Why Merchants Should Connect Their POS System to Tabr: Unlock Insights You Can't Get Anywhere Else

Definition: A POS integration connects your point-of-sale system (such as Square, Lightspeed, or Toast) to another platform using a secure authorisation method like OAuth.

If you run a retail store, restaurant, café, or service business, your POS system already contains valuable data:

• Itemised receipts
• Product names
• Taxes and tips
• Payment methods
• Order timestamps
• Refunds and voids

By connecting your POS system to Tabr, you do more than share digital receipts with customers. You gain access to a unique analytics and revenue platform built on two datasets that are rarely combined:

1. Your itemised point-of-sale receipt data.
2. Tabr's growing network-level audience and transaction intelligence.

No other platform combines these two data sources in the same way. This gives merchants access to insights that are not available from traditional POS reporting, loyalty systems, or advertising platforms.

The connection takes just a few clicks using OAuth, the same secure technology used when connecting apps to platforms like Google or Xero.

Quick answer: why connect your POS to Tabr?

Merchants should connect their POS system to Tabr because it unlocks a unique set of aggregated insights created by combining:

• Your itemised receipt data
• Tabr's cross-merchant audience intelligence

This helps merchants understand:

• Which products drive repeat purchases
• Which categories are associated with higher customer retention
• How basket composition varies by customer segment
• Where new revenue opportunities exist
• How performance compares with broader market trends

The integration is available on Tabr's free-forever merchant plan, making it a zero-cost way to access insights you cannot get anywhere else.

This helps:

• Improve customer experience
• Reduce receipt-related support requests
• Increase customer loyalty
• Generate new revenue streams
• Share structured receipt data securely

What is OAuth?

OAuth is a secure authorisation standard that allows one application to access another application's data without sharing passwords.

When you connect your POS system to Tabr:

1. You click "Connect POS."
2. You sign in to your POS provider.
3. You approve access.
4. Your POS provider issues a secure access token.
5. Tabr can retrieve receipt data based on your permission settings.
6. You can revoke access at any time.

Why OAuth is better than manual data sharing

Without OAuth, sharing receipt data often requires CSV exports, API keys, developer involvement, and ongoing maintenance. OAuth eliminates this complexity.

• No password sharing
• No manual file uploads
• Permission-based access
• Easy revocation
• Automatic token refresh

What data Tabr accesses

When you authorise Tabr, it can access data needed to match payments to receipts, such as order IDs, item names, quantities, taxes, tips, payment totals, transaction timestamps, store locations, and refund information.

Tabr does not need to change your menu, pricing, or store settings.

How Tabr uses your POS data

Tabr uses POS data to help customers automatically retrieve their itemised receipts.

1. A customer pays with a linked card.
2. Tabr detects the card transaction.
3. Tabr retrieves the matching receipt from your POS system.
4. The customer sees the digital receipt automatically.

No one needs to email receipts or take photos.

Benefits for merchants

1. Better customer experience

Customers can access receipts automatically for expense claims, tax records, warranty documentation, and personal budgeting.

2. Fewer receipt requests

Your staff spends less time reprinting or emailing receipts.

3. Increased customer loyalty

Customers are more likely to return when receipt retrieval is effortless.

4. New revenue opportunities

Merchants can participate in receipt-sharing partnerships and digital commerce experiences.

5. Structured data distribution

Your itemised receipt data becomes more useful to customers and business tools.

POS systems Tabr can integrate with

Tabr is designed to support POS systems that offer OAuth-based APIs. Examples include:

• Square
• Toast
• Lightspeed
• Clover
• Shopify POS
• NCR Voyix

If your provider supports OAuth and receipt APIs, integration is typically straightforward.

How the OAuth connection process works

1. Visit Tabr. Go to tabr.co.uk and click "Connect Your POS." You can create a merchant account on Tabr's free-forever plan.
2. Select your POS provider. Choose your POS platform from the list.
3. Authorise access. Sign in and approve permissions.
4. Sync locations. Tabr imports your store locations.
5. Start sharing digital receipts. Receipts can now be matched automatically.

Is it secure?

Yes. OAuth is the industry standard for secure third-party integrations.

• No password sharing
• Encrypted tokens
• Scoped permissions
• Revocable access
• Auditability

Tabr only requests the permissions necessary to retrieve receipt and transaction data.

Common merchant questions

Will this disrupt my POS?

No. Tabr reads receipt data through your provider's API and does not interfere with checkout operations.

Do I need a developer?

Usually not. OAuth integrations are designed for self-service setup.

Can I disconnect later?

Yes. You can revoke access from your POS provider or within Tabr.

Does this cost anything?

No. Tabr offers a free-forever plan for merchants.

What if I have multiple locations?

Tabr supports syncing multiple locations under one POS account.

How merchants can create a new revenue stream using receipt data

Quick answer: Merchants can turn itemised receipt data into a new revenue stream by connecting their POS system to Tabr. Tabr enables merchants to monetise aggregated purchase insights, participate in targeted brand campaigns, and unlock commercial opportunities from data they already generate.

Most merchants think of receipt data as an operational byproduct. In reality, it is a valuable business asset. Every transaction contains structured information about products sold, basket composition, time of purchase, store location, category trends, and repeat purchase behaviour.

By connecting your POS to Tabr, this data can become a new source of revenue rather than simply a record of past sales.

The untapped opportunity in your POS data

Historically, merchants have used POS data only for processing payments, printing receipts, and basic reporting. Tabr transforms that same data into a monetisable asset through:

• Sponsored placement opportunities
• Aggregated market insights
• Brand-funded promotions
• Improved supplier negotiations
• Revenue-sharing partnerships

How Tabr helps merchants increase revenue

Tabr enables merchants to turn existing POS data into measurable business outcomes, including increased repeat purchases, higher customer lifetime value, better retention, more effective promotions, reduced churn, stronger customer loyalty, improved product recommendations, and higher average order value.

Why receipt data is so valuable

Most marketing platforms know who visited your website, who opened an email, and who clicked an advert. Very few platforms know what customers actually bought at the line-item level.

Receipt data reveals:

• Which products are purchased together
• Average spend by customer segment
• Repeat purchase patterns
• Category preferences
• Sensitivity to price changes
• Cross-sell opportunities

Why Tabr's data advantage is unique

Most business tools analyse only one dataset. POS systems show your own sales. Loyalty platforms show enrolled member behaviour. Advertising platforms show clicks and impressions. Expense tools show internal company spending.

Tabr combines two uniquely valuable datasets:

1. Your itemised receipt data — product-level details from every transaction.
2. Aggregated network intelligence — anonymised trends across Tabr's broader ecosystem.

Unique aggregated insights available through Tabr

• Which product combinations are associated with higher average order value.
• Which categories are linked to stronger repeat purchase rates.
• Which time periods generate the most profitable baskets.
• Which store locations outperform similar peers.
• Which product categories are growing fastest across the broader market.
• Which basket patterns are associated with higher retention.
• Which segments of business spending are increasing over time.
• Which categories over-index with high-frequency purchasers.

These insights are generated using aggregated and anonymised data rather than personally identifiable information.

Real-world examples of aggregated business insights

Product bundling opportunities

Tabr identifies that baskets containing premium coffee often include pastries and dairy alternatives. Merchants can use this insight to create bundles and increase average order value.

Retention-driving categories

Tabr shows that customers who purchase from certain categories tend to return more frequently. Merchants can promote these categories to improve retention.

Market trend detection

Tabr highlights product categories that are growing faster across the broader network. Merchants can adjust inventory and merchandising ahead of competitors.

Location benchmarking

Tabr compares basket composition and repeat purchase rates across similar stores. Merchants can identify what top-performing locations are doing differently.

Time-based revenue opportunities

Tabr reveals which times of day produce the highest-margin baskets. Merchants can tailor promotions and staffing accordingly.

Supplier negotiation insights

Tabr quantifies category growth, basket contribution, and product affinities. Merchants can use these aggregated insights to negotiate better supplier terms.

Ways merchants can use Tabr to grow revenue

• Increase repeat purchases — identify customers who have not returned recently and send targeted incentives.
• Raise average order value — recommend products frequently purchased together.
• Improve customer retention — detect declining visit frequency before customers churn.
• Win back lapsed customers — automatically identify customers who have stopped visiting.
• Build smarter loyalty campaigns — reward customers based on actual spending and product preferences.
• Find high-value business customers — identify professionals and companies with significant recurring spend.
• Improve product mix — see which products drive repeat behaviour and profitability.
• Benchmark performance — understand how your customer behaviour compares with broader trends across the Tabr network.

Revenue opportunities enabled by Tabr

1. Monetise aggregated insights

Brands are willing to pay for aggregated intelligence about product affinities, category trends, purchase timing, regional demand patterns, and basket composition. Merchants who contribute data to Tabr can participate in this value creation while preserving customer privacy.

2. Participate in sponsored campaigns

Consumer brands can fund promotions targeted to relevant audience segments based on aggregated purchasing patterns.

3. Strengthen supplier negotiations

Detailed product-level insights help merchants negotiate better terms with suppliers.

4. Unlock co-marketing opportunities

Brands can collaborate with merchants using data-backed campaigns.

5. Improve core sales performance

Merchants can use insights to increase retention, basket size, and customer lifetime value.

Example ROI scenario

Suppose a merchant has 10,000 monthly customers, an average order value of £25, and monthly revenue of £250,000. If Tabr-powered campaigns increase repeat visits by just 5%, the merchant could generate around £12,500 in additional monthly revenue, or £150,000 in additional annual revenue — and that excludes savings from reduced receipt support requests.

Why this matters more than traditional loyalty programs

Traditional loyalty schemes only capture data from enrolled members. Tabr focuses on aggregated analytics and does not require merchants to access personally identifiable information about individual customers. Tabr expands visibility by connecting purchases with a broader audience of consumers and businesses who use Tabr to manage receipts.

Why early adopters have an advantage

Merchants that connect early can reach Tabr's growing user base, build richer purchase histories sooner, develop better targeting models, and establish stronger customer relationships. As Tabr's network grows, the value of participation increases.

Why this matters for business customers

Many of your customers need itemised receipts for expense claims, bookkeeping, VAT recovery, tax reporting, and audit support. If retrieving receipts is difficult, it creates friction. Tabr removes that friction by delivering receipts automatically.

Merchant benefits summary

• Automatic receipt delivery — better customer experience
• Reduced support requests — less staff time
• Secure OAuth connection — no technical complexity
• Structured receipt sharing — increased utility of transaction data
• Multi-location support — scales with your business
