Best Free Software for Sole Traders 2026: 8 Tools Tested

Discover the ideal and completely free stack for sole traders in 2026. Invoicing, CRM, accounting... My comparison of the 8 best tools to get started.

TL;DR

For a sole trader in 2026, building a solid foundation without any costs is entirely possible. The ideal free stack combines compliant French invoicing software like Henrri or Tiime with a powerful CRM like HubSpot to manage your contacts. For prospecting, Apollo.io has become essential for finding prospects and contacting them. This guide breaks down 8 reliable free tools to launch and manage your business without spending a dime upfront.

Why Dedicated Software Is Essential, Even for Sole Traders?

When you're starting out, the temptation to use Excel and your email is strong. I went through that at the very beginning of SaaS Radar. You think you're saving time and money. It's a mistake that costs you dearly later. Managing your invoicing on a spreadsheet opens the door to oversights, calculation errors, and worse—legal non-compliance. The 2018 anti-fraud VAT law imposes strict rules: immutability, data security, retention, and archiving. An Excel file is anything but immutable.

Beyond invoicing, tracking your prospects on a sticky note or in the back of your mind is the best way to lose them. A sole trader is a business owner. You must have a clear view of your sales pipeline, your follow-ups, and your opportunities. Forgetting a follow-up means potentially losing a deal. Using specialized free tools isn't a luxury—it's a necessity to professionalize your activity from day one. It's the foundation that lets you focus on your core business, not admin work. The good news? The market is packed with robust freemium solutions designed for us.

Henrri

For who: The sole trader looking for 100% free, simple, effective, and French invoicing software without frills.

Strengths: Henrri built its reputation on a simple model: invoicing is free. And they deliver on that promise. The interface is clear, creating quotes and invoices is quick. The tool complies with French legislation, which is the most critical point. You can customize your documents, track payments, and even manage a small catalog of products or services. No limits on the number of clients or invoices, which is rare.

Limitations: The business model relies on selling add-on modules (accounting, automated reminders...). The free version is strictly limited to basic invoicing. No advanced inventory management or bank synchronization without paying. The interface, while functional, is starting to look dated compared to more modern competitors.

Indicative pricing (after free): Core invoicing remains free. Add-on modules are à la carte, starting at €7.50 ex-tax/month.

Tiime

For who: The freelancer anticipating working with an accountant or wanting slightly more than basic invoicing, especially on pre-accounting.

Strengths: Tiime goes further than Henrri. Beyond free and unlimited invoicing, the mobile app is excellent for scanning receipts. Tiime's real strength is its ecosystem. If your accountant uses Tiime, document transmission is automated. That's a massive time saver. The interface is more modern and pleasant than Henrri's.

Limitations: Free access requires inviting your accountant to the platform. If they're not there or you don't have one, the tool remains usable but loses much of its appeal. Some features, like bank synchronization, are paid if you don't have a partner accountant.

Indicative pricing (after free): Free with a partner accountant. Paid plans for extra features (like bank sync without an accountant) start around €15 ex-tax/month.

Indy

For who: The sole trader who wants a true all-in-one to manage accounting, URSSAF declarations, and invoicing in one place.

Strengths: Indy changed the game with a very comprehensive free offer. It includes bank synchronization, automatic transaction categorization, quote and invoice creation, and most importantly, business management with clear dashboards. The big plus: help with declaring your revenue to URSSAF. It's like having a personal accounting assistant. My experience with freelancers in my network is unanimous: it's a tool that removes considerable mental burden. For deeper analysis, check out our comparison Indy vs Freebe: Which Software for Freelancers in 2026?.

Limitations: The free plan is limited to 10 quotes and invoices per year. That's the main catch. It's enough for someone with few clients and big contracts, but quickly limiting for a freelancer with many small projects. The tool is heavily oriented toward "accounting" and may seem less direct for simple invoicing than Henrri.

Indicative pricing (after free): Paid subscriptions to unlock limits and add VAT management or business creation start at €22 ex-tax/month.

How to Choose Your Free Invoicing Software?

Faced with these options, the choice depends on your situation. If your only need is to issue compliant invoices without overthinking, Henrri is unbeatable. If you plan to hire an accountant or have lots of receipts, Tiime is better suited. If your priority is automating your accounting and declarations, Indy is the best choice, provided the invoice limit isn't a problem. Don't forget to think ahead. A tool that can grow with you is an asset. For broader guidance, I recommend reading our article on the best invoicing software for freelancers in 2026.

Beyond Invoicing: CRM, Your Growth Best Friend

Once invoicing is under control, growth becomes the issue. And growth comes through managing clients and prospects. A CRM (Customer Relationship Management) isn't just for big companies. For a sole trader, it's the central nervous system of your business. It lets you know who you've contacted, when, what was said, and when to follow up. Forgetting a follow-up means potentially losing a deal. The free CRM market is incredibly rich, and not taking advantage of it is a strategic mistake. If you want to dig deeper, our guide on the best free CRM in French in 2026 is a great starting point.

HubSpot CRM

For who: The ambitious sole trader who wants an extremely powerful tool to structure long-term growth.

Strengths: HubSpot's free CRM is the market standard, and for good reason. It manages up to 1 million contacts, tracks all interactions (emails, calls, meetings), creates visual sales pipelines, and provides side tools like a landing page builder, chatbot, or email marketing (with limits). Gmail and Outlook integration is seamless. It's a solid foundation for building your entire marketing and sales strategy.

Limitations: HubSpot is a powerhouse. Power means complexity. The learning curve can be intimidating for beginners. The free plan is generous on basics, but HubSpot's logo appears everywhere (emails, chatbot...). As soon as you want automation or advanced reports, pricing for add-on packages (Marketing Hub, Sales Hub) climbs fast.

Indicative pricing (after free): "Starter Hubs" start around €20/month, but the bill can quickly reach hundreds of euros for Pro versions.

Brevo (formerly Sendinblue)

For who: The freelancer looking for a simple, all-in-one marketing and sales platform of French origin.

Strengths: Brevo is the ultimate multi-tool. Its free plan offers not only functional CRM but also email marketing (up to 300 emails/day), website chat, and even SMS or WhatsApp campaigns (credits to purchase). The interface is unified and much simpler than HubSpot's. It's an excellent solution to centralize customer communication. It's a major player in email marketing, as we analyze in our guide on free email marketing.

Limitations: Brevo's CRM is less deep and customizable than HubSpot's. It's more oriented toward "contact management for marketing campaigns" than "managing complex sales pipelines." The 300 email/day limit can be reached quickly if you launch newsletters.

Indicative pricing (after free): Paid plans start at €19/month to increase sending quotas and remove Brevo branding.

Folk

For who: The sole trader who works heavily with their network and hates traditional CRMs. Ideal for consultants, agents, or freelancers in relationship-driven fields.

Strengths: Folk takes the opposite approach to bloated CRMs. It's contact-centric and collaborative. The interface looks like Airtable on steroids—highly visual and customizable. The Chrome extension to import LinkedIn contacts with one click is brilliant. You can create pipelines, but also simply lists of contacts you want to wish happy birthday or met at an event. It's a CRM that adapts to how you think.

Limitations: The free plan is limited to 100 contacts and 100 enrichments per month. That's very little. It's enough to start and test, but you'll hit the ceiling fast. The tool lacks "marketing" features (no native mass email like Brevo or HubSpot).

Indicative pricing (after free): Paid plans start at $19/user/month to lift contact limits.

How to Find Your First Clients Without Spending a Euro?

A good CRM is great. Filling it is better. Prospecting is the lifeblood. Fortunately, free tools also let you start the machine. It's about combining a data source (where to find prospects?) and a contact channel (how to reach them?). LinkedIn and email remain the two gold-standard B2B channels. Tools let you systematize part of this process, even with zero budget.

Apollo.io

For who: Absolutely every sole trader doing B2B prospecting. It's the game-changer of recent years.

Strengths: Apollo is a database of millions of B2B contacts paired with an email sequence tool. The free plan is incredibly generous: 120 email credits/year (that's 10/month) to find your prospects' work email addresses and 60 mobile credits/year. You can filter the database with ruthless precision (industry, company size, job title, technologies used...). The Chrome extension finds contact info directly from their LinkedIn profile. This single tool can bring you your first clients.

Limitations: There's a real learning curve. You need to understand the logic of filters, lists, and sequences. The 10 email credits per month are enough for highly targeted prospecting, but not for volume campaigns. Data quality, while very good, isn't 100% perfect.

Indicative pricing (after free): Paid plans offering far more credits start at $49/user/month.

Walaaxy

For who: The freelancer who wants to automate LinkedIn prospecting simply and safely.

Strengths: Walaaxy connects to your LinkedIn account and lets you create automated sequences: profile visits, connection requests with personalized messages, follow-up messages... The free plan allows up to 80 invitations per month. It's a great way to reach a targeted audience without spending days on it. The interface is playful and very easy to learn. Walaaxy simulates human behavior to stay under LinkedIn's radar. For more, check out our prospecting email examples that work for your outreach messages.

Limitations: The free plan doesn't allow complex sequences (for example, combining LinkedIn and email). It's also volume-limited. The tool is entirely dependent on LinkedIn; if your account is restricted, Walaaxy is unusable. You must use it intelligently, without spamming.

Indicative pricing (after free): Paid plans for multi-channel and more volume start at €56/month.

Comparison Table of the Free Stack for Sole Traders

My Final Recommendation for 2026

There's no single perfect stack, but combinations suited to different profiles.

• For the Efficient Minimalist: You want to get straight to the point. Your stack: Henrri for invoicing + Folk to manage your few key clients and prospects. It's simple, quick to set up, and covers 80% of basic needs without any complexity.

• For the Empire Builder: You're thinking bigger. Your stack: Tiime to prepare the ground with an accountant + HubSpot CRM to build a robust sales machine + Apollo.io to feed that machine qualified prospects. This is a stack that can follow you from 0 to multiple employees.

• For the All-in-One Lover: You hate juggling between tabs. Your stack: Indy if accounting is your priority and invoices are few, or Brevo if marketing and communication matter most. These tools try to do everything in one place with trade-offs, but great ease of use.

The most important thing is to start. Choose a stack, even if imperfect, and launch. You'll adjust it along the way. The worst decision is deciding nothing and staying on Excel.
