Kasha Google Workspace Marketplace

The Opportunity: Meet Clients Where They Already Work

Small business owners and finance operators live in Google Workspace. They receive client emails in Gmail, track finances in Sheets, schedule meetings in Calendar, coordinate with teams in Chat, and store documents in Drive. Every time they switch to a separate business tool, they lose context and momentum.

The Google Workspace Marketplace is where 10M+ organizations discover business tools that embed directly into their existing workflow. Finance and accounting apps rank among the highest-install categories, with established players reaching 155K–1M+ installs. But every competitor is a point solution — FreshBooks does invoicing, Streak does CRM, Calendly does booking. Nobody delivers the full stack.

Kasha ships the complete business management suite — invoicing, CRM, booking, AI assistant, payment tracking, ledger, and notifications — across all five Workspace surfaces (Gmail, Sheets, Calendar, Chat, Drive) as a single integrated add-on.

Strategic Value: Beyond Traditional GTM

This listing is not primarily a marketing exercise. It serves two strategic objectives that compound over time:

Product Thesis

Why Google Workspace

• Workflow proximity: 80%+ of SMB client communication happens in email. Invoice creation, CRM lookups, booking management — all should happen where the conversation is.
• Full surface coverage: Gmail (communication), Sheets (finance), Calendar (scheduling), Chat (team coordination), Drive (documents) — Kasha touches all five, no competitor does.
• Discovery mechanics: Marketplace users filter by "Works with" surfaces — the more surfaces Kasha integrates with, the more discovery paths exist.
• Competitor validation: FreshBooks' Gmail add-on (11K installs), Streak CRM (1M+ installs), Zoho CRM (242K+ installs), Copper (717K+) prove massive demand — but each only does one thing.
• SEO compounding: A single well-maintained listing generates permanent high-authority backlinks that no other channel can match.

Full integration, not an MVP

This is not a minimal viable product or a phased rollout. Kasha ships the complete integration from day one across all five Workspace surfaces. The platform already has every backend service needed — the work is connecting them to the Workspace add-on frontend. No reason to cut corners when the APIs already exist.

Integration Surfaces

Marketplace Positioning

Keyword cluster (baked into description)

invoice, invoicing, payment request, accounts receivable, billing, CRM, booking, appointment, client management, get paid, PDF invoice, payment link, follow-up, reminder, aging, reconciliation

Required marketplace assets

Gmail: Full Business Sidebar

The primary user flow — the "hero path" that the Marketplace listing, screenshots, and demo video will all showcase:

Gmail entry points

• Contextual trigger (message open): When user opens a message, the sidebar loads with CRM context, payment status, and Luma suggestions for that contact.
• Compose action: When composing a new email, the user can trigger "Insert Invoice" or "Insert Booking Link" to prefill draft content.
• Homepage trigger: Default sidebar view showing today's overdue invoices, upcoming bookings, and Luma insights.

Screenshot narrative arc (5 screens)

1. CRM context: Open a client email → sidebar shows contact profile, lifetime value, last booking, outstanding balance.
2. Create invoice: Click "Create Invoice" → line items, tax, due date pre-filled from context.
3. Send with payment link: PDF generated, draft email created with attachment and payment link.
4. Payment tracking: Invoice status (sent / viewed / paid / overdue) visible in sidebar for any client email.
5. Luma AI suggestions: "Client hasn't booked in 30 days", "Invoice #1042 overdue — send follow-up?", "Upsell: offer package deal."

CRM Sidebar: Client Intelligence at a Glance

When a user opens any email, Kasha matches the sender/recipient to the CRM database and renders a rich contact card:

New contact handling: If the email address doesn't match an existing CRM record, the sidebar offers "Add to Kasha CRM" with name/email pre-filled from the message metadata.

Booking Integration

Kasha's booking engine powers salon/wellness appointment scheduling, service consultations, and paid sessions. In Gmail:

• Sidebar view: See upcoming bookings for this contact, past appointments, and availability.
• Quick actions: "Create Booking" opens a card with service selection, date/time picker, and confirmation flow.
• Compose insertion: "Insert Booking Link" adds a branded booking page URL to the email draft.
• Calendar sync: Kasha bookings appear as Calendar events; Calendar events can be converted to Kasha bookings with one click.

Luma AI Assistant

Luma is Kasha's conversational AI assistant. In the Gmail sidebar, Luma powers proactive business intelligence that no competitor offers:

Luma suggestion types

Payment Status Tracking

When viewing any email from a known client, the sidebar shows real-time payment status for all associated invoices:

Quick actions from payment cards: "Copy payment link", "Send reminder", "Mark as paid (manual)", "View in Kasha".

Kasha Ledger for Sheets

A side-panel add-on for Google Sheets that turns a spreadsheet into a live finance console:

• Sync invoices: Pull all Kasha invoices into a Sheet with one click. Filter by status, date, client, amount.
• Aging analysis: Auto-generated aging columns (current, 30-day, 60-day, 90-day) with conditional formatting.
• Reconciliation: Match bank transactions (imported or manual) against Kasha invoices.
• Scheduled refresh: Auto-sync every hour/day to keep the Sheet current.
• Custom reports: Revenue by client, revenue by service, monthly trend, tax summary.

This mirrors the G-Accon/Xero pattern that drives 127K+ installs, but with native Kasha data rather than requiring a third-party connector.

Calendar → Invoice

Convert time spent into billable items:

• Event context trigger: When opening a Calendar event, the Kasha sidebar shows "Create invoice for this meeting".
• Auto-calculate: Duration × hourly rate = suggested line item amount.
• Batch invoicing: Select multiple events from a week/month, generate a single invoice with line items per event.
• Booking confirmation: Attach Kasha booking confirmation cards to Calendar events.

Google Chat: Approvals & Notifications

Team-oriented workflows delivered as interactive Chat app cards:

• Invoice notifications: "Invoice #1042 has been paid (CHF 450)" with quick action to view details or mark as reconciled.
• Approval workflows: "New invoice > CHF 1,000 requires approval" with Approve / Reject / Comment buttons.
• Booking confirmations: "New booking: Sarah M. — Hair Color, Thu 14:00" with quick actions to confirm, reschedule, or message client.
• Overdue alerts: Daily digest of overdue invoices pushed to a designated channel.
• Luma AI alerts: "3 clients at risk of churning this month" with actionable follow-up suggestions.

Chat integration is particularly valuable for Enterprise (one-to-many) clients where multiple team members need visibility into financial and booking activity.

Google Drive: PDF Storage & Templates

Automated document management integrated with Drive:

• Auto-store PDFs: Every generated invoice PDF automatically saved to a configurable Drive folder (e.g., Kasha/Invoices/2026/).
• Client folders: Option to organize by client: Kasha/Clients/{ClientName}/Invoices/.
• Invoice templates: Store custom invoice templates in Drive. Users can create, edit, and share templates within their organization.
• Receipt storage: Payment receipts and confirmation documents auto-filed alongside the corresponding invoice.
• Shared access: Leverage Drive sharing permissions for accountant/bookkeeper access without needing separate Kasha logins.

One App to Rule Them All

Kasha ships as a single Google Workspace add-on that spans all five surfaces. One manifest, one install, one listing, one set of OAuth scopes. The user installs once and Kasha appears everywhere they work.

Why one app, not multiple listings

The only advantage of multiple listings is more backlinks. But the right way to multiply backlinks is to list on different marketplaces (Google, Shopify, Zapier, Microsoft, Xero, QBO) — not to fragment the same product into separate listings on a single marketplace. Each external marketplace is a new domain, a new audience, and a new set of high-authority links.

Single manifest structure

Every trigger function calls the same kasha-middleware-gws-connector backend. The Apps Script layer is a thin UI shell — all intelligence lives in NestJS.

Hybrid Architecture: Apps Script + NestJS

Why hybrid?

Request flow

Middleware Connector Pattern (ADR-005)

The Google Workspace add-on backend follows the Middleware Connector Pattern established with the KYC proof of concept:

Three-repo structure

Data Flow & Service Integration

The middleware connector aggregates data from multiple Kasha Platform microservices:

OAuth Scopes & Security Strategy

Full scope set (all surfaces at launch)

Security posture

• Encryption in transit: TLS 1.2+ for all Apps Script ↔ NestJS calls.
• Encryption at rest: All invoice PDFs, payment metadata, and PII encrypted with managed KMS.
• Tenant isolation: Strict per-organization boundaries. Apps Script passes orgId; connector validates against auth token.
• Audit logging: Every add-on action (install, link account, create invoice, send invoice) logged for admin visibility.
• Data minimization: Store only what's needed for user-facing features. Deletion API for GDPR/FADP/LGPD compliance.
• Limited Use compliance: No data for ads, profiling, or ML training. Required Google API Services User Data Policy disclosure.

CASA security badge

Since we're requesting sensitive scopes (message.readonly, drive.file) and exchanging data with Kasha servers, a CASA security assessment is required. Target Tier 3 directly to unlock the security badge — a visible trust signal on the Marketplace listing that accelerates enterprise adoption. Badge takes ~3 weeks to propagate after passing. Budget: low five-figure annual line item for assessor fees + remediation engineering.

Competitor Landscape

Kasha Differentiation: Why We Win

Two Types of Marketplace: Kasha-Run vs 3rd Party SaaS

The word "marketplace" means two completely different things in the Kasha context. This distinction is critical for strategy, positioning, and resource allocation.

3rd Party SaaS Marketplace Map

Each external marketplace listing creates a new set of backlinks from a different high-authority domain, plus a new client discovery channel. The same middleware connector architecture (ADR-005) serves all of them — each marketplace just needs a different UI layer.

Architectural reuse across marketplaces

SMB → Enterprise Expansion

The Marketplace listing is one listing branded as Kasha. Feature differentiation happens based on the connected Kasha account tier:

SEO & Backlink Strategy

The Marketplace listing generates permanent, compounding SEO value for kasha.io:

Backlink sources from a single listing

Each of these links is a do-follow link from a Google-owned domain with maximum domain authority. This is more valuable than months of traditional link-building campaigns.

SEO reinforcement loop

Keyword-rich listing as SEO content

The Marketplace listing description itself is indexable content. By embedding keywords naturally (invoice, payment, CRM, booking, AI assistant, multi-currency, CHF, BRL, GBP), we create an additional high-authority page that ranks for these terms and drives organic traffic.

3rd party SaaS marketplaces as backlink multipliers

Google Workspace is the first listing. Each additional 3rd party SaaS marketplace listing (see 3rd Party SaaS Map) adds ~4–6 high-authority backlinks from a different domain. This is not to be confused with Kasha-run marketplaces (see Kasha vs 3rd Party), which are a product feature, not a distribution channel.

Growth Strategy & KPIs

North-star metric

Funnel KPIs

Growth experiments (post-launch)

• Listing A/B: Test first-line promise ("Create invoices from Gmail" vs "Get paid faster without leaving Gmail").
• Screenshot #1 framing: Time-to-value narrative (60-second demo) vs feature narrative (CRM + invoice + booking).
• Admin-first package: Provide "Admin Install & Allowlist" playbook targeting IT-friendly orgs (agencies, consultancies).
• Pilot program: 5–20 domains (mix of SMB + mid-market) before public launch. Document admin install steps.
• Review velocity: Post-activation prompt for Marketplace rating (without coercion). Target 4.5+ stars.
• "Works with Gmail" badge: Add Google promotional badges to kasha.io landing page and marketing materials.
