How to stop retyping data between your systems

If someone in your business spends Monday morning copying orders from one screen into another, this guide is for you. Double data entry is one of the most common time sinks in a small business. It's also one of the easiest to fix. You rarely need new software. You usually need to connect what you already have, and take a few steps out first.

Your systems should talk to each other. Your people shouldn't be the cable. Here's how to stop double data entry, in plain English.

Why retyping data costs more than it looks

Retyping feels small. Ten minutes here, twenty there. But it costs you in three ways.

Time

Every manual copy is time someone isn't spending on customers, sales or going home on time. It's rarely one big job. It's lots of small ones spread across the week, which is why nobody notices.

Errors

People make typos. Not because they're careless, but because copying numbers is dull, and dull work invites mistakes. A swapped digit on an invoice or the wrong VAT code can take far longer to find than it took to make.

Trust

Once numbers have been through a few pairs of hands, people stop believing them. You end up with three versions of the customer list and a spreadsheet nobody wants to touch. Decisions slow down because nobody's sure which figure is right.

Tax

There's a compliance angle too. Making Tax Digital for VAT expects the figures on your VAT return to flow through digital links from your records. Retyping or copying and pasting figures between your records and your return isn't generally treated as a digital link. If your VAT process involves rekeying numbers into a spreadsheet before you submit, read HMRC's VAT Notice 700/22 or ask your accountant. Making Tax Digital for Income Tax, which started in April 2026 for sole traders and landlords above an income threshold, pushes in the same direction.

Step 1: find where the retyping happens

You can't fix what you haven't spotted. For a week or two, ask everyone to note each time they copy information from one place to another. Keep it light. A shared spreadsheet with five columns does the job:

What was copied (orders, timesheets, invoices, stock counts)
Where it came from
Where it went
How often it happens (daily, weekly, monthly)
Roughly how many minutes it takes each time

If you're not sure where to look, start here:

Online orders typed into the accounts system
Timesheets rekeyed into payroll before the PAYE run
Supplier invoices typed in from PDFs
Customer details copied from an enquiry form into a CRM, then again into the invoicing tool
Stock levels updated by hand in two places
Month-end reports built by pasting exports into a spreadsheet

Ask the people doing the work, not just the managers. They know where the copying happens. Managers often don't.

Step 2: work out what it costs

Now put a number on each job. The sum is simple:

minutes each time × times per week × 52 ÷ 60 = hours per year

Then multiply the hours by what that person costs you per hour. Use their salary plus employer's National Insurance and pension, divided by the hours they actually work in a year. That's the direct cost.

Here's an illustration, not a benchmark. If someone spends 20 minutes a day, five days a week, copying orders, that's 20 × 5 × 52 ÷ 60, or about 87 hours a year. Plug in your own figures. Then add a rough allowance for time spent finding and fixing errors, because that part is usually bigger than people expect.

You'll end up with a short list of jobs and a cost against each. The biggest numbers go first. We go deeper on measuring this in the hidden cost of manual processes.

Step 3: remove steps before connecting anything

This is the step most people skip. Before you connect two systems, ask whether the data needs to move at all.

Is anyone still reading the report you're building? If not, stop building it.
Do you need the same information in two places, or could one system be the single source?
Are you capturing details nobody ever uses?
Could the customer enter it themselves, for example through an online form that feeds straight into your system?

Connecting a messy process just makes the mess move faster. Tidy it first. Sometimes this step alone gets rid of half the list.

Step 4: pick the right way to connect

Once you know what needs to move, there are roughly four ways to do it, from simplest to most involved.

Use the connections your software already has

Most cloud accounting tools, including Xero, QuickBooks Online and Sage, have app marketplaces with ready-made connections to e-commerce platforms, payroll, CRM, expenses and more. Bank feeds are the obvious example: transactions arrive in your accounts software without anyone typing them. Check what you already pay for before you buy anything new. Plenty of businesses have a connection available and simply haven't switched it on.

Invoice and receipt capture

For supplier bills, there are tools that read invoices from an email inbox or a photo and post them to your accounts software. You still check them. But checking is quicker than keying, and it's a far less tedious job.

Connector tools

Tools like Zapier and Make sit between apps and move data when something happens: a new order, a form submission, a signed contract. They're good for simple, well-defined flows. They do need someone to look after them, and they get messy if you build lots of them without a plan.

Direct API connections

Most cloud software has an API, which is a documented way for other software to send and receive data. A direct connection built on those APIs gives you the most control, especially when the data needs reshaping on the way through or volumes are high. It takes more setup and needs looking after, so it makes sense when off-the-shelf options don't fit.

Step 5: test it, then trust it

Don't switch everything over on a Monday and hope for the best.

Run the new connection alongside the old manual process for a few weeks.
Compare the results. Do the totals match? Are VAT codes right? Do customer records line up?
Decide who owns the connection. Someone needs to know when it fails, and what to do about it.
Write a short note: what moves, when, and where to look if it stops. One page is plenty.
Then switch off the manual process. Properly. If people keep a shadow spreadsheet "just in case", you've doubled the work, not halved it.

Mistakes to avoid

Buying new software to fix a process problem. New software brings new retyping if nobody plans how it connects to the rest.
Connecting everything at once. Start with the job that costs the most. Get it working. Then do the next one.
No owner. Connections break. Passwords change, apps update, someone renames a field. Make sure a named person gets the alert.
Ignoring data quality. If your customer list has duplicates, connecting it to another system copies the duplicates. Clean it first.
Forgetting your accountant. Changes to how sales and costs reach your books affect VAT and year-end. Tell them before, not after.

What good looks like

When it's working, you notice the things that stop happening. Nobody spends Monday copying orders. Month-end takes less time. The numbers in your accounts match the numbers in your sales platform without a fight. Your team gets back hours they can spend on work that actually needs a person.

The test is simple: type it once. If a piece of information gets typed more than once, there's probably a way to connect it.
