The service
What is Custom Tools & Automations?
Custom business tools and automations are small, purpose-built pieces of software that remove a specific piece of manual work — logging leads and chasing follow-ups, letting a customer check a batch number, compiling a daily sales report, or producing quotes and catalogues from a price list — usually by connecting the systems a business already uses. They are not an ERP; they are the missing piece between the ERP, the spreadsheet and WhatsApp.
At gaa-tha a tool starts with the task that is wasting the most hours, not with a technology. We map how the work happens today, agree the smallest tool that fixes it, build it on plain web technology and the services you already pay for (Google Sheets, WhatsApp, Firebase, your billing software), and hand it over with documentation and your own logins. Most tools are live within a few weeks and pay for themselves in saved time.
Scope
What's included
- Process mapping — who does what today, in which spreadsheet or chat, and where time is lost
- Lead tracker with source tagging, status, reminders and a WhatsApp follow-up SOP
- Product batch-number or warranty lookup tools for customers, with QR codes on packaging
- Sales, stock or collection dashboards pulling from Google Sheets, Tally or your CRM
- Automated quotes, proforma invoices, catalogues and price lists generated from one master sheet
- Form-to-sheet-to-WhatsApp automations for enquiries, orders and dispatch updates
- Integrations with Google Workspace, WhatsApp Business, Zoho, Tally, Shopify and marketplaces via APIs, Zapier or Make
- Simple admin screens so your team can update data without a developer
- Role-based access, backups and hosting setup
- Documentation, training and optional monthly support
Process
How we work
Five steps, in the order they happen.
Find the bottleneck
A short session with the people doing the work to map the current process and pick the one task where a tool saves the most time or errors.
Scope the smallest tool
We write a one-page scope — inputs, outputs, users, integrations — with a fixed price and a timeline, and agree what is out of scope for version one.
Build and connect
The tool is built on plain web technology and connected to the sheets, WhatsApp, billing or CRM systems you already use.
Test with the team
The people who will use it try it on real data, and the rough edges are fixed before launch.
Launch and support
The tool goes live with documentation, training and your own logins, with optional monthly support for changes and new features.
Outputs
Deliverables you receive
- Process map and one-page tool scope
- Working tool on your domain or inside Google Workspace
- Integrations with your sheets, WhatsApp, billing or CRM
- Admin screen and role-based access
- Documentation, training session and all credentials
- Optional monthly support plan
Stack
Tools & platforms
Pricing model. Fixed project fee per tool based on the one-page scope; third-party services such as WhatsApp API, hosting or automation platforms are paid by you directly, and monthly support is optional.

Questions about Tools & automations
Answer-first, so humans and AI assistants get the point quickly.
Small, purpose-built software that removes manual work: a lead tracker with a WhatsApp follow-up SOP, a product batch-number lookup for customers, a sales dashboard pulling from Google Sheets, or automated quotes and catalogues generated from a price list. gaa-tha scopes each one to a single task, builds it in weeks and hands it over with your own logins.
The ones that happen every day, involve copying data between two places and go wrong when someone is on leave — lead logging and follow-up, daily sales reports, quotes and proforma invoices, dispatch updates to customers. We map your process in a short session and rank tasks by hours saved and errors avoided.
No. Tools are built to connect to what you already use — Google Sheets, Tally, Zoho, WhatsApp Business, Shopify, marketplaces — through their APIs or exports, or through Zapier and Make. If a system has no way to connect, we design around a simple export rather than asking you to migrate.
Scoping takes a few days; most single-purpose tools are live in two to six weeks. A lead tracker or lookup tool sits at the short end; a dashboard with several data sources or a document generator with many templates at the longer end.
Each tool is quoted as a fixed fee from a one-page scope, so the price is known before work starts and depends on the integrations, the number of users and screens, and whether you want ongoing support. Keeping version one small is how we keep the fee small.
You do. The tool runs on accounts in your name, the code and documentation are handed over at launch, and your data stays in your Google Workspace, Firebase project or server. There is no lock-in to gaa-tha.
Yes. Tools are built as responsive web apps that work on any phone browser and can be added to the home screen, with WhatsApp as the notification channel because that is where your team already is.
Tools use role-based access, HTTPS, per-user logins and backups, and run on Google or Firebase infrastructure or your own hosting. We keep customer data inside your accounts rather than ours, and document who has access to what at handover.
