TLDR (Summary)
Plutio ($19/month) is the strongest pick for a one-person business because the CRM connects contacts directly to proposals, contracts, projects, time tracking, and invoices, so a single login replaces the 3-4 separate subscriptions most solo operators stack together. HoneyBook covers client intake and booking but has no project management or time tracking. HubSpot offers a free CRM but limits contacts to 1,000 and has no invoicing on any plan.
Below, 8 CRM tools compared on solo-business fit, what connects to billing and project delivery, and total cost of ownership when a team of one needs more than a contact database.
What a one-person business actually needs from a CRM
Most CRM feature lists are built for sales departments with dedicated reps, marketing coordinators, and operations managers. A one-person business fills all those roles at once, so the CRM needs to cover the full cycle from lead to paid invoice without requiring three other tools to finish the job.
Contact-to-billing connection
A solo business owner doesn't just track contacts. Every contact eventually becomes a proposal, a project, or an invoice. A CRM that stops at the contact record leaves the owner copying client details into a separate proposal tool, then again into an invoicing app, then again into a project tracker. Each copy-paste step costs time, and across 15-20 active clients, those minutes add up to hours every month. The CRM should carry client data from first inquiry to final payment without leaving the platform.
Flat-rate pricing over per-seat billing
Per-seat pricing makes sense for a 20-person sales floor. For a team of one, paying $14/user/month for a contact database that doesn't include invoicing or proposals means the CRM is the first line item in a stack of subscriptions. Add a billing tool ($10-20/month), a proposal tool ($10-15/month), and a project tracker ($10-15/month), and the total cost reaches $50-65/month before any of those tools talk to each other. Flat-rate pricing at $19/month for a platform that bundles CRM with billing, proposals, and project management changes the math entirely.
Project management that follows the client record
Once a lead becomes a client, the work starts. A CRM without project management forces the owner into a separate app for task boards, deliverable tracking, and deadlines. The client record in the CRM doesn't know the project exists, and the project tracker doesn't know the invoice is overdue. For a one-person business, the CRM isn't just a contact database. The CRM is the operating system where every client interaction, from first email to final invoice, stays visible on one screen.
Features solo businesses can skip
Lead scoring assigns points to prospects based on engagement signals, useful when a team of 10 reps prioritizes 500 inbound leads per week, unnecessary when the owner knows every prospect by name. Marketing automation sequences, multi-stage pipeline hierarchies with 15 deal stages, and territory assignment rules all add complexity without value for a business where one person handles everything. The right CRM for a solo operator includes what gets used daily and skips what gets configured once and forgotten.
All-in-one platforms with CRM for solo businesses
All-in-one platforms bundle CRM with invoicing, proposals, project management, and contracts, so the contact record connects to every stage of the client relationship without requiring separate subscriptions. The starting price is higher than a standalone CRM because billing, contracts, and project tools come included alongside the contact database, but the total cost of ownership is usually lower than stacking 3-4 separate apps.
Plutio ($19/month)
Best for: solo business owners who need CRM tied to proposals, projects, invoices, and contracts in one workspace | Capterra: 4.6/5 | G2: 4.6/5
Plutio's CRM attaches every contact to the full lifecycle of the relationship: proposals, contracts, projects, time tracking, and invoices. Custom fields, tags, and filters organize contacts by project type, revenue, or relationship stage. Deal pipelines track leads from first inquiry through signed contract, and once a deal closes, the project inherits the client data, scope, and billing terms, so nothing gets re-entered. A white-labeled client portal at the owner's domain lets clients check project progress, view files, and pay invoices without sending emails for updates. Flat pricing at $19/month means adding 10 or 100 contacts doesn't change the bill.
- CRM connects to proposals, projects, contracts, invoices, and time tracking without switching tools
- White-labeled client portal where clients check progress and pay invoices at the owner's domain
- Flat-rate pricing ($19/month Core, $49/month Pro) with no per-seat or per-contact fees
- Deal pipeline tracks leads from inquiry through signed contract to active project
- No free plan, 14-day trial gives full access to test the CRM and every connected feature
- Advanced reporting and workflow automation available on Pro ($49/month) and Max ($199/month)
HoneyBook ($16/month, annual billing)
Best for: service-based solo businesses focused on client intake and booking | Capterra: 4.7/5 | G2: 4.5/5
HoneyBook's CRM focuses on the intake side of client management. Smart Files combine proposals, contracts, and payment requests into a single client-facing document, so prospects sign and pay from one page. Contact records track inquiry source, booking status, and payment history. But project management, time tracking, and task boards are absent from every plan, which the Plutio vs HoneyBook comparison covers alongside a recent price increase of up to 89% across all tiers. Automation requires the Essentials plan at $32/month (annual), and the client portal is limited to document signing and payment rather than ongoing project visibility.
- Smart Files combine proposals, contracts, and invoices in one client-facing view
- Contact records track inquiry source, booking status, and payment history
- Scheduling tools included on Essentials plan ($32/month)
- No project management or time tracking on any plan
- Automation requires Essentials plan ($32/month), not included on Starter
- Recent price increase of up to 89% across plans
Bonsai ($9/month, annual billing)
Best for: solo businesses that need contracts and invoicing bundled with basic contact management | Capterra: 4.6/5 | G2: 4.3/5
Bonsai bundles a contact list with attorney-reviewed contract templates, proposal tools, and invoicing at $9/month (annual billing), the lowest entry price on this list for an all-in-one platform. The CRM layer is basic compared to dedicated pipeline tools: no drag-and-drop pipeline view, no deal stages, and limited filtering options. Contact records store project and payment history but lack custom fields and tags for advanced segmentation. For solo businesses that need contracts and invoicing first and CRM second, Bonsai covers the basics, though the Plutio vs Bonsai comparison shows where the missing pipeline view creates friction as the client base grows past 10-15 active relationships.
- Attorney-reviewed contract templates ready to customize and send
- Contracts, proposals, and invoicing bundled at $9/month (annual)
- Contact records with project and payment history attached
- No pipeline view or deal stages for tracking leads
- Limited contact filtering and no custom fields for segmentation
- Payment processing delays reported by multiple Capterra reviewers
Moxie ($12/month)
Best for: solo businesses that want a visual pipeline view and invoicing at a flat rate | Trustpilot: 4.8/5 (520 reviews)
Moxie (formerly Hectic) includes a CRM with a visual pipeline view on the Starter plan at $12/month. Contacts flow through customizable deal stages, and invoicing and proposals are included at every tier. The client portal requires the Pro plan at $25/month, and the Teams plan at $40/month caps at 5 members. Most user reviews live on Trustpilot and AppSumo rather than G2 or Capterra, a verification gap the Plutio vs Moxie comparison explores alongside pricing and feature differences.
- CRM with visual pipeline view included at $12/month
- Invoicing and proposals included at every pricing tier
- Flat-rate pricing with no per-seat charges
- Client portal requires Pro plan ($25/month), not included on Starter
- Teams plan caps at 5 members
- Limited G2 and Capterra presence for review verification
All four platforms include invoicing alongside the CRM, but only Plutio connects a client from first inquiry through proposal, signed contract, active project, tracked time, and paid invoice in one workspace with a branded client portal included. HoneyBook handles client intake but drops off at project management. Bonsai bundles contracts at $9/month but has no pipeline view. Moxie includes the pipeline at $12/month but locks the client portal behind a $25/month upgrade.
Dedicated CRM tools for solo businesses
Dedicated CRM tools offer deeper pipeline management, contact tracking, and automation sequences, but none of them include invoicing, proposals, or project management. A solo business owner using any of these tools still needs 2-3 separate subscriptions to handle the work that follows a closed deal.
HubSpot CRM (Free / $20/user/month)
Best for: solo businesses that want free contact and deal tracking with room to grow | Capterra: 4.5/5 | G2: 4.4/5
HubSpot's free CRM includes contact management, one deal pipeline, and basic task tracking for up to 2 users. The free tier dropped from 1 million to 1,000 contacts in 2024, and 10 custom properties limit how much solo owners can customize contact records. HubSpot branding appears on every form, email, and landing page until the Starter plan at $20/user/month removes it. No invoicing, no proposals, no contracts, and no time tracking on any plan, so billing and project delivery need their own subscriptions. For a one-person business, HubSpot covers the contact database but not the work that happens after the lead converts.
- Free plan includes 1 pipeline, 1,000 contacts, and basic task management
- Contact timeline shows every email, call, and meeting in one view
- Starter plan ($20/user/month) removes branding and adds automation
- Free tier limited to 1,000 contacts and 10 custom properties
- No invoicing, proposals, contracts, or time tracking on any plan
- HubSpot branding on all forms and emails on the free plan
Pipedrive ($14/user/month, annual billing)
Best for: solo businesses that want visual deal pipeline management with drag-and-drop stages | Capterra: 4.5/5 | G2: 4.3/5
Pipedrive's entire interface centers on a visual deal pipeline where contacts move through customizable stages via drag-and-drop. The Essential plan at $14/user/month includes contact management, deal tracking, and email integration. But add-ons stack fast: LeadBooster costs $32.50/month, Campaigns adds $16/month, and Smart Docs for proposals requires the Professional plan at $49/user/month. No free tier exists, and billing, contracts, and time tracking are absent on every plan. A solo business owner using Pipedrive still needs an invoicing tool ($10-20/month), a contract tool ($10-15/month), and a project tracker ($10-15/month), pushing the real monthly cost past $50.
- Visual drag-and-drop pipeline with customizable deal stages
- Email integration tracks conversations directly on contact records
- Essential plan ($14/user/month) includes contact management and deal tracking
- No free plan available
- No invoicing, contracts, or time tracking on any plan
- Add-ons (LeadBooster $32.50/month, Campaigns $16/month) increase total cost quickly
Streak (~$50/user/month)
Best for: solo businesses that live in Gmail and want pipeline management inside the inbox | Capterra: 4.5/5 | G2: 4.5/5
Streak runs inside Gmail as a browser extension, turning the inbox into a CRM with pipeline views, contact records, and mail merge. Every email thread links to a deal record, so pipeline updates happen without leaving Gmail. But Streak removed its free plan, and the Pro plan at roughly $50/user/month makes it the most expensive per-user option on this list. Invoicing, proposals, and contracts are absent across all plans, and Gmail-only access means solo owners on Outlook or other email clients cannot use the tool at all. At $50/month for a contact database with no billing, no proposals, and no project management, Streak costs more than most all-in-one platforms while covering a fraction of the workflow.
- Runs inside Gmail with no separate app to manage
- Pipeline views, mail merge, and email tracking built into the inbox
- Every email thread links automatically to the associated deal record
- No free plan (removed in recent update)
- ~$50/user/month, most expensive per-user option on this list
- No invoicing, proposals, contracts, or project management on any plan
Zoho CRM (Free / $14/user/month)
Best for: solo businesses that want a free CRM with optional expansion into the Zoho ecosystem | Capterra: 4.3/5 | G2: 4.1/5
Zoho's free CRM includes basic contact and deal management for up to 3 users. The Standard plan at $14/user/month adds workflow automation, scoring rules, and custom dashboards. Zoho sits inside a broader ecosystem where Books handles accounting, Invoice handles billing, and Projects handles task management, but each app requires a separate subscription and its own configuration. The interface reflects enterprise design patterns with nested menus and settings screens that take weeks to configure properly. For a one-person business that wants a working CRM on day one, the setup time alone can consume more hours than the tool saves in its first month.
- Free plan includes 3 users with basic contact and deal management
- Standard plan ($14/user/month) adds workflow automation and scoring
- Part of the Zoho ecosystem with 40+ connected apps available
- Each Zoho app (Books, Invoice, Projects) requires a separate subscription
- Enterprise-oriented interface with weeks of configuration for basic setup
- Lowest review scores on this list (Capterra 4.3/5, G2 4.1/5)
Dedicated CRM tools cover pipeline management and contact tracking, but none include invoicing, proposals, or contracts. A solo business owner using HubSpot's free CRM still needs a billing tool ($10-20/month), a proposal tool ($10-15/month), and a project tracker ($10-15/month), which pushes total monthly spend past $45 before the CRM itself charges a dollar.
Feature comparison at a glance
All 8 CRM tools compared on solo pricing, invoicing, proposals, project management, and client portal access, the five dimensions that determine whether a CRM covers the full solo-business workflow or leaves gaps that need separate subscriptions.
| Tool | Price (solo) | Invoicing | Proposals | Project mgmt | Client portal |
|---|---|---|---|---|---|
| Plutio | $19/mo flat | Included | Included | Full (boards, Gantt) | Included |
| HoneyBook | $16/mo (annual) | Included | Smart Files | No | Limited (docs only) |
| Bonsai | $9/mo (annual) | Included | Included | Basic | No |
| Moxie | $12/mo | Included | Included | Included | Pro ($25/mo) |
| HubSpot | Free / $20/user/mo | No | No | No | No |
| Pipedrive | $14/user/mo | No | $49/user/mo plan | No | No |
| Streak | ~$50/user/mo | No | No | No | No |
| Zoho CRM | Free / $14/user/mo | Separate app | Separate app | Separate app | No |
Plutio is the only CRM on this list where contacts, deal pipelines, proposals, contracts, project management, time tracking, and invoicing all live in one workspace at a flat $19/month. Every other tool either skips invoicing entirely (HubSpot, Pipedrive, Streak), charges per user on top of missing features (Pipedrive, Streak, Zoho), or locks key capabilities behind higher tiers (HoneyBook, Moxie).
Picking the right CRM for a one-person business
The right CRM depends less on the contact database itself and more on what needs to happen after a lead says yes. A standalone CRM covers tracking and pipeline management but leaves invoicing, proposals, and project delivery to other tools, which multiplies the total cost and the data transfer between apps.
If billing and projects need to live alongside the CRM
Plutio bundles CRM with invoicing, proposals, contracts, project management, and a branded client portal at $19/month flat. Moxie includes CRM and invoicing at $12/month but locks the client portal behind the $25/month Pro tier. Both charge flat rates, so growing the contact list or adding a contractor doesn't change the bill. The Plutio vs Moxie comparison covers the feature gap between the two in more detail.
If client intake and booking drive the business
HoneyBook focuses on converting inquiries into signed contracts and collected payments through Smart Files. Contact records tie to the booking flow, so every proposal, contract, and payment stays linked. But once the contract is signed, there are no project boards, no time tracking, and no task management to handle the delivery side. Solo businesses that deliver ongoing work, rather than one-time bookings, hit the wall where HoneyBook's workflow ends and project management needs to start.
If budget is the primary constraint
HubSpot's free CRM works for basic contact tracking and one pipeline at no cost, but 1,000 contacts and 10 custom properties create a ceiling quickly. Zoho's free tier gives 3 users with basic deal management. Bonsai starts at $9/month (annual) with contacts, contracts, and invoicing included. The freelance invoicing guide compares billing tools that pair with free CRMs for solo owners who want to keep costs minimal during the early stages.
If Gmail is the primary workspace
Streak turns Gmail into a CRM without a separate app, so pipeline updates happen inside the inbox. But at roughly $50/user/month with no free plan, no invoicing, and no proposal tools, Streak costs more than most all-in-one platforms while covering only the contact tracking portion of the workflow. Solo business owners who want Gmail integration without the price tag can connect Plutio or HubSpot through native email syncing instead.
If the business is growing past one person
Per-seat CRMs multiply cost the moment a contractor, virtual assistant, or part-time team member needs access. Pipedrive at $14/user/month becomes $28/month for two users, $42/month for three, all without invoicing or project management included. Flat-rate tools keep the price fixed regardless of who needs access, which matters the moment the business adds its first hire. The scaling guide covers how to evaluate tools that grow alongside the business instead of charging more at each step.
Solo business owners who need the CRM to handle more than contact storage, who want leads becoming proposals, proposals converting to projects, and completed work becoming paid invoices, get the most value from all-in-one platforms where the contact record feeds into every stage of the business.
Common CRM mistakes solo business owners make
The most common CRM mistake for a one-person business is picking a tool designed for a 20-person sales team and trying to make it work for solo client management. Sales CRMs optimize for lead volume and pipeline velocity, not for tracking 15-25 ongoing client relationships across projects, invoices, and contracts.
Choosing a CRM that stops at the contact database
A CRM that stores contacts but doesn't connect to invoicing or project management creates a data island. Client details sit in the CRM while proposals go through one tool, invoices through another, and project updates through a third. Every manual copy-paste of a client's billing address from the CRM into an invoice template represents work the CRM should have handled, and the spreadsheet CRM article tracks how those manual steps compound into hours of lost time each month.
Paying per seat when working alone
Per-seat pricing makes sense for a company with 50 sales reps. For a solo business owner, $14/user/month for Pipedrive or $50/user/month for Streak buys a contact database without invoicing, proposals, or project management. A flat-rate tool like Plutio at $19/month includes CRM alongside every other workflow tool, which often costs less than stacking a per-seat CRM with separate billing, proposal, and project apps.
Overbuilding before the first lead enters the pipeline
Zoho CRM and HubSpot offer extensive pipeline customization: lead scoring rules, multi-stage automation sequences, territory assignments, and custom reporting dashboards. Spending weeks configuring 12-stage pipelines and automation workflows before a single lead enters the pipeline means investing setup time that doesn't generate revenue. Most one-person businesses need 3-5 deal stages: inquiry, proposal sent, contract signed, project active, and complete. Starting with those stages and adding complexity based on real patterns prevents building a CRM that collects dust.
Ignoring what happens after the deal closes
Dedicated CRMs track leads through the pipeline, but once the contract is signed, the CRM's job is done. The project still needs task management, time tracking, deliverable handoff, and billing. A CRM that connects to the full workflow, where a closed deal automatically creates a project with the client's details, scope, and billing terms already attached, removes the gap between winning the work and starting the work, which is exactly where solo business owners lose the most time.
