Shared credentials weaken ownership, offboarding, audit, and incident response.

What to Test

• lead creation and duplicate handling
• proposal assumptions and version control
• subsidy wording, eligibility inputs, and disclaimers
• quote items, tax fields, approvals, and customer acceptance
• WhatsApp consent, delivery record, replies, and opt-out handling
• mobile parity and low-connectivity behavior
• export of contacts, deals, notes, activities, and proposals
• deletion, account ownership, and upgrade behavior

The free page does not list every CRM, security, or export limit. Treat an unlisted field as unresolved, not unlimited.

Zoho CRM Free: Configurable General CRM for 3 Users

Zoho is a better fit when a 3-person team needs general CRM rather than a packaged solar quotation flow. It requires more process design.

The Zoho CRM pricing page lists the Free edition at ₹0 for 3 users. It lists contact management, reminders, workflow automation, email templates, activities, imports and exports, reports, APIs, and mobile apps.

The page also gives plan-level limits. Examples include 10 free custom email templates, export up to 10 times, and 5,000 API calls daily.

Those current limits should be checked inside the India account. A global help article, local pricing page, and in-account counter can differ by edition or rollout.

Where It Fits

Zoho Free can hold leads, accounts, contacts, deals, tasks, and basic reports for a small sales team. It is not solar-specific by default.

The team must define fields for connection type, location, sanctioned load, roof, system size, survey, equipment, quotation version, subsidy scenario, approval, installation, and service.

Solar proposal generation may require a separate document process. Do not claim a free solar quotation integration until the exact workflow and plan support are verified.

Upgrade Triggers

• fourth production user
• more exports than the current allowance
• higher API use
• multiple pipelines or deeper process control
• advanced roles, approval, audit, or security needs
• built-in calling or wider email integration
• inventory, CPQ, portal, or accounting requirements

The India solar CRM workflow guide helps define those requirements before configuration.

HubSpot Free CRM: 2 Users and 1 Deal Pipeline

HubSpot fits a 1-person or 2-person team that wants a well-documented generic contact and deal system. The free boundary is smaller than many old comparison pages report.

The HubSpot free CRM page states up to 2 users, 1,000 contacts, and no expiration date. Its Sales pricing table lists 1 deal pipeline in Free tools.

The same table lists limited email templates and snippets. It also identifies HubSpot branding on some customer-facing free tools.

Where It Fits

A very small team can track contacts, deals, activities, and a single sales pipeline. It can test whether staff will adopt CRM before paying for deeper sales functions.

One pipeline may be too narrow when residential, commercial, channel, and service processes need separate stage logic. Avoid combining unlike stages merely to remain free.

No packaged solar survey, design, subsidy, DISCOM, installation, or warranty workflow was verified on these pages. The team must configure records or connect separate tools.

Upgrade Triggers

• third user
• more than 1,000 contacts
• second pipeline
• more templates or snippets
• automation beyond the free boundary
• advanced permissions, reporting, forecasting, or integrations
• removal of customer-facing branding where required

Count all contacts, not only open opportunities. Old leads, customers, vendors, and service contacts can consume the same database boundary.

Odoo One App Free: CRM-Only Scope for Unlimited Users

Odoo uses a different free model. It allows one app rather than a small user count.

The Odoo pricing page lists One App Free at $0, one app, unlimited users, and Odoo Online. It states that required dependent apps are included.

This can fit a larger team that uses Odoo CRM as its single selected app. Installing other independent apps can trigger a paid plan.

Where It Fits

The buyer values many CRM users and can keep the operating boundary inside one app. A responsible administrator can configure the solar fields and process.

Implementation is not free. The pricing page separates implementation and expert services from the subscription.

The team should also check whether its required API, customization, multi-company, accounting, quotation, service, or external integration path changes the edition.

Pilot Questions

• Which installed apps are included as CRM dependencies?
• Which desired app would trigger payment?
• Can the team import and export every required object?
• Are roles and record ownership sufficient?
• How are custom fields and workflow changes governed?
• What backup and restore evidence can the buyer obtain?
• Who owns implementation and future upgrades?

Do not call One App Free an unlimited business suite. Its free boundary is one selected app plus defined dependencies.

Airtable Free: A No-Code Prototype, Not Packaged CRM

Airtable can model leads, contacts, projects, tasks, and related records. The solar team builds the schema, views, forms, automations, controls, and reports.

The Airtable plan documentation lists 1,000 records per base and 1,000 API calls per workspace monthly. It also lists 1 GB attachment storage per base and 2 weeks of history. Free workspaces permit 5 Editor or Creator collaborators.

The same documentation explains that a new account’s first workspace may start with a 14-day Team trial. A buyer must inspect the final Free state, not evaluate temporary Team functions as free.

Where It Fits

Airtable can support a lightweight prototype or controlled manual pipeline. It is useful when the team understands relational records and accepts configuration work.

The 1,000-record limit needs interpretation. A normalized design may store leads, sites, contacts, activities, proposals, and service events as separate records.

One customer journey can therefore consume several records. Estimate growth from the proposed schema, not customer count alone.

Risks and Triggers

• the record model reaches 1,000 records per base
• a sixth Editor or Creator needs access
• API usage reaches the monthly cap
• attachments approach the base limit
• 2 weeks of history is insufficient for recovery or audit
• required automation or administration sits outside Free
• a custom builder leaves without documentation

Use the CRM versus spreadsheet comparison before deciding whether a custom no-code build is justified.

SuiteCRM: No Licence Fee, Real Operating Cost

SuiteCRM represents the self-hosted open-source path. It removes per-user software licence fees, not infrastructure or responsibility.

The SuiteCRM pricing page says the software is free to download and carries no per-user licence fee. It also states that buyers pay for hosting, setup, and support according to the chosen model.

Where It Fits

A technical team wants control of its deployment and data. It has named owners for hosting, security, updates, backups, monitoring, email, integrations, and recovery.

The buyer can configure solar fields and modules. That flexibility transfers product-management work to the buyer.

Cost Boundary

Budget these items even when the licence line is ₹0:

• server or cloud hosting
• domain, certificate, email, and monitoring
• installation and hardening
• upgrades, patches, and dependency changes
• backups and tested restore
• identity, MFA, roles, and audit configuration
• development and integration work
• staging and change control
• support and incident response
• migration and administrator time

Self-hosting is not a good free option when nobody owns those tasks. The operational risk can exceed a paid cloud subscription.

Bitrix24: Hold Until the Free User Limit Is Clear

Bitrix24’s current official page contains useful detail and a material conflict. The top Free plan table says 1 to 2 users, 5 GB storage, basic deals and contacts, tasks, calendars, chat, and video.

The FAQ on the same Bitrix24 pricing page says the free account permits unlimited users. It also says telephony and some marketplace apps require paid plans.

These statements cannot both define the same current Free boundary without another distinction. We therefore do not order Bitrix24 among the passing options.

To resolve the hold:

1. Create a new account without activating the 15-day trial.
2. Record the edition and region.
3. Attempt the required user count.
4. Capture the subscription screen and limits.
5. Ask Bitrix24 to explain the page conflict in writing.
6. Retest export, CRM, storage, telephony, apps, and downgrade behavior.

This is what evidence-based comparison looks like. A vendor can be relevant while one unresolved limit blocks a recommendation.

Spreadsheet Baseline: ₹0 Does Not Make It a CRM

A spreadsheet can be a reasonable baseline for one careful operator with a low lead volume. It can record contact, source, owner, stage, next action, amount, and notes.

It becomes risky when several people edit, copy, download, or message from separate tools. Duplicate resolution, ownership, access, history, and offboarding become manual.

Compare the spreadsheet on the same gates:

• Can it stop duplicate leads?
• Can every lead have one accountable owner?
• Can stage changes require fields?
• Can reminders be generated reliably?
• Can consent and opt-out status follow the contact?
• Can proposal versions be tied to the correct opportunity?
• Can access be removed without leaving local copies?
• Can changes and deletions be audited?
• Can attachments and histories be exported together?
• Can the team restore a known-good version?

If the answer is no, the spreadsheet is not free. Staff time and failure risk are the cost.

Test the Complete Solar Workflow

A free CRM should be tested from enquiry to service, even when the first pilot covers only sales.

Use this lifecycle:

1. Capture the lead and original source identifier.
2. Record consent, preferred channel, and suppression status.
3. Detect duplicates across phone, email, and source lead ID.
4. Assign owner, territory, and response task.
5. Qualify site, consumer, connection, roof, load, and interest.
6. Schedule survey and collect controlled documents.
7. Create technical and price assumptions outside or inside the CRM.
8. Approve and version the quotation.
9. Deliver it through an approved channel and record evidence.
10. Track acceptance, payment, approval, installation, and handover.
11. Preserve equipment, warranty, service, and referral history.

Generic CRM options need field and stage configuration. QuickEstimate publishes more of the proposal workflow, but its entire lifecycle and limits still need testing.

Keep technical system design outside the CRM unless the selected edition proves that scope. A dedicated solar design software workspace should own module layout, stringing, energy, and financial assumptions, while the CRM owns the customer record and sales status.

Pair the chosen CRM with solar proposal software only when the handoff is controlled. The CRM with quotation guide explains system ownership and version rules.

Verify Communications and Integrations Separately

WhatsApp, email, and telephony are not one checkbox. Each channel has setup, consent, templates, identity, usage, logging, reply, opt-out, and cost questions.

For WhatsApp, verify:

• official account and number ownership
• lawful consent and approved templates
• outbound and inbound message support
• reply routing and staff ownership
• delivery status and error logs
• stop requests and suppression
• provider, conversation, template, and connector fees
• export and retention of conversation history

QuickEstimate’s free page lists WhatsApp send. It does not prove every two-way, automation, consent, or history requirement.

For email, test mailbox connection, sender authentication, branding, templates, daily limits, reply capture, bounce handling, suppression, and offboarding.

For telephony, test number ownership, recording law, consent, call logs, disposition, storage, and fees. Bitrix24’s current page places telephony outside its Free plan.

Integrations require the same discipline. “API available” does not prove the free plan supports the required objects, direction, quota, authentication, retries, webhooks, or audit.

The CRM with Tally guide shows why accounting ownership must be defined. Do not infer Tally support for any option in this comparison.

Security, Administration, Audit, and Backup

Small free plans often lack the administration expected by a growing team. That does not make them unsafe by definition. It makes the risk review specific.

Check:

• legal account owner and recovery contacts
• multi-factor authentication
• role and record permissions
• shared-login prohibition
• administrator count and emergency access
• session, device, and mobile controls
• audit history for edits, exports, and deletion
• encryption and processor terms
• data region and subprocessors
• retention and deletion settings
• vendor and support access
• incident notification process
• export and backup procedure
• tested recovery and offboarding

An export is not automatically a backup. A CSV may omit attachments, notes, messages, activities, users, permissions, relationships, and audit history.

Define the minimum recovery package. Test it before importing all production leads.

The mobile solar CRM guide adds lost-device, offline, session, permission, and sync checks.

Calculate Total Cost Beyond ₹0

Use a 3-year cash and staff-time model. Keep each input visible.

Total cost = subscription + implementation + migration + integration + channel usage + hosting + support + administration + training + change + exit

For a free cloud plan, subscription starts at ₹0. Every other term can still be positive.

Estimate administrator cost:

Annual admin cost = admin hours per month × 12 × approved loaded hourly cost

Estimate manual-work cost:

Annual manual cost = repeated minutes per transaction ÷ 60 × annual transaction count × loaded hourly cost

These formulas do not provide market rates. The buyer supplies wages, volume, tax, and vendor quotes.

Use the India CRM pricing guide to normalize paid upgrade scenarios. Compare current gross cash, tax treatment, and contract timing with professional advice.

Record Upgrade Triggers Before Launch

Each pilot should have measurable triggers:

• second, third, fourth, or sixth user, depending on plan
• contact, record, attachment, or storage threshold
• proposal volume
• additional pipeline
• automation or API quota
• required WhatsApp, email, telephony, accounting, or lead connector
• advanced permission, audit, SSO, or backup need
• support response or onboarding need
• local service or implementation capacity

Set a warning below the hard limit. Do not start procurement on the day production stops.

Plan the Exit Before Importing Data

Exit risk is the effort and loss involved when changing plans or systems. Free software can create high exit risk through custom fields, attachments, messages, and undocumented automations.

Before launch, obtain or test:

• full contact, account, lead, and deal export
• stable record IDs
• notes, tasks, activities, and stage history
• users and ownership
• files and proposal versions
• email, WhatsApp, and call references
• custom field definitions
• automation and integration inventory
• consent and suppression records
• deletion and account-closure process

Run a small migration rehearsal. Import the export into a clean table and reconstruct 5 complete customer histories.

If relationships cannot be rebuilt, document the gap and cost. Choose a different system when the exit risk is unacceptable.

A 30-Day Pilot Scorecard

Do not pilot every attractive feature. Pilot the operating controls that decide success.

Score pass, fail, or unresolved. Do not create a weighted number that hides a failed security or export gate.

Procurement Checklist

1. Define users, lead volume, sources, and sales processes.
2. Separate CRM, solar design, quotation, accounting, communications, and service ownership.
3. Verify the free edition and limits in a clean account.
4. Exclude trial-only functions from the production design.
5. Map fields, stages, required data, and ownership.
6. Review privacy, security, retention, consent, and vendor access.
7. Test imports, exports, attachments, IDs, and recovery.
8. Price implementation, migration, connectors, usage, support, and admin.
9. Write upgrade triggers and an approved budget path.
10. Run the 30-day pilot with real roles and controlled sample data.
11. Document the configuration, administrator, and integration inventory.
12. Approve production use only after all pass gates close.

The best solar CRM software comparison can support the paid shortlist after free-plan fit is exhausted. Recheck every plan because software packaging changes.

Conclusion

Free solar CRM software is a fit decision, not a universal ranking.

• QuickEstimate has the narrowest documented India solar fit for 1 user and 10 monthly proposals.
• Zoho CRM supports 3 free users for configurable general CRM.
• HubSpot supports up to 2 users and 1,000 contacts with 1 deal pipeline.
• Odoo offers one free app for unlimited users, with implementation and app-boundary tradeoffs.
• Airtable supports a limited no-code prototype.
• SuiteCRM removes licence fees but transfers operations to the buyer.
• Bitrix24 remains on hold until its conflicting current user limits are resolved.

Start with the pass gates, pilot the complete workflow, and export the data. Upgrade or exit before a free limit becomes a production incident.

Frequently Asked Questions

What is the best free solar CRM software in India?

There is no universal winner. QuickEstimate’s current Free plan fits 1 user needing its documented India solar proposal workflow. Zoho CRM fits up to 3 users needing configurable general CRM. Verify every limit in a clean account before choosing.

What does QuickEstimate Free include?

Its public pricing page dated 10 August 2026 lists ₹0 forever, 1 user, and 10 proposals monthly. It also lists branded subsidy-ready PDFs, PM Surya Ghar calculation, WhatsApp send, iOS and Android apps, and email support. These are vendor-published claims.

Is Zoho CRM Free a trial?

No. Zoho’s current pricing page lists a free-forever edition for 3 users. It includes general CRM functions, but a solar team must configure and test its own fields, stages, quotations, approval handoffs, and communications.

How many users does HubSpot free CRM allow?

HubSpot’s free CRM page states up to 2 users and 1,000 contacts with no expiration date as of 10 August 2026. Its Sales pricing table lists 1 deal pipeline and other free-tool limits.

Is open-source CRM really free?

Open-source software can have no per-user licence fee, but production operation still costs money. Budget hosting, setup, security, updates, backups, email delivery, integrations, support, administration, and recovery.

Can Airtable replace a solar CRM?

Airtable can support a lightweight custom lead table and pipeline, but it is a no-code database rather than packaged solar CRM. The free plan’s record, editor, API, attachment, and history limits can become early upgrade triggers.

Does a free CRM include WhatsApp, telephony, and email?

Do not assume so. A free plan may omit a channel, limit it, add branding, require a separate provider, or charge usage fees. Verify consent, templates, numbers, logs, ownership, opt-out, and export behavior.

When should a solar company upgrade from free CRM?

Upgrade when the required users, records, proposals, storage, pipelines, automation, integrations, permissions, audit, support, or exports exceed verified limits. Price the migration and exit options before the trigger occurs.

Is SurgePV a free solar CRM?

No. SurgePV has no verified native CRM and is not ranked as one. It provides solar design, shadow analysis, generation and financial modeling, and proposal tools that can sit beside a separately selected CRM.
