Running a small business means wearing every hat: salesperson, cashier, bookkeeper and marketer. The right apps take some of those jobs off your plate, but the wrong mix leaves you paying for overlapping tools you barely use. Most owners need a few things done well: following up with customers, getting paid, and keeping the books straight.

This guide picks one strong app for each of those jobs and starts with the one that brings money in. It explains how each app charges in broad terms, where fees creep in, and which ones you can skip until your business grows.

Best overall
Clinch

A simple sales tracker for leads, follow-ups and commission

0

Keeps every lead, follow-up and quote on your iPhone, so an owner who sells never lets a customer go cold.

For many small businesses, sales follow-up is the job that slips first. Clinch keeps it under control without adding admin. When someone asks for a price, you add them as a lead with the items and total, send a PDF quote from the app, and set a reminder to follow up. When they buy, you mark it sold. Contractors, home services firms and anyone who quotes before they sell will feel at home.
Lost jobs do not vanish: Clinch brings them back as reminders months later, which gives you a natural reason to check in again. There is no setup, no account and no cost, and the data stays on your phone. The honest limits: Clinch is for one person, with no team sharing, email integration or automation, and it does not handle payments or accounting, which is where the next picks come in.

Good for
Owners and solo sellers who quote, follow up and close deals themselves

Watch out for
One person only, with no team sharing or email integration

Best for selling online
Shopify

All-in-one platform to build and run an online store

0

The easiest way to launch and run a professional online store, with checkout, hosting and in-person sales included.

Shopify takes care of the technical side of selling online. You pick a theme, add products and get a professional-looking store with hosting, security and checkout handled for you. Shop Pay speeds up checkout for buyers, and the app store covers shipping, marketing and much more. If you also sell at markets or in a shop, Shopify POS runs in-person sales from the same system.
The Sidekick AI assistant helps with setup and reporting, which is handy when you are doing everything yourself. The catch is cost creep. Shopify is a subscription with a free trial but no free plan, monthly app fees add up, premium themes cost extra, and you pay extra transaction fees if you skip Shopify Payments. If you sell only a few items, a simple payment link may be enough.

Good for
Brands and makers who want to sell online without technical work

Watch out for
App fees and extra transaction fees add up quickly

Best for payments
Square

Point of sale and payments for shops, cafes and services

0

A free point-of-sale app and simple card readers that let a shop, cafe or service business take payments right away.

Square is the quickest way to start taking card payments in person. The free point-of-sale app handles sales, receipts, inventory and a customer list, and the hardware is easy to set up and pleasant to use. As you grow, you can add online ordering, appointments, invoices, payroll and loyalty without switching systems. Offline mode keeps card payments going when your connection drops.
There is no monthly fee to start, which suits a new business. Instead, you pay a processing fee on every card sale, so costs rise with your revenue. Advanced features for restaurants and retail need paid plans, and offline payments carry the risk of a later decline. For a cafe, salon, market stall or trades business, it is still the simplest way to get paid.

Good for
Shops, cafes and service businesses that take payments in person

Watch out for
A processing fee applies to every card payment

Best for accounting
QuickBooks

Small-business accounting, invoicing and payroll

0

Full small-business accounting that connects to your bank, sends invoices and handles payroll and sales tax.

QuickBooks is the accounting software accountants know best, which makes tax time much easier. It connects to your bank, categorizes transactions, tracks expenses and mileage, and sends invoices your customers can pay online. Payroll and sales tax tools are available, and you can invite your accountant to work in your books without using one of your paid seats. AI agents now help with bookkeeping and chasing late payments.
The catch is what it costs to keep running. QuickBooks is a subscription, prices have risen steadily, upselling is frequent, and payroll costs extra. The interface can also feel cluttered and slow. If you are a freelancer with a handful of simple invoices, it may be more than you need. For a business with staff, sales tax and an accountant, it is the safe choice.

Good for
Small businesses that want accounting their accountant can work in

Watch out for
Price increases and upsells, and payroll costs extra

Best for growing teams
HubSpot CRM

Free CRM that grows into a full marketing and sales suite

0

A free shared CRM with email tracking, forms and live chat for when more than one person handles customers.

HubSpot CRM is the next step when your business has more than one person talking to customers. The free tools give everyone shared contacts and deals, plus email tracking, meeting links, website forms and live chat. That means a lead who fills in a form on your site lands in the same place your team follows up from. The interface is clean, so staff tend to adopt it quickly.
Paid hubs add marketing automation, sales sequences, customer service tools and Breeze AI agents as you grow. The catch is that those tiers get expensive fast, and pricing based on marketing contacts can surprise you. The free tools have no time limit, so you can stay on them as long as they cover your needs. If you are the only one selling, Clinch is simpler.

Good for
Small businesses with a few people handling sales and support

Watch out for
Paid tiers get expensive, and contact pricing can surprise you

What should you look for in apps for a small business?

Start with the jobs that bring in or protect money: following up with customers, getting paid and keeping your books clean. Pick one app per job and resist adding more until a real problem appears. Apps that do one thing well are easier to learn and easier to drop if they stop fitting, which matters when you have little time for training.

Then look closely at how each app charges. Some are free, some are subscriptions, and payment apps take a fee on each sale. Add-ons and app store extras can add a lot to what you expected to pay, so check the full cost of the features you actually need. Finally, make sure your data can come with you, since exports and accountant access protect you if you switch later.

Which small business apps should you start with?

Start with the app that matches how you make money. If you sell by quote and follow-up, start with Clinch. If you sell products online, start with Shopify, and if you take payments in person, start with Square. Add QuickBooks once you have regular income and expenses to track, or before you hire staff. Add HubSpot when more than one person needs to see the same customers.

Frequently asked questions

What is the best free app for a small business?

Clinch is the best free app for owners who sell, covering leads, follow-ups, quotes and commission on iPhone. The Square point-of-sale app and the HubSpot CRM also have free plans, though Square charges a fee on each card payment.

Is Clinch or Shopify better for a small business?

They do different jobs. Clinch helps you follow up with leads and close sales you make in person or by phone, while Shopify runs an online store. Businesses that quote for work need Clinch, and businesses that ship products need Shopify.

Do I need QuickBooks for a small business?

Not on day one, but most businesses need proper accounting once income, expenses and taxes start to add up. QuickBooks is widely used by accountants, who can work in your books directly.

Is Square or Shopify better for in-person sales?

Square is simpler for businesses that mostly sell in person, since its point-of-sale app is free to start. Shopify POS makes more sense if most of your sales happen online and you want one system for both.
