Gainshare Engagement Letter Template: Key Clauses for Software Negotiation

Clause 1 — Scope

What the engagement actually covers

Defines the specific software contract or contracts being negotiated, the vendor(s) involved, the renewal window or new-purchase decision date, and the in-scope buyer entities. Example language: "Advisor will provide negotiation strategy, vendor counter-proposal support, and commercial close assistance for [Buyer]'s [Vendor] [Contract Type] renewal currently scheduled for signature by [Date]."

The scope clause is short and specific. It is not a list of methodologies, deliverables, or hour estimates — those belong in fixed-fee SOWs, not gainshare SOWs. In gainshare, the deliverable is the savings, not the process.

Clause 2 — Baseline

How the savings baseline is established

The single most important clause. Defines the baseline as the vendor's first written proposal for the renewal or new purchase. Requires the proposal to be attached as Exhibit A. Requires three countersignatures: buyer-side procurement lead, advisor, and buyer's CFO. Fixes the baseline at engagement-letter signing — it cannot be revised by either party once the engagement begins.

Example language: "The savings baseline is the Vendor Proposal attached as Exhibit A, dated [Date], with Total Contract Value of $[Amount] on the scope and term described therein. The Baseline is countersigned by Buyer, Advisor, and Buyer's CFO at signing of this Engagement Letter and is not subject to revision."

The companion glossary entry for the term is at gainshare and the deep-dive is at what counts as savings.

Clause 3 — Fee formula

The percentage and the math

States the gainshare percentage and the calculation. NoSaveNoPay's standard is 25%. Example language: "Advisor's fee = 25% × (Baseline Total Contract Value − Signed Contract Value). If Signed Contract Value equals or exceeds Baseline Total Contract Value, the fee is $0."

This clause is two sentences. It should not contain "minimum," "floor," "retainer," or any other word that conditions the fee on something other than savings. The companion deep-dive: how gainshare fees are calculated.

Clause 4 — Verification

The savings memo and CFO countersignature

Specifies that no invoice may be issued until a savings memo — listing baseline, signed value, savings, and gainshare fee — is countersigned by the buyer's CFO. Example language: "Advisor shall not invoice any fee under this Engagement Letter until Buyer's Chief Financial Officer has countersigned a Savings Memo listing the Baseline, the Signed Contract Value, the calculated Savings, and the calculated Fee. The Savings Memo is a condition precedent to invoicing."

Verification is the gating event. The CFO signature is what turns "advisor's calculation" into "buyer's acknowledged savings." Without it, no invoice. This is the clause that converts a marketing claim into a contractual guarantee.

Clause 5 — Exclusions

What does not count as savings

Lists the five categories excluded from savings: buyer-initiated scope reductions, externally driven price changes, future savings dependent on buyer execution, benchmark comparisons, and items the buyer was dropping regardless. The exclusion list lives in the engagement letter, not in a side document, so neither party can claim surprise later.

Example language: "Savings excludes: (i) scope reductions initiated by Buyer prior to engagement; (ii) price reductions announced by Vendor independent of negotiation; (iii) future savings dependent on Buyer's post-signature execution; (iv) comparisons against benchmark or list-price values; (v) items in the Baseline that Buyer had previously decided to discontinue."

Clause 6 — Termination

How the engagement ends

Either party may terminate with 14 days' written notice. If terminated before the vendor contract is signed, no fee is owed. If terminated after signature but before the savings memo countersignature, the parties cooperate on the memo and the standard fee applies if savings are confirmed. There are no termination penalties beyond unpaid fees on verified savings.

Notable: there is no minimum term, no auto-renewal, no notice acceleration clause. Each engagement is a single event ending with the savings memo countersignature.

Clause 7 — IP and confidentiality

Information protection

Confirms that all confidential information shared by either party remains the property of the disclosing party; that vendor pricing data shared with the advisor will not be used outside the engagement; and that the advisor's methodologies, templates, and benchmarks remain the advisor's IP. If the buyer has an existing NDA, this clause defers to it: "The parties' existing NDA dated [Date] governs confidentiality under this Engagement Letter."

Clause 8 — Independence representation

The vendor-relationship disclosure

NoSaveNoPay's most important non-fee clause. Confirms that the advisor takes no money from the vendor, has no reseller or referral relationship with the vendor, and will disclose any conflicts of interest before the engagement begins. Example language: "Advisor represents that it has no financial relationship with [Vendor], receives no commissions, rebates, or referral fees from [Vendor], and acts solely in Buyer's commercial interest under this Engagement Letter."

For most enterprise buyers, this clause matters as much as the fee structure. It is what separates an independent advisor from a vendor partner masquerading as one.
