TL;DR: Salesforce stores every field commissions depend on, but core Sales Cloud doesn't calculate, explain or protect payouts. Teams close that gap in one of five ways: native formula fields, a custom build, Salesforce's native ICM (Spiff), a vibe-coded tool, or a third-party commission tool. A flat rate and a few reps can stay native. Tiers, accelerators, splits and frequent plan changes point to a dedicated tool, and to an agentic platform like Driven if you want the plan designed, explained and maintained for you.

It's not uncommon for teams in 2026 to still run sales commissions on spreadsheets. The deal data lives in Salesforce, the rates live in a Google Sheet someone built three finance leads ago, and the payouts get reconciled by hand at the end of every quarter. When a rep asks why their number looks different, no one can fully explain it. When finance needs an accrual, someone exports a report and rebuilds it in Excel. The process is time-consuming, error-prone, and actively eroding rep trust. It's hard to keep a sales team motivated when reps can't trust their own paycheck.

Teams that outgrow the spreadsheet usually reach for formula fields, a custom build, or a paid add-on. But tools for managing sales incentives are now moving from rules engines you configure to agents that work alongside you. Gartner predicts that 40% of enterprise applications will feature task-specific AI agents by the end of 2026, up from less than 5% in 2025. They also say that 60% of B2B seller work will be executed through conversational interfaces by 2028.

This guide breaks down five ways to track Salesforce commissions, including what each approach does well, where it breaks, and how to choose.

To calculate sales commission, multiply the commissionable sales amount by the commission rate. A $40,000 sale at 8% earns $3,200. Base-plus-commission plans add that figure to salary, and tiered plans apply each tier's rate only to the sales inside it. The hard part is agreeing which deals count and what the rate applies to.

Three core formulas cover almost every plan. Straight commission is Commission = Sales × Rate. Base plus commission is Total pay = Base salary + (Sales × Rate). Tiered commission adds up each tier separately: (Tier 1 sales × Tier 1 rate) + (Tier 2 sales × Tier 2 rate), and so on for every tier the rep reaches.

This guide shows why most payout errors come from deciding which deals count rather than from the calculation itself. It explains why tiered plans can pay very different amounts depending on whether tiers are marginal or retroactive, and it covers why payouts should be locked once approved, so later CRM changes don't alter what has already been paid.

Ask a sales rep what's driving their next paycheck, and you'll often hear all three words used interchangeably: SPIFF, bonus, and commission. They get lumped together as "extra money for selling," but they're not the same thing, and treating them like they are leads to confused reps, inconsistent payouts, and comp plans nobody can actually explain.

A SPIFF is a short-term, targeted incentive. A bonus is a lump-sum reward tied to hitting a broader goal. A commission is the ongoing, formula-based pay tied directly to sales, the core of most sales comp plans, not an add-on to it.

This guide breaks down what each one actually means, when companies use them, how they're calculated, and how they stack together so you can build a comp plan where every payout has a clear reason behind it.
