The best small business CRM is the one your team will actually keep updated, at a price that still makes sense when you grow. For a team of one to three people, a free plan from Zoho or HubSpot is a sensible start. For a team that wants CRM, quotes, invoicing and email in one place, and wants to pay only for what it uses, we think OK Technology is the strongest fit. Below we compare six options on cost model, limits and who each suits.
TL;DR
- There is no single best CRM. Choose by team size, by how many other tools you want to replace, and by how you prefer to pay.
- Free plans exist, but they come with hard caps. Zoho CRM's free edition stops at 3 users, and the whole team must upgrade when you need a fourth.
- Per-user plans suit sales-led teams with a steady headcount. Pay-per-action suits teams whose volume of leads, emails and invoices changes month to month.
- OK Technology has no plan tiers. You pay per action, for example 0.02 EUR per email and 0.03 EUR per invoice created, and the CRM sits next to billing, quotes and email.
- Test any CRM with your real data for a week before you commit.

What a small business actually needs from a CRM
A CRM for a small business does one job well: it keeps every contact, conversation and deal in one place so nothing depends on someone's memory or inbox. You do not need millions of records for that. One CRM strategy paper makes the point that the value for small firms lies in moving from firefighting to proactive relationship management, not in data volume.
Before you compare products, write down five things:
- Who will use it. Two founders and a part-time bookkeeper behave differently from a ten-person sales team.
- What happens after a deal is won. If you then need a quote, a contract and an invoice, check whether the CRM does that or hands you to another tool.
- Where your email lives. Sending from inside the CRM saves copy and paste. Sending from Gmail or Outlook needs an integration.
- How you want to pay. Per user per month, a flat plan, or per action.
- How hard it is to leave. Ask whether you can export contacts and deals as files.
The fifth point matters more than most buyers think. Cheap software gets expensive when you cannot take your data with you.
The options at a glance
This table compares how each option charges and where it fits. We only give a price where a source we checked states it. For everything else, check the vendor's current UK page, because plans and currencies change.
| Option | How you pay | Best for | Watch out for |
|---|---|---|---|
| OK Technology | Pay per action, no plan tiers | Teams that want CRM, billing and email in one place | Costs follow usage, so heavy senders should model volumes |
| Zoho CRM | Free for up to 3 users, then per user | Very small teams, or firms already using other Zoho apps | Free edition lacks custom modules and advanced reporting |
| HubSpot CRM | Free CRM, paid upgrades | Teams that want marketing and sales together | Costs rise as you add paid features |
| Pipedrive | Per user per month | Sales-led teams that live in a pipeline | Narrower than an all-in-one platform |
| Capsule | Per user per month | Simple contact and deal tracking | Fewer built-in finance tools |
| Freshsales | Per user per month | Teams wanting a fast-to-set-up sales CRM | Another tool is needed for invoicing |
OK Technology: CRM, billing and email on pay-per-action
OK Technology is a single platform that combines CRM, project management, sales, marketing automation, finance and billing, document storage, email, calendar and video calling. The idea is to stop the tool sprawl that comes from a CRM in one app, invoices in another and documents in a third. We claim it saves over 9 hours a week for teams that consolidate.
The pricing model is the unusual part. There are no plan tiers. Your wallet is debited when you do something. The published rates on the pricing page include:
- CRM leads: 0.02 to 0.87 EUR per lead, one-off
- Email: 0.02 EUR per email
- Campaign sends: 1 EUR per 1,000 sends
- Quote created: 0.02 EUR
- Contract created: 0.04 EUR
- Invoice created: 0.03 EUR, and sending an invoice is 0.02 EUR plus 0.05 EUR per MB
- Documents: 0.25 EUR each
- Storage: 0.2 EUR per GB per month
- Video call: 0.1 EUR per call plus 0.02 EUR per minute
A worked month
Take a small agency in a quiet month. It sends 300 emails (6 EUR), creates 40 quotes (0.80 EUR), creates 20 invoices (0.60 EUR), sends those 20 invoices (0.40 EUR, plus 0.05 EUR per MB of attachments), stores 5 documents (1.25 EUR) and keeps 10 GB of files (2 EUR). That comes to 11.05 EUR before attachment size. A busy month costs more, a quiet one costs less, and nobody pays for a seat that sat unused.
That is the trade-off to understand. A per-user plan gives you a predictable bill. Pay-per-action gives you a bill that follows your activity. If your volume is steady and high, work out the numbers first. If it is lumpy, or you have outgrown your current tools, it can be much cheaper.
Where it fits best
We built it for small business owners, project managers, finance teams, marketers and hospitality operators who want one system instead of five. Two practical reads if you are weighing it up: our guide to CRM with billing for SMBs and our breakdown of pay-per-action CRM email sends.
If you need help setting it up, business consulting is 100 EUR per hour and technical help is 50 EUR per hour. There is also a dedicated subdomain at 29 EUR per month and a custom domain with hosting at 1 EUR per month for those who want a white-label setup.
Zoho CRM: the strongest free start for tiny teams
Zoho CRM has a permanent free edition, not a time-limited trial. According to a Zoho partner's breakdown of the free plan, it supports up to 3 users, needs no credit card and covers leads, contacts, accounts and deals. It lacks custom modules, advanced reporting and most AI features. When you need a fourth user, the whole team moves to a paid edition, which the same source puts at about $14 per user per month billed annually.
That makes it a good fit for a one to three person business that wants structured lead and deal tracking, especially if you will adopt other Zoho apps later. If you plan to hire quickly, expect an upgrade sooner than you think. For a practical example of keeping things lean, see this walkthrough on building a simple CRM for a small contractor, which is useful when you are deciding how much CRM you need at the start.
HubSpot CRM: marketing and sales in one place
HubSpot is a common first pick because its CRM has a free tier and sits alongside marketing tools. One comparison of free options describes it as a free-forever plan with more than basic contact management. A source on CRM choice for small firms says HubSpot suits teams that want marketing and sales in one place.
The catch is the usual one with free tiers: the paid features you eventually want, such as automation and deeper reporting, come at higher tiers. Check the current UK pricing page for the features you need, not just the free headline.
Pipedrive: for teams that live in the pipeline
Pipedrive is a sales-first CRM. Its visual pipeline is the main attraction, and it works well when your business is a sequence of deals moving through stages. UK reviewers regularly list it next to HubSpot, Zoho, Salesforce Essentials and Freshsales in their small business round-ups. It is priced per user, so a larger sales team means a larger bill. It is narrower than an all-in-one platform, so invoicing and document work usually happen elsewhere.
Capsule: simple contact and deal tracking
Capsule is a UK-founded CRM that UK buyers often shortlist for simple relationship tracking. It suits businesses that find larger systems heavy. As with Pipedrive, the strength is simplicity, and the limit is that finance and project work live in other tools.
Freshsales: a quick-to-set-up sales CRM
Freshsales comes from Freshworks. A Zoho versus Freshsales comparison describes it as a cleaner, faster-to-set-up sales CRM, while Zoho is known for the widest tier ladder in the category. Choose it if you want to be productive in an afternoon and do not need a sprawling feature set.
How to compare them fairly
Feature lists look alike. These criteria separate the options.
Real cost at your size
Count the cost at your team size in twelve months, not today. A per-user plan with five people costs five times a single seat. Free plans can jump when you cross a cap. Pay-per-action costs depend on how many leads, emails and invoices you handle.
Be wary of free marketing. Many platforms advertise a free version but gate it behind hard user caps or turn it into a time-limited trial. Always check whether the free plan lets your team grow or forces the whole organisation to upgrade.
How many other tools it replaces
A CRM that is cheap but needs a separate quoting tool, invoicing app and email platform costs more in time than it saves in money. One study of CRM adoption notes that many small firms track customer interactions inside their accounting or ERP system, avoiding the tool sprawl of spreadsheets and standalone CRM apps. The same logic argues for a platform that already holds sales and finance together.
If quotes matter to you, our five real tests for CRM with quotes show how to check that the handoff from quote to invoice works.
Adoption, not features
Research on SME CRM adoption finds tension between the people who use the software and the vendor is normal. The most successful projects had an integrator, such as an IT manager or consultant, who made the system fit how the team works. You do not need a full-time person. You do need someone who owns the setup. If that is a consultant rather than an employee, a guide to CRM workflow automation for stalled deals shows the kind of follow-up rules worth setting up first.
Exit and data ownership
Ask before you sign: can I export every contact, note and deal? If the answer is vague, move on.
Our view: why we chose pay-per-action
We built OK Technology around one frustration. Small businesses end up paying for software they barely touch. A seat for the person who logs in once a month, a plan tier for one feature, a second tool because the first one lacks invoicing. Each is small, and together they are a tax on your week.
So we charge for actions. A lead is created, a wallet is debited. An invoice goes out, a wallet is debited. There are no tiers to climb and no seats to count. We think this is fairer for businesses with uneven months, such as hospitality firms with a seasonal peak, agencies with project spikes, or finance teams that bill in bursts.
We are also honest about where it does not fit. If you are a solo founder who only needs a contact list, a free plan from Zoho or HubSpot may be all you need today. If your volume is very high and flat, run the numbers against a per-user price. Where it shines is when you have outgrown your first tools and want one place for the customer record and the money that follows.
The cost of a CRM is rarely the licence. It is the hours spent copying data between systems. Remove the copying and the licence question gets simpler.

How to choose in four steps
- List your must-haves. Contacts, deals, email, quotes, invoices. Mark each as essential or nice to have.
- Shortlist two or three. One free option, one per-user option and one all-in-one is a good spread.
- Run a real week. Import fifty real contacts, log five real deals and send one real invoice. Time how long it takes.
- Price month twelve. Add the users you expect to have, the emails you expect to send and the storage you expect to need.
If you are a nonprofit, the answer changes. Donor records and stewardship reporting matter more than sales pipelines, and independent 2026 benchmarks point to dedicated tools such as Neon CRM, Little Green Light and Blackbaud Raiser's Edge NXT.

FAQ
What is the best CRM for a very small business?
For one to three people, a free plan such as Zoho CRM's is a sensible start, as it covers leads, contacts, accounts and deals. If you also want quotes, invoices and email in the same system, a platform like OK Technology avoids a second subscription. Pick based on what happens after the deal is won.
Is Zoho CRM really free?
Yes, but with limits. The free edition is permanent and needs no credit card, yet it is capped at 3 users and lacks custom modules and advanced reporting. Once you need a fourth user, your whole team must move to a paid edition.
Is pay-per-action cheaper than per-user pricing?
It depends on volume. With uneven or low activity, paying per lead, email or invoice usually costs less than paying for seats. With very high, steady activity, compare the monthly total with a per-user price before you decide.
Do I need a CRM if I only have a few customers?
A small customer list is not a reason to skip it. The value is in following up on time and keeping history in one place, not in the number of records. A simple free tool is enough to begin with.
