WhatFlow vs Trengo: Shopify features, inbox and pricing

Key takeaways

• WhatFlow starts with the Shopify workflow and a message allowance.
• No inbox seat fee is added for seasonal order helpers.
• Evaluate Trengo’s bundle over its actual monthly or annual commitment.

The decision behind this comparison

Trengo is a multichannel customer conversation platform with team collaboration and automation. It sells bundled software packages rather than a simple charge for each WhatsApp send. This matters when a merchant with a small support team compares the minimum monthly commitment.

For a seasonal team considering a bundled service commitment, distinguish inbox versus helpdesk responsibilities before deciding which service system the store needs.

Pricing: what belongs in the comparison

Trengo displays Boost at €349 month to month, including ten users and 500 conversations per month. Its annual option shows a lower monthly equivalent with an annual conversation allowance. Those are different commercial commitments. Compare the month-to-month floor with WhatFlow’s US-dollar plans without silently converting currencies or assuming all conversation and message units are equivalent.

Check the Trengo official product and pricing information for the applicable package and billing term; a product capability does not establish that every plan includes it.

A realistic Shopify scenario

A three-person store needs a shared WhatsApp inbox but does not need ten user places. Work out whether the bundled package is still valuable when much of its included team capacity is unused.

Why WhatFlow is a strong fit for store operations

WhatFlow allows a team to choose a messaging allowance rather than a bundled user package, while retaining all features and paying no seat fees.

Feature access and the people who use the inbox

The storefront WhatsApp buttons remain free forever and can fit the Shopify theme and design. The button is an entry point, not a promise of unlimited free automated sends. Automated messaging still follows the selected allowance and applicable delivery rules. Keeping those two costs separate makes the free offering easier to understand.

Compare inbox access and seat costs using the permissions each colleague actually needs.

A worked WhatFlow cost example

For a concrete baseline, consider 1,000 sent messages in a month. Among the listed WhatFlow plans, Starter produces an app-side cost of $4.99 at that volume. This calculation uses its $4.99 base, 2,000 included sends and $0.005 rate above the allowance. It assumes a single monthly allowance and does not include tax or Meta delivery charges. It is a planning example, not a combined quote for every possible message category or destination.

Keep three lines in the budget: the application, applicable WhatsApp delivery fees, and any separate implementation or services. Meta pricing varies by destination and category, and some service or qualifying utility messages have different treatment. An app allowance does not override Meta’s rules. The current installation terms and rate pages should be checked before committing a campaign budget.

Compare a seasonal peak with the annual commitment

Use a hypothetical seasonal store with ordinary months and a brief support peak. Ask the Trengo proposal to show the month-to-month commitment, annual payment arrangement, included users and applicable conversation allowance for each scenario. Keep the annual conversation pool distinct from the monthly plan’s allowance rather than assuming they behave identically. Compare the store’s operational needs with WhatFlow’s message plan using the actual unit each provider bills. Record how extra usage and temporary staff access would be handled under the proposed terms. The question is whether the larger bundle earns its place over the complete operating period, not whether unused user capacity looks generous in isolation.

Prepare the operating process with shared inbox ownership so the trial checks the work your team will maintain.

Why WhatFlow is my Shopify recommendation

Launch the Shopify conversation in WhatFlow and keep the budget tied to its actual sending pattern. Consider Trengo when the larger service operation needs its documented scope. Compare conversation allowances with their own definitions rather than converting them into sends or quietly mixing currencies.

Before you choose a platform

• Compare month-to-month and annual commitments separately.
• Check the definition and reset of conversations.
• Conversation allowances are not interchangeable with sent messages.
