The Hardest Part About E-commerce Bookkeeping (And Why It Never Seems to Get Easier)

Ask any bookkeeper who works with e-commerce clients what makes the job hard, and you’ll get a long pause.

Not because they don’t know the answer.
Because there isn’t just one.

E-commerce bookkeeping looks simple from the outside. No cash drawers. Mostly digital. Everything “should” be automated by now, right?

And yet, the clients with Shopify stores, Amazon accounts, 3PLs, and overseas suppliers are often the ones generating the most cleanup, the most rework, and the most late nights.

So what’s actually the hardest part?

It’s not the volume alone.
It’s not GST or sales tax by itself.
It’s not even reconciliations.

The hardest part is managing messy reality inside systems that were designed for tidy invoices.

Let’s talk about why.

It starts with volume. But volume isn’t the real problem.

Yes, e-commerce businesses generate a lot of transactions.

Hundreds or thousands of supplier invoices a month.
Payment processors batching payouts.
Ad platforms sending summaries instead of invoices.
Freight bills arriving separately, late, or not at all.

That alone stretches a traditional bookkeeping workflow.

But volume is solvable.
OCR can read documents faster than humans.
Bank feeds can pull transactions automatically.

If volume were the only issue, e-commerce bookkeeping would already be easy.

It isn’t.

The real pain lives in the exceptions

What actually slows bookkeepers down is not the invoices that go straight through.

It’s the ones that don’t.

And e-commerce has more of those than almost any other business model.

Think about a typical month.

You’ll see invoices with:

• Freight split across multiple cost accounts

• Mixed tax treatments on the same bill

• Inventory, landed costs, and services combined

• Foreign currency charges plus FX fees

• Bills that don’t match purchase orders cleanly

• Credits that arrive weeks after the original invoice

These aren’t edge cases.
They’re the norm.

And every exception breaks automation.

Freight is the quiet killer

Freight alone deserves its own chapter in the e-commerce bookkeeping pain story.

You’ll often get:

• One supplier invoice for goods

• A separate invoice for shipping

• Another for customs or duties

• And sometimes a consolidated monthly freight statement

None of it lines up neatly.

The bookkeeper has to decide:

• What portion goes to COGS

• What portion is inventory

• What portion is expensed

• How to allocate freight across multiple SKUs or POs

Most invoice capture tools weren’t built for this level of judgment.

They’ll extract the total.
Maybe the supplier.
Sometimes the tax.

But the thinking still sits with the human.

Multi-channel selling makes bookkeeping nonlinear

E-commerce businesses rarely sell through just one channel.

They’re on Shopify.
Then Amazon.
Then eBay.
Then wholesale.
Then marketplaces that send reports instead of invoices.

Each channel behaves differently.

Sales timing differs.
Fees are reported differently.
Payouts are batched.
Refunds lag.
Chargebacks arrive out of nowhere.

So the bookkeeping workflow stops being linear.

You’re no longer matching one invoice to one payment.
You’re reconciling summaries, timing differences, and partial information.

And that’s where even experienced bookkeepers slow down.

Inventory adds a second layer of complexity

Inventory is where bookkeeping stops being “admin” and starts being accounting.

With e-commerce, inventory isn’t static.

Prices change.
Shipping costs fluctuate.
Suppliers change terms.
Currency moves.
Stock arrives late or early.

That means:

• Landed cost calculations change month to month

• Margins can’t be trusted without clean data

• One bad allocation ripples through reports

Bookkeepers often end up doing cleanup work not because they made a mistake, but because upstream data changed after the fact.

That’s exhausting.

Why OCR tools struggle here

Tools like Dext and Hubdoc do a solid job at what they were designed for.

They capture documents.
They extract totals.
They reduce manual data entry.

But e-commerce bookkeeping doesn’t fail at data entry.
It fails at decision-making.

OCR can’t:

• Decide how to split freight across accounts

• Detect when tax treatments vary line by line

• Understand that the same supplier behaves differently across invoices

• Handle confidence. Was this coded right, or just “probably fine”?

So bookkeepers still review.
Still adjust.
Still fix.
Still reprocess.

Which brings us to the real bottleneck.

Review time quietly eats your margin

Most bookkeepers price e-commerce clients based on volume.

But volume doesn’t reflect effort.

A client with 300 clean invoices can be easier than one with 80 messy ones.

The problem is that review time isn’t obvious upfront.

You only feel it at month-end.
Or worse, during BAS.
Or when the client asks why margins look wrong again.

So bookkeepers either:

• Absorb the extra work

• Under-quote unknowingly

• Or spend their days firefighting instead of advising

None of those scale well.

Why e-commerce bookkeeping feels mentally heavier

There’s another layer people don’t talk about much.

Cognitive load.

E-commerce bookkeeping requires constant context switching.

One minute you’re thinking about GST on imported goods.
Next minute you’re reconciling Shopify payouts.
Then you’re splitting freight across SKUs.
Then fixing a PO mismatch.
Then answering a client Slack message.

Even with automation, the mental effort stays high.

That’s why e-commerce clients are often the ones bookkeepers feel “drained” by, even if the invoice count isn’t massive.

Where bookkeeping AI actually helps (and where it doesn’t)

Bookkeeping AI is often pitched as a silver bullet.

It isn’t.

But when it’s applied to the right problem, it does help.

AI works best when it:

• Learns supplier-specific patterns

• Handles line-item coding, not just totals

• Flags low-confidence invoices for review

• Leaves clean invoices alone

That’s very different from basic OCR.

The goal isn’t to remove humans.
It’s to reduce decision fatigue.

If a system can confidently handle the 70 percent of invoices that follow predictable patterns, bookkeepers can focus on the real exceptions.

The ones that actually need judgment.

The hardest part is that it never “settles”

Traditional businesses eventually stabilize.

Suppliers stay the same.
Processes mature.
Volume grows slowly.

E-commerce rarely settles.

New suppliers appear.
New SKUs launch.
Shipping routes change.
Channels expand.
Tax rules shift.
Platforms update reporting formats.

So the bookkeeping workflow is always evolving.

That’s why e-commerce bookkeeping feels harder year after year, even as tools improve.

The problem is dynamic.

What this means for bookkeepers

If you work with e-commerce clients, the hardest part isn’t learning the rules.

It’s building systems that absorb change.

That means:

• Pricing for complexity, not just volume

• Using tools that handle line-level detail

• Being honest about what automation can and can’t do

• Reducing review time wherever possible

The bookkeepers who thrive here aren’t the ones doing everything manually.

They’re the ones designing workflows that assume messiness from day one.

What this means for e-commerce business owners

If you run an e-commerce business, this explains why bookkeeping often feels expensive or slow.

It’s not inefficiency.
It’s complexity.

Every new channel, supplier, or shipping method adds accounting weight.

The businesses that scale cleanly are the ones that:

• Standardize suppliers where possible

• Separate freight clearly

• Keep purchase orders consistent

• Invest early in smarter AP workflows

Clean inputs save far more money than late cleanups.

The honest takeaway

The hardest part about e-commerce bookkeeping isn’t the math.

It’s managing constant exceptions inside systems that were built for consistency.

Until tools and workflows are designed around that reality, e-commerce bookkeeping will keep feeling harder than it “should” be.

And honestly?

That’s why good e-commerce bookkeepers are worth every dollar.

They’re not just recording history.
They’re holding chaos together quietly, month after month.
