How we wire a B2B services firm in 14 working days

  1. 01

    Capture every inbound source into one routed inbox

    LinkedIn DMs, LinkedIn Sales Navigator referrals, Calendly bookings, Cal.com bookings, Tally and Typeform website forms, partner referrals, podcast listener notes, conference badge scans, webinar attendee follow-ups and inbound emails, all flow into one WhatsApp plus Slack plus email-converged inbox, auto-tagged by service offering, account tier and source, with the right account owner pre-assigned based on territory and service-line ownership before the first reply lands.

  2. 02

    AI qualifies, drafts the proposal, routes for approval

    Gemini-powered intake runs BANT and MEDDIC-style qualification (budget, authority, need, timeline, metrics, economic buyer, decision criteria, champion), then drafts a tailored proposal from your service catalog and past-engagement library within 20 minutes: scope, deliverables, milestones and indicative pricing all pulled from your firm's source of truth, not hallucinated. Multi-stakeholder approval (sales lead, delivery lead, finance) routes through your existing Slack channels with one-tap accept-and-comment, parallel approvals and an auto-escalation SLA timer if approvals stall past firm policy.

  3. 03

    WhatsApp onboarding, renewal nudges, account-health visibility

    Once the contract signs, the client gets a structured 7-step WhatsApp onboarding sequence: kickoff agenda, document checklist, Slack channel invite, account-team intros, first-week milestone preview, fortnight check-in and 30-day NPS. Account-health signals (usage delta, response-time drift, NPS movement, milestone-completion rate) feed a quarterly retainer-renewal scorecard so at-risk accounts surface 60-90 days before renewal with a Slack alert to the account owner and a recommended retention conversation script. Renewals become a planned conversation, not a quarterly surprise.

What a B2B services Growth Engine actually runs through your stack

Six workloads we build for Indian agencies, consultancies, dev shops and SaaS implementation teams. The pattern repeats everywhere: inbound is fragmented across four inboxes, the proposal cycle runs two business days, approvals live in a Google Sheet, and renewals happen because someone remembered them in a one-on-one. The Growth Engine threads all four into one lead-to-invoice system that sits on top of HubSpot, Salesforce or Zoho. Your sales team keeps the CRM they are already trained on.

Frequently asked questions

  • Does it integrate with HubSpot, Salesforce and Zoho CRM end-to-end?
    Yes. HubSpot is native via the v3 API (deals, contacts, companies, line-items, custom properties). Salesforce uses the REST API with custom-object support for our service-catalog and proposal entities. Zoho CRM is native via the Zoho REST API and Zoho Marketplace package. We sync bidirectionally so your sales team continues working in the CRM they are trained on while the Growth Engine handles capture, qualification, proposal and onboarding.
  • How does multi-stakeholder approval routing actually work in a real Indian agency?
    Proposals over a configurable threshold (₹ value, scope hours, or strategic-account flag) route through your existing Slack channels with parallel approvals: sales lead, delivery lead, and finance can approve in any order with one-tap accept-and-comment. Each approval is logged with timestamp and reviewer. An SLA timer auto-escalates if approvals stall past your firm's policy. The routing works the same whether the leadership group is three people or fourteen.
  • How are retainer-renewal nudges different from CRM-deal-reminders we already have?
    CRM reminders fire on calendar: 30 days, 60 days before renewal date. Our renewal nudges fire on account-health signals: usage delta, response-time drift, NPS movement, milestone-completion rate. An account-health score under threshold surfaces the account 60-90 days before renewal with a Slack alert to the account owner and a recommended retention conversation script. Renewals stop being a surprise.
  • How is AI proposal quality controlled: do you really trust a model to draft them?
    Three guardrails. One: every proposal draft is generated from your firm's own service catalog and past-engagement library, not from generic LLM training. Gemini is constrained to your sources via retrieval. Two: every draft requires sales-lead review before send (this is a draft-to-edit workflow, not auto-send). Three: a content quality score is computed per draft (clarity, scope completeness, pricing alignment) and drafts below threshold are flagged for rewrite. In practice, drafts are shipped at 60-80% accuracy and the sales lead spends 15-20 minutes editing instead of 2-3 hours writing.

Adjacent Growth Engine playbooks for B2B service firms

Vertical hubs and bespoke deep-dives that pair with the B2B services engine. Most B2B service firms we ship to are also handling adjacent client-facing teams (legal, CA, consulting), so the chartered-accountants and lawyers hubs frequently get bought as cross-team add-ons; the AI workflow and n8n bespokes are the operational layer most senior partners pick up first.
