Does CRM increase sales? What 51 scientific studies show

CRM increases sales and results on average across the companies studied, and the same research shows that the average hides a spread too wide to serve as a promise. A meta-analysis published in 2025 pooled 51 studies, with a combined sample of 11,081, and found a positive and significant effect of CRM on firm performance, with a pooled effect size of 0.524 (Das, Mohapatra, Pandey and Nayak, 2025). In the same paper, the prediction interval, which estimates where the effect would fall in a new context, runs from -0.239 to 0.887. Translated for the boardroom: in a company you do not know yet, CRM can pay off a lot or even make performance worse. The studies that explain this difference point to what the company builds around the system, such as analytical capability, process, leadership support and team usage, and one of them followed 80 CRM implementations without finding any improvement in profitability.

After more than 200 companies served, the question “does CRM increase sales?” reaches me in two ways: before the purchase, as a request for a guarantee, and a year later, as an accusation against the tool. Online, the answer usually comes with a round percentage. The claim that CRM increases sales by 29% circulates on statistics aggregators, attributed to a 2013 vendor report, and I could not find the original document with sample and method. That is why I only bring peer-reviewed studies here, each with its abstract checked in the journal that published it.

What does the average of CRM studies show?

The meta-analysis by Das and coauthors (2025), published in the Indian Journal of Marketing, applied a random-effects model to 51 studies that measured the relationship between CRM and firm performance. The pooled effect of 0.524 has a 95% confidence interval between 0.444 and 0.595, and the authors tested for publication bias with the trim-and-fill method. The number supports the short answer: companies with more developed CRM practices tend to perform better.

The figure that matters most to leadership is the heterogeneity. The I² of 97.25% indicates that almost all the variation between studies comes from real differences between them, in context and in method, with little room for sampling chance. The authors themselves recommend piloting the CRM strategy in the local environment before generalizing. When the prediction interval crosses zero, as it does here, the meta-analysis indicates that in a new context the effect can be null or negative, and the studies below help explain what separates one case from the other.

What happens when the company only buys the system?

The hardest study for anyone who believes in software alone is by Hendricks, Singhal and Stratman (2007), in the Journal of Operations Management. The authors analyzed public announcements of enterprise system implementations, 186 ERP, 140 SCM and 80 CRM, and tracked long-term stock returns and profitability measures such as return on assets and return on sales. For CRM, the paper concludes there is no evidence of improvement in stock returns or profitability for the firms that invested. In the same study, companies that adopted supply chain systems had, on average, positive stock returns and better profitability.

I read this result as a measure of what a purchase announcement is worth. The company that announces the implementation has bought the right to use the system, and the study cannot tell how many of these firms changed processes, trained the team or started managing the portfolio in the tool. It is the same pattern I discuss in why CRM projects fail: the failure usually lies in what the company stopped doing after signing.

CRM costs first and pays later

Krasnikov, Jayachandran and Kumar (2009), in the Journal of Marketing, separated two measures in a large sample of U.S. commercial banks. CRM implementation was associated with a decline in cost efficiency and an increase in profit efficiency, and in simple terms the bank became more expensive to run and better at generating profit. The firm’s commitment to CRM reduced the loss of cost efficiency, and time since adoption improved the performance of those who implemented. Banks that adopted early benefited less than those that adopted later, and I read this as the second wave learning from the mistakes of the first.

For whoever plans the budget, the study says the first year of CRM tends to weigh on cost before it shows up in profit. If the board demands a return in month six using last year’s operating cost yardstick, it measures the phase in which the effect is still negative.

Why does the effect of CRM depend on capability, process and usage?

Four studies help explain the spread in the meta-analysis, with different samples and measures and a similar conclusion: the system amplifies something the company needs to have or build.

Analytical capability and business design

Coltman, Devinney and Midgley (2011), in the Journal of Information Technology, surveyed 86 executives from 50 Australian organizations with significant CRM programs, half of them banks and insurers. The authors found a positive and significant relationship between superior CRM capability and performance. The effect of IT infrastructure on that capability turned out to be indirect, fully mediated by two organizational capabilities: human analytics and business architecture, which covers processes and structure. Initiatives that combined customer intimacy with cost reduction did better than those pursuing only one of the two goals.

A company with a well-configured CRM and nobody reading the portfolio, conversion and churn data ends up with the infrastructure and without the capability the study links to performance.

Support from leaders and staff

Becker, Greve and Albers (2009), in the International Journal of Research in Marketing, studied companies in four industries across ten European countries and separated the technological implementation of CRM from its organizational implementation. The results show that implementation does not improve every stage of the relationship equally, stages the authors divide into initiation, maintenance and retention of customers. Implementation only had an impact on performance when managers and employees gave it adequate support. This finding matches what I see in the field, where the team learns what is worth recording by watching what the manager asks and where the manager looks for the answer, the subject of CRM adoption.

The company’s strategic context

Srinivasan and Moorman (2005), in the Journal of Marketing, start from a tension that is still current, between positive academic studies and executives who doubted the value of CRM. With data from 106 online retailers, combining manager ratings of CRM with customer satisfaction ratings collected by an independent third party, the authors show that the company’s prior experience changes the return. Retailers with moderate bricks-and-mortar experience, and also with moderate time operating online, turned CRM into customer satisfaction better than those with little or a lot of experience. The study asks leadership to assess CRM within the company’s strategy, without expecting a fixed return from it.

Customer knowledge as the mechanism

Mithas, Krishnan and Fornell (2005), also in the Journal of Marketing, used archival data for a cross-section of U.S. firms and found a positive association between the use of CRM applications and greater customer knowledge, which in turn is associated with higher satisfaction. Knowledge gains were larger in firms that shared customer information with their supply chain partners. The outcome measured here is satisfaction, one step before the sale, and the study shows the path the effect takes: the company needs to know more about the customer and use that knowledge in service and in selling.

At the salesperson level, does CRM improve results?

At the individual level, the research by Ahearne, Srinivasan and Weinstein (2004), in the Journal of Personal Selling and Sales Management, tested an assumption almost every CRM project carries, that more usage is always better. With 131 salespeople in an operational CRM context, the authors found a curvilinear relationship between technology usage and quota attainment. At first, CRM usage improves performance, then the gain diminishes and, beyond a certain point, usage starts to hurt.

This is the study I show when leadership wants to fix adoption with more mandatory fields. If the salesperson spends the afternoon filling in what nobody reads, the tool takes time away from selling, a problem the data on salesperson selling time shows at scale. The level of usage that serves the sale covers the next step, the buying committee and the history the next team will need.

What the studies point to and how to observe it in your operation

Leadership needs signals it can pull from its own CRM. The table below translates each finding into an operating indicator, and the link between the columns is my interpretation.

What the research points to	Study	Signal you observe in the CRM
Buying the system is not enough	Hendricks and coauthors, 2007	Share of won deals that were created in the CRM before closing
Cost comes before profit	Krasnikov and coauthors, 2009	Cost of the commercial operation and margin per customer, month by month, since go-live
Human analytics turns records into decisions	Coltman and coauthors, 2011	A named data owner and dashboards used in management meetings
Support from managers and staff	Becker and coauthors, 2009	Pipeline and portfolio meetings run with the CRM on screen
Excessive usage hurts	Ahearne and coauthors, 2004	Number of mandatory fields per stage and time spent logging per deal
Customer knowledge is the path	Mithas and coauthors, 2005	Accounts with history, buying committee and next step recorded

The leadership support indicator is the one I check first, and how to run that ritual is in pipeline review meeting. The customer knowledge signal depends on reliable data, and a database full of duplicates and empty fields brings that indicator down before any analysis, as I discuss in CRM data quality.

What these data do not say

Most of the strong studies on CRM and performance are fifteen years old or more, with systems that predate the cloud, the phone as a selling tool and AI agents. The 2026 CRM costs less to start and integrates more things, and nothing guarantees that the average effect of 2005 holds today, up or down.

Countries and industries also limit the reading. The table brings together the United States, Australia and Europe, with heavy weight on banks, insurers and retail, and no study on the list covers Brazil or long-cycle B2B consultative selling. If you sell recurring services to businesses in Brazil, read these results as direction, without turning them into an estimate for your own operation.

Correlation and causation call for care. Cross-sectional studies, such as Coltman, Mithas and Srinivasan and Moorman, show that companies with more developed CRM perform better, and the reverse explanation remains possible: well-run companies invest in CRM and use it better because they were already well run. The design of Hendricks, which follows company performance after the announcement, and that of Krasnikov, which tracks banks over time, come closer to a causal effect, and even so none of them is an experiment.

The way of measuring also varies. Coltman asked executives to compare their own performance with competitors’, Srinivasan and Moorman used managers’ ratings of their own CRM, and Mithas and Becker measured satisfaction and relationship stages. Few studies measure sales revenue directly, and the answer to the question in the title almost always arrives through indirect paths.

The meta-analysis has its own limits. It appeared in a regional journal, and the abstract does not detail which performance metrics the 51 studies used or how many of them measure objective financial results. The heterogeneity of 97.25% shows that the 0.524 figure describes an average of very different contexts, and here the average says less than the spread.

What leadership does with these numbers

The evidence does not allow you to promise the board a percentage increase in sales, nor to treat CRM as an IT expense. It asks the board to approve the project as capability building, with a deadline, an owner and a measure, and the roadmap I use with leadership teams has seven steps.

1. Change the question. Write down which decisions the company wants to make with data it does not have today, such as which accounts to renew first or at which stage deals stall, and which indicators show the decision improved.
2. Record the baseline before go-live. Stage conversion, sales cycle, deal size, renewal and cost of the commercial operation for the last six months, with the same formula you will use in the reviews.
3. Budget for the first-year curve. The banking study points to cost before profit, and the budget needs to cover implementation, data cleanup, training and leadership hours.
4. Put leadership inside the system. The support Becker and coauthors measured shows up in the routine: the pipeline meeting, the portfolio review and the monthly forecast happen with the CRM on screen.
5. Name who analyzes. The human analytics capability in the Coltman study needs an owner, usually the CRM administrator or the RevOps team, with time set aside to turn records into dashboards and dashboards into meeting agendas.
6. Cut the records nobody reads. Review the mandatory fields at each stage and keep what someone uses to decide, because the Ahearne study shows that excessive usage takes performance away from the salesperson.
7. Measure over time and by segment. Compare against the baseline at six and twelve months, split by team and by customer segment, and treat the difference between teams as a clue to the missing capability before blaming the tool.

What this means for HR and L&D

For HR and L&D, the studies put training at the center of the result. Analytical capability, manager support and the right level of usage by the salesperson are behaviors the company teaches and follows up on, and none of them comes with the license. To measure the effect of training, use process usage indicators, such as deals with a scheduled next step and accounts with updated history, before and after each class.

The research shows that CRM pays off when the company builds around it the capability to use what it records, and that is the work of the in-company CRM adoption training. Classes are split by role, for leadership, sales, marketing and CS, and take place in the CRM the company already has, with the operation’s real records. The team leaves with the CRM best practices guide and the portfolio and database management manual, written for your operation, and HR gets the usage indicators to measure before and after.

Frequently asked questions

Does CRM increase sales?

On average across studies, yes: a 2025 meta-analysis of 51 studies found a positive and significant effect of CRM on firm performance. The variation between companies is very large, and a study of 80 implementations found no improvement in profitability. The gain shows up when the company combines the system with process, data analysis and usage by leadership and the team.

How long does CRM take to deliver results?

The study of U.S. banks found a decline in cost efficiency along with an increase in profit efficiency, and performance that improves with time since adoption. In practice, plan for a first year of investment and measure results from the first full sales and renewal cycle, comparing against the baseline.

Why do some companies see no results from CRM?

The studies point to a lack of analytical capability, a lack of support from managers and staff, and usage out of step with the sale, either too little or too much. In these companies the system exists and the way of working stays the same as before.

Is the claim that CRM increases sales by 29% reliable?

I could not find the original source of that number with a published sample and method. It circulates on statistics aggregators attributed to a 2013 vendor report, and that is why I do not use it to justify an investment.

Does using the CRM more always improve salesperson performance?

A study of 131 salespeople found a curvilinear relationship: usage improves quota attainment at first, the gain diminishes and, beyond a certain point, excessive usage hurts. The goal is to record what someone uses to decide.

How do you prepare the team for CRM to deliver results?

Train each role on what to record and why, in the company’s CRM and with real records, and train leadership to run management meetings inside the system. Name an owner for data analysis and measure process usage before and after the training.
