The business tower · the atrium
Accounting software, CRM and project tools
This is the entrance to the business tower. Accounting software, somewhere to keep customers, something to manage the work, and a way to send email that is not your own mailbox.
The tower is written for a specific reader: one person, or a very small team, choosing tools for the first time and paying for them personally. That matters, because almost everything published in this field is written for companies with a procurement process, and the advice is different. A feature that is essential at two hundred employees is dead weight at two.
Every floor therefore leads with the same three questions. What does it cost when the discount ends? What happens to your data if you leave? And is the free tier a real product or a fourteen-day corridor into a paid one? Those decide more small-business outcomes than any feature comparison, and they are the questions the vendors answer least clearly.
The accounting wing carries an additional caution that is repeated on every floor in it. What your business is legally required to record, keep and submit is set by the country you are in, it is not a software question, and no page here substitutes for an accountant. The floors describe what the tools do; they do not tell anybody what their obligations are.
The rest of the tower is less regulated and more forgiving. Customer records, project tracking and email marketing are all fields where the free options are genuinely usable for a long time, and where the most common mistake is buying too much too early.
Three levels, and you are on the first. This atrium lists the floors; a floor covers one subject completely and holds the shorter guides underneath it. Nothing here is more than three clicks from the front door.
Where to start
Seven ways in. Most first-time readers need the first and then the third.
- “I need to send invoices and track what I am owed.”
- Start at money
- “My customers live in a spreadsheet and it is chaos.”
- Go to customers
- “I cannot keep track of what needs doing.”
- That is managing the work
- “I want to email my customers properly.”
- That is reaching people
- “What can I run for nothing while I start out?”
- Every wing has a free floor — begin at money
- “I am already paying for too many subscriptions.”
- Read the last floor of managing the work
- “I need to get my data out of something.”
- Every floor answers that — customers
Money
Invoicing, accounts and getting paid. The floors with legal weight, and the ones where the cost of choosing badly is measured in an accountant’s hours rather than in a subscription.
Customers
Somewhere for the people you work with to live. The wing where the most money is wasted, because CRM is sold to small businesses that needed a well-organised spreadsheet.
Managing the work
Tasks, projects and time. The most crowded category in software, where nearly every tool works and the real question is which one your team will still be using in March.
Reaching people
Email marketing and the rules attached to it. One floor here is entirely about consent, because sending business email to people is a regulated activity nearly everywhere.
What this tower will not do
It will not tell a sole trader to buy enterprise software. Most of what ranks for these searches is written for companies with procurement departments, and applying that advice to a one-person business is how people end up paying monthly for capability they will never use.
It will not give tax or legal advice. The accounting floors describe what tools do and stop there; what you are required to record and submit depends on where you are and belongs to an accountant.
It will not rank these tools yet. Business software has to be lived with — through a month end, through a support request, through an export — and a verdict before that is just a rearranged feature list.
And it will not carry affiliate links. Business software pays the highest recurring commissions in the entire industry, which is exactly why the recommendations here have to be free of them.
A closing note on sequence, because the order of these decisions matters more than the decisions themselves. Start with the tool that has a legal deadline attached to it, which is the accounting one, and set it up properly before anything else. Then add whatever removes the thing currently costing you the most hours. Everything else can wait, probably for a year, and often forever. The most common pattern this tower is written against is a new business subscribing to five services in its first month, using two of them, and discovering at renewal that the introductory prices have all ended at once. What holds instead is simple: every floor answers what it costs at renewal and what happens to your data if you leave.
