Core processor contracts: start the renewal 36 months out

Fiserv, FIS and Jack Henry serve most US banks on long contracts. Your negotiating window is 24 to 36 months before expiry, not the final year.

A community bank negotiates its core contract roughly once every seven years. The vendor across the table negotiates one every week. That imbalance explains most of what goes wrong, and it is why the timing of the renewal matters more than any single clause.

Three vendors, most of the market

The Federal Reserve Bank of Kansas City set out the market structure in a March 2024 research briefing. Using ABA survey data, it found that in 2022 Fiserv served 42% of surveyed banks, Jack Henry 21% and FIS 9%. Together the three served more than 70% of surveyed banks. On the credit union side (2020 data), Fiserv served 31%, Jack Henry 12% and FIS 3%, nearly half of surveyed credit unions between them.

Banks rarely leave. In the same briefing, 61% of surveyed banks had been with their provider for more than 10 years, and the authors name the cost of switching as a driver of that loyalty.

Regulators have noticed. On September 11, 2026, the FDIC, Federal Reserve and OCC issued a joint statement saying they would scrutinize core providers whose practices "unreasonably limit" community banks in due diligence or contract negotiation, as the ABA Banking Journal reported. The agencies acknowledged that a few large providers serve a significant share of the market, which weakens a community bank's negotiating position. The statement will not renegotiate your contract. It does give your board, and your examiner, a reason to read it closely.

The five clauses that decide the economics

Core agreements run to hundreds of pages. The KC Fed briefing calls their duration terms complex. Five provisions carry most of the money.

Term. Jack Henry's fiscal 2023 10-K says its outsourced core customers "typically sign contracts for seven or more years that include 'per account' fees," with minimum guaranteed payments over the term. At an ICBA convention session reported by Banking Exchange in 2018, Paladin fs partner Aaron Silva put the average core contract at 5.6 years and advised never signing for more than seven. The right term is the one that fits your strategic plan. For most banks that is not ten years.

Early termination. Read this clause as if you will be acquired, because the fee is calculated on the day you least want to pay it. Silva cited a $700 million bank whose estimated termination fee was about $120,000, until a flex credit clause pushed the amount owed on a sale to $1.1 million. The KC Fed briefing also notes that fees for changing or ending a contract early can be unclear. When FIS simplified its contract model, it dropped required term lengths, liquidated damages and exclusivity requirements. That tells you where the friction usually sits.

Deconversion. This is separate from termination: it is what the provider charges to hand your data to the next one. It is real revenue for the vendors. Jack Henry reported deconversion fees of $31.8 million in fiscal 2023 and $53.3 million the year before. An ABA Banking Journal guide to core negotiation recommends a clear fee formula, fees payable on file delivery, declining costs for follow-on file sets, time-and-resource charges only, and no cost to access your own data. Get the number written down now, while you are a customer they want to keep.

Per-account pricing and minimums. Per-account fees scale with you, which sounds fair. The problem is minimums that do not fall when you shrink, and tiers that do not reset after a branch sale or a merger. Jack Henry's 10-K also says support fees generally increase as customer assets increase. Model your fees at the account count in your three-year plan, not today's.

Add-on modules and interfaces. The core is the anchor. A lot of the margin sits in what gets bolted on: imaging, fraud, card, data feeds, digital banking connectors, and the interface fees charged to let a third party talk to the core. In the 2020 ABA survey cited by the KC Fed, more than half of banks named fees for implementation with third-party providers and fees for upgrades as the most problematic contract provisions. The ABA Banking Journal authors recommend making ancillary contracts coterminous with the master agreement and pushing for no or low third-party interface fees.

Why 24 to 36 months, not 12

Silva's guidance for a typical five-year technology contract is to start negotiating 24 to 30 months before expiration and to finish 18 to 24 months out. He calls the final 12 months the "red zone," where the bank has no negotiating power. Vendors know this. It is why they are happy to start the conversation a year out.

We would start at 36 months for a bank on a seven-year term with a heavy stack of add-ons. Negotiating power comes from a credible alternative, and a credible alternative takes time: a request for proposal, demos, due diligence under the interagency third-party guidance, board approval and a conversion plan. If the vendor knows you cannot switch in time, you are not negotiating. You are asking.

Be careful with early extensions. Silva described a "blend and extend" deal where a bank cut a $100,000 cost to $50,000 in exchange for a three-year extension, while his data showed other banks getting the same service for under $10,000. Halving an overpriced line still leaves it overpriced.

A 36-month plan

• 36 months out: Collect the master agreement, every amendment and every ancillary schedule. Build one table: product, fee basis, minimum, term end, notice window, termination formula, deconversion terms.
• 30 months: Reconcile twelve months of invoices against the fee schedule before you negotiate anything else.
• 24 to 30 months: Go to market with at least one credible alternative and tell the incumbent you are doing it.
• 18 to 24 months: Close, with term, termination, deconversion and interface fees in writing.
• Every year after: Keep the notice date on a renewal calendar with a named owner, and review add-on spend annually.

Plan for the merger now

Silva said about a third of acquired banks move to the acquirer's core. If M&A is plausible on either side, negotiate the change-in-control terms up front. The ABA Banking Journal guide lists the ones that matter: no termination or fee triggered by a change in control, a license that transfers to a successor, and reduced or waived deconversion costs when the acquirer runs the same core.

The vendors around the core deserve the same treatment, and we cover them in vendor spend beyond the core.

If your core renews in 2028 or 2029, you are already in the window. Pull the contract this quarter and build the one-page table above. If you want an independent read before the first vendor meeting, a Second Opinion covers one contract in five business days, and the Renewal Desk keeps the calendar running after that.
