Phase 1: Laying the Groundwork for a Sound Acquisition
Before a single financial document is scrutinized, you’ll need to carefully lay the foundation for a successful acquisition.
This initial phase is about establishing the rules of engagement, defining the scope of your investigation, and assembling the right expertise.
This phase is all about setting the tone for your entire transaction, and getting it right is crucial!
Why Legal Due Diligence is Non-Negotiable
Legal due diligence is the systematic process of verifying the information presented by the seller and uncovering any hidden liabilities.
It is far more than a box-ticking exercise; it is a crucial step to minimizing risk during an acquisition.
That said, the depth of this due diligence process is often proportional to the size and complexity of the e-commerce business you’ll be acquiring.
For a small, straightforward online store, the process might be pretty simple.
For a multi-million dollar brand with international customers and complex supply chains, it will be an exhaustive undertaking.
Ignoring this step is like trying to drive to a new place without GPS; you’ll probably get lost and waste a lot of time.
The Initial Handshake: LOI and NDA
The legal due diligence process should always begin with two KEY documents:
1. A Non-Disclosure Agreement (NDA): This is a standard prerequisite, ensuring that the sensitive business information you are about to receive remains confidential.
Sellers will almost always require you to sign an NDA before sharing full financial or operational documents.
2. A Letter of Intent (LOI): A letter of intent helps you outline the preliminary terms of the proposed acquisition.
While usually non-binding, the LOI signals serious intent and establishes a framework for price, structure, and an exclusivity period, allowing you to conduct due diligence without the pressure of competing offers.
Assembling Your Acquisition Team
Attempting to navigate an acquisition alone, especially for a first-time buyer, is a high-risk endeavor.
You want to do this with a team of experts to ensure you don’t miss a thing.
Your team should consist of, at a minimum, a lawyer specializing in M&A and an accountant or financial advisor.
These professionals bring the expertise needed to help you interpret complex legal documents, verify financial claims, and identify red flags that an untrained eye would miss.
If you’re a first-time buyer or simply unfamiliar with financial reviews, working with a buy-side broker or advisor can be particularly helpful.

Phase 2: The Core Investigation – A Multi-Faceted Legal Audit
With the groundwork laid, the deep dive begins…
In this phase, you simply move from assumptions to assertions, carefully examining every legal facet of the business.
Each area represents a potential source of value or a hidden liability.
Corporate and Structural Integrity
You must first verify the very existence and good standing of the business as a legal entity.
This involves a thorough review of its foundational documents, including Articles of Incorporation, bylaws, and minutes from director and shareholder meetings.
You need to confirm that the company is legally registered and qualified to operate in all states or countries where it has a physical presence or employees.
Any discrepancies in corporate records or shareholder agreements can complicate or even derail the sale.

Financial Verification (Look Beyond the P&L Statement)
The seller’s profit and loss (P&L) statement is a starting point, not the final word.
A rigorous legal and financial audit involves verifying these numbers against primary sources.
This means cross-referencing claims with transaction logs from platforms like Shopify or Amazon, supplier invoices, and bank statements.
Flippa recommends you to review at least two to three years of financial records, including tax returns and balance sheets, to identify trends and inconsistencies.
Furthermore, requesting statements on an accrual basis gives you a more accurate picture of the business's performance than cash-based accounting.
Intellectual Property (IP) Audit: Protecting the Crown Jewels
When it comes to acquiring an e-commerce business, its brand and digital assets are often its most valuable possessions.
Conducting an intellectual property audit will help you confirm ownership and identify risks associated with the IP the business owns or uses (WIPO).
This audit must verify the clear ownership of trademarks (brand name, logo), copyrights (website content, product photos, descriptions), and the domain name itself.
It's critical to ensure all content is either original or properly licensed to avoid future infringement claims, which can be costly and damaging to the brand's reputation.
Dissecting Contractual Obligations and Liabilities
An e-commerce business operates through a network of contracts. You MUST review each one of them before acquiring the business.
The most common contracts for an e-commerce business include agreements with suppliers, manufacturers, third-party logistics (3PL) providers, and web hosting or software service providers (SLAs).
A crucial question is whether these key contracts will survive a change of control and remain on the same terms.
You must also scrutinize the company’s own public-facing contracts, including its Terms of Service, Privacy Policy, and Return Policy.
This will ensure they are legally compliant and do not expose the business to undue liability.
Phase 3: Navigating the Regulatory Maze – A Compliance Deep Dive
Beyond the company’s internal documents and contracts, you’ll need to consider the vast and ever-changing landscape of government regulation.
Compliance is not optional, and ignorance of the law is no defense.
This phase of ecommerce legal due diligence ensures the business is operating on the right side of the law.
Check The Business Tax Compliance
Tax compliance for online retailers is notoriously complex.
Your due diligence must include a review of federal, state, and local income and sales tax returns for at least the past three years (Source).
A primary focus is sales tax nexus; this is essentially the connection between a seller and a state that requires the business to collect and remit sales tax there.
Nexus can be established through a physical presence (office, warehouse, or employee) or through economic activity that meets certain sales or transaction thresholds.
Unpaid tax liabilities can become your problem post-acquisition, making this a critical area of investigation.
Data Privacy and Security: GDPR, CCPA, and Beyond
How a business collects, stores, and uses customer data is one of the most significant areas of legal risk.
E-commerce businesses must navigate a patchwork of complex data privacy regulations, such as Europe's General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).
Your legal audit must confirm that the business has a compliant privacy policy, obtains proper user consent, and has adequate security measures in place to protect personal data.
Non-compliance can lead to staggering fines and a complete loss of customer trust.
Operational and Employment Liabilities
This is the part where you look at the human element of the business.
You must review all employment and independent contractor agreements to understand the company's obligations to its staff.
It's also essential to assess "key person risk," which is simply the degree to which the business relies on the unique skills or relationships of the current owner.
And lastly, conduct a thorough search for any pending or past lawsuits, regulatory violations, or other hidden liabilities.
This is crucial to helping you avoid inheriting someone else's problems.
Phase 4: Finalizing the Acquisition
After weeks of intensive investigation, the findings from your due diligence process will shape the final stage of the transaction.
This is where you translate the knowledge you’ve gathered into action, negotiating the final terms and legally cementing the transfer of ownership.
The Asset Purchase Agreement (APA): Defining the Deal
The Asset Purchase Agreement (APA) is the definitive legal contract that formalizes the sale.
A complete APA specifies exactly which assets are being acquired (e.g., inventory, domain name, customer lists, social media accounts) and which liabilities, if any, are being assumed.
A well-drafted APA will include representations and warranties from the seller, confirming the accuracy of the information provided during due diligence.
While the APA typically indemnifies the buyer from legacy issues, it is crucial to understand precisely what obligations you are taking on.
Post-Closing: Integration and Transition
The legal process doesn't end the moment the deal is signed.
A critical component of the negotiation is the transition plan. This should be clearly documented and outline the level of training and support the seller will provide post-sale.
A smooth handover is essential to maintain business momentum, retain customers, and ensure that the value you paid for is successfully transferred.
This plan should cover everything from transferring supplier relationships to managing the tech stack.
