ConsultBase is the client portal platform for independent consultants who want to look like an established firm without hiring one.

Every client gets a branded portal โ€” your logo, your colors โ€” where proposals, documents, invoices, and project updates live in one place. Proposals are signed online, accepted work becomes a tracked engagement with milestones and deliverables, time entries flow into Stripe-powered invoices, and clients book meetings through your own booking page.

Under the hood is Ivy, an AI associate with 50+ real tools: she drafts proposals, logs time, chases overdue invoices, surfaces the day's priorities, and answers questions about your business from your actual data โ€” not generic advice.

ConsultBase replaces the duct-taped stack (a generic CRM, a signing tool, an invoicing app, a scheduler, a shared-folder mess) with one system designed around how consulting engagements actually flow: proposal โ†’ engagement โ†’ milestones and deliverables โ†’ invoice.

It's built by a solo founder for solo consultants and small firms โ€” flat pricing, unlimited clients on every plan, no per-seat games. Free tools (a consulting rate calculator, SOW generator, engagement letter and retainer agreement generators) are open to everyone, no signup required.

Built for solo consultants and boutique firms across strategy, operations, HR, marketing, IT, and fractional leadership โ€” anyone who sells expertise and needs to look established while staying lean.

Pricing is flat and honest: Starter $39/mo, Pro $79/mo, Firm $149/mo with full white-label. Every plan includes unlimited clients.

Start free at myconsultbase.com โ€” 14-day trial, no credit card required.

Analysis of Portalstack

Overall verdict

  • Portalstack.io appears to be a niche SaaS tool aimed at helping businesses build customer-facing portals quickly, but I don't have verified, up-to-date information confirming its reliability, pricing fairness, or customer satisfaction levels, so I can't fully vouch for its quality without direct testing or verified user reviews.

Why this product is good

  • Positioned as a solution for building client portals without heavy custom development, which can save engineering time.
  • May offer templates or pre-built components that speed up deployment for common portal use cases.
  • Likely targets small-to-medium businesses looking for an affordable alternative to fully custom portal builds.
  • As with many niche SaaS tools, it may integrate with common platforms to reduce setup friction.

Recommended for

  • Small businesses or startups needing a quick client portal without a large dev budget.
  • Teams wanting a no-code or low-code way to give clients self-service access to documents, invoices, or projects.
  • Companies evaluating lightweight portal alternatives before committing to a fully custom-built solution.
  • Users who prioritize speed of deployment over deep customization needs.

Questions & Answers

As answered by people managing ConsultBase and Portalstack.

How would you describe the primary audience of your product?

ConsultBase's answer

Independent consultants and boutique firms โ€” strategy, operations, HR, marketing, IT, and fractional executives. Anyone who sells expertise and wants to look established while staying lean.

What makes your product unique?

ConsultBase's answer

It's built around how consulting engagements actually flow: proposal โ†’ engagement โ†’ milestones and deliverables โ†’ invoice. A signed proposal automatically becomes a tracked engagement, and one click turns it into an invoice. Add Ivy โ€” an AI associate with 50+ real tools that does the admin work instead of just chatting about it โ€” and every client gets a branded portal that makes a solo consultant look like an established firm.

What's the story behind your product?

ConsultBase's answer

I spent fifteen years in operations before building software, and kept watching independent consultants run six-figure practices out of an inbox โ€” proposals as Word attachments, invoices from a second app, files in a shared-folder maze. Clients notice, and it costs consultants work they deserve. ConsultBase is the system I wished they had: one place that makes a solo practice run โ€” and look โ€” like a firm.

Why should a person choose your product over its competitors?

ConsultBase's answer

Most alternatives are generic freelancer suites built for photographers and creatives. ConsultBase speaks consulting โ€” engagements, deliverables, retainers, assessments โ€” and prices honestly: flat plans, unlimited clients on every tier, no per-seat games. And no competitor ships an AI associate that drafts proposals, logs time, and chases invoices from your real data.

Which are the primary technologies used for building your product?

ConsultBase's answer

Next.js and React on Vercel, Supabase (PostgreSQL) for data and real-time, Stripe for payments, and Anthropic's Claude powering Ivy, the AI associate.
