AI & Workflow Automation
The inbox is quietly eating your day
Most bookkeeping firms don’t realise how much time disappears inside the email inbox. Opening messages, checking attachments, forwarding invoices, and following up on missing info can quietly add hours to every week. This article breaks down why email handling has become one of the biggest hidden time drains in accounts payable, especially for bookkeepers dealing with high invoice volumes. We look at how inbox work compounds, why forwarding emails creates friction, where tools like Dext and Hubdoc help but still fall short, and why inbox automation is becoming just as important as invoice automation for modern bookkeeping practices.

Ask any bookkeeper where time disappears and you’ll usually hear the same answer. Not reconciliations. Not BAS. Not even month end.
It’s the inbox.
Not the dramatic stuff either. Just the constant clicking. Open email. Download invoice. Check attachment. Realise it’s the wrong one. Forward it. Chase it. Follow up. Repeat. All day.
Most bookkeeping practices don’t think of email as a workflow problem. It feels too small, too obvious. But that’s exactly why it’s dangerous. Those tiny actions add up. Fast.
By the end of the week, the inbox has quietly stolen hours. By the end of the year, it’s taken weeks.
And no one ever budgets time for it.
Clicking emails doesn’t feel like work, but it is
Here’s the trap. Email handling feels light. Low effort. You’re not “doing accounting”. You’re just… moving things around.
But think about a typical supplier invoice journey.
An email arrives. You open it.
It has an attachment. Or maybe a link.
You download it.
You check who it’s for.
You forward it to Dext or Hubdoc.
Or save it and upload later.
Or forward it to a client asking where it belongs.
That’s already six or seven micro actions. None of them hard. All of them necessary.
Now multiply that by 50 invoices a day. Or 100. Or more during busy periods.
That’s where the time goes. Not in one big chunk. In a thousand tiny clicks.
And because it’s fragmented, it’s invisible.
Why inbox work hits bookkeepers harder than anyone admits
Bookkeepers sit at a weird crossroads.
Clients send documents however they feel like. Suppliers send invoices however they feel like. Accounting systems expect structure. Clean data. Clear rules.
Email is the messy middle.
Unlike AP teams inside a business, bookkeepers deal with dozens of inbox behaviours at once. Every client has their own habits.
Some forward everything.
Some send photos.
Some reply to old threads.
Some CC the whole office.
Some drip feed invoices across five emails.
There’s no standard. So the inbox becomes the sorting yard.
And every time you click, you context switch. You lose focus. You slow down without noticing.
That’s the real cost. Not just time, but mental load.
Forwarding emails sounds harmless. It isn’t.
Forwarding is one of those habits everyone accepts. It’s how things have always been done.
But forwarding creates hidden friction.
You have to decide where it goes.
You have to check the attachment went through.
You have to clean up your inbox after.
You have to remember if you’ve already sent it.
Miss one step and something slips.
Worse, forwarding trains clients into bad behaviour. They keep sending invoices however they want, because someone on your side will “sort it out”.
That someone is usually you.
And once forwarding becomes the norm, volume creeps up. Because there’s no resistance in the system.
The real math of inbox time
Let’s do some rough, honest maths.
Say it takes 30 seconds to properly handle an invoice email. Open, check, forward, close. That’s conservative.
20 invoices a day is 10 minutes.
40 invoices is 20 minutes.
80 invoices is 40 minutes.
Now multiply by five days.
That’s 3 to 4 hours a week. Per staff member. On email handling alone.
Over a year, that’s close to 200 hours.
Almost five full work weeks. Gone. On clicks.
And most practices have more than one person doing this.
Why “Inbox Zero” doesn’t actually solve it
A lot of bookkeepers try to fix the pain with discipline.
Inbox Zero.
Folders.
Rules.
Flags.
Those help with visibility. They don’t remove the work.
You’re still opening emails. You’re still touching every document manually. You’re just doing it in a more organised way.
It’s like rearranging your desk instead of reducing the pile of paperwork landing on it.
The core problem stays untouched.
Email wasn’t built for accounting workflows
Email is great at sending messages. It’s terrible at managing documents at scale.
There’s no structure.
No validation.
No context.
No confidence.
An email doesn’t know if an invoice is a duplicate.
It doesn’t know which client it belongs to.
It doesn’t know if GST is mixed.
It doesn’t know if freight should be split.
So a human has to decide every time.
That’s fine at low volume. At scale, it breaks.
And that’s why inbox work grows faster than revenue in many practices.
Where tools like Dext and Hubdoc helped… and where they stop
Tools like Dext and Hubdoc were a huge step forward. They solved the “how do I get documents into Xero” problem.
They reduced scanning. Reduced manual uploads. Reduced lost paperwork.
But they didn’t really remove the inbox. They shifted it.
Someone still has to forward emails.
Someone still has to decide what belongs where.
Someone still has to deal with the messy invoices after they land.
Especially the tricky stuff. Freight. Multi account bills. Mixed tax. Supplier weirdness.
So while capture improved, inbox handling stayed stubbornly manual.
That’s why many bookkeepers still feel busy even with modern tools.
The emotional tax no one talks about
There’s also the quiet stress of email.
The fear of missing something.
The dread of an unread inbox.
The mental note of “I’ll come back to that later”.
Email doesn’t respect focus time. It constantly pulls you out of flow.
And when your day is chopped into tiny reactive moments, it feels longer than it is.
You end up tired without feeling productive.
That’s not a tooling issue. It’s a workflow issue.
Why inbox automation matters more than invoice automation
Most software talks about invoice automation. OCR. Data extraction. Coding rules.
Those are important. But they happen after the inbox.
If email intake is slow, everything downstream slows too.
Think of the inbox as the front door to your practice. If people queue there, nothing else runs smoothly.
Fix the inbox and the rest suddenly feels lighter.
Not perfect. Just calmer.
What actually helps reduce inbox time
Not more discipline. Not more folders. Not more rules.
What helps is removing decisions from the inbox entirely.
When emails don’t need to be opened.
When attachments don’t need to be forwarded.
When documents are routed automatically.
That’s when time comes back.
The goal isn’t Inbox Zero. It’s Inbox Irrelevance.
You want emails to land, get handled, and move on without human touch.
The compounding effect for practices
Here’s the part most firms underestimate.
Inbox time grows faster than headcount.
Add more clients and email volume rises. Add more staff and coordination rises too.
Before long, you’re hiring people just to manage flow.
That’s when margins shrink. Not because fees are wrong, but because admin quietly expanded.
Fixing the inbox early changes the curve.
It lets practices grow without adding the same amount of internal drag.
Why this matters right now
Clients are sending more documents than ever.
E-commerce. Imports. Freight. Subscriptions. Split invoices. Mixed tax lines.
Invoice complexity has gone up. Email volume has followed.
But workflows haven’t caught up.
Bookkeepers feel it first. That’s why inbox pain shows up in every conversation, even if no one names it directly.
They just say they’re busy.
A quieter way to work
Imagine starting the day without opening your inbox first.
Invoices already routed.
Exceptions already flagged.
Only edge cases needing attention.
Email becomes communication again. Not a processing line.
That’s not a dream scenario. It’s just a different way of treating email.
As a system input. Not a human task list.
Final thought
Inbox work feels small. That’s why it’s dangerous.
It doesn’t scream for attention. It quietly steals it.
If you want to give bookkeepers time back, don’t start with reports or dashboards. Start with the clicks.
Remove enough of those and the whole day changes.
And once you see it, you can’t unsee it.
