5 best Assembly client portal alternatives for agencies

Assembly supports reusable service packages, payment links, one-time purchases, subscription plans, and a public or client-only store. A new buyer can pay, create a client account, and continue into workflow automation for onboarding.

Test how the store handles client requests, intake, and multiple clients with different service packages. The path should create the right client data without asking staff to rebuild the account.

Assembly puts commerce inside a configurable workspace app. The agency connects that app to the rest of the client flow. Wayfront uses the purchased service to organize checkout, intake, delivery, and the client account from the start.

Assembly and Wayfront both let clients respond from their inbox, so email replies do not separate the products.

Test the full thread instead. Send a message with an attachment, reply from email, add another client contact, and ask the delivery team to act. Check where the reply lands, which record owns it, and whether anyone has to copy the message into another system.

Assembly currently includes 5 active contacts on Free, 50 on Starter, 500 on Professional, and unlimited active contacts on Advanced. Active contacts are client records that can sign into the client experience. Internal users are counted separately.

Model the plan with the number of people who need portal access. An agency serving companies with several stakeholders can reach a contact limit faster than an agency with the same number of single-contact clients.

Assembly publishes a 2.9% plus $0.30 card-processing fee and a 1% ACH fee capped at $10. It also adds a billing-method fee that cannot be passed to the client: 0.3% to 0.5% for invoices, 0.5% to 0.9% for subscriptions, and 0.7% to 1.5% for store sales, depending on plan.

Wayfront connects the agency's own Stripe or PayPal account and adds no platform transaction fee to client revenue. Compare the complete fee for the payment mix you expect, then confirm the payout account, refund process, statement details, and export options inside both trials.

Treat each product as a client portal platform. Build the white-label portal on a custom domain, then inspect the login, user interface, menu, labels, services, files, forms, bills, support, and current work.

Assembly lets service businesses build client apps and arrange them inside a branded portal. Wayfront gives a productized agency a ready-made client portal experience organized around purchased services, with source templates on Pro for deeper page changes. The right client portal matches the amount and kind of customization the team can maintain.

Choose deep customization when the client experience needs a custom app. A growing agency with a repeatable service may prefer a standard structure that still carries its words and brand.

Both products support client communication from the portal and replies from email. Test secure messaging, attachments, notifications, and file sharing with several client contacts. Clients log in less often when the inbox path works, but they still need clear client access when a secure action belongs in the portal.

Use one awkward conversation with an internal note, a client reply, a large file, and a second stakeholder. Watch how each platform keeps client interactions attached to the right work. A good client portal protects the account history while respecting existing client expectations.

Both products can manage client work. Assembly provides task and app building blocks inside a configurable workspace. Wayfront creates projects and tasks from the service the client bought, then uses permissions to separate staff work from the client view.

Build the same service in both products. Test task ownership, dates, staff-only details, client updates, and what changes when the service template changes.

Run a one-time service and a subscription-based service through both products. Test the service catalog, client intake, payment processing, subscription billing, refund, failed charge, and cancellation. The billing tool should make each exception clear to the client and the person who manages billing.

Assembly combines its Payments app, store, payment links, invoices, and subscriptions inside the workspace. Wayfront connects those client workflows to the agency's own Stripe or PayPal account. Compare the complete fees and decide which account should hold the payment history.

Count how many clients buy twice and how many accounts have several contacts. Test a repeat sale, a new client contact, and an account with years of orders, files, and messages.

Assembly can keep multiple apps and services available inside the workspace. Wayfront is designed for agencies that want existing clients and partners to create the next sale through repeat orders, client referrals, and reseller workspaces. That growth model matters more than whether either product can claim unlimited users or unlimited clients on one plan.

List the client apps, services, stores, payment links, automations, forms, contracts, files, permissions, invoices, and subscriptions used by one active service. Mark each item as client-facing, internal, financial, or historical.

Move only what the service needs to keep running. A custom app for another business process can remain in Assembly during the test. The goal is a working paid client journey. Recreating unused objects only adds migration work.

Record the active contacts and internal users attached to that service. This gives both vendors the same client and team scenario when you compare plan fit, permissions, and onboarding work.

Ask Assembly what can be exported for customers, invoices, payments, subscriptions, and stored payment methods. Ask Wayfront what can be imported and which records must be recreated.

Saved payment methods and active subscriptions are the risky part. Confirm whether they can transfer, whether clients must authorize payment again, and which system sends receipts during the changeover.

Run a successful payment, failed payment, refund, and cancellation before moving a live subscription. Keep the answers in the migration plan so finance and support know where to work during the first billing cycle.

Recreate the service, price, options, intake, client access, messages, and work status. Use an offer clients already buy.

Test as a new buyer and an existing client. The new buyer should pay and reach the correct intake. The existing client should find the service, buy again, receive the right messages, and see the work in the same account.

Invite a real client contact to try the mobile and email paths. Watch where they hesitate. Their behavior reveals more than an internal checklist because they bring the habits the new client portal must support.
