E-Commerce Accounting ERP: When 60,000 Monthly Bookings Break Your System

Practical Recommendations

Marco speaks from experience as a founder.

“We always had €300,000 in dead stock. That was €300,000 in capital tied up — and we were paying interest on it.”

Money that could have been invested in marketing or new pop-up stores.

On execution:

“As a leader, I have to lead by example.”

Today, accounting in his company runs in 90 minutes per month — thanks to consistent automation and clearly defined processes.

The Future: Accounting as a Strategic Tool

A conversation with Alex, CEO of OAZ, shaped Marco’s thinking:

“Most D2C founders who see accounting as a burden haven’t understood the D2C game.”

D2C is a margin game. You must:

• Buy inventory intelligently

• Forecast correctly

• Understand your unit economics

Marco puts it bluntly:

“Accounting is chasing receipts. Receipts create zero value.”

The value emerges when you can identify:

• Where money is leaking

• How to achieve margin uplift

The central message:

E-commerce accounting is too complex to be fully handled by ERP alone.

The combination of:

• Specialized revenue accounting tools

• ERP for inventory and operations

• Standardized interfaces between systems

…allows companies to leverage both worlds optimally.

“Forget the all-in-one dream. Specialized co-existence beats forcing everything into one system.”

FAQs

Why is accounting in e-commerce so complex?

The complexity does not come from individual bookings, but from volume and variability.

€1M monthly revenue at €100 AOV means 10,000 orders. Each order generates multiple accounting entries — revenue, fees, VAT rates, refunds.

On top of that, each sales channel introduces its own tax logic. What is correct in Shopify may be categorically wrong in TikTok Shop.

E-commerce business models turn accounting edge cases into the norm.

Where do breakdowns occur between shop, payment, ERP, and accounting?

Each system holds only part of the truth:

• The shop knows what was ordered

• The payment provider knows what was paid

• The ERP manages inventory

• Accounting must consolidate everything correctly

This leads to discrepancies:

€300,000 revenue in the dashboard, €270,000 in ERP, €190,000 in the bank.

The issue is not faulty systems — but systems built for different purposes.

You notice it at the latest during a tax audit or due diligence.

How does ERP improve financial data quality?

An ERP does not automatically improve data quality. It merely provides structure.

The key question is whether the data flowing into it is correct.

ERP is excellent for inventory management, procurement, and operational processes.

For revenue accounting in e-commerce — especially VAT logic across thousands of cross-channel transactions — ERP is often not granular enough.

Data quality is created before ERP, not inside it.

When does accounting become a growth inhibitor?

Accounting inhibits growth when treated purely as compliance.

If founders don’t know:

• How much capital is tied up in dead stock

• What margins are actually generated

• Where money is leaking

…strategic decisions are made blindly.

Accounting becomes a growth inhibitor when it fails to generate decision-relevant insights — which is almost inevitable with manual processes.

What must be clarified before ERP implementation?

Many companies expect ERP to solve accounting problems.

In reality, it exposes them — or worse, hardens them into a new structure.

Before ERP implementation, you must clarify:

• VAT logic across all channels

• Voucher tax treatment

• Fee structures

• Reconciliation between payment providers and bank accounts

• Whether VAT liability is triggered at delivery or payment

Without these fundamentals, you build a system on unstable ground.
