The problem
Service reports
Your report format, your readings and your limits. The engineer fills the report on site, the coordinator checks the red readings first, and one click gives a clean PDF with your logo. Red values stay inside your team.



Readings, units and limits for chilled water, domestic water, AMC checklists and more.

To review, pending and follow-up visits, with the out-of-limit count visible before you open anything.

Your logo, every reading with the red values marked, findings and recommendations.
The product
Each person sees only what they need: the sales coordinator, the service coordinator, and the engineer on site.
Every enquiry sits in one pipeline, with follow-up reminders and contract renewals flagged before they lapse.


The service coordinator sees every site, every contract and every engineer, and knows who is where.


No app store. The engineer opens a link and signs in with an Employee ID and a PIN. They see only their own jobs.



Nothing is left un-invoiced or unpaid because somebody forgot.


How it flows
The loop closes by itself: what an engineer finds on site comes back to Sales as a new enquiry.
Logged, with the next follow-up date
With VAT, by PDF or WhatsApp
Handed to the service team
Visits on the planner, engineers assigned
GPS check-in, report on the phone
GRN, invoice and payment followed up
What you get
Nine things that save your team time every single day.
Lines, VAT and total. Print it, save it as a PDF, or send the text on WhatsApp.
Every AMC visit until the contract ends, put on the planner in one go.
Check-in and out times, distance from the site, and time on site for every visit.
The right template for the site. A value outside its limit turns red by itself.
From collection to result, with the table to send to the lab in one tap.
See what is waiting for a GRN, an invoice or payment, and for how long.
Cost every line, see your margin before you send. Private to you, never on the client's quotation.
Engineers ask for leave, permission or an advance on the phone. The coordinator approves in one click.
Tomorrow's schedule as a table for your WhatsApp group, and the whole team's month in one grid.
Works with your accounts
Invoices stay in your approved accounting software. We connect to Zoho Books today, and a connection to Tally has been tested.
We show it working in AquaLoop, on a phone, within 48 hours. Free. If it fits, we run a one-month pilot with a few engineers and a few sites, and you decide on what you see.
Your company name and logo, your services, and your own report formats and parameters are set up for you. We load your sites and engineers, and train your team online.
