How to Build Price Adjustment Mechanisms into Sri Lanka Leases and Supplier Contracts During Inflation Volatility

Office leases, procurement agreements and outsourcing contracts should not rely solely on a fixed price, nor should they accept broad wording such as “prices may increase if costs rise”. A more practical approach is to document adjustable costs, review points, calculation methods, notice procedures and dispute arrangements separately, with input from the business, finance and appointed professional advisers.

Inflation, exchange-rate movements, import costs and labour costs may affect the cost of performing local contracts in Sri Lanka in different ways. Foreign businesses should particularly avoid two extremes: refusing any adjustment mechanism solely to lock in a budget, which may lead suppliers to seek renegotiation during performance; or accepting a price adjustment right that is too broad, uncapped or unsupported by documentary evidence.

Start by separating costs that may be adjusted

A price adjustment mechanism should not automatically apply to the full contract amount. Before signing, break the quotation down into relatively fixed elements and potentially variable elements.

Contract type	Items that commonly require separate consideration	Questions to clarify
Office lease	Rent, building management charges, parking, common-area charges, utilities	Which charges are included, and which are payable separately by the tenant? Is written notice required before charges are adjusted?
Procurement contract	Product unit price, transport, packaging, import-related costs, storage, delivery-related services	Which cost item is linked to the unit-price change? Must the supplier provide procurement or transport evidence?
Outsourcing contract	Staff wages, site management, equipment, consumables, transport, overtime or additional services	What is included in the base service scope? Will changes in headcount or service hours be charged separately?

For office leases, businesses should not treat “rent” as the only cost. Building management charges, utilities, maintenance, reinstatement works, parking, security and other building services should be reviewed separately. In procurement and outsourcing contracts, suppliers should also be asked to distinguish between the base price and variable items, rather than grouping all changes under a general reference to “market conditions”.

A price adjustment clause should answer at least five questions

1. What events trigger a review?

The trigger should be specific, observable and connected to the contract’s cost structure. For example, the parties may agree to review pricing at fixed intervals, at renewal, following a change in service scope, or when a material cost change confirmed by both parties occurs.

A “price review” should not mean that a supplier may increase prices unilaterally. The contract should distinguish between the event that triggers a review, the party entitled to request an adjustment, the period for negotiation, and how performance or unfinished services will be handled if no agreement is reached.

2. Which items may be adjusted?

Adjustable and non-adjustable items should be listed in the contract schedule or quotation. For example, an outsourcing provider may be permitted to submit a revised quotation for additional personnel, extra shifts or additional on-site services requested by the client. That should not automatically change all management fees for the existing agreed service scope.

If a supplier requests an adjustment because of exchange-rate movements, the business should ask further questions: in which currency does the supplier actually procure goods or services, which costs are genuinely affected by the exchange rate, and whether an exchange-rate buffer was already included in the original quotation? Pricing currency and payment arrangements for Sri Lanka projects can also be considered alongside the published article, “Pricing Sri Lanka Projects: Local Currency, US Dollars or Dual Currency? Separate Quotation, Invoicing and Collection First”.

3. How will the adjustment be calculated and evidenced?

Contracts should avoid wording such as “adjusted to market price” or “adjusted for inflation” without further detail. A more workable approach is to require the party requesting an adjustment to explain:

• the specific cost item affected;
• the unit price, quantity or service scope before and after the proposed adjustment;
• the calculation period and proposed effective date;
• quotations, invoices, payroll records, procurement records or other written evidence supporting the adjustment; and
• whether alternatives are available, such as substituting materials, reducing service scope or changing delivery frequency.

A business does not necessarily need to specify a particular index, percentage or fixed cap in every contract. Before signing, however, the finance team should confirm whether the proposed calculation basis is available, suitable for internal audit and consistent with headquarters budgeting practices. Wording relating to indices, currency conversion or tax treatment should be reviewed by appointed legal, tax or finance professionals in light of the nature of the contract.

4. How much notice is required, and when does an adjustment take effect?

The notice process should align with procurement, payment and internal approval cycles. A business may require the supplier to submit a written request together with supporting documents. Prices that have not been confirmed by both parties through the agreed process should not simply appear on an invoice.

For ongoing services, the contract should clearly state whether an adjustment takes effect in the next billing cycle, upon renewal, or only for additional services. For one-off purchases, the parties should clarify the quotation validity period, whether pricing may still change after an order is confirmed, and who bears the risk of additional costs if delivery is delayed.

5. What happens if the parties cannot agree?

The purpose of a price adjustment mechanism is not limited to whether a price may increase. It should also address exit and transition arrangements if the parties cannot agree. Businesses should consider whether the existing service may continue until a handover point, whether the service scope can be reduced, whether an alternative supplier may be introduced, and how records, equipment, deposits and unfinished work will be handed over.

This section should be consistent with the contract’s notice, default, termination and dispute-resolution provisions. If the contract value is significant, the service is ongoing, or the supplier performs a critical operational function, the contract should be reviewed by a properly qualified professional organisation. For the structure of dispute-resolution clauses, see the published article, “How to Design Dispute Resolution Clauses When Contracting with Sri Lanka Customers or Suppliers”.

Use different review methods for different contract types

Office leases: separate rent from building-related charges

In office agreements, businesses should check whether rent adjustments are being mixed with management charges, utility charges and maintenance responsibilities. In addition to pricing, the agreement should address how bills are provided, the basis of measurement, treatment of unpaid amounts, the permitted use of the security deposit and the conditions for its return.

If the lease includes fit-out works, furniture, internet, cleaning or security services, confirm whether these are provided at a fixed package price, charged based on actual use, or subject to repricing at renewal or following a change in service scope. Do not rely only on verbal explanations from sales personnel; key arrangements should be included in the formal contract or in an attachment confirmed by both parties.

Procurement contracts: manage price, quantity and delivery terms together

Pricing risk in procurement contracts often arises from inaccurate volume forecasts, changes in delivery batches or specification changes, rather than inflation alone. Minimum purchase quantities, replenishment arrangements, substitute products, quality acceptance, delivery delays and return arrangements should be reviewed together with the price adjustment mechanism.

If a supplier cites changes in raw-material, transport or import costs, the business may ask whether the impact relates to existing orders or future orders. Confirmed orders, unconfirmed orders and future orders under a framework agreement will usually require separate rules on which price applies.

Outsourcing contracts: prevent “staff cost changes” from becoming an unlimited adjustment basis

Security, cleaning, customer service, administrative support, delivery and other outsourced services often involve headcount, shift arrangements, overtime, replacement staff and on-site management. The statement of work should identify positions, work locations, shifts, service hours, replacement arrangements and reporting requirements before the parties discuss which staffing changes may trigger a revised quotation.

Where an outsourcing provider is responsible for employee-related administration or payment obligations, the business should also require relevant records to be provided as agreed and have responsibility boundaries reviewed by appointed professional advisers. A price adjustment clause should not be treated as a substitute for contractual arrangements concerning labour, tax or payment obligations.

Maintain a documented contract review register

After signing, a local responsible person or project coordinator should maintain a simple register recording contract versions, quotation schedules, adjustable items, review dates, submitted price adjustment requests, supporting documents, internal approvals and written confirmations from both parties. The purpose is not to add unnecessary process, but to prevent the finance team, on-site procurement team and headquarters budget owners from relying on different versions of pricing.

For projects involving multiple suppliers, businesses may use a standard price adjustment request form requiring suppliers to state the reason for the adjustment, amount affected, applicable period and supporting materials. MMD Business Support can assist with business-requirement coordination, document-list coordination, local communication support and project-progress coordination. Company registration, legal, tax, audit and other professional opinions should be provided by appropriately qualified appointed professional organisations.
