Compare the workflows, then the cost
Stacks connects CRM, email campaigns, reviews, invoicing, scheduling, support and tasks around shared customer records. The core platform is Free with unlimited users. Specialist tools may offer deeper workflows, integrations or reporting that your business needs.
Current competitor prices have not been verified. We have omitted the previous estimates; no “typical business” savings figure is claimed.
What does Stacks replace?
Start with these seven workflow areas. Keep a specialist tool when its capabilities are essential to your business.
| Workflow | Tools to evaluate | Stacks scope to test |
|---|---|---|
| Sales CRM | Pipedrive, HubSpot | Contacts, companies, deals, pipelines and tasks |
| Email marketing | Mailchimp | Campaigns and sequences using your configured sending provider |
| Reviews | Podium | Requests and feedback; check the review-channel guides |
| Invoicing | FreshBooks | Invoices, estimates, expenses and recorded payments; evaluate accounting requirements separately |
| Scheduling | Calendly | Appointment types, availability and booking links |
| Support | Intercom | Tickets and web-form intake; not every specialist messaging channel |
| Tasks and time | Toggl | Tasks and billable time records |

How much does Stacks cost?
- Free: $0 subscription, unlimited users and contacts. The core platform stays free as you grow, with no per-user fee.
- 50 one-time AI credits are included on Free. They do not reset each month.
- Optional AI Pro: $99/month or $995/year (USD). Upgrade for continued AI use, priority support and removal of Stacks branding from customer-facing pages.
For email delivery, connect your own email provider. For online payments, connect your own Stripe account. These services may charge their own fees. Include them below when estimating your total cost.
How do I estimate my total cost?
Select the subscriptions you could replace. Enter USD prices per seat, or use one seat for a whole-business bill. Include only tools whose workflows fit Stacks; specialist features may still need a separate subscription.
This compares your inputs, not verified vendor quotes. Taxes, currency conversion, migration and implementation costs are not calculated. Values are used for this response and are not saved as a lead.
What should I check before switching?
A contact CSV import is not a complete migration of specialist data, attachments or history. Try a small representative workflow before cancelling another service. Supported exports are described in the export guide.
Stacks is independent of the companies named here. Product names identify alternatives and do not imply affiliation or full feature parity.
Frequently asked comparison questions
Is Stacks Free a trial?
No. The core Stacks platform is free with unlimited users and contacts, with no per-user subscription fee. You can stay on Free as your business grows. Free includes 50 one-time AI credits, not a monthly allowance.
What does AI Pro cost?
AI Pro is $99 per month or $995 per year in USD. It continues AI use after the Free credits, adds priority support and removes Stacks branding from customer-facing pages. The core CRM remains free.
Which costs should I include besides the Stacks subscription?
Use your own email provider to send email and your own Stripe account to accept online payments. Those services may charge fees; SMS uses your own Twilio account. Include these costs and any tools you keep on both sides of the comparison. Taxes, migration and implementation costs are not calculated.
Does the calculator guarantee savings?
No. It compares the subscription prices and additional costs you enter, not verified competitor quotes. A negative difference means Stacks costs more for that scenario. Total cost difference stays unknown until you enter both additional-cost estimates.
Can Stacks replace every feature of my current tools?
No. Specialist products may have integrations, reporting or workflows that Stacks does not cover. Test a representative workflow and check import and export limits before cancelling another service. A contact CSV import is not a complete migration of attachments or history.
