The best tech stack for your small business on any budget

One of the questions I get asked most is "what should I actually use to run my business?" And the answer depends almost entirely on your budget and how much you want to manage. You don't need expensive software to look professional and get paid, but you do need every essential covered, because a missing piece is usually where clients slip through.

So here are three tech stacks I'd happily recommend: one that costs next to nothing, one all-in-one platform that sits in the middle and one premium set-up for people who want the best tool for each job. Every one of them covers the same essentials.

The essentials every service business needs

Whatever you spend, your tech should handle these jobs:

• A home online where people can find out what you do
• Bookings so clients can grab a call without ten emails back and forth
• Forms for enquiries, onboarding and feedback
• Contracts and proposals that clients can sign online
• Email marketing so you can stay in touch with people who aren't ready to buy yet
• A way to take payment for your services or products

A quick note before we start: some of the links below are affiliate or partner links, which means I may earn a commission if you sign up, at no extra cost to you. I only recommend tools I'd suggest to a client anyway. Prices are as at September 2026. These platforms bill in US dollars, so the pound equivalent is in brackets at roughly £1 = $1.35.

Stack one: the almost free stack

If you're just starting out or keeping costs as low as possible, this combination is hard to beat. All four tools have free plans, and each one has offered a one-off lifetime deal, so you can pay once instead of every month.

TidyCal for bookings

TidyCal gives you a simple booking page for discovery calls, sessions and consultations. It syncs with Google, Microsoft and Apple calendars so you never get double-booked, sends reminders to cut no-shows and takes payment through Stripe or PayPal when someone books a paid session. You can also sell packages of sessions. There's a free plan, and the lifetime deal has been around $29 (about £21).

FormRobin for forms

FormRobin is a form builder for enquiry forms, client questionnaires, onboarding forms and feedback. You can style forms to match your brand, see where people drop off and connect them to your email list or other tools. The free plan includes unlimited forms and responses, which is generous, and the lifetime deal is around $19 (about £14).

BreezeDoc for contracts

BreezeDoc lets you send contracts and proposals for clients to sign online, with no account needed on their side. You can track when a document has been opened and signed, use templates and even collect payment through Stripe or PayPal. The free plan covers 10 documents a month, which is plenty for most small service businesses, and paid lifetime plans start at around $19 (about £14).

SendFox for email marketing

SendFox handles your newsletter, sign-up forms and simple automations. The free plan covers up to 1,000 contacts, and the lifetime deal of around $29 (about £21) takes you to 5,000 contacts. It's simple rather than fancy, but it does the job well.

What this stack doesn't cover

There's no website builder here, and taking payment for products is limited. If you need a proper website, a sales page or a checkout on this budget, the free plan of the next platform is the easiest way to fill the gap.

Rough cost: free to start, or around $100 (about £74) once if you buy all four lifetime deals.

Stack two: one platform that does it all

This is the one I recommend to most of my clients, and it's what my own business runs on. Systeme.io is an all-in-one platform, which means your website, emails, funnels and checkout all live in the same place and talk to each other without any extra tools or connectors.

I'm Systeme.io certified, so I know this platform inside out, and this is what it covers:

• Website and blog on your own domain
• Sales funnels including landing pages, opt-in pages, sales pages and thank-you pages
• Email marketing with unlimited emails, newsletters and automated sequences
• Automations and workflows that tag people, send emails and grant access based on what they do
• Checkout and payments through Stripe and PayPal, with order bumps and upsells, and no transaction fees taken by Systeme.io (Stripe and PayPal still charge their usual fees)
• Online courses and communities for selling programmes or memberships
• A booking calendar so clients can book calls
• Your own affiliate programme so other people can promote your products
• Evergreen webinars on the higher plans

The free plan includes up to 2,000 contacts, three funnels, a blog, a course and unlimited emails, which is enough to build and launch properly before you pay anything. Paid plans start at $17 a month (about £13) for 5,000 contacts and unlimited funnels, then $47 (about £35) and $97 (about £72) as you grow.

The big advantage is that nothing needs to sync. When someone buys, they're tagged, emailed and given access automatically, all in one system. The trade-off is that design flexibility isn't quite as free-form as a dedicated website builder, but for most service businesses that's a small price for having everything connected.

Rough cost: free to start, then from $17 a month (about £13). You can still add BreezeDoc for contracts, since Systeme.io doesn't do e-signatures.

Stack three: the best tool for each job

If you want a completely custom-designed website and you're happy to connect a few separate tools, this premium stack gives you a lot of polish. It costs more and takes more set-up, but each tool is excellent at what it does.

Showit for your website

Showit is a drag-and-drop website builder that gives you real design freedom, with separate control over how your site looks on desktop and mobile. It's popular with photographers, coaches and creative businesses who want a site that feels bespoke. Plans start at $27 a month (about £20), or $34 a month (about £25) with a blog.

ThriveCart for selling

ThriveCart handles your checkout pages, order bumps, one-click upsells, subscriptions and payment plans. It also includes a course platform, and the Pro version adds an affiliate centre. It's usually sold as a one-off lifetime payment rather than a subscription, so it costs more upfront but nothing monthly.

Flodesk for email marketing

Flodesk is known for beautiful email templates that make your newsletters look designed, even if you're not a designer. It includes forms, landing pages and automated workflows, and higher plans add checkouts and sales pages. Paid plans start at around $25 a month (about £18) and increase as your list grows.

For bookings and contracts in this stack, TidyCal and BreezeDoc from stack one slot in perfectly.

Rough cost: around $50 to $80 a month (about £37 to £59) plus a one-off ThriveCart payment, before bookings and contracts.

So which one should you choose?

• Choose the almost free stack if you're just starting out, testing an idea or keeping costs to an absolute minimum.
• Choose Systeme.io if you want everything connected, you'd rather not manage integrations and you want a funnel and email sequence working together from day one. For most service businesses, this is the one.
• Choose the premium stack if a fully custom design is a priority, you have the budget and you're comfortable connecting separate tools.

Whichever you pick, the tools only matter if they're set up to work together. A beautiful website with no follow-up emails, or a funnel that doesn't connect to your checkout, will still leak clients. That's the part I help with.
