· 6 min readHow to spot re-keying in your business, the small automations that stop it, and how to keep them documented, owned and easy to live with.

A new customer fills in the enquiry form on your website. Someone copies their details into the CRM. Later, when the job is confirmed, someone else types the same name, address and email into the accounts system to raise an invoice. Then a third person adds the job to the schedule in a shared spreadsheet.
None of it is difficult, and nobody minds doing it. But it's the same information typed three times, by three people, with three chances for a digit to slip. Multiply that across a week and it quietly adds up.
The good news is that most of the systems small businesses use can now pass information to each other, and many of the tools to do it are already included in what you pay for. This article explains how to spot the re-keying worth fixing, what small automations look like in practice, and how to keep them tidy so they stay helpful.
The best automations start from a small, specific annoyance, not from a tool. A useful exercise is to follow one piece of information through the business and note every time a person copies it from one place to another.
Good signs that a task is worth automating:
Ask the team, too. The people doing the work usually know exactly which bits are tedious, and they'll often have a clear idea of how it should work.
An automation, in this sense, is a simple rule: when something happens in one app, do something in another. "When a form is submitted, add a row to this list and email the office manager." No code, and usually a handful of steps.
Some everyday examples:
| The task today | A small automation |
|---|---|
| Enquiry form details copied into the CRM | New form responses create a contact or lead automatically |
| Supplier invoices forwarded from a shared inbox and filed by hand | Attachments from that inbox are saved to the right folder, and the accounts person is notified |
| A new starter's accounts and equipment requested by several emails | One form starts a checklist and lets each person know their part |
| Customers emailed by hand when an order ships | The shipping update triggers a friendly confirmation email |
| Someone checks a spreadsheet each Monday for overdue items | A weekly reminder lists anything past its date |
Each one saves a few minutes at a time. The bigger benefit is often consistency: the step always happens, in the same way, without relying on someone remembering.
There are three broad routes, and many businesses use a mix.
Built-in integrations. Before reaching for anything else, check whether your systems already talk to each other. Many accounting, CRM, booking and e-commerce systems have ready-made connections listed in their own app marketplace or settings. These are usually the simplest and most reliable option, because the vendor maintains them.
Automation built into Microsoft 365 or Google Workspace. If you use Microsoft 365, Power Automate is worth a look. Microsoft's licensing FAQ confirms that the Business Basic, Standard and Premium plans include Power Automate for flows that use standard connectors, which cover everyday Microsoft apps such as Outlook, SharePoint, OneDrive, Excel, Teams and Forms. Connecting to many non-Microsoft systems uses "premium" connectors, which need a paid Power Automate licence. We supply Microsoft licences and know these tools well, but the right choice depends on your business.
If you use Google Workspace, Google launched Workspace Studio in December 2025 for building automations across Gmail, Drive, Sheets and other Workspace apps, with connections to some third-party services. Google lists it as available on its Business Starter, Standard and Plus editions, among others.
Standalone automation services. Tools such as Zapier and Make connect thousands of apps and are popular with small businesses because they're quick to set up. Both offer a free plan for trying things out. At the time of writing, Zapier's free plan covers 100 tasks a month with two-step automations, and Make's covers up to 1,000 credits a month with two active scenarios. Paid plans are priced on usage, so it's worth estimating how often an automation will run before committing.
There's no single right answer. A business that lives in Microsoft 365 will often start with Power Automate. One whose key systems are a mix of specialist apps may find a standalone service easier. The best choice is usually the one that connects your particular systems with the fewest moving parts.
Small automations are easy to create, which is both their strength and their risk. A year later, nobody remembers who set up the flow that emails customers, or why it stopped working when someone left.
A few simple habits keep things healthy:
This is ordinary housekeeping, much like the file tidying we described in getting your business information ready for AI, and it pays off in the same way.
Off-the-shelf automation tools handle a great deal, and they're the right place to start. Sometimes, though, a process outgrows them. Signs to look out for:
At that point, a properly designed integration, built and documented as a small piece of software, can be simpler and more dependable overall. That doesn't mean starting again. The list of automations you've kept and the processes you've mapped are exactly what a good integration is built from.
You may also have heard about AI agents, which can take on more varied tasks than a fixed rule. They're promising, and we'll cover them soon, but for most re-keying problems a simple, predictable automation is still the better first tool.
This week, pick one piece of information that moves through your business, such as a new enquiry or a supplier invoice, and follow it from start to finish. Write down every point where someone types or copies it.
Then choose the single most repetitive step and check whether your systems already offer a built-in integration for it. If not, try building it in the automation tool that fits your setup, using a test record first. Add it to your list, with an owner, and see how it feels after a month.
If you'd like help finding the automations that will make the most difference, or connecting systems that don't quite fit together, our Software & Integration service is a good place to start, and we're always happy to talk it through.
