For independent bike shops
Every bike gets a tag.
Every customer gets an answer.
Chaintag is the service card for small bike shops. Tick the faults at the counter, price the job from your labour rate and parts, and give the customer a six-letter code so they can check on their bike instead of ringing you.

Paper tags get greasy. Phones never stop.
A bike comes in. The faults go on a scrap of card, the quote gets worked out on a calculator, and the customer leaves with a vague "should be Thursday". Then they ring on Wednesday. And on Thursday. Meanwhile three bikes are waiting on parts and nobody remembers which ones.
One tag, from the stand to the street.
Here's a single job through a normal Tuesday.
-
Check it in.
Name, phone, bike. Then tick what's wrong from 14 common faults in five groups: brakes, drivetrain, wheels and tyres, steering, and the full service. Chaintag gives the job a code like K7P-3QX. Write it on the tag and the customer's ticket.
-
Price it while they wait.
Tap "Add suggested labour" and the ticked faults become labour lines at your hourly rate. Add the parts. Labour, parts and total add up as you type, so you can say the price before they've zipped up their jacket.
-
Do the work.
The customer says yes, you start work. Waiting on a cassette? Mark it, and the card says so. Only the steps that make sense next are offered, and every change is timestamped.
-
Let them check for themselves.
The customer types their code into Track a job and sees where their bike is, the total and when it last moved. No phone number, no notes, nothing about anyone else. Or copy the ready-made text and send it yourself.
Built for the counter, not the boardroom.
-
Codes nobody misreads.
Six characters, shown as K7P-3QX, with no 0 and O or 1, I and L to mix up. Customers can type it in lower case, with spaces or without the dash, and it still finds the bike.
-
Quotes that add up.
Labour is minutes at your hourly rate. Parts are quantity times price. Add tax if you charge it. Rounding is done properly, to the penny, every line.
-
The board shows what's in.
Every job with its code, customer, bike, status and total. Collected bikes drop off. Filter to "Waiting for parts" when the courier turns up.
-
It stays on your counter.
Jobs are saved in the browser on your shop device. There are no accounts and no server, and your customers' details go nowhere.
-
At the stand, too.
On a phone it has a bottom tab bar you can hit with a gloved thumb. Light or dark, it follows your device.
The real app, live
Check a bike in. Go on.
This is Chaintag itself, not a video. It starts empty, just like it will in your shop. Anything you add stays in this browser and nowhere else.
- Tap New job, add a name and a bike, and tick a fault or two.
- On the service card, tap Add suggested labour, then add a part.
- Tap Mark quote ready, copy the code, and try it in Track a job.
