building automation for a small aircon company in singapore right now. when we started, every "expert" online was telling them what they should switch to. "use hubspot." "use monday." "use [insert SaaS name here]." they didn't want any of it. they had been using whatsapp, a calendar tool they were already familiar with, and google sheets for years. they didn't want a new dashboard. they wanted the dashboard they already had to stop being a mess.
so we built around what they already use. not a new system. their existing system, but with the painful parts solved.
here's the actual stack:
- whatsapp (they were already getting most leads here from facebook ads and carousell)
- the calendar tool they already used for scheduling site visits
- google sheets as the CRM, because everyone in the office already knew how to use it
what we built:
- inbound whatsapp messages get classified by an AI router (quote, scheduling, follow-up, vague enquiry)
- the router pulls structured data into google sheets so the team has one source of truth
- it pings the founder's whatsapp for anything ambiguous, with full context
- nothing about how the team works changes, except they stop drowning
the honest part:
the calendar tool they used wasn't ideal. it had limitations. the API was patchy. some features didn't exist. we hit walls. we worked around them. that's not a complaint — that's literally what they paid us to do.
the small business owner does not want to know about the calendar tool's API getting deprecated or carousell having no public API or whatsapp business API throwing cryptic error codes that aren't actually their fault. they want the messages to get answered. they want bookings on the calendar. they want a sheet with all their leads. that's it.
most agencies make their lives harder by introducing new tools they have to learn. the actual job is: make their existing tools work without them having to think about it. take the technical bullshit on yourself. that's what they're paying for.
side effect of doing it this way: the team didn't need a single training session. nothing changed for them except things stopped slipping through.
genuine question for any small business owners reading — what's a tool an agency or consultant tried to make you switch to that you regretted? curious how often this pattern shows up.
