Why Generic Tools Break Down for Creative Deliverables
Creative agencies deliver subjective, high-fidelity visual assets. When agencies force creative workflows into generic tools, client collaboration turns into operational chaos.
Design Feedback Scattered Across 6 Disconnected Channels
A client leaves one note in a Slack DM, three comments on a Figma file they were never supposed to edit, another note inside an email thread, and two voice memos on WhatsApp. Your designers spend half their billable hours gathering scattered feedback instead of creating artwork. Stackon provides a single review room for every deliverable, forcing all stakeholder comments onto coordinate pins in one place.
The Friday Afternoon Unbilled Retainer Revision Creep
Creative retainers bleed profitability because clients request "quick little design iterations" that consume 4 hours of team time without an approved budget. Without automated retainer caps, agency founders either eat the unbilled hours or engage in uncomfortable billing arguments at month-end. Stackon’s Retainer Ledger automatically monitors hour caps, prompts clients for overage deposits, and protects agency margins.
Client Password Drop-Off and Portal Abandonment
Traditional client portals require clients to set up a username, remember a 12-character password, and complete two-factor authentication. Busy marketing executives and startup founders refuse to do this. They forget their login within a week and revert to emailing the agency founder. Stackon solves this with 1-click passwordless magic links: clients click from email notifications and land straight into their review canvas.
The Multi-Tool Franken-Stack Tax ($300+/Month Software Burn)
Creative agencies juggle Asana or ClickUp for tasks ($60/mo), MarkUp.io or Frame.io for proofing ($75/mo), Slack Pro for chat ($43.75/mo), an external portal for invoices ($99/mo), and Typeform for intake briefs ($35/mo). This costs over $3,700 every single year. Stackon unites project tracking, coordinate pin proofing, Slack-grade messaging, intake briefs, and retainer billing for $49/month flat.
Engineered for High-Velocity Creative Studios
Here is the operational architecture that makes Stackon the top white-labeled client portal for creative agencies.
Pinpoint Visual Annotations with Revision Diff Sliders
Clients click directly on images, mockups, and multi-page PDFs to drop numbered coordinate pins. When your designers update the asset, our side-by-side revision slider lets clients visually compare version 1 against version 2. When satisfied, clients click "Approve Cut," generating a legally timestamped sign-off record that permanently locks the deliverable.
- Multi-page PDF proofing with high-res vector rendering
- Side-by-side visual diff slider to inspect changes between revisions
- Legally timestamped approval audit logs preventing scope creep

Everything You Need to Know About Stackon for Creative Studios
Why do creative agencies need a specialized client portal instead of general project management tools like ClickUp or Asana?
Creative agencies operate on visual iterations, revision rounds, and client asset approvals. General project management platforms like ClickUp, Asana, or Monday were built for internal task tracking, not client-facing deliverable reviews. When a creative agency shares an Asana task with a client, the client sees internal clutter, cannot click on specific image coordinates to drop numbered feedback pins, and cannot view side-by-side visual revision diffs. Furthermore, sharing internal PM boards risks exposing internal margins, contractor rates, and unpolished work. Stackon acts as a dedicated client portal for creative agencies, providing strict two-sided isolation, point-and-click PDF/image proofing, formal approval audit trails, and automated retainer ledgers in a polished white-label environment.
How does visual deliverable proofing work for creative agency clients?
Visual proofing in Stackon allows clients to review brand guidelines, website mockups, pitch decks, and advertising creatives without third-party tools like MarkUp.io. Clients click anywhere on a PNG, JPG, or multi-page PDF deliverable to drop numbered coordinate pin #1. They write their feedback, tag creative leads, and upload reference files. When your designers upload revision v2, clients use an interactive side-by-side comparison slider to verify changes before clicking "Formal Sign-off," which generates an immutable timestamped approval log.
How does Stackon handle monthly retainer hours for creative studios?
Most design studios manage monthly retainers using messy spreadsheets, causing unbilled out-of-scope work on Friday afternoons. Stackon features an automated Retainer Ledger Engine: you set a monthly budget (e.g., 30 hours) with specific rollover credit rules. When a client submits a new creative request that exceeds their remaining balance, Stackon automatically flags an overage deposit requirement before your team touches Figma, billing overages directly via Stripe.
Can our agency white-label the client portal on our own custom domain?
Yes. 100% white-label custom domain mapping (such as portal.yourstudio.com or clients.youragency.com) with automated SSL certification, custom brand logo, favicon, agency accent colors, and branded email notification senders is included on all Stackon plans starting at $19/month. Your clients only see your agency brand.
Do our agency clients have to pay fees or create complex accounts?
No. All Stackon plans include 100% free, unlimited client accounts. Clients never pay anything to access your portal. To eliminate forgotten login credentials, Stackon utilizes passwordless 1-click magic links. Clients click their secure link from any email notification and land immediately in their active review room or project dashboard.
How does Stackon replace our existing 5-tool agency software stack?
A typical 5-person creative agency pays $60/month for ClickUp, $75/month for MarkUp.io, $43.75/month for Slack Pro, $99/month for a standalone portal, and $35/month for Typeform intake forms, totaling over $312/month ($3,750+/year). Stackon Studio replaces this entire stack for $49/month flat ($39/mo annual), returning over $3,100 directly to your agency net profit margins.
