Co-founder Agreements for UK Product Import Businesses

If you and a co-founder are building a product import business, a handshake and a shared spreadsheet are not enough. Import businesses create pressure points early: one founder may source suppliers overseas, another may fund stock, one may handle customs and labelling, and both may assume they own the same customer relationships. Common mistakes include splitting shares equally without matching the real workload, leaving decision-making unclear when a shipment is delayed or non-compliant, and failing to say what happens if one founder stops contributing after the first purchase order.

A well-drafted co-founder agreement for product importer businesses sets rules before those problems become expensive. It should deal with ownership, roles, decision-making, deadlock, founder exits, IP, confidentiality, and what happens when one founder signs supplier terms or takes on stock risk without approval. This guide explains what a co-founder agreement means in a UK product import context, the legal issues to check before you sign, and the mistakes that repeatedly trip up import founders before they pitch stockists, launch an online store, or commit to a large manufacturing run.

Overview

A co-founder agreement is the rulebook between the people building the business together. For a UK product importer, it should do more than record share splits, it should allocate authority over sourcing, stock commitments, product compliance, finance, customer channels and exits.

The strongest agreements deal with the founder moments that create real commercial risk, especially before you sign supplier contracts, before you spend money on setup, and before you accept the provider's standard terms.

• Record who owns what, including shares, cash contributions, stock, brand assets and supplier relationships.
• Set each founder's role, authority limits and approval rules for orders, exclusivity, debt and guarantees.
• Deal with vesting or leaver rules if one founder leaves early or stops contributing.
• Cover intellectual property, confidentiality and ownership of product specifications, packaging and branding.
• Include deadlock procedures, dispute steps and practical exit options.
• Align the agreement with the company's articles, shareholder arrangements and any director duties.
• Address import-specific risks such as product safety responsibility, recalls, labelling and non-compliant stock.

What Co-founder Agreement for Product Importer Means For UK Businesses

For a UK importer, a co-founder agreement should answer who is responsible for what, who can commit the business, and who carries the risk when a product or supplier causes problems.

That sounds simple, but product import businesses often have uneven founder contributions. One person may bring cash. Another may bring supplier contacts in China, Turkey or the EU. Another may have built the brand, the packaging design and the sales channels. If none of that is written down properly, disagreements usually appear once the first container is delayed, defective or unsellable.

It is not just about a share split

Many founders think the agreement only needs to say "we are 50/50" or "we are 60/40". In practice, that is only one part of it. The document should explain why the split exists and what each person is expected to do in return.

For example, if one founder is putting in £40,000 for initial stock and the other is handling sourcing, quality checks and compliance paperwork, the agreement should say whether those contributions are treated as:

• share capital,
• a director's loan,
• sweat equity,
• a mix of cash and services, or
• future milestones that trigger more equity.

This matters later if the business needs more money, if one founder leaves, or if the company sells.

Import businesses have operational pressure points

A normal founder dispute can damage any startup. In an import business, the damage often lands faster because stock is purchased upfront and mistakes are hard to reverse. Goods may already be in production or on the water before founders realise they never agreed on who had authority to place the order.

Your agreement should be drafted with practical decisions in mind, such as:

• who approves a new supplier,
• who can agree minimum order quantities,
• who signs freight, warehousing or fulfilment contracts,
• who checks product safety and labelling rules,
• who manages customer claims and refunds,
• who decides whether defective stock is reworked, discounted or destroyed.

It should fit the company structure

If you trade through a UK limited company, the co-founder agreement needs to fit with the company's constitutional documents and ownership structure. Founders are often also shareholders and directors, but those roles are not identical.

A shareholder owns part of the company. A director manages the company and owes legal duties to it. Your co-founder agreement should not say one thing while the articles of association or shareholder arrangements, such as a shareholders' agreement, say another. If the documents conflict, you can end up with a messy argument about who actually had authority.

It should protect assets that are easy to overlook

Import businesses often build value through intangible assets well before profits arrive. A founder may negotiate exclusivity with a manufacturer, create private label packaging, prepare compliance files, or build relationships with stockists and distributors.

Your agreement should say clearly that business assets belong to the company, not to the individual founder who created or sourced them. That can include:

• brand names and logos,
• product specifications and customisations,
• packaging designs and artwork,
• supplier lists and negotiated terms,
• customer lists and wholesale contacts,
• marketing content, photography and ad accounts.

If that ownership is left vague, a departing founder may argue that they can take a supplier or the brand concept with them.

Legal Issues To Check Before You Sign

Before you sign a co-founder agreement for a product importer, make sure it deals with authority, money, ownership and compliance in a way that matches how the business will actually operate.

This is where founders often get caught. The document looks balanced on day one, but it has not been tested against real commercial decisions.

Roles and decision-making authority

Spell out each founder's role in plain English. Avoid vague labels such as "operations" or "sales" if they hide important authority questions.

For an import business, specify who can decide:

• which suppliers to use,
• whether the company enters exclusive supply arrangements,
• order values above a set threshold,
• whether product changes can be approved,
• whether payment terms can be agreed,
• whether the company can appoint agents, distributors or marketplaces.

You should also say which decisions require both founders, board approval or shareholder approval. That helps avoid one founder committing the business before the other has reviewed the risk.

Cash contributions, loans and future funding

Import businesses usually need upfront capital for stock, freight, duties, storage, sampling and returns. The agreement should say exactly what each founder is contributing and what happens if more money is needed.

Include clear rules on:

• initial cash invested,
• whether funds are equity or loans,
• whether founders must contribute further capital,
• what happens if one founder cannot or will not contribute,
• whether external investment can dilute the founders.

Without this, one founder can feel forced into putting in more money just to save existing stock from being stranded.

Shares, vesting and leaver provisions

Founders should not always earn all of their equity on day one. A vesting mechanism or carefully drafted good leaver and bad leaver terms can be very useful where the business depends on ongoing contribution.

This is especially relevant if one founder is expected to spend months sourcing manufacturers, handling packaging changes and managing product compliance. If that founder leaves after the first order, the remaining founder may be left doing the work while still sharing ownership equally.

Leaver clauses should cover:

• when a founder is treated as having left,
• whether the company or other founders can buy their shares,
• how the price is set,
• whether misconduct changes the valuation,
• what happens to unvested equity.

Intellectual property and confidential information

The agreement should say that IP created for the business is assigned to the company, not kept personally by the founder who produced it.

That matters if a founder designs packaging, commissions a logo, writes product descriptions, creates a product specification, or negotiates a custom mould or manufacturing process. It is also worth covering confidential information, including supplier pricing, margin data, customer contacts and product development plans, and considering trade mark protection for key brand assets.

Import compliance responsibility

A co-founder agreement cannot replace product compliance advice, but it can allocate internal responsibility. Someone still needs to make sure products meet applicable UK requirements, including labelling, safety and technical documentation where relevant.

Depending on the products, that may involve checking:

• product safety standards,
• labelling and packaging rules,
• instructions and warnings,
• who is named as importer, manufacturer or distributor,
• record-keeping and traceability,
• how recalls or complaints are handled.

If the founders do not assign responsibility, both may assume the other person is dealing with it. That is a dangerous gap before you print labels or place a repeat order.

Restrictions on competition and poaching

Founders often want some protection if a co-founder leaves and tries to take the supplier, the customer list or the brand concept. Restrictions can help, but they need to be drafted carefully and reasonably to be more likely to hold up.

The agreement may include limits on:

• competing with the business for a period after leaving,
• soliciting customers, stockists or distributors,
• poaching staff or contractors,
• using confidential supplier information.

The main goal is to protect legitimate business interests without overreaching.

Deadlock and dispute procedures

If you have two founders with equal power, you need a process for when they disagree. Deadlock clauses are not just for dramatic disputes. They matter when one founder wants to place a major order and the other wants to pause because quality checks are incomplete.

A sensible clause can set out:

• which decisions count as deadlock matters,
• a meeting and escalation process,
• timeframes for resolution,
• whether mediation is required,
• whether one founder can buy out the other in certain cases.

Common Mistakes With Co-founder Agreement for Product Importer

The most common mistake is treating the agreement as a generic founder template instead of tailoring it to the stock, supplier and compliance risks of an import business.

Here are the issues that come up again and again.

Equal shares, unequal contribution

Founders often default to a 50/50 split because it feels fair at the start. The problem appears later when one founder is handling supplier disputes at midnight, checking samples, fixing labelling, and funding emergency air freight, while the other contributes far less than expected.

That does not mean equal ownership is always wrong. It means the expectations behind it need to be written down.

No approval threshold for stock commitments

One of the biggest risks in product importing is overcommitting on stock. If your agreement does not require joint approval above certain order values or contract terms, one founder may lock the business into minimum order quantities, exclusivity or long payment obligations too early.

This often happens before you sign a contract with a manufacturer or freight partner using standard terms that were never properly reviewed in a contract review.

Ignoring who owns supplier relationships

Founders sometimes assume the company automatically owns a supplier connection because the business paid for samples or placed orders. That is not always enough to stop a departing founder from trying to continue the relationship personally.

Your agreement should make it clear that supplier negotiations and business opportunities developed for the venture belong to the company.

Leaving compliance in the background

Import founders can get very focused on price, lead times and margin. Then a shipment arrives with packaging problems, missing warnings or issues about who is identified as the importer.

A founder agreement will not solve the regulatory issue itself, but it should say who is responsible internally for checking compliance, retaining records and managing any corrective action.

No clear exit if trust breaks down

A co-founder relationship can become unworkable long before anyone wants a legal fight. If the agreement has no practical exit route, the business can stall while stock sits in storage and customer orders keep coming in.

Good exit drafting should deal with valuation, timing, share transfer mechanics and restrictions after departure. Without that, founders are left arguing from scratch when relations are already strained.

Forgetting director duties

If both founders are directors, they must act in the company's interests, not only their personal interests as founders or shareholders. This matters when one founder wants to approve a deal that benefits a related party, a family contact, or another business they are involved in.

Your internal agreement should sit alongside those legal duties and include rules on conflicts, disclosure and approvals.

Copying a document that does not fit the business

Generic templates often miss the issues that matter most for import businesses. They may say nothing useful about stock losses, product recalls, tooling ownership, failed inspections, insurance obligations or authority to sign overseas supplier terms.

This is why founders should test the agreement against real scenarios. Ask what happens if:

• a shipment fails quality inspection,
• goods need relabelling after arrival,
• the supplier insists on a personal guarantee,
• one founder wants to change factories,
• a marketplace suspends listings after a safety complaint,
• one founder disappears during peak trading.

If the document does not answer those points clearly enough, it needs more work before you sign.

FAQs

Do two founders of a UK importing business really need a written co-founder agreement?

Yes. It is one of the clearest ways to avoid disputes about ownership, roles, funding and exits. Import businesses take on stock and supplier risk early, so assumptions become expensive quickly.

Is a co-founder agreement the same as a shareholders' agreement?

Not always. They often overlap, and some businesses combine the issues into one document. What matters is that the founders' arrangements match the company's share structure, articles and director roles.

Should the agreement cover product compliance responsibilities?

Yes, at least at an internal responsibility level. It should say who handles checks, records, complaints and recall decisions, even though separate compliance advice may still be needed for the products themselves.

What if one founder brings supplier contacts instead of cash?

The agreement should record that contribution clearly and explain how it affects equity, decision-making and ownership of those business relationships. Do not leave it as an informal understanding.

Can we just sign a simple template and update it later?

You can, but that often creates trouble if orders are placed or money is spent before the update happens. It is better to settle the key points before you sign supplier contracts or commit to major stock purchases.
