What Trellistry actually does.

Six modules. One shared person record. Everything runs over WhatsApp where your people already are — and nothing requires your volunteers to log in.

You pay for Core Access, then switch on the modules you need. Prices sit in bands by organisation size. See pricing →

01

People & Membership

One governed record for every person, that every other module reads from.

What it does

  • Stores households, relationships, contact preferences and consent in one record
  • Segments people by group, ministry, life stage or attendance pattern for targeted messaging
  • Runs custom forms (sign-ups, consent, updates) that write straight back to the person record — no re-typing
  • Flags duplicates, missing contact details and stale records so your data stays usable
  • Controls who can see what, with role-based permissions down to field level

What it replaces

the master membership spreadsheet and the four out-of-date copies of it.

Price

Included with Core Access

People & Membership is the core record that every other module reads from. It's included with Core Access (from S$49/month).

02

Volunteer & Serving Operations

Rostering that chases people so your coordinator doesn't have to.

What it does

  • Collects availability from staff and volunteers over WhatsApp, with automatic reminders to non-responders
  • Builds and publishes rosters against your own rules — team, ministry, frequency, blackout dates
  • Sends confirmations and shift reminders automatically before each serving date
  • Finds and requests a replacement from the same team when someone drops out
  • Keeps serving history per person, so you can see who is over-serving and who has never been asked
  • Escalates to the coordinator only when automation can't resolve it

What it replaces

the roster spreadsheet plus the WhatsApp group where nobody replies.

Proof point

One live deployment at Adam Road Presbyterian Church allocated 2,546 serving slots, engaged 490 parents at a 69% response rate, and sent 14,121 automated messages — roughly 200 hours a month (about 7 hours a day) of manual coordination avoided.

From S$79/month

03

Events & Camps

Everything that happens after the registration form is submitted.

What it does

  • Runs conditional registration — different questions by age, ministry, role or first-timer status
  • Groups families and households automatically so they register once and are placed together
  • Tracks payment status and reconciles against your own payment gateway account
  • Enforces capacity limits, waitlists and priority rules without manual sorting
  • Collects and reports transport, rooming, dietary and accessibility needs in one place
  • Produces the rooming list, transport manifest and dietary summary your committee currently builds by hand

What it replaces

the Google Form, the payment tracking sheet, and the camp spreadsheet nobody wants to own.

Proof point

One camp deployment supported ~1,500 campers, with over 50% reduction in administrative workload and registration approaching capacity within two hours of opening.

04

Care & Follow-Through

Makes sure the person who most needs a call actually gets one.

What it does

  • Reads the places your team already writes — calendar entries, meeting notes, shared documents — and finds the commitments buried inside them
  • Learns your team's own shorthand and conventions during setup, shows you every rule it has inferred, and acts only on the ones you confirm
  • Turns "I said I'd call her back" into a tracked item with an owner and a date, without anyone breaking off to file it
  • Brings one next action at a time over WhatsApp, at a moment the person can act on it, and keeps chasing until it moves or is deliberately dropped
  • Assembles the picture before a visit, session or meeting: last contact, what is still outstanding, what you meant to raise
  • Works across a team: a supervisor sees what is owed and what has gone cold without reading the notes themselves
  • Keeps the follow-through record against the person's record, with a full access audit trail and your own retention and deletion rules
  • Runs read-only if you prefer: it changes nothing in your systems, checks whether you did it yourself, and keeps reminding you until you have

What it replaces

the mental list of people you keep meaning to call back — and the handover note that never gets written.

Price

From S$79/month

Privacy note: To do its job, this module reads the working notes your staff already keep — the most sensitive material in the organisation. That is why it runs only on Trellistry Private AI and never on a public AI service. In social service and clinical settings, this obligation is at its strictest.

Scope: This is not a clinical case management system and does not try to replace one. Where an organisation already runs one, Care & Follow-Through works alongside it.

05

Partner Network

Share rooms, people and programmes with peer organisations instead of duplicating them.

What it does

  • Lists your available spaces and lets partner organisations request bookings against a shared calendar
  • Shares a directory of trainers, speakers, facilitators and specialists across the network, with availability
  • Publishes courses, camps, conferences and training events that partner organisations can open to their own people
  • Lets a parent body or network administrator control who can see and book what — or run it open, if you prefer
  • Handles cross-organisation registration, so someone from one organisation can join another's programme without a separate account
  • Reports on what's being shared, so a central office can see where resources are going unused

What it replaces

the email chain asking whether anyone has a hall free on the 14th.

The vision

Most organisations sit on rooms, people and programmes that a peer nearby badly needs. The only thing preventing sharing is that there is no shared system. Partner Network is that system.

Price

From S$49/month

Single organisation S$49/mo · Cluster (up to 10) S$299/mo · Network/denominational from S$799/mo. See full pricing →

06

Trellistry Private AI

Use AI on your most sensitive material without sending it to an external service.

What it does

  • Processes sensitive chats, case data and meeting summaries within our controlled environment — not sent to external AI services
  • Generates draft meeting minutes from authorised recordings: decisions, action items, follow-ups
  • Summarises case notes and drafts handover documents when staff change
  • Searches your own policies, handbooks and internal documents
  • Translates resources between languages
  • Reconciles and merges spreadsheets, generates timetabling drafts and reports

Every AI output is a draft for human review, never an authoritative record.

Optional

90-Day Operational Improvement Programme — S$3,800

For organisations with one operational problem expensive enough to justify us in the room. We baseline it, redesign the workflow, configure Trellistry around it, run a real cycle, and review outcomes after 90 days.

Most organisations don't need this. If your rosters live in one spreadsheet and you have a dozen volunteers, subscribe and we'll help you get set up — that's included.
