Rate locks and price escalation caps in QA contracts

A testing proposal can look competitive in year one and expensive by year three. The usual cause is not the day rate on the proposal but the clause that governs how it changes: annual increases at the vendor's discretion, a fixed uplift every year, or an automatic renewal at "current rates".

This post covers rate locks, index-linked escalation, caps and currency risk. It is not legal advice; ask your counsel to review the final wording.

Start with a rate lock

A rate lock fixes the quoted rates for an initial period. It protects the value of the proposal you evaluated and lets you compare vendors on like terms. Ask every vendor in the RFP how long it will hold its rates, and score the answer.

The 2023 US interagency guidance on third-party relationships says contracts may specify the conditions under which the cost structure may be changed, including limits on any cost increases. That is what a rate lock and a cap do.

Index-linked increases after the lock

After the lock, allow the vendor to propose a change no more than once in any twelve months, with written notice, and link any increase to a named, published index.

Public guidance supports this approach:

• The US Federal Acquisition Regulation describes fixed-price contracts with economic price adjustment. Adjustments may be based on established prices, on actual costs of labour or material, or on changes in labour or material cost indexes specifically identified in the contract. It also says adjustments based on labour and material costs should be limited to contingencies beyond the contractor's control.
• The UK Model Services Contract buyer guidance says an index should be independently compiled and should compensate the supplier only for changes in its cost base caused by aggregate cost increases in its market that are outside its control. Where the supply market is dominated by labour, it suggests an index linked to an appropriate labour market. It also says buyers may require the supplier to show it has pursued efficiencies before indexation applies.

For a testing vendor, the relevant cost is labour in the country where the testers work. A general consumer price index in the buyer's country may not track it.

Cap the increases

An index protects against arbitrary increases but not against a high index. Add a cap. The FAR economic price adjustment clause for labour and material, 52.216-4, states that the aggregate of increases in any contract unit price shall not exceed 10 percent of the original unit price, and places no limit on decreases. You do not have to use that figure, but it shows that a cap over the life of the contract is an established public model.

Ask for symmetry: if the index falls, the rate falls.

Watch the seniority mix

A rate card can hold steady while the cost of the service rises, because the mix of seniority changes. A team planned as mostly mid-level testers becomes mostly senior. Make any change to the agreed mix that affects charges subject to your prior written approval.

Currency risk

When the vendor's testers are paid in one currency and you are invoiced in another, someone carries exchange rate risk. Decide who, and write it down:

• Invoice in your currency at fixed rates. The vendor carries the risk and may price it in.
• Invoice in the vendor's currency. You carry the risk, and your costs move with the exchange rate.
• Invoice in your currency with an adjustment band. Rates stay fixed unless the exchange rate moves outside a stated band against a named reference rate, after which both sides share or reset.

Whichever you choose, the RFP should ask every vendor to quote in the same currency so that proposals can be compared.

What to insist on

• Rates fixed for an initial period that covers at least the first term.
• Increases no more than once a year, on written notice.
• A named index that reflects the vendor's labour costs.
• A cap per adjustment and over the term.
• Decreases when the index falls.
• Approval rights over changes in seniority mix.
• A stated invoicing currency and an agreed approach to exchange rate risk.
• No automatic renewal at new rates without your confirmation.

Common vendor positions and how to respond

"We review rates annually for all clients." Ask which index the review follows and what the cap is. A review without a formula is a unilateral increase.

"We need a fixed uplift every year to cover salary growth." Offer an index linked to labour costs in the vendor's country, with a cap.

"We can only hold rates for six months." Weigh that in your cost model. A short lock shifts risk to you and should count against the proposal.

"We invoice in our home currency." That is a choice about who carries currency risk. Price it into your comparison.

What this means for your selection

The cost model lets you enter each vendor's quote with escalation and currency assumptions and compare total cost over the term. The contract clause builder includes a rate lock and price review clause, and the red flags checker flags automatic renewals and discretionary increases.
