The master services agreement (MSA) is the framework contract for a recurring services relationship between two B2B counterparties. It carries the terms that apply across the relationship — fees and invoicing, IP, confidentiality, warranties, indemnities, limitation of liability, termination — and is then operationalised through one or more statements of work (SOWs) that specify scope, deliverables, schedule, and price for each engagement. The MSA/SOW pattern allows commercial parties to onboard a counterparty once and execute many subsequent engagements without renegotiating the framework. This page is the English-law drafting reference; the SOW companion sits at Statement of Work, and the boilerplate flow-through points to standard clauses and unfair contract terms.

MSA + SOW framework

The architecture has three layers:

  1. MSA — framework terms applicable to all services.
  2. SOW — engagement-specific terms (scope, deliverables, schedule, fees).
  3. Change Order — formal mechanism for amending an in-flight SOW.

The MSA opens with a recital that future SOWs will be agreed by signed instruments referencing the MSA, and that each signed SOW is incorporated into and forms part of the MSA. The legal device is that each SOW is a discrete contract for the specified work, governed by the MSA’s terms; some drafters take the converse approach (the MSA is the single contract, and SOWs are simply work orders), but the practical drafting is similar.

Order of precedence

The order-of-precedence clause resolves conflict between the MSA and a SOW (or other transaction document). Three drafting patterns are common:

The third pattern is the most common in sophisticated drafting. The drafter should be explicit: an unclear precedence clause is itself a source of dispute.

Implied terms — SGSA 1982

The Supply of Goods and Services Act 1982 implies three terms into B2B service contracts:

These terms can be excluded or restricted in B2B contracts subject to the reasonableness test under UCTA 1977 — see unfair contract terms. A blanket exclusion of all SGSA-implied terms is unlikely to satisfy the reasonableness test in a standard-terms supplier contract; well-drafted MSAs replace the implied terms with express warranties of equivalent or greater specificity.

Services vs. deliverables; acceptance

A core distinction is between services (the supplier’s activities) and deliverables (the artefacts produced). The contract structure typically:

A typical acceptance regime: deliverable submitted; customer has 15 business days to test; customer either accepts or notifies of failure with specifics; supplier has 15 business days to cure; if not cured within a further period (or after a defined number of cure cycles), customer may either accept with credit, reject and terminate the SOW, or refer to dispute resolution. Deemed acceptance applies if no notice within the test period.

Fees, expenses, and invoicing

Fee structures: fixed-price, time-and-materials (with or without cap), milestone-based, success-based, retainer. The MSA should specify:

Late payment interest

The Late Payment of Commercial Debts (Interest) Act 1998 implies a statutory right to interest on commercial debts paid late. The current rate (as amended by SI 2013/395 implementing Dir. 2011/7/EU) is Bank of England base rate plus 8 percentage points, plus a fixed-sum debt-recovery cost (between £40 and £100 depending on debt size). The right may be displaced by express contract only where the substituted remedy is “substantial” — courts have struck down contractual interest rates materially below the statutory rate as inadequate.

Late Payment Interest. Without prejudice to the Supplier’s rights under the Late Payment of Commercial Debts (Interest) Act 1998, any undisputed sum not paid by the due date shall bear interest from the due date until paid at the rate of 4% per annum above the Bank of England base rate from time to time.

Drafters who exclude statutory interest with a lower contractual rate should ensure the alternative is “substantial” within the 1998 Act and pay attention to the Yuanda (UK) Co Ltd v WW Gear Construction Ltd [2010] EWHC 720 (TCC) line.

Intellectual property — CDPA 1988

The IP allocation clause is one of the most negotiated provisions of any MSA. The starting point is the Copyright, Designs and Patents Act 1988 (CDPA 1988):

The critical point for the MSA drafter is that under CDPA 1988 the commissioner of a work does not automatically own its copyright. This is a material change from the pre-1988 position. Where a supplier delivers bespoke software, reports, or designs to a customer, the supplier’s employees (or the supplier itself, where created by individual contractors via CDPA s.11(2) employment-route) own the copyright unless and until an express written assignment is executed. Robin Ray v Classic FM plc [1998] FSR 622 (Lightman J) confirmed that, in the absence of express assignment, the most a commissioner of bespoke material acquires is an implied licence to use the material for the contemplated purpose; the implied licence is narrow and does not authorise sub-licensing or further commercial exploitation.

The drafting choice is between three positions:

Pre-existing background IP is carved out under any of the three approaches: the party that brought the background IP retains it, and grants the counterparty whatever licence is needed to use the deliverables.

IP Assignment (Customer-Favouring Position). With effect from the date of payment in full for the relevant Services and Deliverables, the Supplier assigns to the Customer with full title guarantee all intellectual property rights (including copyright, database rights, design rights, and patents) in and to the Deliverables (excluding any Supplier Background IP incorporated therein). The Supplier shall, at the Customer’s reasonable request and cost, execute such further documents as are necessary to perfect such assignment.

The full-title-guarantee covenant (under LPMPA 1994) gives the assignee statutory protection against undisclosed encumbrances. Background IP is licensed by a separate sub-clause:

Background IP Licence. The Supplier grants to the Customer a non-exclusive, perpetual, irrevocable, worldwide, royalty-free, sublicensable licence to use any Supplier Background IP incorporated in the Deliverables solely as part of and to the extent necessary for the Customer’s exercise of its rights in the Deliverables.

Patent rights are addressed under the Patents Act 1977; assignment of registered trade marks under Trade Marks Act 1994 s.24; database rights under the Copyright and Rights in Databases Regulations 1997 SI 1997/3032.

Confidentiality

The MSA confidentiality clause is usually a self-contained clause covering both parties’ confidential information, with a cross-reference to any NDA executed earlier. The clause should: (a) define Confidential Information; (b) impose non-disclosure and non-use obligations; (c) carve out the standard exclusions; (d) specify survival (3-5 years for ordinary; indefinite for trade secrets); (e) include a PIDA whistleblower carve-out where individuals are bound; (f) provide for return/destruction at termination. See NDA for fuller treatment.

Warranties — express and implied

Express warranties typically include:

SGSA s.13 (reasonable care and skill) is the floor and cannot be excluded by an unreasonable term in standard B2B contracts (UCTA s.3). The express warranties usually go beyond this floor.

IP infringement indemnity

The IP infringement indemnity is the most negotiated single provision in many MSAs. Its function is to allocate the risk that the supplier’s deliverables infringe third-party IP rights. The supplier’s position is to limit the indemnity (scope, time, cap, exceptions); the customer’s position is to make it broad and uncapped.

Standard structure:

The indemnity is typically a carve-out from the limitation of liability cap — supplier wants the indemnity capped, customer wants it uncapped or capped at a higher level than the general cap.

Limitation of liability

The limitation-of-liability clause carries economic significance disproportionate to its length. The structure follows the standard-clauses architecture, with the principal MSA-specific decisions being:

The Supreme Court emphasised in Triple Point Technology Inc v PTT Public Co Ltd [2021] UKSC 29 that liability caps are construed by reference to the natural meaning of the words used and that recent commercial-court authority favours upholding negotiated cap mechanisms in sophisticated B2B contracts.

Consequential loss

The English meaning of “consequential” is narrower than commercial parties often suppose. Hotel Services Ltd v Hilton International Hotels (UK) Ltd [2000] 1 All ER (Comm) 750 confirms that “consequential” in an exclusion clause refers to losses falling within the second limb of Hadley v Baxendale — losses not arising naturally from the breach but only by reason of special circumstances communicated at contract formation. Star Polaris LLC v HHIC-Phil Inc [2016] EWHC 2941 (Comm) reinforces that drafters should list categories explicitly to exclude first-limb losses (loss of profit, loss of revenue). A clause that excludes only “consequential loss” leaves substantial categories of recoverable loss unprotected.

Insurance

A B2B MSA typically requires the supplier to maintain insurance, including:

The supplier is required to maintain cover throughout the term and for a tail period (typically 6 years from termination, mirroring the simple-contract limitation period under Limitation Act 1980 s.5).

Termination

The termination clause provides for both convenience and cause termination. The principal cause grounds are:

Notice and cure-period provisions are conventional: cure period typically 30 days for non-payment, 60 days for other material breach; immediate termination right for insolvency and serious breaches (e.g. data-breach causing irreparable harm).

Post-termination consequences should be addressed: outstanding payments, return/destruction of materials, transition assistance (for which separate fees may be payable), continuing IP licences (perpetual customer licence to use deliverables typically survives), and surviving clauses (confidentiality, IP, indemnities, governing law, limitation of liability).
