Why are my sales down? How to find the cause and what to do in B2B

Sales fall because one of four numbers fell, or because existing customers buy less. Each has different causes, so find the number before choosing a fix.

Timing is the most expensive of these. Forrester (blog, Feb 24, 2026, from its 2025 Buyers’ Journey Survey) found that 68% of B2B buyers already have a front-runner vendor in mind at the start of their purchase, and that the front-runner wins 80% of the time.

Compare the last two quarters stage by stage, separate new customers from existing ones, and read the reasons behind lost deals before changing anything.

1. Put the last two quarters side by side: qualified opportunities, win rate, average deal size and days to close.
2. Split revenue into new customers and existing customers. A drop in one calls for a different fix than a drop in the other.
3. Split again by segment or industry. Declines often sit in one segment while the rest hold.
4. Read the notes on the last 20 lost deals and sort them into a handful of reasons.
5. Call five buyers who chose someone else, and ask when they first spoke to the winner.
6. Check the market: are competitors and customers in your segment reporting the same slowdown?

Business is rarely slow for everyone at once: slowdowns are uneven by industry, region and role, so check what peers and your segment see before blaming the market.

• Ask three peers in your segment how their last two quarters compare with yours.
• Read your industry association’s latest survey or index, not general headlines.
• Compare your win rate with last year. If it held while opportunities fell, the market or your prospecting is the cause; if it fell, look at your timing and your sale.
• Look at your existing customers. If they are buying less, ask them why before assuming the economy.

If the whole segment is slowing and your win rate holds, it is mostly the market. If your opportunities or win rate fall while the segment holds, it is your process.

Fix the number that fell, keep prospecting rather than cutting it, and spend the time on companies with a recent reason to buy.

• If opportunities fell: rebuild the target list from dated events such as new executives, new sites and acquisitions. Our guide to trigger events in sales lists the ones to watch.
• If win rate fell: reach buyers before they pick a favorite, and engage more of the group. A typical decision now includes 13 internal stakeholders and nine external influencers (Forrester, State of Business Buying 2026). Our buying committee guide shows how to map them.
• If deals slowed: give every open deal a dated next step, and find who else must agree. In a Gartner survey of 632 B2B buyers (May 2025), 74% of buyer teams showed unhealthy conflict during the decision, and groups that reached consensus were 2.5 times more likely to report a high-quality deal.
• If customers are leaving: call them, and check how much of your revenue sits with a few clients (customer concentration risk). McKinsey’s 2026 B2B Pulse (nearly 4,000 decision makers in 13 countries) found that buyers now cite inconsistent information across teams as the top reason for switching suppliers.
• Revisit lost deals. A company that said no last year may have a new reason this year, such as a new leader or a new site.

For the longer plan, our guide on how to increase B2B sales works through the four numbers one by one.

Do not answer a slowdown with more volume, deeper discounts or less research; each one makes the next quarter harder.

• Mass emailing. In a Gartner survey of 632 B2B buyers (June 2025), 73% said they actively avoid suppliers who send irrelevant outreach.
• Discounting first. It lowers deal size without fixing why buyers hesitated.
• Cutting prospecting time. The pipeline you skip now is the revenue you miss in two quarters.
• Chasing every lead. Spreading the team across companies with no reason to buy wastes the time you have.

Here is a diagnosis for a fictional engineering firm whose revenue fell about 30% between two quarters.

The firm won as often as before but had fewer chances. The cause: new outreach went to the same database list with a generic message, and few new companies had a reason to talk. The fix was to build the next list from owners with dated events, such as new plants and new operations leaders, and to write to each about that event. Opportunities recovered over the following quarter, while the win rate held.

Say which number fell, what you think caused it and what changes this week. A clear diagnosis calms a team more than a pep talk does.

• Share the four numbers, not only the revenue line.
• Name one cause and one change, with a date to review it.
• Protect selling time: cut internal meetings before you cut prospecting.
• Celebrate leading indicators, such as qualified accounts and meetings held, while revenue catches up.

SalesOne is AI account research and qualification for B2B teams. When opportunities fall, S1 agents search your market for companies with a dated reason to buy, keep or reject each one with a written reason, and map the people who own the problem.

In SalesOne’s production research runs in October 2026, 249 of 1,051 companies checked were kept, and all 375 buying signals behind them link their source. A person approves every message, and every approval is recorded with who gave it.
