Running a successful Shopify store in 2026 requires more than an attractive storefront and a strong product catalog. Merchants must also manage B2B enquiries, tax requirements, unpaid orders, customer appointments, and increasingly complex operational workflows.

For ecommerce agencies, selecting the right applications is equally important. A well-chosen app can solve a client’s immediate problem without introducing unnecessary development work, complicated integrations, or manual processes.

In this guide, we review four Shopify apps across four essential categories:

  • Best Shopify request-a-quote app: Quotify
  • Best Shopify VAT and tax app: Taxify
  • Best Shopify payment reminder app: Remindly
  • Best Shopify appointment booking app: Appointify

Each app addresses a different ecommerce challenge, making this collection particularly useful for Shopify store owners, B2B merchants, service businesses, and agencies building stores for clients.

Quick Comparison of the Best Shopify Apps in 2026

App Category Best for Starting price
Quotify Request a quote and B2B sales Wholesale stores, custom products and negotiated sales $17/month
Taxify VAT and tax management EU B2B stores and merchants displaying tax-inclusive and tax-exclusive prices $9.99/month
Remindly Payment reminders Stores managing unpaid orders, draft orders, invoices or net payment terms Free
Appointify Appointment booking Service businesses, consultations, classes and bookable experiences Free plan available

Pricing and features were checked on the Shopify App Store in July 2026 and may change over time.

1. Quotify: Best Shopify Request-a-Quote App for B2B Stores

Quotify is designed for Shopify businesses that cannot always sell products through a standard fixed-price checkout.

This is common for:

  • Wholesale and B2B orders
  • Custom-manufactured products
  • Large-volume purchases
  • Equipment and industrial supplies
  • Products that require configuration
  • Services that need individual estimates
  • Orders with negotiated pricing

Instead of forcing every customer to purchase immediately, Quotify lets shoppers add one or multiple products to a quote request and submit the information the merchant needs to prepare an offer.

Key Quotify features

Quotify allows merchants to build customized request-a-quote forms, hide product prices or Add to Cart buttons, collect files and customer details, manage proposals, and convert accepted quotes into Shopify orders. It also supports integrations with tools including Google Analytics, HubSpot, Klaviyo, Zapier, webhooks and email workflows.

Important capabilities include:

  • Unlimited quote requests
  • Custom quote request forms
  • Cart-to-quote functionality
  • Product and variant selection
  • Price and Add to Cart button hiding
  • File uploads
  • Custom email templates
  • Proposal management
  • Quote-to-order conversion
  • Multilingual storefront support
  • Google Analytics tracking
  • Market-specific settings
  • CSV exports
  • API, webhook and automation integrations on eligible plans

Why Shopify merchants should consider Quotify

A standard Shopify checkout works well when prices and purchasing conditions are fixed. It is less suitable when the final price depends on quantity, delivery location, product specifications or customer type.

Quotify creates a structured sales process inside the Shopify store. Customers can submit detailed enquiries without leaving the storefront, while the merchant receives the information required to prepare an accurate proposal.

This can help reduce unstructured enquiries arriving through contact forms, phone calls and separate email conversations.

Why ecommerce agencies may find it useful

For agencies, Quotify can provide a ready-made alternative to developing a custom quotation system.

It is particularly relevant when building Shopify stores for:

  • Manufacturers
  • Wholesalers
  • Furniture suppliers
  • Commercial equipment companies
  • Construction suppliers
  • Printing businesses
  • Custom product merchants
  • B2B distributors

The form builder, proposal workflow and integrations give agencies flexibility to adapt the quotation process to different client requirements.

Quotify pricing

Quotify currently offers plans beginning at $17 per month, with a seven-day free trial. Its higher plan adds functionality such as quote PDFs, custom email addresses, price lists, AI-assisted text writing, Zapier, Klaviyo, HubSpot, REST API access and webhooks.

Best for: Choose Quotify when customers need to request personalized pricing before placing an order.

2. Taxify: Best Shopify VAT and Dual-Pricing App for EU B2B Sales

Taxify helps Shopify stores display VAT-inclusive and VAT-exclusive prices and manage VAT-related workflows for business customers.

It is especially relevant for merchants selling to both consumers and businesses across Europe.

The problem Taxify solves

A B2C customer may expect to see a final price that includes VAT. A business buyer, however, may need to see the price before VAT or apply for a valid B2B VAT exemption.

Managing these expectations manually can create several problems:

  • Confusing product prices
  • Incorrect tax expectations
  • Additional support enquiries
  • Manual VAT-number checks
  • Checkout errors
  • Friction for international B2B customers

Taxify helps merchants create a clearer tax experience directly in their Shopify storefront.

Key Taxify features

Taxify can show prices with and without VAT simultaneously, create country-specific rules, validate European VAT IDs through the VIES system, and apply eligible VAT exemptions. Merchants can also customize how VAT information appears on product, collection and cart pages.

Its main capabilities include:

  • VAT-inclusive price display
  • VAT-exclusive price display
  • Simultaneous dual-price display
  • Fixed or percentage-based tax rules
  • Country-specific VAT rules
  • EU VAT ID validation
  • Automatic tax exemption for eligible customers
  • Customer VAT profiles
  • Customizable storefront widgets
  • Template-specific display settings
  • Translatable customer-facing text
  • Shopify Plus checkout extension on the highest plan

Why Shopify merchants should consider Taxify

Tax transparency can directly influence purchasing confidence, particularly for B2B customers comparing suppliers.

Displaying both prices helps business buyers understand the net cost while allowing consumer customers to see the final VAT-inclusive amount. VAT ID validation can also reduce the need for staff to manually verify every business customer.

Taxify does not replace professional tax or legal advice, but it can help merchants implement their selected VAT rules more consistently in Shopify.

Why ecommerce agencies may find it useful

Tax requirements are often discovered late in a Shopify project. A client may initially request a conventional online store and only later explain that it serves both B2C and B2B customers across several European markets.

Taxify gives agencies a configurable solution for:

  • Dual-price storefronts
  • European B2B stores
  • Wholesale portals
  • Cross-border selling
  • VAT validation workflows
  • Tax-display customization

This can reduce the need for theme-specific custom code while making the tax presentation easier for the merchant to manage after launch.

Taxify pricing

Taxify currently starts at $9.99 per month, with pricing tiers based partly on catalog size and required functionality. VAT ID validation is available from the Basic plan, while the Shopify Plus VAT ID checkout extension is included in the Pro plan. A seven-day free trial is available.

Best for: Choose Taxify when a Shopify store needs clearer VAT-inclusive and VAT-exclusive pricing or an EU B2B VAT validation workflow.

3. Remindly: Best Shopify App for Unpaid Order Reminders

Remindly automates payment reminders for unpaid Shopify orders and draft orders.

An order can be created without being paid immediately in several common scenarios:

  • Bank transfer payments
  • Manual payment methods
  • Draft order invoices
  • Wholesale orders
  • Net payment terms
  • Pay-by-invoice arrangements
  • B2B orders requiring internal approval

Without automation, staff must regularly inspect outstanding orders and contact customers manually. That takes time, produces inconsistent follow-up, and may allow recoverable revenue to remain unpaid.

Key Remindly features

Remindly lets merchants create automated reminder sequences and control the timing between messages down to hours or days. Rules can be based on payment methods, order tags and custom filters. Merchants can also customize sender information and email templates or automatically cancel ignored orders.

Its core functionality includes:

  • Automated payment reminder sequences
  • Follow-ups for unpaid and draft orders
  • Filters based on payment method
  • Tag-based targeting
  • Custom reminder rules
  • Hour- or day-based scheduling
  • Branded email templates
  • Custom sender name
  • Reply-to and BCC settings
  • Optional automatic order cancellation
  • Payment collection tracking and reporting

Why Shopify merchants should consider Remindly

The most valuable order is not always a new order. In some cases, it is an existing order that has not yet been paid.

A structured reminder sequence can follow up more consistently than an employee checking orders manually. It can also ensure that customers receive the right message at the right time rather than a generic reminder sent to every unpaid order.

The automatic cancellation option is useful for merchants that reserve inventory for unpaid purchases. When an ignored order is cancelled according to the merchant’s rules, the associated inventory can be made available to other customers.

Why ecommerce agencies may find it useful

Remindly can be useful for agency clients operating beyond the standard card-payment checkout model.

Typical use cases include:

  • B2B wholesale stores
  • Invoice-based businesses
  • High-value purchases
  • Manual bank transfers
  • Custom-order businesses
  • Stores using Shopify draft orders
  • Merchants offering payment terms

Agencies can help clients define different reminder strategies for different payment methods or customer groups rather than relying on one universal follow-up email.

Remindly pricing

Remindly is currently listed as a free Shopify app.

Because it launched in December 2025, it is a relatively new option compared with more established email automation platforms. Merchants and agencies should test the workflow against their specific order and payment processes before applying it broadly.

Best for: Choose Remindly when the store regularly creates unpaid orders, draft orders or invoice-based transactions that require follow-up.

4. Appointify: Best Shopify Appointment Booking App for Service Businesses

Appointify turns Shopify products or services into bookable appointments.

Shopify is commonly associated with physical products, but many businesses also use it to sell time-based services and experiences, including:

  • Consultations
  • Beauty treatments
  • Personal training sessions
  • Product demonstrations
  • Equipment rentals
  • Workshops and classes
  • Photography sessions
  • Showroom visits
  • Installation services
  • Coaching calls

Appointify adds scheduling functionality directly to the Shopify purchasing experience.

Key Appointify features

Merchants can replace the standard Add to Cart button with a Book Now button, create flexible appointment slots, set custom service durations and send automated confirmations or reminders. The app also supports breaks, holidays and configurable availability.

Its main features include:

  • Book Now button for Shopify products
  • Flexible appointment availability
  • Custom service durations
  • Unlimited appointments
  • Automated booking confirmation
  • Customizable confirmation emails
  • Appointment reminders
  • Break and holiday support
  • Booking calendar
  • Multiple services on the paid plan

Why Shopify merchants should consider Appointify

Using a separate booking platform can fragment the customer experience. Visitors may move between the Shopify store, an external calendar, a separate payment page and multiple confirmation emails.

Appointify keeps booking closer to the Shopify storefront. Customers can select an available time for a relevant product or service, while the merchant manages appointments through a dedicated booking workflow.

This makes Shopify more practical for hybrid businesses that sell both products and services.

For example, a bicycle store could sell products while also offering repair appointments. A skincare brand could sell cosmetics and offer paid consultations. A furniture retailer could let customers schedule showroom visits or design sessions.

Why ecommerce agencies may find it useful

Service booking is a frequent custom requirement in Shopify projects. Building scheduling logic from scratch can require work around availability, time slots, email notifications, holidays and cancellations.

Appointify provides a simpler starting point for agencies working with:

  • Consultants
  • Salons
  • Clinics
  • Trainers
  • Tutors
  • Rental businesses
  • Workshops
  • Experience providers
  • Product demonstration teams
  • Local service businesses

The app can also help agencies expand their target market beyond traditional product-only ecommerce clients.

Appointify pricing

Appointify offers a free plan for one service with unlimited appointments. Its Pro plan currently costs $8.99 per month and supports unlimited services, with a seven-day free trial.

Best for: Choose Appointify when customers need to select a date or time before purchasing a service, session or experience.

Which Shopify App Should You Choose?

These four apps are not direct competitors. Each solves a different operational challenge.

Choose Quotify when:

  • Prices are negotiated individually.
  • Customers place large or complex orders.
  • The store serves wholesale or B2B buyers.
  • Products require custom specifications.
  • The business needs a structured proposal process.

Choose Taxify when:

  • The store sells to B2B and B2C customers.
  • Customers need to see prices with and without VAT.
  • The business validates EU VAT numbers.
  • Country-specific tax-display rules are required.
  • The merchant needs a clearer cross-border VAT experience.

Choose Remindly when:

  • Customers frequently choose manual payment methods.
  • Draft order invoices require follow-up.
  • The merchant offers payment terms.
  • Staff currently chase unpaid orders manually.
  • Unpaid orders unnecessarily reserve inventory.

Choose Appointify when:

  • The business sells appointments or services.
  • Customers must choose an available time.
  • Shopify is being used for classes, consultations or bookings.
  • The merchant wants booking and commerce in one storefront.
  • The agency is building a store for a service-based client.

Some businesses may benefit from using more than one of these apps.

A B2B supplier, for example, could use:

  • Quotify to collect quote requests.
  • Taxify to validate VAT numbers and show the correct tax presentation.
  • Remindly to follow up after an invoice or unpaid order is created.

Together, these tools can support a broader sales workflow:

Product enquiry → Quote request → Proposal → Shopify order → VAT handling → Payment follow-up

A business that sells consultations alongside products could also add Appointify to let customers schedule onboarding calls, product demonstrations or professional services.

Before combining apps, test the complete customer journey in a development or staging store. Confirm that theme elements, customer accounts, tax settings, draft orders and email workflows behave as expected.

What Ecommerce Agencies Should Check Before Recommending a Shopify App

The best application is not simply the one with the longest feature list. Agencies should evaluate how well an app fits the client’s actual operating process.

Before implementation, review:

Business fit
Identify the specific manual or customer-facing problem the app needs to solve. Avoid installing apps without a defined use case.

Theme compatibility
Test product pages, collection pages, carts, customer accounts and mobile layouts. This is especially important for apps that change buttons, prices or storefront widgets.

Merchant usability
Consider whether the client’s team can manage the app after project handover. A technically capable app still creates risk when daily operation is too complicated.

Automation requirements
Check whether the client needs APIs, webhooks, Zapier, analytics, email integrations or other external systems.

International requirements
Review supported languages, markets, tax jurisdictions and customer-account behavior.

Pricing at scale
Consider catalog size, number of services, order volume and advanced feature requirements – not only the entry-level subscription price.

Support quality
Reliable support can be as important as the software itself, particularly when an app affects checkout, pricing, customer communication or revenue collection.

Final Thoughts

The best Shopify apps in 2026 are not necessarily the tools that attempt to do everything. They are the ones that solve a clearly defined business problem without adding unnecessary friction.

Quotify helps merchants convert complex B2B enquiries into structured proposals and orders.

Taxify improves VAT presentation and validation for European B2B commerce.

Remindly automates the recovery and management of unpaid orders.

Appointify enables service businesses to accept appointments through their Shopify storefront.

For store owners, these apps can replace repetitive manual work with more scalable processes. For ecommerce agencies, they provide practical building blocks for delivering more specialized Shopify solutions without developing every workflow from the ground up.

Evaluate each app against the merchant’s real customer journey, test it carefully, and choose the solution that removes the most important barrier to conversion or operational growth.
