Short answer: whether an automation pays back depends entirely on your numbers — but the maths is simple enough to run yourself in ten minutes. Hours saved, times what those hours cost you, against what the automation costs to set up and run. This post shows you how, using five common automations for Australian SMBs: invoice chasing, lead follow-up, weekly reporting, data entry between systems, and appointment reminders.
To keep it concrete, we’ve run the arithmetic on an illustrative example business — a small service business where the owner and one admin person share the paperwork. The hours below are assumptions we’ve picked to make the maths easy to follow, not measured results from a client. Swap in your own hours and the same method gives you your own automation ROI. Your numbers will differ.
The maths: how to value an hour of admin
Before the five automations, two numbers you need:
Your loaded hourly cost. Not the wage — the real cost, including super, leave and overheads. Work yours out from your own payroll. In the example we’ll use $35/hour throughout, purely so the maths is easy to adjust. If it’s your evening and weekend time, the honest figure is usually higher.
The payback formula. Payback period = setup cost ÷ (monthly savings − monthly running costs). If an automation costs $500 to set up, saves $500/month of staff time and costs nothing extra to run, payback is one month. If it saves $200/month, it’s two and a half months. If the hours saved are close to zero, it never pays back — and that’s a perfectly good reason not to automate.
One more thing the spreadsheet misses: some automations change outcomes as well as hours — fewer data-entry errors, fewer missed appointments, faster replies to leads. Those are real but hard to predict, so the worked example counts time only. If you have your own figures for those (how many no-shows last quarter, how many quotes went unanswered), add them in; if you don’t, leave them out.
The five automations
1. Invoice chasing
Before: Someone — usually the owner — spends ~4 hours a week pulling the overdue list, writing “just following up” emails, logging who promised to pay when, and doing the awkward phone calls.
After: The accounting system sends a polite reminder sequence automatically at 3, 7 and 14 days overdue, escalates to a personal note only when ignored, and flags genuine disputes for a human. Human time: ~15 minutes a week.
Example time account: 4 hrs/week → 0.25 hrs. Roughly 15 hours a month, worth ~$525 at $35/hour.
Running the maths: Xero and MYOB both have automatic invoice reminders built in — if you’re on either, setup cost is close to $0 beyond an hour of configuration, so payback in the example is near-immediate. If you need per-client rules, approvals or escalation, that’s a bigger build; plug its cost into the formula instead. Reminders that go out on schedule can also bring cash in sooner, but that depends on your clients — check your own debtor days before and after rather than assuming it.
2. Lead follow-up
Before: ~5 hours a week manually replying to web enquiries, copying details into a spreadsheet or CRM, remembering to follow up quotes, and losing the ones that arrive at 9pm because nobody saw them until Tuesday.
After: Every enquiry gets an instant acknowledgement, lands in the CRM automatically, and triggers a follow-up sequence — quote sent day 1, nudge day 3, final check day 7 — until the lead converts or goes cold. Human time: ~30 minutes a week reviewing the pipeline.
Example time account: 5 hrs/week → 0.5 hrs. Roughly 18 hours a month, worth ~$630 at $35/hour.
Running the maths: A CRM with email automation (HubSpot’s free tier, or tools like ActiveCampaign at roughly $30–$100/month — pricing is approximate and moves around) covers most of this. Setup is a day or two of someone’s time. In the example, that’s a payback of a few weeks on time alone. Faster replies may also win jobs that slow replies lose — if you know what a won job is worth to you, work out how many extra you’d need for the numbers to stack up. If your leads come in through your website, pairing this with an after-hours chatbot captures the ones who never fill in the form at all.
3. Weekly reporting
Before: ~3 hours every Friday (or Monday in a panic) exporting numbers from three systems, pasting them into a spreadsheet, fixing the formatting, and emailing a report that’s already out of date.
After: A scheduled automation pulls the same numbers overnight, drops them into a live dashboard or a formatted email, and sends it at 7am. Human time: 10 minutes to actually read it.
Example time account: 3 hrs/week → 0.2 hrs. Roughly 11 hours a month, worth ~$385 at $35/hour.
Running the maths: Automation platforms like Make or Zapier handle this well — entry tiers run roughly $10–$30/month (approximate), plus a few hours to build the scenario. In the example, payback is a few weeks. There’s a less measurable upside too: when the report costs nothing to produce, it’s easier to actually look at it every week.
4. Data entry between systems
Before: ~6 hours a week re-typing the same information — enquiry details into the CRM, CRM into the quoting tool, quote into the invoice, invoice into the job sheet. Plus the monthly hour spent finding and fixing the typos.
After: Enter once, sync everywhere. A new enquiry creates the CRM record, the quote pulls from it, the accepted quote generates the invoice and job entry automatically. Human time: near zero, except genuine exceptions.
Example time account: 6 hrs/week → ~0. Roughly 24 hours a month, worth ~$840 at $35/hour.
Running the maths: In the example this is the biggest line, and it’s the one most worth doing properly. Simple two-system syncs are cheap (an automation platform scenario, as above). Multi-system flows with business rules — “only create the job if the deposit is paid” — cost more to build, so run the formula with the real quote. If you track how much time goes into fixing re-keying errors, add that in; if you don’t, it’s worth tracking for a month before you decide.
5. Appointment reminders
Before: ~2 hours a week calling or texting tomorrow’s clients to confirm — plus the cost of the no-shows that happen anyway.
After: Automatic SMS and email reminders go out 48 hours and 2 hours before each appointment, with a one-tap confirm or reschedule link. Human time: zero.
Example time account: 2 hrs/week → 0. Roughly 8 hours a month, worth ~$280 at $35/hour.
Running the maths: Most booking tools (Calendly, Cliniko, Square Appointments and similar) include reminders at roughly $15–$50/month (approximate), so in the example payback is quick. No-shows are the other side of it: count how many you had last quarter and what a missed slot costs you. If reminders prevented even one a month, you can see what that’s worth — but measure it on your own bookings rather than relying on someone else’s percentage.
The example, stacked up
Here’s the illustrative example business with all five side by side. Assumptions: $35/hour loaded cost, the weekly hours shown in the “Before” column, time savings only. These are example inputs, not results from a client — your numbers will differ.
| Automation | Before (example) | After (example) | Hours/mo (example) | $/mo at $35/hr | Typical setup cost | Example payback |
|---|---|---|---|---|---|---|
| Invoice chasing | 4 hrs/wk | 15 min/wk | ~15 | ~$525 | $0–$200 (built into Xero/MYOB) | Days–1 week |
| Lead follow-up | 5 hrs/wk | 30 min/wk | ~18 | ~$630 | $30–$100/mo tool + 1–2 days setup | A few weeks |
| Weekly reporting | 3 hrs/wk | 10 min/wk | ~11 | ~$385 | $10–$30/mo tool + a few hours | A few weeks |
| Data entry between systems | 6 hrs/wk | ~0 | ~24 | ~$840 | Cheap for simple syncs; more for multi-system flows | Depends on the build |
| Appointment reminders | 2 hrs/wk | 0 | ~8 | ~$280 | $15–$50/mo (approx) | Days |
In the example, that adds up to roughly 76 hours and ~$2,660 a month of staff time. That’s a product of the made-up inputs, not a prediction for your business.
Running it on your own numbers
The example is only useful as a template. To get your own figure:
- Time one normal week. Jot down how long each of these jobs actually takes. Guesses are usually off — in both directions.
- Estimate the “after” honestly. Most automations still leave some human time: approving drafts, handling exceptions, reading the report. Don’t assume zero.
- Multiply by your own loaded hourly rate.
- Subtract running costs — subscriptions, SMS fees, any monthly support.
- Divide the setup cost by what’s left. That’s your payback period in months.
If the answer is “a few weeks”, good. If it’s “two years”, that’s useful too — it means this one isn’t worth doing yet, or a cheaper tool would do. Bundling several automations into one build changes the setup cost and the saving together, so run the bundle as its own line rather than adding up the best cases.
DIY tools vs a done-for-you build
Everything above is achievable two ways, and the right choice depends on how your systems fit together.
DIY suits you when the automation is simple (one trigger, one action), your tools already talk to each other, and someone on the team enjoys this stuff. The risk is the same as any DIY: your time isn’t free, and a half-working Zap that silently stops syncing is worse than none.
Done-for-you makes sense when the flow crosses several systems, involves business rules, or touches money and customers — where a silent failure costs real dollars. Our Workflow Packs are fixed-scope builds for exactly this: Quote Follow-up ($1,490 + GST), Enquiry → Job ($1,990 + GST) and Invoice Chase ($1,490 + GST), each live in 5–10 business days with human approvals built in. Any three are $4,500 + GST, and bigger multi-system jobs are scoped as custom automation from $4,500 + GST. Optional Workflow Care from $190/month + GST covers fixes and small changes after launch — no retainer you didn’t ask for.
Whichever route you take, put the real price into the payback formula above before you commit.
A practical middle path: start with the free or cheap wins (invoice reminders, appointment reminders) yourself this week, and bring in a build for the multi-system flows where DIY gets fragile.
Which one are you?
- Drowning in overdue invoices or no-shows? Switch on the reminders already built into your accounting or booking software first — the cost is near zero, so there’s little to lose.
- Losing leads and Fridays to follow-up and reporting? A CRM plus an automation platform gets you most of the way for under $100/month (approximate) — set it up properly once.
- Re-typing enquiries into your job system, or chasing quotes and invoices by hand? That’s what the Workflow Packs are for — fixed scope from $1,490 + GST, live in 5–10 business days. Run the payback maths with that price first.
- Not sure which of your processes is worth automating? That’s exactly what our free 20-minute scoping call is for — bring your week, we’ll do the maths with you, and if the honest answer is “you don’t need automation yet”, we’ll tell you that too.
