Customer Acquisition Model for Growth (2026)

A customer acquisition model in retail describes the strategies a business uses to attract new customers. It connects the audience, the offer, and the buying path.

In the increasingly competitive world of ecommerce, conversions have become harder to earn, and customer acquisition has become correspondingly more expensive. Contentsquare’s 2025 "Digital Experience Benchmarks Report" found that the business cost of an online visit rose 9% while conversion rates fell 6.1% year over year.

This guide shows how to develop a customer acquisition model using quantitative and qualitative data. You’ll learn how to identify which channels bring the most profitable customers, which ones drain the most budget, and where to adjust your strategy to create more growth.

What is a customer acquisition model?

A customer acquisition model is a structured framework that outlines how a business converts prospects into paying customers. It defines the repeatable processes and metrics required to manage revenue generation across the customer lifecycle.

Marketing campaigns generate awareness and capture leads, but the acquisition model governs how those leads convert into revenue. The model aligns marketing spend with unit economics by tracking customer acquisition cost (CAC) and customer lifetime value (CLV).

Acquisition strategies differ based on target audiences, selling channels, and product types. The table below describes common differences in how businesses frequently pursue customer acquisition according to the structure of their business.

Why customer acquisition is important for business growth

A customer acquisition strategy can help businesses grow when marketing budgets are tight and competition for attention is high. According to Gartner’s 2025 "CMO Spend Survey":

• Marketing budgets stayed flat for the year at 7.7% of company revenue.
• 59% of CMOs said they didn’t have enough budget to execute their strategy.

These figures show that it’s getting harder, not easier, for teams to get their customer acquisition initiatives funded. That means stakeholder buy-in is more important than ever. When requesting resources for your customer acquisition strategy, show how the funding will attract new customers, which channels it will fund, and how those efforts will generate a positive return on investment (ROI) over time.

A documented customer acquisition model also helps businesses measure whether their growth is profitable. Benchmarkit’s 2025 B2B SaaS benchmark found:

• Companies spent a median of $2 to acquire $1 in revenue from new customers (new customer CAC).
• Companies spent a median of $1 to acquire $1 in new revenue from existing customers (expansion CAC).

These benchmarks show why businesses should track CAC against customer lifetime value, payback period, and retention. Such analysis can reveal when acquisition spending is creating profitable growth versus when it’s outpacing returns.

Customer acquisition and retention work best together. Acquisition brings new buyers into the business. Retention improves the value of those relationships over time. Connecting both strategies helps businesses reach new audiences, increase revenue from existing customers, and build more sustainable long-term growth.

How does a customer acquisition model work?

A customer acquisition model is a strategy that helps your business reach new audiences and guide them through the conversion funnel. It defines the message that can move potential customers to the next step on your customer journey map. It also outlines the channels and timelines to use to reach the most potential customers.

The model has two layers: foundation and execution. 

The foundation layer defines the underlying logic on which you will execute acquisition efforts. It consists of a goal, a target customer, and a value proposition. 

The execution layer turns that plan into campaigns. It connects each campaign to a channel, a message, and a way to measure results.

Building a customer acquisition model

Build the model around these elements: 

• Acquisition goals tied to a clear outcome
• Buyer personas and ideal customer profiles
• Value proposition and core messaging
• Acquisition channels for customer communication
• Stakeholders involved in sales and marketing
• Content you’ll create, such as blog articles or cart recovery emails
• Segmentation strategies for mapping each audience group to the customer acquisition funnel
• Measurement tools and data infrastructure for tracking performance

Models vary by industry because customers make decisions in different ways. An ecommerce brand may use a product page to convert new shoppers, and abandoned cart emails to bring shoppers back after they leave.

A B2B software company may use webinars to explain their product, or a free trial to let the product sell itself. Comparison pages can answer questions from buyers who are weighing options. Local service businesses often rely on search ads because customers are looking for help in a specific area. Reviews and quote forms give those customers a next step.

Map each touchpoint to see the customer journey from first contact to conversion.

Building a customer acquisition model that’s right for your business

Customer acquisition models attract, nurture, and convert leads. These models vary by industry and objective.

Cookware brand Caraway enlisted Shopify to boost their acquisition efforts in the face of rising costs, increased competition, and attribution complexities. They were also facing changes to iOS privacy rules that made it harder for Caraway to collect the customer data they needed for personalized retargeting.

“We do see continued pressures and costs elevating in the customer acquisition space,” says Connor Dault, vice president of growth and digital product at Caraway. “It's what 50% of my team is focused on 100% of the time, so it's obviously a huge, huge area of priority for us.”

Caraway rebuilt their customer acquisition model around Shop Campaigns. They began incentivizing first-time customers who used the Shop app and Shop Pay checkout by boosting the value of Shop Cash in customer digital wallets.

Shop Campaigns tracked each new acquisition, and Shopify billed Caraway only when a sale closed. The model lowered acquisition costs, grew Shop app orders sixteen times, and generated more than $1 million in revenue at a cost per acquisition comparable to other channels.

Evaluate performance by comparing customer acquisition cost against recent industry benchmark data.

First Page Sage’s 2025 CAC benchmark report found:

• Ecommerce: Average CAC of $68 for B2C companies and $84 for B2B companies
• SaaS: Average CAC of $166 for B2C companies and $273 for B2B companies
• Financial services: Average CAC of $173 for B2C companies and $923 for B2B companies

Review where your metrics land to determine your next move:

• High CAC: Your acquisition model needs optimization. Refine your target audience to reduce ad waste, optimize your landing page conversion rates, or move budget to referral networks.
• Balanced CAC: Your model aligns with benchmarks and remains profitable. Scale your growth by increasing your budget in top-performing channels.
• Low CAC: Your low costs may signal that your acquisition efforts are conservative. Expand your reach by testing new acquisition channels to capture more market share.

Benchmark data highlights how different industries balance acquisition and retention spend. High-CAC sectors like SaaS require large up-front investment, making customer retention the primary focus to protect customer lifetime value. 

Low-CAC sectors like ecommerce can prioritize customer volume instead. These businesses allocate more budget to the top of the funnel to generate transactional growth.

Improving your customer acquisition strategy

Lower your acquisition costs and retain more buyers by applying five core principles to your marketing framework:

• Make your strategy sustainable
• Build in flexibility
• Find your target market
• Diversify your approach
• Track your customer lifetime value

Make your strategy sustainable

A sustainable customer acquisition strategy maintains performance over the long term. If an existing acquisition model stops producing results, reallocate the budget to an effective channel.

Before changing your acquisition framework, verify that your team has the capacity to support the transition. Gallagher’s 2025 "Employee Communications Report" found that lack of time or team capacity was the top barrier to success for communicators, cited by 49% of respondents. Overhauling a system when staff are overworked or budgets are constrained can disrupt operations or lead to project cancellation.

Sudden strategy shifts can also confuse target audiences. Clutch’s 2026 consumer research found that 70% of consumers associate long-term brand consistency with authenticity, and 41% see consistent messaging as a hallmark of authenticity. 

Keep your acquisition strategy flexible, but schedule cutovers that don’t disrupt your team’s operations or your customers’ recognition of your brand.

Build in flexibility

Shifting market conditions require adaptable acquisition frameworks. Rigid models prevent businesses from reacting to new consumer behaviors or mitigating operational risks. RRD’s 2025 "Marketing Priorities Report" found that 48% of marketers say it’s difficult to keep pace with the speed of change.

The rise of short-form video demonstrates the need for channel flexibility. Metricool’s 2025 short-form video study analyzed more than 5 million videos and 582,456 accounts. It found that the number of short-form video posts increased by 70% in one year, reaching nearly 6 million videos published by Metricool users.

Acquisition models fixed entirely on traditional advertising leave little room to test these kinds of shifts. They can also miss moments when discovery, content, and commerce start happening in the same channel. 

Makeup By Mitchell is one example. The cosmetics brand joined TikTok Shop in late March 2020. TikTok Shop later reported that the brand generated $2 million in GMV during a one-week flash sale.

Find your target market

Effective acquisition starts with clear audience segmentation. IAB’s 2025 "State of Data" report found that agencies’ main AI use case in the media campaign lifecycle was audience identification and segmentation, already adopted by about half of agencies.

The report says agencies use this approach because consumer behaviors keep shifting and audiences need continual refinement. Group prospective buyers by demographics, behavior, channel preferences, and purchase intent so each message speaks to a specific need.

Irrelevant acquisition messages can push buyers away. Twilio’s 2025 "State of Customer Engagement Report" found that 71% of consumers will abandon a purchase when the experience doesn’t feel relevant. Use segmentation to identify high-value groups with stronger conversion and retention potential, then tailor acquisition messages to their pain points.

Build ideal customer profiles (ICPs) from the segments with pain points, channel fit, and best long-term value. Then refresh those profiles as behavior changes.

Diversify your approach

Relying on a single acquisition channel exposes businesses to platform changes, privacy restrictions, and rising media costs. Gartner’s 2025 CMO survey found that digital channels now account for 61.1% of total marketing spend, while paid online channels account for 69% of digital spend.

Privacy changes make channel diversification more urgent. IAB’s 2025 “State of Data” report says the loss of addressable identifiers has pushed advertisers toward first-party data. It has also increased interest in alternative IDs and data clean rooms. Instead of relying only on third-party targeting, brands can build direct customer relationships through account creation, loyalty programs, and owned email lists.

Direct channels also reduce reliance on social algorithms and paid media. Gartner found that email was the exception to a 9% year-over-year decline in owned and earned channel allocations. It also ranked email as the top channel for customer loyalty. Litmus’s 2026 “State of Email” data found that 35% of companies see email ROI of 36:1 or higher.

Track your customer lifetime value

Customer lifetime value measures how much revenue a brand receives from a customer over the full course of their relationship. To measure profitability, use a margin-adjusted version of CLV. That means factoring in purchase value, purchase frequency, customer lifespan, fulfillment costs, and acquisition costs.

Track CLV by acquisition channel. Klaviyo’s 2025 “State of Retail Marketing” research found that 68% of retail marketers report rising customer acquisition costs, and 1 in 5 retail brands spends $251 to $500 to acquire each customer. Only 1% are seeing lower acquisition costs paired with higher customer lifetime value.

Channel-level data can change the budget decision. A search strategy may attract high-ticket buyers who make one large purchase. A paid social campaign may attract lower-ticket buyers who return more often. The first channel may win on average order value (AOV). The second may win on repeat purchase behavior.

Enhancing your customer acquisition model

Enhancing a customer acquisition model involves three strategies:

• Craft an omnichannel marketing journey
• Develop lead nurture journeys
• Track and optimize key metrics

Craft an omnichannel marketing journey

An omnichannel customer acquisition model integrates various communication channels to provide a consistent and personalized journey for each customer, regardless of how or where they interact with the brand. 

That gives customers the ability to:

• Check inventory levels online for their local retail store
• Buy items online and pick up in-store (BOPIS) 
• View products at a pop-up and receive a personalized email cart link to shop online 

Shopify pulls data from all sales channels, including your ecommerce storefront, email list, marketplace listings, point of sale (POS), and social media storefronts, and combines them in a single platform. 

When combined with third-party apps that synchronize data on both sides, you can use Shopify’s marketing automation features to target shoppers on the channels they prefer, using data you’ve already collected.

Develop lead nurture journeys

Replace costly public campaigns with targeted lead nurture journeys. Map each journey to a conversion funnel stage to deliver the content, channels, and tactics prospects need at each step. Segment the audience to scale this strategy.

Configure marketing automations to send personalized messages when customers are ready to receive them:

• Display pop-up windows to collect email addresses in exchange for a 10% discount when visitors view the boots category page.
• Send product recommendations through email based on zero-party data shared in a quiz.
• Share personalized directions to a retail store via email when a subscriber clicks the “Visit us” page.
• Promote buy online, pick up in-store (BOPIS) offers through geotargeted social media ads within a specific radius of the store.
• Send cart recovery emails that display items shoppers left in their carts.

Fragrance diffuser brand Pura needed to reach high-intent customers without increasing their advertising costs. Danielle Mathews, Pura’s senior director of integrated marketing, noted that the brand required a precise strategy to capture and retain customer attention. 

They used Shopify Audiences to segment buyers based on real shopper data instead of broad demographics. This strategy reduced Pura's customer acquisition costs by 15% to 20% and doubled their acquired customers.

Track and optimize key metrics

Track customer acquisition performance using the following metrics:

• Customer acquisition cost (CAC)
• Customer lifetime value (CLV)
• Acquisition rate

CAC

Customer acquisition cost (CAC) tracks the total investment required to win a new customer. Calculate this metric by dividing total marketing and sales expenses by the number of new customers acquired during a specific period:

Customer acquisition cost = Total marketing and sales expenses / Number of new customers acquired

For example, if you spend $10,000 on marketing in a month and acquire 200 customers, your CAC is $50. This metric helps gauge marketing efficiency. A rising CAC shows that you're spending more to acquire each customer, which signals that you need to change your marketing strategy.

CLV

Customer lifetime value (CLV) is the total revenue a business expects from a single customer account over the lifetime of the relationship. Calculate CLV by multiplying average purchase value, average purchase frequency, and average customer lifespan:

Customer lifetime value = Average purchase value x Average purchase frequency x Average customer lifespan

For instance, if an average customer spends $50 per order, buys four times a year, and remains loyal to your brand for three years, their CLV is $600. Tracking CLV helps you understand long-term business health and profitability instead of focusing solely on immediate transactional revenue.

Acquisition rate

Acquisition rate measures the effectiveness of your website conversions. Calculate the rate using this formula:

Acquisition rate = (Number of acquired customers / Total website visitors) x 100%

If those 200 acquired customers came from 10,000 website visitors, your acquisition rate would be 2%. This metric helps you spot performance gaps, as a low acquisition rate can indicate website friction or poorly targeted traffic.

Evaluate the CLV/CAC ratio to measure business sustainability. This metric compares a customer's lifetime value to the cost of acquiring them. A 3/1 ratio is the standard industry benchmark for healthy growth. A 1/1 ratio or lower means you're spending too much to acquire customers, while a ratio above 5/1 suggests you're underinvesting in marketing and missing growth opportunities.

Forecasting and optimizing your customer acquisition model

Forecasting lets you predict the long-term success of your customer acquisition model by evaluating:

• Acquisition channels and traffic sources
• Expected growth rate
• Budget and resource allocation

Acquisition channels and traffic sources

The best mix for your business depends on which channels your target customers use, and whether you have enough resources to commit to marketing on those channels. 

Consider these seven inbound channels to attract customers to your store:

• Search engine optimization (SEO): Optimize your website structure so pages rank higher in search results.
• Content marketing: This involves creating helpful resources, like guides or videos, to build trust with an audience.
• Organic social media: Brands use this channel to engage followers on platforms like Instagram without paying for ads.
• Word-of-mouth referrals: This happens when happy customers recommend your products to their peers.
• Blogging: Write informational articles on your website to attract search traffic and position your brand as a subject matter expert.
• Podcasting: Audio shows (and increasingly, their video counterparts) build a community of loyal consumers around industry-related topics.
• Community building: Forums or Slack groups give your audience a dedicated space to connect with your brand.

Use these seven outbound channels to push marketing messages directly to prospective buyers:

• Paid search advertising: Pay search engines to display your website at the top of results for specific queries.
• Social media ads: This method runs targeted, paid promotional campaigns to reach precise demographic segments.
• Email marketing: Send promotional updates and newsletters directly to a curated list of subscribers.
• Display ads: Visual banners on third-party websites catch the attention of browsing internet users.
• Influencer sponsorships: Partnering with creators allows brands to share products with an established audience.
• Direct mail: This traditional approach sends physical materials like catalogs directly to customer mailboxes.
• Cold outreach: Sales reps initiate direct contact with prospects through unsolicited emails or messages.

Learn how each channel performs in terms of reach, conversion rate, and cost. Test different options to identify which channels work best for your business. 

For example, TikTok partnered with Shopify to let retailers sell products directly through a TikTok Shop instead of directing visitors to an external online storefront.

Expected growth rate

Expected growth rate estimates how much each acquisition channel will grow your customer base over a set period. Base the estimate on: 

• Past channel results: Historical conversion data establishes a performance baseline.
• Seasonal demand: Predictable annual cycles, like holiday surges, mean temporary spikes don't indicate permanent growth.
• Budget changes: Scale growth metrics directly up or down to match increases or cuts in financial backing.
• Market conditions: Factor in external economic shifts, competitor moves, and industry trends that alter buyer behavior.

Use the previous year’s channel performance as the baseline. Review how many new customers each channel brought in during the same period. Compare that number with recent results.

Build conservative, moderate, and aggressive forecasts for each channel. Use:

• The conservative forecast when costs are rising or conversion is slipping
• The moderate forecast when the new plan stays close to recent channel averages
• The aggressive forecast when the budget and inventory can handle growth

Budget and resource allocation

More spent on marketing generally leads to greater reach and traffic, assuming the money is allocated effectively. But realistically, you don’t have an unlimited line of credit for marketing, so make every dollar count. 

Recent benchmarks give brands a starting point. Gartner’s 2026 CMO Spend Survey found that marketing budgets average 7.8% of company revenue. The CMO survey reports that marketing expenses account for 9.0% of company revenue and 9.6% of overall company budgets. 

Treat those numbers as benchmarks. Work backward from the acquisition goal and start with the number of new customers the channel needs to bring in. Multiply that number by the target cost per acquisition. Then compare the result with the expected customer lifetime value, gross margin, and payback period.
