How Much Should a Solopreneur Spend on Software? A Real Monthly Budget

Nobody decides to spend $400 a month on software. It happens one $29 subscription at a time, each of which felt obviously worth it on the day you signed up.

Then one afternoon you export your card statement, and there they are: the scheduler you replaced eight months ago but never cancelled, the design tool you use twice a year, two products that do the same thing because you migrated halfway and stopped.

No software vendor will publish an article telling you what a sensible ceiling looks like — it isn’t in their interest. So here is one, with actual line items at three revenue levels.

The Benchmark: 2–5% of Revenue

It’s a rough rule and it’s useful precisely because it’s rough.

Two things make the percentage work better than a flat number. It scales with the business rather than with your enthusiasm, and it forces a trade-off: adding a tool means either cutting one or growing revenue. That trade-off is the entire point.

Below 2%, you’re usually leaving leverage on the table — there’s almost certainly one subscription that would return more than it costs. Above 5%, in a one-person business, the extra spend is rarely buying capability. It’s buying things you signed up for and forgot.

A Worked Budget at $8,000/Month

Call the ceiling $320. Here’s a stack that fits inside it with room left over.

Notice what isn’t on the list: project management (you’re one person), a dedicated password manager tier above free, a second design tool, anything sold to you as “AI-powered” without a specific job to do.

The Four Categories That Earn Their Keep

1. Money in. Payments, invoicing, and books. This is the only category where paying more reliably returns more, because the failure mode is not getting paid. Don’t economise here.

2. Delivery. Whatever you actually use to make the thing clients pay for. Obvious, and worth stating because it’s the category people cut first when they panic — which is backwards.

3. The system of record. One place where the state of the business lives: clients, projects, what’s outstanding. Cheap, and the thing that stops you holding everything in your head. Our roundup of automation tools covers the usual candidates.

4. One connector. One. Not two “for now.” A single automation platform that everything else plugs into — see Zapier vs Make for which suits you. The cost here is small and the leverage is the largest in the stack.

Email and CRM sit just outside the four, because whether they earn their place depends entirely on how you sell. If you sell through a list, they’re essential — our guide covers that case. If you sell through referrals and calls, a free CRM covers you for years.

Consolidate, or Pick the Best of Each?

The recurring budget question, and there’s a real trade-off rather than a right answer.

Free Tiers That Are Genuinely Enough

Worth saying plainly, because the articles that usually answer this question earn more when you pay.

• A CRM. HubSpot’s free tier — unlimited users, a real pipeline — covers most freelancers for years. It pays us nothing and it’s still the default recommendation in our CRM comparison.
• A connector, for low volume. Make’s free plan includes the actual visual builder rather than a demo, and its monthly allowance covers a couple of event-driven automations comfortably — see how operations are counted to estimate your own.
• Forms, scheduling, basic storage. The free tiers here are good enough that paying is usually a convenience purchase, not a capability one.

Start every category on free. Upgrade when something breaks, not when you’re planning.
