Guide / the minimal stack
What software does a small business need?
Less than the internet says, more than a spreadsheet — and in a specific order: the books first, the operational record second, everything else on evidence. Here is the minimal stack, phase by phase.
The key facts
- Phase 1, non-negotiable: accounting software — compliance is not optional, and the spreadsheet chapter of the books ends early.
- Phase 2, when stock or orders are daily: the operational record — inventory, purchasing, orders, invoicing on one system.
- Phase 3, on evidence: customer tools, marketing, workforce — bought when the failure they fix exists, not before.
- BSimple's place: phase 2 for stock-carrying businesses — one record from $180/month AUD, with the books left to the accounting software.
- The wider system: inventory management end to end maps the whole record this page sits in.

Phase 1 — the books (non-negotiable)
The first software a small business needs is accounting software, and the reason is regulatory, not fashionable: tax obligations arrive on day one, and the books are how they get met. In Australia that usually means Xero or MYOB; the choice matters less than committing early, because every month of retro-books is a month of reconstruction. Everything else on this page is optional by comparison — this one is not, and any advisor will tell you the same.
Phase 2 — the operational record (when stock is daily work)
The second need arrives when stock, orders or purchasing become daily work — usually invisibly, through a spreadsheet that a second person now edits. The record a business needs at this stage is one system holding: live quantities across every location, orders that deduct stock when they are approved, purchase orders raised from demand against reorder levels, and invoices that reach the accounting software without re-entry. Batch tracking, customer portals and reporting grow from that record rather than arriving as separate subsystems.
The failure of skipping phase 2 is quiet until it is loud: oversells, counts that surprise everyone, month-end reconstructions that eat a day. We build BSimple, so weigh that — it is exactly this layer for wholesale, manufacturing, distribution and trade businesses: $180/$250/$399 per month AUD, every feature in the core plans, browser-based, with the trial as the test on your real products.
Phase 3 — everything else, on evidence
Customer tools — CRM for pursuit, email and SMS for retention — earn their place when the business has more prospects than it can remember or more customers than it can chase. Workforce tools arrive with payroll complexity and rosters. Marketing, booking, scheduling and industry-specific tools arrive with the failure they fix. The discipline that keeps phase 3 cheap: name the failure first, then buy the smallest tool that fixes it — and prefer tools that connect to the record over tools that create a second one.
The full shelf, sorted by job rather than phase, is in small business software solutions; the business software definition explains the record layer; apps for business management covers the mobile angle; and the list of business management software types maps the variants.
Frequently Asked Questions
What software does a small business actually need?
Accounting first, always. Then an operational record if stock or orders are daily work. Everything else — CRM, marketing, workforce — on evidence: a named failure, then the smallest tool that fixes it.
Can we run on spreadsheets a bit longer?
For the books, no — the tax office does not accept cleverness. For operations, yes, honestly, until the second person edits the sheet or the first oversell lands; then the record pays for itself.
Is BSimple needed from day one?
If stock and orders are daily work from day one — importing, producing, distributing — then yes, it is the phase-2 layer and the trial is cheap to run early. If not, stay on the spreadsheet phase without guilt.
How do we avoid buying software we do not need?
Buy per failure, not per feature: write down what went wrong this month, buy the tool that fixes that failure, and prefer whatever connects to the record you already keep.
What does the phase-2 layer cost?
BSimple runs $180/$250/$399 per month AUD flat with everything included. The honest comparison is the spreadsheet's hidden schedule — oversells, re-keying, surprise stocktakes — which is rarely zero.
