What a Supplier Contract Actually Needs to Say

Why an informal footing is genuinely fine to start with

Checked 27 September 2026: most small dropshipping relationships run on an ordinary email thread and consistent, repeated practice rather than a signed formal agreement, and this is a completely normal, workable way for a small relationship to actually operate - not a sign anything is being done wrong. The real question is not whether every relationship needs a formal contract from day one; it is whether the handful of things that actually matter have been discussed and agreed clearly enough, in writing somewhere, that both sides have the same understanding of them.

What pricing terms are actually worth having in writing

How pricing works, and specifically how and when it can change, is worth having clear rather than assumed - whether prices can move without notice, whether any notice period is offered before a change takes effect, and how a price already agreed for a specific order is honoured once it has actually been placed. A supplier's own price-jump behaviour is often exactly the kind of detail that only becomes a real problem in the moment it happens, precisely because it was never discussed in advance. A single line agreeing that price changes come with, say, seven days' notice by email is enough to close most of this gap, without needing anything resembling a formal legal document.

Stock and dispatch commitments, stated plainly

What actually happens when a specific product goes out of stock - whether an order already placed still gets fulfilled, whether a replacement or a refund is offered instead, and what dispatch timeframe is genuinely realistic rather than optimistic - is worth having a clear, shared understanding of before it is tested by a real, live order rather than during one. A stock shortage handled badly downstream very often traces back to exactly this kind of gap never having been discussed upstream.

Who handles a genuinely faulty item

A clear, shared understanding of what happens when an item arrives faulty or damaged - who bears that cost, and how quickly a resolution can be expected - protects both sides from an argument happening for the first time exactly when tempers are already running highest, over a real order a real buyer is waiting on. Agreeing this in the calm of an ordinary week is a genuinely different conversation from negotiating it mid-dispute, and it is worth writing the agreed answer down somewhere both sides can find it again months later, rather than trusting either side's memory of a conversation from early in the relationship.

Why exclusivity clauses are usually worth resisting

A supplier occasionally offers, or asks for, some form of exclusivity or non-compete arrangement, and for a small reseller this is usually worth resisting rather than accepting readily - it trades away real flexibility, the same flexibility already worth protecting when starting with just one supplier, in exchange for terms that rarely benefit a small account as much as they benefit the supplier offering them. This is not a blanket rule against every such arrangement, but a reason to weigh one specifically and carefully rather than accept it as a routine part of doing business.

Minimum order quantities and how they quietly reshape a relationship

A supplier introducing a minimum order quantity, or raising an existing one, partway through a relationship is a genuinely common way an informal arrangement can shift underneath a seller without ever being explicitly renegotiated - a supplier who was happy to fulfil single-unit dropship orders when the relationship began sometimes moves, as their own business grows, toward wanting batch orders instead, which can be entirely incompatible with how a dropshipping model actually works. Asking plainly, early in a relationship, whether single-unit dropship fulfilment is the supplier's genuine, ongoing offering, or a temporary accommodation while the supplier's own volume is still small, is worth doing directly rather than discovering the answer only once a minimum order requirement is introduced without warning on a product line a shop already depends on.

What happens if a supplier's own photos turn out not to be theirs to use

Beyond simply confirming a supplier is happy for their photos to be used, it is worth thinking through, if only briefly, what happens if those photos later turn out to have been used by the supplier themselves without proper rights - lifted from a manufacturer's own marketing materials without a genuine licence, for instance. A seller who has built listings around images a supplier did not actually have the right to distribute can still face a copyright complaint themselves, since eBay's own reporting tools do not generally investigate the original source of an infringing image before acting on a report - they act on the listing actually carrying it. This is a low-probability but genuinely costly risk worth at least briefly raising with a supplier directly - simply asking where their own product photography originates and confirming it is genuinely theirs to license onward - rather than assumed safe purely because the supplier has offered the images freely and without any conditions attached.

How either side can actually end the relationship

A clear, mutual understanding of how the relationship itself can be ended - by either side, with what notice, and what happens to any orders already in progress at that point - is worth having before it is ever needed, precisely because it is the term most likely to matter exactly when a relationship has already gone wrong enough that trust and goodwill can no longer be relied on to sort it out amicably. A short, plainly worded line - either side can end this with, say, 30 days' written notice, with existing orders honoured - closes off a surprisingly large amount of later argument for very little effort now.

A specific legal point most sellers never think to include: what happens to a buyer's data

Every dropshipped order involves handing a supplier a real buyer's name and delivery address so the item can actually be sent out - which means, in UK data protection terms, personal data is being passed from the seller to the supplier for a specific purpose. The Information Commissioner's Office is direct on the underlying rule: its own guidance on contracts between controllers and processors states plainly that whenever a controller uses a processor to handle personal data on their behalf, there must be a written contract or other legal act in place setting out the processing involved and the processor's obligations around it. Exactly how a specific seller-supplier relationship is classified under this rule depends on the details of that relationship and is worth checking properly rather than assumed either way, but the underlying point is worth taking seriously regardless of the precise classification: buyer names and addresses are being shared with a third party as a routine part of every single order, and a genuinely careful supplier relationship has at least discussed, even informally, how that data is handled, stored, and eventually deleted once an order is fulfilled - a detail worth adding to the same short confirming email covering pricing, dispatch, and faults, rather than left as something neither side has ever actually raised.

Payment terms, the part sellers agree to without thinking

Most small dropshipping relationships pay a supplier upfront, per order, which sidesteps a large part of what payment terms usually need to cover - but it is still worth being clear about exactly when payment is taken, what currency and method are used, and what happens if a payment fails or is delayed on a specific order. The Small Business Commissioner's own contract guidance singles payment terms out as one of the most important parts of any business-to-business contract, especially for small and micro businesses, precisely because a late or disputed payment can cause real cash-flow strain out of proportion to the sum involved. Where a relationship does extend any form of credit - stock supplied before payment, or a running account settled periodically rather than order by order - agreeing the payment window plainly in writing, and what happens if it is missed, is worth doing before the arrangement starts rather than after the first missed payment has already strained the relationship.

The statutory right that exists even without a contract mentioning it

It is worth knowing that UK law gives a business a right to claim interest and debt recovery costs on a genuinely late commercial payment, whether or not a contract says anything about it at all. The government's own guidance on late commercial payments confirms that if no payment date has been agreed, the law treats a payment as late 30 days after whichever is later of the invoice being received or the goods actually being delivered - and that any agreed payment period longer than 60 days for an ordinary business transaction has to be genuinely fair to both sides. This cuts both ways in a supplier relationship: it is a real, statutory backstop protecting a seller if a supplier ever owes them money back - a refund on a faulty batch, an overcharge, a credit note never actually issued - and fails to pay it within a reasonable time, and it is equally a real obligation resting on the seller's own side if payment terms have ever been extended to them by a supplier. Few small dropshipping relationships ever need to invoke this formally, since most run on immediate, order-by-order payment, but knowing it exists is worth more than nothing the one time a genuine payment dispute does arise and drags on past a reasonable point.

Who actually helps if a genuine payment dispute won't resolve informally

Beyond the statutory right to interest, the Small Business Commissioner's own service is worth knowing about specifically for this scenario: a small business (fewer than 50 staff) owed money by a larger one can ask the Office of the Small Business Commissioner to contact the other side directly, help resolve the dispute without going to court, and advise on the seller's own rights - entirely free. In a typical dropshipping relationship the seller is usually the one paying the supplier, not the one owed money, so this service applies most directly to the specific, narrower situation where a supplier itself owes the seller money back and is not paying it - a promised refund on damaged stock, for instance - rather than to the relationship generally. It is still worth knowing this exists before assuming the only options for a genuine unpaid debt are chasing informally forever or an expensive court claim; there is a free, practical middle step most small sellers never think to use.

Who actually owns the right to use a supplier's product photos and descriptions

A dropshipper listing a supplier's product almost always uses that supplier's own photos and, often, a close variation of their own product description - and it is worth being clear, even informally, that the supplier is genuinely happy for those images and text to be used this way, rather than simply assumed because the supplier has never objected. Most suppliers actively want their photos used, since it is exactly what helps the product sell, but a small number restrict this, particularly with suppliers who also sell direct to the public and are protective of a specific brand image, or where the photos themselves were licensed from a separate photographer or agency and the supplier does not actually hold the right to sub-license them further. A short, direct question - are we free to use your product photos and descriptions in our own listings - settled once at the start of a relationship, avoids a genuinely awkward situation later if a supplier ever raises it as a problem after listings have already been built around their content.

What it doesn't need to be, according to the UK's own guidance

The UK government's own Small Business Commissioner contract guide is aimed at exactly this kind of relationship - a business supplying goods or services to another business - and its own advice is refreshingly plain: a contract does not have to be long or complicated, but it should be clear, specific, and reflect how both sides actually intend to work together. Its list of what a contract should cover at minimum lines up closely with what is set out here - what is being supplied, how much, how long the arrangement runs, how it ends, and who is actually involved - and its central point is one worth repeating directly: an ordinary written record that both sides can point back to later is legally enforceable in a way a remembered conversation is not, and that gap matters most exactly when a dispute has already started and each side's memory of what was agreed no longer matches the other's.

A practical way to actually do this without overengineering it

None of the above needs a solicitor-drafted document to be worth having for an ordinary small supplier relationship. A short email, sent after an initial conversation, summarising what has been agreed on each of the points above and asking the supplier to confirm it is a genuinely fair reflection, creates exactly the kind of simple written record the Small Business Commissioner's own guidance points to - not a formal contract in the strict legal sense, but a real, dated record either side can refer back to if a disagreement later arises about what was actually agreed. This is worth doing early in a relationship, while everything is still fresh and uncontested, rather than retrofitted after a dispute has already made the two sides' memories start to diverge.

Why this is a starting checklist, not the whole answer

Everything above is general, practical information worth having a shared, clear understanding of - it is not legal advice for a specific relationship, and a significant supplier arrangement, particularly one involving real ongoing volume or a formal written contract a supplier has drafted, is worth a real conversation with a solicitor rather than treated as fully covered by a checklist like this one.

The extra questions worth asking when a supplier is based overseas

A supplier based outside the UK adds a specific extra question worth settling clearly: who is actually responsible for import duty, VAT at the border, and customs clearance on a shipment coming into the UK, and is that cost already included in the price being quoted or added on top of it later. International commercial terms - commonly shortened to Incoterms, such as "Delivered Duty Paid," where the supplier has already handled and included import costs, versus "Delivered At Place," where those costs land on the buyer separately - describe exactly this split, and it is worth asking a specific overseas supplier plainly which basis they are quoting on, rather than assuming, since the two can produce a meaningfully different landed cost for the same headline price. A surprise customs charge arriving on an order already dispatched to a buyer is a genuinely awkward, costly problem to discover for the first time mid-relationship rather than asked about plainly before the first order is placed.

What to do if a supplier won't confirm anything in writing

A supplier who declines to confirm even a short summary email, or who goes quiet when asked to, is itself a useful signal worth taking seriously rather than brushing off as awkwardness or a busy inbox. It does not automatically mean the relationship is a bad one - some suppliers are simply informal by habit and slow to reply to anything that isn't a direct order - but it is worth a second, more direct ask before assuming the first email was just missed. A supplier who actively avoids confirming basic terms, repeatedly and across more than one attempt, is telling a seller something worth listening to about how disputes with that supplier are likely to go later, when the stakes are higher than a routine confirmation email.

In that situation, keeping a seller's own dated record of what was discussed and agreed - even unconfirmed by the other side - is still worth doing. It carries less weight than a mutually confirmed record, but it is still far better than nothing at all if a disagreement does arise later, and it gives an honest paper trail of what a seller reasonably understood to have been agreed, and when.

A worked example

A supplier relationship built on a single confirming email early on - pricing notice, dispatch expectations, and who covers a faulty item, all agreed and summarised in writing - holds up cleanly months later when a specific order arrives damaged, because both sides can simply point back to what was already settled rather than arguing about it fresh. The same relationship with nothing ever written down, tested by the exact same damaged order, becomes a genuinely harder conversation, not because either side is acting in bad faith, but because there is no shared record to settle what was actually agreed in the first place.

Where Sellhelm actually fits

Sellhelm's own Suppliers page keeps a supplier's own page and policies linked directly from every product sourced from them, useful for checking what has actually been agreed or published - though the underlying agreement itself, formal or informal, stays a conversation to have directly with each specific supplier.
